back to article New UK 'leccy meters remotely run via Voda 2G

British Gas is to deploy meters with embedded mobile phones, and Zigbee networking, to ensure we know how much electricity we're using, and they do too. The smart meters use Vodafone's 2G network to send back readings and allow British Gas to see exact levels of 'leccy consumption at any time, while the Zigbee connectivity …

    What about wired connectivity?

    How many customers already have some form of Broadband connection that is on 24/7?

    How many of them have a Wireless network of some form?

    Why not have a device that can be made to use the customers own wireless lan + broadband?

    Well Doh?

    This could also save the moble spectrum from overload.

    1. Turtle_Fan

      simple really

      Because connectivity and by extension, control of the meter must under no circumstances rely on the end user.

      Not to mention support costs to explain to joe public how to hook it up to the usually wpa'd router.

    2. goats in pajamas

      Because... would only work on Windows (and then not properly), there'd be no Linux version, Apple would want 30% of the electricity bill if there was an OSX version and the Government would end up accused (rightly) of being in bed with another cretinous Corporation wanting to install spyware into our homes. And the software used would probably be hacked and infected within 36 hours.

      Other than that?

      A fine idea Stanley.

    It's British gas' fault

    BG were offered 3g, powerline and regional data concentratorssolutions.

    But in theirhaste to pre-empt the govt and establish their version as a de-facto standard they stuck to the 2g.

      Does a smart meter really need a 3G connection? surely GPRS would be fine for the job, and the 2G signal is usually better.

      That said, there is no logical reason not to go for powerline internet for smartmeaters- Solves coverage issues AND opens a new revenue stream.

        What's the uplink for?

        Top of my list of questions is why British Gas has suddenly decided it needs a realtime feed of everyone's electricity usage. Let's knock down a few of the more commonly used justifications:

        (1) It allows them to do 'real time' pricing. Well, radio teleswitch has been doing this for years for the economy 7 tariffs - and no need for an uplink there. Broadcasting at UHF/VHF has already been demonstrated to be the best way of implementing this feature, even if the existing protocols need replacing for the new generation of meters. And guess what - there's shortly going to be a whole bunch of empty spectrum ideally suited to delivering this kind of broadcast service!

        (2) It allows the electricity generators to dynamically adjust supply according to demand. Well, WTF do you think the National Grid was doing for the best part of the 20th Century? Monitoring individual consumer usage would just generate vastly more data than can be sensibly used in this context - other than by building a British Gas version of Skynet.

        (3) It eliminates the need to send a meter reader round in a van. Like estimated readings already do? Like the ability to enter your meter reading on the website already does? The fact is, flesh-based meter readers will always be required because they are the only reliable way of detecting physical tampering.

        The bottom line is that I can't think of any justifiable reason why I'd want British Gas to monitor my domestic energy use in real time - so I just can't see why they need that uplink.

      powerline comms

      Yes powerline comms is possible but it is also quite expensive to implement (lots of nasty voltages) and requires local concentrators as range is limited and noise on the transmission medium is severe.

      10 years ago I was working for a meter firm and their plan was to use powerline comms to the street and GSM from there.

    Since it's there, might as well use it

    > Mobile networks aren't ideal for such things,

    Actually they sound like quite a decent fit for this application. It's not as if the meter HAS to send its readings only once at peak times on a weekday or it's lost forever. They can (and may well be) used overnight and send their readings every few days. If the SMS fails the first time, it'll be no worse than the meter reader trying to call when you're out.

    1. chr0m4t1c


      What about meters fitted where there is no signal at all?

      From memory of the 2G connection I used to get in the days when I had a 2G phone on Vodafone, that would be, er, pretty much all of the town I live in.

      1. Equitas

        There's an answer to that one .....

        If no Vodafone signal they have SIMs for a couple of other networks and if none of these work the customer has to make a landline available. Annoyed some of the shop owners in the Eastgate Shopping Centre in Inverness no end, because at the metering point in the depths of the building there's apparently no signal for any network.

