Broadband coverage checker

Q: How do I check broadband speeds for a UK postcode?

Enter the full UK postcode and submit the form. The tool returns Ofcom Connected Nations predicted download and upload speeds for premises in that postcode, plus ultrafast and full fibre availability flags.

Q: Is this a live broadband speed test?

No. Results are predicted coverage from Ofcom Connected Nations open data for the postcode, not a live speed test from your connection. Actual speeds depend on the provider, package and network conditions.

Q: What do ultrafast and full fibre mean?

Ultrafast generally means download speeds of 300 Mbps or more. Full fibre (FTTP) means fibre to the premises rather than older copper last-mile technologies. Availability varies by address even within the same postcode.

Q: Why check broadband before buying a property?

Working from home, streaming and smart devices all depend on decent broadband. Checking Ofcom predicted speeds and fibre availability helps you avoid surprises before you exchange contracts or sign a tenancy.

Check predicted download and upload speeds, ultrafast and full-fibre availability for a UK postcode — from dial-up era copper to modern fibre and satellite options in the data.
