Part of PTSG
The ECS Group (ECS) 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.
ECS forms a major part of PTSG Electrical Services Ltd. ECS has strengthened the breadth and depth of PTSG’s service offering as well as its geographical reach.
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 2,300 people across 46 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 ECS, which also benefit from the backing and resources of Warburg Pincus and Macquarie Capital.

“ECS have assisted us with our EICRs (Electrical Installation Condition Reports) over the last few years. They have completed electrical safety tests in both our general needs properties as well as our larger Retirement Living and Flexi Care Schemes. They provide an extremely efficient and professional service. ECS have a full understanding of what we require from them and provide full and detailed certification as well as extensive photos of each site. All the engineers are fully qualified and have current DBS certification provided for each operative before any programme gets underway.
We would have no hesitation in recommending ECS to other Housing Associations and trusts.”
