Claim 66% off with the Green Homes Grant and save up to £280 a year on energy bills(1) with cavity wall insulation that stops 33% of heat from escaping.
from £600 £204
Cavity wall insulation is one of the best and most affordable things you can do to improve your home's energy efficiency.
For a typical home, cavity wall insulation starts from £204 with the Green Homes Grant.
The Green Homes Grant means you could get two-thirds off the cost, so there's never been a better time to consider it.
Houses in the UK mostly have either cavity walls or solid walls:
Cavity walls can be insulated by injecting insulation into the cavity from the outside through drill holes in the outside walls.
Insulation is usually mineral wool or polystyrene beads or polyurethane foam.
There are some common ways to tell if your property has a cavity wall:
Insulating the cavity space between the outside and inside wall adds a barrier to stop the cold from coming in and heat from escaping.
I have noticed a huge difference in the warmth of my home. Before I was having the heating on not just high during the day but also I had to keep it on through the evening during very cold winter nights. This was extremely expensive.
The UK government has introduced a new grant that allows you to save two-thirds of the cost of some energy-efficient home improvements up to the value of £5,000, or the full cost up to £10,000 if you're in receipt of certain benefits. Act now - the deadline for completion of home improvements is 31 March 2022.
The long-running Energy Company Obligation (ECO) scheme helps people on certain benefits to cut their energy costs through home improvements. The benefits covered are different from the Green Homes Grant, so it's worth checking to see if you qualify.
Cold doesn't just come in through walls, doors and windows, it can come up through the floor too. Insulation can prevent this, make the floor more comfortable to walk on and prevent mould.
Conservatories are often considered a room used in summer but with proper insulation, it could be used all year round.
Get into the details of how insulation can save you money, energy and CO2 emissions, and what different types of insulation there are out there and the materials used.
