- Look for discoloured or warm outlets and switch plates
- Check for frayed or damaged cords on appliances
- Verify smoke detectors work and have fresh batteries
- Inspect outdoor wiring for weather damage
- Confirm circuit breakers trip and reset correctly

Seasonal Electrical Maintenance Calendar
| Season | Priority Tasks |
|---|---|
| Spring | Test outdoor lighting and sockets after winter. Check garden equipment cables. Schedule annual professional inspection. |
| Summer | Inspect air conditioning wiring. Check pool or hot tub electrical safety. Verify surge protectors still function. |
| Autumn | Test heating system electrics before cold weather. Replace smoke detector batteries. Check attic wiring before insulation work. |
| Winter | Monitor for overloaded circuits from heaters. Test holiday lighting circuits. Ensure RCDs protect wet-area outlets. |
Warning Signs You Need an Immediate Inspection
- Frequent circuit breaker trips
- Flickering or dimming lights without obvious cause
- Burning smell from outlets or switches
- Buzzing or crackling sounds from the fuse box
- Sparks when plugging in appliances
- Outlets or switches that feel warm to the touch
- Electrical shocks when touching appliances
- Your home is over 25 years old and has never been inspected
What a Full Electrical Inspection Covers
A certified inspector will check:
- Consumer unit condition and labelling
- Earthing and bonding adequacy
- Cable condition, routing, and support
- Socket, switch, and fixture condition
- RCD functionality and trip times
- Circuit loading and cable sizing
- Outdoor and bathroom zone compliance
The result is a formal Electrical Installation Condition Report (EICR) grading each circuit as satisfactory or requiring action.

FAQ
How often should I get a full electrical inspection?
For owner-occupied homes, every 10 years is the minimum recommendation, though every 5 years is safer for homes over 25 years old. Rental properties typically require inspections every 1-5 years depending on local regulations. Always get one before buying or selling a property.
Can I do my own electrical inspection?
You can and should do regular visual checks ā looking for damage, testing RCDs, and monitoring for warning signs. However, a formal inspection requires specialised testing equipment and a qualified electrician. Only a licensed professional can issue a valid safety certificate.
What happens if my home fails the inspection?
The inspector grades issues by severity. Code C1 (danger present) requires immediate attention. Code C2 (potentially dangerous) needs action soon. Code FI (further investigation) means more testing is needed. Your electrician can quote remedial work based on the report.
