Broadband speeds made simple

Your speed estimates include three different things: your download speed range, your Stay Fast Guarantee and your upload speed range.

It’s important to know that the speed ranges we show are estimates. Your actual speed depends on your location, line, home wiring, Wi-fi connection and time of day.

How the Stay Fast Guarantee works

You’ll get your very own Stay Fast Guarantee speed when you join with us.

We constantly check and optimise your speeds, but you can also test the download speed to your hub in My BT. If it’s slower than it should be, we’ll run checks to fix the problem and send out an engineer if needed.

If we can’t get your Stay Fast speed back to where it should be within 30 days of a problem being reported, you can claim £20.

At that point you can also leave your contract without penalty. This is because we’ve signed up to the Ofcom Voluntary Codes of Practice on Broadband Speeds.
