What is cavity wall insulation?

Brick-built properties constructed between 1924 and 1982 often feature uninsulated cavities between two layers of brick or between bricks and blocks. These gaps can be filled with cavity wall insulation materials such as mineral wool, polystyrene beads, or polyurethane foam to improve energy efficiency. By filling these spaces, cavity wall insulation helps reduce heat loss through walls by up to 35%.

If your home isn’t suitable for cavity wall insulation, you may qualify for an external wall insulation grant.

How do I know if my house is suitable for cavity wall insulation?

Before applying for an ECO4 cavity wall insulation grant, it’s essential to determine if your home has cavity walls. Properties built with brick from 1924 onwards are likely to have cavity walls. However, if your home was built before 1924, it probably has solid walls. Homes constructed after 1982 should already include cavity wall insulation, as building regulations required insulation installation during construction.

Below you can see examples of the brick patterns for cavity and solid walls.

Cavity Wall

If your home has cavity walls, the bricks are typically in a uniform pattern, with all bricks arranged lengthwise.

Solid Wall

For homes with solid walls, the brick arrangement features an alternating pattern, where some bricks are laid across the wall, exposing their smaller ends on the exterior.
