Broadband Speed Test

If you suspect your broadband connection isn’t as fast as it should be, it’s probably time to check your internet speed. Our broadband speed test allows you to compare your connection against different providers in your area. Enter your details below and see how your speed compares to the average speed in your area.

How does our broadband speed test work?

Start by making sure you’re connected to the WiFi network you want to test and enter your postcode. Select whether you want to test a home, or work connection, then find your current provider from the drop-down list and hit the ‘Test my broadband’ button.

You may find that your broadband speed is slower than you expected, or that faster speeds are available in your area. Your results compare connection speeds to your neighbours’ average speeds, and set out your options if you’d like to switch providers.

Frequently asked questions

What happens during the broadband speed test?

First, a signal is sent to a test server and back to your device. The time your device takes to respond is measured. Then the server sends chunks of test data to your device and measures the speed at which it is transferred. To measure upload speed, a similar thing is done in reverse, with data sent back to the test server. This is done multiple times, to test the full capacity of your connection and to give the most accurate reading possible. Transfer time is measured in milliseconds to give us a measurement of your upload and download speeds for your results.

Are broadband speed tests accurate?

A broadband speed test only provides a snapshot of your internet connection at the time you test it. For thorough results, try running a test a number of times, including during peak (between 8pm and 10pm) and off-peak hours across the same week. It’s useful to do this because broadband speed can depend on several factors, including:

  • The number of people using broadband in your household
  • The number of people using broadband in your area
  • Whether the network uses fibre optic cables or copper wire telephone lines (fibre optic networks tend to be much faster).
  • How near or far your house is to the telephone exchange may also make a difference

Results over WiFi are slower than those with a wired or ethernet connection, so make sure you’re close to your router, ideally within 10 metres, before starting a connection speed test.

Follow these steps to make sure you get the most accurate results possible:

  • Stop downloads on all devices that use your WiFi network – remember to stop them on mobiles and TV services too
  • If possible, turn off all devices using the WiFi network and any other electric devices that could affect the signal strength
  • Make sure all cables to your router are properly connected
  • Make sure there are no large objects between your device and the wireless router

Why should you check your broadband speed?

It’s important to check your internet speed to see if you’re getting the best value for your money and the right broadband for your needs. Your internet service provider may be delivering slower speeds than promised, or you may find that faster speeds are out there to suit your streaming and browsing needs. Our results will let you know about the options available in your neighbourhood.

What should I do if I’m not getting the broadband speed I was promised?

Not getting the broadband speed you want can be a good reason to switch providers. But what if you’re still under contract?

If your broadband contract started after 1 March 2019, and your service provider has opted in to Ofcom’s Voluntary Codes of Practice on Broadband Speed, you can complain to your provider if speeds fall short of their promised speed. If the problem persists after 30 days, you can walk away from your contract, penalty-free.

For contracts starting before 1 March 2019, or those with providers who haven’t opted into the code of practice, you can still complain to the provider. And if they don’t sort out the problem, you can contact the ombudsman.
