The Contractors Health and Safety Assessment Scheme

This certainly seemed to prove an easier and more painless way to attain our accreditation.

The new process was clear, very quick and easy to use.I would not hesitate to use this service when our accreditation comes up for renewal next year.

A high percentage of new business is generated through successful tenders. Over the years the number of lead contractors that make CHAS registration a prerequisite in the tendering stage has risen substantially. One of our biggest customers accepts CHAS as an alternative to having to go through their own health and safety questionnaires. This allows us to streamline our tendering process to maximise the number of projects we can work on.

With my company being small, the assessment works well for me, but also keeps me up to date with all my H&S. Without using CHAS some of these things could get forgotten about, so would cost my company in contracts in the future.

Joining CHAS really made us consider out H&S procedures in more detail and having to document them all instantly makes them easier to maintain and renew.

CHAS is a great service which has helped my company become better and which has resulted in us winning more contracts of work. I have also recommended CHAS to other companies I work alongside who have now also become CHAS accredited.

The accreditation process itself is a great way of monitoring the H&S within your own company, so by itself forces training in areas you may not be familiar with, so money well spent.

I would just like to thank you for your help and expertise throughout this whole process. My experience with CHAS was great from start to finish.

We first achieved our CHAS accreditation in 1998 and have found it very useful as a means of demonstrating that we comply with current health & safety law in the construction industry. CHAS is recognised across the whole of our industry so it reduces the amount of time and resources needed to pre-qualify for projects.

Safety Schemes in Procurement (SSIP)

The CHAS management team are pleased to announce their founder membership status of the SSIP. More detail can be found on the SSIP website What this page aims to provide is some brief background information to CHAS' involvement in the Forum and what it means to our members (buyers) and our registered contractors and consultants - the suppliers.

SSIP Mission Statement

"Our mission is to act as an umbrella organisation to facilitate mutual recognition between health and safety assessment schemes wherever it is practicable to do so"

What does CHAS have to do to be an SSIP Member?

For us to achieve and maintain our SSIP registration we, like other schemes - including new ones as they join - must demonstrate and maintain the standards required by HSE through an annual independent third-party audit. The audit is in two parts, we must demonstrate quality management to ISO 9001 standard and health and safety pre-qualification to the HSE approved standard.

What can client users (buyers) expect?

An important feature of SSIP is the HSE’s message that a buyer can be confident a supplier who is registered or accredited as compliant or approved with an SSIP member has been assessed to the threshold standard (stage 1). The buyer having verified their status will only then need to focus on the project or job specific assessment (stage 2). When tendering for work many existing CHAS buyers require suppliers to be CHAS registered and will advertise “CHAS or equivalent”. If a supplier tenders for work with a buyer as an ‘equivalent’ you need not ask them to register with CHAS - simply accept their SSIP equivalence, having first verified with the SSIP scheme member that it remains valid. Of course from a supply chain management point of view, you may wish to have the supplier register with CHAS.

Non-CHAS scheme registered buyer.

A supplier registered with CHAS may give you a copy of their CHAS registration letter, their certificate of accreditation or their database user ID. You should contact us by email ( and we will verify their status with you as soon as we can. Remember that any further assessment on this supplier by you, needs to only focus on the second stage (project or job specific) assessment. If you wish to have access to the audit trail and history of this supplier you may consider joining the CHAS scheme (there is no cost to you). By accepting CHAS compliance as a ‘deem to satisfy’, both you and the supplier will save time and resources. The supplier won’t have to complete an application and provide evidence and you won’t have the time consuming task of assessing it.

CDM 2015

SSIP assessments are all judged on core criteria approved by HSE. These core criteria describe what it means for a construction business to comply with basic health and safety law. The Core Criteria were published by HSE in Appendix 4 of the CDM 2007 Approved Code of Practice. With the new CDM 2015 Regulations, there is no immediate publication of an Approved Code of Practice, and the SSIP Forum have agreed to adopt the Core Criteria to become part of the SSIP Rules and Bylaws.

What can CHAS registered suppliers expect?
Registration with other scheme members

‘Deem to satisfy’ may not always be fully reciprocated amongst all SSIP members. Exor Management Services accept CHAS fully but have some additional criteria that is required by the client. Constructionline will accept an SSIP registration in full, but as they do not carry out assessments themselves, it cannot be reciprocated. The service levels for existing members (buyers) and new ones as they join are described in detail on the SSIP web site at

By all supply chains

Suppliers should not expect everyone to accept ‘deem to satisfy’ overnight. There are many supply chain managers who will need to be convinced they can place their trust in what we are doing. However, suppliers have a role to play when asked to complete a health and safety PQQ by a non-SSIP member. As a CHAS registered supplier please ask the buyer if they know about the SSIP Forum. If they do not, ask them to consider visiting the web site at where they will see this HSE supported initiative. This means they can trust your third-party (CHAS) registration, which will save everyone valuable time and resources.

CHAS is fully committed to the principles of SSIP.

Only through schemes such as SSIP can the construction industry hope to reduce (the estimated) hundreds of millions of pounds wasted each year by procurers “doing their own thing” in health and safety prequalification.
