10 Best Heaters UK 2026
By Dale @ ukaircontracker · Updated
Quick answer
The best heater for most UK living rooms is a 2,500W oil-filled radiator: it covers 20 to 25m² and keeps giving out heat after the thermostat switches it off. A 1,500W oil radiator suits a bedroom of 12 to 15m². For heat the moment you switch on, choose a 2,000W convector or a ceramic fan heater.
- What is the best type of electric heater?
- It depends on the job. Oil-filled radiators are best for steady background heat over several hours, because they stay warm after switching off. Convector heaters warm a room faster but cool down as quickly. Ceramic fan heaters give warm air within seconds and suit a small room or a desk.
- What size heater do I need?
- As a guide from the heaters ranked here: 1,500W for a bedroom of 10 to 15m², 2,000W for a room of 15 to 20m², and 2,500W for a living room of 20 to 25m².
- Which electric heater is cheapest to run?
- Every plug-in electric heater turns all of its electricity into heat, so the running cost depends on the wattage and how long it is on, not the type. A 2,000W heater at full power costs about 53p an hour at the 26.32p/kWh price cap. A thermostat or a timer is what cuts the bill.

Photographed listing — tagged buy buttons go to the retailer, not another article.
We track every electric heater sold in the UK — oil-filled radiators, convectors, ceramic heaters and more. These are the 10 best units you can actually buy right now, ranked by power, room size and value. Updated daily.
1.
11-Fin Oil Filled Radiator 2500W
Best Value🔥 2500W🌡️ Oil-filled📐 Living rooms, 20-25m²
Eleven fins and 2,500W puts this at the top of what a plug-in oil radiator can put out, and it's priced like a budget unit despite the spec. Oil radiators hold their heat after switch-off, so they keep a room warm even once the thermostat cycles down. A built-in timer means you're not leaving it running all evening by accident.
2.
Geepas 7-Fin 1500W Oil Radiator
Best Budget🔥 1500W🌡️ Oil-filled📐 Bedrooms, 12-15m²
The cheapest genuinely useful oil radiator we track. Seven fins and 1,500W is right-sized for a single bedroom or home office, and Geepas's oil radiators are reliable enough that they're one of our most-clicked heaters two years running. Three heat settings let you dial it back overnight.
3.
Geepas 2000W Freestanding Convector Heater
Best Convector🔥 2000W🌡️ Convector📐 Quick warm-up, 15-20m²
Convector heaters warm a room faster than oil radiators — no waiting for oil to heat up — which makes this the pick if you want heat the moment you walk in. 2,000W is enough for a mid-size room, and freestanding means no wall-mounting required. Trade-off: it cools down as fast as it heats up once switched off.

4.
Geepas PTC Ceramic Heater with Cool Shot
Best Ceramic🔥 PTC ceramic🌡️ Ceramic fan📐 Spot heating, small rooms
PTC ceramic heaters are the fastest-warming option here — genuinely warm air within seconds — which suits a small room, box room, or a desk you want warm right now rather than in ten minutes. The 'Cool Shot' function doubles it as a fan for summer, so it's not a one-season purchase.
5.
De'Longhi Dragon 4 Oil-Filled Radiator
Best Premium Brand🔥 2000W🌡️ Oil-filled📐 Living rooms, 15-20m²
De'Longhi's Dragon series is the recognised premium name in oil radiators, and the Dragon 4 brings Eco mode, castors for moving between rooms, and noticeably better build quality than budget units. Costs more, but it's a heater you'll still be using in five winters — De'Longhi's oil radiators are built to outlast the cheap alternatives.
6.
De'Longhi Radia S 1500W Oil-Filled Radiator
Most Efficient🔥 1500W🌡️ Oil-filled📐 Bedrooms, 12-15m²
The Radia S is De'Longhi's thermostatic model — it holds a set temperature rather than just cycling on and off at full power, which uses noticeably less electricity over a full evening than a basic on/off radiator. If you're running a heater every night through winter, the efficiency gain pays for the price difference over a Geepas fast.
7.
VonHaus 11 Fin 2500W Oil Radiator
Best Mid-Range🔥 2500W🌡️ Oil-filled📐 Living rooms, 20-25m²
VonHaus sits between the budget Geepas units and premium De'Longhi on both price and finish. 2,500W across 11 fins covers a decent-sized living room, and the build feels a step up from the cheapest options without De'Longhi pricing. A solid middle-ground pick if you're not sure which end of the range to buy into.
8.
Russell Hobbs 1500W 7-Fin Oil Radiator
Best Small Room🔥 1500W🌡️ Oil-filled📐 Small bedrooms, 10-12m²
Russell Hobbs is a trusted UK kitchen and home appliance brand, and this 7-fin radiator is sized right for a small bedroom or nursery rather than a whole living room. At this price it's a sensible backup heater to keep in a spare room, or a first heater for a student flat.
9.
PELONIS Oil Filled Radiator, 3 Heat Settings
Best Features🔥 3 heat settings🌡️ Oil-filled📐 Living rooms, 15-20m²
PELONIS packs three separate heat settings plus a thermostat dial into this radiator, giving you more control over running cost than the single-setting budget units above. Good middle-ground pick if you want to fine-tune output room by room rather than just full-blast or off.
10.
20 Bar Portable Heated Clothes Airer
Best for Laundry🔥 Heated airer🌡️ Laundry drying📐 Indoor drying racks
Not a room heater — a heated clothes airer, and we're including it because it solves the same winter problem from a different angle: drying laundry indoors without cranking a radiator or running a dehumidifier all day. 20 bars of heated rail dry a full load faster and cheaper than either. Pairs well with a dehumidifier on laundry mode — see our 10 Best Dehumidifiers guide for that combo.
