Home insulation improves energy efficiency, reduces energy bills, and enhances overall comfort.
Different types of insulation—loft, external wall, internal wall, and cavity wall—suit various property types and address specific energy issues.
Research shows you can make substantial annual savings depending on the type of insulation installed.
Insulation works. Loft, wall, and cavity insulation provides substantial savings by reducing heat loss and maintaining temperatures efficiently. But why so many different types? What’s the difference between them?
It really depends on you. Each type of insulation is suited to different property types and energy needs. Significant annual savings on energy bills can be realised, as shown by the latest Energy Saving Trust research.
Home insulation not only helps in creating a cosy and comfortable living space, but it also significantly cuts down on energy bills. Proper insulation keeps your home warm in the winter and cool in the summer, ensuring that your heating and cooling systems don’t have to work overtime.
So, if you’re wondering how much you could save by insulating your home, let’s look at the different types of insulation, their benefits, and the potential savings you could enjoy.
What is Loft Insulation?
Loft insulation is one of the quickest and most efficient ways to enhance your home’s energy efficiency. Acting like a blanket, it traps heat inside during the winter and blocks heat out in the summer, providing year-round temperature control.
Achieve a cosier, more comfortable home
Save money on your heating bills by reducing energy consumption
Better control over your heating system
The Energy Saving Trust estimates that you can save up to £340 a year* on energy bills by installing loft insulation. This saving varies based on the size and type of your property.

What is External Wall Insulation?
For homes with solid walls, external wall insulation is a robust solution. It adds a layer of insulation to your home’s exterior, acting as a barrier to heat loss and gain.
Keeps your home warm in winter and cool in summer
Reduces the pressure on heating systems, reducing energy bills
Improves carbon footprint
With external wall insulation, you can save up to £500 annually* on energy bills, according to the Energy Saving Trust. The upfront cost depends on the size of the property and the type of insulation used.

What is Internal Wall Insulation?
Internal wall insulation involves adding an insulating layer to the inside walls of your home, reducing heat loss through walls.
Keeps rooms warmer during the colder months
Decreases reliance on heating, reducing energy bills
Provides a warmer, more comfortable environment, reducing risks of illness
The cost of internal wall insulation depends on the number and size of rooms, with potential savings of hundreds of pounds annually, as estimated by the Energy Saving Trust.
What is Cavity Wall Insulation?
Cavity wall insulation fills the gap in cavity walls with an insulating material, reducing heat loss and increasing energy efficiency.
Keeps the home cosy, especially in winter
Reduces energy bills by minimising heating needs
Helps prevent damp and moisture problems
Cavity wall insulation can save up to £370 annually* on energy bills, given a suitable investment based on the property size and nature.

By insulating your home, not only do you create a more comfortable living environment, but you also make a significant impact on reducing your energy bills and carbon footprint.
You could save a considerable amount by insulating your home. Investing in the right insulation is a step toward a more cost-effective and environmentally friendly household. Like any home improvement though, there is of course an upfront installation cost to consider, unless you’re eligible for one of the many energy schemes currently awarding energy efficiency improvements to eligible homes!
