Recently gone live here in Chippenham for FTTP. Clicked the link but £39.99 offer only gives me a Fibre 300 deal and no mention of Fibre 900. I've got another 8 months on my Plusnet deal though so I think BT is the only place I can move to without penalty. More research I think.Try the “magic” link https://www.bt.com/campaign/full-fibre-240 . My address shows a discount on here but not on the general deals page.
I’ve been on Sky FTTP for a year now and it’s been fine, only issue was some sort of DNS outage a few months back but other than it it’s fine.
