I have been with Sky Broadband over 8 years, moving to ADSL2 with them then onto their FTTC service when it first started, which was called Fibre Pro at the time

Had faultless service, immediate upgrade to latest routers when I requested a new one, no additional charges for equipment and in all that time, the service has gone down once when a company sliced through the cables at the top of my street. Never gone down by them

I have a FTTC service which comes in at 65MB download and 19MB upload

No issues with their router boxes but ensure you renegotiate it every 12/18 months to keep the best deal. Currently paying £25 for FTTC and line rental thrown in. Needs renegotiated next February but if they offer a competitive deal I will stay. Although they are ok, I am well aware that other services use the same cabling to my home as they do and how easy it is to switch. I make that part of my negotiations and I have made them undercut advertised Plusnet offers on two occasions
