About Broadband in Chalk
Chalk is in Gravesham. Full fibre broadband is available here, with typical download speeds of around 887 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 Chalk?
Chalk is well served by full fibre infrastructure, with speeds averaging around 887 Mbps via Openreach's FTTP network. That puts the village comfortably ahead of the national picture: as of Spring 2026, 82% of UK premises can access full fibre and 89% can access a gigabit-capable connection, according to Ofcom's Connected Nations data.
No specific rollout announcements for Chalk or the wider Gravesham area have been published by ISPreview or Openreach at the time of writing. Gravesham sits within commuter distance of the Thames Estuary corridor, an area where Openreach has been steadily upgrading exchanges as part of its £15 billion national FTTP programme targeting 25 million UK premises by end of 2026. Where full fibre is already live at these speeds, ISPs including BT, Sky, EE, Vodafone and Plusnet all offer retail packages over the Openreach network.
There are no major alternative network (altnet) operators currently confirmed as active in the DA12 postcode area. Gravesham's suburban and semi-rural mix means the primary infrastructure here is Openreach rather than a CityFibre or similar build.
PSTN copper switch-off: Openreach's analogue telephone network closes in January 2027. If you or anyone in your household still uses a traditional landline phone plugged directly into a master socket, you will need to switch to a digital voice service before that date. Most ISPs are now migrating customers automatically when they take a new broadband contract, but it is worth confirming with your provider if you are unsure.
