Phenna Group acquires 4Fores

Dec 20: Headquartered in the UK, Phenna Group has grown rapidly over the last few years to become one of the world’s leading Testing, Inspection, Certification and Compliance (“TICC”) businesses by partnering with independent companies serving a variety of key, mission-critical sectors around the globe.

We are delighted to announce the acquisition of 4fores (For Optimal Renewable Energy Systems S.L.), a well-established and long-standing provider of testing, measurement, and grid integration solutions for renewable energy systems. This acquisition is our 24th deal of 2025 and continues our ambitious programme of international expansion. 4Fores marks Phenna’s entry into Spain, following the group’s establishment this year of a meaningful presence in Italy. And reinforces our commitment to building a broad-based international group of high-quality businesses.

4fores enhances Phenna Group’s Industrials Division capabilities, bringing expertise in renewable energy testing and compliance as global growth in wind, solar, and distributed energy systems accelerates. The acquisition provides Phenna with an established international platform, strong technical talent, and a differentiated service offering within an increasingly regulated sector.
