When the power dies in part of your home, a tripped circuit breaker is usually the cause — and resetting it is simple and safe. A breaker trips on purpose, to protect you, so the real job is finding what overloaded it.
Reset it
- Find your consumer unit / fuse box (often by the front door, in a hallway, or a cupboard).
- Look for a switch that's flipped to the OFF or middle position while others are ON.
- Flip it fully OFF first, then back ON — a firm, complete switch.
- Power should return to that circuit.
Find out why it tripped
A breaker trips because a circuit was overloaded or something faulty is drawing too much current. Before resetting, unplug whatever was running when it went (a heater, a kettle, a faulty appliance).

When to stop and call an electrician
If it trips again immediately, keeps tripping, you smell burning, or see scorch marks — stop. Don't keep forcing it on. That's a fault that needs a qualified electrician.
