Great British Insulation Scheme

Save money on your bills by making your home more energy efficient with the newest government funded scheme.

The Great British Insulation Scheme could help you with the cost of installing new home insulation.

What is this scheme?

home

Insulating your home is one of the best things you can do to reduce your energy bills by preventing heat loss from your walls and roof, but it can be a large upfront expense which a lot of people can't afford.

The Great British Insulation Scheme is government funded and designed to help eligible groups of people install insulations in their home, which could save homes around £300 a year on energy bills. The fund aims to help around 300,000 people and could mean free or reduced costs for home insulation.

Unlike other schemes the Great British Insulation Scheme will boost help for those on the lowest incomes as well as support to a wider group of households who live in the least energy efficient homes in the country.


Am I eligible?

There are two groups who can apply for the Great British Insulation Scheme - a general group and a low-income group. The eligibility criteria for each group differ, so read carefully to see whether you qualify.

You don't need to be an Octopus Energy customer to apply for the scheme.

×

Can I pick the insulation I want?

×

The insulation the installer recommends will be based on what will reduce your energy use, rather than your preference.

The installer will perform a survey on your home to determine what home improvement recommendations might be suitable for your home for maximum energy savings.

What type of installation will be offered?

×

Loft or cavity wall insulation is likely to be the most commonly suggested type of upgrade however there are a few more types of insulations we can do. Our installer will need to carry out a home survey first and will suggest the best suited upgrade for your home.

Please be aware that when installing any insulation measure, we will also be installing ventilation to adhere to PAS2035 regulations:

  • Trickle vents will be installed to all windows that don’t currently have any.
  • Mechanical extractor fans will be added to any wet rooms that don’t currently have them (eg kitchen, bathrooms).

This is to prevent the risk of damp building in your property.

Insulation cannot be installed without approved ventilation being carried out.
