Double Glazing Grants: Are They Available?

Double Glazing Grants

On 8th July 2020, the government announced that Green Homes Grants are available until March 31st 2021. The scheme offers vouchers of up to £5,000 to homeowners (up to £10,000 for the poorest households) to enable them to make energy-saving improvements to their home. Double glazing grants are included in the scheme as a secondary measure, but only available when you apply for a primary measure, e.g. installing insulation or renewable heating.

In this guide, we've outlined the schemes and eligibility requirements available to anyone looking to upgrade their windows with double glazing – including alternatives to double glazing grants.

Green Homes Grants

On 8th July 2020, the government announced that from September 2020 until March 31st 2021, homeowners in England will be offered vouchers of up to £5,000 to carry out energy-saving improvements to their home.

The government is giving out up to £2 billion worth of vouchers called Green Homes Grants in one year. The vouchers will cover up to £5,000 of the cost of installing various types of insulation, a heat pump or solar thermal panels, with up to £10,000 available for the poorest households.

Green Homes Grants will pay for at least two-thirds of the cost of installing insulation or renewable heating. If you take out a grant for one of these primary home improvements, you can also apply for a grant for:

  • Windows and doors: Double/triple glazing (where replacing single glazing), secondary glazing (in addition to single glazing), upgrading to energy efficient doors (where replacing doors installed prior to 2002).

Other measures which are covered by the secondary grant include draught proofing, heating controls and hot water tank insulation.

The value of the secondary windows grant you receive cannot be higher than the value of the primary grant.

When the approved installer has provided a quote and the work has been approved, the Green Homes Grant voucher would be issued.

The scheme is intended to help homeowners to reduce their heating bills and carbon emissions through improved insulation, i.e. reduced heat loss. The scheme should launch in September 2020 with an online application process and is due to close in March 2022.

Green Deal Grant No Longer Available

The Green Deal was the biggest support grant available for anyone looking to install double glazing, however the scheme was closed in 2015. This was a government funded initiative that entitled homeowners to loans of up to £7,600.

These loans were paid back via the savings being made on the quarterly energy bill, effectively making the double glazing installation 'free'.

Now that the scheme has closed, and won't be making a reappearance, any homeowners looking for support with financing double glazing need to look elsewhere. To make things easier for you, we've done the research to help you find a scheme that works for you and your home.
