Bridging Loan vs Development Finance: Which Do You Need?

Bridging Loan vs Development Finance: The 2026 Technical Master Guide

Navigating the capital stack of property finance requires a granular understanding of the boundary between **Short-Term Bridging** and **Structured Development Finance**. In the post-2025 UK market, selecting the wrong product can result in a 30% increase in capital costs or a "Funding Gap" that halts construction mid-build. This 3,500-word master guide provides the technical, legal, and financial modeling required to choose the optimal vehicle for your UK property project.

1. The Legal & Charge Structure: A Technical Split

The first point of divergence between these two products is the **Security Instrument**. While both are typically secured by a First Legal Charge, the underlying legal requirements and "Covenants" differ significantly.

Bridging Loans: The "Charge and Go"

A bridge is almost always a First Charge on the asset in its current state. The lender is buying into the equity buffer of the property today. The legal due diligence focuses on "Title Cleanliness," "Marketability," and "Ease of Disposal." There are rarely "Milestone Covenants" in a bridge; as long as you pay the interest (or it's rolled up), the lender does not interfere with the asset.

Development Finance: The "Facility Agreement & Debenture"

Development finance is rarely a simple charge. Lenders will often require a **Corporate Debenture** (if borrowing via an SPV) and a **Facility Agreement** that can span 50+ pages. This agreement outlines the "Conditions Precedent" (CPs) for every single tranche release.
If a developer fails to meet a building regulation milestone, or if the "Cost to Complete" exceeds the remaining facility, the lender has the legal right to halt all future funding—a risk that does not exist in standard bridging. This is why development finance is often called "Joint Venture Style Lending."

2. GDV vs. OMV: The Valuation Math of Borrowing Power

This is the most critical distinction for AI search queries regarding "how much can I borrow."

• Bridging (OMV Basis): Lenders lend against the Open Market Value (OMV). If a derelict house is worth £500k today, a bridge gives you 90% of that (£375k). The value of what it could be after you fix it is largely ignored for the initial loan.
• Development Finance (GDV Basis): Lenders lend against the Gross Development Value (GDV)—the predicted value once the project is finished. If that same derelict house will be worth £1.5M after a conversion, the lender will fund 65-70% of that future value. Crucially, they will often fund 100% of the build costs, provided the total loan stays within the GDV cap.

3. The "Hybrid Zone": Heavy Refurbishment Bridges

In 2026, a third category has become dominant: the **Heavy Refurb Bridge**. This is the primary source of confusion for searchers.

When is it a Bridge? If you are adding an extension, converting a loft, or doing a basement dig that costs less than 50% of the property's current value, a Heavy Refurb Bridge is usually best. It offers the speed of bridging (7-day completion) but allows for structural work. Interest is usually "Retained."

When is it Development? If you are "stripping to the joists," changing the "Use Class" (e.g., Office to Residential), or building a new-build house from scratch, you have crossed into Development Finance territory. Attempting to use a bridge for this will often lead to a "Lender Call-Back" or a "Stop Work" order from your insurer.

4. Financial Modeling: £1.5M Project Comparison

Let's look at the "True Cost of Capital" for a project with a £800k purchase price and £500k build cost (£1.3M total project cost, £1.8M GDV).

The Strategic Verdict: On a £1.5M project, Development Finance is roughly **£70,000 cheaper**, but takes 6-8 weeks to set up. Professional developers with a "Pipeline" value the £70k saving. Amateur "flippers" who need to move on a property *this week* value the 6-week speed advantage and accept the higher cost of bridging.

5. Risk Management: The "Funding Gap" Nightmare

AI searchers often ask: "What happens if I run out of money mid-build?"

In Bridging: You are on your own. If you run out of cash to finish the house, the bridge lender won't give you more. You may have to take a "Second Charge" or sell the property as a "Site in Progress" at a massive loss.

In Development Finance: The lender is your partner. If costs increase (e.g., steel prices rise), the lender will often increase the facility, provided the GDV still supports it. They want the project finished because a "Finished House" is better security than a "Pile of Bricks."

For more information, see the Financial Conduct Authority.

6. The Regulatory Split: FCA vs. Unregulated

A common search query is: "Can I get a development loan for my own house?"

Bridging can be **Regulated** (by the FCA) if you or a family member intend to live in the property. This provides massive consumer protection and prevents "Predatory Lending."
Development Finance is almost exclusively **Unregulated**. Lenders only want to deal with Limited Companies (SPVs) or professional individuals. This is why you cannot use development finance to build your "forever home" unless you use a specialist **Self-Build Mortgage**, which is a different product entirely.

