Get free* insulation with the Great British Insulation Scheme

Are you a homeowner or private renter looking to save money by becoming more energy efficient? The Great British Insulation Scheme (GBIS) will do just that by installing free* cavity wall insulation, helping you to save an average yearly energy cost of £2351. Savings are based on a semi-detached house, and eligibility criteria will apply.

*To qualify for free insulation, you'll need to own your own home, and your council tax band is between A and E with an EPC rating of D or lower. Or your home has an EPC rating of D or lower, and either you or someone you live with is in receipt of one of the listed benefits below. If scaffolding is required to install CWI, there could be a cost, but we'll let you know before you decide to go ahead.

First time loft insulation

Alternately, you could save £2252 a year by having free first-time loft insulation installed. If you already have a layer of loft insulation, you can still benefit from a top up under the scheme, but you will need to pay a contribution. Savings are based on a semi-detached house, and eligibility criteria will apply.

What's the eligibility criteria for GBIS?

You'll need to meet the following eligibility criteria to benefit from full or partial funding:

  • You're on qualifying benefits, and you are a homeowner with an EPC of D to G.
  • Or you privately rent your home and have an EPC of D or E. 
  • Or you are a homeowner and have an EPC rating of D or lower and a council tax band of A to D in England and A to E in both Wales and Scotland.

Qualifying benefits:

  • Income based Job Seekers Allowance
  • Income related Employment and Support Allowance (ESA)
  • Income Support
  • Pension Credit
  • Guarantee Credit
  • Working Tax Credit
  • Child Tax Credit
  • Universal Credit
  • Housing Benefit

If you qualify through our online eligibility checker, we'll need to perform a home survey to make sure we can install cavity wall or loft insulation. Only one upgrade can be installed, so if you're eligible for both, we’ll help you work out which improvement is most beneficial for you and your home.

Which route will you qualify for?

If you qualify through either route 1 or 2, you'll get free* cavity wall insulation.

Alternatively, you could also get free first-time loft insulation, but if you already have an existing layer of loft insulation, you'll need to pay a contribution. You may also need to pay for scaffolding3 if required. A home survey and terms and conditions apply to all installations.

What is the Great British Insulation Scheme (GBIS)?

The government insulation scheme started out as ECO+, with the aim of helping eligible UK homeowners install home insulation to make their homes more energy efficient with energy-saving improvements. At the heart of the scheme are affordability and comfort, so if you make your home more energy efficient, it will keep a consistent temperature, making it more cost-effective and cosy. The scheme was launched in the summer of 2023 and will run until March 2026.

Here are the energy-efficient upgrades that are available through E.ON:

We'll recommend the most suitable upgrade for you.

How does cavity wall insulation work and what are the cost savings with GBIS?

Depending on when your home was built, you may have cavity or solid walls. The cavity is where there is a space between the inner and outer walls of your home. If it's left without insulation, there is nothing to stop the heat you generate from being lost. We'll fill your cavities with insulation to keep your home warmer in the winter and cooler in the summer. Our insulation comes with an insurance-backed guarantee that lasts for 25 years, giving you peace of mind that the insulation will keep on working and saving you money on energy bills for years to come. And the good news is, if you're eligible, we will install it for free.* Check if you qualify with our online eligibility checker.

Does loft insulation work and will GBIS help make energy savings?

Yes, it does, and here's why: any house with a loft needs insulation to keep the heat in the living area from escaping through layers of insulation that may no longer work as well as it once did. Most homes already have some insulation in the loft or roof space, but over time it loses its effectiveness and may not be at the recommended level of 270mm, costing you more in energy bills. If you're eligible, we can install a new blanket of insulation to reach the recommended level to help your home stay nice and cosy this winter and help towards reducing your energy costs.

If your home doesn't have any loft insulation, we can install it for free.* But if you already have a layer of insulation but it's not to the recommended level of 270mm, you will need to pay a contribution. 

This will be subject to eligibility criteria, a home survey, and terms and conditions. Check if you qualify through our online eligibility checker.

Taking steps to slow down climate change

As the UK strives to meet ambitious climate targets, reducing energy consumption in residential homes is vital. By improving home insulation, the scheme contributes to lower carbon emissions and a more sustainable future, all while saving the homeowner or private renter on their energy costs. Why not kickstart your steps towards climate change and energy savings.

You could reduce your energy costs further with an air source heat pump

An air source heat pump generates its heat from the air, not only will it help cut your energy costs6, it'll also reduce the amount of carbon dioxide6 you put into the air, creating a greener future. With the boiler upgrade scheme, you can save £7,5007 on the cost of installation.

If you want your air source heat pump to work as efficiently as possible, you'll need to make sure your house is well insulated. If your home's loft and walls don't have enough insulation, heat will escape, making the heat pump work harder and possibly removing any savings you made on energy.

Insulating your home will help you save money on energy costs, whether you're looking to buy a heat pump or just make your home more energy efficient.

Improve the energy efficiency of your home with GBIS and E.ON

The Great British Insulation Scheme is your pathway to a more sustainable, energy-efficient home. By enhancing insulation and exploring complementary solutions like air source heat pumps, you'll not only reduce your energy bills but also make a significant contribution to a greener future. Start your journey towards a more comfortable, cost-effective, and eco-friendly home with warm insulation.

GBIS FAQs

What's the difference between ECO4 and GBIS?

In early 2022, the ECO4 scheme targeted those living in homes with low EPC ratings and qualifying benefits, but it excluded those from the least energy-efficient households that don't receive additional government support. The Great British Insulation Scheme will help hundreds of thousands of homeowners insulate their homes.

How do I check my council tax band?

Please visit check your council tax band.

What is an EPC rating and how can I check it?

An Energy Performance Certificate (EPC) lets all UK homeowners or tenants know how much energy their home is using or losing. The EPC will provide you with a rating from A to G, with A being the best and G being the worst. Please visit check my EPC rating, and if you don't have one you can get a new EPC certificate. Alternatively, once you apply, our online eligibility tool will let you know your EPC rating, if you have one. Find out how EPC ratings can help you plan your sustainable home.

Do I need to be an E.ON Next customer, and will I have to pay extra for anything?

Not in most cases, but if you don't fit the eligibility criteria, you may have to part-pay for the cavity wall installation costs of £500 and pay for scaffolding and ventilation if we can't reach certain points of your home in a safe way. Again, with loft insulation, depending on your circumstances, you may need to pay a contribution of £1,600. We'll let you know when we book your no-obligation home survey. After that, it's completely up to you if you want to go ahead.

Will I qualify if I live in social housing?

Not for this offer, but you could be eligible for funding through the ECO4 scheme or the Social Housing Decarbonisation Fund.

Can I choose what type of insulation I want?

Once we've done your home survey, you might be eligible for both cavity wall and loft insulation. We're only able to install one energy-efficient upgrade for each qualifying property. Our Qualitymark-accredited installers will help you work out the most energy-efficient upgrade for your home to help you save money on your energy bills.
