A Network Rail Principal Contractor Licence (PCL) allows an organisation to act as Principal Contractor on Network Rail managed infrastructure for HSE F10-notifiable projects. JVR Consultancy helps organisations prepare for PCL assessment by strengthening management systems, operational controls and evidence to meet Network Rail requirements.
Achieve Principal Contractor Licence (PCL) Accreditation with JVR Consultancy
JVR Consultancy supports organisations preparing for and maintaining a Network Rail Principal Contractor Licence (PCL). We help businesses strengthen their management systems, prepare for assessment and align their operational controls with the expectations required to work directly for Network Rail as a principal contractor.
A Principal Contractor Licence is not simply another supplier accreditation. It represents a significantly higher level of operational responsibility within the rail industry and is typically held by organisations managing projects directly on behalf of Network Rail.
For many businesses, the challenge is not simply understanding the requirements, but understanding the level of control, coordination and accountability expected once a licence is achieved.
What a Principal Contractor Licence is
A Principal Contractor Licence (PCL) is an approval process used by Network Rail for organisations taking direct responsibility for delivering rail projects.
Network Rail actually distinguishes between two related instruments. A Principal Contractor Certificate (PCC) applies where more than one contractor is working on a project, or it’s reasonably foreseeable that more than one contractor will be involved at any time. A Principal Contractor Licence (PCL) applies at a higher threshold — specifically, where the project is HSE F10-notifiable, meaning it runs for more than 30 working days with more than 20 workers working simultaneously at any point, or exceeds 500 person-days. This page covers PCL specifically, for organisations operating above that threshold.
The PCL exists specifically to ensure organisations can discharge their duties as Principal Contractor under the Construction (Design and Management) Regulations 2015 (CDM 2015) on Network Rail managed infrastructure. It is a legal requirement for any organisation wishing to take on that role where Network Rail is the client.
Unlike RISQS, which is primarily a supplier assurance scheme used across the rail supply chain, a PCL applies to organisations managing entire projects directly for Network Rail.
This includes responsibility for:
- Site safety and coordination
- Subcontractor management
- Welfare arrangements
- Inductions and briefings
- Safe systems of work
- Protection from train movement
- Regulatory and operational compliance
In practice, PCL holders are responsible for controlling how work is delivered safely within a live rail environment.
How PCL differs from RISQS
RISQS and PCL are often discussed together, but they serve very different purposes.
It’s also worth distinguishing PCL from the Principal Contractor Certificate (PCC), which applies to smaller projects below the HSE F10 notification threshold — see “What a Principal Contractor Licence is” above.
RISQS allows organisations to become visible within the rail supply chain and demonstrate supplier assurance requirements.
A Principal Contractor Licence sits at a higher level. It applies to organisations managing work directly for Network Rail and taking responsibility for the delivery and control of entire projects.
For example:
- A RISQS-accredited subcontractor may deliver one element of a project
- A PCL holder manages the overall site, coordination and operational control of that project
This distinction is important because the level of scrutiny, responsibility and competence expected under PCL is significantly higher.
| RISQS | PCC | PCL | |
|---|---|---|---|
| What is it? | Rail supplier assurance and qualification | Principal Contractor Certificate | Principal Contractor Licence |
| Main purpose | Demonstrating supplier capability and assurance | Approval to act as Principal Contractor below the F10 threshold | Approval to act as Principal Contractor on F10-notifiable projects |
| When does it apply? | Depends on the supplier's activities and buyer requirements | Where more than one contractor is working (or reasonably foreseeable), and the project doesn't meet the F10 threshold | Where the project meets the HSE F10 notification threshold |
| Project responsibility | Does not itself make the supplier Principal Contractor | Principal Contractor responsibility | Principal Contractor |

Who typically requires a PCL
A Principal Contractor Licence is required specifically where a project crosses the HSE F10 notification threshold outlined above. In practice, this means PCLs are generally held by larger or more established rail contractors managing substantial projects directly for Network Rail, rather than smaller-scale or shorter-duration work, which may instead require a Principal Contractor Certificate (PCC).
Organisations pursuing a PCL will usually already have:
- Experience operating within rail environments
- Established management systems
- Dedicated health and safety competence
- Experience managing subcontractors and operational delivery
The process is therefore very different to organisations entering the rail sector for the first time through RISQS.
How the PCL process works
The Principal Contractor Licence process involves several stages.