      My last meter replacement was done on a Saturday, and they came almost exactly when they said they would. Although i suspect if everyone's needs to be done, Saturday may be a bit harder to get.

      Personally, i expect PAYG meters will remain the same, with the power measurement bit wired after it and seperate, mainly because if they build a PAYG power measurement meter, its another bit of hardware to be tested and certified, and they already seem to be going at the cheapest option.

    At what cost?

    We are all being told to unplug chargers when not in use, so at what cost are these devices to run. I assume the power is drawn prior to metering - nope, didnt think so (just a wild guess).

    What are they needed for anyway - we all know where our electric goes, and unless we are billed and charged daily, whats the point. For those of us on annual direct debits, just one read a year is all thats really needed (and I can do that - and enter the details into a website)

    Perhaps the tin foil brigade was right, this is just another way to monitor us all!

      Re: At what cost?

      "We are all being told to unplug chargers when not in use, so at what cost are these devices to run."

      Nothing. Chargers that aren't in use draw so little power that you need specialist gear to actually measure it. (But yes, we are always being told that.)

      1. Anonymous Coward


        Recent switched mode chargers used no meaningful power, but plenty of older transformers do use a measurable amount even when unused (that's why they stay warm). There is still a considerable amount of older kit in use in households.

        It's still arguable the power used is too small to be of concern but when you are trying to save every last penny as fuel costs rise ...

        An interesting note; my latest LED bedside lamp is brighter than the 10w halogen it replaced but it uses just 1.5w - less than many idle transformers I've tested. It just goes to show how inefficient those old power adapters really are.

      not quite

      First of all, unplugging chargers and turning appliances off instead of stand-by will have precious little effect in the greater scheme of things ( )

      Secondly, by design, the power draw is done prior to the metering for the meter's power draw (not so for the IHU [in-home unit]).

      In the future you'll get a whole palette of tariffs as opposed to today's 2. So when peeps have their IHU's can quickly glance and see a quasi-traffic light representation of their current tariff and decide accordingly.

      Plus, the thinking is that consumers would be more motivated to change habits when the results of their actions can be measured and presented tangibly in near real-time. If your (actual) billing interval is 6 months the likelihood you'd notice the positive effects of more energy efficient appliances would be negligible.

      Finally, as for the monitoring argument, me thinks that smart meters are quite dumb on the surveillance front. There's other outlets that lend themselves to more effortless and meaningful monitoring.

      The more sinister part is when adverts start rolling in to those IHU's and utilities auction them off, with extra charges to have the IHU beep to draw your attention....

      AC, as per post above....

      They can already do all of these things, just not remotely. The reason they don't is that if they get it wrong then the legal and PR penalities are considerable. Being able to do it remotely doesn't change that and any power company that thinks otherwise will be out of business faster than they can flip the switches.

      >>"It won't be long before they'll be able to have the ability to remotely turn off your supply at a switch if you haven't paid the bill."

      For which, presumably, they'd have to actually come round and install an extra remote-controlled switch.

      Unless a meter is actually designed with power disconnection hardware, it's not as if it can get a remote software upgrade to install such a capacity.

      So if you want to be paranoid, shouldn't you be trying to get 'them' to install a new meter *now*, rather than risk the possibility that somehow 'they' find a way of making disconnection circuitry small, reliable and cheap enough to be worth installing in some future generation of meters even though such hardware would be very rarely activated?

      And, as Ken Hagan pointed out, remote disconnection has all kinds of potential PR/legal problems, especially if power is removed from one or other vulnerable person.

      Illogical though it may be, I think people would be rather more likely to blame a power company for a bad outcome from a remote disconnection (like granny falling and breaking a hip after the lights go out) than they would if the same outcome happened as a result of a prepay meter running out of credit.

        If they come along and tell you they are going to change the meter, your choices are to :

        a) let them

        b) let them disconnect you from the supply

        And someone else questioned the ability to remotely turn off supplies. It is my understanding that this is one of the key parts of many smart meters, so whilst it may not be mentioned, there's a good chance it will be there.

