How does CertNudge calculate the expiry date?
Supported Certificate Types & Validity Rules
CertNudge uses the issue date plus the standard renewal period to suggest an expiry date - but you always have full control to adjust it before saving.
How It Works
- Select a certificate type (e.g. Gas Safety)
- Enter the Issue Date from your document
- The form will auto-fill the Expiry Date by adding the default interval (e.g. +1 year for Gas, +5 years for EICR)
- You can manually adjust the Expiry Date if needed
Example Scenarios
?? Example 1: Gas Safety Certificate
Issue Date: 10 Jan 2025
Default Interval: 12 months
Suggested Expiry: 10 Jan 2026
?? Example 2: Renewed Early
Previous expiry: May 2025
New Issue Date: March 2025
You can manually set the expiry to May 2026 to maintain the annual cycle.
Always Double-Check
Expiry dates may differ based on how your certificate was issued or renewed. We recommend checking the original document carefully before saving — especially if it was renewed early or has a custom validity.
The correct Issue and Expiry Dates are ultimately your responsibility. CertNudge provides smart defaults, but it's always best to verify them against the certificate itself.
