Geographic availability

Full fibre services on the CityFibre network are subject to geographic availability. See if your property is already connected on our availability checker at cityfibre.com.

In certain instances, additional qualifiers and processes can be required to connect your home to the CityFibre network due to architectural, technical, health and safety, engineering or legal elements involved. If you have been told that you are ready to be connected but are experiencing difficulties, please get in touch.

Reliability

The CityFibre network is 100% fibre-optic, from our exchanges directly into your home, and delivers connections 5x more reliable than the ones that rely on copper cables to connect properties to the street cabinets.

Speed

The UK’s average download speed for fibre-to-the-cabinet broadband (FTTC), which uses copper cables to reach your home, is 58Mbps. CityFibre’s network delivers full fibre broadband speeds of up to 5.5 Gbps, which is up to 95 times faster than average FTTC broadband. This is calculated by dividing this speed (5500) by the average FTTC speed (58).​

The UK's average broadband speed (including ADSL, FTTC, Cable and FTTP) is 223 Mbps download and 18.4Mbps upload. CityFibre’s network delivers full fibre broadband speeds of up to 5.5 Gbps upload and download, this is up to 24 times faster for download speeds.
