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.

Implementation advice

Implementation advice and equipment procurement support to help you find reputable suppliers who will install appropriately specified equipment for your business needs.  Designed to support businesses with a specific energy saving project in mind (e.g. lighting), your organisation can receive up to 5 days of support from a Carbon Trust consultant – at no cost to your business.  This is available for companies with up to 1,000 employees in England, Scotland or Wales.

Specific help available includes:

  • A feasibility check
  • Writing performance specifications appropriate for your business
  • Tendering support, including supplier identification and assessment of tenders.

We will help you to find suppliers who can provide detailed quotes and who have been proven to deliver energy saving projects in the past.   Read more about how implementation advice can help you (PDF)

Implementation advice can also act as a gateway for your business to receive up to £10,000 capital contribution or 30% of the purchase cost of the energy saving equipment.

A series of workshops are planned to help small businesses work out how best to identify the energy saving opportunities available to them. Our advisers will be running these workshops with small groups of local businesses (aimed at companies with fewer than 50 employees) to show them how to make the most of this opportunity.

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

A financial contribution towards your energy saving equipment

The Carbon Trust Green Business Fund is offering a capital contribution of 30% of the project cost (up to a max of £10,000) to small and medium sized businesses, who could benefit from financial support when buying energy saving equipment.

This could mean up to £10,000 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 £2,500, and equipment should be purchased from a Green Business Directory supplier or a BESA Supplier, to ensure that your supplier is properly accredited.

*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.

The capital contribution

  1. 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.
  2.  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.
  3. Applications for the capital contribution must be approved prior to purchase and installation of the equipment.
  4. The applying company will receive the capital contribution upon completion of the project and issuing of a commissioning certificate.
  5. 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.
  6. 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.

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 working with the Carbon Trust Accredited Suppliers listed on the Green Business Directory or BESA Suppliers. 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.

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

We encourage companies to combine as many projects as possible into one application, this is to make the process as straightforward as possible and we would then be able to provide a 30% capital contribution on the total project value. Please note, we can accept more than one application and each company can access up to £10,000 in capital contribution, in total. 

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.
