Step 01

The Challenge

A UK FCA-authorised mortgage broker with 240 advisers and 8,400 active clients wanted to build a digital mortgage broker platform — replacing manual fact-finding (paper, Excel) with a digital client journey incorporating Open Banking affordability verification, automated sourcing (criteria matching across 90 lenders), and digital document submission. FCA MCOB (mortgage conduct of business), FCA Consumer Duty PS22/9, ICO UK GDPR for mortgage data, and FCA Suitability Assessment records were the requirements. Budget: £120,000.

Step 02

Our Approach

TrueLayer AISP

12-month bank statement analysis for income verification and expenditure categorisation.

Income verification

salary credits → employer verification (HMRC PAYE reference cross-check), rental income, dividend income, and benefits income identified.

Expenditure categorisation

committed (mortgage/rent, loans), basic (utilities, food), discretionary (entertainment, subscriptions), and irregular (annual costs).

Affordability calculation

lender-specific affordability model applied (each lender has different stress test — ONS expenditure benchmarks for declared vs undeclared expenditure).

Mortgage Criteria Sourcing Engine

90-lender criteria database: each lender's criteria (LTV limits, income multiples, property types, credit history requirements) stored as structured rules.

Criteria matching

client profile → filtered lender list → ranked by rate (APRC).

Integration with Twenty7Tec/Trigold criteria engine

real-time rate and criteria data.

Suitability filtering

  • products automatically filtered by FCA MCOB suitability (repayment type, term, rate type appropriate to client needs).
  • FCA MCOB Digital Fact-

Find and Suitability

MCOB 4.7

A Mortgage Illustrations

ESIS generated automatically from criteria match → adviser reviews before client presentation.

Suitability Report

digital suitability assessment (client objectives, needs, circumstances, product recommendation justification) — generated from structured fact-find data.

MCOB 11 Responsible Lending

affordability assessment documented and stored (FCA audit trail).

Digital signatures

client signs Mortgage Application Agreement (MAA) via DocuSign.

Lender document portals

90 different portals, 90 different document formats.

ClickMasters solution

  • document submission API layer abstraction — single submission from broker platform → correct format transformation → lender portal API (where available) or automated email (where no API).
  • Decision in Principle (DIP): automated DIP submission for supporting lenders (Nationwide, Halifax, Santander API).

DIP turnaround

automated DIP within 30 seconds for API-connected lenders (previously 2–3 days manual submission and wait).

Step 03

The Results

Platform live at 20 weeks, £112,000 — under budget.

Fact-find completion time: 2.8 hours45 minutes.

Affordability calculation: manual 4-hour exercise → automated 8 minutes.

DIP turnaround (API lenders): 23 days30 seconds.

MCOB suitability report: automated → 78% accepted without adviser amendment.

Consumer Duty value assessment: confirmed by FCA compliance review.

Adviser satisfaction: 4.6/5 (legacy paper process: 1.9/5).

Client Testimonial
30-second DIP versus 2–3 days. Adviser satisfaction from 1.9 to 4.6. Fact-find 2.8 hours to 45 minutes. 78% suitability reports accepted without amendment — the structured data generates better first drafts than manual writing. FCA Consumer Duty review confirmed compliant. The advisers genuinely celebrate using this platform." — Managing Director, UK Digital Mortgage Broker (name withheld)
