In case of an electrical fire, switch off the electrical supply from the fuse box (if safe to do so). Do not throw water on the fire as it conducts electricity! If you don’t have an extinguisher (carbon dioxide and dry powder are only recommended for electrical fires, not foam) smother the fire with a blanket to starve the fire of oxygen (if safe to do so). If it is or about to get out of control, call 999 without delay.
