UK cyber insurance premiums rose 50-200% across 2022-2024 as ransomware claims escalated. Cyber Essentials Plus increasingly attracts material discount — typically 10-25% off premium — and in some cases is now a precondition for coverage. This is the practical ROI maths.
The market dynamic
Most UK SII (Solicitors' Indemnity Insurance) markets, professional indemnity insurers, and cyber-specific insurers now treat CE+ as a baseline.
For mid-market UK organisations: CE+ readiness work (typically £8-25k) pays back in 1-2 years on insurance premium reduction alone.
Increasingly, organisations WITHOUT CE+ are quoted higher premiums or refused coverage entirely.
Typical discount maths
£25k/year cyber premium → 15% CE+ discount → £3,750/year saving → 2.7-year payback on £10k CE+ readiness investment.
£100k/year premium (mid-market FS or legal) → 20% CE+ discount → £20k/year saving → 6-month payback on £12k CE+ readiness.
Larger orgs see steeper absolute savings; payback gets shorter at scale.
What CE+ doesn't do
CE+ is a baseline, not a ceiling. Organisations with material claim history or specific risk profile may still face premium loading.
CE+ doesn't replace ISO 27001 for organisations in regulated industries (FS, healthcare). Both can stack.
CE+ is annual — let it lapse and the discount + coverage gain disappears.
