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

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.

The CHAS Assessment

  • The assessment is carried out as a desktop assessment, there are no visits to your office or site, so it is important that when you submit your application you include all supporting documents and evidence.
  • CHAS assessment is a simple process. Our assessors will do all they can to advise you as to what is needed to achieve compliance.
  • It is not unusual for suppliers to receive an initial failure letter or a request for further information. You will be told what needs to be improved and have the opportunity to reapply within a mutually agreed time scale.
  • A fundamental principle of our scheme is to help any supplier improve their safety management should they fail.
  • In exceptional cases, if the policy or arrangements are poor, you may be directed to seek competent health and safety advice.
  • When tendering to one of our buyers, you should note you will not be short-listed if your status in CHAS is ‘failed’, ‘failed to resubmit’ or ‘Withdrawn Non Payment’.
