Commercial Bridging Loans

You have found a commercial property. The deal is good. The problem is time.

A commercial mortgage can take two to four months to complete. The vendor will not wait that long. This is the gap a commercial bridging loan is built to close.

Below, we explain how it works, what it costs, and, just as importantly, where it can go wrong.

What is a commercial bridging loan?

A commercial bridging loan is short-term finance secured against a commercial or semi-commercial property.

It gives you fast access to capital while a longer-term plan comes together. That plan might be a sale, a refinance onto a commercial mortgage, or a refurbishment that makes the building lettable.

The loan is designed to be temporary. Terms usually run from 1 to 18 months, occasionally up to 24.

The lender secures the loan against property rather than against your trading accounts. That changes the whole assessment. A commercial mortgage looks hard at your income and credit history. Commercial bridging finance looks first at the asset and your exit.

The question a bridging lender asks is not "can you afford the monthly payments for the next 15 years?"

The question is "how are you going to pay this back, and when?"

Commercial vs semi-commercial: where your property sits

The label matters, because it affects which lenders will look at your deal and at what rate.

• Commercial: The property is wholly business-use: offices, retail units, warehouses, industrial units, hotels, pubs, restaurants, healthcare, leisure.
• Semi-commercial (also called mixed-use): The property combines commercial and residential space. A shop with a flat above is the classic example.

As a rough guide, a property is treated as commercial when more than 40% of its value or floor space is business-use. Below that threshold, it may be assessed as semi-commercial, which can open up keener pricing.

If you are unsure which side of the line your property falls, tell your broker early. It shapes the whole quote.

What can you use it for?

A commercial bridging loan is flexible. Common uses include:

• Buying at auction, where completion is fixed at 28 days
• Beating a chain break or a motivated vendor's deadline
• Refurbishing or converting a run-down unit before letting or selling it
• Change of use, for example, turning offices into flats or a shop into a café
• Capital raising against a property you already own, to fund the next deal
• Refinancing an existing facility that is coming to an end
• Business purchases, acquiring premises, a competitor, or a going concern

The common thread is speed. A commercial bridging loan earns its place when a conventional route is too slow to catch the opportunity.

What types of property can be secured?

Most commercial and mixed-use buildings can be considered, including:

• Offices and business units
• Retail and high-street premises
• Industrial units and warehouses
• Hotels, pubs, restaurants and other hospitality
• Healthcare and care facilities
• Land with planning
• Some land without planning
• Non-standard or unusual buildings

Lenders differ widely on what they will accept. A specialist may consider a former bank, a church, or a property in poor repair that a high-street lender would decline outright. The rate reflects the risk, but the door is rarely fully closed.

How fast is "fast"? An honest answer

Some lenders advertise commercial bridging finance completed in 24 hours. In almost all cases, this is marketing, not reality.

A commercial deal needs a valuation, legal work, and searches. On a clean case with an experienced solicitor and no surprises, that is realistically 2 to 4 weeks.

Simple deals move faster. Complex ones, unusual security, incomplete paperwork, a slow valuer, take longer.

The honest position is this. A quick commercial bridging loan is measured in weeks, not hours. Anyone telling you otherwise is selling you the exception as if it were the rule.

Speed comes from preparation, not promises. You move fastest when your valuation is instructed early, your solicitor is ready, and your exit is evidenced from day one.

Commercial bridging loan rates

Commercial bridging is priced monthly, not annually, because the loan is short-term.

In 2026, commercial bridging loan rates generally start from around 0.75% per month, with most cases landing between 0.75% and 1.25% per month. Stronger deals, low loan-to-value, clean security, an evidenced exit, sit at the bottom of that range. Complex or higher-risk cases sit above it.

Commercial security is priced higher than residential. The reason has little to do with you as a borrower.

It is about how quickly the property could be sold if things went wrong. A house in a commuter town has thousands of buyers and a predictable price. A specialist commercial unit does not. The lender prices that difference in.

For context, the Bank of England base rate stood at 3.75% in mid-2026. Bridging does not track base rate directly, but a lender's cost of funds does, so pricing can move over time. Always confirm live rates before you rely on a figure.

