The UK development finance platform landscape in 2026
The way developers, brokers, and lenders connect has changed dramatically. A new generation of technology platforms has emerged alongside traditional brokers, each taking a different approach to solving the same problem: getting development deals funded faster and more efficiently.
This guide compares every major option available in the UK market, with honest assessments of strengths, limitations, and who each platform is best suited for.

3. Broka — sourcing + case management
What it does: Broka is a commercial loan sourcing platform that matches broker cases to lender products using criteria-based search across 243 specialist lenders and 1,000 financial products.

Limitations: Broker-only — no borrower access. No credit paper generation. Hidden pricing. No document extraction. Relatively new (2024–2025).
4. DealLocker — investment marketplace
What it does: DealLocker is a real estate investment marketplace that connects property developers with private investors for equity joint ventures and second charge (mezzanine) financing. It is not a development finance sourcing tool — it focuses on connecting capital with deals rather than matching borrowers to senior lenders.
Key features:
- Marketplace connecting deal providers with private investors and family offices
- CRM and portfolio management (contacts, documents, KYC tracking)
- AI deal summaries for investor review
- Electronic NDA system for deal confidentiality
- Capital calculator for equity/profit-sharing modelling
- Covers equity JVs and second charge financing
Pricing: Premium membership from £70/month per user. Enterprise CRM at £350/month per company. Plus transaction fees of 1–3.5% on completed deals depending on deal type.
Best for: Developers who specifically need equity co-investors or mezzanine finance from private capital. Investors looking for deal flow in CRE equity and second charge.
Limitations: Monthly subscription required before accessing any deals. Does not source senior development finance — only equity and mezzanine. Not FCA regulated. Very new (incorporated April 2024) with no independent reviews. Transaction fees of 1–3.5% charged on top of the subscription. No credit paper generation or document extraction.
5. Knowledge Bank — criteria search

Best for: Mortgage brokers who work across all lending types and need a comprehensive criteria search tool. Brokers who need FCA Evidence of Research compliance.
Limitations: Criteria search only — no rates, no deal modelling, no applications. No borrower-facing element. No credit paper generation. Less depth on development finance than specialist platforms.
6. Finbri — specialist broker
What it does: Specialist bridging loan and development finance broker with a strong digital presence. Not a technology platform — a traditional broker with excellent content marketing.
Key features:
- Loans from £26k to £250M, terms 1–36 months
- Fast completion: 3 days (up to £300k), 7 days (up to £750k), 14 days (up to £250M)

Pricing: Broker fee of 0.5–1% of loan amount, plus lender arrangement fees.
Best for: Borrowers who prefer a personal, hands-on broker relationship. Complex deals that need bespoke negotiation. Those who found Finbri through search and want a straightforward enquiry process.
Limitations: Traditional broker model — you rely on one firm's network and judgement. Broker fee on top of lender fees. No technology platform or self-serve option. Speed depends on the broker's workload.
7. LendInvest — direct lender
What it does: Major UK property finance lender offering bridging loans, development finance, and buy-to-let mortgages through an intermediary portal.
Key features:
- Proprietary intermediary portal for brokers
- Product transitions: bridge → development finance → development exit with same lender
- Indicative terms in 24 hours, credit decisions in 48 hours
- In-house chartered building surveyor
- Well-capitalised with institutional backing
Pricing: Rates from 0.80%/month. Intermediary-only — must submit through a broker.
Best for: Deals that suit LendInvest's criteria specifically. Borrowers who want product transition capability (one lender for the entire project lifecycle). Brokers who already have a LendInvest relationship.
Limitations: Single lender — you only see LendInvest's products. Intermediary-only. Not a comparison tool or marketplace. Higher minimum loan (£75k).
8. Octane Capital — specialist bridging lender
What it does: Specialist bridging lender based in London, focused on bespoke bridging, refurbishment, and development exit finance.
Key features:
- Loans £175k to £15M, terms up to 24 months
- Bespoke pricing — every deal priced to risk

- Accepts non-UK residents, foreign nationals, offshore structures, adverse credit
- Direct access to decision-makers (BDMs and credit managers)
Pricing: Rates from 0.73%/month. No exit fees. Broker-submitted only.
Best for: Complex, non-standard cases that high-street lenders won't touch. Borrowers with adverse credit, offshore structures, or unusual circumstances.
Limitations: Single lender. Higher minimum (£175k). Bespoke pricing means less upfront transparency. Bridging focus — not development finance.
How to choose the right platform
The right choice depends on who you are and what you need:
- If you're a developer who wants to submit directly: Assesr is the only platform that lets you do this without a broker, with AI credit papers and 0.5% pricing.
- If you're a broker who wants to compare rates quickly: Brickflow offers the best rate comparison and deal modelling tools.
- If you're a broker with niche asset classes: Broka has the broadest specialist lender panel at 243 lenders.
- If you're a broker across all mortgage types: Knowledge Bank covers 8 lending areas at just £20/month with FCA compliance tools.
- If you need equity co-investors or mezzanine: DealLocker connects you with private capital — but be aware of the £70/month subscription and 1–3.5% transaction fees on top.
- If you want a personal broker relationship: Finbri or a local specialist broker offers hands-on service.
- If you want the credit paper automated: Assesr is the only option. No other platform generates credit papers.
- If you want to pay nothing until the deal completes: Assesr's pay-on-success model is unique among the platforms.
The bottom line
The UK development finance market now has genuine technology options beyond the traditional broker model. Each platform has carved out a different niche: Brickflow in rate comparison, Broka in lender breadth, Knowledge Bank in criteria search across all mortgage types, and DealLocker in connecting developers with private equity investors.
Assesr occupies a unique position as the only platform that generates the actual credit paper — the document that gets deals approved. Combined with direct borrower access, pay-on-success pricing, and AI-powered document extraction, it represents the most comprehensive end-to-end solution for UK development finance.
