Re: No estimated bills in my house.
I use my smartphone to take a photo of my meter readings .. it's fast to do, I can type the numbers in to the website in the GCH-warmth of my house and I have an audit log of them all, complete with datestamp, GPS location and MPRN/serial number.
They are very useful to email over to the energy billing company (I refuse to call them suppliers) when you need to question the bill.
