Part of PTSG Group


Trinity is part of Premier Technical Services Group Ltd (PTSG), one of the UK’s leading providers of niche specialist services across a range of sectors.

PTSG operates five independent business divisions, which can also combine to deliver a complete specialist services solution: PTSG Access & Safety Ltd, PTSG Electrical Services Ltd, PTSG Fire Solutions Ltd, PTSG Water Treatment Ltd and PTSG Building Access Specialists Ltd.

Trinity forms a major part of PTSG Fire Solutions Ltd and is one of the largest constituent companies within the Group as a whole. Trinity has added a number of extra services to PTSG’s core services including the supply, installation, commission, training and long-term aftercare of fire detection and life safety systems; restaurant fire suppression (installing and maintaining Ansul R102 systems across the UK); and security services including intruder alarms, CCTV, access control and bespoke security systems.

In May 2021, leading global growth investor, Warburg Pincus, announced that it had entered an agreement with Macquarie Capital Principal Finance (“Macquarie Capital”) to jointly acquire a majority stake in PTSG. This investment marked a significant milestone for the Group, allowing them to focus on continued innovation and key growth initiatives, while continuing to offer strong customer service.

Headquartered in West Yorkshire, England, PTSG employs over 2,400 people across 47 UK sites, servicing more than 200,000 buildings in the UK, across a wide range of industries.

The partnership between Warburg Pincus and Macquarie Capital supports PTSG’s development, providing the firm with additional resources and funding to accelerate its strong organic growth and consolidation strategy – with the goal of occupying a greater share of the UK’s compliance services market.

Macquarie Capital acquired a majority stake in PTSG in 2019 in a take-private transaction. Since then, PTSG has benefitted from access to Macquarie Capital’s flexible balance sheet funding, which has allowed the company to continue with its ambitious growth strategy, driven by its founding management team.

The agreement significantly strengthens the position of all constituent companies within PTSG, including Trinity, which also benefit from the backing and resources of Warburg Pincus and Macquarie Capital.
