CertMinder tracks every compliance certificate across your rental portfolio: gas safety, EICR, EPC, PAT, HMO licences, fire safety, all in one dashboard. Automated reminders fire before anything expires, so nothing slips through. One click generates an audit-ready compliance pack for councils or lenders. Built by a landlord tired of chasing expiry dates across spreadsheets and email. Free plan available, paid from £25/month.
