No Power In The Whole House
Your entire home has lost electricity. No lights, no sockets — everything is dead.
What would yours cost?
We'll tell you the price for this, then find a local electrician to do it.
What's happening?
A complete loss of power to your home means no circuit in the property is working. This could be caused by a supply issue from your energy provider, a main fuse failure, or a fault in your consumer unit. It is one of the most common electrical emergencies in UK homes.
What usually causes it?
- Main fuse (cut-out fuse) has blown
- Power cut in your area from the Distribution Network Operator (DNO)
- RCD or main switch in consumer unit has tripped
- Faulty meter or meter isolation switch turned off
- Damaged supply cable (especially after building work)
Is it dangerous?
A total power loss itself is not immediately dangerous, but the underlying cause could be. If you smell burning, see scorch marks, or the power loss followed a bang or flash, treat it as an emergency. Do not attempt to reset anything until you have ruled out a serious fault.
Can I fix it myself?
First, check if your neighbours also have no power — if so, it is a supply issue and you should contact your DNO (not your energy supplier). Check your consumer unit: if the main switch or RCD has tripped, try resetting it once. If it trips again immediately, do not keep resetting it. Never touch the main fuse (the sealed unit before the meter) — this belongs to the DNO and is illegal to tamper with.
When should you call an electrician?
Call an electrician if your consumer unit trips again after resetting, if the main switch will not stay on, or if you cannot identify why the power is out and your neighbours have power. If there is any sign of burning or damage, call an emergency electrician immediately.
What will the electrician actually do?
- Inspect the consumer unit and main switch for faults
- Test the incoming supply to confirm power is reaching the property
- Use insulation resistance testing to identify faults on circuits
- Repair or replace any faulty protective devices (RCDs, MCBs)
- Liaise with the DNO if the fault is on the supply side
