NPL's aim is to meet customers' needs by providing services that are undertaken to the highest professional standards, represent value for money and are delivered on time.

We shall pursue this aim through implementation of a Quality Management System involving all staff that will require us to:

  • 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/IEC 17043:2010 or ISO 17020:2012 (Type A) where accredited and/or ISO 9001:2008 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.
