Trust ZOA Energy Solutions to guide you through the insulation grant process

If you’re considering installing external wall or solid wall insulation, then it’s worth looking into the grants that are out there. Why? Because it could mean free external wall insulation for you. External wall and solid wall insulation grants are being utilised by thousands of households across the UK to help cover the cost of installing insulation in their home. And all you need to do to get started is fill out our quick 60 second form with the following information:

  • Your address 
  • Your name 
  • Your email 
  • Your phone number 


As soon as you have, we’ll be able to contact you with some questions regarding your eligibility for certain grants to see if you qualify. If you do, we’ll help you through the process and install the insulation, too, so we really are your one stop shop for all things eco home improvements.

Is External Insulation Worth It?

Absolutely! There’s a reason adding external insulation to your home is becoming more popular than ever, and it’s because of the range of benefits it can bring your way. An external insulation grant will mean:

  1. Better energy efficiency at home
  2. Money saved on energy bills due to your home’s improved thermal performance
  3. Reduced carbon emissions from your home helping to save the environment


There’s plenty of additional benefits, too, but the main benefit when considering if external insulation is worth it is the second point. The money you’ll save each month will eventually cover the cost of installation – and if you qualify for external wall insulation grants, then you could receive free external wall insulation anyway – meaning your new insulation will put more money back into your pocket through energy bill savings each month.

External Wall Insulation Grants: All You Need To Know

External wall insulation grants change regularly, but if you stick with ZOA Energy Solutions, we’ll keep you up to date. If you’re unsure if the information below is correct, contact us today and one of our customer service team will talk you through the insulation grants you may qualify for and any changes or updates to the schemes and grants below.

External Insulation Grant/Funding List

  • Great British Insulation Scheme 
  • ECO4
  • LA Flex
  • 0% VAT

What Is The Great British Insulation Scheme 2023?

The Great British Insulation Scheme, formerly known as ECO+, begins in summer 2023 and will last until March 2026. It’s set to offer a total of £1 billion in funding to the least energy efficient homes in Great Britain – but there are certain criteria you’ll need to meet in order to qualify for free external wall insulation.

How Do You Qualify For The Great British Insulation Scheme?

The aim of the scheme is to insulate the least energy efficient homes in Great Britain to help vulnerable households control spiralling energy bills, reduce the carbon emissions their homes produce, and improve their Energy Performance Certificate (EPC) ratings. 

In order to qualify for the Great British Insulation Scheme, you’ll need to be:

  • Living in a home with an Energy Performance Certificate (EPC) rating of D-G, AND
  • Living in a council tax band A-D in England, A-E in Scotland and Wales




  • Be receiving means tested benefits AND
  • Have an EPC rating of D or below


If you meet this criteria, you may qualify for an external insulation grant under the scheme.

How Much Will I Save With External Wall Insulation?

The UK government estimates that households in the least energy efficient homes could save as much as £300 to £400 each year on energy bill savings alone. And the amount of money you’ll receive towards the cost of external wall insulation could mean the insulation is free too. 

The amount of money you’ll receive for the Great British Insulation Scheme will be decided on a case by case basis, so some will receive a grant that covers the full cost of external wall insulation, and others will receive a grant that covers most of the cost of external wall insulation.

What Is The ECO4 Scheme For External Wall Insulation?

You’ll no doubt have already heard of ECO4 in some capacity – but you might not realise that the scheme offers external wall insulation grants as well. First introduced in April 2022 and running until the end of March 2026, the scheme offers £4 billion worth of funding to support eco home improvements across thousands of poorly performing UK homes in terms of their energy efficiency. 

As with any grant, though, there are eligibility criteria that must be met in order to qualify for the external wall or solid wall insulation grants that are on offer here.

Who Is Eligible For ECO4 Insulation Grants?

This scheme, much like the Great British Insulation Scheme, aims to support low income households living in energy inefficient homes, but there are different criteria for each scheme. 

