Double Glazing Grants – What Help Is There?

Written By:

Updated on

According to the Energy Savings Trust of the UK, installing a set of A-rated windows for a semi-detached house will typically cost around £7,500.

Despite this relatively high expense, the installation of A-rated double glazing to windows in an entirely single-glazed semi-detached, gas-heated property could lead to yearly savings of £195 a year.

In terms of carbon emissions, this could lead to 330kg less carbon dioxide emissions. For people who live in a very old house with windows that are older than 15 years, the energy and carbon savings may even be greater. 

However, with an average installation price starting at £300 per window (minimum), installing them can be a significant investment, and especially for low income households. 

If you’re considering installing double glazed windows, it is certainly important to search for double glazing grants that may help you save you money for qualifying homeowners.

  • There are several double glazing grants you can consider, especially if you live in Scotland.
  • The Green Deal, which offered a double glazing grant, closed in 2015 and you can no longer get assistance.
  • If you are over 60, you may qualify for multiple double glazing grants.

 In this guide you will find:

Are there any double glazing grants?

It is important to state up front that in 2023, there currently is not a specialized, dedicated government grant for double glazing. However, the ECO4 scheme might help some homeowners cover the cost of double glazing if they meet certain benefits criteria and income thresholds. For those households who do qualify, you may be eligible for up to £14,000 towards double glazing and other energy-saving home improvements.

Other people who may be eligible for receiving double glazing grants include people who are currently receiving government benefits, those over the age of 60, or people on disability.  The best way to lower your costs for installing double glazing is to ensure you get the best deal by comparing quotes, or try and finance the cost.

ECO4 Scheme

The ECO4 Scheme is the fourth (and supposedly final) stage of the government’s Energy Company Obligation (ECO) scheme. This current scheme has been active since April 2022 and ends March 2026.

The ECO4 Scheme aims to support low-income households who are unable to upgrade their homes energy efficiency and heating systems. The program partners with major energy suppliers in the UK to provide free home upgrades – including installing double glazing – to vulnerable households that meet the strict eligibility requirements. 

In fact, energy companies and suppliers in the UK with more than 150,000 domestic customers are required by law to support eligible applicants. In the best case scenario, the ECO4 Scheme could potentially cover 100% of the cost of double glazing, which is more than the average £11,050 it costs to install double glazing in a typical three-bedroom house in the UK. 

To be eligible for the ECO4 Scheme, you need to be actively receiving government benefits, such as: 

  • Income-based Jobseekers Allowance (JSA)
  • Income-related Employment & Support Allowance (ESA)
  • Income Support (IS)
  • Pension Credit Guarantee
  • Credit Working Tax Credit (WTC)
  • Child Tax Credits (CTC)
  • Universal Credit (UC)
  • Housing Benefit
  • Pension Credit Savings Credit

You can also fill out the ECO4 eligibility questionnaire to check if you meet the requirements.

In order to apply for this scheme, you will need to get in touch with one of the energy suppliers that are offering it. The energy supplier will do a telephone assessment with you wherein you will answer a few questions about your income, whether you receive benefits, and your property’s energy efficiency rating.

LA Flex

The LA Flex Scheme, also referred to as the Local Authority Flexibility, is a program that gives local authorities leeway to expand ECO4 eligibility to certain applicants who do not meet all the criteria outlined above.

With this program, ECO4 eligibility can be extended to households that are either living in fuel poverty, or those who are classified as vulnerable or low income. Your home also needs to have an EPC rating of D-G.

In order to apply for the LA Flex Program, you need to contact your local authority. In the optimum scenario, eligible homeowners may be able to receive up to £10,000 in funding for energy efficient measures such as double glazing.

The Green Deal – The Green Deal was the primary double glazing grant in the UK, but it has been discontinued since 2015.  The Green Deal offered up to £7,600 in loans to homeowners to install home improvements including double glazing, and was paid back through energy bills by taking the estimated cost savings per month from the energy bill. This allowed homeowners to get ‘free’ upgrades to their homes because their energy bill would remain the same and they wouldn’t have to invest money in glazing. However, the Green Deal was ended in 2015 and it will not be coming back.

Home Upgrade Grant

The Home Upgrade Grant offers home improvement and energy efficient grants from £3,000 to £24,000. These grants are directed towards home improvements that increase a property’s energy efficiency, including double glazing. In the best case scenario, you may be able to receive up to 40% of the total amount granted can be spent on double glazing.

The Home Upgrade Grant is currently only available in 45 local authorities in England. This program is scheduled to operate from April 2023 to March 2025. It is only available to low-income homes that are off the gas grid, including homeowners, renters, and those living in social housing.

