Rail Assurance Schemes

Is your organisation looking to become an Assured Rail Supplier?


Are you already registered and looking to increase the product groups you already hold?


If so, PRB Consulting are experts in the Assurance Process. Our in-house team have a wealth of experience and knowledge in this area and comprises former assurance auditors.


PRB have assisted many organisations through this process and undertake more than 120 audits each year and we are proud of our 100% success rate.

From April 2021 there are now two routes to rail assurance, RISQS and Achilles Link-Up. Both schemes offer the Core, Sentinel, CDM and Safe Work Planning modules. However, suppliers looking to provide services directly to Network Rail will be mandated to use the RISQS assurance process.

If you are seeking to achieve qualification via audit or increase your current product codes maybe, we can help. Our consultants have the experience and knowledge of the process to guide your business to a successful outcome.


Following the changes in September 2020, RISQS have altered the audit process, IMR has split into two modules now known as “Core” and “CDM” modules. All companies are now required to undergo the Core Module in the new format. This will look at ensuring organisations have a documented management system in place, along with its supporting procedures, to fall in line with the latest Network Rail Standards

Construction Design Management (CDM)

Prior to September 2020 CDM was incorporated within IMR, this has now been split into its own individual module. Only companies which deal in Construction Design Management will be required to be audited against this module.

Sentinel Scheme

Do you wish to sponsor and train your staff? To do this you will need to obtain a pass of the Sentinel Audit Requirements. This module will ensure your organisation has robust procedures that meet and comply with the requirements of the Sentinel Scheme Rules.

Safe Work Planning (SWP)

Do you plan access onto Network Rail Managed Infrastructure? If so, you are now required to be audited against compliance to NR|L2|OHS|019 for access’s planning.


PRB Consulting are approved Track Access Planners – maybe we can undertake this on your behalf.

On Track Plant (OTP)

Prior to September 2020 this module was known as “Plant Operator Scheme” or (POS). This module is applicable to suppliers who supply, hire, operate, maintain, overhaul, manufacture or convert on-track plant.
