Green Homes Wales interest-free finance
The Green Homes Wales scheme can help eligible Welsh homeowners fund energy-efficiency and low-carbon improvements. It is a finance route managed by the Development Bank of Wales, not a grant and not a loan offered by Renewable Future Wales.
Published Green Homes Wales finance details
£1,000–£25,000
Published interest-free loan range
Up to 10 years
Published repayment term; larger projects may differ
0% interest
Subject to the current scheme terms and approval
The official page also describes a six-month upfront repayment holiday. All figures, terms and availability can change, so check the official scheme guidance before making decisions.
The published Green Homes Wales information describes an unsecured fixed-sum loan with no interest under the scheme terms. It is not free money, and it does not mean every applicant will be approved.
Applications are subject to affordability and credit-score checks. The Development Bank of Wales makes the lending decision, not RFW.
Development Bank of Wales: manages the scheme and decides applications for finance.
Renewable Future Wales: can discuss your renewable-energy needs, assess the installation and prepare a quote. We are not the lender and do not promise eligibility or approval.
You: apply through the official route and remain responsible for checking the current requirements before committing to work or borrowing.
Renewable improvements the scheme lists
The Development Bank of Wales terms list the following eligible measures. The official assessment and scheme guidance determine what can be funded at your home.
Heat pump top-ups are described as net of the Boiler Upgrade Scheme (BUS). BUS eligibility is a separate question and is not replaced by this finance route.
- You are a homeowner and the property is your primary, owner-occupied residence
- The property is in Wales and is not a business or business asset
- The property is not a new build that has not previously been occupied in the six months before applying
- You pass the scheme's affordability and credit-score checks
- The property is not a listed building — the scheme does not currently support listed buildings
- Conservation-area properties that require additional permissions for the work are excluded; contact the Development Bank of Wales to confirm your property
The current loan terms require a TrustMark-registered Retrofit Coordinator and a TrustMark-registered installer for the eligible measures. The installer must remain registered until the work is complete.
The scheme does not currently support listed buildings. Conservation-area properties that require additional permissions for the eligible works are also excluded under the current terms.
Guarantees, insurance, planning permission and other consents may also be required. Confirm your property's eligibility through the official scheme process before committing to work.
How the customer journey works
RFW can help with the installation conversation, but the official finance process belongs with the Development Bank of Wales.
1. Call Nest first
The Development Bank of Wales says Step 1 is to contact Nest (0808 808 2244) for free and impartial general advice on current support options before registering interest.
2. Register your interest
Use the Development Bank of Wales Green Homes Wales page to register interest and request the next stage of the home-assessment process.
3. Review your recommendations
A TrustMark-registered Retrofit Coordinator supports the home assessment. You then choose which eligible measures to take forward and gather quotes.
4. Apply to the lender
You apply to the Development Bank of Wales for finance. Its affordability and credit checks decide whether lending is approved; RFW cannot approve it.
5. Arrange installation
After the official process and any required approval, agree the installation with an eligible installer and follow the scheme's payment and evidence requirements.
The Welsh Government says Nest can confirm whether eligible households may receive a package of free home energy improvements, such as a heat pump, insulation or solar panels. The current eligibility route includes owning or privately renting, a means-tested benefit or low household income, and the required EPC conditions.
If you are unsure, contact Nest directly for impartial advice and to check your circumstances. Do not assume that a Nest assessment or Green Homes Wales finance is available until the official team confirms it.
