What Is Working at Height?
What Is Working at Height?
Working at height is any task where someone could fall far enough to injure themselves. It covers more than just roofs or scaffolding. Jobs done on ladders, near open edges, or even in raised storage areas can all count. If there’s a risk of falling, it’s classed as working at height.
That’s why understanding what is working at height is so important for staying safe. These types of tasks remain one of the most common causes of serious injury at work in the UK. That’s why safety can’t be left to chance. Even low-level tasks carry risk if the right steps aren’t taken.
To reduce accidents, the Work at Height Regulations 2005 were introduced. They outline what’s expected from employers and anyone in charge of planning or supervising this kind of work. It’s essential to know at what height you are considered to be working at height. The rest of this guide breaks down what that involves and how to stay safe on the job.

How is working at height defined?
Working at height means doing any job where you could fall and injure yourself. It doesn’t have to involve scaffolding or tall buildings. If there’s a risk of falling, it counts.
Working at height is defined by the Health and Safety Executive (HSE) as any place where a fall could cause injury. That includes working above ground level, next to an open edge, or near a hole in the floor.
This applies across a wide range of jobs. Think of tradespeople fixing roof panels, warehouse staff unloading stock from high platforms, or maintenance teams repairing lighting in raised plant rooms. If the task puts someone at risk of falling, it’s working at height.
The height itself isn’t always the issue. What matters is the potential for harm. Even a fall from under two metres can lead to serious injury if the conditions aren’t safe.
In 2022/23, there were 40 fatal accidents involving falls from height, according to the HSE. Many of those incidents happened during routine jobs that didn’t seem dangerous. That’s why it’s so important to know when a task falls into this category and plan it properly.
What is classed as working at height?
Knowing what is classed as working at height helps identify risks on any site. Jobs are classed as working at height when there’s a risk of falling that could cause injury. This includes tasks done above ground level, as well as work near an edge or opening where someone could fall through or off.
Common examples include working on roofs, using ladders, or installing equipment on scaffolding. It also covers tasks carried out on raised platforms, cherry pickers, or mobile tower systems.
The exact setup often depends on the job. On a construction site, working at height might involve steel framework or scaffolds. In a warehouse, it might be someone loading stock from high shelving or checking lighting from a stepladder. In both cases, the key consideration is whether a fall could happen and cause harm.
If there's a chance someone could fall, the task is classed as working at height, no matter the location or industry.
At what height are you considered to be working at height?
There isn’t a fixed height that automatically qualifies a task as working at height under UK law. The Health and Safety Executive (HSE) focuses on the risk of falling, not just how far.
Understanding at what height you are considered to be working at height helps employers decide when formal fall protection and planning are required. That said, many businesses and industries use 2 metres as a practical benchmark. Knowing at what height you are considered to be working at height means tasks above this height usually require full fall protection measures. But even tasks below two metres might still count as what is classed as working at height if there’s danger. This includes but isn’t limited to working on a low roof, step ladder, or raised platform where there’s a chance of injury from a fall.
It all depends on the situation. If someone could fall through a fragile surface, over a guardrail, or down a stairwell, it doesn’t matter if the height is 1.8 or 1.2 metres. It’s still a risk. That’s why a proper risk assessment is always needed before starting the job, whatever the height.
Key requirements for working at height
Working at height must always be properly planned, using the right people and equipment. Before any task begins, carry out a proper risk assessment informed by HSE guidelines and put clear safety controls in place.
Training and certification
Everyone involved should be trained to recognise hazards, use equipment correctly, and know how to respond in an emergency. For many jobs, formal certification is needed to operate platforms, scaffolds, or fall protection systems.
Equipment checks
Ladders, platforms, and harnesses must be inspected before each use. Damaged or unsuitable gear should be removed from service immediately. This falls under both the Work at Height Regulations and PUWER.
The competent person
Every job involving height must be overseen by someone classed as ‘competent’. That means they need enough training, knowledge, and experience to plan the work safely and supervise it throughout.
Shared responsibility
Employers must provide safe systems and the right equipment. Workers must follow procedures, use the kit properly, and report any risks they spot. Keeping everyone safe is a team effort.
