Solar Heating Grants

Grants for Installation of Domestic Solar Hot Water Systems by Accredited Engineers

Under the Low Carbon Building Scheme the UK Government provides a grant to home-owners (amongst others) who want to install microgeneration technologies, including solar hot water systems.

Homeowners can apply for a grant of up to £400 to assist in the cost of installing a solar panel hot water system. The system must be installed by an accredited installer and the system must include approved solar products. You must apply for the grant before installation commences.

Requirements to make a Grant Application for a Solar Water Heating System

Your home should be as energy efficient as possible before you consider investing in solar hot water systems.

To qualify for the grant, you will be required to demonstrate that you have installed a basic level of energy efficient measures and you should endeavour to minimise your energy usage as much as practical before applying for the grant.

Before applying for a grant for a solar hot water system you are required you to have:

  • insulated the whole of the loft of the property to meet current building regulations e.g. 270mm of mineral wool loft insulation or suitable alternative
  • installed cavity wall insulation (if you have cavity walls)
  • fitted low energy light bulbs in all appropriate light fittings
  • installed basic controls for your heating system to include a room thermostat and a programmer or timer.


You must obtain a quote from an accredited installer before applying for the grant.
