Notified bodies: appointment and co-ordination

Apply to become a notified body or identify a notified body.

How to become a notified body

Under the new approach directives on non-automatic weighing instruments (NAWI) and measuring instruments (MID) the United Kingdom has statutory obligations to ensure that conformity assessment schemes operate effectively.

The Secretary of State is responsible for the appointment or designation of notified bodies to undertake duties as set out in the regulations. In order to assist bodies requiring to become a notifed body, the Office for Product Safety and Standards (OPSS) has produced guidelines on the appointment of notified bodies under NAWI and MID. The guidance also includes an application form at the end.

Find a notified body

Notified bodies are third party organisations that have been appointed by a European Union (EU) member state competent authority following completion of an in-depth assessment. The primary role of a notified body is to provide services for conformity assessment on the conditions set out in the new approach directives in support of CE (conformity european) marking. Conformity assessment can be inspection, quality assurance, type examination or design examination, or a combination of these. This area provides information for the ongoing operation of a notified body, a search tool facility and information on how to report issues relating to a notified body.

OPSS maintains an up to date search engine to help identify notified bodies and which types of equipment they initially verify.

Notified body search engine

The new approach notified and designated organisations (NANDO) information system allows you to search for notified bodies across the EU.


Maintaining notified body status

OPSS has developed a protocol to assist notified bodies in maintaining their status through the peer auditor scheme. We also maintain a spreadsheet to assist in identifying appropriate peer auditors and an audit form and ISO 17020 checklist. The protocol lays down a framework through which local authorities wishing to operate as notified bodies (approved bodies) for the task of EC verification under NAWI and MID can be independently audited. It also allows for OPSS on behalf of the Secretary of State to be satisfied that the core criteria of directive 2009/23/EC and 2004/22/EC continue to be adequately fulfilled.

Market surveillance

OPSS is responsible for market surveillance activities under the new approach metrology directives covering NAWI, water meters, measuring systems for liquids other than water, capacity serving measures, length measures and automatic weighing instruments.

Desired outcome

OPSS on behalf of the UK has a statutory duty under the metrology directives to ensure that all appropriate measures are taken to ensure that measuring instruments that are subject to legal metrological control but do not comply with the applicable provisions of the directives are neither placed on the market or put into use.

Enforcement policy

OPSS works with notified bodies, inspection authorities and individual manufacturers and importers to achieve the desired outcome of the directives. We employ a variety of techniques including market intelligence gathering, test purchases, product testing and any other innovative solutions to deliver the outcomes.

OPSS follows the approach identified by WELMEC (European Cooperation in Legal Metrology) in market surveillance guides 5.2 ‘Market Surveillance (NAWI and MID)’ and 5.3 ‘Risk Assessment Guide for Market Surveillance: Weigh and Measuring Instruments’ to fulfil a programme of interventions in the market place.

Each market surveillance activity will be targeted at a sector, product type, manufacturer, distribution method or individual product following a risk assessment exercise.

When non-compliances are discovered the response will be both proportionate to the impact on consumers and the market place whilst remaining consistent with responses by other member states throughout Europe. OPSS participates in the activities of WELMEC working group 5 to ensure a high level of European consistency is achieved.

OPSS uses the appropriate sanction where necessary to ensure the outcomes identified in the directives are achieved. A full range of sanctions is available from administrative actions through to a full European safeguard action including product withdrawal from the market. Regulated entities that are affected by OPSS’ use of sanctions have a right of appeal.

Reporting issues with notified bodies

If you are an approved verifier, an approved manufacturer, a notified body or an inspector of weights and measures and have concerns about the way a piece of equipment was verified or conformity assessed by another organisation or the supporting processes, then read this guide to find out more details on what to include when reporting issues and email:
