How do I complain about NHS treatment?

Contact the practice or hospital's complaints team first. If unresolved, escalate to the Parliamentary and Health Service Ombudsman (PHSO). You must complain within 12 months of the incident.

Can I complain about private dental treatment?

Yes — contact the Dental Complaints Service (DCS) within 12 months. They handle complaints about private dental care and can arrange refunds, remedial treatment, or apologies.

When should I report to a regulatory body?

Report to the CQC if a care provider is unsafe, the GMC for concerns about doctors, or the GDC for concerns about dentists. These bodies can investigate and take regulatory action.
