Simple to installPowered directly by a cable supply, these provide heat almost instantly and are plugged into their own plug sockets. This means that each one can be set to do a different job in the house independently using its own programmer and thermostat.

100% EfficientThis 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 emissionsElectric heating generates no harmful emissions from a property, 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 from start to finish.
Overnight electricity is less than half price for most customers on an Economy 12 tariff. Storage heaters are clever systems that use low-rate electricity to generate heat which is then absorbed by in-built materials that stores the heat until you need it.
The heaters use high levels of insulation material to keep as much heat as possible in so the heat can be gradually released into the room as it's needed. In the case of smart fan-assisted models, almost all of the heat is retained until it is required.
Modern insultation means that this stoed heat can then be released in a controlled way to heat a room during the day as it's needed.
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.

Step 2Once you have accepted your quote, an 'Additional Load' application will be submitted, which is a process to check if the incoming electricity supply and surrounding network is substantial enough for the additional electricity ‘load’ needed to power your heating system.

NotePlease be aware that the installation process will take time and we encourage you to review the timeframe guideline linked below for an idea.
Power Supply
It’s really important to plan ahead and check if your property needs a service upgrade.
Electricity is delivered to your door through an underground network of cables. Some properties don’t have enough capacity in the existing service cable to supply a new heating system and will need a service upgrade.
Your installer can check with Guernsey Electricity by submitting an additional load application if your property needs a cable upgrade
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.
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 in advance.
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. Insulating a property is the most effective way to reduce the running costs of any heating system.
Electric Boilers
An electric boiler will cost the average customer in Guernsey roughly 30% less to run than a gas boiler.
Oil is one of the most cheapest commodities and although heating oil may initially have a lower running cost when new at around 91% efficiency, over time the cost to run 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 cheapest way to heat your home as you pay for 1kW of electricity to provide 3kW of heat. For example if you paid £100 to heat your home using a traditional electric heating system on the Superheat tariff, this could now cost you £33 to heat the same room (depending on your property insulation).
As gas costs roughly 30% more than traditional electric heating, heat pumps are far cheaper to run. And they even cost less to run than oil heating systems.
Storage Heaters
These systems run overnight on a customer's off-peak Economy 12 tariff and are the cheapest 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.
We’re able to offer a generous solution through our finance partner Cherry Godfrey Finance Limited. Depending on the size and type of heating solution you choose, this may include a subsidy from Guernsey Electricity.
There will be a different answer to this question for each property depending on the network infrastructure in your area 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.
Your installer will submit an ‘Additional Load Form’ to Guernsey Electricity to establish if there is enough power in the surrounding cable network to power your electric heating system.
Replacing your gas or oil boiler is the quickest and most simple option and is known as a ‘wet system’ as it relies on water heated by electricity to be pumped around the system.
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.
