Gas investigators at the ready: Motorists alerted as engineers prepare to probe suspected gas leak in Hemel Hempstead

  • Temporary closure of 15m eastbound stretch of St Albans Road off The Plough Roundabout (Magic Roundabout) to enable engineers to search for suspected gas escape
  • Signed diversion will be in place
  • Local shops and businesses will remain open as usual 
Motorists are being advised of a road closure in Hemel Hempstead as Cadent engineers deal with a complex engineering task.
A 15m eastbound stretch of St Albans Road off the Plough Roundabout (also known as the Magic Roundabout) will be temporarily closed for at least a week to enable the work to be carried out. The closure will be put in place from the early hours of Monday 8 April 2019.
The closure will enable engineers to dig down to an intermediate pressure gas main and locate and repair a suspected gas escape.
A signed diversion will be in place via Leighton Buzzard Road, Link Road, Redbourne Road, Swallowdale Lane and Maylands Avenue.
Engineers will work to locate and fix the repair as soon as possible using minimum dig technology where possible to speed things up.
Cadent is sorry for any disruption this essential repair may cause and will do all we can to complete the work as soon as possible.
This work must be done to help ensure the local community keep on enjoying safe and reliable gas supplies for cooking and heating.
Local gas supplies are not expected to be interrupted during the work and local shops and businesses will remain open as normal.
For more information on the work people can call 0845 835 1111 or email

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.
