That's where our broadband speed test comes in. It lets you track your home internet connection to see how it measures up to the download speed you thought was guaranteed.
Keep reading to use our free broadband speed test, and to find out how you can use the results to make a complaint to your broadband provider.

How to use our broadband speed test tool
Before you make a complaint to your ISP about slow broadband, it's worth gathering enough evidence to back up your claim.
Simply click the 'Start' button below to launch the broadband speed testing tool.
We suggest you run several tests during a single week, in peak usage time (between 5pm-11pm) and during off-peak times.
- The speed test should be run on a desktop PC, all-in-one PC or laptop - results on a mobile phone or tablet may not be 100% accurate.
- For the most accurate results, you should consider connecting your PC to your router via a network cable before running the test.
Which? Recommended Broadband Providers
Are you unhappy with your current broadband provider? If so, we can tell you which broadband services are recommended by thousands of users in our latest survey. The names may surprise you but both offer decent speeds and great customer service.

Using the broadband checker to complain to your ISP
If your speeds are significantly less than you expected, your broadband provider may be in breach of contract. We suggest calling your ISP as a first step to see what it can do. Start by providing evidence of your internet speeds – it's a good idea to keep a diary of interruptions and to regularly use the speed checker tool to build up a picture of your service.
If you're not happy with your ISP's response, then follow our guide on How to complain about your broadband speed.
How to boost your download speed
As well as speaking to your provider, there are simple steps you can take to speed up your connection. Changing your router, or just moving it, can make a big difference.
