Bridging Finance Jargon Buster: Key Terms Explained

Bridging finance jargon, in plain English

Bridging finance carries more jargon than almost any other type of property lending, and the words genuinely change what you can borrow and what it costs. This is a plain-English glossary of the terms we explain to clients most often — grouped by what they affect: the amount you receive, the cost, the type of bridge, the legal side, and the exit. It is general information, not advice; where a term deserves a full guide, we have linked one.

New to bridging? Start with the full guide: what are bridging loans and how do they work.

The amount you borrow and receive

Gross loan

The headline figure a bridge is set at — the total you are contracting to repay. It is the number quoted first, but it is not the cash that reaches you, because the lender typically deducts certain costs from it before release. The gap between the gross loan and what lands in your account is the single most misunderstood thing in bridging.

Full guide: gross vs net bridging loans

Net loan (net advance)

The money that actually reaches you after deductions come off the gross loan — commonly the arrangement fee and, depending on structure, an interest allowance. The net figure is the number your plan has to survive on, so work it out before you commit rather than assuming you will receive the gross.

Loan-to-value (LTV)

The loan expressed as a percentage of the property’s value. It sounds simple, but on a bridge it interacts with the valuation basis: a headline LTV applied to a cautious value can give far less than the same LTV applied to open market value. LTV governs how much a lender will advance.

Day-one advance

The amount released at completion, as opposed to money held back and released later (for example, works funding drawn in stages on a refurbishment). Distinguishing your day-one figure from your total facility matters for cash flow — you need enough on day one to complete, and enough in reserve for what follows.

The cost and how interest is charged

Retained interest

Interest for the expected term is calculated up front and held back from the loan, so you make no monthly payments and if the loan is repaid before the term ends you should receive the interest for the remaining term back. It reduces the net you receive but suits borrowers with no income from the property during the term.

Full guide: rolled-up, retained or serviced interest

Rolled-up interest

Interest accrues over the term and is added to the balance you repay at the end, rather than being paid monthly. Nothing leaves your pocket while the bridge runs, but the amount owed grows “compounds” month by month — so a longer term costs more even at the same rate.

Serviced interest

You pay the interest each month while the bridge runs, like an interest-only arrangement, keeping the balance flat. It suits borrowers with income to cover the payments and can leave more of the gross loan available to you. Retained, rolled-up and serviced are three different mechanisms, not synonyms.

Arrangement fee

The lender’s fee for setting up the facility, often included in the loan rather than paid separately. It is one of the deductions that turns a gross loan into a smaller net advance, so it belongs in your cost picture from the start alongside valuation and legal costs.

Types and structures of bridge

Open bridge

A bridge with no fixed, contractually-certain repayment date — for example, where you intend to sell but have not yet exchanged contracts. Lenders scrutinise the exit harder on an open bridge because the repayment moment is a plan rather than a certainty, and that can shape terms and appetite.

Closed bridge

A bridge with a defined, evidenced repayment event already in place — typically an exchanged sale contract or an agreed refinance with a completion date. Because the exit is contractually certain, a closed bridge is generally viewed as lower risk than an open one.

Regulated bridging

A bridge secured against a property that has been, is, or is intended to be occupied as a dwelling by the borrower or a close family member — which brings it inside the FCA’s mortgage regime and its consumer protections. Whether a bridge is regulated follows the security, not the purpose or the lender.

Non-regulated (unregulated) bridging

A bridge for investment or commercial property that nobody connected to the borrower occupies as a home is treated as a commercial arrangement outside the FCA’s mortgage-conduct rules, with the borrower as a business client. Most of the bridging market operates here.

Bridge-to-let

A bridge used to buy and refurbish a property that is not yet mortgageable, paired with a planned refinance onto a buy-to-let mortgage as the exit. The “let” is the point: it is for buying to keep and rent, not to sell, and the exit is a mortgage rather than a sale.

Valuation terms

Open market value (OMV)

What a property would likely sell for in a normal sale, properly marketed, with no time pressure — usually the highest of the figures a surveyor reports. It is the starting point, but not always the figure a bridging lender chooses to lend against.

90-day or 180 day / restricted-marketing value

The likely sale price assuming a short, pressured marketing period. Because bridging lenders need confidence they could recover quickly if the exit fails, many lend against this more conservative figure rather than OMV — which is why the valuation basis can constrain your loan more than the rate does.

