What is L153?
L153 is the HSE's industry guidance document that accompanies L144, the Approved Code of Practice for the Construction (Design and Management) Regulations 2015. While L144 provides the ACOP and core legal guidance, L153 offers practical, sector-specific guidance on how to apply CDM requirements in real-world construction scenarios.
L153 covers the common construction hazards, provides examples of good practice, and explains how CDM duties translate into practical action on construction projects. It is designed to be used alongside L144, not as a replacement for it.
The guidance addresses the full range of construction activities, from groundworks and structural work through to mechanical and electrical installations, finishing trades, and demolition. It provides the detailed practical information that contractors, designers, and clients need to implement CDM effectively.
Who Needs This Document?
L153 is essential reading for:
- Principal contractors managing site health and safety
- Site managers and supervisors implementing safe working practices

- Clients understanding what good CDM practice looks like
- Project managers overseeing construction delivery
- Health and safety advisors advising on construction sites
- Trade contractors (groundworkers, steel erectors, roofers, etc.)

Welfare Facilities
L153 covers the welfare requirements in Schedule 2 of CDM 2015:
Sanitary Conveniences:
- Minimum numbers based on workforce size
- Cleaning and maintenance
- Lighting and ventilation
- Suitable for all workers (including disabled access)
Washing Facilities:
- Hot and cold running water
- Soap and towels or drying facilities
- Showers where required by the work
Drinking Water:
- Adequate supply of wholesome water
- Cups or drinking fountains
- Clearly marked as drinking water
Changing Rooms and Lockers:
- Secure storage for personal clothing
- Facilities for drying wet clothing
- Separate facilities where required
Rest Facilities:
- Shelter from weather
- Seating with backs
- Heating where necessary
- Facilities for preparing hot drinks and food
- Facilities for pregnant women and nursing mothers
Site Organisation and Control
L153 addresses how to organise and control construction sites effectively:
Site Security:
- Preventing unauthorised access
- Protecting the public
- Securing hazardous materials and equipment
Housekeeping:
- Maintaining clear access routes
- Removal of waste materials
- Storage of materials
- Lighting of working areas
Emergency Procedures:
- Fire prevention and protection
- First aid arrangements
- Rescue procedures
- Emergency routes and exits
Communication:
- Site inductions
- Toolbox talks
- Method statement briefings
- Reporting hazards and incidents
Coordination and Cooperation
L153 emphasises the importance of coordination between different parties:
Principal Contractor Duties:
- Organising cooperation between contractors
- Setting site rules
- Coordinating overlapping activities
- Managing shared risks
Contractor Cooperation:
- Following principal contractor directions
- Coordinating with other contractors
- Sharing information about hazards
- Participating in site meetings
Designer-Contractor Interface:
- Communicating design intent
- Highlighting residual risks
- Providing information for safe construction
- Feedback on buildability
Construction Phase Plan Development
L153 provides practical guidance on developing the construction phase plan:
Plan Contents:
- Project description and key dates
- Site rules and permitted working hours
- Management structure and responsibilities
- Arrangements for controlling significant site risks
- Welfare arrangements
- Emergency procedures
- Fire prevention arrangements
- First aid arrangements
- Health and safety monitoring arrangements
Proportionality:
- Simple plan for straightforward projects
- More detailed plan for complex or high-risk projects
- Focus on significant risks, not generic statements
Updating the Plan:
- Review as the project progresses
- Update for changes in work or circumstances
- Keep records of revisions
Specific Work Activities
L153 covers requirements for specific construction activities:
Steel Erection:
- Safe erection sequence
- Provision of safe access
- Prevention of falls
- Stability during erection
Concrete Work:
- Formwork and falsework
- Striking procedures
- Pre-stressed concrete
- Post-tensioning operations
Roofing Work:
- Edge protection
- Fragile surfaces
- Weather conditions
- Access to roof areas
Electrical Installation:
- Isolation procedures
- Testing arrangements
- Temporary electrical supplies
- Coordination with building services
Legal Status
L153 is guidance rather than an ACOP, so it does not have the same legal status as L144. However, it represents what HSE considers good practice for managing construction health and safety. Following L153 guidance alongside L144 will help demonstrate that suitable arrangements are in place to manage construction risks.
Inspectors will expect to see the types of arrangements described in L153 on construction sites. Failure to implement reasonable measures addressed in L153 may be cited as evidence of inadequate management arrangements.
Why It Matters
Construction remains a high-risk industry requiring robust health and safety management:
The Continuing Challenge
- Construction accounts for around 25% of workplace deaths each year
- Falls from height remain the most common cause of fatal injuries
- Being struck by moving vehicles is a major cause of death on sites
- Collapses and being struck by falling objects cause significant harm
- Musculoskeletal disorders affect many construction workers
- Occupational diseases including asbestos-related cancers continue to claim lives
Why L153 Helps
Practical Solutions:
- Concrete guidance on managing real construction risks
- Examples of what good practice looks like
- Proportionate approaches for different project scales
Common Standards:
- Industry-wide understanding of expectations
- Consistent approach across projects
- Benchmarks for competence and performance
Prevention Focus:
- Emphasis on planning to prevent incidents
- Hierarchy of control applied to construction hazards
- Coordination to manage interface risks
Consequences of Poor Practice
Human Cost:
- Fatal and life-changing injuries to workers
- Injuries to members of the public
- Long-term health damage from occupational disease
Legal Consequences:
- HSE enforcement including prohibition notices
- Criminal prosecution of companies and individuals
- Unlimited fines and potential imprisonment
- Corporate manslaughter charges for gross failures
Business Impact:
- Project delays from enforcement action
- Loss of reputation and future work
- Increased insurance premiums
- Civil claims from injured parties
Relationship with L144
L153 should be used alongside L144:
| Document | Focus | Status |
|---|---|---|
| L144 | Legal duties and ACOP provisions | Approved Code of Practice |
| L153 | Practical industry guidance | HSE Guidance |
L144 tells you what you must do; L153 helps you understand how to do it in practice.
