Working at Height in UK Construction

Working at height is one of the most dangerous activities on any UK construction site. According to HSE fatal injury statistics for 2025/26, falls from height accounted for 31 worker fatalities across all sectors, making it the single largest category of work-related death in Great Britain. In construction specifically, falls from height were responsible for over half of all worker fatalities. The Work at Height Regulations 2005 (SI 2005/735) exist to prevent these deaths and injuries.

This guide explains what counts as working at height, the legal framework, the hierarchy of risk control, equipment selection, and the responsibilities of employers, contractors and workers on UK construction sites.

What Counts as Working at Height?

The HSE defines work at height as any work in any place where, if no precautions were in place, a person could fall a distance liable to cause personal injury. This includes work above ground level, but also work at or below ground level where a person could fall from an edge into an excavation or a lower level.

Common examples on construction sites include:

• Working on scaffolds and tower scaffolds
• Working from ladders and stepladders
• Working on roofs and fragile surfaces
• Working near excavations and trenches
• Using mobile elevating work platforms (MEWPs) such as scissor lifts and boom lifts
• Working on formwork and falsework
• Climbing permanent or temporary stairways to access work areas

Walking up and down a permanent staircase in a building does not count as work at height, according to HSE guidance on common myths.

The Work at Height Regulations 2005

The Work at Height Regulations 2005 (WAHR) came into force on 6 April 2005. They apply to all work at height where there is a risk of a fall liable to cause personal injury. The regulations place duties on employers, the self-employed, and anyone who controls work at height (such as facilities managers or building owners who contract others to work at height).

The regulations contain 19 regulations and 8 schedules covering specific requirements for different types of work equipment. Key regulations include:

The Hierarchy of Risk Control

Regulation 6 of the Work at Height Regulations 2005 establishes a clear hierarchy of risk control that must be followed on every UK construction site. The HSE step-by-step guide sets out three levels:

Level 1: Avoid working at height

The first question must always be: can this work be done from the ground? If it is reasonably practicable to avoid working at height entirely, you must do so. Examples include using extendable tools from ground level, installing cables at ground level, lowering a lighting mast to ground level, and assembling edge protection at ground level before lifting it into position.

Level 2: Prevent falls using collective protection

If working at height cannot be avoided, you must prevent falls using either an existing place of work that is already safe, or the right type of work equipment. Collective protection measures do not require the individual worker to act for them to be effective. Examples include:

• Permanent or temporary guardrails
• Scissor lifts and mobile elevating work platforms (MEWPs)
• Tower scaffolds
• Scaffolding with guardrails and toe-boards

Level 3: Minimise the distance and consequences of a fall

If the risk of a fall cannot be eliminated, you must minimise the distance and consequences of any fall. Again, collective protection should be considered before personal protection:

• Collective protection: Safety nets, soft landing systems such as air bags, installed close to the level of work
• Personal protection: Industrial rope access, fall arrest systems using a high anchor point, work restraint systems

For each step in this hierarchy, HSE requires that collective protection is considered before personal protection. This is because collective measures protect everyone at risk without relying on individual behaviour.

Using Ladders and Stepladders

There is a persistent myth that HSE has banned the use of ladders on construction sites. This is not true. The HSE explicitly states that ladders and stepladders can be a sensible and practical option for work at height when:

• The use of other work equipment is not justified because of the low risk and short duration (short duration means working on a ladder for no more than 30 minutes at a time)
• There are existing workplace or site features which cannot be altered

However, ladders must be the right type (a suitable grade of industrial ladder), in good condition, and effectively secured (tied) to prevent movement. Ladders used for access must extend at least one metre above the landing point to allow for a secure handhold. Workers must be competent, which does not require formal qualification but does require the necessary skills, knowledge and experience.

Schedule 6 of the Work at Height Regulations 2005 sets out specific requirements for ladders, including that they must be positioned to ensure stability, prevented from slipping during use, and long enough to provide safe access.