        When you hear of large companies getting huge fines for their poor customer service, and the legendary billing cock-ups, the bet shouldn't be on whether there's an erroneous disconnection but when.

        1. Ken Hagan Gold badge

          Re: Err

          The original remark was about someone coming home to discover that the power company had turned off their freezer. No law has been passed mandating that all freezers should be remotely controllable, nor that the power company has a right to enter your home to upgrade your freezer.

          The meter has always been the property of the power company. It is therefore uncontroversial that they have a right to maintain or upgrade it. Everything downstream of the meter belongs to you and it remains your decision whether you buy remotely controllable devices and whether you enable that feature when you get it home.

          1. Steven Roper

            @Ken Hagan

            "...your decision whether you buy remotely controllable devices..."

            The problem with that is, once the new infrastructure is in place, we will start to see more and more "remote-control-compatible" (RCC) devices in the stores, which will edge out and ultimately replace the old ones. A good example is CRT monitors - you try and buy one now. They're only available in specialist shops and they now cost an arm and a leg. Eventually you won't be able to buy them at all. Things like freezers and washing machines will go the same way - all new available models will come with RCC built in.

            It doesn't even have to be legislated: the common interests of the corporations and governments in micromanaging our private lives will simply see the RCC devices replace non-RCC ones on the shop shelves until you have no choice left once your old one fails.

      >>"Firstly, some petty crook at HQ can deduce exactly when the house is empty - and send his mates round with a van."

      Sure, since anyone and everyone working for the electricity company will have free and unmonitored access not only to raw meter data, but to related address details, etc.

      And the employees will necessarily be less trustworthy then people currently working at ISPs or phone / mobile phone companies, postal workers, etc, who also potentially have information about when houses seem to be unoccupied.

      >>"Secondly, some petty perv at HQ can guess when daughter comes home from school (10kW spike from the shower)."

      Sorry to puncture your bubble, but if someone already knows that you have a school-age daughter, wouldn't they already be able to make a pretty good guess about when she'll be coming home from school, given even just the common knowledge that schools tend to finish about the same time?

      And at least, unlike hundreds/thousands of people within walking distance of your house, someone in electricity HQ probably won't know whether your daughter is stunningly attractive and devoted to personal grooming, or a right minger who's so lardy it takes her ten minutes in the shower to get wet all over.

      If you're seriously worried about someone miles away /potentially/ knowing less about your family than almost anyone in your neighbourhood who's even slightly interested in you, that does seem like an odd set of priorities.

        So what?

        Doesn't it generally make sense to have an electricity system that has flatter demand, since that requires less generating/distribution capacity, and lower costs overall?

        In the case where there are problems with generation/transmission, might it not be better to have some capacity for shifting demand that isn't urgent to quieter periods?

        >>"This is not about providing the consumer with cheaper electricity, it is about providing the electricity providers with more profits."

        So what mechanisms stop companies just putting prices up /now/ if all they want to do is make more profit?

        If there isn't anything stopping them, then why aren't they doing it already?

        If there is something, yet smart meters would allow them to cut costs without that being reflected in prices they charge, then the fault would lie with the regulation mechanism, rather than the power companies.

        If the power companies are all complete bastards /and/ regulation is too weak, then surely we'd be screwed pretty much the same way with or without smart meters?

      500kByte a day I was told... in all seriousness

      I agree the data should come to a couple of kB/day or even meter id/date/time/start/+24 measurements can easily be squeezed into a single SMS.

      However, apparently the reality is that the meters are uploading 500kByte/day - as discussed with people in India and elsewhere implementing such a scheme. They upload the complete history every time it seems. Completely unbeleiveable and (still only 15Mbyte a month) - but on GSM thats quite an overhead. The guy I was talking to reckoned on 10K subs taking 5 minutes to do the nightly reading. I told him that was bollocks and M2M is doomed to fail if that was the assumption he was working on.

        The amount of data can vary depending on what each utility wants. It can be as little as a daily reading or as detailed as 1-second slices of a daily cycle.

