Frequently Asked Questions

Promera has acquired Formula Facility Services and Critical Area Cleaning. Both businesses are now part of Promera's UK platform, joining Promera's existing operations in North America and Asia-Pacific.

Formula’s operational maintenance expertise and CAC’s construction-phase contamination-control capabilities create more consistent support as facilities move from construction and commissioning into ongoing operations. Promera adds broader technical resources, international experience and additional services for critical environments.

No. Continue working with your team as usual and contact your existing relationship lead with any questions. We will communicate any administrative updates clearly and in advance.

Over time, you will see the Promera name appear on uniforms, vehicles and documents, though the same people, teams, standards and contracts stay in place. We will give plenty of notice before anything changes visibly on client sites.

Promera delivers technical solutions across the full data center lifecycle, from construction and commissioning through live operations. The company specializes in contamination control, critical environment maintenance, white space fit-out, and airflow and energy management, serving hyperscale operators, colocation providers and enterprise clients across North America, Asia and now Europe.

With more than 45 years in business, ISO 9001 and ISO 14001 certified management systems, zero recordable incidents in 2026, and safety performance ratings that exceed industry benchmarks, Promera is a trusted partner for the world’s most demanding digital infrastructure environments.
