Upgrading our network in south London
Our gas infrastructure underpins homes, hospitals, schools and businesses across the city. Much of it was built decades ago and, while it continues to operate safely today, some assets are reaching the end of their engineering life.
SGN is investing £30 million to upgrade 15km of our pipes in south London to ensure a safe, reliable and resilient network for millions of people who depend on it every day, while enabling the long-term transition to lower-carbon energy systems.
The five-year programme's first project will take place in the Burnell Road of Sutton. It will begin on Monday 20 July and be carried out in several phases to help minimise disruption to the local community.
Replacing our pipes in Sutton
We're preparing to start essential work to upgrade the gas network in the Burnell Road area of Sutton as part of a £30 million investment programme to replace our old, large metal mains across south London.
It follows close consultation with Sutton Council, TfL and other key stakeholders, and has been carefully sequenced as part of the wider programme to reduce disruption and impact.
- Our work will start on Monday 20 July and it's expected to last until Sunday 1 November
- Temporary traffic lights and road closures will be in place for everyone's safety
- Details about the roads affected, and a map outlining the closures, can be found below
Once this project is complete, it will mean we won't have to undertake emergency repairs at short notice. We recognise roadworks can be frustrating, but these upgrades will ensure people will be able to enjoy the benefits of a safe and reliable gas supply for many years to come.

What do the closures mean for me?
- Signed diversions will be in place for affected motorists.
- Vehicle access for residents will be maintained from one end of the closure. Our engineers and local signage will keep road users and residents informed.
- Parking bays will be suspended at times during our work. Signage will be installed in advance to notify of upcoming suspensions.
- Bus routes may be impacted. We advise residents to contact their service provider for the latest updates on changes to services/routes, timetables and bus stop locations.
- All businesses will remain open around our closure areas. Access to these commercial properties will be maintained throughout.
- We’ll work with the local council to ensure refuse collections can continue to be made with as little disruption as possible.
Why this project matters
Strengthening critical infrastructure
These upgrades will improve safety and reliability for the Sutton community
Avoids short-notice disruption
Not investing in upgrades here risks unplanned gas outages, emergency repairs and greater long-term disruption
Delivering energy sustainably
Renewing our pipes will help cut methane emissions and support the transition to renewable gases such as biomethane
