How to find financial support for energy efficiency upgrades

Businesses and organisations often struggle to pay for energy efficiency upgrades to cut energy bills and reduce carbon emissions. We’ve put some information together to help get you started with finding financial support.

Please note: If you decide to apply to a funder for a grant or loan always check with the specific website regularly for any changes to criteria, deadlines or for any additional advice or information that has been posted. This page was last updated in February 2023.

Embarking on an energy efficiency project can be costly, and many businesses and organisations struggle to find the capital to fund their plans no matter how much impact they could have on reducing carbon emissions.

Where to start

Before applying for any loan finance, you should speak with an independent financial adviser to see whether a green loan is suitable for your business.

Many grants and loans are location specific and it’s often best to:

  • Contact your local authority. Your local council may have grants or loans available.
  • Contact your energy supplier. Many offer small loans and grants for businesses to improve energy efficiency.
  • Search online resources like Grants Online to see what’s available in your local area.
