Approved Supplier Self-Assessment Register

External providers evaluated against the AMWS Supplier Self-Assessment criteria — ISO 9001 Cl. 8.4 (control of externally provided products and services), ISO 14001 / ISO 45001 Cl. 8.1 (operational control).

How this register works
AMWS operates a supplier self-assessment approach proportionate to the scale of a 20-person water-services contractor. The supplier confirms an 8-point criteria checklist annually; AMWS verifies the supplier's public profile (Companies House status, visible accreditations, sector positioning) and rates the relationship by ongoing performance. Active suppliers are reviewed annually by Leanne Mason; inactive accounts are retained but flagged. This list complements APP_19 (this document) and replaces the previous per-supplier SAR markdown set as the controlled register.
