Designed to support eligible homeowners in making energy efficient improvements to their homes.

What is the Green Homes Wales scheme?  

Green Homes Wales is a Welsh Government initiative, managed by the Development Bank of Wales, designed to support eligible homeowners in making energy efficient improvements to their homes. The Scheme offers both interest free financing and fully funded expert support, helping you save money on energy bills and reduce carbon emissions. 

We offer comprehensive support to help you make your home more energy-efficient, including: 

  • Expert guidance: 
    • Fully funded access to a Retrofit Coordinator to create a detailed home assessment providing energy-efficiency and decarbonisation recommendations tailored to your individual circumstances.

  • Flexible financing: 
    • Interest free loans ranging from £1,000 to £25,000 with repayment terms up to 10 years. For larger projects, terms may be extended. 
    • Enjoy a 6-month upfront repayment holiday while your new energy efficiency measures begin delivering results.

  • Grant funding: 
    • Access to grant funding alongside loans for specific energy efficiency measures, reducing your out-of-pocket expenses. 

Please note: all applications will be subject to affordability and credit score checks.

Are you eligible?

To qualify for the scheme, the homeowner/s:  

  • will not be means tested 

  • will be required to pass credit checks and affordability assessments 

 

To qualify for the scheme, your home must: 

  • be located in Wales; 

  • be owned by you; 

  • be your primary residence; and  

  • not be a new build property (i.e. homes that have been built in the last 6 months and that have not previously been occupied) 

     

Listed buildings - the scheme does not currently support homes that are listed or are in a conservation area that require additional permissions for works to be carried out.  

Private landlords - Landlords cannot currently apply to this Scheme but should visit Climate Action Wales for further advice.  

 

A scheme you can trust

For quality assurance, Green Homes Wales embeds the requirement for PAS 2035 compliance across its structure and conditions of third parties that are engaged with it, including Retrofit Coordinators and installers. 

PAS 2035 is the overarching UK retrofit standards framework. It details how to carry out quality energy retrofits of existing domestic buildings, alongside best practice guidance for implementing energy efficiency measures. As a government backed standard, PAS 2035 provides a thorough approach to ensuring quality and assurance to all retrofit work undertaken. Further information can be found here.

Green Homes Wales FAQs

Before applying to the Green Homes Wales scheme, it's essential to seek general advice on the available options to you. This step is crucial for identifying any existing support you may qualify for from publicly funded schemes. 

Schemes such as Welsh Government’s NEST can help you understand your options and identify any existing public grant funding you may qualify for.  

You can contact the NEST team and see what you are eligible for by calling the free number 0808 808 2244 (Monday to Friday from 9am to 6pm, excluding bank holidays).

There are also other specialists you might want to try for information and advice:

You can also contact your local authority.

Alternatively if you have any specific questions on getting advice, please email the Green Homes Wales team.

The house must be located in Wales and must be your primary residence. 

Yes. Green Homes Wales provides funding only for owner occupiers to undertake energy efficiency measures on their primary residence. Note: landlords cannot currently apply to this scheme. 

A home retrofit is the process of making improvements and upgrades to your home so it becomes more energy efficient with lower emissions.  

A list of pre-verified retrofit coordinators will be available on the Green Homes Wales website once the scheme is launched in the Autumn. You will be able to choose a retrofit coordinator from this list to work with to complete a home energy assessment.  

No. Green Homes Wales offers a finance package which provides grant funding in certain circumstances. The grant cannot be accessed in isolation. 

Grants will be available to support certain measures where there is higher carbon impact or as part of a package of support measures. The full list of grant allocations will be available ahead of the scheme launch in the autumn.  

Once you’ve decided which measures you want to take forward you will need to speak to an accredited installer and get a quote for the work. For any low carbon technology installation i.e. solar panels or a heat pump you will need to use a Microgeneration Certification Scheme (MCS) certified installer. For all other work you will need to engage with a TrustMark registered installer. 

Applications for Green Homes Wales will be open in the autumn. The scheme will be available on a first come first serve basis subject to funding availability.

Yes. If you have fully repaid your first loan you can apply for further funding to undertake new energy efficiency measures.  

At this time, Green Homes Wales is not able to support these types of properties. We are however working with Cadw to help build the requirements and eligibility in this area (including Retrofit Coordinator expertise requirements) and hope to be able to support these types of homes from April, subject to extended funding being agreed for the Scheme. If you would like to register interest in hearing about further support in this area please email info@greenhomes.wales.

The project cost top up funding that is available alongside a grant from the Boiler Upgrade Scheme can support costs of the heat pump technology, supply and fitting/labour, as well as associated pipework and radiator costs.  

We have a duty to customers to ensure they are suitably able to manage repayments of any lending undertaken through the scheme. To support you we will assess the income and expenditure details you provide as part of the application to ensure that you have sufficient disposable income to make the repayments. Following Application A, we will advise you of the funding that might be available to you, subject to more detailed checks being undertaken as part of Application B, should you decide to proceed.   

No. Loans made from us will be unsecured but homeowners will be personally liable to make the agreed repayments.

The funding can be used to cover the costs of the supply and installation of the Eligible Measures. It will not cover any remediation work required or any project management or design costs- except where agreed specifically by the scheme. All costs must be incurred directly as a result of the project, limited to those strictly necessary for the project and limited to the time period of the project.  

Where insulation is being installed, or where additionally recommended by the Retrofit Coordinator, ventilation systems will be eligible for loan funding support.   

Please register your interest through the expression of interest form available on this page as the first step. This list will be managed by the team and applications sent out directly in line with ongoing funding availability. Due to initial high demand levels, it may be the case that you are placed on a waiting list for an application while other applications are reviewed. We will email out to let you know if this is the case. 

The scheme has a limited pot of funding. As a result, it will operate on a first come first serve basis. Submission of an application will not guarantee funding. Confirmation will be given in the form of a funding offer letter once the application is fully processed and the required documents and supporting information is submitted alongside it. 

There is no obligation to progress to take on project funding through the scheme following the home assessment and subsequent reports. However, the aim of the scheme is to support those looking to decarbonise and upgrade the energy efficiency of their homes to ultimately impact on the carbon emissions of the housing sector in Wales. If you do not think you are in a position to carry out the works then we would encourage you to apply at a more suitable time.
