We’re proud to share some fantastic news from the team at SL2! As part of our ongoing commitment to excellence, we’ve successfully achieved and renewed three major industry accreditations all of which are strengthening our position as a trusted and compliant partner across all construction sectors:
- CHAS Advanced Accreditation
- Constructionline Gold Membership
- BMTRADA Q-Mark Certification for Fire Door Installation & Maintenance

These certifications demonstrate our dedication to the highest standards in health and safety, governance, and fire protection; core values that guide every project we deliver.
First up is the renewal of our CHAS Advanced Accreditation
The CHAS (Contractors Health and Safety Assessment Scheme) Advanced accreditation confirms our strong health, and safety processes and demonstrates full compliance with relevant legislation. This provides reassurance to our clients that we operate with professionalism, risk awareness, and care across all environments.
Next up Constructionline Gold Membership renewal
Renewing our Constructionline Gold certification reflects a thorough review of SL2’s:
- Environmental and quality management practices
- Equality, diversity, and inclusion policies
- Anti-bribery, corruption, and modern slavery compliance
This accreditation further supports our reputation as a responsible and ethical contractor and opens new doors for public and private sector partnerships.
Finally, we’ve renewed our BMTRADA Q-Mark Fire Door certification
Being officially certified under the BMTRADA Q-Mark scheme confirms our capabilities to install and maintain fire doors to the highest industry standards. Fire safety is a critical aspect of any building project, and this accreditation ensures we deliver trusted, compliant solutions every time.
Why This Matters
These accreditations are more than just credentials, they reflect our deep investment in people, processes, and compliance. For our clients, they offer peace of mind that SL2 is fully qualified, independently verified, and always working to the highest professional standards.
