Overview
Meet your responsibilities with confidence
Construction and refurbishment projects carry legal responsibilities that many property owners, landlords and developers are unaware of until a project is already underway.
The Construction (Design and Management) Regulations 2015 (CDM Regulations) apply to most construction projects in the UK and place duties on clients, designers and contractors to ensure health and safety is properly managed throughout the project lifecycle.
At Ashstep Surveys, we provide practical CDM advice and consultancy services to help commercial property owners, landlords, developers and businesses understand their obligations, reduce risk and ensure projects remain compliant.
Whether you are planning a refurbishment, extension, redevelopment project or major maintenance works, we can help you navigate your responsibilities with confidence.
Planning Construction or Refurbishment Works?
Speak to Ashstep Surveys before your project begins to ensure your legal obligations are understood and properly managed.
Why it matters
CDM duties are not optional
Historically, companies found in breach of CDM Regulations have faced fines averaging over £71,000 — escalating to hundreds of thousands, or even millions, for major safety failures.
Clients cannot simply delegate these responsibilities to contractors. Getting the right advice early is the most effective way to manage the risk.
What it is
What Are CDM Regulations?
The Construction (Design and Management) Regulations 2015 are the primary health and safety regulations governing construction projects in the UK.
Their purpose is to improve health, safety and welfare throughout construction projects by ensuring risks are properly identified, managed and communicated. The regulations apply to a wide range of projects, including:
Many clients are surprised to learn that CDM duties apply to projects of all sizes, not just large developments.
Does it apply?
Do CDM Regulations Apply to My Project?
In most cases, the answer is yes. CDM Regulations apply to virtually all construction work, including:
Refurbishment Projects
Internal and external alterations to existing buildings.
Building Extensions
Commercial and mixed-use extensions.
Roof Replacement Works
Repairs, maintenance and replacement projects.
Structural Alterations
Works affecting walls, floors, roofs and structural elements.
Planned Maintenance Projects
Major maintenance and improvement works.
Property Conversions
Change of use and redevelopment projects.
If you are unsure whether CDM Regulations apply, we can provide advice at an early stage.
The client role
What Is a Client Under CDM?
Under CDM Regulations, the "Client" is the individual or organisation commissioning the construction work. This could include:
Importantly, clients have legal responsibilities under CDM and cannot simply delegate all responsibility to contractors. Understanding these duties is critical to ensuring compliance.
Your duties
Client Duties Under CDM Regulations
Clients must make suitable arrangements for managing health and safety throughout the project. This includes:
Appointing Competent Duty Holders
Ensuring designers and contractors have the necessary skills, knowledge and experience.
Providing Pre-Construction Information
Making relevant building and site information available to the project team.
Allowing Adequate Time and Resources
Ensuring projects are properly planned and managed.
Ensuring Effective Coordination
Facilitating communication between designers and contractors.
Monitoring Arrangements
Taking reasonable steps to ensure health and safety responsibilities are being fulfilled.
Failure to comply can expose clients to legal, financial and reputational risks.

The value
Why CDM Compliance Matters
Good CDM management is not simply about legal compliance. It can also help:
- Improve project safety
- Reduce the risk of accidents, incidents and claims against you
- Avoid project delays
- Improve communication between project teams
- Support better project planning
- Reduce unforeseen costs
- Protect property owners and businesses
Early consideration of CDM responsibilities often leads to smoother project delivery and better outcomes.
In practice
CDM and Commercial Property Projects
Many of the projects we support involve existing commercial buildings where clients may not realise that CDM obligations apply. Even relatively straightforward projects can trigger client duties under CDM Regulations.
Set your project up correctly from the outset
Obtaining advice at an early stage can help ensure the project is set up correctly, avoiding costly changes once works are underway.
Principal Designer
Principal Designer Support
Where a project involves more than one contractor, the appointment of a Principal Designer may be required under CDM Regulations.
The Principal Designer has responsibility for planning, managing and monitoring health and safety during the pre-construction phase. Ashstep Surveys can assist clients by:
- Explaining Principal Designer requirements
- Helping identify appropriate appointments
- Reviewing project responsibilities
- Supporting compliance throughout the project lifecycle
Our experience managing construction projects ranging from individual refurbishments through to multi-million-pound schemes allows us to provide practical advice tailored to each project.
