The UK is undergoing a major digital upgrade as full‑fibre broadband rapidly replaces ageing copper networks. Openreach aims to reach 25 million premises by 2026, bringing faster, more reliable connectivity to businesses nationwide.
The current state of full‑fibre in the UK
Coverage is expanding quickly:
- More than 21.75 million premises now have Openreach FTTP access (65% of the UK).
- Nearly 80% of UK homes and offices now have full‑fibre availability.
- Full‑fibre could reach up to 29 million properties by late 2027 with the right support.
The copper switch‑off
As fibre availability grows, copper services such as ADSL and FTTC are being phased out. Once an exchange hits 75% fibre coverage, it enters “stop‑sell”, meaning copper services can no longer be ordered. This supports the nationwide PSTN switch‑off due to complete in 2027, when all services transition to digital IP‑based connections.
Why full‑fibre matters for UK Businesses
1. Greater productivity
Ofcom highlights that full‑fibre will significantly boost productivity across the UK economy, supporting both digital‑first organisations and traditional industries.

From cloud services to VoIP, payment systems and remote working, full‑fibre provides a future‑proof foundation that copper cannot match.
