The bigger picture
What are statutory inspection regulations?
All four regimes flow from one parent law, the Health and Safety at Work etc. Act 1974, and all four are enforced by the Health and Safety Executive. Each one targets a different hazard, but they share a common spine: dangerous equipment must be examined by a competent person, on a defined schedule, with a written record you can produce on request.
They are not advisory. A breach is a criminal matter, and the duty sits with the employer, owner or person in control of the equipment, even when it is hired in rather than owned. The penalties scale with harm and turnover, but the costs that hurt most are the unbudgeted ones: a stopped site, an invalidated insurance policy, and the human cost of a preventable injury.
The hard part is rarely the inspection itself. It is knowing which regulation applies to which piece of kit, and keeping every due date in view across a busy site. That is what this page, and the four guides it links to, are here to make simple.