Fragile Surfaces

Regulation 9 of the Work at Height Regulations 2005 places specific duties regarding fragile surfaces. Fragile surfaces include asbestos cement roofing sheets, glass panels including rooflights, wood wool slabs, and any other surface that would not support the weight of a person. Every employer must ensure that no person works on or near a fragile surface unless suitable and sufficient steps are taken to prevent falls through the surface.

Practical measures include:

• Covering the fragile surface with scaffolding or a platform
• Installing safety nets or air bags below the fragile surface
• Using fall arrest systems with adequate anchorage
• Displaying warning notices at every access point to the fragile area

HSE publishes specific guidance on fragile roofs in GEIS5 - Fragile roofs: Safe working practices.

Inspection Requirements

Regulation 12 of the Work at Height Regulations 2005 requires that work equipment used for work at height is inspected at suitable intervals and after any event that might affect its safety. Schedule 7 specifies the particulars that must be included in an inspection report:

• The name and address of the person for whom the inspection was carried out
• The location of the work equipment inspected
• A description of the equipment
• The date and time of the inspection
• Details of any matter identified that could give rise to a risk
• Details of any action taken as a result of the inspection
• Details of any further action considered necessary
• The name and position of the person making the report

Inspection reports must be kept until the next inspection is due, or for three months if the inspection was carried out less than three months before the equipment is no longer used.

Relationship with CDM 2015

The Construction (Design and Management) Regulations 2015 (CDM 2015) work alongside the Work at Height Regulations 2005. CDM 2015 places duties on clients, principal designers, principal contractors, designers and contractors to plan, manage and monitor health and safety throughout a construction project.

For work at height, CDM 2015 requires that designers eliminate, reduce or control foreseeable risks during the design phase. This means designing buildings that minimise the need for working at height during construction and maintenance. Principal contractors must ensure that work at height is included in the construction phase plan and that all contractors are competent.

HSE Enforcement and Penalties

HSE inspectors have the power to enter construction sites without a warrant, issue improvement notices requiring breaches to be remedied, issue prohibition notices stopping work immediately where there is a risk of serious personal injury, and bring criminal prosecutions. Breaches of the Work at Height Regulations 2005 can result in unlimited fines in the Crown Court and imprisonment for up to two years. In the Magistrates' Court, fines can reach £20,000 per offence.

According to HSE statistics for 2025/26, 25 construction workers were killed in work-related accidents, with falls from height accounting for the majority of these deaths. The construction industry remains the highest-risk sector for fatal injuries in Great Britain.

Common Work at Height Myths

HSE has published a list of common myths about working at height to help dispel misinformation:

• Myth: HSE has banned ladders on building sites. Fact: Ladders are permitted for low-risk, short-duration work (up to 30 minutes at a time).
• Myth: You need formal qualifications to use a ladder. Fact: You need to be competent, which can be achieved through on-the-job training and supervision.
• Myth: Walking up a staircase counts as working at height. Fact: Walking up and down a permanent staircase in a building is not work at height.
• Myth: You must always have two feet and one hand on a stepladder. Fact: You need three points of contact at the working position, which can include your body (knees or chest) supported by the stepladder.

Key Equipment for Working at Height

Worker Responsibilities

While the Work at Height Regulations 2005 place primary duties on employers and those in control of work, employees also have legal duties. Under the Management of Health and Safety at Work Regulations 1999 and the Health and Safety at Work etc. Act 1974, employees must:

• Take reasonable care of their own health and safety and that of others who may be affected by their actions
• Cooperate with their employer to enable health and safety duties to be complied with
• Use work equipment in accordance with training and instructions
• Report any dangerous situation or defect in work equipment to their employer

Regulation 14 of the Work at Height Regulations 2005 specifically requires that all persons at work must report any activity or defect relating to work at height which they know is likely to endanger the safety of themselves or others.
