The 5 Best Portable Heaters in the UK for 2026, Compared
The heating bill lands, and the question is whether to run the whole system all evening for one room. We compared five of the most searched-for portable heaters in the UK on how fast they heat, what they draw from the socket, how they are controlled, and whether you can send them back after a cold week. One took first place by some distance.
By Daniel Hart, home editor. Updated 28 October 2026.
There is always one room. The box room that became the office, the bathroom at half six, the bedroom on the cold side of the house. The thermostat in the hall says 20 and the room says nothing of the sort.
Running the boiler all evening to fix one room heats every radiator in the house, and the bill at the end of the month shows it. So people look at a portable heater, and the questions start: will it blow the extension lead, is it safe to leave on, will it warm the room or just the chair in front of it.
A 2,000-watt fan heater with no thermostat, on the floor with a cord across the doorway, warms the room and creates three new problems.
So we compared five portable heaters people in the UK search for most: two newer compact designs sold direct by their makers, and three well-known brands most people already have an opinion about. We went through the published specifications, power draw, controls, safety features, return terms and buyer feedback, and ranked them.
The five heaters, ranked

Rank 1
WellHeater
by WellHeater
The WellHeater took first place here, and the reason is what it does not have: a cord. The whole unit hangs off the wall socket, which is why people buy it for bathrooms, box rooms, home offices and rented flats where there is no floor space to give up and nothing to trip over.
Inside are ceramic heating plates and a fan. The maker rates it for rooms of around 12 m² and says it reaches temperature in under five minutes; buyers describe it as the right size for a bathroom or a small bedroom rather than an open-plan lounge.
Two things set it apart from the usual plug-in heater. There is an antimicrobial filter in the air path, and there is a proper remote with a timer, so you can set it to come on before you get up. The thermostat is adjustable, there is a kill switch that cuts power if the unit overheats, and it shuts itself off automatically.
The official site gives 30 days to send it back for a refund, and at the time of writing lists it at up to 70% off.

Heatoor
by Heatoor
The Heatoor is the one on this list rated for a big room: the maker puts it at up to 50 m², or about 538 sq ft, depending on insulation. It does that with a PTC ceramic element and what the maker calls 360° circulation, pushing warm air around rather than straight ahead.
It is also the only one here with a cooling fan mode, so it does not go into a cupboard in April. The casing stays cool to the touch, there is an overheat cut-off and an automatic shut-off, and the box includes the remote, a wall-mount kit and the user guide.
Control is by touchscreen or remote, with a timer. Buyers talk about plugging it in under a desk and the room being warm within a couple of minutes, and about how quiet it is.
The official site gives 30 days to return it and a one-year limited warranty on top.

Choose the Heatoor when the room is the problem: a living room, an open-plan kitchen, a garage office. For a bedroom it is more heater than you need.

Pro Breeze Ceramic Heater
by Pro Breeze
Pro Breeze is the UK's default budget ceramic heater: 2,000 W on high, 1,200 W on low, a dial thermostat, oscillation and a carry handle. For the price it does a lot.
It is a floor heater with a short cord, it is not quiet on high, and 2,000 W is the full load of a UK socket, so nothing else goes on the same extension lead. Returns are through the retailer.

Dreo Atom One
by Dreo
Dreo's compact ceramic heaters are the ones you see most on the big marketplaces, and they are decent: a fast ceramic element, oscillation on most models, tip-over and overheat protection, and a reasonable price.
What keeps them off the top of this list is that they are floor heaters with a cord and a full 2,000 W draw on high. You give up floor space, you get a cord across the room, and nothing else goes on the same extension lead. The return policy is whatever the retailer offers, usually 30 days in original condition.

Dimplex Oil-Free Radiator
by Dimplex
Dimplex is the brand British households trust for fixed heating, and its portable radiators are solid, silent and slow. They warm a room evenly and keep it there, which is lovely in a lounge you are in all evening.
They are also heavy, they take a lot of floor, they take fifteen to thirty minutes to make a difference, and they cost two to three times what the compact heaters here cost. Returns are through the retailer.

Why the WellHeater came first
Three things decided it. The first is the shape. It has no cord and no footprint: the whole unit hangs off the wall socket. In a bathroom, a box room or a rented flat, that is the difference between a heater you leave in place all winter and one you keep tripping over.
The second is the control. It has a touchscreen, a remote and a timer, so it comes on before you get out of bed, and a thermostat so it holds the room rather than cooking it. Of the three big brands here, only some models offer a remote and none a timer at this price.
The third is the return terms. Thirty days to send it back after using it, from the maker. The big-brand heaters follow the retailer's policy, which usually means original condition.
Who should not buy it: anyone heating a large lounge or an open-plan kitchen. For that, the Heatoor in second place is rated for a room four times the size.

How to choose a heater for one room
Most people shopping for a space heater are not trying to heat the house. They have one cold room: a bedroom over the garage, a home office at the end of the hall, a bathroom at six in the morning. Here is what matters for that job.
Where it will live
A floor heater needs a square foot of clear floor and a cord that does not cross a doorway. A plug-in heater needs a socket at a sensible height with nothing hanging over it. A wall-mounted unit needs a wall. Decide this first; it rules out half the market.
Power draw
A full-size heater pulls 1,500 W in North America and 2,000 W in the UK. That is the whole circuit, which is why heaters trip breakers. A unit with a lower setting, 400 W to 800 W, warms a small room just as well and leaves room on the circuit for a lamp and a laptop.
Controls
A thermostat is not optional: without one the heater runs flat out until you remember it. A remote matters more than it sounds, because the heater is usually across the room from the bed or the desk. A timer means the bathroom is warm before you get there.
Safety cut-offs
Look for overheat protection at minimum. Automatic shut-off and a cool-touch casing matter if there are children or pets. Tip-over protection matters for floor units.
The return window
A heater is judged in the first cold week, not in the box. A maker that gives 30 days to send it back after use is telling you something about the product. Retailer returns often require original condition.
What to avoid
Heaters with no thermostat
They run until the room is too hot, then you turn them off, then the room is cold again. That cycle is where the electricity goes.
Buying for the whole house
A space heater is for a space. If the whole house is cold, the answer is the furnace, insulation or a heat pump, not three space heaters.
Unknown sellers on marketplaces
Ceramic heaters are easy to copy badly. Buy from the maker's own site or a retailer you can walk into.
Questions people ask before buying
How big a room can a compact heater actually warm?
Go by the maker's rating and treat it as a ceiling, not a promise: a drafty room with a high ceiling will feel like a bigger room than its floor area says. Of the five here, the Heatoor carries the largest rating (up to 538 sq ft); the plug-in WellHeater is rated for around 130 sq ft.
Will a 1,500 W heater trip my breaker?
It can, if it shares a circuit with another heavy load. That is the practical case for the lower-draw units here: the plug-in heaters draw far less than a full-size tower, and the Cozy Cove Pro runs on 400 W or 800 W.
Is it safe to leave one on overnight?
All five have an overheat cut-off; the Heatoor and WellHeater also shut off automatically. Follow the maker's instructions on clearance, and never run any heater from a damaged socket or a coiled extension lead.
Can I return it after using it?
The WellHeater and Heatoor official sites give 30 days to send it back for a refund. The big-brand heaters follow the retailer's policy, which often means unopened or original condition.
Why are the big brands lower on the list?
Not because they are bad. They are floor heaters with a cord and a full-power draw, sold with retailer-only returns. The heaters above them are lighter, controllable from across the room, and come with a money-back window.
