Broadband speed is the rate that information is sent (upload speed) or received (download speed) on your broadband line. Its measured in 'Mb' ('megabits per second'). Take our broadband speed test below to see how fast you can go.
Broadband usage refers to the volume of information you are allowed to use over your broadband connection each month. Usage is measured in 'GB' (gigabytes).
We're constantly investing in technology to give you faster broadband speeds – even at peak times, and we always give you the best broadband speeds possible on your line. See how fast you could go with our BT broadband speed checker.

Our unlimited broadband packages are now totally unlimited, which means that you will be able to download as much as you like, enjoy catch-up TV, streamed films and online gaming without ever being slowed down.
Some other Internet service providers put restrictions on certain types of Internet traffic or a limit on how much you can download or upload which means that at peak times of day, customers may experience slower speeds.
We don't think that's a good enough experience for BT customers so we have made all of our unlimited products 'Totally Unlimited'.
Many of our great value broadband packages come with Totally Unlimited usage, which means you can use as much data as you want.
