Our speed test works in all modern browsers including the latest versions of Internet Explorer, Edge, Chrome, Firefox and Safari. No other software or applications are required.
Our speed checker measures the time taken to download random data from our servers. Data is continuously downloaded until we are confident that we have an accurate result. If we have not calculated the accurate result after 60 seconds then the test is cancelled.
Our speed test normally completes in around 20 seconds. This time is required to ensure that the test is as accurate as possible. Quicker tests are not as accurate.
We recommend that you keep your previous results so that you will know if your speed is getting faster or slower. The easiest way to do this is using the history option from our main menu as shown in the image below. You will be asked for your email address so that we can show you your results but nothing else.
Our software analyses the performance of the test in order to ensure the results we provide are a true reflection of the user experience during the test.

We will keep trying to complete a successful test for up to 60 seconds before cancelling the test. This could be due to unreliable or unstable connection between the device and the internet.
