Improve The Energy
Efficiency Of Your Property

Cavity wall insulation is a proven method to improve your home’s energy efficiency by filling the gap (or “cavity”) between the inner and outer walls of your property with insulating material. This prevents heat from escaping through the walls, helping your home stay warmer for longer.

Most properties built after the 1920s have cavity walls, and if they’re not insulated, you could be losing up to a third of your heat through them. By professionally insulating these cavities, you’ll use less energy to heat your home — which can result in savings of up to 35% on your heating bills.

Not only does cavity wall insulation lower your energy costs, but it also helps reduce your carbon footprint, keeps your home more comfortable year-round, and may even add value to your property.

Reasons to Choose Cavity Wall Insulation

Cavity wall insulation is one of the most cost-effective ways to make your home warmer, more energy-efficient, and cheaper to run. Here’s why it’s a smart investment:

  • Lower Energy Bills – Reduce heat loss through your walls and save up to 35% on heating costs.
  • Improved Comfort – Enjoy a warmer home in winter and a cooler one in summer.
  • Quick Installation – The process is fast, non-intrusive, and usually completed within a day.

FAQ’s

Some of the most frequent questions we get asked.

Cavity wall insulation helps prevent heat loss through your walls, which can account for up to 33% of your home’s total heat loss. By insulating, you’ll improve comfort, cut down on energy use, and reduce your heating bills.

Yes – properly installed insulation can save you up to 35% on your annual heating costs, depending on your home’s size and current energy efficiency.

Most UK homes built between 1920 and 1990 have cavity walls. If your external walls are made of brick and the pattern alternates between long and short bricks, it’s likely you have solid walls. Regular brickwork usually indicates cavity walls.

Not at all. Installation is done from the outside of your home. Small holes are drilled into the exterior wall, insulation is injected, and the holes are filled with matching mortar – all with minimal mess or disturbance.
