How to check full fibre at your address
Which Altnet shows which altnets list your town. Street-level availability still needs each provider’s own checker — and Ofcom’s free tool for technology labels.
1. Find which altnets list your town

3. Use Ofcom’s free checker
Ofcom’s checker reports technology and predicted speeds for your location. It does not pick a retail brand for you. Start at checker.ofcom.org.uk (opens in a new tab).
4. Read the labels
“Gigabit-capable” is not the same as “full fibre”. Neighbours can see different results when a network stops at a cabinet, a block, or a plot. If a provider lists your town but declines your address, trust the address check.
