About Broadband in Blackwood
Blackwood 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 Blackwood?
Blackwood is well served by full fibre broadband. Openreach's FTTP network covers the vast majority of premises in the area, with typical speeds reaching around 883 Mbps, making it one of the better-connected towns in the South Wales Valleys.
Wales as a whole is outperforming the UK national average on fibre uptake. Openreach's FTTP network now passes more than 1.25 million premises across Wales, representing over 81% of the country, up from 1 million at the end of 2024, according to ISPreview (June 2026). Take-up in Wales is approaching 50% of those passed, compared to 38% across the UK as a whole. When other providers are included, total full fibre coverage across Wales reaches around 86%.
Nationally, gigabit-capable coverage stands at around 89% and FTTP availability at roughly 82%, so Blackwood and the wider Caerphilly county borough are broadly in line with the UK picture, though uptake locally remains lower than Openreach's Wales-wide figure suggests it could be.
On the altnet front, Ogi (formerly Spectrum Internet) operates a full fibre network across South and West Wales, including parts of the southern Valleys. TFW Fibre (TfW Ffeibr), a Welsh Government initiative, has built a full fibre network alongside the Core Valley Lines railway and extended it into Cardiff as of April 2026, with Blackwood sitting on the Rhymney Valley line corridor. ISP availability on TFW Fibre's network is still developing, but it adds a further spine of connectivity to the region.
BT's copper PSTN network is being switched off in January 2027. Any remaining ADSL or FTTC connections in Blackwood will need to migrate to a full fibre or cable service before that date, making now a sensible time to upgrade if you haven't already.
