An energy saving heater in a UK home usually means a plug-in electric heater that heats one room with a thermostat, ECO mode or a lower wattage setting so it is not stuck on full power all day. PTC ceramic fan heaters are common because they warm up quickly and many listings add tip-over and overheat cut-outs. Running cost still tracks kilowatts × hours × your unit rate, so lower settings and heating only the room you use matter as much as the brand. This guide compares heaters sold with energy-efficient, low-energy or ECO wording on Amazon UK, using wattage and mode details from each listing. We found 8 energy saving heaters in stock on Amazon UK with a live buy-box price when we checked on 27 October 2026. Our overall pick is the Dreo 1500W Oscillating PTC Space Heater at £46.69, the budget pick is the CUQOO 2kW Fan and Heater 2-in-1 at £12.99, and our pick for lower wattage is the Timiyou 800/1200W Low Energy Silent Heater at £16.99. Prices and stock change often, so check both on Amazon before you buy.

Buying advice
Our top picks
Best overall: Dreo 1500W Oscillating PTC Space Heater (£46.69). 1500W PTC ceramic heater with 70° oscillation on the title. Listing bullets mention ECO-style control, quick PTC heat and about 40dB quiet running. A compact known-brand pick for a living room or office.
Best budget: CUQOO 2kW Fan and Heater 2-in-1 (£12.99). The cheapest heater here. 2kW fan heater with dual heat settings (1000W/2000W on the bullets) and low-energy wording on the title. Simple dial control for small rooms when you want a low purchase price.
Best lower wattage: Timiyou 800/1200W Low Energy Silent Heater (£16.99). Lower max wattage than most 1500–2000W towers: 800/1200W with thermostat and two modes on the title. Listing claims below 37dB. Suited to a desk or small bedroom where you want less power draw.
Other energy saving heaters worth a look
Igenix IG5200 Low Energy Convector (£19.99). Freestanding convector with adjustable thermostat and three power settings on the listing. Low-energy wording on the title. A quieter-style alternative to a blasting fan heater for longer background heat.
DDHTSAL 900W PTC Ceramic Heater (£23.98). 900W PTC ceramic heater with 45dB quiet claim on the title. Lower wattage than typical 1500W models. Listing describes rapid PTC heat and dual safety protection.
PALINTH 1500W PTC 4 Modes (£30.99). 1500W PTC heater with four modes including ECO and Nature Wind on the listing bullets, plus adjustable temperature. Mid-price everyday room heater.
Ateroll 1500W Quiet Heater ECO Mode (£49.99). 1500W PTC heater with ECO mode named on the title. Listing bullets list High, Low, ECO and Natural Fan modes. Quiet space-heater wording for home use.
QEXREED 2000W PTC Heater ECO Mode (£59.99). 2000W PTC fan heater with ECO mode on the title. Listing describes fast PTC heat and wide coverage. Higher wattage for larger rooms when you need a short boost, then use ECO or thermostat to cut back.
Wattage, ECO mode and your bill
Electric heaters turn almost all the electricity they use into heat at the point of use. A 2kW setting uses about 2kWh per hour while the element is on; a 0.9–1.2kW heater uses less per hour. Cost = kW × hours × the unit rate on your bill.
ECO and thermostat modes on listings such as Dreo, PALINTH, Ateroll and QEXREED are meant to cut power once the room is warm. Use them, and heat only the room you are in, rather than leaving a heater on full all day.
Fan heater, PTC or convector?
Most picks here are PTC ceramic fan heaters for fast warm-up. The Igenix (£19.99) is a convector for steadier background heat. The Timiyou (£16.99) and DDHTSAL (£23.98) keep max watts lower for small spaces.

What to look for in an energy saving heater
Wattage. Lower max watts use less energy per hour; use higher watts only to warm a room quickly.
Thermostat or ECO. Stops the heater running flat-out once the set temperature is reached.
Room size. Match power to the space; oversized heaters waste money if you leave them on high.
Safety. Tip-over and overheat protection are common on these listings; keep heaters clear of soft furnishings.
Noise. Quiet dB claims help in bedrooms; fan heaters are rarely silent on high.
Controls. Remote and timers make it easier to avoid heating an empty room.
How we chose these picks
We only included products that were in stock on Amazon UK with a single live buy-box price in pounds when we checked on 27 October 2026, read with a UK delivery address. We skipped listings showing low stock, no stock line or unclear details, and we avoided repeating products already featured in our other guides. Specs in the comparison table come from each product's Amazon UK listing, and a dash means the listing does not state that detail. Descriptions are based on what each listing says; we have not tested these products ourselves, and we have not used star ratings or review counts.

Frequently asked questions
What is the most energy saving heater?
Among plug-in electrics, the ones that save most on the bill are usually those you can run at a lower wattage with a thermostat or ECO mode, used only in the room you occupy. In this guide that includes lower-watt models such as the Timiyou 800/1200W and DDHTSAL 900W, and 1500W PTC heaters with ECO modes. Running cost is still kW × hours × your unit rate.
Which heater is cheapest to run uk?
For the same hours of use, a lower-wattage setting costs less: roughly 0.9–1.2kWh per hour on the smaller PTC heaters here versus about 2kWh per hour on a 2kW fan heater on full. Multiply by your unit rate. Thermostats and ECO modes reduce the time spent on full power.
What is the most energy efficient heater for a bedroom?
A bedroom usually suits a lower-wattage PTC or a heater with ECO/thermostat so it is not blasting all night. The Timiyou listing emphasises 800/1200W and quiet running; several 1500W models add ECO modes. Keep any heater clear of bedding and never cover it.
