Posted on July 5, 2023 By

Benchmark International is pleased to announce the acquisition of Marlborough-based Trident Water and Nottingham-headquartered Phenna Group.

Trident Water was established in 2002 and is a water treatment and water hygiene specialist with a focus on legionella control. With a wide and varied client base across a range of sectors, Trident Water is currently a trusted partner at over 200 sites across the UK.

Phenna Group's aim is to invest in and partner with selected niche, independent testing, inspection, certification and compliance (TICC) companies that serve a variety of sectors. A highly acquisitive group, this is Phenna’s eighth acquisition this year, further augmenting its market leading built environment platform, and adding geographic reach and complementary services to its existing offerings.

Since first meeting Paul and his team, they have acted with great transparency and integrity; values which were very important to us in making our decision. Angela and I are convinced that Phenna Group will provide exactly the support Andy and the team needs to deliver our future growth plans and maintain the quality of our offerings.
