At some point everything goes quiet: the lights go out, the fridge falls silent and you wonder where it is going wrong. A power cut is annoying, but usually easy to pinpoint if you know where to look.

On this page you can read how to safely make a first diagnosis yourself, how to distinguish a problem with the network operator from a fault in your own installation, and when you are best to call straight away for an urgent intervention.

Grid operator or your own installation?

The first question is always: is the problem outside or inside your home? Check whether your neighbours also have no power and whether the street lighting is still on. If the whole neighbourhood is in the dark, it is probably a fault on the grid operator's network and there is nothing you can do yourself.

If you are the only one without power, the cause is almost certainly in your own installation: your main fuse, a circuit breaker, the residual current device or a faulty appliance overloading the circuit.

What you can safely check yourself

Go to your fuse box and check whether a circuit breaker has tripped or the residual current device (RCD) is in the down position. If a switch is down, this indicates which circuit has the problem.

First unplug appliances on that circuit from the socket and then try to flip the switch back up. If it stays up, the issue was with one of the disconnected appliances. If it trips again immediately, do not touch anything else and call a professional.

When to call urgently

Call immediately if you smell burning, if you can see sparks or soot at the consumer unit or a socket, or if the RCD keeps tripping again and again as soon as you reset it. That points to an earth leakage fault or a wiring fault that you must not tackle yourself.

Also, if the whole installation stays dark while your neighbours still have power, and you cannot find a tripped switch, an urgent call-out is warranted. In that case, contact us by phone for a rapid response.

Quick checks before you call

Neighbours and street

Is the whole neighbourhood without power too? Then it is a grid outage, not a problem in your home.

Fuse box

Check whether a circuit breaker or the residual current device has tripped.

Unplug appliances

Unplug the appliances on the affected circuit and try switching it on again.

Smell or sparks

Burning smell, sparks or soot: do not touch and call right away.

Step by step during a power cut

  1. 1

    Look outside

    Check whether the neighbours and the street lighting are also without power.

  2. 2

    Open the fuse box

    Find the tripped circuit breaker or residual current device.

  3. 3

    Take the load off the circuit

    Unplug the devices and switch the circuit in question back on.

  4. 4

    In doubt? Call

    If the problem persists, you smell something or see sparks: call for an urgent callout.

Frequently asked questions

How do I know if the problem is with the grid operator?
Check whether your neighbours and the street lighting are also without power. If they are, it is a fault on the grid and there is nothing you can do yourself. If only your home is in the dark, the cause lies in your own installation.
Can I reset a tripped fuse myself?
You may reset a circuit breaker or residual current device, after unplugging the appliances on that circuit. If the switch trips again immediately or you smell burning, do not touch anything else and call a professional.
What do I do if part of the house has power and part does not?
Then a separate circuit has tripped, usually due to overload or a faulty appliance on that circuit. Find the circuit breaker concerned, take the load off the circuit and switch it back on. If that does not work, an electrician will inspect the circuit on site.
When is a power cut an emergency?
If there is a smell of burning, sparks, soot, hot sockets or a residual current device that trips immediately every time, there is a real risk. In that case, do not touch anything else and call for an urgent call-out.

Still without power?

If the checklist does not solve it, or you smell or see something suspicious at the fuse box, call us for an urgent call-out and we will come and check your installation quickly.