To qualify for ECO4 support you must meet these requirements:

  • You’re in receipt of government benefits OR someone in your household/a tenant is (a list of applicable benefits can be found below)
  • You have an inefficient heating system with a D-G energy efficiency rating
  • You receive child benefit AND your household income falls below a specific threshold (more on this below)

Applicable Government Benefits

  • Income-Based Jobseekers Allowance
  • Income-Related Employment & Support Allowance
  • Income Support
  • Pension Credit Guarantee 
  • Working Tax Credit
  • Child Tax Credits 
  • Universal Credit
  • Housing Benefit
  • Pension Credit Savings

Child Benefit Household Income Thresholds

So long as you’re in receipt of child benefit and have a total annual household income less than the numbers shown below you should be eligible for external wall insulation funding under ECO4: 


1 Child

2 Children

3 Children

4+ Children

Single-Parent Households





Two-Parent Households





LA Flex As An Alternative For External/Solid Wall Insulation Grants

It may come as a surprise to some of you, but even if you don’t qualify for an insulation grant under the Great British Insulation Scheme or ECO4 Scheme, it isn’t the end of your insulation grant options just yet. 

LA Flex (or the Local Authority Flexible Eligibility Scheme, to give it its full title) is a scheme that falls under the umbrella of ECO4, but it works a little differently in terms of the eligibility criteria. 

Under LA Flex, local authorities and councils are given the power to extend the eligibility criteria to better support homes that need it in their local area. Of course, they still target the most vulnerable, low income households with the poorest performing homes in terms of thermal efficiency, but with LA Flex, they get to help more of those homes that may have otherwise been left on the sidelines.

Who Is Eligible For LA Flex Insulation Grant Support?

Unlike ECO4, LA Flex doesn’t require you or someone in your household to be in receipt of benefits, but it does require you to:

  • Have an annual household income of less than £31,000, OR
  • Have health problems that may be worsened by living in an energy inefficient home such as cardiovascular problems, mobility issues, respiratory issues, or immune-suppressed conditions, OR
  • Meet two of the following criteria whilst living in a home with an energy rating of E, F, or G:
    • House in LSOA 1-3 Area (recognised as an area of deprivation in the UK)
    • Householder receives Council Tax rebates due to low income 
    • Householder is considered vulnerable to living in a cold home according to nationally recognised NICE guidance
    • You have been referred to LA Flex by the Local Authority Delivery (LAD) Scheme due to being vulnerable and in a low income household
    • Members of the household are in receipt of free school meals
    • Citizens Advice, your energy supplier, or your mortgage lender has advised you to seek help from government schemes due to sustained debt on mortgage payments or utility bills

Remember: LA Flex gives local authorities and councils the power to create their own eligibility criteria in order to improve targeted support. So even if you don’t meet the criteria above, your council or local authority may have extra criteria that could mean you could qualify.

How Long Will 0% VAT On Insulation Last?

The UK government has put 0% VAT on all Energy Saving Materials in the UK – and external or solid wall insulation comes under that. 0% VAT for insulation was first introduced in April 2022, and is set to run until the end of March 2027.

With 0% VAT, you’ll automatically save big on insulation, and there’s no eligibility criteria or restrictions here – if you buy a qualifying product like insulation, then the 0% VAT is automatically applied.

External Wall Insulation Grants FAQs:

It’s difficult to say exactly how much external wall insulation will cost because each house is different, and the final cost will be affected by things like:

  • House type: detached houses will cost significantly more to externally insulate than a mid terrace, for example
  • House size: the larger your property, the more it will cost to insulate
  • Finish of the insulation boards: insulation boards are most commonly used to insulate homes externally in the UK, but they come with a range of finishes that could cost more depending on what you choose 


On average, though, you can expect to pay between £6,000 and £20,000 for a full external wall insulation installation. 

Typically, no. Unless your house is in a conservation area, is a listed building, or in an area of outstanding natural beauty. If you’re unsure, talk to one of our experts who will be able to offer guidance about what to do next.

External or solid wall insulation will last for around 30 years without issue.

Each grant has a different application process, so each one will need handling a little differently. Thankfully, our expert customer service team is on hand to give you the latest advice. Fill out our quick form today, find out if you qualify for any insulation grants, and if you do, we’ll tell you what you can do next to access them. 

No. Grants are not designed to be paid back, meaning any money that’s given towards the cost of your insulation doesn’t need to be repaid at any point, potentially meaning you won’t have any upfront costs for your external wall insulation at all.
