The Human Environment and Transport Inspectorate monitors and encourages compliance with both national and European legislation and regulations in favour of a safe and sustainable human environment, safe and sustainable transport and maintaining confidence in housing associations.

The activities of the inspectorate focus on good provision of services, fair enforcement and appropriate detection. If appropriate this is executed in collaboration with other inspectorates, is risk-driven, is based on mutual trust with the supervised organisation and moreover is focused on reducing the burden of supervision. Policy-makers determine the rules; people and businesses are responsible for compliance and the inspectorate monitors and enforces.

The environmental departments of the inspectorate are committed to the maintenance of a safe and healthy environment for people to live and work in and limiting harmful effects on the environment. For example they supervise the safety of building constructions and drinking water, the minimisation of the risks of hazardous substances and industries, the responsible processing of waste and the prevention and clean-up of contaminated soil and water.

The transport departments of the inspectorate are committed to the safety of  transport by road, on water and by air. Examples include the supervision of companies operating in these sectors, the rail and aviation infrastructure and the requirements with respect to rest and driving/sailing/flying times, professional competence, loading and maintenance.

The Housing Associations Authority (Aw) carries out the comprehensive risk-based supervision on housing, as stipulated in the Housing Act. It falls under the political responsibility of the Minister for Housing and Civil Service and has been incorporated in the Human Environment and Transport Inspectorate. The Aw monitors and protects the social resources of housing associations, so that they can be applied lawfully, effectively and efficiently in the interest of public housing.

The Human Environment and Transport Inspectorate was formed in 2012 following a merger of the Inspectorate for Housing, Spatial Planning and the Environment and  the Transport and Public Works Inspectorate.
