Not sure what broadband speed you need? You're not alone. Choosing the right package can feel like a guessing game, especially with so many speeds to choose from.
Our free Broadband Usage Calculator takes the guesswork out of it. Simply tell us a little about your household, and we'll recommend a speed that's a great fit for the way you use the internet.
If your broadband speeds are not running as expected, try the following quick fixes:

Broadband speed tests use different servers and methods, so the results will not always be identical. Some connect you to the nearest server, while others simulate streaming traffic or apply different measurement rules.
It’s normal to see slightly different results across speed test tools, even when testing at the same time and place. All speed tests should be treated as a useful indicator of your broadband performance in that moment, rather than an exact figure.
If you’re unhappy with your results and considering a change, see our One Touch Switch Guide. This is especially useful if you’re comparing broadband providers UK and reviewing broadband test differences before you switch broadband provider.

Wi-Fi is affected by interference from walls, distance, and other household devices. A wired Ethernet connection gives the most accurate measure of your line’s full potential. If you want the truest result from your broadband speed test, we recommend testing with a cable.

Yes, running our broadband speed test is completely free. You can test internet speed free at any time, and it only uses a very small amount of data, which only matters if you are on a capped broadband plan (a package with a monthly data allowance rather than unlimited usage) rather than unlimited broadband UK.
Our broadband speed test is designed to give a fair and reliable indication of your connection at the time you run it. Results can vary depending on your device, Wi-Fi setup, and the testing method used.
Other providers (such as Ookla, Fast.com, and Cloudflare) use different testing methods and servers. This explains why results may differ slightly, even when tests are run from the same location and IP address.
The Fusion Fibre Group test uses industry-standard techniques and is continuously refined to align with larger platforms, while remaining free, transparent, and customer-focused.
No broadband speed test is 100% exact. All results should be seen as an estimate of your performance at that moment, not a guarantee. For more details, see Ofcom’s guide to broadband speeds.

Not always. Broadband speeds are promoted as either ‘up to’ speeds or average speeds (the speed at least 50% of customers can achieve at peak times). This is a requirement set by the ASA and CAP broadband advertising guidance.
Your personal results may differ depending on your home setup and usage. For more detail on broadband speeds and how it impacts your online experience, see: What is a Good Broadband Speed?
Our broadband speed test UK is a simple internet speed checker that measures your download speed, upload speed, ping, and jitter at the time you run it. These figures show how quickly data moves to and from your device.
For more information on the key metrics to look out for and what they mean, see:
These guides will help you understand how download speed, upload speed, and internet bandwidth impact your connection and everyday broadband performance.
Advertised speeds reflect what is technically possible on your line, but your actual results may vary. Common reasons include:
If you are testing on Wi-Fi, try connecting your device directly to your router with an Ethernet cable for more accurate results.

No. The result is a snapshot of your speed at that moment. Your broadband package may include a Minimum Guaranteed Download Speed (MGALS), also known as your guaranteed broadband speed, which is the figure providers commit to delivering under the Ofcom Broadband Speeds Code of Practice. You can find this figure in your welcome documents.
If your results remain below your guaranteed broadband speed, you can also check whether full fibre is available in your area: Full Fibre Broadband in My Area: How to Check Coverage & Get Connected.
