In reply to a post by mootster:

Hi, I live in a rural area and on ADSL was getting about 3mb broadband. I was sold a fiber package by Sky for £17 a month and switched over 3 days ago but the speed is an abysmal 0.8mb download and upload 0.8mb. I called Sky who sent an engineer out today who's equipment could not even pick up a connection it's so bad. I asked Sky to go back to ADSL and they said it was not possible. I have been advised to write to ofcom and my MP.
I would like to switch back to ADSL- will this be possible? Any advice much appreciated I'm gutted. Thanks

Question? Did you get this resolved?

From Sky.com terms:

When you are selecting a Sky Broadband product to order, we will provide you with an estimate of the fastest download speed that your phone line can support. This is an estimate based on information including the length and quality of your phone line, and refers to the download speed that we believe a Sky Broadband connection could achieve between your router and the broadband equipment in the local telephone exchange

Did you sign up on-line or via the phone? You can Cancel your Sky Fibre service if it does not achieve the estimates, once you have at least allowed Sky to resolve the issue.

Just a bit of help.
