The CityFibre full fibre network enables broadband providers to offer speeds of up to 900Mb. Check the speed of your current broadband connection below.
There's more to broadband than just speed. Our speed checker measures the 'Download', 'Upload', 'Ping' and 'Jitter', find out what they mean below.
The standard measurement used by the industry today. Measured by the amount of data (megabits) downloaded per second (megabits per second or Mbps). The higher the download speed the more data you can download per second. This is important if you download large files or have multiple devices using the same connection.
Also measured in Mbps, 'upload' speed is the time it takes to transfer data from your device to another source, for example using YouTube to upload or live stream videos or sharing work files with colleagues on Teams. One of the benefits to a full fibre connection is the ability to provide symmetrical download and upload speeds.
The amount of time (in milliseconds or ms) it takes for a piece of data to be sent from your device to a server and back again. It's an important indicator of how much delay (or ‘lag’) you will experience when performing tasks online that rely on two-way data transfer, for example, online gaming, general online responsiveness of websites etc.
The delay in sending data over your broadband connection. Like ‘ping’ it is measured in milliseconds (ms), but rather than taking a one-off measurement, ‘jitter’ measures the consistency of the delay. A high ‘jitter’ rate is a good indicator of ‘congestion’ across your broadband providers connection and will result in poor video and audio experiences.
Not only is our network ultra-reliable, we also have a wide range of broadband providers for you to choose from, offering speeds up to 900Mbps.

The majority of the UK is still either using copper cabling from over 100 years ago. Or hybrid fibre, where the network builders have upgraded the connection to the exchange, but your home is still connected by copper. Our brand new network is 100% Full Fibre, meaning no disruption, high performance, end-to-end fibre. You can see the difference each option provides below...
