I ditched Sky last year due to the non stop price hikes that saw a 40Mb fibre (+phone) being priced at £46.99... and went to Virgin who offered 100Mb + Phone for £32... what a mistake that was. My average since Nov was less than 20Mb and I actually got one of their staff to admit that their network couldn't handle the traffic.
I got out of that contract with some refunds and so forth and went over to Vodafone... f'kin halfwits lied through their teeth about not being able to transfer my BT originated number from Virgin (they never even tried) and I cancelled that within a few weeks and have been refunded everything paid... so almost 4 weeks of internet for free and a phone line that was never used as Virgin kept my line/number open waiting for the number port... which costs me line rental.
I got so fed up with crapp companies that I bit the bullet and went with Zen... it's pricey at £50 a month for phone/full fibre and free calls 24/7... But it's been a hassle free journey so far. Line active within 2 days or ordering, internet within 7 days and so far getting 62Mb on a 77Mb line with more tweaking to be done (I know it can support 69Mb as I had that via Vodafone).
I also have to say that I'm impressed with the supplied router too... Far better than anything supplied by Sky/Virgin/Vodafone.
The moral of this story.... pay peanuts, get shat on by monkeys.
Biting the hand that feeds IT
