Emma Pamplin, director of customer excellence at the National Grid, said staff were getting in touch with the most vulnerable customers on the priority services register to check they were “safe and well, and offering additional support where needed”.

“Our welfare vans provide comfort and care in the most impacted communities, because we know that restoring power is only part of the support our customers need.”

“Storms can be unsettling, and we’re here to keep our customers safe, informed and supported every step of the way.”

Cornwall Council said teams from National Highway had cleared more than 550 reports of fallen trees and other highway damage over the last 24 hours.

It said: “Clearance will be continuing over the weekend, prioritising high traffic areas and urgent community issues.

“Thank you for the overwhelming community support and understanding we have experienced so far.

“We ask that you continue to be patient and support our teams to complete this vital job.”
