Aardvark Certification Limited


Aardvark Certification Limited (ACL) is a respected and specialist auditing and certification body. Born from a successful, established environmental consultancy firm, ACL was created to provide a fully independent and impartial auditing and certification body to the energy and waste sector with in-house technical experts.

Our expertise lies in the treatment of biowastes, primarily composting and anaerobic digestion.  We are experienced professionals with our core staff having 15+ years’ experience in the composting and AD sectors.

We hold ourselves to the highest standards and are currently in the process of gaining UKAS accreditation to the Compost Certification Scheme and the Biofertiliser Certification Scheme provide our clients with absolute confidence in the level of service they can expect to receive.

ACL are uniquely positioned to have extensive auditing experience and technical knowledge meaning their Lead Auditors are able to carry out all aspects of our auditing and inspection work independently without requiring input from 3rd party technical experts. This helps them to deliver value for money to clients whilst maintaining control over delivering the level of service.

ACL produce assurance reports in accordance with the International Standard for Assurance Engagements 3000 (ISAE 3000 (Revised) and have carried out many Ofgem Sustainability Audits for clients over the last few years. ACL are happy to discuss combined audit pricing if you require more than one auditing service.

ACL work with clients from a range of backgrounds including commercial composting operations, farm-based biogas plants to large scale commercial biomethane producers.

From their offices in Somerset and London, ACL provide a full service to all parts of the UK including Northern Ireland, the Isle of Man, and the Channel Islands.
