The Carbon Trust Accredited Supplier scheme is the UK’s market-leading scheme for high quality energy efficient equipment and renewable technology suppliers.
The Carbon Trust Accredited Supplier scheme provides independent validation and recognition of a supplier's skills and services - a much needed and trusted quality standard in a crowded and fast growing market place.
Accredited Suppliers must meet or exceed criteria set by the Carbon Trust designed to examine their capability to deliver thoughtful, well-designed energy efficient and renewable energy systems. Only Carbon Trust Accredited Suppliers are included in the Green Business Directory.
Companies that are approved for accreditation are able to benefit from the following when referring to the technology they are accredited for:
As a widely recognised and trusted name in the energy efficiency sector, we feel that Carbon Trust Accredited Supplier status provides us with a helpful differentiator in the market place.

Please read the FAQs below before applying.
The scheme is designed to help businesses wanting to implement energy saving projects to select suppliers with a proven track record in designing, supplying, implementing and commissioning energy saving projects. This is to provide the end customer with confidence that the predicted energy, carbon and cost savings will be realised.
The scheme is open to energy saving equipment suppliers who offer a full end-to-end service to their customers in the UK (design, supply, fit, commission). Suppliers must be able to demonstrate that they have been successfully trading for a minimum of 12 months. Unfortunately we cannot accept applications from sole traders. We only accredit the very best suppliers who deliver good quality energy saving projects for their customers. The application process is about proving a track record of delivering such projects.
Following completion and submission of the Accredited Supplier scheme application form the accreditation process proceeds through the following four steps:
• Step 1 - Review by the Carbon Trust Accredited Supplier team of the fully completed application form and all company information submitted
• Step 2 - Credit check to ensure that the company is a stable, going concern (where published accounts are not available, evidence of financial stability will need to be provided)
• Step 3 – Review of the in-house technology capability, energy saving expertise and customer service approach through a structured telephone call with each contact reference provided for a minimum of three UK case study examples
• Step 4 - A 30 minute telephone interview with a Carbon Trust technical representative covering your in-house technology expertise, pre and post sales processes and insurance and quality assurance documentation.
Unsuccessful applicants will be informed by the Carbon Trust team, and will be notified of the criteria which have not been met / evidenced. Carbon Trust is committed to dealing with appeals in a fair and impartial manner, as detailed in our Appeals Process (PDF).
On receipt of a fully completed application form, the accreditation process typically takes 3 to 4 weeks to complete.
To ensure that your application proceeds as quickly as possible please ensure that your case study referees are aware that they will be contacted by a member of the Carbon Trust team. Failure to do this will result in delays to your application.
Following completion of initial administration checks including case study checks, the technical interview will be scheduled for a mutually convenient time.
Should you successfully pass the accredited supplier scheme interview, your accreditation will be listed on the Green Business Directory within 5 working days following receipt of payment of the accreditation fee.
If you subcontract some activities within the delivery process to a third party please make this clear on your application form. Please evidence how this interaction works and the steps taken to ensure that all third party delivery meets required quality standards.
The case studies provided as part of your supplier scheme application should evidence your technology expertise and track record in delivering energy saving projects in the UK. This includes:
• 'old' system/equipment;
• design rationale/approach for the new system;
• details of new equipment/system;
• completion date;
• project cost;
• annual savings (expected/actual if known);
• simple payback period; and
• client’s full contact details (we will contact each client to receive their feedback on the project).
The contacts put forward must be available and prepared to speak to a Carbon Trust representative in a structured telephone call. Do therefore give consideration to the projects that you put forward. There should be a minimum of three UK case studies, and a minimum of one case study per technology for which you are applying for accreditation.
