Who does what under CDM?
The Construction (Design and Management) Regulations 2015 apply to every construction project in Great Britain, whatever its size. They set out clear roles, each with its own legal duties.
Client
Makes suitable arrangements for managing the project, appoints the principal designer and principal contractor where needed, and provides pre-construction information.
Principal Designer
Plans, manages and coordinates health & safety during the pre-construction phase, and prepares the health & safety file.
Principal Contractor
Plans, manages and coordinates health & safety during the construction phase, including the construction phase plan and site inductions.
Designers
Eliminate, reduce or control foreseeable risks through their designs, and provide information about the risks that remain.
Contractors
Plan, manage and monitor their own work, make sure workers are competent and trained, and cooperate with others on site.
Workers
Work safely, cooperate with others, and report anything they see that could endanger themselves or others.
The three key CDM documents
Pre-Construction Information
Information already held about the site and project — such as existing services, asbestos and site hazards — provided by the client to designers and contractors.
Construction Phase Plan
Sets out how health & safety will be managed during construction. Required for every project, and must be in place before the construction phase begins.
Health & Safety File
Information needed to carry out future work on the building safely, handed to the client at the end of projects involving more than one contractor.
Supporting your project at every stage.
Pre-Construction
We help you understand your duties, make the right appointments and gather the pre-construction information the project team will need.
Mobilisation
We make sure the construction phase plan, site set-up, welfare and inductions are all in place before work starts.
Construction
We manage or monitor the works on site — coordinating contractors, controlling high-risk activities and keeping the programme on track.
Monitoring & Reporting
Regular inspections, site meetings and progress reports keep you informed and make sure standards don't slip as the project moves on.
Handover
We pull together the health & safety file and handover information so the completed project can be used and maintained safely.
The legislation and guidance we work to.
We help make sure your site and your project meet the key requirements, including:
CDM Regulations 2015
The main regulations for managing health, safety and welfare on construction projects, including duties for every role and welfare requirements.
HSE L153
"Managing health and safety in construction" — the HSE's guidance on how to comply with CDM 2015.
Work at Height Regulations 2005
Planning, organising and carrying out work at height safely — one of the most common causes of serious injury on site.
BS 5975 — Temporary Works
The British Standard code of practice for temporary works procedures and the design, checking and use of falsework.
HSG144 — Vehicles on Construction Sites
HSE guidance on safe site layout, traffic routes and keeping people and vehicles apart.
Building Safety Act 2022
New Building Regulations dutyholder roles in England — separate from CDM roles — introduced from October 2023.
This is a summary for general information only. Requirements depend on the specifics of each project — we'll confirm exactly what applies to yours.

Common site management & CDM questions
Does CDM 2015 apply to my project?
CDM 2015 applies to all construction work in Great Britain — from small refurbishments to large new builds, and including domestic projects. The level of planning and documentation should be proportionate to the size and risk of the project, but the duties apply regardless.
Do I need to appoint a principal designer and principal contractor?
If more than one contractor will work on your project (or it's reasonably foreseeable that they will), the client must appoint a principal designer and a principal contractor in writing. If the client doesn't make these appointments, the client takes on those duties themselves.
What is a construction phase plan?
It's a document setting out how health & safety will be managed during the construction work, covering site rules, key risks and the controls in place. Every project needs one, and the client must make sure it's in place before the construction phase starts.
What goes in the health & safety file?
The health & safety file contains information needed to carry out future construction, maintenance, cleaning or demolition work safely — such as residual hazards, key structural details, services and materials used. It's required on projects with more than one contractor and is handed to the client at the end of the project.
Is the CDM principal designer the same as the Building Regulations principal designer?
No. Since October 2023, Building Regulations in England have their own dutyholder roles, including a principal designer and principal contractor focused on compliance with Building Regulations. These are separate from the CDM roles, which focus on health & safety — although the same organisation can hold both if it is competent to do so.
Can you represent us on site?
Yes. We can act as your client's representative — visiting site, monitoring progress, quality and safety, attending meetings and reporting back — so you have independent oversight without needing to be there yourself.
