Why Winter is High-Risk for Electrical Issues

• Electrical fires increase by 40% during winter months
• Portable heaters are leading cause of winter electrical fires
• Increased load on circuits from heating devices
• Older wiring may not handle modern heating demands
• Power bills can spike 50-100% without efficiency checks

Before-You-Start Safety Checklist

Know your switchboard location

Ensure all adults know where it is and how to turn off power in an emergency

Test smoke alarms

Press the test button. Replace batteries or units if not working

Check RCDs (safety switches)

Press test button monthly. If it doesn't trip, call an electrician immediately

Have emergency numbers ready

Save your electrician's number. Fire: 000 (AU) or 111 (NZ)

Heating Equipment Safety

Portable Heaters

Keep 1 metre clearance from curtains, furniture, and bedding

Never leave running unattended or while sleeping

Don't use extension cords—plug directly into wall outlet

Check for frayed cords or damaged plugs

Place on flat, stable surface—never on carpet if specified

Ensure tip-over switch is working (turns off if knocked over)

Electric Blankets

Inspect for worn cords, scorch marks, or damaged wires

Never use if wet or damp

Turn off before getting into bed (use to pre-heat only)

Don't fold or crease when in use

Replace if more than 10 years old

Heat Pumps & Air Conditioners

Clean filters monthly during heavy use

Check outdoor unit is clear of debris and vegetation

Listen for unusual noises that may indicate electrical issues

Have professionally serviced annually

Circuit & Switchboard Check

Warning Signs You Need an Electrician

Circuit breakers tripping frequently

Flickering lights when heater turns on

Burning smell from outlets or switches

Warm or discoloured power points

Buzzing sounds from switchboard

Power points that feel loose

⚠️ If you notice any of these, call a licensed electrician immediately. Don't ignore warning signs.

DIY Visual Inspection

Check switchboard for signs of overheating (discolouration, melting)

Ensure switchboard has clear access (not blocked by storage)

Inspect visible wiring for damage or wear

Test all RCDs (safety switches) - they should trip when tested

Check that circuits are properly labelled

Winter Energy Efficiency Tips

Reduce Your Power Bill

• Set heating to 18-20°C (each degree higher adds ~10% to cost)
• Use timers so heating only runs when needed
• Close doors to unused rooms
• Use draft stoppers under doors
• Draw curtains at night to retain heat
• Dress warmly before turning up heating

Electrical Efficiency

• Replace incandescent bulbs with LEDs
• Unplug devices not in use (standby power)
• Use power strips with switches
• Maintain heating systems for efficiency
• Consider upgrading to energy-efficient appliances
• Install programmable thermostats

Outdoor Winter Safety

Exterior Power Points & Lighting

Check weatherproof covers are intact
Ensure outdoor lights are working (shorter days = more use)
Clear leaves from outdoor light fittings
Check for water damage to external wiring

Clothes Dryers

Clean lint filter after every use
Check and clean exhaust vent monthly
Don't overload the dryer
Never run while sleeping or away from home

When to Call a Professional

Some electrical work should only be done by licensed electricians. Don't DIY the following:

Switchboard upgrades

Circuit additions

New power point installations

Fault finding and repairs

RCD installation or testing

Smoke alarm installation
