Working at Height Regulations: A Practical Summary

Falls from height are still one of the biggest causes of serious injury and death in UK construction and the trades. If you climb a ladder, stand on a flat roof or work off a tower, the Working at Height Regulations apply to you. The trouble is most summaries are written by lawyers, for lawyers. Here is what the rules actually mean for a working tradesperson.

What "working at height" actually means

A lot of people assume "height" means scaffolding three storeys up. It does not. Under the regulations, you are working at height any time you could fall a distance that would cause injury. That includes:

• Standing on a step ladder to fit a light fitting
• Working off a tower or platform
• Working near a fragile roof light or an open edge
• Working at ground level next to an opening you could fall into (think a cellar hatch or a lift shaft)

There is no minimum height below which the rules switch off. A fall from a couple of rungs onto a hard floor can break a wrist or worse. Treat every off-the-ground task as work at height.

The duty: avoid, prevent, minimise

The regulations follow a simple hierarchy. You are expected to work down it in order, not just jump to whatever is easiest.

1. Avoid working at height where you reasonably can. Can the job be done from the ground? Extending poles, ground-level assembly and remote tools sometimes remove the need to climb at all.
2. Prevent falls where work at height is unavoidable. Use an existing safe place of work, or the right equipment — a tower, a MEWP (cherry picker), a properly secured ladder.
3. Minimise the distance and consequences of a fall where the risk cannot be fully removed — for example with nets, airbags or harness systems.

Quick tip: the law does not ban ladders. It says use the right equipment for the job. A short, low-risk task that takes a few minutes is exactly what a properly footed ladder is for. A full day of two-handed work is not.

Ladders, towers and MEWPs: choosing the right kit

Most disputes after an incident come down to one question — was the equipment suitable for that task? A rough guide:

• Ladders and step ladders — fine for short-duration, light work where you can maintain three points of contact. Inspect before use, set on firm level ground, and secure them.
• Mobile towers — better for longer tasks or where you need both hands and a stable platform. They must be erected by someone competent (PASMA training is the usual route) and checked before use.
• MEWPs — for higher or harder-to-reach work. Operators need the right IPAF category and a rescue plan in case someone becomes stranded.

Whatever you choose, it has to be inspected, maintained and used within its limits. Damaged or improvised access equipment is where a lot of accidents start.

Planning, competence and the weather

The regulations expect work at height to be properly planned, supervised and carried out by competent people. In practice that means:

• A sensible risk assessment before the job, written down for anything beyond the trivial. If you are unsure how risk assessments and method statements fit together, see our guide to RAMS explained.
• Checking the weather. High winds and ice turn a routine roof job into a serious one. Postponing is not weakness — it is competence.
• Making sure whoever does the work is trained for it. Competence is about the right knowledge and experience for that task, not a generic certificate.

If you employ people or use subcontractors, the duty to plan and supervise sits with you, not just the person on the ladder.

Fragile surfaces and falling objects

Two risks get overlooked again and again.

Fragile surfaces. Roof lights, old asbestos cement sheets, fibre-cement and rotten boarding can all give way without warning. Never assume a roof will take your weight. Use crawl boards, edge protection and clear signage, and treat any surface as fragile until proven otherwise. If asbestos might be involved, stop and check — our asbestos awareness guide covers what to do.

Falling objects. Working at height is not only about you falling. Tools, materials and debris falling onto people below cause serious injuries too. Keep work areas tidy, use toe boards and tool tethers, and cordon off the area beneath.

Keeping your paperwork straight

Equipment inspection records, risk assessments, method statements and training certificates all need to be findable — not buried in a van glovebox or a phone you have since dropped down a drain. If something goes wrong, or you face an audit, being able to produce the right document quickly matters.

This is where running your jobs through a single system helps. With a job-management platform like Gaffer you can attach risk assessments and inspection records to the job, store certificates against the customer and find them in seconds rather than digging through paperwork. Less admin, and you stay audit-ready. For more on that, see how to store certificates and stay audit-ready.

A note on the rules themselves: the Working at Height Regulations are updated and interpreted over time, and guidance from the HSE changes. Use this as a practical summary, not legal advice — always check the current official HSE guidance before relying on any specific point for a particular job.

FAQs

What is the minimum height for the Working at Height Regulations to apply?

There is no minimum height. The regulations apply to any work where a person could fall a distance liable to cause personal injury, even from a low step or near an opening at ground level.

Are ladders banned under the Working at Height Regulations?

No. Ladders are not banned. They are allowed for low-risk, short-duration tasks where a risk assessment shows it is reasonable. The rule is to use suitable equipment for the job, not to avoid ladders entirely.

Who is responsible for working at height safety on a job?

Duties fall on employers, the self-employed and anyone who controls work at height — including those who hire subcontractors. If you plan or supervise the work, the responsibility to do it safely sits with you, not only the person physically at height.

Do I need a harness to work at height?

Not always. A harness is one of the last lines of defence in the hierarchy. Where you can avoid the work, or prevent a fall with a tower, platform or edge protection, that comes first. A harness and the right anchor are used when the fall cannot otherwise be prevented.
