Multi-million-pound upgrade

Engineers from UK Power Networks have been finishing off a £16.2 million upgrade to an electricity substation hidden beneath the gardens and iconic ticket office at the London landmark of Leicester Square


The underground substation was opened by Her Majesty the Queen in 1991 and after regularly maintaining the infrastructure for three decades, UK Power Networks is replacing key equipment with cleaner, greener models so it’s fit to support the local economy for years to come.

The third of three large transformers – devices which step down the power voltage so electricity can be safely delivered to local properties – is being installed to meet greater energy demand in the area.

Commenting on the scheme, project manager Jason Gunning said: “We started this project in November 2020 and used the unique opportunity during lockdown to press on with the work, and it’s been very important to us to engage in discussions with people who may have been impacted by our work, to agree the best working methods for this busy site. We will continue to work safely to encourage innovation, boost resilience and create a sustainable future.”
