Carbon Trust Accredited Suppliers have met or exceeded criteria set by the Carbon Trust designed to examine their capability to deliver thoughtful, well-designed energy efficient and renewable energy systems. As part of the assessment process, the Carbon Trust takes into consideration feedback from client references regarding the suppliers’ performance. Whilst the Carbon Trust has endeavored to confirm that all suppliers included in the Green Business Directory are of a proven high quality, users of the Green Business Directory enter into contracts directly with Accredited Suppliers to the exclusion of the Carbon Trust, and at their own risk. The Carbon Trust makes no representations regarding, nor does it accept any liability whatsoever in respect of, the performance of any services or the supply of any goods by Accredited Suppliers. Case studies have been written and supplied by Accredited Suppliers. Details should be independently reviewed by prospective customers.
