About Broadband in Castle
Castle is in Lichfield. Full fibre broadband is available here, with typical download speeds of around 884 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 Castle?
Castle, in the heart of Lichfield, is well served by Openreach's full fibre (FTTP) network, with speeds reaching around 884 Mbps available to homes here. That puts Castle comfortably ahead of the national picture: as of Spring 2026, roughly 82% of UK premises have access to FTTP and 89% can access a gigabit-capable connection. Castle residents who have taken up full fibre are already benefiting from one of the fastest residential broadband technologies available in the country.
No ISPreview or Openreach announcements specific to Castle or the wider Lichfield district were found at the time of writing. The area's coverage appears to have been delivered as part of Openreach's ongoing national commercial rollout rather than a distinct funded or publicly announced local project. Providers selling over the Openreach network here include BT, Sky, EE, Vodafone, Plusnet and a range of smaller ISPs such as Aquiss, which recently launched 1.2 Gbps and 1.8 Gbps tiers via Openreach (ISPreview, June 2026).
One change that will affect every property in Castle regardless of broadband speed is the PSTN copper phone switch-off, due in January 2027. Openreach has confirmed the analogue phone network will close, and around 1.9 million UK lines have yet to migrate to a digital alternative. If you or anyone in your household uses a traditional landline, a VoIP or digital voice service needs to be in place before that deadline.
Altnet providers have concentrated their independent full fibre builds mainly in larger urban centres and new-build developments, so the Lichfield area is currently served primarily through Openreach. This means a wide choice of ISPs is available, but typically all running over the same underlying network.
