Our Philosophy
All the expertise. Always independent. From precious metals to product safety and authentication. 253 years of impartial expertise, all in one place.
Protecting integrity. Enabling confidence. Supporting progress.
For more than 250 years, Birmingham Assay Office has existed to protect trust in materials, products and supply chains. First across the jewellery industry, now far beyond it.
From our historic role in hallmarking precious metals to our modern UKAS-accredited analytical testing laboratory, we have always served the same purpose: providing independent verification where confidence matters most. Today, organisations across manufacturing, retail, technology, recycling and global supply chains rely on accurate, independent data to support critical decisions. Our promise is to deliver exceptional quality across a diverse range of services, all under one roof.
Our Mission
We protect consumers through collaboration, delivering innovative test and certification services for compliance.
Great quality comes from an unwavering commitment to the smallest details, and the kind of customer service you can always rely on.
Our heritage inspires the foundation for a future of limitless possibilities.
Our Philosophy
Three pillars of Birmingham Assay Office guide every service we deliver, every certificate we issue and every relationship we build.
Independence
- Established under the Hallmarking Act 1973, Birmingham Assay Office operates with a statutory duty to remain independent of the industries we serve. We have no commercial interest in the outcome of any test or assessment we conduct. Our only interest is accuracy.
Expertise
- With a heritage spanning over 250 years, our wealth of industry experience is unparalleled. From precious metal standards and gemmological assessments to GPSR compliance, analytical chemistry and EV battery analysis, our scientists, valuers and specialists bring genuine depth to every discipline we practise.
Integrity
- Every certificate we issue carries our name and our statutory standing. We do not cut corners, we do not favour clients, and we do not allow commercial pressures to influence our results. Our integrity is the foundation on which 252 years of institutional trust has been built.
Our Values
Four principles define how we work and why organisations across the UK and beyond trust Birmingham Assay Office with their most critical testing and certification needs.
Meaningful Relationships
- We believe the best work happens through genuine partnership. We invest in understanding your business, your industry and your specific needs, building lasting relationships that go far beyond a transaction. Many of our clients have worked with us for decades. Some for over a century.
Dependability You Can Count On
- When a certificate needs to stand up to a regulatory, an insurer or a commercial counterparty, you need to know it will hold. We meet our turnaround commitments, respond to every enquiry within 48 working hours, and deliver results you can rely on every time, without exception.
Embracing Innovation
- From AI-assisted luxury goods authentication through Valued & Vaulted, to ICP-OES analysis of black mass and EV battery materials, we have always been early adopters of the methods that matter most to our clients. 253 years of heritage has never been a reason to stand still.
Unwavering Dedication
- Great quality comes from an unwavering commitment to the smallest details. From the precision of our analytical methods to the care we take in every client interaction, we do not compromise, we do not cut corners, and we deliver reliable accurate results.
Our Commitment
We apply three commitments to every service we deliver and every organisation we work with.
Impartial results, every time.
- Our independence means we have no financial interest in the outcome of any test we conduct.
Exceptional quality, delivered on time.
- Great quality comes from an unwavering commitment to the smallest details. We meet our turnaround commitments and respond within 48 working hours.
Accessible to everyone, everywhere.
- You send it, we certify it. Any courier, any country. Post your submission for any of our services from anywhere in the world.
