Quick answers
- What's the cheapest electric heater to run?
- Every plug-in electric heater turns almost all its electricity into heat, so the cheapest to run is the one you control best: a thermostat, timer and heating only the room you're in. Read more
- Are wall heaters safe?
- A good wall heater with an overheat cut-out and auto-off, fitted out of reach and kept clear of curtains, is a safe choice for most homes. Read more
- How much does a 2kW heater cost per hour?
- About £0.53 an hour at full power at the Ofgem price cap of 26.32p per kWh — less once a thermostat is holding the room. Read more
- Can renters fit a wall heater?
- Usually yes with your landlord's OK — a plug-in heater fixed with two screws leaves only two small holes to fill when you move. Read more
- Do I need an electrician?
- Not for a plug-in wall heater like WarmFall: it fixes with two screws and plugs into a normal UK socket. Read more

Common questions
Are these heater guides free?
Yes. All our guides are free to read, written for UK homes and updated when energy prices change.
Where do your running-cost figures come from?
We use the current Ofgem energy price cap average unit rate (26.32p per kWh for 1 Oct–31 Dec 2026). Your own tariff may be higher or lower.
Which electric heater is best for an older relative?
Look for an overheat cut-out, automatic switch-off, cool-touch casing and simple controls. Our guide to heaters for the elderly covers what to check.
Can an electric heater replace central heating?
For one or two rooms, yes, it can be a practical top-up. For a whole house, a single plug-in heater is not a replacement for central heating.
What size heater do I need for my room?
A 2000W heater like WarmFall suits rooms up to about 25m². Larger or draughty rooms may need more heat.
Are the guides just adverts for WarmFall?
We sell WarmFall and say so. The guides give honest pros and cons, including when WarmFall is not the right choice, and link to independent UK sources.
