Complaints: NiNAS recognises that on occasion it may be necessary for our clients, or those using accredited services, to raise a complaint with us. The following details the process to be followed:

Clients and users of accredited services: If you are complaining about a NiNAS accredited conformity assessment body, please ensure you have complained to them first, and that you have allowed them the opportunity to investigate and respond before escalating your complaint to NiNAS. Information on raising a complaint about an accredited body can be found here. Please read this information prior to submitting your complaint.

NiNAS accredited bodies: If you are a NiNAS client and wish to make a complaint, please we would encourage you in the first instance to discuss your concerns with the Director of Accreditation ( or our Quality Manager, , as it may be possible to resolve any concerns you have via that route. However, if this does not resolve the matter you can submit a complaint. Any complaint must be submitted in writing here on the website or email it to , and we ask that it includes copies of relevant communications where applicable.

Complaints will be logged and acknowledged within 5 working days of receipt and an investigating officer appointed to review and respond to the complaint. The investigating officer will normally be an individual who has not been involved directly in the activities to which the complaint relates. Timelines for completing the investigation will be communicated via the acknowledgement as these may vary dependent on the extent, complexity and severity of the issues detailed in the complaint. We do, however, aim to resolve most complaints within 3 working months of receipt.
