Working at Height: The Law and Staying Safe in the UK

Workplace Safety Guide

From a stepladder indoors to a scaffold several storeys up, working at height carries a risk that's easy to underestimate. This guide covers the legal hierarchy you must work through, where falls actually happen, and how to choose equipment that keeps people safe.

Why the HSE prioritises it

Falls from height are consistently the single biggest cause of workplace fatalities in the UK, and many serious injuries come from low falls — ladders, platforms and fragile roofs.

The common thread: the outcome is set by decisions taken before the work begins.

Falls are a leading cause of workplace deaths

Ladders

Quick jobs, big risk

Most fall incidents involve ladders. Use them only for low-risk, short-duration work, footed and secured.

The hierarchy: avoid, prevent, minimise

The law requires you to work through three levels in order — don't reach for a harness when you could have stayed on the ground.

Avoid

First choice

Do the work from the ground if you possibly can — the only fall you can't have is the one you avoid.

Prevent

If you must go up

Use a safe platform, guardrails or a secured ladder so a fall can't happen in the first place.

Minimise

Last resort

Where a fall risk remains, cut the distance and consequences with nets, airbags or fall-arrest.

💡 The rule that saves lives

If you can do the job from the ground, do it from the ground. The safest height is no height.

Controlling it on site

When height is unavoidable, four steps keep it under control:

Plan and assess

Risk-assess the task, the height and the conditions. Can it be done from the ground instead?

Pick the right equipment

Match the kit to the job — tower, MEWP, podium or a secured ladder for short, light work.

Inspect before use

Check ladders, platforms and harnesses every time. Damaged equipment is taken out of use.

Supervise and react to weather

Competent supervision throughout, and stop work in high wind, rain or ice.

What the law requires

Under the Work at Height Regulations 2005 (enforced by the HSE), all work at height must be planned, supervised and carried out by competent people. The duties follow a clear hierarchy:

Avoid work at height where it's reasonably practicable
Use the right equipment and competent people
Inspect access equipment before use
Plan for emergencies and rescue

Working at height questions

Is there a height at which the rules start? +

No — the Work at Height Regulations 2005 apply to any work where a person could fall a distance liable to cause injury.

Do I always need a harness? +

No — fall arrest is a last resort. Preventing the fall with a platform or guardrails is preferred.

How often is training refreshed? +

Typically every 2–3 years, or sooner if equipment or duties change.

Is the certificate recognised? +

Yes — CPD-aligned and accepted by employers across the UK.

Falls from height: still the UK's biggest cause of workplace deaths
