What Is the Purpose of Window Grants From the UK Government?


Window grants in the UK primarily serve two main purposes:

  • Enhancing Energy Efficiency: Replacing old, draughty windows with new, energy-efficient ones can significantly reduce heat loss in homes. This, in turn, helps lower energy consumption and reduces the carbon footprint, contributing to the UK’s overall environmental goals.
  • Cost Savings: Energy-efficient windows are designed to better insulate your home, which means you’ll spend less on heating and cooling. Over time, this translates to significant savings on your energy bills.

Are There Any Double Glazing Grants Available in the UK in 2023?


As of 2023, there are some schemes ending and others emerging. The availability of double glazing grants can vary depending on your location and specific circumstances. In this section, we’ll explore some of the key grants and schemes available to UK residents.

ECO4 (Energy Company Obligation Scheme):

ECO4, launched in April 2022 and set to run until March 2026, is part of the UK government’s Energy Company Obligation scheme. It is administered by Ofgem and requires energy suppliers participating in the scheme to fund energy-efficient home upgrades. 

This includes measures like double glazing and boiler upgrades. To qualify for this grant, you must be part of the core group under the Warm Home Discount Scheme or receive at least one of the following benefits:

  • Universal Credit
  • Housing Benefit
  • Income-related Employment and Support Allowance (ESA)
  • Income-based Jobseeker’s Allowance (JSA)
  • Income Support
  • Child Benefit
  • Tax Credits (Child Tax Credits and Working Tax Credits)
  • Pension Guarantee Credit
  • Pension credit saving credit

It’s advisable to check with your energy supplier for their specific criteria, or you can verify your eligibility for an Energy Company Obligation grant.

This scheme is available to recipients of means-tested benefits like Income-based Jobseeker’s Allowance, Universal Credit, and Income Support. It provides a valuable opportunity for homeowners to enhance their homes’ energy efficiency.

Home Energy Scotland Grant

The Home Energy Scotland grant is initiated by the Scottish Government and targets low-income, energy-inefficient homes in Scotland. It offers grants of up to £7,500 to make energy efficiency improvements, including double glazing replacements.

While it covers double glazing replacements for homes with single glazed windows, those with existing double glazing units are typically not eligible.

Affordable Warmth Scheme in Northern Ireland

The Affordable Warmth Scheme, operational since 2014, aims to protect low-income homes in Northern Ireland from fuel poverty by providing financial assistance of up to £7,500 for energy efficiency improvements. This can include new double glazing installation.

Homeowners and tenants with a total gross income of less than £23,000 per year can apply for this scheme, with the granted amount subject to approval based on home inspections and individual needs.

Home Upgrade Scheme

Beginning in April 2023, the Home Upgrade Scheme allocates £1.4 billion in funding to local authorities and social housing providers in England. This funding is intended for energy efficiency measures in homes with an Energy Performance Certificate (EPC) rating of D and below.

These measures encompass loft insulation, draught-proofing, new doors, and double glazing. The scheme is expected to benefit over 115,000 homes in England, potentially saving tenants between £220 and £400 annually on their energy bills.

Eligibility Criteria For UK Government Double Glazing Window Grants


To benefit from window grants in the UK, you need to meet certain eligibility criteria, which may vary depending on the specific grant or scheme. In general, some things to look out for may be:

  • Location: You must be a UK resident to apply for most window grants.
  • Age of Property: Grants are typically available for properties that are older than a certain number of years. This is because older homes often have less energy-efficient windows, making them a priority for upgrades.
  • Income Level: Some grants are means-tested, meaning they are only available to households with specific income levels. This ensures that assistance is directed to those who need it most.
  • Type of Property: Some grants may be restricted to certain types of properties, such as private residences, rented accommodations, or social housing.
  • Previous Upgrades: In some cases, grants may be available to homeowners who have not previously received assistance for energy efficiency improvements.

Benefits of Double and Triple Glazed Windows


Investing in double or triple glazed windows, especially with the support of a Green Homes Grant, comes with a multitude of benefits that extend beyond energy savings. Here are some of the advantages of upgrading to these energy-efficient window options:

  • Lower Heating Bills: Improved insulation through double or triple glazing means less heat escapes through your windows. This reduces your reliance on heating systems and, consequently, lowers your heating bills.
  • All-Season Comfort: Double or triple glazing keeps your home more comfortable year-round. It retains heat during the winter and prevents excessive heat from entering in the summer.
  • Enhanced Home Security: These types of windows are more durable and resistant to breakage, making your home more secure. Their added strength acts as a deterrent to potential intruders.
  • Reduced Condensation: Double and triple glazed windows create an airtight seal that prevents moisture buildup and the formation of mould.
  • Improved Acoustic Comfort: These windows reduce noise pollution, making your home quieter. This is particularly beneficial if you live in a busy area or near noisy roads.
  • Lower Carbon Emissions: Reduced heating usage leads to decreased carbon emissions, allowing you to contribute to environmental sustainability and the fight against climate change.
  • Property Value Boost: Installing double or triple glazing can enhance the attractiveness of your home to potential buyers. It’s considered a valuable energy-efficient feature that can increase the overall value of your property.

Comparing Window Installers for Cost Savings


While window grants are a valuable means of reducing the upfront costs of new windows, there are additional steps you can take to save money on your window replacement project. One effective approach is to compare multiple window installers to ensure you’re not overpaying and that you’re getting the best value for your investment.

Comparing window installers can be a time-consuming and challenging task. To simplify this process and make it more efficient, you can use services like Warmable. This platform connects you with qualified window installers in your area from their trusted network. Here’s how it works:
