Working at Height UK: Safety Rules & Risk Guide

Overview

Working at height is any task carried out in a place where, without precautions, a person could fall a distance likely to cause injury. That definition is deliberately broad. It covers the obvious cases like scaffolds, cherry pickers, and roof work, but it also covers loading bays, open manholes, fragile surfaces such as skylights, and even low level work where someone could fall into an excavation.

In England, Scotland and Wales the primary framework is the Work at Height Regulations 2005, which sits alongside the Health and Safety at Work etc Act 1974 and the Management of Health and Safety at Work Regulations 1999. The duties apply to employers, the self-employed, and anyone who controls how work at height is carried out.

The approach set out in the Regulations follows a hierarchy: avoid the work where possible, then prevent falls, and finally minimise the consequences if a fall does happen. Understanding that hierarchy is the foundation of everything else.

Key steps

1. Decide whether the work at height is necessary at all. The first question under the hierarchy is whether the task can be done without working at height in the first place. Assembling on the ground, using extending tools, or redesigning the process can remove the risk entirely. If you can eliminate the hazard, you should.
2. Carry out a proper risk assessment before work begins. Look at the height involved, the duration of the task, the surface conditions, weather exposure, the weight being handled, and the experience of the people doing the job. Write it down, share it with the team, and review it if anything on site changes. A generic assessment copied from a previous job rarely covers the real risks.
3. Select equipment that matches the task and the environment. A stepladder suits short, light duty tasks with three points of contact. Scaffolds, mobile towers, and mobile elevating work platforms suit longer jobs or heavier loads. Choose collective protection such as guard rails over personal protection such as harnesses wherever you can, because collective measures protect everyone at once.
4. Train, brief, and supervise the people doing the work. Competence means more than a certificate on the wall. Workers need to understand the specific equipment, the site conditions, and the emergency procedures for that job. Supervision should be active, not a signature on a form. Anyone erecting scaffolds or operating powered access equipment should hold the appropriate qualification for that kit.
5. Inspect, maintain, and record checks on all access equipment. Ladders, harnesses, anchor points, scaffolds, and powered platforms must be checked before use and at the intervals set by the manufacturer or the Regulations. Damaged equipment should be taken out of service immediately, not patched up. Keep written records of inspections so you can show what was checked and when.
