As Authorising Engineers, or independent consultants for Engineering systems, we support our clients by advising, developing, implementing and monitoring Safe Systems of Work (SSoW). These are required to ensure technical compliance with the respective statutory regulations including; Electricity at Work Regulations 1989, Pressure Safety System Regulations 2000, Confined Spaces Regulations 1997 and Working at Height Regulations 2005.

Acting as an autonomous advisor means our advice is impartial and supports our clients to achieve an improved standard of compliance.

The professional status and role required of the Authorising Engineer may vary in accordance with the specialist engineering service being supported.

Authorising Engineer Consultancy


Following the principles of the Authorising Engineer role, where no process exists, we can offer the client advice, and support, in establishing a cost-effective Safe System of Work methodology, within their organisation.

For those clients who already have the methodology in place, we can offer assistance in the review of safety documentation, as well as assisting in the auditing and assessment of personnel, should the need arise.

As members of The Institution of Engineering and Technology (IET), The Institution of Healthcare Engineering and Estates Management (IHEEM), Society of Operations Engineers (SOE), and other professional accredited bodies, the services we provide can be in accordance with either the MOD Joint Services Publication (JSP) 375 Part 2 Volume 3 Series, the suite of Health Technical Memorandums (HTM) or bespoke customer safety rules and procedures.

Electrical Discrimination Studies


Electrical Discrimination Studies (Selectivity in accordance with BS7671) are carried out to ensure adequate protection of electrical systems and the safety of service provision.

This is to limit disruption to the electrical infrastructure by finely tuning protective devices to activate correctly and minimising business disruption and downtime in the event of fault or overload.

Electricity at Work Regulations 1989 recommend reviewing discrimination every 5 years or; following any significant change to the system.

Following a detailed, on-site survey of the installed electrical equipment, our clients are provided with a written report accompanied with system line diagram and grading chart along with recommended protection device settings, which will provide an appropriate level of discrimination for fault and overload protection for the HV system characteristics.

Although not limited to, a typical study includes:


  • 1. A protection discrimination study of the HV system will include the first LV breaker from each transformer and all HV devices through to and including the District Network Operator protection device

  • 2. A fault flow level study on the HV system; and,

  • 3. A load flow level study of the HV System

Our AP services can be used to support a business which has an immediate resource issue or offer guidance and bespoke mentoring services to prospective company APs.
