Bridging Loans: How Short-Term Property Finance Works

A bridging loan is a form of short-term secured lending, typically against property, used to bridge a financing gap while longer-term funding is arranged or a property is sold. In the right circumstances, bridging finance is a powerful tool — enabling transactions that would otherwise be impossible to complete on the buyer's or developer's timeline. Used carelessly or without a robust exit strategy, it can become expensive and potentially dangerous.

This guide provides a comprehensive overview of how bridging loans work, the cost framework, the distinction between regulated and unregulated lending, and how to think about bridging as part of a broader property finance strategy.

What Is a Bridging Loan Used For?

Bridging loans are used across a range of property scenarios, including:

• Purchasing at auction: Auction completions typically require funds within 28 days, which is too short for a standard mortgage. A bridge funds the purchase; a mortgage is arranged subsequently.
• Chain break: A buyer who has found a new property but not yet sold their existing home can use a bridge to proceed with the purchase before the sale completes.
• Property conversion and refurbishment: Properties that are unmortgageable in their current state (derelict, uninhabitable, or requiring planning consent) can be bridged until they become lendable.
• Development finance: Ground-up development or significant conversion projects often use bridging or development finance during construction, refinanced to a term mortgage or sold on completion.
• Capital injection pending asset sale: Where an investor needs liquidity quickly and a longer-term asset is being marketed for sale.
• Land purchase with planning uplift: Purchasing land that may benefit from planning permission before a more permanent finance arrangement can be established.

Closed vs Open Bridging Loans

The most fundamental distinction in bridging is between closed and open bridges:

Closed bridge: The exit date is fixed and certain. The most common example is a borrower who has exchanged contracts on the sale of a property — the sale completion date is set, the proceeds are guaranteed (subject to normal conveyancing risk), and the lender knows precisely when the bridge will be repaid. Closed bridges are lower risk for lenders and are therefore generally priced more cheaply.

Open bridge: There is no fixed repayment date within the loan term. The borrower expects to repay — through a sale, a remortgage, or other means — but no completion date is contracted. Open bridges carry more lender risk and are priced accordingly, and lenders are likely to scrutinise the exit strategy more carefully. Most open bridges have a maximum term, typically 12 months, sometimes extended to 18 or 24 months.

In practice, many bridging transactions fall somewhere between the two: the borrower has a credible and likely exit within the term but has not yet contracted it. Lenders assess the quality of the exit strategy as a central part of underwriting.

Regulated vs Unregulated Bridging

Bridging loans are regulated by the Financial Conduct Authority when they are secured against a property that the borrower (or a close family member) occupies or intends to occupy as their main residence. This is referred to as a regulated bridging loan or regulated mortgage contract.

Unregulated bridging loans are those secured against investment properties, commercial properties, or land. The majority of bridging transactions in the UK are unregulated, since they involve investment or development rather than a borrower's home.

The distinction matters because:

• Regulated loans require the lender to provide a Key Facts Illustration (KFI) and comply with FCA conduct of business rules
• Regulated bridging must be arranged by a firm authorised to conduct regulated mortgage business
• Enforcement procedures against a regulated borrower are more constrained than against an unregulated one
• Consumer protection obligations, including affordability assessments, apply to regulated loans

Borrowers taking a bridging loan on their main residence should ensure they are using a regulated lender or a regulated intermediary. Using an unregulated bridge for a residential purpose — even if the purpose is technically valid — does not attract the same consumer protection.

Monthly Interest Rates vs APR

Bridging loans are quoted in monthly rates rather than annual rates, which can obscure the true cost. A rate of 0.75% per month sounds modest; it equates to an annual rate of approximately 9%–10% when compounding is applied. Rates in the bridging market as of 2026 typically range from 0.55% per month (for very low-risk, closed bridge transactions with excellent security) to 1.5%+ per month for higher-risk cases.

