We moved to sky in an attempt to save some money. Originally our line rental was with BT and our internet provided by Zen. Other than the price the prior services were excellent with d/l speeds of ~17mbs, but monthly cost was ~£50. We had a few teething issues transfering to sky during their application process on their website due to a technical issue with their server, but this was quickly and efficiently resolved by their customer support team. Sky CS kept us fully updated on the transfer status and expected change over dates etc. Our only concern was they were prediction a d/l speed of 4-12 mbs, with a minimum of 3.8mb, on what was deemed to be a 14mbs max setup. On connection day everything went fine, and sky phoned the next day to confirm there were no issues. Line training was conducted for the first 10 days, with line speeds starting @ 4mb and finishing at 16mbs. Very impressed overall. 16mbs lines speeds with no drop outs at £19 per month inc line rental and anytime free calls. However from experience, the speed a property can achieve is generally due to the line quality and distance from the exchange - luckily ours is good and as such works seamlessly on sky
