Quality Accreditations 


Accredited since 1992 with a recognised international quality system, the company now has BS EN ISO 9001:2015 Quality Management System. This requires a process of Continual Improvement in all areas of the business and it's procedures are audited by BSI on a six monthly basis and we have an exemplary record in such audits over many years. West & Senior are delighted to anounce that they have achieved (in August 2016) the ISO9001:2015 Quality Managment System accreditation. One of the first Companies to be awarded this accreditation in the UK Chemical Industry.

Unfortunately Technical Specification Sheets are not available on this web site due to the vast range of products that we manufacture. If you require a specific or generic Technical Specification Sheet or any other quality information please contact our Quality Manager at:
