There are many simple yet effective ways to insulate your home, which can significantly reduce heat loss while lowering your heating bills. We are able to install Free Cavity Wall, Loft and Room in Roof insulation under the ECO Funding Scheme.

Cavity Wall Insulation

About 35% of all heat loss from UK homes takes place through external walls. Most modern homes have twin exterior walls with a narrow cavity between them.

This can be filled with an insulating material by injecting foam or beads into the wall. This restricts any warmth passing between them, reducing the money you spend on heating.

Benefits of free cavity wall insulation

Cavity wall insulation will prevent up to 35% of heat escaping through your walls. In monetary terms, you could be looking at savings of up to £145 a year for heating a typical family home.


In focus…

  • Cheaper energy bills

  • Helping the environment
  • Quick and easy to install
  • Improved thermal comfort all year round

Loft Insulation

A quarter of heat is lost through the roof in an uninsulated home. In 2003 in the UK, the energy we used in our homes produced 27 per cent of the carbon dioxide emissions entering the atmosphere.

A typical property could save up to £240 and almost a tonne of Co² each year and with energy bills continuously rising, your savings will only increase with time.

Benefits of 100% free loft insulation

Heat rises, so loft insulation traps heat inside your home. It keeps your home warmer when the weather is cold. It also stops heat coming through the roof when the weather warms up, which means your home will stay cooler.
