To ask the Secretary of State for Work and Pensions, how many mandatory investigations the Health and Safety Executive ended as a result of inadequate resources in each of the last five years.

Health and Safety Executive (HSE) selects cases for investigation on the basis of its published incident selection criteria (ISC) – incidents which notionally meet the criteria may not be selected for investigation or, where selected, investigations may conclude early for a number of reasons, including decisions around the most efficient deployment of resources. HSE does not hold specific figures relating to investigations falling within in its ISC which were concluded due to inadequate resources.