This process applies specifically to PCL; a PCC follows a separate, less extensive route.
Before applying, organisations must hold a valid RISQS qualification, including completion of the Core, Sentinel, CDM and Safe Work Planning modules. A Network Rail Sponsor is also required as part of the application — this is a named individual within Network Rail who supports and sponsors the organisation’s licence application.
Typically, organisations are required to:
- Submit detailed management system documentation and evidence
- Demonstrate compliance with Network Rail standards
- Undergo formal assessment and review
- Complete face-to-face audit activity
- Demonstrate operational capability onsite before full approval
Successful organisations may initially receive provisional approval before further operational assessment takes place during live project delivery.
PCL holders are also reassessed regularly, with licences requiring ongoing renewal and continued compliance.
Why organisations often struggle
Many organisations underestimate how operationally focused the PCL process is.
The assessment is not simply reviewing whether policies exist. It examines whether organisations can demonstrate:
- Effective operational control
- Clear allocation of responsibilities
- Robust management of subcontractors
- Consistent application of safety procedures
- Evidence that systems operate effectively in practice
One of the most common issues is assuming that existing ISO certifications alone are sufficient.
While standards such as ISO 9001 or ISO 45001 provide a useful foundation, PCL requirements are built around the operational realities of working directly within a live rail environment and managing projects on behalf of Network Rail.
It is also worth noting that RISQS qualification, including the relevant modules, must be in place before PCL can be pursued. Organisations that have not yet achieved RISQS, or whose RISQS qualification does not cover the required modules, will need to address this as part of their preparation.
How JVR Consultancy supports PCL preparation
Our approach focuses on operational readiness rather than generic documentation.
Support typically includes:
Gap analysis and readiness review
We assess existing systems and operational controls against the expectations associated with Principal Contractor Licence assessment.
Management system development
Where required, we help organisations strengthen or adapt their systems to reflect Network Rail-specific operational requirements.
Audit preparation
We support organisations in preparing documentation, evidence and operational processes ahead of formal assessment activity.
Ongoing compliance support
As standards and operational expectations evolve, we help organisations review and maintain their systems to support continued compliance.
Operational responsibility in practice
A Principal Contractor Licence is ultimately about project-wide responsibility.
For example, where a footbridge replacement project is taking place over a live railway:
- The PCL holder may manage the overall site and operational control
- Subcontractors may deliver individual elements beneath them
- Responsibility for coordination, welfare, inductions and safe systems of work remains with the principal contractor
This is what differentiates PCL from supplier assurance schemes further down the supply chain.
Maintaining a Principal Contractor Licence
PCL approval is not static.
Network Rail standards evolve regularly, and organisations are expected to ensure their systems, procedures and operational controls remain aligned with current requirements.
Maintaining a licence typically requires:
- Regular review of operational procedures
- Ongoing monitoring of compliance
- Updates to management systems
- Continued demonstration of operational control
Organisations that treat compliance as an ongoing operational process are generally far better prepared for renewal and reassessment activity.

PCL Frequently Asked Questions
PCL stands for Principal Contractor Licence. It is Network Rail’s approval for organisations acting as Principal Contractor on Network Rail managed infrastructure where a project meets the HSE F10 notification threshold.
A PCL is required where an organisation is acting as Principal Contractor on Network Rail managed infrastructure and the project is HSE F10-notifiable. This applies where construction work lasts more than 30 working days with more than 20 workers simultaneously, or exceeds 500 person-days.
Both relate to organisations acting as Principal Contractor on Network Rail managed infrastructure. A Principal Contractor Certificate (PCC) applies where more than one contractor is working and the project doesn’t meet the HSE F10 notification threshold, while a Principal Contractor Licence (PCL) is required once a project meets that threshold.
No. RISQS is a supplier assurance and qualification scheme, while a PCL relates specifically to an organisation’s ability to act as Principal Contractor on qualifying Network Rail projects. Organisations pursuing a PCL must have the appropriate RISQS qualification in place as part of the process.
No. ISO certification provides a useful foundation, but it does not automatically meet PCL requirements. Organisations must demonstrate that their systems, controls and operational practices meet Network Rail’s requirements for managing work as Principal Contractor.
Yes. JVR supports both organisations preparing for their first PCL assessment and existing licence holders reviewing management systems, operational controls and compliance ahead of renewal or reassessment.
