SSIP Mutual Recognition (Deem to Satisfy) Explained

Deem to Satisfy means a valid SSIP certificate from one member scheme is accepted by the others without a fresh assessment. Hold one SSIP-approved scheme and you generally don't need a second — even if different clients name different schemes. But the recognition has specific limits, and knowing them saves you both money and a re-assessment you didn't need.

How Deem to Satisfy works

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. Usually they will.
3. 3
   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.

The limits that still catch people out

Deem to Satisfy is powerful but not unlimited:

Why this is the honest case for a tool

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 members without re-assessment, so you usually don't need to be assessed twice for the same health & safety.

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.

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, or the Common Assessment Standard. For those, you need a scheme tier that specifically includes them.
