Step 01

The Challenge

A UK FinTech company launching a Buy Now Pay Later (BNPL) service (FCA Consumer Credit Act authorisation, FCA CONC regulated, no-interest 3-month instalment product for UK consumers) needed to build a compliant BNPL platform from scratch. FCA CONC (Consumer Credit sourcebook), Consumer Credit Act 1974, FCA Consumer Duty PS22/9, FCA PS21/3 (IBS -- payment initiation), FCA SCOR (Supervisory Formula Approach for consumer credit capital), AML MLRs 2017, ICO DPIA (credit decisioning profiling), CRA 2015 (Consumer Rights Act -- 14-day cancellation), UK GDPR, and Cyber Essentials Plus were mandatory. Budget GBP160,000.

Step 02

Our Approach

FCA CONC for BNPL

  • 1CONC 5.2A creditworthiness assessment (affordability check -- income vs expenditure, existing debt obligations -- ClickMasters integrates Open Banking TrueLayer for income verification + CRA (Credit Reference Agency -- Experian/Equifax) for existing debt),
  • 2CONC 4.2 Pre-Contract Information (SECCI -- Standard European Consumer Credit Information -- must be provided before credit agreement),
  • 3CONC 6.7 Arrears management (if customer misses payment -- forbearance policy, breathing space, StepChange referral),
  • 4CONC 3.3 Financial promotions (BNPL must not be promoted in a way that encourages over-indebtedness),
  • 5CONC 13 Cancellation rights (CCA 1974 Section 66A -- 14-day withdrawal right for BNPL, no penalty).

FCA Consumer Duty BNPL Design

FCA Consumer Duty for BNPL (2026 priority sector for FCA): (1) Product design outcome (BNPL product designed so customers who should not be offered credit are not offered it -- affordability check gate), (2) Price and value outcome (no fees charged to customer in good standing -- transparent fee structure), (3) Consumer understanding outcome (SECCI in plain English -- Flesch-Kincaid Grade Level 7 or below, confirmed in User Testing with representative sample), (4) Consumer support outcome (FCA DISP complaint response within 8 weeks, FOS referral information, breathing space signposting), (5) Vulnerable customers (FCA FG21/1 -- BNPL does not promote to known vulnerable customers, forbearance available from day 1 of arrears).

BNPL credit decisioning

  • 1Open Banking affordability (TrueLayer AISP -- customer shares bank data, income and expenditure extracted, disposable income calculated),
  • 2CRA credit check (Experian Bureau Score + existing BNPL debt flag),
  • 3decision engine (scorecard -- Open Banking + CRA + order value + merchant category),
  • 4ICO DPIA (automated credit decision = ICO Article 22 -- right to human review for rejected applications -- automated decision gateway requires human review option),
  • 5credit limit setting (based on scorecard -- initial limit GBP200-GBP1,000, increases earned by repayment behaviour). FCA CONC 5.2A: creditworthiness assessment must include information about existing debt -- CRA mandatory for responsible lending compliance.

FCA PS21/3 IBS

BNPL payment collection is an IBS.

Impact Tolerance

4-hour maximum downtime for repayment collection (customer payments cannot be lost -- Direct Debit mandate or GoCardless VRP).

Repayment infrastructure

  • 1GoCardless BACS Direct Debit (monthly repayment mandate -- predictable, low failure rate),
  • 2GoCardless VRP option (flexible repayment amount -- customer chooses to pay more),
  • 3payment failure workflow (GoCardless webhook on failure -- immediate customer notification, forbearance offered, StepChange referral),
  • 4arrears management (day 1, 7, 14, 28 contact steps -- FCA CONC 6.7),
  • 5debt sale prohibition (FCA CONC -- BNPL debt must not be sold to debt purchaser without customer consent).

PS21/3 quarterly chaos test

GoCardless API dependency failure test -- IBS recovery within 4 hours.

Step 03

The Results

FCA Consumer Credit authorisation obtained.

FCA Consumer Duty confirmed.

Platform live at 28 weeks, GBP148,000. 42,000 BNPL customers in year one.

Approval rate: 68.4% (FCA affordability gate: 31.6% declined).

Average order value: GBP284.

Repayment rate: 94.2% on time.

Arrears rate: 5.8% (industry average: 9.2%).

Flesch-Kincaid Grade Level 7.1 (SECCI).

FOS complaints: 2 (both found in ClickMasters favour).

ICO DPIA: filed. 42,000 customers.

Approval 68.4% (31.6% declined by affordability gate).

Repayment 94.2% on time.

Arrears 5.8% vs 9.2% industry.

SECCI Grade Level 7.1.

FOS 2 complaints both found in our favour.

ICO DPIA filed.

The affordability gate -- declining 31.6% of applicants -- is what makes this BNPL product a Consumer Duty success.

We could approve more customers.

But more approvals with worse repayment rates is not a good outcome for consumers.

Consumer Duty means designing products to succeed for the customers they serve, not maximising short-term approval rates. -- CEO, UK BNPL FinTech
