Home Renewables Selector (beta)
Discover your options, calculate your savings.
Use the Home Renewables Selector to see which technologies could be suitable for your property (in Scotland only). You can also look at specific technologies to see how much carbon and money you could save by installing them.
Generate and download a report that summarises the recommendations and find out what to do next. It will take about two minutes to complete the questions, after which you may wish to spend some time exploring the information provided.
Please note you will be asked about the age and characteristics of your property so make sure you have these details to hand.

If you know what system you are interested in, start exploring here:
Technology used to generate electricity for your property. Excess electricity can be exported to the electricity grid or stored for later use.
Solar photo-voltaic panels
Solar panels, also known as solar photovoltaics (PV), capture the sun's energy and convert it into electricity. Solar panels are usually mounted on top of a roof but systems can also be installed on the ground or as solar roof tiles.
Technology to heat your property and hot water. As well as being more environmentally friendly than fossil fuels, some of these technologies could generate additional payments through the UK government's domestic Renewable Heat Incentive (RHI) scheme.
Air source heat pump
Air source heat pumps absorb heat from the outside air and use it to heat your property and hot water. They can still extract heat when air temperatures are as low as -15°C.
A biomass boiler burns wood pellets, chips or logs to power central heating and hot water systems.
A district or community heating scheme provides heat from a central source to multiple properties or buildings through a network of heat mains (pipes). This removes the need to have your own boiler.
Ground source heat pump
Ground source heat pumps absorb heat from the ground (which stays at a relatively stable temperature year-round) to heat your property and hot water.
Solar hot water panels
Solar hot water systems collect heat from the sun to heat your water. The hot water is stored in a hot water tank or thermal store until you need to use it.
Energy storage systems allow you to capture electricity when it is available (for example, from a solar PV system during the day), and save it until a time when it is useful to you.
Charging an electric vehicle
Electric vehicles (EVs) are fully powered by electricity which is stored in rechargeable batteries within the vehicle. You can use excess generated electricity to charge an electric vehicle or plug-in hybrid at your property.
Storing energy in a household battery
Household batteries store any excess electricity that you generate for later use. For example, if you are out during the day when solar PV panels are generating electricity, a battery could store that generated electricity.
There may be times when your PV system is generating more electricity than your household can use. Instead of exporting that energy to the grid, you could consider installing a PV diverter. A PV diverter uses the surplus energy to power the immersion heater in a hot water cylinder, storing hot water for you to use later. A PV diverter on its own is unlikely to meet all of your hot water needs but it could help to reduce your bills. For more information on PV diverters, see EST’s Solar PV Page.
