The Great British Insulation Scheme

Eco + scheme for houses

If you’ve been waiting for the ECO+ grant for a while, then you might be confused as to what has happened to the ECO+ scheme. Due to launch earlier in 2023, ECO plus was actually pushed back until summer 2023 because the government decided to rebrand the scheme as the Great British Insulation Scheme (GBIS). Essentially, the ECO+ scheme is still going, it’s just now under a new name. 

 To help clear things up, we’ll discuss the Great British Insulation Scheme below, what its aims are, who is eligible for support under it, and whether there are any changes since it was rebranded. 

Why Did ECO+ Change Its Name?

The ECO+ scheme was set to launch in 2023, but as part of the UK government’s ‘energy revolution’ launched at the end of March 2023, the scheme was rebranded to better fit their ‘Powering Up Britain’ initiative designed to drive multi billion pound investment in the UK with a long-term energy security and independence plan. 

The aim is to cut British household energy bills by improving energy efficiency. One way of doing that is with insulation, hence the change in name from the ECO+ grant to the Great British Insulation Scheme. 

What Is The Great British Insulation Scheme?

The Great British Insulation Scheme replaced the ECO+ scheme in summer 2023, and whilst its aims are largely the same as ECO plus, it does seem to be being delivered on a much larger scale. 

The scheme aims to target the worst performing homes in terms of energy efficiency, and also aims to support the lowest income households in Britain. By improving the insulation in properties with an Energy Performance Certificate rating of D or below, the government is helping in a number of ways. 

First, the energy efficiency improvements will greatly reduce the amount the homeowner will pay in terms of energy bills each year. With better insulation, the home will stay warmer for longer, meaning the household will pay less to heat their home. 

The second, and most important benefit in the eyes of the UK government no doubt, is that better insulation in homes with poor energy efficiency means fewer carbon emissions. And fewer carbon emissions by British homes means the government will move closer to their legally binding target of Net Zero carbon emissions by 2050. 

What Is Covered Under The Great British Insulation Scheme?

It won’t come as a surprise to many of you that the Great British Insulation Scheme focuses on insulation. Admittedly, the new name makes that a lot clearer than the ECO plus scheme ever did. 

 But under that umbrella term, it’s probably worth looking into the different types of insulation the Great British Insulation Scheme covers:  


As you can see, there are several different types of insulation that could be funded by GBIS. The majority of installations will be loft insulation, since this is the least expensive insulation option (and the funding will therefore be able to help as many households as possible), but other insulation measures, are possible, especially if the property doesn’t have a loft space or it it’s roof space is already insulated.

Why Bother Applying For The Great British Insulation Scheme?

You might be wondering if applying for the scheme is even worthwhile – what benefits will you get by installing insulation through the GBIS anyway?  


Comfort Your home will stay warmer in winter and cooler in summer when you install insulation of any kind, making your home a more enjoyable place to be
Lower energy bills With your home staying warmer for longer thanks to your new insulation, you’ll spend far less on heating your home than you do now, saving you £100s per year
Energy efficiency  Insulation of any kind will make your home far more energy efficient, meaning your EPC rating will increase
Higher house value Taking active steps towards improving your energy efficiency is a great investment because it means any future buyers don’t need to think about it for a while – raising your home’s value
Greener home Better insulation = less carbon emissions = a greener home, meaning you’re doing your bit to reduce your carbon footprint


Who Is Eligible For Support Under GBIS?

As mentioned above, the scheme is targeting the lowest income households in Great Britain living in the least energy efficient homes. As such, the scheme targets two main groups: ‘the general group’ and ‘the low-income eligibility group’. 

Eligibility For The General Group 

To be eligible for the general group, you’ll need to be: 

  • Living in a home in lower council tax bands A-D in England, or A-E in Scotland and Wales
  • Living in a home with a low energy efficiency EPC rating of D or below


Eligibility For The Low-Income Group

To be eligible for the low-income eligibility group, you’ll need to be: 

  • Living in a home with an EPC rating of D or below 
  • Receiving means tested benefits from the government


I’m Eligible – What Support Am I Entitled To?

Being eligible for support under the Great British Insulation Scheme means you’re entitled to a single insulation measure to help improve the energy efficiency of your home. This single measure may be free, if it is determined that you’re entitled to the full cost being covered by the grant. In some cases, you may have to contribute towards the cost of the insulation energy efficiency measures, but this will be at a significantly reduced cost. 

How Do The ECO+ Scheme And The Great British Insulation Scheme Differ?

Generally, not much changed between the proposed ECO+ scheme 2023 and the Great British Insulation Scheme besides the name. Both were designed to sit alongside the ECO (Energy Company Obligation) scheme, now in its fourth iteration, but they are distinct schemes in their own right.  

ECO4 aims to support low income households in energy inefficient homes too, but has a more whole-house approach. The Great British Insulation Scheme, focuses only on a single measure of insulation to make households considered to be in fuel poverty become more energy efficient and protect them from energy prices.

How Do I Apply For GBIS Support?

Applying for support for the Great British Insulation Scheme can feel complicated, especially if you’re unsure if you qualify or not.

We’ll be able to tell you in 60 seconds if you qualify, and then if you do, we can even help you through the grant application process, making the entire process completely hassle free. 

Great British Insulation Scheme Summary

The ECO+ scheme became the Great British Insulation Scheme in March 2023, and although it has a new name, its aims are still largely the same. If you live in a home with a low EPC rating, receive means tested benefits (for the low income group) or live in council tax band A-D in England, A-E in Wales and Scotland (for the general group), then you might qualify for support.  

The best way to find out if you qualify for support is with ZOA Eco Grants. In just 60 seconds, and with just a few questions, we’ll be able to look at your circumstances and let you know what grant support you’re entitled to. And, even better, we’ll be able to support you with the installation, too. At ZOA Energy Solutions, we can carry out your insulation installation too as expert eco home improvement installers! 

Great British Insulation Scheme FAQs:

I qualified for the ECO+ grant – do I qualify for support under the Great British Insulation Scheme?

Yes, if you were set to qualify for support under ECO+, you should still qualify under the Great British Insulation Scheme. Check with us today to be sure. 

What is the new ECO scheme 2023? 

The new scheme is the Great British Insulation Scheme – ECO+ was replaced by this in March 2023. ECO4 is still ongoing, and started in July 2022. 

Will I get completely free insulation under the Great British Insulation Scheme?

In some cases you will receive a single measure of insulation under the scheme for free. Most typically this would be loft insulation, though other types of insulation, such as cavity wall insulation, may also be covered by a grant.

In some other cases you will receive a single measure of insulation, but may be require to make a contribution to the cost because your grant might not cover the full cost. 

 This is decided on a case by case basis during the application. Work with ZOA Eco Grants today and we’ll guide you through the process.
