• Upgrade projects


       Watch our short film to find out more about what to expect when we upgrade our gas network in your street

    When we work in the street, we may need to take measures that allow us to carry out the work safely while keeping the road open for pedestrians and allowing access to homes and businesses.

    For example, if a road is particularly busy or narrow, we may have to use temporary traffic lights or suspend parking. We will agree any such restrictions with the local council.

    We always provide notice in advance of planned works.

    If your home or business is supplied with gas, we will need to test and potentially replace the service pipe to the property. If we need to replace your service pipe, we will also need to disconnect your gas supply and aim to have this restored on the same day.

    This may also involve excavating outside your property, in the footpath, driveway or road. The holes and trenches will always be protected using cones, signs and barriers. We will keep the disturbance to a minimum and when we have finished the area will be reinstated.

    We’ll get in touch with you to let you know what we need to do and will arrange to visit your property on a particular date. Should we need to interrupt your gas supply, we’ll tell you before hand.

    If you’re going to be away on holiday or the date is not convenient, please tell us so that we can discuss alternatives with you. We would also welcome your help in ensuring that any elderly or disabled neighbours are aware of the work we are doing in the area.

    Sometimes our work can turn out to be more complex and difficult than originally thought, so we may need a bit more time to complete the project.

    We fully sympathise with and apologise in advance to those who will suffer inconvenience because of our work.


    Safety is at the heart of everything we do and our work to renew gas mains brings with it a commitment to keep members of the public and our staff safe at all times.

    We often use traffic management and partial road closures to allow room for manoeuvre of equipment and ensure everyone’s safety.

    The planning and execution of our roadworks adheres to the New Roads and Streetworks Act 1991 (NRSWA).

    All authorised SGN employees and contractors carry an identity card displaying the company name, their own name and a colour photograph of the individual. There is also a telephone number to call to check their identity.

    If someone calls at your door requesting access to your property, please check their details carefully and if you are not happy, please contact us on 0800 912 1700 to check. If they can not produce this identification do not allow them access to your property.

    If you smell gas at any time, call the National Gas Emergency Number on 0800 111 999, lines are open 24 hours a day, 365 days a year. All calls are recorded and may be monitored.
