Brsk has begun work in Salford to enable 25,000 homes and businesses in the city to access full fibre broadband.
Openreach has named the 12 locations next to benefit from its fibre rollout, covering a further 184k homes and businesses.
The locations are predominantly in London with areas including Bayswater, Chiswick, Finchley, Holborn, Kensington Gardens, South Kensington, Leagrave, Pimlico, Skyport, Stratford and Wembley, as well as the village of Healing in East Lincolnshire.
Openreach has also updated its website to give more information about where and when the build will start in each exchange location.
CEO Clive Selley said: “We want our plans to be as clear and comprehensive as possible, so we’ve adjusted our published build plans to hopefully make them easier to understand."
Openreach will update the build information a minimum of every three months to adjust the timings of any areas that have moved back or been brought forward.