        No meter sends the entire history twice. They only send a hash number to ensure integrity of previously sent data. If the hash check is successful the data gets deleted locally. If the hash fails, the data is resent and remain locally until a successful hash check.

        Finland, being one of the most advanced countries in terms of tel/co infrastructure, is probably not hampered in its 3G/LTE efforts by keeping good old 2G alive.

      This is about electricity companies making money. The aim here is to charge more money for less electricity so that they can make bigger profits for shareholders. Companies exist for no other reason than to make a profit for their shareholders -- this is nothing to do with saving the environment because that is not the primary function of a company.

    change of meter

    I recently was contact by Scottish power telling me they would need to come and change the meter at my work as it was over 20 years old. The electrician came and swapped the meter which took him about half an hour, when he was finished i asked him 'so does this mean that you can now read the meter without having to come out, is it one of the smart meters?'

    'No' he replied 'they will be fitted within the next 12 -24 months?'

    So they are wasting money replacing meters now and then going to come back and do the same again in 1 to 2 years time fitting a smart meter.

    Also if its only British Gas thats fitting these meters atm what happens if you have it fitted under British Gas supplying your electric then move to another power company a week afterwards,will the new power company then have to come and replace the BG meter with there own version?

    Surely it should be the National Grid putting these meters in not individual suppliers?

    1. David_H

      And BG

      I had my 1950's electricity meter replaced last month as it's connected timer was not working correctly. I asked the BG fitter about Smart Meters and he said that he had them on the van, but could not fit any Smart meter as he hadn't been on the Smart Gas Meter course yet - even though we are an electricity only house!

      We used to have a Smart Meter out our previous property fitted by First:Utility, and although it only reported once every day (via GSM), and in 15 minute intervals, it was invaluable in training my teenagers in turning kit/lights off. (The local display updated every few seconds).

      When we were on holiday, with most things turned off, you could actually see the regular spikes where the fridge and freezer powered their pumps.

    2. Anonymous Coward

      Simple really....

      Meters are not changed just for sake of it at regular intervals.

      Here's my (well) educated guess:

      1) Scottish power ran tests on a handful of meters from the same batch as yours (or was it your meter taken for just such a test; who knows)

      2) In their internal metrology lab they discovered that the inaccuracy of the meter is enough to necessitate a swap now instead of waiting up to 2 years to get a replacement meter in. (Remember, by law, all ageing-related inaccuracies must be in favour of the consumer)

      3) You mentioned "at your workplace". Then my guess is that the bills we're talking about aren't just a small flat but much more substantial hence the inaccuracies would add to much more, more quickly.

      Finally, it's impossible for the national grid to take over such vital assets to each utility. What they instead tried to do is to ensure common standards and interoperability which is precisely what Centrica is trying so hard to undermine :)

      The present change is for Safety reasons. These meters have a finite life. Yours has reached that. If Scottish Power had not done that and as you wanted waited for the new ones to be fitted, the would be in breach of their OFGem License. You would be the first to start complaining if it failed and blew up your house while you were out.

It'd be like the old pagers where if it was turned off or out of coverage when a message was sent to you, you'd never receive it.

    Why do they need to individually control my fridge anyway?

    Would it not be better to send a broadcast message telling all fridges in a certain area to avoid powering on for 10 minutes (or whatever) at peak times?...

    Otherwise they need to send a message to every fridge individually in the target aread which means either having a permanent data link or SMS to each meter > fridge.

    If they really need to individually address every component in the home that is just dumb/ bandwidth wasting/bad design stupidity. So now the telecoms network is going to fall over (like on New Years eve) every tea-time/FA cup Match because there are going to be millions of messages sent in the same instant preventing your kettle from boiling.

    Furthermore it doesn't save energy at all, or make my stuff consume less or be more efficient - it merely delays the fridge coming on when it should so the fridge will consume even more power when it sdoes come on (=less efficient)... Yeah whose fucking benefitting now?

    What fuckwit thought this is a good idea?

