Welcome to QSL

QSL are a innovative engineering consultancy providing a broad range of services within the pharmaceutical and chemical manufacturing industries.
Our team has gained a wealth of experience across many leading, blue-chip, global organisations. We advise companies on best industry practices and implement change.

Our approach is simple, we listen to our clients’ needs and give them clear direction. We pride ourselves in our ability to offer niche turnkey services–in fact, it’s where the business started. We were formed in 2007 when we recognised how difficult it was to find an engineering consultancy who really understood the workings of a busy engineering department within the pharmaceutical / chemical manufacturing sectors. Our success is built on lasting relationships and repeat business. This allows us to develop in-depth understanding of client needs and tailor our services to provide efficient engineering solutions that add real value. We have the skills and experience to confidently embark on challenging and technically demanding projects. QSL is a unique collection of likeminded pragmatic professionals with a common ambition to deliver a top-quality service that always meets our client’s needs. Our core services in consultancy are maintenance life planning and equipment criticality assessment; CMMS configuration; and management of hazardous area equipment. These services are enhanced by the specialist services of Computer System Validation and OT Cyber Security.

Information Sharing

We ensure that the information you share is necessary for the purpose for which you are sharing it, is shared only with those people who need to have it, is accurate and up-to-date, is shared in a timely fashion, and is shared securely..

Highly Trained Team

Training helps to make people more confident in their role, which directly improves morale. It is important in maintaining morale that staff are trained equally. Better training means better processes. Tasks can be performed much faster if employees know what they're doing and the quality of work will also improve

Safety Certified

We ensure that job sites are hazard-free and that employers provide optimal working conditions for employees. These professionals also ensure that buildings or products comply with health and safety regulations, and they examine employee safety programs.
