What Is Commercial Bridging Finance?

**Commercial bridging finance** is a short-term secured loan used to fund commercial property transactions when speed, flexibility or circumstances make traditional mortgage lending unsuitable. Bridging loans typically last from 1 to 24 months and are designed to be repaid quickly through a defined **exit strategy** such as a property sale, refinance or business event.

At **Commercial Mortgages Broker**, we arrange commercial bridging facilities for businesses, investors and developers across the UK. This guide explains how commercial bridging works, when it makes sense and how it compares to longer-term finance.

How Commercial Bridging Finance Works

The fundamental principle of bridging finance is straightforward: a lender provides short-term funds secured against property, and the borrower repays the loan within the agreed term using a pre-planned exit strategy.

The Process

  1. Application: You provide details of the property, the purpose of the loan and your exit strategy
  2. Valuation: The lender arranges a professional valuation of the security property
  3. Legal due diligence: Solicitors handle title checks and legal documentation
  4. Funds released: Once approved, funds can be released in as little as 3-7 days for straightforward cases
  5. Loan term: You hold the facility for the agreed period (typically 3-18 months)
  6. Exit: You repay the loan via your planned exit strategy

Speed of Execution

The defining advantage of [bridging finance](/services/commercial-bridging) over traditional [commercial mortgages](/services/commercial-mortgages) is speed. While a commercial mortgage typically takes 8-16 weeks to complete, bridging finance can be arranged in:

  • Emergency cases: 3-5 working days
  • Standard cases: 1-3 weeks
  • Complex cases: 3-4 weeks

This speed makes bridging finance essential for time-sensitive transactions.

When to Use Commercial Bridging Finance

Commercial bridging is appropriate in a wide range of scenarios. The common thread is that the borrower needs funds quickly or the property does not yet meet the criteria for long-term lending.

Property Auction Purchases

Commercial properties sold at auction require completion within 28 days (sometimes 20 days). A standard commercial mortgage cannot be arranged in this timeframe. Bridging finance allows you to complete the auction purchase, then refinance to a mortgage once the immediate deadline has passed.

Chain-Break Funding

When you have committed to purchasing a commercial property but the sale of your existing asset has not yet completed, bridging finance covers the gap. Once your sale completes, the bridge is repaid.

Property Not Yet Mortgageable

Many commercial properties do not meet the criteria for standard mortgage lending because they:

  • Are in poor condition and require refurbishment
  • Are vacant and need a tenant before a mortgage lender will consider them
  • Have short or problematic leases that need restructuring
  • Have planning issues that need resolving
  • Are undergoing change of use

Bridging finance provides the time and funds to address these issues, after which the property can be refinanced to a longer-term commercial mortgage.

Opportunistic Acquisitions

When a commercial property becomes available at a significant discount and speed is critical, bridging finance enables you to secure the deal before arranging longer-term finance.

Business Cash Flow

Commercial bridging loans can release capital from an existing commercial property to fund business operations, pay a tax bill, complete a business acquisition or meet other short-term cash needs.

Development Situations

While major developments typically require dedicated [development finance](/services/development-finance), bridging can be appropriate for:

  • Purchasing a development site before the main development facility is in place
  • Funding light refurbishment or conversion work
  • Providing short-term capital while planning permission is obtained

**Key Takeaway:** Commercial bridging finance is a tool for solving time-sensitive or structurally complex property funding challenges. It should always be used with a clear, realistic exit strategy.

How Commercial Bridging Differs From Mortgages

Understanding the differences between bridging and mortgage lending is essential for choosing the right product.

Feature Commercial Bridging Commercial Mortgage
Term 1-24 months 5-25 years
Speed Days to weeks 8-16 weeks
Interest Monthly (higher) Monthly (lower)
Exit strategy Mandatory and specific Not typically required
Property condition Flexible Must be in good condition
Tenant requirements Not always needed Usually required for investment
Arrangement fees Higher (1-2%) Lower (0.5-1.5%)
Monthly cost Higher Lower
Purpose Short-term, specific Long-term holding

Cost Comparison

Bridging finance is more expensive per month than a commercial mortgage, but for short-term use this is often irrelevant. The ability to execute quickly can generate savings or profits that far exceed the additional finance cost.

**Example**: You find a commercial property worth £500,000 available for £400,000 because the seller needs a quick sale. A 6-month bridge at 0.85% per month costs approximately £20,400 in interest plus fees. The £100,000 discount more than compensates for the higher finance cost.

Types of Commercial Bridging Loans

Regulated vs Unregulated

**Regulated bridging**: Loans secured against property that is or will be the borrower's primary residence. Regulated by the Financial Conduct Authority (FCA).

**Unregulated bridging**: Loans secured against investment properties, commercial properties or land. Not regulated by the FCA. The vast majority of commercial bridging is unregulated.

