Have had several Internet providers. Talktalk useless ,smaller companies not too bad. BT are the only company I have used twice. First time initial speeds seemed good but as the contract carried on it just seemed to get slower and slower with others in the house also noticing this. Switched to Sky and for the contract the speed always seemed decent, 18 months. After Sky would not give me a deal which they were offering to new customers and expected me to pay silly prices for their service, I went back to BT. Exactly the same as before initial speeds were good , but over time it just got slower and slower. So going back now to Sky. If they keep the speeds the same through the contract I may just stay with them this time. Are BT manipulating the speeds for their customers? I don't know but having had 2 contracts with them now, it certainly looks like it.
