SSIP Accreditation via Once For All
Mellor & Co is pleased to confirm we have been independently assessed and approved for Health & Safety accreditation via Once For All, the new name for what was previously known as Acclaim Accreditation.
This important certification falls under the SSIP (Safety Schemes in Procurement) umbrella, the UK’s recognised standard for demonstrating health and safety capability in procurement processes.
As a certified business, Mellor & Co has successfully demonstrated that our policies, procedures, and on-site practices meet the core health and safety criteria required by public and private sector clients across the UK.
“In an industry where safety underpins every phase of delivery, this accreditation is more than a formality, it’s a statement of our commitment to protecting people, property, and reputation.”
– Tom Mellor, Company Director
What is SSIP and Why Does It Matter?
SSIP streamlines health & safety prequalification, giving buyers confidence that contractors meet legally compliant, risk-aware safety standards without duplicating checks across different schemes.
By achieving SSIP through Once For All, we:
Provide a transparent record of our health & safety management
Minimise compliance burdens for clients during tendering
Ensure site teams follow best practice protocols at all times
Strengthen our ability to deliver projects safely and responsibly
You may previously have seen this accreditation listed under the Acclaim name. In 2024, Acclaim formally rebranded as Once For All Health & Safety to reflect its wider commitment to integrated supply chain assurance. While the name has changed, the standard remains the same: SSIP-backed, independently verified, and recognised by clients nationwide.
Peace of Mind for Principal Contractors and Procurement Teams
For clients, our SSIP accreditation through Once For All means added peace of mind that Mellor & Co:
Works safely and in compliance with CDM 2015 regulations
Maintains up-to-date risk assessments and method statements (RAMS)
Takes a proactive approach to site safety, training, and supervision
This accreditation supports our role as a reliable, safety-conscious contractor, especially when working under principal contractors on large-scale commercial and residential schemes.