In the best case scenario, the Home Upgrade Grant could cover around 87% of the cost of double glazing. Since double glazing costs the average three-bedroom house just over £11,000, and 40% of the up to £24,000 grant can be spent on windows, you could theoretically save up to £9,600 on double glazing purchase and installation costs. 

To be eligible for the Home Upgrade Scheme, your will need to abide by the following eligibility requirements: 

  • A household income of less than £31,000 a year
  • Your household is off the gas grid
  • Your home has an EPC rating of D, E, F, or G
  • You live in one of the 45 local authorities that applied for the grant

Housing Aid for Older People Scheme – The Housing Aid for Older People Scheme is designed to assist persons over the age of 66 who are living in poor conditions. If your windows are broken, damaged, or negatively affect your ability to live in the home, the HAOPS may cover up to 95% of total costs or a maximum of £8,000. Applicants are subject to a means test, and grants are awarded based on means and need. To apply, contact your local authority and download an application from their site.

Double Glazing Grants in Scotland and Ireland 

If you live in Scotland or Ireland, there may be many more opportunities for double glazing grants.

Home Renovation Incentive

For people who live in Ireland, you can claim the Home Renovation Incentive for qualifying work up to a value of £30,000. This program focuses on free energy upgrades and is called the Warmer Homes Scheme. It is important to note that new central heating systems and replacement windows are also occasionally covered by this scheme. Double glazed windows will only be replaced if your walls are being insulated at the same time and the existing windows are single-glazed windows. The SEAI decides this on a case by case basis. 

Home Energy Efficiency Programmes for Scotland (HEEPS)

This program is available to Scottish private sector landlords and homeowners looking to handle home improvements. These schemes are designed to increase the take-up of home energy efficiency measures and also to help reduce fuel poverty, while also helping the country reach its carbon emission reduction targets.

Though the energy efficiency programmes through HEEPS are mainly focused on improving solid wall insulation in areas with high levels of fuel poverty, you may be able to apply for interest free loans for other energy efficiency home improvements including double glazing. 

Can I get free double glazing?

If you are over the age of 60, living on benefits, or otherwise in dire need of assistance, you may be able to get free double glazing in the UK. Otherwise, you most likely do not qualify or will have to settle for low interest loans for double glazing projects aimed at improving your home´s energy efficiency. Green Deal was the only double glazing grant aimed at general homeowners, and there is not a replacement for the scheme.

However, you can still greatly reduce the cost of double glazing, and if you live in the right area and meet certain eligibility requirements. 

Can I get assistance with double glazing through a housing association?

Many housing associations and councils set aside funds to repair and improve homes. However, they may not cover the costs of double glazing unless the glazing is necessary to providing quality of life or will greatly reduce energy bills enough to cover the costs of the installation. Contact your housing association or local council to see if they will offer you assistance.

Who’s responsible for paying for double glazing if I rent?

Private sector landlords are only responsible for home upgrades when they include repairs. This means that if your home includes old single glazing, they are not responsible for the cost of upgrading. If you choose to upgrade yourself, you will be responsible for paying for the installation, and you will need permission from the landlord to do the work.

Double glazing finance schemes

While there are no real double glazing grants for homeowners without extraordinary need, you can alleviate the cost of double glazing with a finance scheme. In most cases, finance schemes will charge a low rate per month, allowing you to make small payments over the course of the lifetime of the windows. For example, top double glazing installers like Anglian and Everest all offer finance schemes with monthly payments under £100. Ask your installer if they offer financing before signing the contract if this is an option for you.

Saving money on double glazing

If you don’t qualify for a double glazing grant, you may still be able to cut costs by researching your options, making the best decisions for your needs, and getting a good deal.

Go local – Local installers often pay less VAT, which can translate to direct savings for you.

Know what you want – If you know what windows you want and what they cost, it’s difficult to accept a higher quote. Most double glazing sales representatives work on commission, which is typically about 10-15% of the total project, so it’s in their best interest to charge you as much as-is possible. Check the frames, type of windows, glazing, and energy rating you want and then make sure you know what it should cost. If you’re quoted more, ask why.

Compare your options – Just comparing your options can save you significantly because you’ll be able to choose the best quote from all your options. Make sure that you understand what you’re getting for the quote, what’s included, and what isn’t.

If you’re ready to install double glazing, the best way to save money is to compare your options. You can use our free tool to get competitive quotes from top installers in your area. We will contact suppliers in your area to request competitive quotes, which can be up to 47% lower than getting them yourself. Then, we’ll forward you the best three quotes from top rated suppliers, so you can choose, or not. There’s no obligation.
