  • Details of 2022/23 NW gas mains upgrade programme, by local authority area
  • £70m investment, 450km of pipes upgraded, work secured for 600 engineers
  • Modernising the underground gas network that helps heat millions of homes
  • Helping get it ready for hydrogen and building a greener energy future
  • Over a five-year period, £800m will be invested in the North West region
 
Details of the 2022/23 programme to upgrade the North West’s oldest gas mains – some of which were installed over 100 years ago – are published today, as the region’s gas network continues at pace to prepare for a greener future.
 
Every year, Cadent replaces around 1.5 per cent its 34,000km North West underground pipe distribution system. These are mostly ageing metallic mains, which are nearing the end of their safe operating lives. It is all part of a bigger programme taking place over 30 years, and which is due to finish in 2032.
 
Upgrading to plastic ensures a long-term safe network and also means keeping everything on track to replace fossil gas with hydrogen. This switch is essential to local plans for meeting energy demands in ways that protect the planet more.
 
The mains replacement programme confirmed for the year April 2022 to March 2023 includes more than 450,000 metres of gas mains across the North West region.
 
This is the same length as more than 4,300 football pitches, or the same height at more than 2,800 Blackpool Towers. It is almost double the distance, as the crow flies, from the middle of Manchester to central London.  
 
For this year alone, that is £70m investment in the North West gas mains network, with more than 600 engineers employed to deliver the work.
 
By distance, the ‘top 5’ workload areas for 2022/23: Wirral (51,153 metres), Manchester (43,801 metres), Sefton (36,234 metres), Stockport (29,074 metres), and Liverpool (28,523 metres). You will find the figures for each of the North West’s 40 local authority areas in the table below.

Cadent works with the local highways authorities to agree the best and least disruptive timings to carry out these essential upgrades.
 
Once these start dates have been confirmed, letters are sent to properties impacted or in the vicinity of the work areas, in the weeks that lead up to work starting.
 
Part of the programme also involves replacing the individual ‘service’ pipes of 50,000 properties. This involves no extra cost for the customer. Cadent will make all the arrangements and give advance notice of when this will happen.

Why this work is so important

“More than 80 per cent of homes in the North West rely on gas for central heating and it’s our job to make sure they get it, safely and reliably, every minute of every day of the year,” said Craig Horrocks, who heads Cadent’s gas mains upgrade work in the region.
 
“As our older stock reaches the end of its safe working life, we must replace it.
 
“We’re also excited by the arrival soon of hydrogen to our networks, which is going to be essential to the North West achieving its targets to reduce carbon emissions.
 
“In most cases we’re able to insert the new pipe into the old one, a technique that reduces the time of each project and means we don’t have to dig as much.
 
“It also means an end to what often becomes increasingly-frequent visits – with associated disruption – to repair faults on the older metallic mains, as they start to show signs of age.
 
“We know it’s not ideal, but my team is determined to move as quickly as they safely can and get the work done with as little disruption as possible.”
 
Gas remains ON throughout the work, although in some cases properties that take a direct feed from the pipe being replaced will lose supply for up to 12 hours, as their building is connected in to the new main. Everyone is given advance notice of this and customer teams will be available to answer any questions.

Facts about Cadent in the North West

Cadent operates four of the UK’s eight gas distribution networks – North West England, West Midlands, Eastern England and North London. 
 
Its North West network stretches from the Lake District to Crewe and is home to 34,000km of distribution pipes (most of them underground) and hundreds of above ground installations. If placed end to end, that amount of pipes would stretch from North West England to Sydney, Australia, and back again. 
 
Around £800m will be invested in the North West’s gas network over the next five years. This will maintain safe, secure supplies to homes, hospitals, schools, offices and other sites, as well as support the UK’s targets to reduce carbon emissions. 
 
More than 83 per cent of North West households are heated by gas.
 
Backed by Cadent and many partners, the North West region is set to lead the way in a major shift from fossil gases to hydrogen. Producing only heat and water at point of use, hydrogen is key to a greener energy future and is set to be introduced at volume in the North West during the 2020s (see www.hynet.co.uk). 

Cadent

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.
