The Green Homes Grant Scheme and Ventilation

What is the Green Homes Grant Scheme?

The Green Homes Grant Scheme is designed for homeowners and landlords to introduce energy saving measures into their homes such as wall, under floor, cavity wall or roof insulation, heat pumps or solar thermal.

Homeowners in England, including landlords, can get up to £5,000 to pay part of the cost of energy saving measures and low income households can get 100% of the costs of work covered up to £10,000.

Households can save up to £600 a year on energy bills by applying today. Installing energy efficient home improvements also cuts emissions, which is better for the environment.

How Does It Work & How Do I Apply?

How does it work?

The government will provide a voucher up to £5,000 that covers up to two-thirds of the cost of the energy efficiency and low carbon heat improvements.

Ventilation and the Green Homes Grant Scheme

It is a legal requirement that the indoor air quality of a home must not be made worse by adding insulation, double glazing or draught-proofing measures under the Green Homes Grant scheme.

PAS 2030 states that the following is required: “Provision of deliberate ventilation sufficient to ensure adequate internal air quality and minimise internal surface condensation risk, especially where the air-tightness of the building envelope will be improved by the installation of insulation, draught stripping, new windows or any other measure”.

By implementing energy efficient improvements, they can increase the airtightness of a home and have a negative effect on the ventilation of the building.

Government guidance on the scheme makes it clear that subsidy received by consumers in the form of the Green Homes Grant voucher can be used to cover “reasonable enabling work to support the retrofit.” A specific item listed in this guidance is repairing and improving controlled ventilation. This means that the provision of ventilation alongside insulation can form part of the grant.
