Working at Height Regulations 2005: A Simple UK Guide

Falls from height are the single biggest cause of workplace death in Great Britain. Not machinery. Not vehicles. A fall.

That is exactly why the Work at Height Regulations 2005 exist. And here is the good news: once you strip away the legal wording, they come down to a handful of common-sense principles that any employer, manager or worker can follow.

In this guide I will walk you through what the regulations say, who they apply to, and what you actually have to do about it. Plain English. No jargon dumped on you without an explanation.

What are the Work at Height Regulations 2005?

The Work at Height Regulations 2005 (often shortened to WAHR 2005) are the main piece of UK law covering work carried out at height.

They came into force on 6 April 2005. Their single purpose is to prevent death and injury caused by a fall from height.

Before 2005, the rules were scattered across lots of older, industry-specific regulations. WAHR 2005 pulled them together into one consolidated framework that applies across pretty much every workplace.

Here is the thing most people get wrong straight away: these regulations are not just for scaffolders and window cleaners. They apply to a huge range of everyday tasks, from changing a light fitting on a stepladder to stacking a high warehouse shelf.

Who do the regulations apply to?

The regulations apply to all work at height where there is a risk of a fall liable to cause personal injury.

They place legal duties on three groups:

• Employers who ask staff to work at height.
• The self-employed working at height themselves.
• Anyone who controls the work of others at height. That includes facilities managers, building owners and contractors who arrange for other people to do the work.

If you are in that last group, this matters. You do not have to be the one holding the ladder to carry a legal duty. If you control the work, the responsibility follows the control (HSE).

Working out whether a specific task is high or low risk is the job of a proper risk assessment. If you are not sure where to start, our guide on working at height risk assessment breaks the process down step by step.

What actually counts as “work at height”?

This surprises people, so pay attention here.

There is no minimum height in the regulations. None.

A place is “at height” if a person could be injured by falling from it, even if that place is at or below ground level. So working next to an open excavation or a loading bay edge can count, even though you are not up a ladder.

“Work” also includes moving around a workplace at height, but not simply travelling to and from work. Everyday examples that fall under the regulations include:

• Using a stepladder or ladder.
• Cleaning gutters or windows above ground level.
• Working on a flat roof or a mezzanine.
• Loading or unloading from a raised platform.

The three key steps: avoid, prevent, minimise

This is the heart of the whole thing. If you remember nothing else, remember these three steps. They are the hierarchy the regulations are built around.

The overriding principle is simple, and HSE states it plainly:

“You must do all that is reasonably practicable to prevent anyone falling.”

Source: HSE, Work at Height Regulations: the law

To do that, you work through three steps in order:

1. Avoid. Avoid work at height where you can. Can the job be done from the ground instead? Use a long-reach tool, assemble something at ground level, or design the task so nobody has to go up at all.
2. Prevent. Where you cannot avoid working at height, use the right equipment and measures to prevent a fall. Think guard rails, working platforms and edge protection.
3. Minimise. Where you cannot fully remove the risk of a fall, minimise the distance and consequences of one. Think safety nets, airbags and, as a last line, personal fall-arrest systems like harnesses.

One golden rule sits inside step two and three: collective protection comes before personal protection.

In plain terms, a guard rail that protects everyone is better than a harness that protects one person, because a guard rail does not rely on someone remembering to clip on correctly. Choose collective measures first, and only fall back on personal equipment when you have to (HSE).

Employer duties versus worker duties

The regulations split responsibilities between the people in charge and the people doing the work. Let me break both down.

What employers must do

If you are an employer or you control work at height, you must make sure that:

• Work is properly planned, organised and supervised, including planning for emergencies and rescue.
• Everyone involved is competent for their role, or supervised by someone who is.
• The right equipment is selected, with collective protection prioritised over personal.
• Equipment is inspected and kept in safe condition.
• Weather conditions are taken into account, and work is postponed when the weather would make it dangerous.
• Risks from fragile surfaces and falling objects are properly controlled.

That is not a wish list. Each of those is a legal duty under the regulations (HSE).

What workers must do

Workers carry duties too. If you are working at height under someone else’s control, the regulations say you must:

• Report any safety hazard you spot to the person in charge.
• Use the equipment supplied properly, including any safety devices, and follow the training and instructions you have been given.
• Raise concerns before continuing if you genuinely believe something is unsafe, rather than pressing on regardless.

The bottom line? Safety at height is a shared job. Employers set it up correctly, and workers use it correctly.

The supporting duties you can’t ignore

Beyond the headline hierarchy, a few supporting duties trip businesses up more than any others. They are easy to forget, so here they are in one place.

Weather. You must postpone work at height when weather conditions would endanger health or safety. High winds and a working platform are a bad mix, and the law expects you to make that call.

Fragile surfaces. Nobody should go onto or near a fragile surface, such as a rooflight or an old asbestos-cement roof, unless it is the only reasonably practicable way to do the work safely. Where they must, you provide platforms, coverings and guard rails, and put up clear warning notices.

Falling objects. You must do all that is reasonably practicable to stop objects falling and injuring people below. Nothing should be thrown or tipped from height, and exclusion zones should be marked where there is a risk.

Inspection. Equipment must be inspected by a competent person after it is assembled or installed, and as often as needed to stay safe. For construction platforms where someone could fall more than 2 metres, an inspection must be recorded in writing (HSE).

Common myths about working at height

There is a lot of nonsense floating around about these regulations. Let me clear up the big ones.

Myth 1: There is a “two-metre rule”. There is not. The regulations do not set any minimum height. Whether a task is high or low risk depends on the job, where it is done, how it is done and what is going on around it, not a magic number.

Myth 2: Ladders are banned. They are not, and HSE has been saying so since 2005. Ladders and stepladders are a perfectly sensible choice for low-risk, short-duration tasks.

Myth 3: You can stay up a ladder as long as you like. As a rule of thumb, HSE treats “short duration” as no more than around 30 minutes on a ladder at a time. For longer jobs, a ladder should not automatically be your first choice (HSE).

Myth 4: This is only a construction problem. Falls happen in warehouses, shops, offices, farms and kitchens. If there is a fall risk, the regulations apply, whatever your industry.

Why competence sits at the heart of the regulations

Notice how often the word “competent” keeps coming up? That is no accident.

The regulations require that everyone involved in work at height is competent, meaning they have the right training, knowledge and experience for what they are doing. Anyone still learning must be supervised by a competent person.

Here is what most people miss: competence is not a nice-to-have. It is a legal requirement woven right through the regulations. You cannot plan, supervise or carry out work at height safely if the people doing it do not understand the risks.

That underpinning knowledge is exactly what good training gives your team. Our online Working at Heights course is a convenient, cost-effective way to build it, CPD-accredited, 100% online, and completed at your own pace with an instant digital certificate on passing.

Getting to grips with the Work at Height Regulations 2005 does not have to be daunting. Start with the three steps, be honest about the risks in your own workplace, and make sure the people going up are properly trained for it.
