Ipswich gas mains replacement projects help keep energy flowing for decades to come

in your area

Work has started on a major gas mains replacement programme in Ipswich running throughout 2022/23, which will help keep the energy flowing safely and reliably for at least another 80 years.

Cadent, which runs the local gas distribution network, has planned a number of projects in the town to replace ageing gas mains with new plastic pipes. Work is already taking place in several streets including Churchill Avenue and Chartwell Close.

From 27 June, three-way traffic lights will be installed on Valley Road at the junction of Westerfield roundabout, for approximately three weeks. Work will then continue towards Henley Road.

Our teams will also be replacing mains on Valley Road and Colchester Road from next week, with two-way traffic lights on Valley Road and Colchester Road for approximately 26 weeks.

Wherever possible, the new pipes will be inserted into the old gas mains which reduces the need for large excavations. However, some of the work will require trenches to be dug due to the size of the gas mains which need to be installed.

So that the work is carried out safely and efficiently, a number of road closures or lane closures will also be required, with multi-way lights also needing to be set up in some areas. Advanced notice will be given including road signs and letters to nearby residents and businesses.

Ageing gas service pipes supplying individual properties will also need to be replaced. To carry out work, engineers will need to switch off the gas supply to affected properties for approximately 12 hours. Cadent will be writing to those properties involved nearer the time.

People are reminded that they should ask to see official identification – which all Cadent employees and contractors will carry – before allowing engineers access to their property to carry out work.

Mark Briggs, Head of Investment Planning at Cadent for the East of England, said: ‘These projects will help ensure our gas network keeps the local community in Ipswich connected to safe and reliable gas supplies for decades to come.

‘We’re working closely with local authorities to deliver the projects with as little disruption as possible, helping to keep traffic moving by minimising road and lane closures as much as we can.

‘This is essential work to upgrade gas mains and keep energy flowing for at least another 80 years.’

It’s part of Cadent’s ongoing investment across the East of England Network to replace ageing metal pipes with new, more durable plastic pipes.

Cadent is the UK’s largest gas distribution network with a 200-year legacy.  We are in a unique position to build on strong foundations whilst encouraging the curiosity to think differently and the courage to embrace change.  Day to day we continue to operate, maintain and innovate the UK’s largest gas network, transporting gas safely and protecting people in an emergency.   Our skilled engineers and specialists remain committed to the communities we serve, working day and night to ensure gas reaches 11 million homes from Cumbria to North London and the Welsh Borders to East Anglia, to keep your energy flowing. 

Future of Gas: Here at Cadent we support the Government’s plans to reach Net Zero by 2050. That means we’re backing the introduction of hydrogen as a low carbon alternative to natural gas for the future. We know people love the controllability of gas and, with our network already in place, it makes sense to switch to the lower carbon alternative offered by hydrogen, which we believe can keep homes and businesses warm for generations to come.
