Working at height is one of the most regulated activities in UK construction — and for good reason. Falls from height remain the leading cause of fatal injuries on construction sites, accounting for a significant proportion of workplace deaths recorded by the Health and Safety Executive (HSE) each year.
For construction managers, understanding the Working at Height Regulations 2005 is not just a compliance exercise. It is a fundamental part of your role. You are legally responsible for ensuring that work at height is planned, supervised and carried out by people who are trained and competent to do so.
This guide explains what the regulations require, how they apply to your responsibilities as a construction manager, what can happen when they are not followed, and how to ensure your team is properly trained and equipped.
What Are the Working at Height Regulations 2005?
The Work at Height Regulations 2005 came into force on 6 April 2005 and applies to all work in Great Britain where there is a risk of a fall liable to cause personal injury. The regulations place duties on employers, the self-employed, and any person who controls the way in which work at height is carried out. For construction managers, this means the regulations apply to you directly.
What Counts as Work at Height?
The regulations apply to any work where a person could fall from a distance that’s liable to cause personal injury. This is broader than many managers realise. It includes:
• Work on scaffolding, platforms and roofs
• Work on mobile elevating work platforms (MEWPs) and cherry pickers
• Use of mobile access towers
• Work on ladders and stepladders
• Work near edges, excavations or voids at ground level
• Work in fragile surface areas such as roof lights
There is no minimum height. If a fall could cause injury, the regulations apply.
The Hierarchy of Control: Plan, Avoid, Minimise
The regulations set out a clear hierarchy for managing work at height. Construction managers must apply this hierarchy in sequence — working through each level before moving to the next.
Priority
Requirement
Example
1 — Avoid
Avoid work at height entirely where reasonably practicable
Pre-fabricate components at ground level
2 — Prevent
Use work equipment or other measures to prevent falls where work at height cannot be avoided
Scaffolding, edge protection, MEWPs
3 — Minimise
Where the risk of falling cannot be eliminated, take steps to minimise the distance and consequence of any fall
Safety nets, harnesses, air bags
A common mistake is moving straight to personal protective equipment such as harnesses without first considering whether collective protection — such as scaffolding or guard rails — could eliminate the risk more effectively. The hierarchy requires collective measures to be considered before personal protection.
Your Legal Duties as a Construction Manager
1. Planning and Organisation
All work at height must be properly planned before it starts. This means:
• Identifying all tasks that involve working at height during the project
• Selecting the most appropriate access equipment for each task
• Ensuring method statements and risk assessments are in place before work begins
• Planning for emergencies and rescue procedures
2. Competency of Workers
The regulations require that all work at height is carried out by persons who are competent to do so, or if being trained, under the supervision of a competent person. As a construction manager, you are responsible for verifying competency before allowing workers to carry out tasks at height. Competency can be demonstrated through:
• Recognised qualifications such as IPAF, PASMA or CISRS
• Relevant experience supported by training records
• On-site assessment by a competent supervisor
3. Appropriate Equipment
Work equipment used for working at height must be suitable for the task and environment, stable and of sufficient strength. It must be inspected and maintained in accordance with manufacturer guidelines, and used only by trained and competent persons.
4. Inspection and Maintenance
Equipment used for working at height must be inspected before use, after assembly on a new site or location, after any event that could affect its stability or safety, and at regular intervals appropriate to the type of equipment and conditions of use. Inspection records must be kept and made available on request.
Common Compliance Failures and How to Avoid Them
The HSE regularly identifies specific failures when investigating falls from height on construction sites. Understanding these common failings helps managers put the right controls in place.
