Energy opportunity assessment

The Carbon Trust are offering energy opportunity assessments to small and medium sized businesses to help them identify energy saving opportunities, and to develop a robust business case for the purchase of the appropriate equipment (for further details on who can apply see our FAQs). Carbon Trust may provide this support remotely via telephone and email, or on-site.

These services are paid for by the Green Business Fund for a limited period.

Following an energy saving opportunity assessment, for those businesses wanting to improve their energy management practices, further support may be available through our Virtual Energy Manager to help implement a range of energy management activities from;

  • implementing an energy policy to
  • identifying the best ways to engage employees.

The Virtual Energy Manager is targeted at SMEs with an energy spend of over £50,000 and will be delivered remotely through a series of support modules delivered by a Carbon Trust expert.

The Carbon Trust’s energy assessment has been very useful in helping the business identify further ways that we can reduce our carbon footprint, and also reduce energy costs.

A financial contribution towards your energy saving equipment

Please note, we are no longer accepting new applications for the capital contribution. The Carbon Trust Green Business Fund is offering a capital contribution of up to 15% of the project cost (up to a max of £5,000) to small and medium sized businesses, who could benefit from financial support when buying energy saving equipment. 

This could mean up to £5,000 towards a new lighting system for your warehouse, heating and air conditioning equipment for your offices or a controls system for your factory - to help you rise to the challenge of becoming a greener business.

This support is available for a limited period on a first come, first served basis for small and medium sized businesses in England, Scotland and Wales (for further details on who can apply see the How to apply for a capital contribution (PDF) document). The minimum total size of the project must be £5,000, and applicants should be contracting the entire project directly with a Green Business Directory supplier or a BESA Supplier, to ensure that your supplier is properly accredited. 

Applicants for a Green Business Fund capital contribution must be in receipt of a capital contribution offer prior to contracting a supplier to install the equipment - we cannot retrospectively fund energy efficiency projects that have already been contracted - this is to ensure that the project selected has been assessed by the Carbon Trust as optimal for your business.

Businesses in Wales can take advantage of both the Green Business Fund and the Wales interest free energy efficiency loans scheme. SMEs in Scotland can also apply for the Resource Efficient Scotland interest free SME loan.

*subject to criteria; terms and conditions apply


What companies can apply into the Green Business Fund?

The Green Business Fund is an energy efficiency support service aimed primarily at small and medium-sized companies (SMEs) in England, Wales and Scotland. SMEs are defined as such if they meet 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.

Do you help with funding for public sector and domestic energy cost reductions?

The Green Business Fund is open to Small & medium sized businesses, Charities, Schools, and Sole Traders who meet the scheme criteria.  Public sector, domestic properties and new builds are not eligible for support from the Green Business Fund. 

The capital contribution

Please note, we are no longer accepting new applications for the capital contribution. 

  1. The minimum project cost must be £5,000 with a payback period of 5 years in order to be eligible for a capital contribution.
  2. In order to apply for the capital contribution, you would need to be replacing equipment you currently own with energy efficient equipment where the savings can be clearly defined. We will look to fund projects where the payback period on energy savings is within 5 years.
  3. If you have a project that provides energy savings that will pay back in over 5 years, then we will fund the relevant contribution on the first five years’ worth of energy savings.
  4. Applications for the capital contribution must be approved prior to purchase and installation of the equipment.
  5. The applying company will receive the capital contribution upon completion of the project and issuing of a commissioning certificate.
  6. The capital contribution is a private contribution to provide an incentive for the purchase of energy efficient equipment. It works in a separate way to the Carbon Trust loans, and therefore does not need to be paid back over time.
  7. The capital contribution cannot be used to part pay for work that has already been completed and installed prior to the application being made to the Carbon Trust Green Business Fund.

Companies must meet the SME criteria, as defined in ‘What companies can apply into the Green Business Fund’. For companies who are part of a group structure, the total maximum entitlement is £5,000 across the group.

In order to receive the capital contribution your company must be trading for a minimum of 12 months.

Please note, we have now closed for new applications for the capital contribution. 

To contact us for further advice on applying to the Green Business Fund please call 020 7832 4773 or email

Are there certain suppliers we can work with?

In order to qualify for funding, businesses must be contracting the entire project directly with a Carbon Trust Accredited Supplier listed on the Green Business Directory or a BESA Supplier. The Carbon Trust wants to ensure that all projects implemented through the fund are of a high quality which will help them meet the projected savings. Because Accredited Suppliers are assessed against qualitative criteria, both the customer and the Carbon Trust can have confidence in the success of the project, and that the solution is well designed and fit for purpose.

We welcome applications from new suppliers to become accredited on the Green Business Directory.

How do I find if a supplier/installer is on the list?

You can check if a supplier is listed on the Green Business Directory of Carbon Trust Accredited Suppliers.

Can a company apply into the scheme on more than one occasion?

A business can apply for multiple capital contributions, to the maximum of £5,000 in total.

We have just recently installed some energy saving equipment, is this something you would help with?

No, unfortunately we are not able to provide funding towards projects after installation.

Is there any financial obligation with the services?

All services (WorkshopsEnergy opportunity 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 fund recipients are able to do so.
