An EHO is an Environmental Health Officer, a professional employed by local government to protect public health by inspecting businesses, investigating complaints, and enforcing standards related to food safety, housing conditions, workplace safety, noise, and pollution. If you’ve ever wondered who checks whether a restaurant kitchen is clean or whether a landlord is ignoring dangerous mold in a rental property, the answer is usually an EHO.
What an EHO Actually Does
Environmental Health Officers cover a surprisingly broad range of responsibilities, all connected by one thread: preventing harm to people’s health from their surroundings. Their day-to-day work typically falls into a few core areas.
Food safety: EHOs carry out routine inspections of restaurants, cafés, takeaways, pubs, hotels, and food retailers. They check hygiene practices, food storage temperatures, pest control measures, and staff training. When a business fails an inspection, the EHO can issue improvement notices, and in serious cases, shut the premises down immediately.
Housing standards: EHOs inspect private rented homes when tenants report problems like damp, mold, faulty wiring, or dangerously cold living conditions. In England, councils use a system called the Housing Health and Safety Rating System (HHSRS) to assess how likely a hazard is to cause harm and how serious that harm could be, with extra consideration given to vulnerable groups like children and older people. EHOs can issue prohibition orders on overcrowded or unsafe properties. As of October 2025, landlords and housing associations in England must address emergency hazards within 24 hours and resolve serious damp and mold within 5 working days after investigation.
Noise and nuisance complaints: If a neighbor’s construction noise is relentless or a business is producing foul odors, the EHO is the person who investigates. They assess whether the disturbance qualifies as a statutory nuisance and can take enforcement action against the source.
Workplace health and safety: EHOs enforce health and safety rules in certain types of workplaces, including offices, shops, hotels, restaurants, pubs, clubs, leisure facilities, nurseries, museums, places of worship, and care homes. Factories, farms, building sites, mines, hospitals, and government premises fall under different enforcement bodies.
Pest control and sanitation: EHOs also investigate complaints about pest infestations and general sanitation in commercial premises like hotels and public swimming pools.
How EHOs Differ From Other Inspectors
People sometimes confuse EHOs with other regulatory bodies. In the UK, for example, the Health and Safety Executive (HSE) handles enforcement at factories, construction sites, farms, schools, hospitals, and government buildings. EHOs handle the rest, essentially any workplace where the public regularly visits as customers or guests. If you work in a restaurant and have a safety concern, you’d contact your local council’s environmental health department. If you work on a building site, you’d go to the HSE.
In the United States, the equivalent role often goes by the title Environmental Health Specialist or Registered Sanitarian, though the core functions are similar. These professionals work through state and local health departments rather than a single national body.
Qualifications and Training
Becoming an EHO requires specialized education. In the US, the typical pathway involves a bachelor’s or master’s degree in environmental health from a program accredited by the National Environmental Health Science and Protection Accreditation Council. Many roles also require certification as a Registered Environmental Health Specialist or Registered Sanitarian through the National Environmental Health Association. Some positions, particularly in federal service, require a master’s or doctoral degree in environmental health, occupational health, or industrial hygiene.
In the UK, EHOs typically need an accredited degree in environmental health followed by a period of supervised practice and registration with the Chartered Institute of Environmental Health. The training covers food science, housing law, toxicology, epidemiology, and occupational safety, reflecting the breadth of the role.
How to Contact an EHO
If you need to report a food hygiene concern, a housing hazard, or a noise complaint, your first step is contacting your local council or local health department. Most councils have an environmental health team you can reach by phone or through an online complaint form on the council’s website.
For food complaints specifically, the right contact depends on the type of product. Problems with a restaurant meal or food from a deli or grocery store typically go to your local health unit. Complaints about a manufactured or packaged product may need to go to a different branch, such as a food and drug unit, depending on where you live.
You don’t need evidence to make a complaint. EHOs are trained investigators, and a report from a member of the public is enough to trigger an inspection. If the EHO finds a genuine hazard, they have legal powers to require the business or landlord to fix the problem within set timeframes, or face penalties.
