# Building Lime Supply Accreditation

The main UK trade bodies and regulatory schemes relevant to building lime supply include the British Association for Chemical Specialities (BACS), membership of which signals quality and safety compliance, and accreditation through the Quality Assurance scheme operated by the Lime Centre at Bath. Some suppliers also hold BS EN ISO 9001 certification, which demonstrates they operate a quality management system meeting international standards. Additionally, the Environment Agency regulates waste-derived lime products under the Quality Protocol, ensuring environmental and performance standards are met. Individual lime products may carry CE marking under the Construction Products Regulation (CPR), indicating compliance with European harmonised standards for strength, durability, and safety. These credentials collectively reassure customers that a supplier meets consistent standards for product quality, environmental responsibility, and reliable service delivery.

To verify a provider's credentials, you should request copies of current certificates or accreditation documents and check these against the issuing bodies' registers, most of which are searchable online. The Lime Centre and BACS both maintain publicly available lists of accredited members. It is worth checking whether their accreditation covers the specific product type you need, such as non-hydraulic lime, natural hydraulic lime, or formulated lime mortar, since some credentials are product-specific. You should also ask suppliers directly about their accreditation status and request recent audit reports or compliance statements. Verification matters because accredited suppliers have undergone independent assessment, reducing the risk of receiving substandard products that could compromise structural integrity, fail to set properly, or cause compatibility issues with period or specialist building work. Accreditation also typically means better traceability if problems arise and easier recourse through formal complaints procedures.

Accredited building lime suppliers typically charge between 5 and 15 per cent more than unaccredited competitors, reflecting the costs of achieving and maintaining certification, regular aud
