Customer Complaints, Control of NCR & Corrective Action

ISO 9001:2015 Clause 10.2 · ISO 14001:2015 Clause 10.2 · ISO 45001:2018 Clause 10.2 — Nonconformity and corrective action; complaint handling

Procedure overview
A M Water Services treats every non-conformance — whether raised by a customer complaint, an internal observation, an audit finding, an inspection, an incident or a regulatory contact — through one consistent procedure that allocates a unique NCR number, investigates root cause, agrees corrective action with a named owner and target date, tracks completion to closure, verifies effectiveness, and feeds analysis into the wider improvement cycle. The HSQE Consultant maintains the Non Conformance Log as the single source of truth. Customer complaints route to the Directors for substantiation; substantiated complaints become NCRs and follow the same flow as any internally-raised non-conformance. Trends are reported at Management Review (SOP 6.4) and feed Continual Improvement (SOP 7.2). Records are retained per SOP 4.7.

NCR close-out timescales by category
Target close-out timescales from raise to verified-effective close on the NCR Log: Safety-critical (RIDDOR-reportable, near-miss with potential for serious harm, regulator finding) — immediate containment, full close-out target 7 working days, MD-monitored. Quality / customer complaint — acknowledgement to customer within 3 working days, full close-out target 30 calendar days. Process / minor non-conformance (audit finding, internal observation) — close-out target 30 calendar days; extension permitted with documented rationale on the log. Long-term improvement (systemic) — tracked under SOP 7.2 with the action plan timescale recorded on the log alongside the NCR. Any NCR open beyond target without recorded extension is escalated to the Directors at the next weekly compliance call.
