The verdict in three sentences
A community lender in London with 25,000 customers that underwrites on paper and email in 7 days loses part of its applicants to faster competitors and has poor visibility on its portfolio at risk. A custom KYC, underwriting and scoring module costs, as a 2026 ballpark, about 47,000 to 112,000 GBP (55,000 to 130,000 EUR), including the connection to the core lending system. Success is measured twice: a time to decision cut to 1 or 2 days and a PAR 30 kept below 5 %.
Why paper costs more than it seems
The paper file moves between the loan officer, the branch manager, the credit committee and operations. Each step adds a day, and KYC documents (ID, proof of address, bank statements, guarantors) go missing or arrive incomplete. Yet FCA rules on affordability checks, anti-money laundering and Consumer Duty require a complete audit trail for every loan.
| 2026 indicator | Paper underwriting | Digital underwriting |
|---|---|---|
| Average time to decision | 7 days | 1 to 2 days |
| Files underwritten per officer per month | 30 to 40 | 60 to 75 |
| Applicant drop-off rate | 12 to 18 % | 4 to 7 % |
| Incomplete KYC files at committee | 20 to 30 % | under 5 % (mandatory fields) |
| Paper and handling cost per file | 4 to 7 GBP | under 1 GBP |
| Regulatory reporting preparation | 3 to 5 days a month | a few hours |
| PAR 30 visibility | monthly, delayed | daily, per officer and per branch |
These values are estimates observed at lenders with 10,000 to 50,000 customers. They are meant to size the project.
Module scope and budget
The module does not replace the core lending system, which remains the accounting reference for loans. It handles everything before disbursement: KYC capture, underwriting, scoring, committee decision, then pushing the approved loan to the core system and disbursing by bank transfer.
| Component | Key function | Estimated 2026 budget (GBP) |
|---|---|---|
| Digital KYC onboarding | ID capture, selfie match, address checks, open banking consent | 9,300 to 20,400 |
| Underwriting workflow and committee | Approval routing, delegated authority, audit trail | 10,200 to 24,100 |
| Scoring | Business rules first, then a model on repayment history | 8,300 to 22,200 |
| Core lending and payments connection | Loan creation, disbursement, repayment schedule | 11,100 to 25,900 |
| Regulatory reporting and PAR tracking | Reporting tables, arrears alerts | 7,400 to 18,500 |
| Total | Full module | 46,300 to 111,100 |
A mobile-friendly flow is essential: most applicants now apply from a phone, and field officers visiting small businesses need offline capture. Allow 5 to 8 months for a full rollout, with a pilot branch or product line for 6 to 8 weeks.
Measuring time to decision from day one
The software must timestamp each step: application, complete KYC, affordability check, committee, decision, disbursement. Application-to-disbursement time becomes the KPI published weekly, per branch. Paired with PAR 30 per officer, it confirms that speed is not bought with worse risk.

Priya, COO of a community lender with 25,000 customers in London, receives 9,000 loan applications a year. With 15 % drop-off due to delays, she loses 1,350 applications. Bringing that rate to 5 % recovers 900 loans a year. With an average loan of 3,500 GBP and a 12 % net interest margin, the gain reaches 378,000 GBP a year. Meanwhile, scoring and alerts bring PAR 30 from 7 % to 5 % on a 25 million GBP portfolio: 500,000 GBP less at risk, or about 150,000 GBP of losses and provisions avoided assuming a 30 % loss rate. Finally, higher productivity avoids hiring 4 underwriters, about 152,000 GBP a year. The total gain of about 680,000 GBP a year pays back a module at 80,000 GBP in under 2 months. This scenario is illustrative and must be recalibrated with your own data.
FAQ
Do we need to replace our core lending system to digitize origination?
No, in most cases the module connects to the existing core system via API or file exchange. That connection often represents 20 to 25 % of the total budget.
Is automated scoring reliable from the start?
V1 relies on business rules approved by the credit team, then a statistical model is trained after 12 to 18 months of digital history. The committee keeps the final say on files above a threshold, for example 15,000 GBP.
How do we meet FCA expectations?
The module keeps a timestamped audit trail of every decision, produces reporting tables and applies anti-money laundering and affordability controls. Involving compliance from the scoping phase avoids costly rework.
Can field officers work offline?
Yes, the tablet app stores files offline and syncs as soon as the network returns. This helps reach a 1 to 2 day decision time for applicants met on site.
What rollout timeline should we plan?
Allow 5 to 8 months in total: 3 to 4 months of development, a 6 to 8 week pilot, then rollout in waves of 2 to 3 branches or product lines.
