Our accreditations
ACCL holds a range of respected accreditations that reflect our commitment to quality, safety, compliance and technical professionalism across our operations. They give clients added assurance that our work is delivered to recognised industry standards, with the systems, procedures and expertise in place for consistent, dependable results.
Accountability and continual improvement
Together, these accreditations show our focus on accountability, continual improvement and high standards across the projects, environments and sectors we work in. Most are renewed through recurring external audits, so they reflect how we work now.
Standards behind the schemes
The ISO standards give recognised frameworks for quality, environmental and health and safety management. CHAS, SafeContractor and Constructionline help buyers check supplier competence, and SSAIB certifies CCTV and access control installers. Constructionline supports buyers by validating suppliers and aligning higher membership levels with the Common Assessment Standard.
