What To Do If Your Power Goes Out (And It’s Not the Grid)

03 March 2026

Power gone but neighbours are fine? Learn what to check, how to reset your fuse box safely, and when to get immediate assistance from Zapline.

When the lights go out, most people assume it’s a grid issue.

But if your neighbours still have power and your street lights are on, the problem is likely inside your property.

Here’s exactly what to do next, safely and calmly.

Step 1: Check If It’s Just Your Power That Has Gone Out

Before touching anything:

Look outside - are nearby houses lit?
Check if streetlights are on.
Check your energy supplier’s outage map (if needed).

If it’s only your home, the issue is almost certainly internal.

Step 2: Go to Your Consumer Unit (Fuse Box)

Your consumer unit controls power distribution around your home.

Open the cover and check:

Has one switch flipped down?
Has the main RCD tripped?
Are multiple breakers off?

A switch in the down position usually means a circuit has tripped.

Step 3: Reset the Tripped Breaker

If only one breaker is down:

Turn off appliances on that circuit (unplug kettles, heaters, washing machines, etc).
Push the breaker fully down.
Then firmly switch it back up.

If it stays up, problem solved.

If it trips again immediately, something connected to that circuit is faulty.

Step 4: Identify the Faulty Appliance

A common cause of power trips is a defective appliance.

Typical culprits:

Kettles
Washing machines
Dishwashers
Extension leads
Electric heaters

Unplug everything on the affected circuit.

Then:

Reset the breaker.
Plug items back in one at a time.
When it trips again, the last item plugged in is likely the issue.

Step 5: When It’s More Serious

Call an emergency electrician immediately if:

The main switch won’t reset.
You smell burning.
There are sparks.
The consumer unit feels hot.
Power cuts repeatedly without appliances plugged in.
You’ve recently had water damage near wiring.

Electrical faults can escalate quickly and should never be ignored.

How It Works

Common Causes of Internal Power Loss

Overloaded circuit
Faulty appliance
Damaged wiring
Water ingress
Old consumer unit
Rodent damage to cables
Loose connections

In older properties, wiring degradation is more common than people realise.

Is It Safe to Fix Yourself?

Resetting a breaker is safe. Investigating wiring is not.

Never:

Open your consumer unit casing
Remove socket faceplates while live
Attempt DIY rewiring
Bypass safety switches

UK electrical regulations are strict for good reason.

If you have:

No lighting
No heating
No power to medical equipment
A burning smell

It’s considered urgent. Zapline will find you an Electrician on the same day.
