Frequently asked questions
Can Alkali deliver the same MCERTS stack emissions testing as SGS in the UK?
Yes. Alkali is UKAS-accredited testing laboratory 24303 and MCERTS-accredited for stack emissions monitoring, with UK-wide delivery from Leeds and Swindon.
When should a UK operator pick Alkali instead of SGS?
When stack emissions, air quality and environmental permitting are the primary need and the operator wants a specialist independent UK partner rather than a global multi-sector TIC.