      >>"Furthermore it doesn't save energy at all, or make my stuff consume less or be more efficient - it merely delays the fridge coming on when it should so the fridge will consume even more power when it sdoes come on (=less efficient)... Yeah whose fucking benefitting now?"

      But if power is more cheaply available at some times than others, even if there was no change in overall consumption, it could cost you less (or at least less than it otherwise would) and the electricity company less if your fridge's usage was less continuous.

      In any case, when it's simply a case of delaying things for a few minutes to avoid a particular short spike, any difference in your fridge's overall consumption seems likely to be negligible, though if you really want to be pedantic, if the overall result was the fridge being fractionally warmer for a brief time, wouldn't that, if anything, tend to make the overall power consumption fractionally *lower*, since the marginal warming during the powered-off few minutes would result in a lower temperature difference across the insulation, and hence less inward heat flow requiring subsequent removal than would otherwise have been the case?

      For a sealed fridge, the cooler the contents are, the more power it takes to counter the resulting faster inward heat flow, so a turning-off of cooling for any period of time, short or long, should result in less heat overall having to be moved from the interior.

    The grid is very clunky

    I have to work with utility companies and YEDL a lot as we put 5MVA at work for our DC's.

    It's impressive just how antiquated the grid is and how they have so little information on how much power is being used by what. If you want more power they have to send a bod out with a clamp meter to the nearest sub station to measure it as they've no way of remotely monitoring it.

    Having the ability to monitor the exact usage of every home will be useful for them as it'll save money inaccurate estimations and employing meter readers.

    The real desire is to do capacity management, whereby they can cut power to non-essential domestic equipment remotely when there's a shortfall in demand. So, for example if there was a huge demand, if they could turn off all our fridges for 30 minutes then the power saved would cover that shortfall, fridges would be efficient enough that your food wouldn't go off it they were unplugged for that period. The only way to do this though would be to rewire everyone's house and have dedicated circuits for different systems which can be enabled / disabled remotely, and ensure that you don't plug in anything into the wrong circuit. Would cost an unbelievable amount of money and disruption, maybe for new builds but that's it

    1. Anonymous Coward

      Better to have something like X10 power line control - or is that too obvious?

      Of course the power compaines want to do consumption management (not capacity management) but they will need to switch off 100,000's of fridges (with say 10% duty cycle) to make any meaningful reduction in consumption.

      Thy certainly don't need to address my fridge individually - they need to boradcast to everything that can be powered down. So using GSM for such is folly.

      Probably Not True...

      The only way to do this though would be to rewire everyone's house and have dedicated circuits for different systems which can be enabled / disabled remotely, and ensure that you don't plug in anything into the wrong circuit.


      The way this would be achieved would be more straight forward. NEW household appliances would be built with a reciever (parhaps something similar to a reduced functionality X10 system) which would also be built into the meter..

      At times of high demand (i.e. just before the advert break) the meters will recieve a signal to broadcast a "10 minute hold-off" for non essential appliances - appliances that would have to contain the hardware to act upon this signal.

      To the people saying that everyones fridge suddenly drawing current at the end of the "peak demand" period being no better than everyone brewing up... Kettle = 3Kw, Fridge 0.3Kw

      And to those whining about defrosted fridges / freezers or excessive energy use becuase it isn't working "optimally" - 10 minute interuption is nothing and you will SAVE more money buying a more efficient fridge (with the technology built in) than running your old one without it...

    Isn't 2G only a bit shortsighted?

    What would concern me about these meters is that the mobile technologies are likely to progress very quickly over the next while and 2G GSM will disappear faster than a lot of people think.

    At present, the major problem with UMTS-3G is that it's stuck on the 2100MHz band which is giving it relatively poor signal propegation characteristics comapred to GSM-900Mhz.

    Once the licensing and auctioning of spectrum is complete, you'll find that mobile operators will move very quickly to using their 900Mhz spectrum for 3G/4G services. The majority of mobile phones already support both GSM and UMTS, and their life expectancy is typically only a year or two at most so, there's no real difficulty in switching over to exclusivley 3G networks. It is not in any mobile operators interest to continue using GSM beyond its "best before" date as UMTS makes far more efficient use of the available, and very expensive, spectrum allocations that each operator has. So, if you ditch GSM and go with UMTS only, you can support far more customers in the same space.

