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.

Greens Decorating Contractors Ltd.

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.

Ecological Land Management Ltd.

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.

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.
