- The fuse box/consumer unit may show you which room or area is tripping (the areas they link to are sometimes named in the box)
- If it does, you can just concentrate on that area
- If it doesn’t, you’ll have to look at it room by room
- Go around the house looking for the room where either the lights or the things plugged in aren’t working
- Unplug everything in that room and switch off the immersion heater too
- Switch the tripped switch to the ON position again
- And then plug things in again one by one until the trip goes again
- When it goes off again, you’ll know the last thing you put in was what’s causing the problem
- If it is one of our appliances, report it to us as a repair.
