The verdict in three sentences
A microfinance lender in London, such as a community development finance institution with several hubs and thousands of borrowers, should budget GBP 22,000 to 45,000 (about EUR 25,000 to 52,000) for a site that presents its products and receives loan pre-applications from small businesses. The value lies in the connection to the loan management system and a short mobile journey, since most applicants arrive on a smartphone. Allow 3 to 4 months and a review of every page against the FCA rules on financial promotions.
What the site must do for a microlender
The typical applicant is a market trader in Peckham, a food producer in Tottenham or a sole trader turned down by a high street bank. They want to know which loan fits, how much they can borrow, which documents to prepare and where to meet an adviser. The site therefore needs clear product pages (start-up loan, working capital, equipment, community enterprise), a simple calculator and a pre-application form of no more than 3 screens.
The pre-application does not replace underwriting: it creates a record in the loan management system, assigns the applicant to the right hub and triggers a call from a loan officer within 48 hours.
| Module | Content | 2026 budget (GBP) |
|---|---|---|
| Discovery and mobile UX | Applicant journey, 12 to 18 templates, mobile tests | 2,200 to 3,900 |
| Design and web guidelines | Mockups, product icons | 2,600 to 4,700 |
| Product pages and calculator | Start-up, working capital, equipment, savings | 3,000 to 6,000 |
| Pre-application form | 3 screens, uploads, consent | 3,500 to 7,000 |
| Loan system integration | API or secure export to the loan management system | 5,200 to 13,000 |
| Hub locator | Map of hubs, opening hours, phone numbers | 1,300 to 2,600 |
| Security, QA, launch | HTTPS, backups, light penetration testing | 3,900 to 7,800 |
The integration line varies most: if your software exposes a documented API, stay at the low end. If a connector or file exports are needed, plan for the high end.
Compliance, transparency and security
A regulated lender must show clear terms: representative APR, fees, term, security required. Under the FCA financial promotion rules and the Consumer Duty, every promotion must be fair, clear and not misleading, with a representative example where required. The site never promises approval: it talks about a pre-application subject to assessment. Data collected (ID, income, trading history) falls under UK GDPR and must be stored and transmitted encrypted.
| Requirement | Implementation on the site | Estimated effort |
|---|---|---|
| Transparent terms | Rate and fee table per product | 2 to 3 days |
| « Subject to assessment » notice | On every calculator and form | 0.5 day |
| Personal data consent | Explicit checkbox, purposes, retention period | 1 day |
| Encryption | HTTPS, encrypted attachments at rest | 2 to 4 days |
| Access log | Traceability of file access | 2 to 3 days |
| Backups | Daily, 30-day retention | Included in hosting |
Add a complaints page with handling times and a link to the Financial Ombudsman Service: it signals seriousness to applicants and the regulator.
Timeline and running costs
Allow 3 to 4 months: 3 weeks of discovery with operations and IT, 4 weeks of design, 6 to 8 weeks of development and integration, 2 to 3 weeks of QA with two pilot hubs. Secure hosting and maintenance cost GBP 350 to 800 per month. Also plan a WhatsApp Business line to answer questions before the pre-application.

Grace, chief executive of a London microlender with 4 hubs, invests GBP 33,000. After 4 months, the site receives 420 pre-applications a month, 30 % of which are complete and eligible, or 126 files. With a 60 % approval rate she grants 75 extra loans a month at GBP 7,000 on average: GBP 525,000 of new monthly lending. Loan officers save about 25 minutes per file because documents arrive before the meeting, close to 50 hours a month across the team.
FAQ
Can loans be approved fully online?
Some lenders do, but most community lenders keep an adviser conversation. The online pre-application still cuts average decision time from 10 to 5 working days.
Does the site need FCA sign-off on every page?
Financial promotions must be approved internally by a competent person before publication. Budget 1 to 2 days of compliance review per product page.
Should the site support other languages?
For London communities, adding key pages in 2 or 3 languages such as Polish, Somali or Bengali costs GBP 1,700 to 3,500 and widens reach.
Can repayments be made through the site?
Yes, via Open Banking or card payments: allow GBP 4,300 to 8,600 extra with automatic reconciliation in the loan system.
What pre-application volume should we expect?
For a lender with several thousand borrowers, 300 to 500 monthly pre-applications is a realistic 2026 order of magnitude after 3 to 4 months.
