When the suitcases are packed and your out-of-office is on, your home’s electrics are probably the last thing on your mind. But leaving a property unoccupied—even for a short getaway—can create unexpected electrical hazards or lead to costly surprises. Whether you’re heading off for a weekend or a month, a bit of preparation can save you from returning to blown fuses, tripped circuits, or worse, a fire caused by faulty wiring.
A properly maintained electrical system not only keeps your home safer but can also help lower your energy bills while you’re away. With a little foresight and the right steps, you can walk out the door knowing your home is secure and running efficiently behind the scenes.
Before you zip that final suitcase, take a few minutes to prep your home’s electrics. You’ll thank yourself later.
Why Electrical Maintenance Matters When You’re Away
Risks of Leaving Your Home Unattended
An empty home can seem like a playground for hidden faults. Electrical systems, though generally reliable, are still prone to issues when left idle. Small problems—like a flickering socket or overworked extension lead—can snowball without someone there to catch the signs. Heat build-up from always-on devices or rodents nibbling through wiring can create serious hazards when there’s no one around to intervene.
Insurance companies often have clauses around how long a property can be left empty without notification. If damage occurs while you’re away, they may request proof that safety checks were carried out prior to departure. That alone makes electrical prep more than just a ‘nice-to-do’.
Common Electrical Issues in Vacant Properties
- Tripped RCDs or circuit breakers due to power surges.
- Fridges or freezers switching off unexpectedly, leading to spoiled food.
- Plugged-in appliances on standby drawing unnecessary power.
- Fire risk from faulty wiring or unattended electrical faults.
- Deterioration of older wiring and fittings from heat or damp build-up.
These risks aren’t theoretical—they crop up often. That’s why a short checklist before you leave is more valuable than it might seem.
Safety Checks Before You Leave
Conduct an EICR (Electrical Installation Condition Report)
An EICR is the gold standard for electrical safety in the UK. While not legally required for all homeowners, it’s highly recommended—especially for those who let their properties or plan to leave them vacant. An EICR highlights defects, non-compliances with the latest regulations, or potential dangers such as outdated consumer units or damaged wiring.
Holiday let owners, in particular, should be aware that although there isn’t a direct legal requirement, the Electricity at Work Regulations 1989 still apply. These put the responsibility on you to ensure all electrical systems are safe. An up-to-date EICR is a solid line of defence.
Test RCDs and Circuit Breakers
Residual Current Devices (RCDs) are lifesavers—literally. They trip quickly when a fault occurs, preventing electric shocks or fires. Before leaving your home, press the ‘test’ button on your RCDs (usually located in your consumer unit). If they fail to trip, that’s a sign they need replacing or further inspection.
Also, keep an eye on any circuit breakers that frequently trip. It might not just be a nuisance—it could point to a deeper wiring issue that needs fixing before you go.
Unplug Non-Essential Appliances
Any device left plugged in is still drawing power—even when it’s turned off. TVs, microwaves, Wi-Fi routers, chargers, and kettles all consume small amounts of energy, which adds up over time. Worse still, they’re potential ignition points if an electrical surge occurs.
Go around the house before you leave and unplug anything that’s not critical. Leave the fridge and freezer if needed, but make sure they’re on a reliable circuit. For everything else, it’s better safe than sorry.
Fire Safety Compliance for Holiday Lets
Understanding the Fire Safety (England) Regulations 2022
If your property is used as a holiday let, fire safety compliance becomes even more essential. Under the Fire Safety (England) Regulations 2022, you must ensure all electrical systems and appliances are safe for guests. This includes fixed wiring, portable appliances, and any electrical fittings like sockets or switches.
Even if your holiday let is only occasionally occupied, you’re still legally responsible for its safety. And while PAT testing isn’t mandatory, it’s a wise precaution. The same goes for keeping records of your electrical checks—especially if you’re ever faced with a guest complaint or an insurance query.

Electrical Responsibilities Under BS 7671 and Part P
The BS 7671 Wiring Regulations—also known as the IET Wiring Regulations—form the basis of all domestic electrical standards in the UK. They require that electrical work be designed and installed to avoid hazards like electric shock or fire.
Meanwhile, Part P of the Building Regulations ensures that all new electrical installations in homes (including holiday lets) are carried out safely. If you’re leaving your property vacant for any period, checking your setup complies with Part P is a smart move—especially if guests or renters will use the property later.
Even replacing a light fitting or socket could fall under notifiable work, so always use a qualified electrician registered with a scheme like NICEIC or NAPIT. It’s not just about ticking boxes—it’s about avoiding accidents.
Remote Monitoring for Peace of Mind
Install Smart Security Systems and Timers
One of the easiest ways to keep tabs on your property while you’re away is through smart home tech. A basic smart plug can let you schedule lights to turn on and off, giving the impression someone’s home. Smart thermostats can maintain your heating efficiently or notify you of temperature drops—helpful during cold snaps.
And motion sensors? They’re not just for burglars. They can alert you to unexpected movement indoors that might point to electrical faults (like a light flickering or going on/off unpredictably).
It’s a hands-off way to stay in the loop—ideal for peace of mind without the hassle of calling neighbours for updates.
Benefits of CCTV and Smart Doorbells
CCTV systems aren’t only for catching trespassers. In some cases, smart doorbells and cameras have alerted owners to electrical faults early—like sparking from outdoor sockets or malfunctioning garden lights.
Installing a camera that covers your meter box or main consumer unit (within reason and privacy laws) could be beneficial. At the very least, these systems allow you to remotely check whether lights or devices are behaving as expected.

Energy Efficiency Tips While You’re Away
How to Reduce Standby Consumption
Many households unknowingly waste energy through what’s known as “phantom load”—the power consumed by appliances on standby. TVs, game consoles, chargers, and even microwaves continue to draw current when not in active use.
To cut this off at the source, switch off devices at the wall or use a power strip with a built-in switch for convenience. For smart homes, set up automation to power down groups of devices with a single tap on your phone.
The Energy Saving Trust estimates that UK homes spend an average of £55 a year on powering appliances in standby mode. Not massive—but unnecessary, especially when you’re not even home.
Using Smart Meters and Thermostats Effectively
Smart meters don’t just track electricity usage; they offer real-time insights that help you catch spikes or anomalies. If your energy use remains unexpectedly high during your absence, it could indicate a faulty device or unnoticed issue like a light left on.
Smart thermostats can be just as handy. You can set your heating to low-maintenance mode or frost protection to avoid frozen pipes in winter without wasting energy heating an empty home. With mobile control, you can also warm the house up before your return—ideal for winter holidays.
Professional Services to Consider
Hiring a Qualified Electrician for Pre-Holiday Inspections
If you’re going away for an extended period—or letting the property out—it’s wise to call in a professional. A quick visit from a qualified electrician can identify issues before they become expensive or dangerous.
They’ll check your consumer unit (often referred to as the fuse board), assess visible cabling, and test your safety devices like RCDs. They can also confirm your setup complies with current BS 7671 regulations and Building Regulations Part P.
Trying to tackle this yourself without the right knowledge risks invalidating insurance or worse, breaching regulations. Save yourself the stress by speaking to the experts at Wave Electrical Solutions—fully certified, reliable and local.
