Tripping electric: The basics

21st June 2026

Most of us have experienced the electric tripping: one minute everything is working normally, the next you’re plunged into darkness or notice that the usual noises of dishwashers, ovens or the radio have suddenly gone silent.

The good news is that electrical trips are often a sign that your home's safety systems are working correctly. Understanding the basics can help you identify potential causes and know when it's time to call a professional.

What does "tripping electric" mean?

When people say their "electric is tripping", they usually mean that a switch in the consumer unit (fuse box) has automatically turned off.

This happens when the electrical system detects a fault that could be dangerous. The trip helps protect your home from electrical fires, damage to appliances, and the risk of electric shock.

Common reasons your electrics keep tripping

Faulty appliances

One of the most common causes of electrical trips is a faulty appliance. Kettles, toasters, washing machines, tumble dryers, and other household appliances can develop faults that cause a circuit to trip.

If the electrics trip whenever a particular appliance is used, that appliance may be the source of the problem.

Overloaded circuits

Running several high-power appliances on the same circuit can sometimes overload it, causing a breaker to trip. This is more common when using electric heaters, air fryers, tumble dryers, or electric showers simultaneously.

Water or moisture

Water can cause electrical faults, particularly in outdoor sockets, garden lighting, bathrooms, or appliances exposed to damp conditions.

Damaged wiring

Damaged or ageing wiring can lead to recurring trips and should always be investigated by a qualified electrician. Signs may include flickering lights, burning smells, warm sockets, or unexplained power loss.

Things you can check yourself

Before calling an electrician, try a few basic checks:

· Identify which switch has tripped in the consumer unit.

· Unplug appliances connected to the affected circuit.

· Reset the breaker.

· Plug appliances back in one at a time to identify any faulty equipment.

· Check for visible damage to plugs, cables, or sockets.

Never continue using electrical equipment that appears damaged.

When not to reset a trip

Avoid repeatedly resetting a breaker if:

· It trips immediately every time

· You smell burning

· You hear buzzing or crackling sounds

· The consumer unit feels hot

· There are visible signs of damage

Repeatedly forcing a breaker back on can make a fault worse and may create a safety risk.

When to call an electrician

You should contact a qualified electrician if:

· The electrics continue tripping after basic checks

· You cannot identify the cause

· There are signs of damaged wiring

· Water has entered electrical equipment

· Multiple circuits are affected

· The consumer unit appears faulty

A tripping electrical system is often your home's way of protecting you from a potentially dangerous fault. While a faulty appliance or temporary overload may be the cause, repeated trips should never be ignored. If the problem keeps returning, a qualified electrician can safely diagnose the issue, carry out any necessary repairs, and ensure your electrical system remains safe and reliable. Was this useful?

What should I do in an electrical emergency at home?

Switch off the power at the consumer unit if it's safe to do so - don't try to unplug a sparking appliance by hand. If there's an electrical fire, don't use water - use a dry powder or CO2 extinguisher, or get outside safely and call 999. If someone's received a shock, don't touch them until the power is definitely off - use something non-conductive like a wooden broom handle to separate them from the source. Call 999 for anything serious. Once the danger's passed, don't turn the power back on until an electrician has checked things over.
Can I have an EV charger installed at home?

Yes, and for most homes with off-street parking it's a pretty straightforward job taking half a day or so. A dedicated 7kW home charger will charge most EVs overnight and is much faster and safer than using a standard three-pin socket for regular charging. It needs to be installed by a qualified electrician and must comply with wiring regulations. The government's OZEV scheme has offered grants for home charger installation - worth checking the current position on GOV.UK.
What is PAT testing and do I need it?

PAT testing checks electrical appliances for safety - things like kettles, laptops, extension leads, and power tools. For most homeowners, there's no legal requirement. Landlords do need to make sure appliances in a rental are safe though, and it's required in most workplaces too. If you run a business from home or regularly use second-hand electrical equipment, it's worth getting done. An electrician or PAT specialist can tell you what applies to your situation.
Why does my circuit breaker keep tripping?

Breakers trip to protect the circuit - it's the system doing its job. The usual culprits are too many high-draw appliances on one circuit, a single faulty appliance, damaged wiring, or a breaker that's starting to fail. If it keeps tripping even after you've unplugged things, or several breakers are going at once, stop resetting it and call an electrician. Persistent tripping can be a sign of something more serious.
How do I know if my home's electrics are safe?

Watch out for breakers tripping frequently, flickering lights, scorch marks around sockets, burning smells, buzzing from the consumer unit, or sockets that feel warm. If your property was built before the 1970s, the wiring may not meet current standards even if everything seems to be working fine. An Electrical Installation Condition Report (EICR) is the proper way to check - legally required for landlords, and worth doing for any home that hasn't been looked at in the past ten years.
What is an EICR and do I need one as a homeowner?

An EICR is a formal check of your home's wiring, sockets, and consumer unit by a qualified electrician - think of it as a health check for your electrics. It flags anything that's deteriorated, isn't up to standard, or needs attention. It's legally required for landlords but optional for homeowners, though it's a smart move if you're buying a property, haven't had one in over ten years, or are planning significant electrical work.
What is RCD protection and does my home have it?

An RCD (Residual Current Device) is a safety switch that cuts the power almost instantly if it detects a fault, dramatically reducing the risk of electrocution or fire. Modern consumer units should have RCD protection across most circuits. To check if yours does, look at your consumer unit - if you see buttons marked 'RCD' or 'T', you've got some protection in place. If it's just old-style fuses with no RCDs, it's worth speaking to an electrician about an upgrade.
What electrical work legally requires a qualified electrician in the UK?

Under Part P of the Building Regulations, certain electrical work has to be done by a registered electrician - or at least notified to your local authority. This covers most bathroom work, replacing or installing a consumer unit, adding new circuits, and anything near a pool or outdoor structure. Straightforward like-for-like swaps in other rooms might be fine as DIY, but anything involving the consumer unit, rewiring, or new circuits should really go to a professional.
