UKAS-Accredited Odour Testing Laboratory & Sampling Services
Choosing an odour testing laboratory that offers UKAS-accredited sampling and analysis is essential for reliable results. Accreditation ensures your data is accurate, defensible and compliant with BS EN 13725:2022.
As a specialist odour testing laboratory, we provide accredited sampling and analysis. Our work supports planning, permitting and environmental compliance across the UK.
What UKAS Accreditation Means for Odour Measurement
UKAS is the UK’s national accreditation body. It independently confirms that odour testing laboratories meet recognised standards of competence and quality.
For odour measurement, accreditation follows internationally recognised frameworks, including:
- BS EN 13725:2022 – the European standard for odour measurement
- ISO 17025:2017 – laboratory quality management systems
UKAS Accreditation & Data Confidence
For planning, permitting or regulatory purposes, odour data must be robust and defensible.
UKAS accreditation provides assurance that:
- Olfactometry results are repeatable and reproducible
- Methods are applied correctly and uniformly
- Data is independently assessed
- Reports are suitable for regulatory review

How Odour Sampling & Laboratory Testing Works
A complete odour measurement programme typically includes both sampling and odour testing laboratory analysis.
We collect a range of odour samples from specific sources on-site and return them to the laboratory.
Laboratory Testing (Olfactometry)
Samples are analysed in our specialist laboratory using dynamic olfactometry to determine odour concentration.
Laboratories process and report all results according to recognised standards. As a result, odour emissions data is accurate and reliable.
Maintaining Quality in the Odour Testing Laboratory
In an odour testing laboratory, UKAS accreditation is not a one-off achievement. It requires continuous assessment and verification.
At Silsoe Odours, this includes:
- Regular independent audits of our odour testing laboratory and sampling procedures
- Participation in annual proficiency testing for UKAS-accredited laboratories
- Ongoing training and screening of odour panel members
- Strict control of laboratory conditions and equipment calibration
These processes ensure our results remain consistent, reliable and aligned with best practice.
