100% efficient heating

Electric Panel Radiators

Cleaner, more efficient heating for your home powered by over 90% renewable energy. This ‘dry’ heating system won't need a boiler as each radiator has its own heating elements and electric circuit supplying the power.

Say goodbye to your boiler and wet radiator system. With electric radiators installed throughout your home, you can heat individual rooms using the programmer/thermostat to just the right temperature. A cosy lounge at 21°C while the spare room at 12°C keeps damp at bay

  • Smart and stylish

    Heating doesn't have to just be a white radiator. Panel radiators come in a fantastic range of colours and textures, from bright red through to yellow, and even marble-effect. There are shapes and sizes to suit every room, with many WiFi enabled so controllable from your smart phone.

  • Practically 100% Efficiency

    This means every £1 you spend on electricity will give you £1 worth of heat for your home. A new gas or oil boiler will always be less than 100% efficient and will become even less efficient as they age.

  • Zero harmful emissions

    Meaning the air both inside and outside of your home is cleaner. And as over 90% of Guernsey’s electricity is imported renewable energy, it is more environmentally friendly than gas, oil or solid fuel from start to finish. 

Top Tip

Don’t wait for your boiler to break midwinter to make the change.
Spring and Summer are the best time to make the switch. As with a house extension or roof replacement, it takes time but is worthwhile.


Power Supply

It’s really important to plan ahead and check if your property needs an electricity supply line cable upgrade. 

Electricity is delivered to your door through an underground network of cables. Some properties don’t have enough capacity in the existing supply line cable to power your new heating system and will need an upgrade.  

Your installer will check this with Guernsey Electricity by submitting an additional load application normally done after you've accepted your preferred installer's heating quote.

Frequently asked questions

Making the switch to electric heating is a fantastic investment for your property. Like any property upgrade, the installation will take time to complete and we want to help answer your questions before you make the decision to change.

No - unless you are replacing an existing electric heating system. However, your preferred installer will always do their best to provide a solution in an emergency. 

Installation timeline

Switching to an electric system is a positive development for your property and similar to other property improvements such as extensions and roof renovations, it will take time to complete. 

Lead times will vary depending on workload and availability, and it is worth preparing for your switch to electric heating well in advance. Please be aware that your property may need a supply line cable upgrade which will add to the timeframe.

We also recommend switching during the spring and summer months when possible so the work can be carried out when you do not need to use the heating. Depending on the work required, it may take several weeks from start to finish.  

We recommend checking current prices and tariffs online first.

Heating systems replace the volume of heat lost from your property, which means property insulation is the most effective way to reduce the running costs of any heating system. 

Electric Boilers and Underfloor Heating

These run on the Superheat Tariff. An electric boiler will cost the average customer in Guernsey roughly 30% less to run than a gas boiler. 

Oil is one of the cheapest commodities and although oil heating systems may initially have a lower running cost when new at around 91% efficiency, over time the cost to run your oil heating will increase as the efficiency decreases.  

Some customers have replaced oil boilers working at less than 70% efficiency, meaning over 30% of their bill was used to pay for waste greenhouse gas emissions rather than valuable heat for their home.

Air Source Heat Pumps

This is the least expensive way to heat a property. 

Unlike other heating systems, air source heat pumps provide three times as much energy as is put in. This means that for every £1 spent on electricity to run the heat pump, you could generate £3 worth of heat for your property. 

Electric heat pumps are much cheaper to run than traditional electric, gas or oil heating systems and run on the Heat Pump Tariff. 

Storage Heaters

These systems run overnight on a customer's off-peak Super Economy 12 Tariff and are the most cost-effective way to run a traditional electric heating system. 

If you’d like to make the switch to a electric heating but are unsure about the upfront cost, we can help spread the cost of your home heating affordably – just complete a short form and we’ll do the rest.  

Some customers have paid as little as £46 a month for their new electric heating system through our finance partner Cherry Godfrey Finance Limited.


There will be a different answer to this question for each property depending on:

  • the network infrastructure in your area
  • the supply line cable connecting your property to the network, and;
  • how much electricity other properties around you are using 

Your neighbour may be in a different position to you if, for example, they had electric heating installed a few years ago, or the network serving their property is from a different substation. 

Your installer will submit an Additional Load Form to Guernsey Electricity's new connections team to establish if there is enough power in the surrounding cable network to power an electric heating system in your property.   

Replacing your gas or oil boiler whilst retaining your existing radiators is the quickest and most simple option. This is known as a ‘wet system’ as it relies on water heated by electricity to be pumped around the property. 

Moving to electric radiators is known as a ‘dry’ system.

This doesn’t need a boiler and all existing radiators linked by pipework can be removed. Electric radiators are then installed throughout the home with a cable supplying each radiator to power it individually. This means each radiator is powered independently and has its own programmer and thermostat.  

The main benefits of a dry electric heating system are:

  • no water pumped around the property which reduces the risk of leaks. 
  • if one radiator fails, the others will still work unlike a wet system where if the boiler fails, there is no heat for the home. 
  • each room can have accurate temperature control e.g. your lounge can be warm and cosy at 21°C, and the spare room can be as low as 12°C just to keep it aired. 

If the supply line cable supplying your property has sufficient capacity, you will not need an upgrade. However to find this out, your installer will need to submit an 'additional load' application. 

If it is needed, often a supply line cable upgrade is either low cost or free of charge. 
The reason customers need to accept their heating installation quote first is to confirm with their installer that they still want to switch to electric heating based on the cost quoted, as it's common to request quotes from different installers for one job. This ensures only the chosen installer makes a single application to Guernsey Electricity for the additional electricity load required, rather than multiple applications for one job. This helps to make sure network capacity is available for other people who might need it.
If a supply line upgrade is required and it happens to involve a cost, the customer can accept or decline the supply line upgrade quote. If they do decline, then the installer cannot proceed with the installation of the electric heating and the customer is not liable for any costs.
