Internal wall insulation cuts energy costs significantly.

Installed to the interior side of your walls, the insulation prevents heat from escaping through your walls, especially if your home is not suitable for cavity wall insulation.

Solid-walled homes, often built pre-1920s, without cavities can install either internal or exterior wall insulation.

Internal wall insulation creates a thermal barrier between the inside and outside of your home, thereby reducing heat loss.

The Energy Saving Trust (EST) estimates that you can save up to £930* per year by installing internal wall insulation.

*The Energy Saving Trust estimate for gas-heated detached homes, October 2022.
