Dusting off the office heaters as the temperature drops?
As lower temps spread across the South in the coming months, plug-in space heaters, fan heaters, and oil-filled radiators are coming out of storage.
Because portable heaters draw heavy, continuous electrical current (often 2000W–3000W), they can cause localised electrical fires and socket damage in UK workplaces and rental properties.
Before plugging them back in, make sure your team or tenants are following these 3 safety tips:
1️⃣ NEVER plug a heater into an extension lead. High-draw heaters can easily melt extension blocks and overload daisy-chained sockets. Plug them directly into a wall outlet.
2️⃣ Inspect for storage damage. Crushed flexes, frayed wires, or dust-clogged vents can spark internal overheating.
3️⃣ Ensure up-to-date EET / PAT testing. High-use thermal appliances need regular electrical safety checks to verify earth continuity and insulation integrity.
Keep your workplace warm and compliant this autumn. Our City & Guilds-qualified engineers provide fast, low-disruption EET/PAT testing and EICR inspections across Surrey, Sussex, Kent, and London.
