The full fibre upgrade is being delivered by Openreach and will reach the majority of homes and businesses in Thirsk.
Engineers have already started work in the area, with plans to reach the majority of properties.
Kasam Hussain, Openreach partnership director, said: “We’re bringing full fibre broadband to Thirsk and letting local people know what to expect.
“This is a major infrastructure upgrade, so there will be more engineering teams, equipment and vans around town, and we’re working hard to keep disruption to a minimum.”
The full fibre network is designed to deliver gigabit-capable speeds and improved reliability, with fewer faults and more consistent performance during busy periods.
The upgrade is part of Openreach’s wider goal to reach 25 million homes and businesses across the UK by the end of 2026.
Openreach’s full fibre network now reaches more than 20 million properties.
Mr Hussain said: “Wherever possible, we’ll use our existing network of ducts and poles to avoid roadworks, new street furniture and disturbance.
“But there may be places where we need to install new poles, underground ducts and fibre cables because it’s the only way to make sure households get included in the upgrade.”
Residents can register for updates and, as the build progresses, check their addresses to see when services are available from their chosen provider by visiting openreach.co.uk/ultrafastfullfibre.
The website also provides information on the benefits of upgrading to full fibre broadband as the rollout progresses.
