    • Essential work in Norwich will help keep residents connected to safe and reliable gas supplies for cooking and heating
    • The scheme involves replacing 800 metres of ageing gas mains with traffic management in place throughout.
    • Work expected to be completed by May

    While the opening of the Carrow Road stadium may have been the biggest story in Norwich in 1935, it was also the year that metal gas pipes were being installed under roads in the city.

    Now, 89 years on, it is time for the gas pipes to have an upgrade to tough plastic ones which will future proof the network for many decades to come.

    Starting on Monday 16 March, engineers from Cadent – the UKs largest gas distribution network – will replace 800 metres of metallic gas pipes.

    The project is part of a £91m investment this year, which will see more than 300km of pipes upgraded in the East of England.

    The work is being carried out in phases along Southwell Road, Hall Road and Hospital Lane, while traffic management will also affect Trafalgar Street, Hughenden Road and Hatton Road.

    To ensure the safety of everyone, there will need to be a road closure in Southwell Road which will be carried out in two phases. Diversion routes will be put in place and access will remain in place for residents throughout. There will also be a requirement for multi-way traffic lights in Hall Road. Again, these will be used in two phases.

    Following consultation with Norfolk County Council, Cadent has agreed to carry out this essential work over an eight-week period.

    Eleanor Buxton, Head of Work Management at Cadent, said: The metallic pipes that are in place in this section of the network have been very well used over the past 89 years and it’s time for them to be replaced so that we can continue to deliver gas to peoples' homes 24/7, 365 days a year.

    In this part of Norwich, around 80 per cent of homes have gas central heating. Upgrading these pipelines will ensure we can continue to distribute gas safely to them, for many decades to come.

    These upgrades also have big environmental gains, as they reduce methane emissions and enable a move to more renewable gases like biomethane. This is essential for a cleaner future – the UK will need energy to come from a range of sources to meet demand and be sustainable.

    We are very conscious of the disruption works like this cause and hope people can accept this project is essential to maintain a long-term safe gas supply.

    Gas stays ON for the duration of work. The only interruption to supply will be to properties that take a direct feed from the pipes being replaced (in the immediate local area). Supply to these properties will be disconnected for a short while (it will be back on the same day it goes off), as the property gets connected into the new pipe. Advance notice will be given, and more information will be provided to these properties.

    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.
