The Work at Height Regulations 2005 is among the most important pieces of health and safety legislation affecting UK workplaces, placing legal duties on employers, the self-employed and anyone responsible for planning, supervising or overseeing work at height.
Employers and managers are required to reduce the risk of falls wherever reasonably practicable and ensure that anyone carrying out work where there is a risk of falling and being injured is properly protected. Importantly, there is no minimum height below which the regulations do not apply.
To help responsible parties understand what the Work at Height Regulations 2005 mean and what they cover, we've explained the main points of the legislation and how organisations can meet their legal obligations.
What are the Work at Height Regulations 2005?
The Work at Height Regulations 2005 were introduced to help reduce injuries and fatalities caused by falls from height in the workplace.
According to the HSE, a total of 126 workers were killed in work-related accidents during 2025/26 in the UK, with falls from height accounting for 25% of those fatalities, the highest proportion of any single cause of fatal workplace accidents.
The regulations apply across a wide range of industries where employees may be required to work at height, including construction, facilities management, utilities, telecommunications, warehousing, manufacturing and property maintenance.
Employers are required to ensure that work at height is:
- Properly planned & risk-assessed
- Appropriately supervised
- Carried out by competent workers
- Completed using suitable equipment
The objective is to prevent falls wherever possible, minimise the potential consequences where risks cannot be eliminated and reduce the severity of any remaining fall hazard.
Is There a Minimum Height for the Work at Height Regulations to Apply?
No. There is no minimum height specified in the Work at Height Regulations 2005. The regulations apply whenever there is a risk of someone falling a distance that could cause personal injury.
The commonly referenced "two-metre rule" is a rule from the long-repealed Construction (Health, Safety and Welfare) Regulations 1996, and has not been a threshold for determining whether the regulations apply for over two decades. Even work at relatively low heights and ground level still fall within the regulations if a fall could result in injury.
Who do the Work at Height Regulations apply to?
The regulations apply to employers and the self-employed, as well as anyone responsible for planning, organising or supervising work at height.
Employees and contractors also have responsibilities. They are expected to follow instructions, use equipment correctly and work in accordance with the safe systems put in place by their employer.
Employers, self-employed workers, construction companies, building management organisations, facilities management providers and anyone tasked with planning or overseeing work at height should therefore ensure they understand their responsibilities.
Businesses and management must:
- Avoid work at height where it isn't strictly necessary or where there is a safer alternative.
- Conduct suitable risk assessments that identify hazards, assess the likelihood of a fall or injury and determine appropriate control measures.
- Select equipment suitable for the task, from ladders and mobile elevating work platforms (MEWPs) to access towers, safety harnesses and edge protection systems.
- Ensure workers are competent, know how to use equipment safely and are provided with the appropriate information, instruction and training.
- Inspect and maintain equipment used for work at height, ensuring that ladders, MEWPs, scaffolding, harnesses and other safety equipment remain in good condition and are safe to use.
Does everyone Working at Height need a Licence or Qualification?
Not necessarily. Assessing competence doesn't simply mean checking whether an individual holds a licence, certificate or accreditation related to their work at height. Employers also need to consider whether workers have the appropriate knowledge, skills and experience to carry out the particular task safely.
Someone may hold a relevant qualification but still require additional instruction, experience or supervision depending on the equipment being used, the nature of the task and the working environment.
Competence should therefore be considered in the context of the work being undertaken rather than simply as a tick-box exercise.
Employer Responsibilities Under the Work at Height Regulations
The Work at Height Regulations place a number of responsibilities on employers and those planning or supervising work at height.
Planning Work at Height
Work at height must be properly planned before it begins. This includes considering whether the work can be avoided altogether and, if it cannot, determining how the risks can be prevented or minimised.
Good planning can identify potential problems before work begins and ensure that the appropriate equipment, people and procedures are in place.
Completing Risk Assessments
Risk assessments should identify the hazards associated with the work, consider who could be harmed and determine the measures required to control those risks.
This includes considering the likelihood of a fall, the potential consequences and whether the proposed equipment and working methods are appropriate.
Our risk assessment training can help those responsible for assessing workplace risks develop the knowledge required to undertake this process effectively.
Providing Appropriate Equipment
The equipment used should be suitable for the work being undertaken and the environment in which it will be used.
Depending on the circumstances, this could include ladders, stepladders, mobile access towers, scaffolding, MEWPs, guardrails, edge protection or personal fall protection equipment.
There is no single piece of equipment that is suitable for every work at height situation. The selection should be based on the task, the risks identified and the hierarchy of control.
Ensuring Workers Are Competent
Employers must ensure that anyone involved in work at height is competent or, where they are being trained, appropriately supervised by someone who is competent.
This is where suitable training plays an important role.
Is Working at Height Training a Legal Requirement?
In certain circumstances, yes.
The Work at Height Regulations do not specify that every worker must complete a particular course or qualification. Instead, they require employers to ensure that anyone involved in work at height is competent and has received appropriate training, instruction or supervision where necessary.
Recognised training is one of the main ways employers can develop and demonstrate competence while giving workers the knowledge and skills required to work safely.
The type of training required will depend on the work being undertaken. Someone using a mobile access tower, for example, will have different training requirements from someone operating a MEWP or using fall protection equipment.
Appropriate recognised work at height training can therefore form an important part of an organisation's overall approach to compliance.
Supervising Work
Work at height should be appropriately supervised, with the level of supervision depending on the complexity of the task, the risks involved and the experience and competence of those carrying out the work.
Effective supervision helps ensure that safe working procedures are followed and can identify when workers require further instruction, training or support.
Inspecting and Maintaining Equipment
Equipment used for work at height must be maintained in a safe condition and inspected where appropriate.
This can include ladders, access towers, scaffolding, MEWPs, harnesses, lanyards and other fall protection equipment.
Regular inspections can identify defects or deterioration before they contribute to an accident.
What Are the Ramifications of Non-Compliance With the Work at Height Regulations?
Failure to comply can have significant consequences. Depending on the circumstances, employers found to have breached the regulations could face:
- Health and Safety Executive enforcement action
- Improvement or prohibition notices
- Unlimited fines and criminal prosecution
- Increased insurance costs
- Reputational damage
- Civil claims following workplace accidents
Poor planning and non-compliance can also result in serious, avoidable injuries or, in the worst possible scenario, fatalities that could have been prevented.
Compliance should therefore not be viewed simply as a way of avoiding enforcement action. The purpose of the regulations is ultimately to prevent people from being injured or killed at work.
What Is the Most Important Requirement of the Work at Height Regulations?
There isn't one single requirement that can be considered in isolation. The regulations are based around a clear hierarchy of control.
Firstly, work at height should be avoided where it is reasonably practicable to do so. If work at height cannot be avoided, employers should take steps to prevent falls. Where a fall risk remains, measures should then be taken to minimise the distance and consequences of a potential fall.
This means that suitable equipment, competent workers, training, supervision, inspections and risk assessments all work together as part of an effective work at height safety system.
Steve Booker, Kentec Training's Managing Director, says:
"The Work at Height Regulations aren't only a case of meeting legal requirements, but about protecting people with the right training, planning and equipment to keep risks to a minimum.
Investing in safe working practices, training and good quality equipment is the best way to have the assurance that everyone working on any project at any height is expected to remain safe and well at the end of the day."
