Previous to Sky I'd been with BT for about 7 years and although I never had a problem with the serive, I did get annoyed with paying £24.95 a month for 2.5Mb/s, even more so when I switched to Sky (nothing physical changed) yet I get an increase in line speed and save over £20 a month! Have even managed to move home and Sky did a good job of it, no charge although I had to change my number and it took 2 weeks to activate the line at the new house as they had to wait for a BT Openreach engineer to do his bit first. Other than that, no complaints so far!
