Are plug-in heaters safe? A UK checklist
Desk research, not a hands-on test · Last reviewed · Disclosure
Plug-in heaters are safe when they're properly made and used correctly. But cheap imports sold online don't always meet UK standards. Use this checklist before you buy any heater, including the Keilini Heater Pro.
Before you buy
- Fused UK plug: a moulded three-pin plug, not an EU plug with a travel adaptor.
- Traceable maker: a named manufacturer or importer with a UK or EU address.
- Markings: UKCA or CE, with the rated voltage and wattage on the label. A marking alone doesn't prove independent testing.
- Protection: an overheat cut-out and a tip-over switch.
What happened with Keilini heaters
In 2023, Electrical Safety First bought a Keilini heater from an online ad. It came with an EU plug and an unfused UK travel adaptor, which the charity said was a fire risk. We don't know if this applies to today's Heater Pro, so ask the seller before you order.
The current seller lists a tip-over switch, thermostat and timer, but these are not independently tested safety assurances. Its specifications page does not document an overheat cut-out. A timer does not make unattended or overnight use safe.
Using a heater safely
- Plug it straight into a wall socket.
- Place it on a flat, stable surface, at least 1 metre from curtains, bedding and furniture.
- Never cover it or dry clothes on it.
- Keep children and pets away, and switch it off when you leave the room or go to sleep.

›Are plug-in heaters safe to leave on overnight?
Safety charities advise against leaving portable heaters running while you sleep or when unattended.
›Is the Keilini Heater Pro safe?
The current seller lists a tip-over switch and says units are supplied for UK use, but we have not independently tested these claims or confirmed a fused BS 1363 plug. A different Keilini-branded heater tested in 2023 had an EU plug and an unfused adaptor. That finding has not been linked to this Pro model.
›Can I plug a heater into an extension lead?
It's best to plug heaters straight into a wall socket. They draw a lot of current, which can overload extension leads.
›What safety features should a heater have?
Look for a fused UK three-pin plug, overheat cut-out, tip-over switch, UKCA or CE marking with a traceable maker, and a clear instruction manual.
