Common problems
Burning Smell From The Fuse Box
Your consumer unit or fuse box smells of burning plastic or hot electrics. Treat it as an electrical fire risk: turn off the main switch if safe, evacuate if there is smoke, and call an emergency electrician.
Fuse Box Sparking
Your fuse box (consumer unit) is sparking: flashes, arcing, or crackling from the board in the hall cupboard or under the stairs. In UK homes that is an extreme electrical emergency: the unit carries the full mains load, and arcing inside it can start a fire. Do not open the cover or touch sparking parts. If the main switch is safely reachable and the unit is not on fire, turn it off. If there is smoke, flames, or any doubt, evacuate and call 999. Then book an emergency electrician. The Distribution Network Operator (DNO) may need to pull the main fuse before work can start.
