Atesta

What Atesta does

Atesta is a UK-based professional services firm that delivers MCERTS accredited stack emissions testing to permitted and regulated industrial sites. Its core service involves on-site measurement of air emissions from industrial stacks, providing the accredited verification that operators need to demonstrate compliance with regulated emission limits and to keep their permitted facilities operating without interruption. Beyond stack testing, the company offers occupational hygiene services and environmental consultancy, although its commercial identity and leadership narrative are anchored to stack emissions testing.

The underlying capability combines state-of-the-art physical testing equipment with specialist, highly experienced field staff whose technical qualifications underpin MCERTS accreditation - a sector-mandated certification issued under the UK's Environment Agency framework. Sales and delivery rest on deep industrial relationships rather than digital channels, and are driven by Business Development Director Alastair Wolff, who brings 30 years of emissions testing experience and a track record of having established and led the two largest MCERTS accredited testing companies previously operating in the UK. The company has historically focused on retaining customers through quality of service and turnaround time rather than price competition.

Atesta operates a project-based B2B professional services model, billing permitted-site operators for individual testing engagements rather than recurring software or platform fees. Pricing is quote-based and not publicly disclosed. In October 2024, Atesta was acquired by Cura Terrae OH and Emissions Testing, the parent of Envirocare, reuniting leadership teams and folding Atesta into a multi-location UK group with teams in Warrington, Bradford, Brackley, East Kilbride, and Newcastle. Following the deal, Atesta continues to trade as an acquired brand within the Cura Terrae environmental services group, serving the same regulated industrial end market with expanded geographic coverage and access to adjacent occupational hygiene and consultancy capabilities.