    Many newer handsets already preemtively support UMTS 900Mhz e.g. most new smart phones.

    Also, because UMTS is part of the GSM family of standards, the switch off and cut over to exclusively 3G networks will be seamless. Most users won't even notice, unless they've very old handsets.

    I sincerely hope that this power company has easily swappable out modules or has some plan to deal with the cut over to 3G/4G wireless.

    The typical lifespan of an electricity or gas meter is something like 60 years, where as the typical lifespan of a mobile phone is more like 2 years. So, mobile network providers really have no particular interest in supporting legacy devices.

    If you're a power utility with millions of installed devices depending on an old, soon to be killed-off data transmission system, you could be left high and dry with millions of meters and no way of reading them far sooner than you might imagine!

    Device control....

    There is (IMO) a difference between "controlling" a device, and turning it on/off....

    If my fridge/freezer is disconnected from the mains supply (manually or via powercut) I have to reset it's temperature controls. By default, it doesn't start in "Eco" mode. Thus if someone/something COULD actually turn it off, I'd lose money if I didn't notice....(luckily it sits there flashing at me until I do something about it).

    As it is, I'm on Economy 7, and have AA+ graded appliances - including a dishwasher and (imminently, a new) washing machine which have delay start, so I can have them run in the night, when it's cheaper for me, and probably when there is less demand.

    The key for me is that *I* control what does what.

    The other thing, is that BG have also just UPPED my (electricity) direct debit, despite their own website telling me my current usage is 50% LESS than the same period last year, and my being in credit...I may, imminently, be voting with my feet.

    Smart meters..

    If the utility companies want these fitted that desperately, then you can pretty much garuntee that the benefits are more or less one-sided, in their favour.

    Lets be sensible about them though. Can they control individual appliances? Not unless they AND the appliance are fitted with some form of control system (X10 perhaps?). It'd be entirely impractical to "control the socket", as you can plug anything into any socket. Any control circuitry would need to be on the appliance itself.

    When they start fitting smart meters AND x10 control circuitry to my appliances, then I shall worry about them controling individial devices.

    What they will probably be able to do, is monitor the power consumption, and reduce the amount of power being passed to the distribution board (even turning it off entirely). That is scary enough imho, but lets not get carried away here.

      > The electricity companies don't want this any more than you do.

      bullshit! the power companies have all sorts of wet dreams about smart metering. lavish bonuses and fat profit margins depend on this. smart meters give the power companies a free and never ending licence to print money and royally fuck over their customers. best of all, somebody else pays for deploying and running it.

      you couldn't be more wrong to claim the utility companies don't want smart meters.

      the main reason power companies want smart meters is because it gives them more ways to fuck their customers and rip them off. for example, changing prices in near real-time. [want to bet what happens to the cost of boiling the kettle in the ad break for the cup final or turning on the heating when it's cold?] they will be able to cut you off at will and do that from their office: no need to send round a guy in a van.

      the utillity companies won't be paying for these meters either. their customers will: you and me. so the power companies have no incentive to keep operating and capital costs down. and when they fuck it all up, we'll have to pay again for the next release.

      btw there will be another generation of smart meters real soon now to support the intelligent grid. we'll have to pay for them too. it would of course be better to deploy these meters now, but british gas has other ideas.

    Smart devices not meters

    You don't need smart meters to signal other devices in the home which may be capable of suspending when the grid is experiencing high demand, a smart device can sense this itself by looking for the frequency of the mains supply dropping.

    1. M Gale


      There's a lot of expensive equipment goes into making sure the frequency of AC doesn't change or, more importantly, go out of phase between different bits of the grid. If that happened, "kaboom" would be an understatement. You'd see engineers having to go out and replace every fuse or reset every breaker from your supply up to the power station and everywhere between.

