OpenReach have been fiddling with the cabinet near me, and the other end of the estate have "superfast available here" stickers on the cabinets... but I checked and I still don't have access!
Probably teaching to you to suck eggs here but I'd advise maximum pro-activity based on my own experience which went like this :-
2015 onwards - registered with OpenReach (OR) to be notified when fibre available. Checked repeatedly in years to follow.
xmas eve 2019 - arrived home to find commercial premises next door getting FTTP installed. Spoke to OR engineer and it turned out that other side of street had had FTTP for a couple of months already. Checked my ISP's (Plusnet) website to see if I could upgrade - not available. So, I let it ride for a bit as clearly the roll-out was underway.
March 2020 - became more critical as working from home and, coincidentally(?), finally got a notification from OR - 'FTTP is now available at your postcode' - so 3-5 months later than when it actually arrived. Checked Plusnet website - still no upgrade option so let it ride another month for them to catch up.
Start of May 2020 - still no upgrade option so I phoned Plusnet who told me 'Oh, It's only FTTP and we can't do that. If you want it you'll need to switch to BT' - which I did.
August 2020 - finally got FTTP after a false start in June when engineer came out to install and discovered it hadn't been surveyed correctly and OR hadn't actually extended the fibre to the pole that feeds my house.
So a right old mess from start to finish, a lot of chasing on my part and I probably could have had it 6-9 months earlier if OR had communicated in a timely fashion.
