Want to reduce your energy usage?

This is the best place to start if your organisation wants to reduce its energy costs, but you don’t know where to begin. We offer fully funded energy assessments at no cost to your business to help identify areas for energy and cost savings.

This service is provided either remotely (via telephone and email) or in person on-site, depending on your location and energy spend.

A Carbon Trust expert will produce a bespoke report for your organisation identifying the top three energy and cost savings projects for your business. They can also advise you on how to implement an energy policy, and suggest ways to engage your employees.

Want help finding suppliers and quotes? 

This service is perfect if you have already identified particular energy saving projects that you’d like to undertake.

Specific help available includes:

  • A project feasibility check
  • Help writing performance specifications appropriate for your business

We provide up to 5 days of funded, bespoke support from a Carbon Trust consultant at absolutely no cost to your business.

What organisations are eligible for support?

The Green Business Fund is open to small & medium sized businesses, charities, schools, and sole traders in England, Wales and Scotland who meet the scheme criteria. 

Organisations must meet at least two of the three following criteria:

• No more than 250 employees;

• Annual turnover not in excess of £25.9m; or

• Annual balance sheet not in excess of £12.9m

and if they are not more than 25% owned by an entity which does not meet the criteria.

Franchises are also eligible providing they have a different registered company number and are a separate legal entity to their managing partnership.

Please note, any organisations with fewer than 1000 employees are eligible for Implementation Advice. 

Do you support public sector and domestic energy cost reductions?

Public sector, domestic properties and new builds are not eligible for support from the Green Business Fund. 

How do I find if a supplier/installer is Carbon Trust accredited?

You can browse the suppliers of energy efficient equipment listed on the Green Business Directory of Carbon Trust Accredited Suppliers. If you're a supplier who's interested in becoming accredited, you can find out more and apply here.

Is there any financial obligation with the services?

All services (WorkshopsEnergy Assessments and Implementation Advice) are fully funded through the Green Business Fund so will carry no cost to the applicant. There is also no obligation for each company to follow through with any of the energy saving opportunities identified to them, though of course we hope that all organisations are able to do so.

Do you have any grants available?

Unfortunately we are no longer accepting new applications for the capital contribution grant funding. If you're based in Wales, we may be able to offer an interest free loan for energy efficiency projects. Find out more here.

We're constantly on the lookout for further funding opportunities. If you'd like to be the first to hear about any funding that may be available in the future, please get in touch with the team at
