Environmental health officers make sure that people's living and working surroundings are safe, healthy and hygienic.

They do this by investigating, monitoring and assessing the effects of environmental hazards – such as pollution, unsafe food and infectious diseases – on people's health and wellbeing.

They also ensure registered premises comply with regulations and grant licenses to them.
