Authorising Engineers


TSA provide independent discipline-specific Authorising Engineers to take responsibility for the effective management of high risk systems within buildings such as high voltage or dual-fed supplies, steam/hthw, and confined spaces, in compliance with:


  • Ministry of Defence Standards (JSP375)
  • Health Authority Standards (HTM06-02, 06-03, 03-01)
  • Client Specific Standards


We review your existing procedures, develop Safe Systems of Work, audit your operational procedures and appoint suitable Authorised Persons to manage the risks on site.


We undertake audits, surveys, compile SOPs, and provide advice and support.


We currently manage 145 APs across 40 sites.
