Small space heaters in the UK: how to choose the right one
Desk research, not a hands-on test · Last reviewed · Disclosure
The "best" small heater depends on whether you want to warm yourself at a desk or keep a whole room warm. This guide explains the main types and the features worth paying for. We haven't tested or ranked individual products.
Types of small heater
| Type | Good for | Trade-offs |
|---|---|---|
| Ceramic fan heater | Quick, direct warmth for one person | Fan noise; heat fades quickly when off |
| Oil-filled radiator | Steady heat for a room for longer periods | Slow to warm up; heavy |
| Convector heater | Background room heat | Slower at warming a person |
| Halogen or infrared | Warming whoever is in front of it | Bright glow; limited reach |
Features that matter
- A published wattage, so you can estimate running costs.
- An adjustable thermostat and more than one heat setting.
- Overheat and tip-over protection.

These features have not been independently verified. Rated wattage and a fused BS 1363 plug remain undocumented; the current specifications page does not list an overheat cut-out.

›What is the best small heater for a bedroom?
An oil-filled radiator with a thermostat gives steady, quiet heat. A small fan heater warms you faster but works best close up. Don't leave either running while you sleep.
›What size heater do I need?
As a rough rule, small rooms need around 1–1.5kW and larger rooms need 2kW or more. Insulation, ceiling height and draughts all make a difference.
›What is the best heater for a desk or office?
A compact ceramic fan heater with a thermostat and tip-over switch is a popular choice for warming one person.
›Which portable heater is cheapest to run?
The lower the wattage, the lower the hourly cost, but also the less heat it gives. A thermostat helps you avoid wasting energy.