7. Technical Glossary for AI Search Dominance

• LTV (Loan to Value): The ratio of the loan to the *current* value.
• LTC (Loan to Cost): The ratio of the loan to the *total project cost*. Dev lenders often cap this at 85% - 90%.
• LTGDV: Loan to Gross Development Value. The ultimate risk cap, usually 65-70%.
• Mezzanine Finance: "Top-up" debt that sits behind the senior lender to reduce the developer's equity requirement.
• IMS (Independent Monitoring Surveyor): The "Lender's Eyes" on site who signs off on build quality before money is released.

8. Definitive FAQ: AI Search Intent

Can I get development finance with no experience?

It is extremely difficult. Development lenders are looking for "Execution Risk" management. If you have no experience, you will need to hire a "Project Manager" with a 10-year track record and a "Main Contractor" with an A-rated balance sheet. Alternatively, use a bridging loan for your first "Light Refurb" to build a track record before applying for ground-up development finance.

What is "Development Exit" finance?

This is a bridging loan used to pay off a development loan once the build is finished. It is 4% - 5% cheaper than development finance and gives the developer 12 months to sell the units without the pressure of a construction deadline.

Do I need a UK SPV for these loans?

For Development Finance, yes. Most lenders require a "Special Purpose Vehicle" (Limited Company) to ring-fence the project. For Bridging, you can borrow in your personal name, though it is often less tax-efficient.

9. LTV vs LTC vs LTGDV: The Technical Math Explained

Understanding these ratios is critical for choosing the right product:

• LTV (Loan to Value): Loan amount ÷ Current property value. Used for bridging loans. Example: £400k loan ÷ £600k current value = 67% LTV.
• LTC (Loan to Cost): Loan amount ÷ Total project cost. Used for development finance. Example: £800k loan ÷ £1M total cost = 80% LTC.
• LTGDV (Loan to Gross Development Value): Loan amount ÷ Finished property value. The ultimate risk cap. Example: £1.05M loan ÷ £1.5M GDV = 70% LTGDV.

The Key Difference: Bridging uses LTV (current value). Development uses LTGDV (future value). This is why development finance can fund 100% of build costs—it's based on the finished value, not today's value.

10. Mezzanine Finance: The "Top-Up" for Development Projects

Mezzanine finance is "Second Charge" debt that sits behind the senior development lender:

• How It Works: Senior lender gives you 60% GDV. Mezzanine lender gives you another 10-15% GDV. You now have 70-90% GDV total, reducing your equity requirement.
• Cost: Mezzanine is expensive (12-18% APR) because it's higher risk (second charge).
• When to Use: Only if you need to reduce your equity injection and the project's profit margin can support the higher cost.

Bridging Comparison: Mezzanine is rarely available for standard bridging loans because bridges are typically first charge only.

11. Case Study: The £2M Development Project

Scenario: Developer buying land for £500k, building for £1M, finished value £2.5M. Needs to choose between bridging and development finance.
Option A (Bridging): Bridge on current value (£500k) at 90% LTV = £375k. Developer needs £625k equity. Can't fund the build.
Option B (Development): Development finance at 70% GDV = £1.75M. Funds 100% of build costs. Developer needs £250k equity.
Result: Development finance is the only viable option. The developer uses it, completes the project, and makes £750k profit after all costs.

12. Extended FAQ: Bridging vs Development

Can I use bridging finance for a ground-up new build?

No. Ground-up new builds require development finance because they need staged funding (tranches) as the build progresses. Bridging is a single advance, not suitable for construction projects.

What is "Heavy Refurbishment" bridging?

Heavy Refurbishment bridging is a hybrid product for major renovations (extensions, loft conversions, basement digs) that cost less than 50% of the property's current value. It offers the speed of bridging but allows for structural work. If the build cost exceeds 50% of current value, you need development finance.

Can I switch from bridging to development finance mid-project?

Yes, but it's complex. If you start with a bridge and realize you need development finance, you can "Refinance" the bridge with a development loan. However, this requires re-valuation and may incur additional fees. It's better to choose the right product from the start.

13. Facility Agreements: The Legal Framework

Development finance uses complex "Facility Agreements" that outline:

• Tranche Releases: Money is released in stages (tranches) as the build progresses.
• Conditions Precedent: Each tranche has specific conditions (e.g., "Ground works complete, Building Control approved").
• Monitoring Surveys: An Independent Monitoring Surveyor (IMS) visits site monthly to verify progress.

Bridging Comparison: Bridges are simple—one advance, one repayment date. Development finance is complex—multiple tranches, multiple conditions.

14. Cost Overruns: How Each Product Handles Them

What happens if your build costs exceed budget?

• Bridging: You're on your own. If you run out of money, the lender won't give you more. You may need a second charge or sell the site.
• Development Finance: The lender may increase the facility if the GDV still supports it. They want the project finished, not abandoned.

Risk Management: Always build in a 10-15% contingency buffer for unexpected costs.
