The following contains current and previous projects, presented courtesy of the companies involved.

Royal Botanic Gardens, Kew
Implementing ISO 14001

We have been working with both Nick and Cathy since early/mid 2004 when The Royal Botanic Gardens, Kew decided to investigate the  SO14001 standard.


We were aware that the Royal Parks had just successfully taken that route and through our close connections discovered who had assisted them. We asked Passingham Associates to make a senior management presentation and following on from this engaged them to work with us on a consultancy basis.  This has been extremely successful and saw RBG Kew becoming the first World Heritage status site to achieve the standard and all within 18 months which we feel was very fast considering the complexity of our site and operations. Throughout the process both Nick and Cathy have shown themselves to be everything we could have wished for and have very quickly come to understand how RBG Kew works. I have made a
number of presentations about our achieving ISO14001 to similar organisations as ours and am more than happy to recommend Passingham Associates. We continue to work with them on maintaining the standard and are beginning discussions about increasing the scope of the award to cover other sites.

Oil Spill Response Limited

Implementing a full integrated management system: ISO
9001/ ISO 14001 / ISO 45001


OSRL/EARL engaged Passingham Associates to support us in the development of an Integrated Management System under ISO9001, ISO14001 and ISO45001 for our UK operations.
We have found Passingham Associates to be both professional and pragmatic in their application of the standards and have been impressed with the time they have taken to understand our business properly.  We now have an Integrated Management System which augments our business processes rather than being an unwanted layer of bureaucracy. I have no hesitation in recommending Passingham Associates.

I have no hesitation in recommending the services of Passingham Associates as being professional, efficient and cost effective. In addition both Nick Passingham and Andy Watts are a pleasure to work with and extremely knowledgeable in their respective fields.
