The Work at Height Regulations 2005 came into effect on the 6 April 2005. The Regulations will apply to all work at height where there is a risk of a fall liable to cause personal injury. There are now no height limits. The Regulations place duties on employers, the self-employed, and any person that controls the work of others (for example Building Managers, Property Services and others who may contract others to work at height, such as window cleaners and builders). The Regulations do not apply to the provision of paid instruction or leadership in caving or climbing by way of sport, recreation, team building or similar activities.
