Before you start

Before comparing quotes, consider your budget, home aesthetics and the number of radiators you need to heat your home comfortably. Modern electrical radiators have a slimline form factor, making them an ideal solution for narrow rooms and hallways. And they're virtually silent in operation, using an electric heating element to generate warmth.

How do electric radiators work?

Before we dive into the details, let’s recap how electric radiators work. Each unit houses a thermodynamic liquid or ceramic block. When heated, the fluid expands and radiates heat, which then circulates as warm air. Once the desired temperature is achieved, the radiator switches off until the temperature drops. Electrical radiators in the UK are fitted with internal thermostats that automatically detect the most efficient heating mode, saving you money. 


Alternatively, your electrical radiators can be operated with a smart valve and thermostat setup, allowing you to create highly efficient and cost-effective heating zones.

Are electric radiators worth it?

There are plenty of benefits to installing wall-mounted electric radiators in your home. They're highly efficient and low maintenance. With no moving parts, they're less likely to develop a fault and won't need bleeding or draining to ensure they work efficiently. 


Electrical radiators heat much more rapidly than a gas-fire central heating system for almost instant warmth. And with a zoned heating system, you can keep bedrooms and less well-used rooms at a lower temperature to reduce your running costs further.

What price can I expect to pay for electric radiators in the UK?

The cost of electric radiators varies depending on the output in kWs, the design aesthetic and the additional features. You can expect to pay more for designer radiators with features like smart self-programming technology or voice assistant support. 


Bear in mind that the size of your rooms and the level of insulation in your home will also impact the wattage of the radiators you need. For example, depending on your home's insulation level, you'll need to allow 70-100 watts per square metre to match your heating requirements. For larger spaces, aim to use two or more radiators that match the correct heat output.

What is the life expectancy of electric radiators?

Electrical radiators are a reliable, durable and high-quality heating solution. There are no moving parts, and your system won't need to be drained down or regularly serviced. You can expect your radiators to work efficiently for up to 15 years.

What different styles of electric radiators are available?

Modern electric radiators in the UK offer a boundless choice of designs, from retro stylings to contemporary slimline panels. With no pipework required, electrical radiators are often a plug-and-play option. Despite their simplicity, it's always best to work with a trained professional, who can ensure the electric safety of your radiators and home. This will ensure your home stays insured and you can sell your home with ease.

Now, let’s compare electric radiators.

Convection Radiators

In a convection radiator, cool air enters the bottom of the radiator. This air is then heated by an electric element, becoming lighter and rising through the top of the panel. As it cools, it sinks back to the bottom, and the process begins again, creating a warm and cosy atmosphere.

Infrared or radiant radiators

These radiators gently diffuse heat into the room via infrared radiation. Because these radiators heat objects and people rather than the radiator itself, the panel remains cool to the touch. Infrared radiators can look like pieces of art, keeping your home stylish.

Wall-mounted radiators

A popular choice offering precise control over your heating while requiring no maintenance. A versatile choice known for being fuss-free, this easy option comes in a wide range of sizes and designs to suit any interior, giving these radiators a sleek aesthetic appeal.

Inertia radiators

Most modern radiators use inertia technology to create heat.


  • Thermal fluid radiators use thermodynamic oil to create a steady heat spread throughout the radiator. Due to the oil-filled columns, these radiators often have a quirky vintage design aesthetic.

  • Dry thermal radiators rely on fast heating and lightweight, dry heating elements to create warmth. And they're a practical option for most homes.

  • Dry stone radiators are ideal for larger, hard-to-heat spaces. The ceramic heating element takes longer to heat but has greater retentive properties for longer-lasting warmth.

How efficient are electric radiators?

Electric radiators are 100% efficient, making them a viable alternative to conventional water-filled radiators. There's no waste with electrical radiators, which compared to traditional hydronic or water-filled radiators, makes an energy saving of up to 40%. 


But how much do electric radiators cost to run? Electricity is currently more expensive per kilowatt than gas. However, as gas needs more energy to turn into heat, the overall costs to run an electric heating system can be lower than gas. In addition, costs are expected to fall as the UK transitions to clean, sustainable energy. To work out your electricity usage per hour, look for the size of the radiator. For example, a 1000W radiator uses 1kW of electricity per hour. Multiply this figure across the number of radiators in your home to calculate your total energy use.


If you want to make your system more sustainable, pair your radiators with a sustainable energy source like solar panels. As a result, the entire system is carbon-neutral and energy-efficient from end to end. Your solar panels may even make your radiators free!

Using electric radiators to save money on energy bills

If you want to get the best out of your new electric heating system, look for the following features:


  • Precision digital thermostats will adjust the temperature in your room automatically so the space is heated to the correct temperature. You won’t need to regulate the temperature manually, and it’s easy to set up zoned heating, so you’re not paying to send hot water to a radiator in a room you don’t need to heat.


  • Open window detection ensures your radiator automatically shuts off if you've left a window open. Then, when the window is closed, the radiator establishes the correct ambient temperature. 

  • Voice and Wi-Fi controls give you total control over every aspect of your home heating. It's easy to set up heating zones and daily or weekly schedules to maximise the use of cheap electricity or reduce the temperature in rooms you rarely use.

How much do electric radiators cost to run per hour?

According to official figures, the average price for 1kW of electricity in the UK is currently 30p. This simple calculation will help you estimate your running costs:


Radiator output in kW (1000W = 1kW) x Price per kW x hours of use = running cost 


So a 500W radiator would cost an average of 15p an hour to use.


Of course, there's no one-size-fits-all measure. For example, a cheaper electricity tariff or using solar energy will have an impact. Insulation is another critical factor in keeping your bills down, as is investing in radiators with a range of smart features to give you complete control over different heating zones in your home.
