Energy Saving TrustHome Renewables Selector

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 explore 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:

  • 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.

  • Micro wind turbine

    Wind turbines use the power of the wind to generate electricity. When the wind blows, the blades rotate, driving a turbine that generates electricity.

    Calculate savings

  • Air source heat pump

    An air source heat pump transfers heat from the outside air to water, which heats your rooms via radiators or underfloor heating. It can also heat water stored in a hot water cylinder for your hot taps, showers and baths.

    Calculate savings

  • Biomass boiler

    A biomass boiler burns wood pellets, chips or logs to power central heating and hot water systems.

    Calculate savings

  • District heating

    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.

    Calculate savings

  • 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.

    Calculate savings

  • 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.

    Calculate savings

  • Air-to-air heat pump

    Air-to-air heat pumps use electricity to transfer heat between the inside and outside of your home. They are a low carbon way to heat, and even cool, your home.

    Calculate savings

  • Solar assisted heat pump

    A solar assisted heat pump provides hot water using heat from a panel on your roof. The panel is warmed by direct sunlight and can also collect heat from the surrounding air. The hot water is stored in an insulated hot water cylinder for when you need it.

    Calculate savings

  • Hybrid heat pump

    A hybrid heat pump typically involves an air-source heat pump operating alongside a fossil fuel boiler, with automated switching between the two systems to optimise savings.

    Calculate savings

  • 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.

    Calculate savings

  • Electric 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.

    Calculate savings

  • PV Diverter

    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.
