Green Business Loan Scheme: Funding Solar & Energy Upgrades for Welsh Businesses

Looking to Cut Energy Costs with Solar?

Rising energy prices are putting pressure on businesses across Wales. Investing in solar PV and energy efficiency is one of the most effective ways to reduce operating costs and protect your business from future price volatility.

The Green Business Loan Scheme makes that transition more accessible—combining expert guidance, grant support, and affordable finance to help you install solar and other low-carbon technologies.

What is the Green Business Loan Scheme?

The Green Business Loan Scheme is a Welsh Government initiative designed to help businesses reduce carbon emissions while saving money on energy.

It supports your journey from initial idea, planning, installation to long-term savings, addressing the most common barriers:

• Not knowing where to start

• Lack of time to research options

• Uncertainty around return on investment

• Limited access to funding

  
  

How the Scheme Supports Solar Projects

If you're considering solar panels for your business, this scheme can support you at every stage:

1. Fully Funded Energy Advice

Work with a Business Wales advisor to:

• Assess your current energy usage

• Identify solar suitability and savings potential

• Build a clear, tailored action plan

2. Grant Support for Detailed Assessments

For more complex projects, you can access:

• Up to 50% funding for a professional energy audit

• Maximum grant of £10,000

• Independent experts to validate your solar opportunity

3. Affordable Finance for Installation

Once you're ready to proceed, the scheme offers:

• Discounted fixed interest loans

• Repayment terms linked to your energy savings

• Initial repayment holidays to ease cash flow

This makes solar installations far more accessible, often allowing projects to be cash-flow positive from an early stage.

Why Solar Works So Well with This Scheme

Solar is one of the most financially viable upgrades under the Green Business Loan Scheme because:

• Immediate bill reduction – generate your own electricity

• Predictable returns – long-term energy savings
