What are external wall insulation grants?

Grants for external wall insulation can be provided under the ECO4 government-backed scheme for eligible UK homeowners.

These programs aim to assist homeowners and landlords in enhancing the energy efficiency of their properties by incorporating insulation into their external walls.

The process of external wall insulation involves fixing insulation boards or alternative materials to the exterior of your home.

This method effectively minimises heat loss, leading to reduced energy bills. The insulation is shielded by a protective layer, such as render or cladding.

You may also be eligible for cavity wall insulation if your property has solid walls.

People who meet the ECO4 eligibility criteria can access grants for external wall insulation. The grant’s availability and amount depend on factors like:

  • The age of your property
  • The location of your property

The government ECO4 grant aims to target low-income households and those in fuel poverty, but it may also be accessible to other homeowners and landlords seeking to enhance the energy efficiency of their properties.

What Is External Wall Insulation?

External wall insulation involves fixing an insulating layer to the exterior walls of your home, which is then coated with a specialized plaster, render, or cladding. Older homes constructed before the 1920s typically feature solid walls instead of cavity walls.

Solid walls tend to allow more heat to escape, compared to cavity walls.

The implementation of external wall insulation helps minimize heat loss through your home’s walls, contributing to lower energy bills.
