Broadband Speeds

We constantly monitor our broadband speeds to ensure our estimates are up to date and as accurate as possible.

Our advertised speeds are based on the estimated speed that is available to at least 50% of our customers at peak times (8pm-10pm).

Due to the nature of internet access services provided over mobile networks and geographical, topographical, built-environment and other factors affecting the variability of data speeds, the above estimated speeds are not guaranteed and may not be available at all locations and within all environments.

The upload and download speeds achieved by Three customers may vary due to a number of factors. These factors are outlined in our terms and conditions.

Sometimes we may need to manage internet traffic across our network to deal with exceptional or temporary congestion. For more information please visit:

To get the best possible speed, it is important that your hub is correctly set up. Step by step instructions can be found in our user guide and will help you achieve the best speeds.
