The IASME assessment fee is the small part of Cyber Essentials. This calculator estimates the true first-year cost, fee plus the remediation you actually pay to pass, and flags the April 2026 rules that fail you on the spot if you miss them.

Tick what you already have fully in place MFA enabled on every cloud service that offers it, for all users Business-grade endpoint protection on every device (not consumer antivirus) High-risk and critical updates applied within 14 days, across OS, firmware and apps Admin rights restricted to named accounts used only for admin tasks We will use a consultant for a gap analysis or pre-assessment

Figures exclude VAT unless stated. IASME sets the basic assessment fee centrally; Plus is quoted per body and scales with device count, so the Plus figure here is an indicative midpoint.
