Promera Buys Two UK Firms to Expand Data Center Cleaning Reach

Promera has completed the acquisition of Formula Facilities Services Ltd. and Critical Area Cleaning Ltd., creating a new service platform across the United Kingdom and Ireland. The deal expands the company’s international footprint and follows its earlier entry into Asia. By combining these two firms, Promera now offers services that cover the entire lifecycle of a data center, from initial construction to daily operations.

The financial details of the transactions were not disclosed. Promera, which is backed by Angeles Equity Partners, provides essential technical services to hyperscale and enterprise data center customers. The acquisitions allow the company to serve clients whose infrastructure increasingly spans multiple international markets, a trend accelerated by the global rollout of artificial intelligence systems.

Complementary skills in contamination control

The two acquired companies handle different stages of the data center process. Formula specializes in maintaining operational facilities, focusing on critical environment maintenance for active data centers. It has long-standing relationships with colocation providers and facility management customers. Critical Area Cleaning, or CAC, focuses on the construction phase. It works with major general contractors to manage contamination and white-space maintenance before and after a facility is built.

Together, these capabilities allow Promera to support customers across the full data center lifecycle. As data centers become larger and more densely packed with computing equipment, controlling contamination is critical for maintaining reliability and uptime. This is particularly true in AI-driven environments, where higher computing densities create more complex thermal and particulate challenges.

Leadership changes to drive growth

Promera has appointed Jim Harding as Managing Director, International. Harding will lead the company’s operations in Europe and Asia. He has been on the board for about 18 months and brings over 25 years of experience in digital infrastructure. Most recently, he led Colovore’s entry into the European market, where the company specialized in liquid-cooled infrastructure for AI workloads.

Harding previously spent a decade at CBRE, where he served as Global President of Data Center Solutions. In that role, he oversaw a global business supporting critical environment operations in more than 700 facilities across 50 countries. The owners of the acquired firms, Martin Glennon and Jack Rowley, will continue to lead their respective operations and report directly to Harding.

Global reach and strategic context

This expansion follows Promera’s acquisition of Data Clean Asia in Singapore, which established its presence in the region. With the addition of Formula and CAC, the company now has regional capabilities across North America, Europe, and Asia. This geographic spread is designed to help data center operators manage their critical environments consistently, regardless of location.

Promera has more than 45 years of experience supporting digital infrastructure. The company provides technical services including contamination control, airflow management, and white-space fit-out. Alston & Bird served as legal counsel for the transactions, while Portman Partners advised on the Formula acquisition. The move underscores the growing importance of specialized cleaning and maintenance in the era of high-density computing.
