Independent Services


Together with our subsidiary, AEGIS Certification Services Ltd, we offer a full range of third-party independent assessment and certification services. These include:

Our team has a wealth of experience in applying legislative requirements. We’re always on hand to support you in securing safety approvals and authorisations for rail vehicles, infrastructure, plant and machinery. We adopt a pragmatic approach whilst maintaining the necessary level of independence and impartiality.

Fully accredited

AEGIS is accredited by UKAS to BS EN ISO/IEC 17020:2012 as a Type C Inspection Body and to BS EN ISO/IEC 17065:2012 as a Certification Body. The rigorous accreditation process examined our processes and competence across all railway engineering disciplines and TSI areas. We have a broad knowledge of supporting technical and process standards including BS EN 50126, BS EN 50128, and BS EN 50129.

Independent Safety Assessment and Audit

We have a proven track record in undertaking Independent Safety Assessment (ISA), having become one of the first Network Rail approved ISAs in 2002. We begin the ISA process at the start of a project or product development, allowing any safety concerns to be managed at an early stage and controlled with minimal impact.

We adopt a risk-based approach to focus effort on the areas of greatest concern or uncertainty. The ISA typically comprises the formal assessment of a project’s safety deliverables (safety plan, hazard identification, risk assessment and safety case) and supported by safety audits.

Example projects have included LOTRAIN, software for Class 345 Crossrail trains, Class 378/379/387 Cat A Modifications and ATC Signalling for SSL.

Assessment Body

AEGIS is accredited to act as an Assessment Body (AsBo) in accordance with Regulation (EU) 402/2013 (and (EU) 2015/1136 amendment) on the Common Safety Method for Risk Evaluation and Assessment (CSM RA). The role of the AsBo is to assess the suitability of the risk management process and the results of the process, which is presented in a Safety Assessment Report. This regulation applies to technical, operational and organisational safety-related changes to the railway, and requires that an AsBo is appointed if the defined change is determined to be ‘significant’ to operational safety.

Example projects include Class 345 Crossrail trains, C44 Rail Grinders, Class 465 Regen, Channel Tunnel ElecLink, Amey Level Crossing product development and SSL ATC signalling.

 Notified Body

AEGIS has been appointed by the DfT as a Notified Body (NoBo) against the rail interoperability Directive 2008/57/EC, and we are able to undertake certification against all of the structural and transverse Technical Specifications for Interoperability (TSIs), including Rolling Stock (LOC & PAS), Control-Command and Signalling (CCS), Energy (ENE), Infrastructure (INF), Noise, Persons with Reduced Mobility (PRM) and Safety in Railway Tunnels (SRT).

We offer certification of new and modified vehicles and infrastructure, including interoperability constituents. Our team has considerable experience of different project types and can offer guidance on the compliance demonstration process, selection of the conformity assessment modules and construction of the Technical File.

Designated Body and Verification of Engineering Change to Rail Vehicles

In addition to being a Notified Body, AEGIS is also appointed by the DfT as a Designated Body (DeBo) to assess conformity against the Notified National Technical Rules (NNTRs).

Our BS EN ISO/IEC 17065:2012 accreditation covers undertaking independent verification activities under RIS-2700-RST (Rail Industry Standard for Verification of Conformity of Engineering Change to Rail Vehicles).  This replaces the superseded Vehicle Acceptance Body role, and involves the verification of the design and construction (including maintenance arrangements) against requirements within Railway Group Standards, resulting in a formal Attestation Statement.

Example projects include RIS-2700-RST verification for a variety of clients including Bombardier, dG8, Southeastern and Abellio Scotrail.

Plant Assessment Body

The scope of our accreditation to BS EN ISO/IEC 17065:2012 also includes the ability to undertake Plant Assessment Body (PAB) reviews in accordance with RIS-1710-PLT (Rail Industry Standard for Engineering Certification of Railborne Plant). Our team offers assessment and certification of On-track Machines (OTM) and On-track Plant (OTP).

Example projects include a wide range of manufacturers and engineering companies including Allan J Hargreaves Plant Engineers Ltd, Fitzgerald Plant Services Ltd, Rail Products UK Ltd and SRS SRS Sjölanders AB.

 Independent Competent Person

Under the Railways and Other Guided Transport Systems (Safety) Regulations 2006 (ROGS), non-mainline transport operators need procedures to cover safety verification of new or altered rolling stock or infrastructure.

Within the safety verification process, AEGIS has experience of acting as the Independent Competent Person (ICP) to support the duty-holder in establishing and following suitable processes for safety.
