An oil filled radiator is a plug-in heater that warms sealed oil inside metal fins, so it gives a steady, quiet heat and stays warm for a while after it switches off. That makes it a popular choice for bedrooms, home offices and rooms the central heating does not reach. The main things to compare are the maximum power, how many heat settings you get, whether there is a timer and what room size the maker suggests. This guide puts those side by side, using only what each Amazon UK listing says, and covers 2kW and 1.5kW models for typical rooms, 2.5kW models with 24-hour timers and a small 500W De'Longhi for a box room. If you want to heat a conservatory, see our separate oil filled radiator for conservatory guide. We found 8 oil filled radiators in stock on Amazon UK with a live buy-box price when we checked on 27 October 2026. Our overall pick is the Russell Hobbs 2kW Oil Filled Radiator, 9 Fin, White at £52.00, the budget pick is the Russell Hobbs 1.5kW Oil Filled Radiator, 7 Fin, White at £39.00, and our pick with a timer is the NETTA 2500W Oil Filled Radiator with 24H Timer, Grey at £69.99. Prices and stock change often, so check both on Amazon before you buy.

How much does an oil filled radiator cost to run?
Running cost depends on the heater's power and how long it runs. Multiply the power in kilowatts by the hours of use to get kilowatt hours (kWh), then multiply by the unit rate on your electricity bill. For example, a 2kW radiator running flat out for one hour uses 2kWh; a 1.5kW radiator uses 1.5kWh. A thermostat cuts the heater in and out once the room is warm, so real use is often lower than the maximum.
A timer, like the ones on the NETTA (£69.99), VonHaus (£79.99) and Pro Breeze (£84.99) radiators, helps you avoid heating an empty room.
What to look for in an oil filled radiator
Power and room size. Russell Hobbs suggests about 15 square metres for its 1.5kW model and 20 square metres for its 2kW model. Higher power heats a room faster but uses more electricity per hour.
Heat settings and thermostat. Several settings plus a thermostat let you run the radiator on lower power once the room is warm.
Timer. A 24-hour timer lets you warm a room before you get up or switch the heater off after you leave.
Safety features. Look for tip-over and overheat protection on the listing. All the 2kW and larger radiators here list tip-over protection.
Fins. More fins give more surface area to release heat, which is why the 2.5kW models have 11 fins.
Cable and castors. Most models have castors; check the cable length if your socket is far from where you want the heater.
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
Which oil filled radiator is best?
For most rooms, a 2kW model with a thermostat, such as the Russell Hobbs 2kW 9 fin radiator (£52.00), is a good balance of power and price. If you want a timer, the NETTA 2500W (£69.99) has a built-in 24-hour timer, and the Russell Hobbs 1.5kW model (£39.00) is the cheapest here.
How much do oil filled radiators cost to run?
Multiply the heater's power in kW by the hours it runs and by your electricity unit rate. A 2kW radiator on full power for an hour uses 2kWh, so at your unit rate per kWh that is the cost of one hour on full. The thermostat switches the heater off once the room is warm, so actual use is usually lower.
What size oil filled radiator do I need?
Check the room size on the listing. Russell Hobbs suggests its 1.5kW radiator for about 15 square metres and its 2kW radiator for about 20 square metres; NETTA and Daewoo describe their 2kW to 2.5kW models as suitable for medium to large rooms.
Is an oil filled radiator cheaper to run than a fan heater?
Not per hour at the same power. Every plug-in electric heater turns electricity into heat, so a 2kW oil filled radiator and a 2kW fan heater use the same 2kWh in an hour on full. Fan heaters warm a room faster; oil filled radiators give a steadier heat and stay warm for a while after switching off.
