SSIP Mutual Recognition (Deem to Satisfy) Explained

How does SSIP Deem to Satisfy work?

According to the SSIP Deem to Satisfy guidance, every SSIP member assesses against the same SSIP Core Criteria. So when you already hold a valid certificate, another member can issue you a Deem to Satisfy certificate instead of re-running the full assessment — provided your original certificate shows correctly on the SSIP Portal. SSIP reports over £10 million saved in 2023 through this reduced duplication.

1. 1
   Get your first SSIP certificate from any member scheme that suits your size and budget — see the comparison hub.
2. 2
   When another client names a different scheme, ask whether they'll accept your existing SSIP certificate under Deem to Satisfy. In most cases, clients named by Registered SSIP members (CHAS, SafeContractor, SMAS) accept Deem to Satisfy certificates for health & safety; however, certification body certificates (BSI, Bureau Veritas) face one-way limits as outlined below.

   If you do need the second scheme on record, apply for its Deem to Satisfy route and present your original certificate — not a full re-assessment.

What are the limits of SSIP mutual recognition?

Deem to Satisfy is powerful but not unlimited:

Why do you still need a tracking tool if schemes recognise each other?

Mutual recognition removes the duplicate assessment — but it doesn't remove the admin around it. You still have to track each scheme's annual renewal date, keep the underlying evidence documents current, re-supply them to each new client PQQ, and handle the bits SSIP doesn't cover. That residual tracking — not the assessment itself — is the real, ongoing pain.

Frequently asked questions

Do SSIP schemes recognise each other?

Yes, for the core health & safety assessment. Under Deem to Satisfy, a valid SSIP certificate from one Registered Member is accepted by other Registered Members without re-assessment, so you usually don't need to be assessed twice for the same health & safety. Certification Body certificates (BSI, Bureau Veritas, SGS) are recognised one-way by Registered Members but not between two Certification Bodies.

Can I avoid paying for two accreditation schemes?

Often, yes. If you already hold a valid SSIP certificate, ask a new client to accept it under Deem to Satisfy rather than buying a second full membership. You may still choose a second scheme for its other benefits (like a directory listing), but you shouldn't pay for a duplicate health & safety assessment. The recognition is automatic for Registered Members and must be requested from Certification Bodies.

What doesn't Deem to Satisfy cover?

It covers health & safety only. It does not cover financial or professional standing checks, environmental or CSR assessment, quality management systems, or the Common Assessment Standard. For those, you need a scheme tier that specifically includes them — or a separate accreditation like ISO 9001 or 14001.

Can I use a Deem to Satisfy certificate to get another?

No. SSIP's recognition rules require your original assessment certificate, not a Deem to Satisfy copy. You cannot chain one DtS certificate to obtain another. All subsequent Deem to Satisfy applications must reference the same original third-party assessment.

What renewal deadlines do I still need to track?

All of them. Deem to Satisfy removes the duplicate assessment, but each scheme still has its own annual renewal date, membership fee, and evidence upload portal. You must track and renew each scheme separately, even if they all recognise the same underlying health & safety certificate. See accreditation renewal deadlines for a complete tracking guide.

Is Deem to Satisfy two-way for all schemes?

No. Registered Members (CHAS, SafeContractor, SMAS, Once For All) offer two-way recognition — they accept each other's certificates. Certification Bodies (BSI, Bureau Veritas, SGS) are one-way only — their certificate is recognised by Registered Members, but not between two Certification Bodies. If you hold a Certification Body SSIP certificate and need another Certification Body scheme, you will need a fresh assessment.
