Renewable Energy Heating

Frequently Asked Questions


How Do Heat Pumps Work?

Heat pumps are an energy-efficient way for you to heat your home while saving money.
These installations circulate refrigerant through evaporation and condensation, providing heat and recycled energy that can be re-used to heat the home.
It’s much more effective, affordable, and sustainable than traditional heating systems!


The efficiency of an air source heat pump is measured by the Coefficient of Performance (COP). This refers to the maximum efficiency with which the heat pump can run. Most air source heat pumps have a COP between 2 to 4, but in some cases, it can be as high as 5.


The COP refers to how many kilowatts of heat 1 kilowatt of electricity can produce. An air source heat pump with a COP of 4 will produce 4 kilowatts of heat. Meaning the heat pump will provide you with four times more heat than if you would heat your home using electricity.


How Do Solar Thermal Panels Work?

Using Solar Thermal Panels, a thermal system collects heat from the sun and uses it to heat the water used in your home. This is then stored in a hot-water container and circulated around the home, as required.

Solar thermal panels can be used for space heating, but most commonly they provide the
domestic hot water (DHW) needs of households.


Photovoltaic (PV) systems are commonly used solar panel systems in the UK. 
Photovoltaic systems convert sunlight directly into electricity. 


What Are The Benefits of Underfloor Heating?

One of the primary benefits of underfloor heating, is that it keeps rooms at a good temperature while still being energy efficient. While traditional radiators need to be turned up high to achieve this, you can leave your underfloor heating at a more appropriate level without worrying about a chill creeping in.
It’s also easy to install, it requires virtually no maintenance, and there are designs to suit every home.

What Are The Benefits of Renewable Energy?

Lots of the benefits of renewable energy are external, meaning that you’re doing something selfless while improving your home. Pollution is greatly reduced when you choose green products and it also generates good, sustainable jobs! Also, you often see a reduction in monthly bills as lots of the energy is re-used and re-diverted to meet the needs of your home!

Planning & Advice

As heat pumps usually fall into the category of favourable renewable energy, often there is no need for planning permissions. However, there are some exceptions to this rule.


Permissions for GSHPs
If you live in a conservation area or a listed building, contact your local council to make sure that all requirements are met before installing a GSHP.


Permissions for ASHPs

The heat pump must be built according to MCS planning standards.
Any additional ASHPs, wind turbines, etc. on the property require additional planning permission.
The device has to be more than 1 meter from the property boundary.
The device cannot be installed on a pitched roof.

Also, it should not be near the edge of a flat roof.
Conservation areas, world heritage sites, etc. require additional criteria to be met.

Permission for Solar Panels

In England, Scotland, and Wales, you are not required to apply for any planning permissions for most domestic solar panel installations — for both PV and heating installations.

There are, however, restrictions on installations of certain sizes.

If your solar panels protrude more than 200mm from your roof,

you will need to apply for permission first.


In addition, for all installations, if your building is within a conservation area, you will need to adhere to some planning permission guidelines.


Government Grants & Funding

The Government have provided Renewable Heating Incentives for various areas throughout the UK & Ireland.


Boiler Upgrade Scheme 

Launched in April 2022, The Boiler Upgrade Scheme will provide upfront capital grants to support the installation of heat pumps, and in some circumstances biomass boilers.

offering homeowners £5000 voucher deduction towards a heat pump installation.