First Charge vs Second Charge

**First charge**: The bridging loan is the primary security on the property. No other mortgage takes priority.

**Second charge**: The bridging loan sits behind an existing first charge mortgage. Rates are higher because the bridging lender's position is subordinate. The first charge lender must consent to the second charge.

Open vs Closed

**Closed bridging**: You have a confirmed exit date (such as an exchanged property sale). Lower rates because the risk is lower.

**Open bridging**: No confirmed exit date, though there is still a maximum term and you must have a credible exit plan. Higher rates due to greater uncertainty.

Interest Payment Options

Commercial bridging loans offer several ways to handle interest payments:

Monthly Serviced

You pay interest monthly, similar to a mortgage. This keeps the loan balance stable but requires regular cash flow to meet payments.

Retained Interest

Interest for the expected loan term is deducted from the advance and held by the lender. You receive less cash upfront but make no monthly payments. If you repay early, unused retained interest is refunded.

Rolled-Up Interest

Interest is added to the loan balance each month and paid when the loan is repaid. The total debt increases over time, but you have no monthly payment obligations.

**Key Takeaway:** Retained or rolled-up interest is common for commercial bridging because it removes the need for monthly payments during what is often a period of no income (for example, while a property is being refurbished).

Exit Strategies

The **exit strategy** is the most critical element of any bridging loan application. Lenders must be satisfied that you can repay the loan within the agreed term.

Common Exit Strategies

  • Sale of the bridged property: The property is sold and the loan repaid from the proceeds
  • Refinance to a commercial mortgage: The property is refinanced onto a long-term mortgage once it meets standard lending criteria
  • Sale of another asset: A different property or asset is sold to repay the bridge
  • Business funds: Anticipated business receipts (such as a contract payment) repay the loan
  • Development completion: For refurbishment bridges, the improved property is refinanced or sold

What Makes a Strong Exit Strategy

  • Evidence: Supporting documentation (e.g., mortgage offer in principle, sale agreed evidence)
  • Realistic timeline: The exit must be achievable within the loan term
  • Contingency: A backup plan if the primary exit is delayed
  • Independence: Ideally, the exit does not depend on the same market conditions that created the need for bridging

Security Requirements

Commercial bridging lenders require property security for every loan:

  • Commercial property: Offices, retail, industrial, warehouses, mixed-use
  • Development sites: Land with or without planning permission
  • Semi-commercial: Properties with both commercial and residential elements
  • Multiple securities: Some lenders accept cross-charges on multiple properties to achieve higher effective LTV

Loan-to-Value

  • Standard commercial bridging: Up to 70-75% LTV
  • With additional security: Potentially higher effective LTV
  • Development bridging: Based on current value, not projected future value

Who Uses Commercial Bridging Finance?

Property Investors

Investors use bridging to acquire commercial properties quickly, refurbish them and then refinance to commercial mortgages. This **bridge-to-let** strategy is one of the most common uses.

Business Owners

Owner-occupiers use bridging to secure business premises quickly or release equity from existing commercial property for business purposes.

Property Developers

Developers use bridging for site acquisition, light refurbishment projects and gap funding between development stages.

Landlords

Existing commercial landlords use bridging to fund portfolio acquisitions, take advantage of opportunities and manage cash flow between property transactions.

Frequently Asked Questions

Below are the most common questions we receive about commercial bridging finance.

*Written by Matt Lenzie, Founder of Commercial Mortgages Broker. Ex-Lloyds Bank & Bank of Scotland.*

Frequently Asked Questions

How quickly can commercial bridging finance be arranged?

In straightforward cases, commercial bridging finance can be arranged in as little as 3-5 working days. Standard cases typically take 1-3 weeks. Speed depends on how quickly the valuation can be completed, how complex the legal title is and how promptly you provide required documentation.

What is the maximum LTV for commercial bridging?

Most commercial bridging lenders offer up to 70-75% LTV on the property's current market value. Higher effective LTV may be achievable by offering additional properties as cross-security. Some specialist lenders may go to 80% LTV for exceptionally strong cases.

Can I get a bridging loan on a vacant commercial property?

Yes, this is one of the key advantages of bridging over mortgage lending. Commercial mortgage lenders typically require the property to be tenanted, while bridging lenders are comfortable with vacant properties as long as there is a clear exit strategy (usually refurbishment and letting followed by refinance).

Do I need a deposit for commercial bridging finance?

Yes, most bridging lenders require a minimum 25-30% deposit (meaning maximum 70-75% LTV). The deposit can come from cash savings, equity in other properties or other verifiable sources. The exact requirement depends on the property type, condition and your exit strategy.

What happens if I cannot repay the bridging loan on time?

If you cannot repay within the agreed term, you may be able to extend the loan (usually for an additional fee). However, extensions are not guaranteed. If repayment is not made, the lender may take steps to recover the debt, which could include taking possession of the property. Always build contingency time into your planning.
