We’re working on a 30-year programme to upgrade our gas network. We’re replacing old metal pipes with new plastic pipe to ensure homes and businesses in the south of England and across Scotland continue to receive a safe and reliable gas 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.
