Working at Height Regulations: A Guide for Construction Sites in the UK

Working at height remains one of the most common causes of serious and fatal injuries on construction sites. Falls from ladders, scaffolding, roofs and other elevated structures account for a significant portion of workplace accidents, yet many of these incidents are preventable with proper planning, equipment and training.

In the UK, employers and those in control of work at height activities must comply with the Work at Height Regulations 2005, a legal framework designed to protect workers from falls and ensure safe access for construction tasks.

What Counts as Working at Height?

Under UK law, “working at height” means any activity where a person could fall a distance liable to cause personal injury. This includes:

  • Working on scaffolding or elevated platforms

  • Tasks above floor level where a fall could occur

  • Access or egress from raised structures

  • Work near fragile surfaces (e.g. rooflights) that could give way

Even relatively low heights can present significant risk, as a fall from just a few metres can result in serious injury.

Who Must Comply With the Regulations?

The Work at Height Regulations apply to:

  • Employers

  • The self-employed

  • Those who control the work of others (e.g. facilities managers, principal contractors)

These duty holders must ensure work at height activities are properly planned, supervised and carried out by competent people, and that the risks are identified and appropriately controlled.

Core Requirements of the Regulations

The Regulations are built around a hierarchy of controls designed to prevent accidents rather than simply respond to them:

1. Avoid Work at Height Where Possible

If a task can be done safely from ground level using extending tools or other methods, this should be the first choice.

2. Assess Risks and Plan Work

A thorough risk assessment must identify hazards and determine the safest approach. This includes considering weather conditions, access points, and how workers will reach and leave the work area.

3. Use Suitable Equipment

Where work at height cannot be avoided, employers must provide appropriate work equipment and ensure it is used safely. Equipment includes scaffolding, mobile towers, ladders (where appropriate), access platforms and personal safety gear.

4. Competence and Training

Those carrying out work at height must be trained and competent. This can involve formal qualifications or training (such as Ladder Association or PASMA training) or job-specific instruction.

5. Inspection and Maintenance

Equipment used at height must be regularly inspected and maintained. For scaffolding and platforms where a person could fall two metres or more, inspections should take place at hand-over and at least weekly thereafter.

When Can Ladders Be Used?

Contrary to some belief, ladders are not banned in the UK, but the Regulations make clear that they are suitable only when:

  • The task is short duration

  • A risk assessment shows more suitable equipment (e.g. scaffolds) is impractical

  • Workers can maintain three points of contact while climbing and working safely

Where ladders are used, they must be secure and inspected, and should extend at least 1 metre above the platform to allow a secure handhold.

Beyond Equipment: Culture and Competence

Selecting the right access solution is only part of the equation. Employers must also ensure:

  • Workers understand site hazards and safety expectations

  • Plans are in place for emergencies and rescue from height

  • Supervisors monitor compliance and intervene when unsafe behaviour occurs

Regular training, clear communication and a culture that prioritises safety at every level are essential in reducing falls and serious injuries.

Why This Matters for Construction

Falls from height are consistently among the leading causes of fatalities and major injuries in UK construction. Proper adherence to the regulations, combined with effective planning and equipment selection, helps protect workers and ensures compliance with legal duties.

Using compliant, well-maintained access equipment, like scaffolding systems, ladders fitted with guards, secure staging boards and appropriate extension ladders, supports safer outcomes and reduces risk exposure across projects.

Key Takeaways

✔ Work at height includes any risk of falling a distance with injury potential.
✔ The Work at Height Regulations 2005 set out duties for planning, risk assessment, suitable equipment, and inspection.
✔ Avoid working at height where possible, otherwise control and minimise risk.
✔ Ladders have specific permitted uses and must be secure and inspected.
✔ Training and competence are essential for any work at height activity.
