Approved manufacturers are manufacturers of weighing and measuring equipment whose quality system has been accredited by a UK Approved Body primarily under the Module D or D1 conformity assessment procedure, as set out in the Non Automatic Weighing Instruments Regulations 2016 (as amended) or Measuring Instruments Regulations 2016 (as amended). Approved manufacturers can complete initial verification of instruments as set out in their accredited quality system.

Some approved manufacturers for the Non-automatic Weighing Instruments Regulations 2016 can have their quality system accredited by a UK Approved Body under Module D or D1 for the purposes of requalification of instruments they have manufactured.   Email one of the following Approved Bodies for further details:




Once accredited, your details will be passed to the Secretary of State within the Office for Product Safety and Standards (OPSS), which will then add you to the list of approved manufacturers below. Any approved manufacturer that does not maintain its accreditation shall be removed and thereafter be unable to undertake verification activities.
