How Eco-Friendly Home Insulation Can Cut Your Energy Bill

With a push for energy initiatives and a focus on renewable energy, the UK and Scottish governments are pushing for homes to become more efficient. As a result, they have set up multiple schemes and grants for eligible individuals that can help them improve their homes and save on their energy and heating bills. And, if you meet the necessary criteria, you can be part of these initiatives as well!

These programmes can help you to save a lot of money on your bills. But, if you’re wondering exactly how much you could be saving every year with eco-friendly home insulation, we’re here to help. So, let’s get ready to save on energy costs and make your home more efficient than ever.

How Much Could You Save by Insulating Your Home?

The amount of money you could save by insulating your home is directly dependent on which improvements you have installed in your home. For instance, having both wall and loft insulation installed will result in a much bigger saving than only having your loft insulated. This means that the more you improve your home, the bigger your savings could be.

Generally, you may be able to save between £50 and £620 every year for a single improvement. However, you may be able to save as much as £1,625 per year if your home is fully insulated (more on this below).

The Advantages of Sufficient Insulation

Besides the government’s programmes and incentives that provide financial support for you to improve your home, there are tons of advantages and benefits to insulating your home. Some of the most obvious advantages of insulating your home include:

  • Eco-friendly: Better energy efficiency means fewer carbon emissions and a smaller carbon footprint. This helps to contribute to the UK’s efforts to improve the lives of its residents through better energy efficiency measures.
  • Comfort: Home improvements like insulation can help to regulate your home’s indoor temperatures, keeping you cool in the summer months and warm and snug during the cold Scottish winters.
  • Home value: Homes that have already installed energy efficiency improvements have a higher resale value than homes that don’t.
  • Lower energy bills: The biggest advantage of undertaking energy efficiency upgrades in your home is reaping the benefits of lower energy bills.

Cavity Wall Insulation Potential Savings

Getting cavity wall insulation installed is a great (and cost-effective) way to reduce the amount of heat loss in your home. This is particularly true if you live in a home that was built after the 1920s and has cavity walls.

By injecting insulation material into the wall cavity (the gap between the inner and outer walls), you can potentially save between £125 and £455 per year.

Loft Insultations Potential Savings

Did you know that your home can lose heat through the roof and your lofts? Well, loft insulation is a great way to counteract this problem and regulate your home’s temperature.
Depending on the size of your home, you can actually save around £225 – £415 (for a gas-heated home) with loft insulation. Additionally, if you’re committed to home energy efficiency and have more than one energy-saving improvement installed, this only helps to further knock down the cost of your heating bills.

Floor Insulation Potential Savings

Insulating the ground floor of your home is another important step in improving your home to be more energy efficient. If your home has suspended floors, insulation underneath the floorboards can help to save you around £50 – £135 a year.
It may be important to note that solid concrete floors can also be insulated if they’re replaced or if they’re covered with rigid insulation. However, this can be costlier than regular floor insulation and may not be covered by the insulation scheme you’re using to improve your home.

Internal Wall Insulation Potential Savings

An internal or solid wall refers to the walls inside of your home that separate the different rooms. These walls don’t typically have a gap or cavity, which also means that they can be more costly to insulate.

Generally, the insulation of an internal wall can cost as much as £7,500. Still, depending on the insulation scheme you choose, you can save significantly on the installation costs or receive an interest-free loan.

After insulation installation, you can expect to save roughly £170 – £620 per year. Combined with other insulation methods and depending on your home’s size, this can contribute to huge savings every year!

Are There Grants for Home Insultation?

There are several insulation grants that you could get in Scotland. Some of these grants include:

  • Warmer Homes Scotland Scheme
  • Home Energy Scotland Loan
  • Renewable Heat Incentive

Perhaps the most prevalent insulation scheme at the moment is the ECO4, or Energy Company Obligation, insulation scheme. This is a government-backed programme that was created to improve the energy-saving efforts of local homes and reduce carbon emissions within the UK.


Although some insulation can be installed without the help of a professional (such as loft insulation), this may prevent you from receiving any of the grant benefits that are available.

Most of the grants or loans available require that a professional or team of professionals evaluate your home and schedule the instalments of any improvements they deem necessary.

According to the Energy Savings Trust, having loft insulation in your home can save you up £250 annually, depending on the size of your home. With other energy efficiency methods, like roof and wall insulation, you can increase these savings.

Final Thoughts

If you’re ready to start saving, then you’ll want to start by checking the eligibility criteria for the scheme that you want to use. From there, you can start the process of improving your home and saving money on your monthly bills.
