Sustainable finance for a greener economy

Our Green Business Loan Scheme offers an incentivised funding package to support your business's decarbonisation journey.

Loans from £1,000 to £1.5m are available, as well as expert advice and funding for energy consultancy.

Typical projects that are eligible for funding through the Green Business Loan Scheme are:

  • Heating, ventilation and air conditioning – replacement, management, low carbon technology
  • Building fabric improvements – insulation, double glazing, LED lighting
  • Renewables – solar PV, ground/air/water source heat pumps
  • Key equipment improvement – monitoring and controls, replacement, low carbon technology
  • Water usage and waste reduction/improvements

Businesses that deliver green services and products can also apply for finance to help start-up, strengthen or grow.

Property developers can enjoy reduced lending costs on new housing schemes that deliver more thermally efficient and lower carbon homes in Wales through our Green Homes Incentive.

Through the Welsh Government's Local Energy Fund we can provide development and capital finance for community-led low carbon and renewable energy projects that will provide economic, social and environmental benefit to local areas across Wales.

We're committed to addressing the climate change emergency and continue to develop ways of working that will have direct impact, driven through:

  • Ongoing delivery of a carbon reduction plan focused on our own operations through a dedicated working group with the ambition to reach net zero.
  • Utilising our research unit Economic Intelligence Wales to explore policy and product recommendations to inform the transition to a low carbon economy.
  • Supporting the businesses we work with to improve and reduce environmental impact including through referrals to Business Wales sustainability advisers. 

We create long-term financial and social value by using the capital we raise, the people we employ and our relationships with stakeholders and the business community.


We promote fairness, accountability, responsibility and transparency in our own operations and those of our suppliers, partners and the businesses we support.

We strongly believe in investing responsibly and ethically, and as such we are a proud signatory of the Principles of Responsible Investment.
