The Green Homes Grant scheme was first published on the 28th August 2020 and was scheduled to end on 31st March 2021. On the 18th November this was extended by a full year due to Covid-19. This initiative via a voucher scheme, allows house owners to reclaim up to two thirds of the costs of improvements on their house, up to a maximum government contribution of £5k. For those on certain benefits, this ceiling level extends to £10k, which is meant to cover the entire cost. Only certain upgrades are eligible, which are linked to installing energy efficient improvements, that reduce energy use and carbon emissions.

These improvements are split into “Primary” and Secondary” measures. Examples for Primary measures are insulation (solid wall; underfloor; cavity; pitched or flat roof), and Low Carbon Heat Sources (for example air source or ground source heat pumps; solar; biomass and hybrid systems).
Secondary measures include, replacing or upgrading windows to double or triple glazed, and upgrading heating controls. Secondary measures can also include insulation, as long as a Primary measure has also been specified.

A voucher is issued for each of the different projects you have applied for, and once completed, your installer must supply you with the energy certification documents, along with an invoice and guarantee documentation, and the MSC certificate where applicable. When you redeem your voucher, the grant will be paid on your behalf, directly to the installer.
