Will internal wall insulation reduce my bills?
Installing internal wall insulation will make your property warm and comfortable, reduce your energy bills, lower your carbon footprint, and add value to your home.
Adding internal wall insulation to your home can be a disruptive job, but if external wall insulation isn’t an option then this is the next best way of improving your home’s thermal efficiency.
Many people opt for internal wall insulation if external wall insulation is too costly or if there are restrictions on the work they can do to the outside of their property, for example those in a conservation area or a listed building.
Insulating walls internally is generally slightly less effective than insulating externally but can also be up to 25% cheaper.
What is internal wall insulation?
Internal wall insulation is a method of insulating solid walls internally to increase their thermal efficiency.
This is usually done by building a new stud wall and filling it with insulation. Other methods include affixing rigid insulation boards to the walls, dry lining, and applying flexible thermal lining.
How much will internal wall insulation reduce my energy bills by?
Whilst the job can be costly to complete, it is usually still cheaper than adding external wall insulation and will help to reduce your energy bills by significantly reducing heat loss.
Figures from The Greenage report that about 35% of heat lost from your home escapes through the walls. Uninsulated properties with solid walls are at risk of losing the most heat through their walls.
According to the Energy Saving Trust, after having internal wall insulation installed, the typical annual savings that can be made are as follows:
Detached – £435
Semi-detached – £260
Mid-terrace – £160
Bungalow – £175
Flat – £120