APR (Annual Percentage Rate) is a more meaningful comparison metric, as it includes fees and compounds the interest over a full year. However, since most bridges are short-term (typically 3–12 months), the APR can be misleadingly high — a 12-month bridge at 0.75% per month with a 2% arrangement fee has an APR of approximately 11%–12%, but the actual cost on a six-month bridge is substantially lower in cash terms.

Arrangement fees are typically 1%–2% of the loan value, charged on completion. Some lenders also charge:

• Exit fees: 0.5%–1% of the loan on repayment (less common but present)
• Valuation fees: Site-specific but can be £1,000–£3,000+ for specialist properties
• Legal fees: Both lender's and borrower's legal costs are typically the borrower's responsibility
• Administration/commitment fees: Payable upfront to reserve the facility

True Cost Calculation

To understand the true cost of a bridging loan, borrowers should model the total outgoings rather than the headline rate. A simple illustration:

Bridge of £500,000 at 0.85% per month, 9-month term:

• Monthly interest: £4,250
• Total interest over 9 months: £38,250
• Arrangement fee at 1.5%: £7,500
• Valuation fee: £1,500
• Legal fees (both sides): £3,000 estimated
• Total bridging cost: approximately £50,250 (approximately 10% of the loan over nine months)

Whether this cost is justified depends entirely on what the bridge enables. If the transaction delivers a profit or capital gain materially in excess of the bridging cost, it is likely worthwhile. If the bridge is simply enabling a residential purchase that is slightly delayed, the cost-benefit analysis is less compelling.

Interest can be structured in several ways:

• Rolled up / retained: No monthly payments; all interest accrues and is repaid at exit. This preserves cash flow but increases the effective loan size.
• Serviced: Monthly interest is paid by the borrower throughout the term, reducing the total amount owed at exit.
• Partly retained, partly serviced: A hybrid approach.

Rolled-up interest is most common in development and investment contexts where the property is generating no income during the term.

Exit Strategy: The Non-Negotiable Requirement

Every bridging lender requires a credible exit strategy — a clear, documented explanation of how the loan will be repaid. This is the most important element of a bridging application; without a convincing exit, no reputable lender will proceed.

Common exit strategies:

• Sale of the bridged property — requires a realistic current valuation and a credible marketing timeline
• Remortgage to a term mortgage — requires confirmation of eligibility for the term mortgage (often via a decision in principle)
• Sale of another property
• Receipt of agreed funds (e.g., a contractual payment, inheritance, business sale proceeds)

Lenders will scrutinise the quality and certainty of the exit. For a remortgage exit, for example, they will want to know whether the property will be mortgageable on the conventional market after any planned works, and whether the borrower will qualify for the mortgage they are planning to take.

Second Charge Bridging

A bridging loan can be arranged as a second charge against a property that already has a first charge (typically a standard mortgage). Second charge bridging is more expensive than first charge because the second charge lender has a subordinate claim on the security — if the property is sold in a repossession, the first charge lender is repaid first, and the second charge lender only receives the residual.

Second charge bridges are used where the first charge lender will not consent to a remortgage or where early repayment charges make it uneconomic to refinance the first charge.

Development Bridge vs Standard Bridge

For ground-up development or significant conversion projects, a development bridge (or development finance facility) is structured differently from a standard bridge. Rather than releasing the full loan on day one, development finance is released in tranches as construction milestones are met — similar to a self-build mortgage. This staged drawdown reduces the lender's risk profile and the borrower's interest burden in early stages.

Development finance also typically funds a higher percentage of development costs (GDC) but a lower percentage of the end value (LTGDV — loan to gross development value). Rates and fees tend to be higher than standard bridging.

Key Bridging Lenders

The bridging market includes both regulated banks and specialist unregulated lenders. As of 2026, established bridging lenders include MT Finance, West One Loans, Precise Mortgages (part of OSB Group), Together Money, Shawbrook Bank, LendInvest, InterBay, and UTB (United Trust Bank). New entrants and challenger lenders are active in the market. Lenders' appetites, rates, and criteria change frequently, and a specialist bridging broker is strongly recommended.