      Voltage perhaps, but even that isn't an indicator of demand when you consider just how big the grid is, how many interconnecting parts it has and how many generators are all feeding into the system at once (again, may I add, having to be locked in sync so you don't end up with massive beat frequency oscillations and other such loveliness that can literally rip a rather large generator's rotor off its bearings if the fuses don't blow first).

      Anyway, I'm not so concerned with Smart Meters, and more concerned with recent legislation that makes it illegal for you to so much as extend a ring or add a spur, yet perfectly legal to wire an entire garage extension into the house, so long as you do it via a plug. What's with that? And how does anybody know you fitted things before or after the law came into force?

        There is a lot of equipment to make sure the frequency stays within a tight range, but it's obvious to see with any decent DVM the frequency changing by a couple of tenths of a percent, particularly when high demand kicks in during an advert break in a soap. Equipment can easily detect the frequency starting to drop and suspend themselves for a few minutes.

    The aim of these meters is to be able to price power in real-time, a bit like the way that parking meters in the center of Los Angeles vary their tariff depending on how many people are trying to park. ("Yield management" is a polite term for this sort of thing.)

    Couldn't they make electricity cheaper so that there's no need to faff around with smart meters? Has nobody thought of that?

      Tomorrow's World

      The reason smart meters will be required is to cope with a future of energy shortage. When we no longer generate enough leccy to supply our needs we will need the ability to 'manage' overall usage to make the blackouts a safer shade of brown. Being able to make the best profit out of soaring leccy prices is going to be something of a bonus for the leccy companies, of course.

      Personally I'm still waiting for the unlimited 'need to to even meter' free electricity we were promised on 'Tomorrow's World' all those years ago.

    BG or rather Scottish Gas (as it is north of the border) have already begun rolling out Smart Meters. Aside from the installer failing to inform BG of the previous electricity meter reading & BG then cocking up billing, everything went fine.

    Both gas and electricity are smart metered. It's been a god send for switching off the immersion heater when the flatmate forgets for the nth time (BIG red light on the box in the living room).

    The biggest boons for the energy companies will be (initially at least) not having to pay meter readers. There's no point complaining about this now either as it's a government sponsored program and it's in place. All homes will eventually go to smart meters (so I was told by the installer).

    I've had one for years

    Here in New Zealand I've had such a smart meter for 2 1/2 years. At present it's only reporting one reading a day at 4 PP, via Vodafone. I don't know whether it's 2G or 3G but I do know it's got a microsim like an iPhone 4.

    It's really quite useful to be able to go to the web site and see what usage has been:

    The main reason, for me, for getting the smart meter was so that I could get access to cheaper night rates for electricity. If you have separate metering in the day and at night (11 pm - 7 am in this case) then the day rate is the same as for people with a single meter, and the night rate is considerably cheaper (about 25% - 35%, depending on time of year).

    I've been able to make some changes that have meant this winter I've used around 45% night and 55% day, while in the autumn (and it should be now again in spring) it was 60% night and 40% day.

    That's a considerable saving.

        My stance is this, as im on a pre paid meter, i have to pay up front for my leccy, as i also dont give a flying fuck about polar bears, if i want to burn of kilowatts of power, i will do.

        Its simply more nanny state pandering all for the cause of "climate change".

        I have no kids, when i die thats it....Why should i care what happens in 100 years time.

          Does your DECT or CB radio broadcast on 1.8Ghz or 900Mhz? If it does, you need to get it repaired as you're in a dangerous legal position.

          my understanings is that its illegal to broadcast on licensed frequencies without the appriate permits and/or frequency owners position. Your jammer fits here.

          Don't like smart meters all you like - but in effect you're setting up a pirate radio station to protest them.

    It happened here more than a year ago .....

    And not a bad thing, as it (in theory) removes the need for being physically present at the unspecified time a meter reader may arrive.

    With typical British Gas efficiency, of course, they continued to send meter readers for some time afterwards :-).

    Should solve the problem for the holiday cottage, if it ever reaches there. Meter there hasn't been read by a meter reader for about thirty years!