How interest is charged

There are three structures, and the difference affects how much cash you need up front:

• Rolled-up (compounded): Interest is added to the loan and settled in full at the end. You pay nothing monthly. This is the most common choice on commercial bridging.
• Retained: The lender deducts the interest for the expected term at the outset, so you borrow slightly more but make no monthly payments.
• Serviced: You pay the interest monthly, like a mortgage. This keeps the final repayment lower but requires monthly cash flow.

What it costs beyond the rate

The headline rate is never the whole picture. Budget for:

• Arrangement (product) fee: typically around 2% of the loan, often added to the balance
• Valuation fee: Paid to an independent surveyor
• Legal costs: Usually both your own and the lender's
• Telegraphic transfer fee: A small charge to release funds
• Broker fee: Where a broker is used
• Exit fee: Some, though not all, lenders charge one

Your loan-to-value is calculated on the total borrowed, including any fees added to the loan. It is worth modelling the full cost, not just the monthly interest, before you commit.

Using a commercial bridging loan calculator

A commercial bridging loan calculator is a useful starting point. Enter the property value, the loan you need, the term and the rate, and it will estimate your monthly interest and the total to repay.

Treat the result as an indication, not a quote. A calculator cannot see your exit, your credit profile, or the quirks of your security and those are what set your final terms.

How much can you borrow?

This varies across the market. Loans commonly range from around £50,000 up to £25 million and beyond, depending on the lender and the deal.

Loan-to-value is usually capped at 70-75% of the property's value on a first charge. Higher gearing may be possible with additional security.

Both first and second charge options exist. A second charge sits behind an existing loan on the property and is generally priced higher to reflect the added risk.

Your exit strategy is everything

This is the part that decides whether a bridge is a smart tool or an expensive mistake.

A commercial bridging loan does not disappear at the end of the term. You have to repay it. The route you use to do that is your exit.

The two most common exits are:

• Refinance: Moving onto a commercial mortgage or buy-to-let facility once the property is income-producing or the works are done
• Sale: Selling the property, or another asset in your portfolio, to clear the balance

Other exits include a business sale, an inheritance once probate completes, or a pension drawdown.

Here is the discipline that matters. Price the term you actually need, then add slack.

A bridge arranged for six months that runs to ten will cost you more than one arranged honestly for ten from the start. Extensions carry fees. Default interest is materially higher than your agreed rate. Overruns are where bridging gets expensive.

Evidence your exit before you draw the funds. A soft exit is a bridge that overruns.

The risks, stated plainly

A commercial bridging loan is a powerful tool. It is also a serious commitment, and honesty about the downside serves you better than a sales pitch.

• It costs more than a mortgage. You are paying for speed and flexibility. Over a short term that trade can make sense; over a long one it rarely does.
• Your property is at risk. The loan is secured. If you cannot repay and cannot refinance, the lender can enforce against the security.
• The exit is the single biggest risk. If your sale falls through or your refinance is declined, the loan still has to be repaid.
• Fees add up. Arrangement, valuation, legal and exit fees all sit on top of the interest.

None of this is a reason to avoid bridging. It is a reason to use it deliberately, for the right deal, with a clear way out.

Is commercial bridging regulated?

In most cases, no.

When a bridging loan is secured against a commercial or investment property, it usually falls outside Financial Conduct Authority regulation. That is normal for this type of lending.

Regulation typically applies only where the security is a property you or a close family member lives in. Most commercial bridging is unregulated, which is part of why it can move quickly, but it also means fewer of the consumer protections that apply to a residential mortgage. Take advice before you commit.

What makes the best commercial bridging loan for you

The best commercial bridging loan is not simply the one with the lowest advertised rate.

The cheapest rate on paper can cost you more if the term is too short, the minimum interest period is long, or the exit does not fit your plan.

Weigh the whole picture:

• The total cost across the months you will actually hold the loan
• Whether the term gives you genuine breathing room
• How well the exit matches your real-world timeline
• The lender's track record with your property type
• The certainty of completion, a keen rate is worthless if the deal collapses at week three

The right loan is the one that completes on time, fits your exit, and leaves you room if the timeline moves.
