Our Values

NPL's Values

We remain committed to our values which are aligned with the public mission of NPL; the need to develop creative and committed staff, who feel empowered to deliver the best science and service to stakeholders; and the creation of a work environment that people enjoy and in which they feel valued.

We shall pursue these aims through the implementation of a Quality Management System, involving all staff members, which will require us to:

  • Be aware of the role and objectives of the Laboratory and how our functions contribute to them;
  • Recognise that our work is undertaken for customers, internal and external, whose needs we should understand and meet;
  • Work to the highest professional standards supported by written procedures and monitored against explicit criteria of quality;
  • Seek and receive the necessary training to fit us for our work.

We shall provide our customers with a service which meets the requirements of ISO 17025:2005 (including ISO Guide 34 or ISO 17043:2010, where accredited) and/or ISO 9001:2008 and TickITplus, as appropriate.

We shall promote a collective commitment to good professional practice and continual improvement in the quality of our services. The actions necessary for improvement shall be implemented and their effectiveness shall be monitored.

We shall be aware that responsibility for awareness of and compliance with the quality system rests in the first place with everyone. We shall familiarise ourselves with the documentation and implement the policies and procedures in our work.

Senior management shall ensure that customer needs and expectations are determined, converted into requirements and fulfilled with the aim of achieving customer satisfaction within the bounds of statutory and legal requirements.

Each member of staff is responsible for the quality of their work and for satisfying their customers' requirements, stated and implied.

Regardless of our type of work, we shall comply with the policies set out in the NPL Quality Manual except under clearly defined conditions. These conditions shall be recorded and authorised.
