Who supplies broadband at your address?

Ofcom's data shows the speeds your home can get, but not which companies sell them. Most UK homes are on Openreach, and many also have a second network such as Virgin Media or a full fibre network. Check the networks below to see which reach your door — then every provider using those networks is an option for you.

The speed your router gets depends on the network reaching your home, not just the package you pick.

What the speed bands mean

Standard (under 30Mbps) usually means copper phone lines all the way to your home. It's fine for browsing and HD streaming for one or two people.

Superfast (30–300Mbps) is usually fibre to the street cabinet, then copper to your home. It suits most families.

Ultrafast (300Mbps and above) usually means full fibre to your home or Virgin Media's cable network. Gigabit-capable lines reach 1,000Mbps or more — handy for big households, 4K streaming and home working.

Not sure what speed you need?
Most homes don't need the fastest line. Our what speed do I need? tool suggests a speed from what your household does online.

Where these results come from

Results come live from Ofcom's Connected Nations broadband data, the same source as Ofcom's own broadband checker. Ofcom gathers coverage information from the networks and predicts the top download and upload speeds for each address. It is updated a few times a year, so a newly installed network may not show yet.

Your postcode is sent once to Ofcom to get your results. It isn't saved, added to the page address or shared with analytics.

Broadband postcode checker questions

Is the broadband postcode checker free?

Yes. It's free to use, there's nothing to sign up for, and we don't save the postcodes you check.

Where do the speeds come from?

From Ofcom, the UK communications regulator. Ofcom collects coverage data from the broadband networks and predicts the fastest download and upload speeds each address can get.

Does it show which providers I can get?

No. Ofcom's data shows what speeds are available, not which companies sell them. Use the network checkers on this page to see which networks reach your home, then compare deals from providers on those networks.

What do standard, superfast and ultrafast mean?

Ofcom calls under 30Mbps standard broadband, 30 to 300Mbps superfast and 300Mbps or more ultrafast. Gigabit-capable means up to 1,000Mbps (1Gbps) or more.

Why is my address missing?

Ofcom's list is based on Ordnance Survey addresses and is updated a few times a year, so very new homes can take a while to appear. Try a neighbour's address or check with the networks directly.

Will I get the speed shown?

It's the top speed predicted from any provider. Your actual speed depends on the package you buy, the wiring in your home and your Wi-Fi. Ask a provider for its minimum guaranteed speed before you sign up.
