Health and Safety Executive (HSE) information

The HSE is a good source of information and guidance. It has produced the key publication Managing health and safety in construction - Construction (Design and Management) Regulations 2015 - (L153) on the legal requirements for CDM 2015.

On the HSE website there are also some very useful Frequently Asked Questions pages. These are not formal HSE guidance and are not intended to cover every aspect of the topic or be a ‘one size fits all’ answer, but provide consistent and helpful answers to some of the most common questions which have arisen about CDM 2015. 

For further information see the HSE construction webpages, which includes a short client leaflet and a Busy Builder construction phase plan template for small projects (CIS80).
