Underground cables between Nailsea and Portishead

Our contractor, Murphy, has finished installing the new underground cables between the west end of Nailsea and Portishead substation.

Installing the cables through the streets in the west end of Nailsea was completed in March, and the final rural sections were finished in April. We know this work caused local disruption and we are sorry for the inconvenience caused during the last year. Together with Murphy, we thank the communities along the route for their patience and understanding throughout this work.


The cables will be energised by July and reinstatement is set to be complete by September 2021. Remaining work includes a two week road closure on Washing Pound Lane, Tickenham to remove the temporary entrance. Advance notice signs and traffic diversions will be clearly marked beforehand. We publish timings for our roadworks and traffic management along with maps showing diversion routes for temporary road closures.
