Agreed. A re-write of CDM 2015 may help SME's, albeit that larger Conglomerates are having no trouble with compliance as it is relatively straightforward.
SME's (if pro-active) have access to huge amounts of HSE advice for free largely but many choose the route of ingorance in this regard.
The CPP template is probably the simplest document ever produced and yet it is once again largely ignored by SME's. Why ?
