Our Accreditations
•••Our recognised accreditations demonstrate the quality, reliability, and compliance you can expect from every Alkali Environmental service.
Accredited Standards You Can Verify
•••At Alkali Environmental, our accreditations reflect the care, precision, and integrity we bring to every project — and can be independently verified through UKAS, MCERTS and the relevant certification bodies.
Our MCERTS-certified stack emissions testing operates under UKAS Laboratory No. 24303. We also hold internationally recognised standards including ISO certifications and SafeContractor — credentials that provide assurance our work is delivered to recognised standards of accuracy and reliability.
These accreditations are an independent confirmation that our methods, systems, and results meet the benchmarks set by regulators and industry bodies.
For our clients, this means confidence in the data, advice, and compliance evidence we provide.
MCERTS Accreditation
What is MCERTS?
MCERTS is the Environment Agency's official certification scheme for monitoring emissions to air, land and water. It sets out strict requirements for how tests are carried out, the equipment used, and the competence of the people doing the work. Without MCERTS, monitoring data can't be relied upon by regulators. With it, your results are proven accurate, legally defensible, and fully compliant with UK environmental law.
Why it Matters to You
For businesses, the difference is huge. Using non-MCERTS data can mean permits being refused, results rejected, or projects delayed. Regulators will not accept stack emissions monitoring unless it is carried out under MCERTS. That's the law. Choosing MCERTS from the start protects your investment, avoids repeat testing costs, and keeps your operations running smoothly. In short: MCERTS saves you time, money, and risk.
Why Choose Us
At Alkali Environmental, MCERTS is not a sideline — it's our core specialism. Our team are accredited to perform stack emissions testing, ambient air quality assessments, and reporting that satisfies the Environment Agency first time. With over 40 years of combined experience, including former EA officers and industry specialists, we understand the regulations inside out. That means fewer surprises, smoother audits, and confidence that your compliance is rock-solid.
UKAS Accreditation
What is UKAS?
UKAS (the United Kingdom Accreditation Service) is the national body appointed by government to assess and accredit organisations that carry out testing, inspection, and certification. A UKAS-accredited laboratory has been independently verified to meet strict international standards, ensuring the accuracy, consistency, and reliability of its results. Without UKAS, data lacks independent assurance and can be called into question.
Why it Matters to You
Regulators, courts, and government agencies trust only UKAS-accredited results. For environmental testing, that means your emissions data, air quality reports, or chemical analyses stand up to legal and regulatory scrutiny. Without UKAS, you risk results being challenged, permits delayed, or compliance action taken. Choosing a UKAS-accredited partner ensures your evidence is defensible and your projects keep moving.
Why Choose Us
At Alkali Environmental, our laboratory services are UKAS-accredited, giving you the confidence that every analysis we provide is independently verified to international standards (ISO/IEC 17025). Combined with our MCERTS expertise, this means your testing is both regulator-approved and scientifically robust. Our clients rely on us for accurate data, clear reporting, and results that withstand the toughest scrutiny — because UKAS is not just a logo, it's proof of trust.
ISO/IEC 17025 Accreditation
What is ISO/IEC 17025?
ISO/IEC 17025 is the internationally recognised standard for the competence of testing and calibration laboratories. It sets rigorous requirements for laboratory management systems, technical procedures, equipment calibration, staff competence, and the validity of results. Accreditation to ISO/IEC 17025 is granted in the UK by UKAS and is the benchmark that regulators, courts, and international bodies use to judge whether laboratory data is technically reliable.
Why it Matters to You
ISO/IEC 17025 is what turns a laboratory result into evidence that stands up under regulatory and legal scrutiny. Without it, data can be challenged, permits delayed, and reports rejected. With it, your results carry international recognition through the ILAC Mutual Recognition Arrangement — accepted in over 100 countries. For UK operators, it means the Environment Agency, SEPA, NRW, and local authorities will accept your data without question, and your compliance evidence is defensible in enforcement or planning appeals.
Why Choose Us
At Alkali Environmental, our testing and analysis operates within an ISO/IEC 17025-accredited framework under UKAS Lab No. 24303. Every sample, calibration, and reported result follows documented procedures, validated methods, and full traceability to national standards. This is the technical backbone that supports our MCERTS stack emissions testing and laboratory analysis — giving you confidence that the numbers on your compliance report are accurate, repeatable, and legally defensible.
Safe Contractor Approved
What is SafeContractor?
SafeContractor is a health and safety accreditation recognised across the UK. Run by Alcumus, it independently verifies that a company follows best practice in health, safety, and risk management. It's one of the UK's most widely respected contractor accreditations, showing clients that your business operates safely and responsibly.
Why it Matters to You
When you hire a SafeContractor-approved company, you reduce your own risk. Many major organisations, including councils, developers, and blue-chip companies, now require SafeContractor accreditation before awarding contracts. Without it, businesses can lose opportunities and fail to meet supply chain standards. With it, you gain reassurance that all work is carried out to the highest safety standards.
Why Choose Us
At Alkali Environmental, SafeContractor approval proves that we don't just deliver technical excellence — we deliver it safely. Our accreditation demonstrates that our people, processes, and systems meet rigorous safety requirements. For clients, this means fewer worries, smoother onboarding, and complete trust that compliance is built into every project from day one.
STA Testing
What is the STA?
The Source Testing Association (STA) is the UK's leading technical body for stack emissions monitoring. It brings together regulators, industry experts, and testing organisations to set best practice, share knowledge, and raise standards across the industry. STA membership shows that a company is committed to staying at the forefront of emissions testing.
Why it Matters to You
Environmental regulation moves fast. By working with an STA member, you gain access to the latest methods, guidance, and regulatory updates — ensuring your monitoring is always compliant with the most current requirements. For clients, this means fewer risks, no nasty surprises, and results that reflect the very latest in industry standards.
Why Choose Us
At Alkali Environmental, our STA membership reinforces our position as industry specialists. It means we're actively involved in shaping guidance, improving methods, and driving higher standards in emissions testing. For you, it means a partner who's not just compliant — but ahead of the curve, ensuring your projects meet both today's and tomorrow's requirements.
