FCA Consumer Duty — SaaS Pricing Transparency
Price and Value outcome: price must represent fair value — not excessive relative to benefits provided.
Consumer Understanding: pricing must be clear, prominent, and not misleading — no hidden fees surfaced at checkout.
Renewal pricing: must clearly communicate when a promotional price ends and the renewal price takes effect.
Annual vs monthly pricing: both options must be clearly presented — not hiding the cheaper annual option.
FCA Consumer Duty applies to SaaS products offering regulated financial services (payment products, credit, insurance, investment). Consumer Duty pricing transparency requirements:
UK SaaS Pricing Page Best Practices
| Element | Best Practice | UK-Specific Consideration |
|---|---|---|
| Price display | Show GBP prominently — not USD for UK market | UK B2B buyers distrust USD pricing — shows lack of UK market focus |
| VAT visibility | Show +VAT or incl. VAT clearly | HMRC requirement: prices shown excl. VAT for B2B, incl. VAT for B2C |
| Annual vs monthly | Annual prominently displayed with savings calculation | Annual contracts reduce churn 40–60% — default to annual |
| Free trial | 14-day trial is UK standard | Consumer Rights Act cooling-off less relevant for B2B SaaS |
| Enterprise pricing | "Contact Sales" only for true enterprise (100+ seats) | Show starting price — transparency is UK competitive advantage |
| Payment methods | Card + GoCardless Direct Debit + BACS | Direct Debit: 40–50% of UK B2B prefer to pay by DD — offer it |
