In the UK, insulation grants for landlords are not directly available. However, tenants may qualify under schemes like the Energy Company Obligation (ECO). By collaborating with tenants and granting installation permission, landlords can access up to £40,000 in funding, improving property energy efficiency and value. 

Landlords cannot apply directly for home insulation grants because they are not the ones paying the energy bills or directly impacted by poor insulation within the property. Instead, eligibility is typically based on the tenant's circumstances, such as their income level or whether they receive certain benefits. 

Landlords can apply for grants, including wall insulation grants and loft grants, on behalf of their tenants if they obtain written consent before work begins. This applies for single or multiple properties; however, as a landlord, if you apply for grants with various properties, you will have to apply several times as there is no option for a multi-property grant application form. Collaborating with eligible tenants allows landlords to enhance their properties' energy efficiency, resulting in lower energy bills for tenants and increased property value for landlords.

Landlords in the UK aren’t required to provide insulation for a house unless the property is unfit to live in (e.g., severe cold or damp) or has an EPC rating of F or G. You can request insulation by checking the EPC rating, exploring ECO schemes, offering to share costs, and seeking advice from Citizens Advice for guidance on your rights.

In the UK, landlords are required to invest up to £3,500 in home improvements to ensure their rental properties are safe and habitable. These obligations are outlined under the UK’s Minimum Energy Efficiency Standards (MEES). Looking ahead, there are plans to tighten these standards, requiring landlords to achieve even higher energy efficiency ratings.

In the UK, two key insulation grants for landlords in 2025 are the Great British Insulation Scheme and the Energy Company Obligation (ECO4). With 4 in 10 adults struggling to pay energy bills according to the Office for National Statistics, these schemes aim to help low-income or fuel-poor households by providing support to upgrade insulation in private and rented properties.https://www.greenmatch.co.uk/insulation/grants/loft

Access to grants helps reduce insulation prices, leading to reduced energy consumption, lower bills, and decreased carbon emissions. For instance, free loft insulation provided through these grants can save tenants up to £380 annually on their energy bills.

These schemes are available until March 2026, but tenants must apply directly to qualify. Landlords are required to give written consent for any insulation work to proceed on their property. Applying early is highly advised to increase the likelihood of securing support through a grant program. Below we go into details on the two landlord insulation grants available. https://www.greenmatch.co.uk/insulation/grants/great-british-insulation-scheme

The Great British Insulation Scheme aims to make homes across the UK more energy-efficient by providing financial support for insulation upgrades. Targeted at households with low incomes or high energy bills, the scheme focuses on reducing energy consumption, lowering bills, and cutting carbon emissions.

Under this initiative, eligible properties can receive support for measures like loft, wall, and floor insulation, making homes warmer and more affordable to heat. Landlords can also benefit by collaborating with tenants to apply for these improvements, provided they give written consent for work to be carried out.

The scheme is part of the UK government's effort to meet climate targets while addressing fuel poverty. By improving the energy efficiency of private and rented properties, the program helps landlords and tenants. Applications are open until 2026, but applying early increases the chances of securing funding. For further details, tenants must check eligibility criteria and explore available grants.

The Energy Company Obligation (ECO4) is a UK government initiative designed to improve home energy efficiency. It focuses on low-income or at-risk households that are at risk of fuel poverty. Running until March 2026, ECO4 requires large energy companies to fund energy-saving upgrades, including insulation, heating system improvements, and other efficiency measures.

ECO4 prioritises homes with poor energy performance, particularly those with Energy Performance Certificate (EPC) ratings of D, E, F, or G. Eligible properties may receive support for loft, wall, or floor insulation and other energy-efficient improvements, helping to reduce energy bills and carbon emissions.

Tenants can apply for these measures, but landlord consent is required for work on rented properties. By participating, landlords can enhance their properties' value and energy performance. At the same time, tenants benefit from a warmer, more affordable home. Early application is recommended to maximise access to funding. For more details, check eligibility requirements and contact your energy supplier.

Landlord insulation grants in 2025 are designed to help private landlords improve the energy efficiency of their properties. Eligibility for these insulation grants for landlords varies slightly compared to homeowners, with specific criteria focused on the property and tenant circumstances.

Meeting these requirements enables landlords to access insulation grants, reducing costs, boosting property value, and enhancing energy efficiency. To determine your eligibility for landlord insulation grants, consulting with an insulation specialist is crucial.
