£80m investment this year to modernise the North West gas network

• Details of 2024-25 North West gas mains upgrade programme (see table below)
• £80m investment will modernise the underground gas network that heats millions of homes
• Boost to the gas network used by more than 83 per cent of North West homes, and making it greener
• 420km of pipes to be upgraded this year (2024-25) and work secured for 600 engineers

Details of the 2024-25 programme to upgrade the North West’s gas mains – some of which were installed over 100 years ago – are published today.

Cadent, which manages the region’s gas network, will modernise around 420,000 metres of its North West pipeline over the 12 months to 31st March 2025.

This is the same straight-line distance as Liverpool to Aberdeen. It is also the same length as around 4,000 football pitches, and the same height as more than 2,600 Blackpool Towers.

The £80m investment will be delivered by 600 skilled gas engineers.

They will be upgrading vital pipes to plastic to ensure a long-term safe network, as well as remain on track to replace fossil gas with greener alternatives, such as biomethane and hydrogen.

This change is essential to achieve local plans for meeting energy demands in ways that better protect the planet.

As part of its commitment to keeping customers safe and warm, every year Cadent replaces around 1.5 per cent of its 34,000km North West underground distribution system. These are mostly ageing metallic mains nearing the end of their safe operating lives.

The work is part of a bigger 30-year engineering programme, which is happening across the UK and is due to finish in 2032.

Why it's so important to do this

“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 Head of Investment Planning Office (North West) Mark Syers, who leads the team delivering 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.

Where the work is taking place

By distance, the ‘top five’ workload areas for 2024-25 are: Wirral (45,793 metres), Manchester (24,697), Liverpool (24,287 metres), Sefton (21,656 metres), and Wigan (20,368 metres). You will find the figures for each of the North West’s local authority areas in the table below.

When the work will happen

Cadent works with the local highways authorities to agree the best and least disruptive timings to carry out these essential upgrades.

Once start dates have been confirmed, letters are sent to properties impacted ahead of the work starting and Cadent also works to inform the local area through partners and social media.

Part of the programme also involves replacing individual ‘service’ pipes of tens of thousands of properties at no extra cost for customers. Cadent makes all the arrangements and gives advance notice of when work will happen.

Gas remains on throughout, 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 to the new main. Customer teams are available to answer any questions.

If you smell gas

If you smell gas always ring the national gas emergency service immediately, day or night, on 0800 111 999*. Do not delay, or assume it is related to works taking place in your area. It may not be and must be checked.

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 current five-year Ofgem-regulated period. 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. It is set to be introduced at volume in the North West soon, through projects like HyNet (covering large areas of the North West and North Wales), as well as plans advancing in Barrow-in-Furness and Trafford Park
