29 Common Types of Electrical Problems in the House (2025 Edition)

Why Electrical Safety Matters in 2025

New Regulations and Legal Requirements

In recent years, electrical safety standards have tightened, especially in the private rented sector. Under current legislation, new and existing tenancies must have an electrical installation condition report (EICR) carried out by a competent person. This ensures that the electrical installation is safe for continued use.

The Role of Local Authorities

Your local housing authority may intervene if landlords fail to make necessary repairs. Sometimes, local government can enforce work based on published guidance and best practice.

Common Electrical Problems in UK Homes

1. Flickering or Dimming Lights

Dimming lights, often caused by faulty wiring or overloaded circuits, may indicate poor wire connections or a failing light switch.

2. Frequent Tripping of Circuit Breakers

A constantly tripped breaker usually signals that a circuit is drawing too much electrical current, possibly from overloaded appliances or a fault.

3. Buzzing Sounds from Outlets or Switches

It could mean a dangerous electrical fault if you hear humming or buzzing near a socket outlet or switch. Don’t ignore it.

4. Burning Smells

That acrid smell near an outlet could be the start of a fire. Cut the power and call a reliable electrician immediately.

5. Loose Power Outlets

A wobbly socket isn’t just annoying; it could mean wire connections are detached, risking short circuits.

6. Overloaded Power Strips

Plugging too many electrical appliances into one outlet is a recipe for overheating and fire.

7. Warm or Discoloured Switch Plates

Excess heat or black marks around outlets often suggest internal damage or incorrect wiring.

8. Old or Outdated Wiring

Older homes often contain aluminium or cloth-insulated wiring, which falls short of modern regulations.

9. Faulty Light Switches

A switch that doesn’t work or behaves oddly could point to damaged wiring or a deeper electrical fault.

10. Tripping RCDs (Residual Current Devices)

When your RCD trips, it’s doing its job protecting you from dangerous surges. But frequent trips mean there’s a persistent problem.

11. Faulty Appliances

Old or damaged electrical equipment, like washing machines, can overheat, trip breakers, or even cause fires.

12. Outdated Consumer Unit

Your consumer unit (or fuse box) should be updated every 10–15 years. A new panel with modern breakers improves safety.

13. Lack of Earthing

No earthing = high risk. Without proper earth connections, fault currents can turn deadly.

14. Missing or Broken GFCI Outlets

Ground Fault Circuit Interrupters are a must in kitchens and bathrooms. Faulty ones need remedial work right away.

15. Frequent Bulb Burnouts

If your bulbs keep blowing, it might be due to high voltage or unstable light circuits.

16. Exposed Wiring

Any visual inspection that reveals bare or frayed wires demands immediate repair.

17. Sparking Outlets

If plugging in a device causes a visible spark, turn off the breaker and seek professional help.

18. Dead Outlets

Dead sockets are usually due to a tripped breaker, disconnected wires, or internal damage.

19. Incorrectly Installed Switches

DIY gone wrong. A wrongly wired switch can result in shock or failure of the connected appliances.

20. Lack of a Safety Certificate

It’s a legal requirement for landlords to obtain an electrical installation certificate after any major electrical work.

21. Infrequent Electrical Safety Checks

Electrical safety checks should be carried out every 5 years in rental homes, or sooner for multiple-occupancy dwellings.

22. Wiring Not to Code

If your wiring doesn’t meet wiring regulations, your insurer may not cover damage in the event of an electrical fire.

23. Inadequate Outdoor Lighting Protection

Outdoor lighting must be waterproofed and properly grounded to avoid electrical faults from weather exposure.

24. Unlabelled Breaker Panel

A poorly marked breaker panel wastes time during emergencies and makes it hard to identify issues.

25. Appliances Without PAT Testing

Portable appliance testing (PAT) is essential for rented properties to verify the safety of electrical appliances.

26. Improper Use of Extension Leads

Never daisy-chain extension cords. It's unsafe and often exceeds the capacity of the original installation.

27. Poor DIY Repairs

Unqualified tinkering often makes things worse. Use a licensed electrician to carry out repairs.

28. Delayed Remedial Work

Landlords must carry out remedial work in due course after receiving a failed electrical installation condition report.

29. No Plan for Next Inspection

You're likely overdue if you don’t know when your next inspection is due. Ask your local electricians for a routine check-up.

How to Stay Compliant and Safe

Hire a Competent Electrician

Only a competent person should carry out inspections or major work. Check for JRO Electrics at NICEIC registration and local reviews.

Request Written Confirmation

After repairs or inspection, get written confirmation and update your records, especially for new tenants or existing tenancies.

Visual Inspection Matters

Regular DIY checks for scorch marks, buzzing sounds, or frayed wires help you spot issues before they escalate.

Follow the Guidance

Published guidance from the local authority or the government outlines best practices for landlords, homeowners, and tenants.

Understand Your Responsibilities

Whether a landlord or homeowner, understanding your duty under new regulations is crucial for staying legal and safe.

Conclusion

Electrical problems may start small, but they rarely stay that way. As shown in our 29 common types of electrical problems in the house (2025 edition), many are preventable with regular checks, professional help, and smart awareness. Remember, electricity isn’t something to take lightly. Stay ahead of the risk by investing in inspections, maintaining your electrical installation, and always using a reliable electrician when needed.
