If you would like to verify a person's certificate or qualification parchment, this can be done online with self-service verifications platform: NEBOSH Verifications.
If the certificate was issued before 1991, if the online platform cannot verify the certificate with the information you have provided, or if you need a formal verification for emigration, visa or other legal purposes you will need to contact us directly through our Verification Policy.
