Cavity Wall Insulation in Leeds & West Yorkshire
Fill the gap in your cavity walls to stop heat escaping.
If your home was built between the 1920s and 1990s, it likely has cavity walls — two layers of brick with a gap between them. Filling this cavity with insulation material can significantly reduce heat loss. Around a third of heat lost in an uninsulated home escapes through the walls, making this one of the most impactful upgrades for properties across Leeds and West Yorkshire. The cavity wall insulation cost is typically low relative to the savings, and many households can get free cavity wall insulation through government-backed schemes like ECO4.

Frequently Asked Questions
How do I know if I have cavity walls?
Most homes built between the 1920s and 1990s have cavity walls. You can check by measuring the wall thickness at a window or door — cavity walls are usually more than 260mm thick. A qualified assessor can confirm this for you.
Is cavity wall insulation suitable for all homes?
Not all homes are suitable. Properties with damaged brickwork, exposure to heavy driving rain, or certain construction types may not be appropriate. A proper survey will determine suitability.
Can cavity wall insulation cause damp?
When properly installed in a suitable property, cavity wall insulation should not cause damp. Problems can arise from poor installation or unsuitable properties, which is why a thorough pre-installation survey is essential.
How do I know if my walls are cavity or solid?
The easiest check is wall thickness — measure at a window or doorway. Cavity walls are usually over 260mm (about 10.5 inches) thick, while solid walls are typically around 225mm (9 inches). Most homes built between the 1920s and 1990s have cavity walls. Homes built before 1920, including many stone-built properties in West Yorkshire, are more likely to have solid walls. A qualified surveyor can confirm by drilling a small test hole.
