About Broadband in Cefn Fforest

Cefn Fforest is in Caerphilly. Full fibre broadband is available here, with typical download speeds of around 883 Mbps, well above the UK average of 69 Mbps. Most major providers cover the area, so there is a reasonable amount of competition on price.

Standard broadband runs over the copper phone network. Speeds depend on your distance from the telephone exchange and typically range from around 5 Mbps to 20 Mbps.

Superfast broadband (FTTC) uses a fibre optic cable to your street cabinet, then copper for the final stretch to your home. Most urban and suburban areas can get speeds of 35 to 80 Mbps.

Full fibre (FTTP) runs fibre optic cable all the way into your home. It is the fastest and most reliable option available, with speeds from 100 Mbps upwards.

What's Happening with Broadband in Cefn Fforest?

Cefn Fforest sits in the Caerphilly county borough, and residents here are in a strong position by national standards. Full fibre (FTTP) is available to the vast majority of homes in the village, with speeds reaching around 883 Mbps on Openreach's network. That comfortably outpaces the UK national average, where Ofcom's Spring 2026 data shows full fibre reaching 82% of premises and gigabit-capable networks covering 89%.

Wales as a whole has pushed ahead of the UK average on fibre take-up. According to Openreach, June 2026, their FTTP network now passes over 1.25 million Welsh premises, equivalent to more than 81% of the country. Crucially, take-up in Wales is approaching 50%, well above the UK-wide figure of 38%. That suggests a lot of Cefn Fforest households have already made the switch, or are at least aware full fibre is available to them.

Beyond Openreach, the Valleys corridor has attracted interest from alternative network builders. TfW Ffeibr (TFW Fibre), a Transport for Wales initiative backed by the Welsh Government, has been extending its railway-based full fibre network along the Core Valley Lines and into the Cardiff area as of April 2026. Ogi, the South and West Wales altnet backed by Infracapital, also operates in the region, though its primary footprint sits further west. Coverage at your exact postcode will vary, so it is worth checking.

One deadline all Cefn Fforest households should be aware of: Openreach is closing the old copper phone network (PSTN) in January 2027. If you still use a landline on the analogue network or have a broadband service that runs over copper, you will need to move to a digital alternative before then.
