We are replacing ageing metal pipes with modern plastic infrastructure. This programme is designed to ensure that homes and businesses across the south of England and Scotland continue to receive a safe gas supply. It will also support the long-term reliability of that supply for years to come.
Here’s some of our major upgrade projects. You can find details of all our other upgrade projects, as well as emergency work, on the Roadworks in your area page.
