We’ve developed a project to upgrade approximately 1700 metres of ageing metal gas pipes from the junction of Maidenhead Road to the junction of School Lane, including Terry’s Lane.
Some of our gas network is over 80-100 years old and over the years there have been multiple repairs, resulting in extensive traffic management. This project will eliminate the need for recurrent repairs and also enhance the reliability of our gas network to ensure we keep you safe, warm and connected.
To carry out our works safely and access our pipes, we’re carrying out these works in a number of phases with different traffic management requirements, which include road closures and temporary traffic lights.
Road closure on The Pound from the junction of Maidenhead Road to the junction of Terry’s Lane.
Junction closures on Terry’s Lane and Grange Road from The Pound.
Access will be maintained for residents, no through road or turning points.
Please follow signposted diversions via Maidenhead Road and Sutton Road.
Two-way traffic lights on The Pound from the junction of Terry’s Lane to the junction of School Lane.
Two-way traffic lights on Maidenhead Road from the junction of Station Hill to outside Appledown.
Multiway traffic lights on The Pound from the junction of Terry’s Lane to the junction of School Lane.
Road closure on Terry’s Lane from the junction of The Pound to the junction of Poundfield Lane. Access will be maintained for residents, no through road or turning points.
*Dates may vary if we encounter any engineering difficulties.
Thank you for your patience during these essential upgrades to keep you safe, warm and connected.

We’re upgrading the ageing gas pipes to tough, durable, long-lasting plastic pipes, which are expected to last over 80 years and will help reduce the likelihood of disruptive, unplanned work to repair ageing gas pipes in the future. Just as importantly, this work will ensure the network is safely carrying gas to heat your properties, provide hot water and cook your food.
If your property is on a road where we’re replacing the gas pipes, then we’ll need to turn off your gas supply for a short period of time on one or two days, starting from approximately 7.30-8.30am until approximately 8pm at night. We’ll send you a letter if this directly affects you to let you know when this will be.
If you haven’t got gas by 7:30pm, please call our customer care team on 0800 085 4478 and let them know.
If you’re registered on the Priority Service Register (PSR) or eligible to be registered, our team will offer alternative heating and cooking facilities.
We’ve notified the bus companies of our works and plans are in place for buses to follow the diversions and temporary bus stops will be arranged.
We’ll continuously review any congestion and manually change the lights accordingly to keep the traffic flowing.
We’re in contact with local schools to inform them of our works, so that school transport companies, parents and carers can plan extra time for their journeys.
This is a common question we encounter; we’ve contacted the refuse companies to advise them of our work, and we’ll work closely with them to ensure collections take place as normal on the dedicated day each week.
Our on-site teams will be working variable hours between 7am-8pm, 6 days a week. This will vary based on engineering and reinstatement activities.
There may be times when the team isn’t visible on site during the allotted hours. Although it may appear that no one is working at the site itself, they’ll be working in surrounding roads to insert pipes, make connections and to carry out testing, as well as allow for concrete curing. It is only once we are satisfied that the new pipe is safely supplying gas to customers that we can fill in the holes and tidy up.
Once the work is complete, we’ll fill in the holes and resurface the area we’ve dug up, to nationally approved highways standards. We match the colour and texture to the existing surfaces as closely as we can, but new surfaces will take time to weather.
There may be times when holes have not been filled back in. This is due to sound operational reasons. For example, the nature of our work means it’s often necessary for a hole to remain open to provide access to gas pipes in connection with gas pipes in other roads that we’re working in.
We have a commitment to fill holes and return the paths and driveways on your property back to normal within five working days of your gas going back on. If you have a path or driveway made of specialist or hard-to-source materials, such as printed concrete, this may take slightly longer.
Further information on this project can be found on this webpage.
If you have any specific questions, you can call our customer care centre on 0800 085 4478. We’re open from 8am to 8pm Monday to Friday. You can also email us any time at [email protected].

All businesses will be open as usual during our works, please follow signposted diversions for access.
We need to carry out our work during the day as we need access to properties to upgrade their gas service (that’s the smaller pipe that connects gas to their property).
When we do this, we need to turn off their gas supply temporarily, test their gas appliances and turn their gas back on.
Yes, we will maintain access to properties during road closures. If you have any access needs that we need to be aware of, please let our on-site teams know so that we can accommodate you.
We are returning to Sutton Road, Cookham to complete the next phase of works to upgrade the ageing gas pipes in the area, from 30 March to 12 April 2026 over the school Easter holidays.
Last year, we started this project but in consultation with the Royal Borough of Windsor and Maidenhead Council and Buckinghamshire Council, we agreed to complete this section of work at a later date.
There will be a complete road closure and no through access along Sutton Road from St George’s Lodge to Odney Lane past Churchgate.
Access will be maintained for all businesses and residents however, this will be via the Cookham Bridge, as these is no through access along Sutton Road during our road closure.
We will be working seven days a week to complete this work as safely and quickly as possible. We appreciate we will be working over the Easter Bank holiday weekend, we promise we won’t be doing any noisy work on Easter Sunday.
Some pavements will be closed with alternative routes in place as applicable.
Stuart Donaldson, Head of Investment Delivery explained, Over the years, there have been multiple repairs on these gas mains, resulting in extensive traffic management measures each time. These frequent repairs have significantly disrupted the road, road users and the community.
After significant discussions with the local council and highways authority, we have developed this project to upgrade the gas pipe.
We are completing this work, with agreement with the council and Highways Authority during the Easter holidays when the traffic flows are reduced.
While this project will temporarily affect the area, it is designed to eliminate the need for recurrent repairs, thereby reducing traffic congestion and disruption.
Ultimately, this proactive approach will enhance the reliability of our gas network and ensure that we can keep our customers safe and warm long into the future.
