BT Openreach are rolling out full fibre broadband to the whole of Failand.
Check the status of your property at:
https://www.openreach.com/fibre-checker
It will say "Available now" or "Build planned between now and Dec-2026".
This will deliver speeds up to 1600Mbps via fibre all the way to your property (fibre to the premisses - FTTP).
The advantage over Gigaclear is that you can use your existing ISP or any of your choice.
However Gigaclear is much cheaper and available now to the whole of Failand (except part of Lower Failand) eg:
Gigaclear £34/month for 900 MbpsZen (when available via BT full fibre) £50/month for 910 Mpps