Important safety considerations for working at height
Working at height always carries risk, which is why safety must be considered before any job starts. A full risk assessment should identify hazards such as fragile surfaces, poor weather, unprotected edges, or unsuitable access.
Once you’ve identified the risks, you must apply the correct control measures. This might involve using guardrails, fall arrest systems, or PPE such as harnesses and helmets. Supervision, proper training, and safe equipment are essential throughout the job.
Every decision should focus on preventing a fall, not just reducing the impact. Below, we’ll explain how to assess and control such risks effectively.
Assessing and controlling risks
Understanding what is working at height for each specific situation means risk assessments are never one-size-fits-all. You need to think about where the job’s being done, what equipment is involved, and what might cause a fall.
Environmental factors such as strong winds, rain, or icy ground can all raise the risk. Uneven or fragile surfaces should also be picked up early. These conditions affect how stable your equipment will be.
Once the risks are clear, choose the safest way to get the job done. Avoid working at height if you can, and always plan to prevent a fall.
Collective and personal protection
Choosing the right safety measures for working at height depends on the job, but protection should always come first. Start with collective protection (measures that protect everyone), then add personal protection where needed.
Collective protection includes:
-
Guardrails and barriers to prevent falls
-
Proper scaffolding or fixed access platforms
-
Clear safety signs to mark hazards
Personal protection includes:
-
Harnesses and tool lanyards to prevent injury from falls or dropped tools
-
Hi vis workwear to stay visible on site
-
Helmets and accessories to reduce the risk of head injuries or slips
Always check that the equipment is in good condition. Don’t use ladders or platforms that are damaged or unstable. Training, regular breaks, and proper planning help reduce fatigue and lower the chance of mistakes.
Understanding ‘The Work at Height Regulations (2005)’ in the UK
The Work at Height Regulations 2005 were created to reduce deaths and serious injuries caused by falls. The rules apply to anyone organising or overseeing jobs that fall under what is working at height. This includes employers, site managers, contractors, and building owners.
These regulations clarify how working at height is defined and what duty holders must do to manage it. All work must be properly planned, supervised, and carried out by workers who are trained and competent. Before any job begins, duty holders must complete a risk assessment, decide if the task can be done safely from the ground, and choose the most suitable access method if it can’t.
They are also responsible for providing safety measures that match the job. This includes equipment like guardrails, harnesses, helmets, and safety signage. All gear must be inspected, training should be kept up to date, and supervision must be in place.
These duties apply across all types of work. Whether the task is a quick fix or part of regular operations, the same rules exist to protect everyone involved.
Key responsibilities for duty holders under the work at height regulations
Anyone responsible for people working at height, including employers, building owners, and contractors, has legal duties under the Work at Height Regulations 2005. They must first understand how working at height is defined to make sure they’re meeting legal duties and planning work correctly. Their responsibilities apply to every job where there’s a risk of falling.
Duty holders must make sure that all work is properly planned and carried out by competent workers with the right training. A full risk assessment must be completed before any task begins, considering the location, access, equipment, and potential hazards.
Employers are also responsible for providing the correct personal protective equipment (PPE), such as harnesses, helmets, and non-slip footwear. That kit must be suitable for the job and in safe working condition.
Training should be refreshed regularly, including clarity on at what height you are considered to be working at height, especially when equipment changes or new risks arise. The goal is always the same: to prevent falls and keep everyone on site safe.
Key takeaways for working at height
Working at height carries serious risks. Falls remain one of the leading causes of workplace injuries in the UK, and most incidents happen when planning, supervision, or equipment checks are overlooked.
Before every job, ask yourself: What is classed as working at height in this situation? Then begin every task with a full risk assessment. Employers must check that equipment is fit for purpose, that all protective measures are in place, and that only competent workers are involved. Where possible, use collective protection like guardrails before turning to personal safety gear such as helmets or harnesses.
Regulations also require clear supervision and training. If a worker isn’t properly trained or if conditions are unsafe, the job shouldn’t go ahead.
Overall, knowing what is working at height and following safety and workwear guides can help reduce the risk of falls and keep everyone safe on site.
