What fibre broadband is available in Cardiff?

According to Ofcom’s 2024 Connected Nations Wales report⁹, the availability of fibre broadband in Cardiff is as follows:

Constituency	Part Fibre Coverage	Full Fibre Coverage
Cardiff East	99%	71%
Cardiff North	99%	84%
Cardiff South and Penarth	98%	84%
Cardiff West	99%+	71%

Whereas hybrid fibre broadband, sometimes called fibre-to-the-cabinet (FTTC), still uses copper wiring to help connect your home to the internet, full fibre only uses fibre optic cables. This not only makes connections faster but also improves performance.

However, if you can’t get full fibre broadband where you live, hybrid (also known as part fibre) remains a solid option, supporting activities like:

File downloads
Video calls
Streaming TV/music

You might find trouble supporting multiple devices with part fibre broadband.

If yours is a large family, an HMO, or you live in student accommodation, make sure you opt for broadband speeds of 100Mbps or greater where possible. This will help reduce latency when multiple people are online at the same time.
