Bank vs Specialist Development Finance: Pros, Cons and When to Use Each
High street banks offer the cheapest rates. Specialist lenders offer speed and flexibility. Here is how to decide which route is right for your development.
The Two Markets for Development Finance
UK development finance broadly splits into two markets. High street banks (Lloyds, NatWest, HSBC, Barclays, Santander) offer the lowest rates but the most rigid criteria. Specialist lenders (Atelier, CrowdProperty, LendInvest, Maslow, and dozens more) charge more but move faster and accept deals that banks won’t touch.
Understanding which market your deal fits is the first decision you need to make. Get it wrong and you waste weeks on a bank application that was never going to be approved, or overpay with a specialist lender for a deal any bank would fund.
Expert Insight
Based on our experience arranging over £500M in property development finance, the right product choice depends on project timeline and scope. We consistently see developers save 15-25% on total finance costs by selecting the correct product from the outset rather than retrofitting a facility mid-project.
Bank Development Finance: What to Expect
High street banks typically offer development finance at 4-6% over base rate (currently equating to roughly 8-10% all-in), with arrangement fees of 1-1.5%. They will fund up to 60-65% LTGDV and require a minimum developer track record of 3-5 completed schemes.
The approval process involves a full credit committee review, which takes 6-12 weeks from application to first drawdown. Banks require detailed QS reports, full planning permission (not just outline), and evidence of pre-sales or lettings on larger schemes.
The advantage is cost: bank rates can be 2-4% per annum cheaper than specialist lenders. On a £10M facility over 18 months, that difference is £300,000-£600,000 in interest savings.
Specialist Development Finance: What to Expect
Specialist lenders offer rates from 6.5% per annum (typically 8-12% all-in with fees) and will fund up to 70% LTGDV, sometimes 75% for experienced developers. Track record requirements are more flexible: some will fund second or third projects, and most will consider the strength of the wider team (contractor, architect, project manager).
Speed is the headline advantage. Specialist lenders can issue terms within 48 hours, complete due diligence in 2-4 weeks, and have funds available within 4-6 weeks of application. Some can complete in as little as 2 weeks for straightforward schemes.
They are also more flexible on scheme type. Permitted development conversions, unusual planning conditions, modular construction, mixed-use with a commercial element above 30% - specialists regularly fund deals that fall outside bank policy.
Side-by-Side Comparison
Rates: Banks from 4-6% over base rate. Specialists from 6.5% p.a. fixed. On current base rates, the gap is roughly 2-4% per annum.
LTV/LTGDV: Banks max at 60-65% LTGDV. Specialists go to 70-75% LTGDV. The higher gearing from specialists means less equity required.
Speed: Banks take 6-12 weeks. Specialists take 2-6 weeks. If you need to move fast (site under offer, planning expiring), a specialist is the only realistic option.
Track record: Banks want 3-5 completed schemes. Specialists may accept 1-2 completions, or a strong team with a less experienced lead developer.
Flexibility: Banks follow rigid policy on scheme type, location, and unit mix. Specialists take a commercial view on each deal and can often find ways to make unusual schemes work.
Ongoing relationship: A bank facility comes with a relationship manager and access to other banking products (hedging, trade finance, deposits). Specialists are transactional - you borrow, you repay, the relationship ends.
| Feature | High-Street Bank | Specialist Lender |
|---|---|---|
| Rate | 5.5-7.5% p.a. | 7-12% p.a. |
| Max LTGDV | 55-60% | 65-75% |
| Speed | 8-16 weeks | 2-6 weeks |
| Experience required | 3+ completed schemes | First-time considered |
| Min facility | £1M+ | From £250K |
| Flexibility | Rigid criteria | Case-by-case assessment |
When to Use a Bank
Use a bank when you have a strong track record (5+ schemes), the project is straightforward (residential, full planning, established location), and timeline is not the main constraint. The interest savings on larger facilities (£5M+) can be substantial.
Banks are also the right choice if you want to build a long-term lending relationship. Repeat borrowers often negotiate improved terms, faster approvals on subsequent deals, and access to higher gearing as trust builds.
Best for: established developers with a pipeline of 3+ projects, schemes above £5M GDV in prime locations, projects where planning and pre-sales are already in place.
When to Use a Specialist Lender
Use a specialist when speed matters, when your track record is limited, when the scheme is unusual, or when you need higher gearing than a bank will offer. The premium you pay in interest is often offset by the cost of delay or the opportunity cost of missing a site acquisition.
Specialists are essential for: permitted development conversions, schemes below £1M (most banks have minimum facility sizes), sites purchased at auction with tight completion deadlines, and projects in secondary or tertiary locations that fall outside bank catchment areas.
Many experienced developers use specialists for early-stage or opportunistic deals where speed is critical, then refinance to a bank facility for their core pipeline projects. Construction Capital can help you structure either route.
For developers exploring other funding options, we also arrange commercial mortgages and bridging loans.

When comparing property finance options, consider the regulatory framework: the Financial Conduct Authority (FCA) regulates certain types of lending, while RICS standards govern valuations across all product types. HM Land Registry registration applies to all secured lending, and Building Regulations compliance affects the exit valuation regardless of which finance product you use.

Frequently Asked Questions
Are bank development loans always cheaper than specialist lenders?
Yes in terms of headline interest rates (typically 2-4% cheaper per annum). However, the slower approval process can cost more in opportunity terms if you miss a site purchase. Factor in total cost including delays, not just the interest rate.
Can I get development finance from a bank as a first-time developer?
It is very difficult. Most high street banks require evidence of 3-5 completed developments. First-time developers should approach specialist lenders who assess the whole team, not just the lead developer's personal track record.
How do I switch from a specialist lender to a bank?
Complete 2-3 schemes successfully with specialist funding, building a demonstrable track record of delivery on time and on budget. Then approach banks with your completed portfolio. A broker like Construction Capital can make introductions at the right time.
