Step 01

The Challenge

A UK financial services group wanted to launch a regulated Buy Now Pay Later (BNPL) product for UK retail partners — following the FCA's decision to bring BNPL into regulation under the Financial Services and Markets Act 2023. FCA CONC (Consumer Credit Act), FCA Consumer Duty PS22/9, FCA affordability assessment requirements for BNPL, ICO UK GDPR for credit data, Companies House verification, and AML (MLRs 2017) were mandatory. The platform needed to integrate with 85 retail partners via API. Budget: £140,000.

Step 02

Our Approach

FSMA 2023 regulated BNPL

interest-free deferred payment agreements are now regulated credit under the Consumer Credit Act.

Key FCA requirements

(1) affordability assessment (proportionate to BNPL credit risk —

FCA guidance

soft credit check minimum, income verification for larger amounts). (2) CONC pre-contract information: clear BNPL terms before checkout. (3) forbearance: customers in financial difficulty must be offered payment plans. (4)

Consumer Duty

value assessment (is BNPL fair value vs alternative finance?), consumer understanding (are BNPL terms understood before purchase?).

Retail Partner API Integration

  • 85 retail partners: headless BNPL checkout widget (React — drops into any retailer's checkout), BNPL REST API (partner backend integration — order creation, refund, cancellation), webhook events (payment received, late payment, full repayment).
  • OpenAPI 3.0 specification: published to retail partners as machine-readable API documentation (FCA COBS machine-readable disclosure).

Partner onboarding

Companies House verification, bank account verification (Creditsafe), and merchant agreement (DocuSign).

Soft credit check

Experian API (soft search — no credit file footprint, customer-consented).

Income estimation

open banking AISP (TrueLayer — 3 months income/expenditure) for purchases above £250.

Credit limit calculation

purchase history (repeat customers with good repayment get higher limits), Experian score, and income estimation.

Credit limit transparency

customer can see their BNPL limit and how it is calculated — FCA Consumer Duty Consumer Understanding.

FCA CONC

debt collection must be fair and not cause harm.

Late payment flow

Day 3 (SMS reminder — GOV.UK Notify), Day 7 (email reminder with payment link), Day 14 (formal arrears notice — Consumer Duty vulnerable customer assessment), Day 21 (payment plan offer — automatically generated based on outstanding balance and estimated income), Day 60 (default, credit file marker).

Vulnerable customer

if customer indicates financial difficulty at any stage, mandatory payment plan offer — no additional fees.

Step 03

The Results

FCA CONC compliance confirmed.

Platform live at 20 weeks, £132,000 — under budget. 85 retail partners onboarded in 10 weeks. 84,000 BNPL transactions in first 6 months.

Average transaction: £142.

Late payment rate: 4.2% (industry benchmark: 6.8% — affordability assessment materially reduces defaults).

Payment plan uptake: 68% of customers in arrears accepted payment plan (target: 60%).

FCA Consumer Duty review: confirmed compliant.

Retail partner NPS: 84.

Client Testimonial
4.2% late payment rate versus 6.8% industry benchmark — the affordability assessment works. 68% of customers in arrears accepted a payment plan — that is the Consumer Duty forbearance obligation met in practice, not just in policy. 85 retail partners onboarded in 10 weeks. FCA Consumer Duty confirmed compliant. The regulatory work was the foundation everything else is built on." — CEO, UK BNPL Provider (name withheld)
