Certs Reminder

Certificate due date calculator

Enter the certificate type and issue date to see the likely expiry date and a recommended booking window 4–8 weeks before. Then sign up free if you want email reminders instead of a calendar note.

Use this for planning only. Confirm the real expiry date on your document — especially for HMO licences and any certificate with a printed end date that differs from the usual cycle.

Certificate type

This calculator uses common UK validity periods for planning. It is not legal advice. Always verify the expiry printed on your certificate and any local licensing conditions.

FAQs

Is the calculated expiry always correct?

No. It uses common cycles (for example 12 months for Gas Safety, 10 years for an EPC). Your document may show a different end date. Always trust the printed certificate.

Why is there a 4–8 week booking window?

Engineers and assessors book up. Planning a few weeks early helps you renew before the certificate lapses.

Can I get email reminders instead?

Yes. Create a free Certs Reminder account, upload the certificate, confirm the dates, and we email you at 30, 7 and 1 day before expiry.

Does this store my dates?

No. The calculator only shows results in your browser session. Nothing is saved until you create an account and upload a certificate.
