Full-fibre broadband: what to check before switching
A practical UK full-fibre checklist covering availability, installation, upload speed, router setup and whole-contract cost.
Start with the shape of the decision
Full fibre removes copper from the access line, but that does not make every package or installation equal. Compare what is delivered, how it enters the home, and how the router will serve the rooms that matter.
Free checks first
- Confirm full-fibre availability at the exact address using provider or network checkers.
- Identify where the fibre terminal and router could be installed before the appointment.
- Check whether important devices can use Ethernet or modern Wi-Fi speeds.
Use your own evidence

A measured shortfall is more useful than an assumption that a faster tier will help.
