An industrial unit containing around 10 cars was destroyed and part of a further single-storey industrial unit was damaged by fire. An electric vehicle was also destroyed by the blaze and crews ensured the lithium battery was cooled. There were no reports of any injuries.

The cause of the fire is under investigation.
