Test your broadband speed ›

This broadband speed test lets you check the upload and download speeds of your internet connection.

For the most reliable test result, use an Ethernet cable to connect to your router. This takes your wifi performance out of the equation.

Remember - your broadband speed will vary depending on things like how far you are from our equipment and how many other people are using the internet at the same time. So the speed of your plan is the maximum possible speed - not a guaranteed speed.

The data transfer rate used in speed tests is normally megabits per second. This is shown as Mbit/s or Mbps. You want to be as close to the theoretical maximum that you can achieve for your type of broadband.

Download The maximum speed (megabits per second) online data can be sent to your computer.
Upload The maximum speed (megabits per second) data from your computer can be sent to the network.
Latency The amount of time (miliseconds) it takes a unit of data to travel from source to destination.
Packet Loss The percentage of units of data that are lost whilst travelling from source to destination.
Your IP The address used to send data between your computer and the network.
ADSL Asymmetric Digital Subscriber Line, which has a theoretical maximum speed of 24Mbps
VDSL Very high speed Digital Subscriber Line, which has a theoretical maximum speed of 70Mbps over Chorus lines
