ARCHIVED: This Practice Note has been archived and is not maintained.
The Construction (Design and Management) Regulations 2015, SI 2015/51, (CDM 2015) govern the management of health, safety and welfare on construction projects in the UK. CDM 2015 has replaced the Construction (Design and Management) Regulations 2007, SI 2007/320 (CDM 2007).
CDM 2015 came into force on 6 April 2015. From that date, CDM 2007 and its associated Approved Code of Practice are no longer in force.
On coming into force, CDM 2015 applied to both new and existing projects. However, from 6 April 2015 until 6 October 2015, transitional arrangements were in place which applied to certain projects already in progress, see Practice Note: CDM 2015—transitional provisions [Archived]. This Practice Note examines in detail how CDM 2015 compares to CDM 2007. For a summary of the differences, please see CDM Regulations 2015 vs CDM Regulations 2007 [Archived].
