On 6 April 2015, CDM 2007 was revoked and replaced by the Construction (Design and Management) Regulations 2015 (CDM 2015). The CDM 2007 webpages will be retained until October 2015 .
If you are doing or having construction and building work carried out, you will have health and safety responsibilities to consider before starting work.
If you are having construction work done on your own home, or on the home of a family member, as a domestic client you do not have to notify the work to HSE and you will not have duties under CDM 2007 - although those doing the work on your behalf (such as designers or contractors) will.
If you are having construction work done as part of a trade or business, for example as a landlord or a developer, it may be notifiable and you will also have other duties as a client under CDM 2007.
Construction work is notifiable to the HSE if the construction phase is expected to last more than 30 days or 500 person days of construction work.
