Construction (Design and Management) Regulations 2015 (CDM 2015)
Subject to Parliamentary approval, new Construction (Design and Management) Regulations 2015 (CDM 2015) will come into force on 6 April 2015.
Regarding the transitional arrangements concerning CDM 2015, please go to http://www.hse.gov.uk/construction/cdm/regulation-changes.htm.
When CDM 2015 comes into force on 6 April 2015, there will be a transitional period that will run for six months from 6 April 2015 to 6 October 2015.
For projects starting before 6 April 2015, where the construction phase has not yet started and the client has not yet appointed a CDM co-ordinator, the client must appoint a principal designer as soon as it is practicable.
If the CDM co-ordinator has already been appointed, a principal designer must be appointed to replace the CDM co-ordinator by 6 October 2015, unless the project comes to an end before then.
