Preparing your workplace for winter: an electrical safety checklist

9th October 2026

As temperatures drop and the days get shorter, electrical systems in the workplace can come under extra pressure. Inevitably, heating appliances are used more frequently, lights are switched on for longer periods and wet weather can create additional risks for outdoor electrical equipment.

Taking a few simple precautions before winter sets in can help reduce the risk of electrical faults, disruption and potential safety issues.

Check heaters and portable appliances

Portable heaters are often used more often during colder weather, so it’s important to check them for damaged plugs, cables or casings before using them.

Avoid overloading extension leads and make sure portable electrical appliances are being inspected and maintained appropriately. PAT testing should form part of your electrical maintenance programme, so it’s advisable to check that all electrical equipment is up to date.

Inspect sockets and extension leads

Look out for signs of overheating, scorching or visible damage around sockets, plugs and extension leads. If your workplace regularly relies on extension leads or multi-way adaptors, consider adding fixed sockets to provide a safer and more practical long-term solution.

Check lighting

With darker mornings and evenings, make sure internal and external lighting is working correctly, particularly around entrances, car parks, paths, stairways and other areas where poor visibility could increase the risk of accidents. Emergency lighting should also be regularly checked and maintained so that it’s ready to operate if there’s a loss of power.

Don’t forget outdoor electrics

Rain, frost and damp conditions can increase the risk of problems with outdoor electrical equipment. Check external sockets, lights and cables for signs of wear or damage and make sure all outdoor equipment is suitable for the environment in which it’s being used.

Look out for warning signs

Flickering lights, tripping circuits, buzzing or crackling sounds, hot sockets and burning smells should never be ignored. Regular electrical inspections and maintenance can help identify potential problems before they lead to disruption or more serious issues.
