Introduction to the NHS complaints procedure in Wales

Covering the basics of the Welsh NHS and social care complaints procedure.

The NHS complaints procedure applies to all NHS bodies in Wales, as per the National Health Service (Concerns, Complaints and Redress Arrangements) (Wales) Regulations 2011.

The above applies to all dental settings providing NHS services, however general dental practitioners must also consider their requirements under Welsh GDS regulations.


The purpose of the complaints procedure is to address complainants' concerns in order to resolve complaints and identify changes that might be needed to improve the care provided.

Patients in Wales, or their representatives, can raise concerns about their NHS care within one year of the incident, or within one year of becoming aware of a problem. However, the DDU advise that you consider accepting complaints after this time so that they can be managed locally.

Your responsibilities

  • Principle 5 of the GDC's Standards for the Dental Team requires all dental settings to have a clear and effective complaint procedure.
  • NHS dental service providers, including independent contractors, must comply with the NHS regulations by having a patient complaint procedure available, that complies with the legislation.
  • All staff must have a good understanding of the complaints procedure and know how to handle and respond to complaints and concerns.
  • The service must have clear arrangements in place to provide leadership and a clear line of accountability for responding to complaints.
  • A responsible person - often a senior manager or practice principal - should ensure the service complies with the procedure. There must also be a complaints manager, who is accessible to the public.

Resolving complaints

The NHS Wales complaints procedure has two stages:

  1. local resolution
    1. you should acknowledge complaints within two working days
    2. you should Investigate and respond within 30 working days
  2. Public Services Ombudsman for Wales (PSOW).

Oral complaints that can be resolved satisfactorily within one working day do not fall within the regulations that govern the procedure, and although they need to be recorded, they are not included in the practice's annual report on complaints.

Disciplinary action

The complaints procedure does not have a disciplinary function, but a complaint can result in disciplinary action. Where disciplinary action is contemplated against a dental professional who is also the subject of a complaint, the two processes should be treated entirely separately.

Negligence claims

NHS regulations may require a complaint to be stopped if there is a claim for negligence. If you're a DDU member in this situation, contact us for advice.

Recording and reporting

The complaints manager should keep an up-to-date log of all complaints and how they were responded to. This should be recorded in a separate complaints file, not as part of patients' clinical records.

Practices must report annually on their complaints to their Local Health Board (LHB). It must contain the number of complaints received, how many were considered to be well-founded, and how many were referred to the Ombudsman.

Learning from complaints

All practices must have formal mechanisms in place to allow complaints to drive learning and improvement.

If there is a serious complaint, or a recurring theme in the subject matter of multiple complaints, then an investigation should be carried out. A report should include:

  • a summary of the subject matter of the complaint(s), excluding confidential information and confined to details of the nature of the complaint(s)
  • any matters of general importance arising from the complaints (such as lessons learned) or from the way in which they were handled
  • improvements to services made as a result of the complaint.
