How do I check what broadband I can get at my postcode?
Who this page is for
Movers and upgraders comparing fibre availability before they commit.
Plain-English definitions
- Availability checker
- A tool that matches an address or postcode to network coverage databases held by providers or regulators.
Sensible workflow
- Use provider checkers for networks you consider.
- Read Ofcom materials on how speeds should be explained at sale.
- After install, run Pulse on Ethernet to see what you actually receive.
Compare packages when ready: BroadbandSwitch.uk, SearchSwitchSave.com, FibreSwitch.com.
Pulse measures download speed, latency, and jitter in your browser. It does not measure upload speed. For upload, use your provider’s tests or see our upload scope guide.
Compare broadband deals when your line is too small for what you do: BroadbandSwitch.uk, SearchSwitchSave.com, FibreSwitch.com.
UK rights and switching: start with Ofcom’s broadband guidance for personalised speed estimates, switching, and complaints.
Example scenario
A checker promises “gigabit to the property” but in-home Wi-Fi only hits a fraction. You wire the desk and get closer to the line potential.
FAQ
Why do two checkers disagree?
Databases and planned build stages differ. Treat checkers as estimates and confirm with the ordering process.
Why do two providers show different speeds for my postcode?
Build plans, databases, and product definitions differ. Treat figures as estimates until you order and test installed service.
Does “fibre” mean the same everywhere?
No. Marketing terms vary. Read technology details and upload as well as download.
Can availability change after I check?
Yes, as networks expand. Re-check closer to order if your project slips months ahead.
Should I rely on a neighbour’s speed?
Only as a clue. Lines to adjacent homes can still differ.
What should I do after install?
Run Pulse on Ethernet, compare to your paperwork, and keep records if speeds fall short of what you were told.
