Start date: 8 January 2024

Duration: Approximately 15 weeks

Project manager: Jack Deaney

Local delivery partner: Murray Utilities Ltd.


Project overview

We are upgrading the gas pipes along St Martins Lane to The Mall to ensure you continue to receive a reliable gas supply for many more years to come. Our aim is to replace all the metallic pipes with longer lasting plastic pipes. This means that we will need to excavate holes in the ground to access the gas pipes in order to inspect and replace them.

Due to the nature of the work involved, we have planned to deliver it in two phases to maximise efficiency and minimise disruption.

Horse Guards Road

08/01 - 31/03/2024

Phase 1

15/01 - 27/04/2024

St Martins Lane and St Martins Place

Phase 2 

17/02 - 27/04/2024

Project updates

Work paused whilst the London Winter 2024 took place over the weekend. Since then, the team has re-dug the excavation on St Martin’s Place / the junction of Duncannon Street.

A new section of pipe will be inserted from outside the Coliseum Theatre, St Martin’s Lane, across the top of Trafalgar Square and along to Canada House.

Work on The Mall in front of the Admiralty Arch is also ongoing.

An excavation has been dug outside Canada House in Trafalgar Square / Junction of Cockspur Street ready for inserting a new section of pipe and the installation of a valve.

On Horse Guards Road, the footpath and verge have been backfilled and reinstated with the exception of a small section of pathway.


The work area at Horse Guards Parade has now also been backfilled and reinstated.
