• Infill projects

    Line drawing representing an infill area


    An ‘infill’ is when we extend our network by laying new gas mains to a community where there’s currently no gas.

    The cost is shared by the properties within the project boundary.

    Once the project is accepted, the infill becomes 'live' for a 20-year period during which time any property connecting to the new gas main must pay the same fee as those who originally joined the project. These charging arrangements are provided for under the Gas (Connection Charges) Regulations.

    If you have any questions about infill projects, please call our Customer Service team (Mon-Fri 8.30am-6pm).
