Trust and source context
GradeCheck is an independent CIDB contractor verification and research platform for South Africa.
Contractor records are sourced from the CIDB Register of Contractors and presented with verification links, registration status, grading history, and capture timestamps.
GradeCheck is not affiliated with the Construction Industry Development Board. Final contractor confirmation should always be completed against the official CIDB source.
