Grants for room in roof insulation are now available in the UK. Insulation is crucial to the energy efficiency and comfort of our homes.

Those residing in homes with sloped or “room in roof” designs have an even greater need for appropriate insulation.

However, for many homeowners, the cost of installing or upgrading insulation can be an obstacle. Fortunately, several grants are available to help reduce these expenses, promote energy efficiency, and reduce carbon footprints.

This article will explore the various available grants for room-in-roof insulation, their eligibility requirements, and how to access them.

Why should you insulate your room in roof?

Insulating your room in the roof, which is commonly found in loft conversions or attic spaces, is a wise choice for a number of reasons. First, it improves your homes energy efficiency by preventing heat loss through the roof, allowing you to save money on heating costs.

It maintains consistent temperatures throughout the year, keeping your room toasty in the winter and cool in the summer. Additionally, proper insulation can enhance acoustics by reducing noise transmission from the exterior.

Whether you’re seeking to save money, increase comfort, or create a quieter retreat in your home, insulating your attic is a worthwhile investment that can improve your overall quality of life.

Available grants for room in roof insulation

ECO4 ends on 31 December 2026We can no longer help with ECO4 applications. The Great British Insulation Scheme closed on 31 March 2026. You can apply for a free home battery or see other funding options.

ECO4

Introduced in the UK in 2013, the Energy Company Obligation (ECO4) is a scheme through which main energy suppliers fund energy efficiency improvements for eligible households. The current version of the scheme runs from 2022 to 2026. 

The Eco4 scheme plays a critical role in decreasing carbon emissions, lowering energy bills, and contributing to a greener and more environmentally responsible future for the UK by providing grants and incentives for measures such as insulation and renewable energy installations.

Eligibility requirements:

  • Income-based job seekers’ allowance
  • Income-related employment and support allowance
  • Income support
  • Pension credit guarantee credit
  • Working tax credit
  • Child tax credit
  • Universal credit
  • Housing benefit
  • Pension credit savings credit
  • Child benefit (with dependencies)

Either you reside in private housing (owned or rented) and receive a qualifying benefit, or you reside in social housing with an energy efficiency rating of E, F, or G to be eligible for ECO4 funding.

Check your EPC Rating

Energy Performance Certificates

An Energy Performance Certificate (EPC) tells you how energy-efficient a property is. It would be best if you had an EPC  in England and Wales when you’re:

  • selling a property
  • renting out a property
  • building a new property

You must order an EPC for potential buyers and tenants before you market your property to sell or rent.

In Scotland, it is not compulsory to have an EPC rating though there is talk of legislation changing this in the future.

An EPC contains:

  • information about a property’s energy use and typical energy costs
  • steps to improve a property’s energy efficiency and save money

An EPC gives a property an energy efficiency rating from A (best) to G (worst) and is valid for 10 years.

The green homes grant

The green homes grant is no longer valid. 

The green homes grant, another initiative introduced by the British government, provides homeowners with vouchers to help defray the cost of energy-efficient home improvements, such as insulation. Its popularity may have been extended or supplanted by a similar scheme, despite the programmes March 2021 expiration date.

Under the green homes grant, homeowners could apply for vouchers covering up to two-thirds of the cost of eligible home enhancements, up to a maximum of £5,000. For low-income households, vouchers could cover the total expense of up to £10,000 in home improvements.

Local authority flexibility scheme (LA Flex)

Energy suppliers fund energy efficient upgrades through the Energy Company Obligation (ECO4), which runs until 31 December 2026. The LA Flex scheme is one of the routes into ECO4 for homeowners, tenants and landlords, so it ends at the same time.

The following may be available to you through the LA Flex Scheme:

To be eligible for the LA Flex fund, you must satisfy one or more of the following requirements:

  • Low-income: If the household income is less than £31,000 before tax you will qualify through route 1 of the LA Flex scheme.
  • Certain conditions that are impacted by the cold: Those with respiratory disease, cardiovascular disease, neurobiological disease, cancer, limited mobility, or autoimmune and immunological diseases will qualify via route 3 of the LA Flex scheme. 

Warm home discount scheme

Although the warm home discount scheme is not a grant for insulation, it can significantly relieve households with excessive energy bills. It provides a £140 rebate on your electricity bill between October and April, potentially freeing up funds for energy-efficient upgrades such as insulation.

The Great British Insulation Scheme

The Great British Insulation Scheme (GBIS) was a supplier obligation designed to improve the energy efficiency of British homes. It began in April 2023 and closed to new installations on 31 March 2026.

Use the grants available

No one should be required to sacrifice their  homes comfort and energy efficiency due to financial constraints. Numerous grants for room-in-roof insulation offer homeowners the chance to improve their homes and substantially reduce their energy costs.

Whether through government schemes such as ECO4, the green homes grant or local government initiatives, a variety of resources are available.

Final Thoughts

In an era where energy efficiency and sustainability are paramount, these grants provide financial assistance and contribute to a greener and more sustainable future. 

Insulating your room-in-roof can provide several advantages, including increased energy efficiency, a smaller carbon footprint, and substantial energy bill savings. To see what help is available now, read our guide to current home energy grants.
