The Contractors Health and Safety Assessment Scheme

Follow us on:

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

Kings Security (Full Application)

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.

Greens Decorating Contractors Ltd, 2015.

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 so of these things could get forgotten about, so would cost my company in contracts in the future.

T Brown Joiners, 2014.

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.

Ecological Land Management Ltd, 2014.

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.

MA Brickworks Ltd, 2014.

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.

Probe Lockers, 2014.

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.

Autism Hampshire, 2014.

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.

CHAS is pleased to announce the launch of our Electronic application system (Eforms)

We are pleased to announce that our new Eforms system is now live.

Eforms is an electronic application system which allows you to submit a CHAS Assessment with supporting documentation online.

If you have been registered with CHAS before and you’re a returning Supplier you can login with your “Accredited Contractors ID” (Your Accredited Contractors ID would have been supplied upon completion of your last assessment. Please click here if you have forgotten your Login ID).

Alternatively if you are a new Supplier you can apply for an assessment using Eforms and it will allocate you a login ID.
