What broadband is available at my address?

It can change from one house to the next. Two homes on the same street can sit on different lines, so one can get full fibre while the other can’t. That’s why a postcode on its own isn’t enough: you need the check for your exact address.

Our broadband checker by postcode asks for your postcode, then your address, and shows the providers that reach your home, the speeds they sell there and what each deal costs.

Can I get full fibre?

“Fibre broadband” often means fibre to a green cabinet in the street, then the old copper phone line for the last stretch to your home. Full fibre runs all the way to your home, which is why it can reach 900 Mb and more while a copper line tops out far lower.

If full fibre has reached your address, the checker by postcode shows it with the deals that use it.

How to check your broadband speed

Run a broadband speed test on a laptop plugged into your router with a cable if you can, with nothing else streaming or downloading. Over WiFi you’re testing your WiFi as much as your line. Our test shows your download and upload speeds and compares them with the fastest line your address can get.

If your provider has signed Ofcom’s broadband speeds code, it had to give you a minimum guaranteed speed when you signed up. If your speed keeps dropping below it and they can’t fix it within 30 days, you can leave without paying an exit fee.

What is a good broadband speed?

It depends on how many people use it at once and what they’re doing. One person browsing and streaming needs far less than a family with two 4K TVs, a games console and someone on video calls at the same time.

The speed you need tool sizes your plan to the busiest hour in your home, so you don’t pay for speed you won’t use.

How to tell if your broadband is down

First check whether it’s just you. Is my broadband down? shows the live status of UK providers, checked against each provider’s own status page.

If your provider looks fine, switch your router off for a minute and back on, then try a device plugged in with a cable. Still nothing? The troubleshooter takes you through the fixes one at a time and tells you what to say when you ring your provider.

Am I paying too much for broadband?

If your contract has ended, probably. Prices often go up once the deal you signed runs out, and most providers also raise prices every April. Since January 2025 a new contract has to say any rise in pounds and pence, so you know what’s coming.

The broadband cost of living check compares your bill with the deals at your exact address over 24 months, with those April rises counted on both sides. The April price rise calculator works out your own rise. If you get Universal Credit or another benefit, the social tariff finder shows cheaper plans from £12.50 a month.

Moving home or giving up your landline

Moving doesn’t always mean taking your provider with you, and your new address may get faster broadband for less. The moving home check shows what reaches your new home before you move.

The Openreach phone network, which most homes use, switches off on 31 January 2027. The landline check tells you whether to drop your line, keep a digital one or sort a care alarm first.