Common Failure
Why It Happens
How to Prevent It
No risk assessment for the task
Assumed the work was routine or low risk
Require written risk assessments for all work at height regardless of perceived risk
Incorrect equipment for the task
Equipment chosen on availability rather than suitability
Specify equipment in method statements before work begins
Unqualified workers operating equipment
Assumed experience was sufficient or certification not checked
Verify certification for all operators before allowing access
Damaged or uninspected equipment
Inspection records not maintained or equipment not checked before use
Implement daily pre-use inspection records for all access equipment
No emergency plan
Rescue plan not considered or not communicated to workers
Include rescue procedures in all method statements for work at height
Consequences of Non-Compliance
HSE Enforcement Action
The HSE has powers to issue Improvement Notices, Prohibition Notices and Prosecution. Where serious breaches are identified, work can be stopped immediately. Prosecutions under the Health and Safety at Work Act can result in unlimited fines for employers.
Personal Liability
Individual managers can be prosecuted where the breach was attributable to their act or omission. Directors and senior managers can face personal fines or, in cases of gross negligence, imprisonment under the Corporate Manslaughter and Corporate Homicide Act 2007.
Civil Claims
Workers injured in a fall from height may bring civil claims against their employer. Where training records are incomplete or method statements are absent, employers face significantly increased liability.
Training Requirements for Construction Managers
The regulations require competency, not just attendance on a training course. As a construction manager, you need to understand the specific training requirements for each type of equipment and task your team carries out.
Activity
Required Training
Card / Certification
Operating a cherry picker or MEWP
IPAF (relevant category)
PAL Card — valid 5 years
Assembling or working on a mobile tower
PASMA
PASMA Card — valid 5 years
Erecting and dismantling scaffolding
CISRS (Construction Industry Scaffolders Record Scheme)
CISRS Card
Harness use and fall arrest
Fall protection and harness inspection training
Evidence of training / competency record
Site management responsibility
SMSTS (Site Management Safety Training Scheme)
SMSTS Card — valid 5 years
For construction managers, SMSTS is the foundation qualification that gives you the knowledge to manage health and safety responsibilities on site — including your obligations under the Working at Height Regulations.
Pre-Work Checklist: What to Check Before Work at Height Begins
Use the following checklist before authorising any work at height on your site:
• Has a written risk assessment been completed for this specific task?
• Is a method statement in place that specifies the equipment to be used?
• Is the selected equipment suitable and appropriate for the task and environment?
• Have all workers been checked for relevant certification (IPAF, PASMA, CISRS as applicable)?
• Has the equipment been inspected and is it in safe working order?
• Are inspection records available and up to date?
• Is an emergency and rescue plan in place and communicated to the team?
• Have workers been briefed on the specific hazards for this task at this location?
Frequently Asked Questions
Is there a minimum height that triggers the regulations?
No. The Work at Height Regulations 2005 apply wherever there is a risk of a fall liable to cause personal injury, regardless of the height involved.
Are ladders still permitted under the regulations?
Yes, ladders can still be used where the risk assessment shows their use is justified. However, they should only be used for short-duration work of low risk, and the regulations require that alternative equipment is considered first.
Who is responsible if an unqualified worker is injured in a fall?
Responsibility can fall on the employer, the principal contractor and the individual manager who authorised or was aware of the work. All parties who failed to ensure competency can face enforcement action and civil claims.
How often do risk assessments need to be reviewed?
Risk assessments must be reviewed whenever there is a reason to believe they are no longer valid. For example, when conditions change, after an incidentor when new equipment or working methods are introduced.
Do the regulations apply to visitors on site?
The regulations apply to all persons on site, including visitors. As a construction manager, you are responsible for ensuring that visitors are not exposed to risks from work at height.
Conclusion
The Working at Height Regulations 2005 place clear and enforceable duties on construction managers. Understanding and applying them is not simply a legal obligation — it is the foundation of responsible site management.
As a manager, your responsibilities include planning all work at height before it begins, applying the hierarchy of control, ensuring all workers are competent and certified, maintaining inspection records, and having a rescue plan in place before work starts.
Holding the right qualifications — SMSTS for site management, combined with IPAF, PASMA or CISRS as relevant to your site — ensures you are equipped to meet these responsibilities and protect your team.
