A council has said its staff will receive “training” after the lights in one of its buildings were left on during the night.

Cornwall Council apologised after a member of the public complained that one of its buildings was lit up “like a Christmas tree” during an energy crisis.

On Saturday, a dog walker discovered a fully illuminated Chy Trevail building in Bodmin, which accommodates more than 600 staff.

The witness, who saw the building lit up with screens left on at 9.30pm, said: “I was out dog walking last night at Chy Trevail in Bodmin and I noticed the place lit up like a Christmas tree.

“How can the council justify leaving all the lights and TVs on? We’re constantly told there is an energy crisis.

“They put our council tax up. For what reason? Because they have forgotten to employ staff that are qualified to use a light switch?”
