Being a member of CHAS ensures benefits to both TIS and our customers, it provides the reassurance that we are compliant with the most important parts of Health and Safety law (as described in the CDM regulations). From a buyer/customer’s perspective, assessing suppliers health and safety competence is usually a lengthy and time consuming process. Suppliers can sometimes meet one buyer’s Health and Safety standards but not another. Being CHAS approved reduces duplication as our compliance is accepted by all CHAS buyers.