Gross development value (GDV)

The estimated value of a project once the planned works are complete — used on refurbishment and conversion cases to size lending against the finished, not the current, state. A cautious, evidenced GDV underpins the deal; an over-optimistic one is a common reason a case is cut back.

Desktop / AVM / full valuation

The three broad ways a property is assessed: an automated valuation model (AVM) or a desktop review, quicker and used on lower-risk standard property; or a full physical inspection, usually needed on higher-value, unusual, or commercial security. The route is matched to the property and the risk.

Legal and security terms

First charge

The lender registered with first priority against a property — first to be repaid from a sale. Where a property has no existing mortgage, a bridge takes the first charge, which is the simpler position with the widest lender pool.

Second charge

A charge that sits behind an existing first charge, so the first lender keeps priority and the second-charge lender is repaid only after them. It lets you raise money without disturbing your main mortgage, but usually needs the first lender’s consent and leaves less equity beneath it.

Equitable charge

This is a method used by lenders to secure a second charge on the equity in a property where the first charge lender does not grant them permission to lend. Lenders have watered down possession rights and as such often charge a higher interest rate.

Cross charge (additional security)

Where a lender takes security over more than one property — commonly a property you already own alongside the one you are buying — so their overall position is covered. It is how many “no deposit” or full-purchase-price cases are structured, and it depends on genuinely usable equity in the extra security.

Deed of postponement / first-charge consent

The existing first-charge lender’s formal agreement to a new charge being registered behind them. Many mortgage agreements require it before a second charge can go on, and a slow or refused consent is one of the most common reasons a straightforward-looking second-charge case stalls.

Dual vs single representation

Dual representation is one solicitor acting for both borrower and lender (faster, often cheaper, common on clean cases) and removes independent legal advice; single representation is each side instructing its own firm (usual on higher-risk or adverse cases). On bridging you usually pay the lender’s legal costs as well as your own.

Exit and process terms

Exit strategy

How the bridge gets repaid — almost always a sale or a refinance onto a longer-term mortgage. It is the first thing a lender assesses and the single biggest reason cases succeed or fail: a bridge is only ever as good as its exit, which needs to be credible and evidenced, not hoped for.

Staged drawdown

On refurbishment and conversion cases, works funding released in tranches as the project reaches defined milestones, often signed off by a monitoring surveyor. With rolled-up interest you generally pay only on funds actually drawn — but you need working capital to reach each stage before the next tranche lands.

Chain break

Using a bridge to proceed on a purchase when your own sale has fallen through or been delayed — secured against your existing home so you do not lose the property you are buying. Because the security is your residence, a chain-break bridge is usually regulated.

How Niche Advice can help

Bridging jargon — frequently asked questions

What is the difference between the gross and net loan on a bridge?

The gross loan is the headline figure you contract to repay; the net loan (or net advance) is what actually reaches you after deductions such as the arrangement fee and, depending on structure, an interest allowance. Plan around the net figure, not the gross.

What’s the difference between retained, rolled-up and serviced interest?

Retained interest is held back from the loan up front; rolled-up interest accrues and is added to the balance repaid at the end; serviced interest is paid monthly as you go. They are three different mechanisms, and which suits you depends on your income and the deal.

What is an open bridge versus a closed bridge?

A closed bridge has a fixed, evidenced repayment event already in place (such as an exchanged sale); an open bridge does not yet have a contractually certain exit date. Lenders scrutinise open bridges more closely because the exit is a plan rather than a certainty.

Why does the valuation basis matter more than the interest rate?

The rate is applied to a loan amount, and the loan amount is driven by the valuation the lender chooses to use. A lender lending against a cautious 90-day or 180-day figure rather than open market value can shrink your loan far more than a small difference in rate would.

What makes a bridging loan regulated?

A bridge is regulated where the security is a property that has been, is, or is intended to be occupied as a dwelling by the borrower or a close family member. It follows the security property, not the purpose of the loan or the choice of lender.

What is a cross charge in bridging?

A cross charge is where the lender takes security over more than one property — typically one you already own alongside the one you are buying — so their overall position is covered. It depends on genuinely usable equity in the additional security.

Closing

You do not need to master the vocabulary to use a bridge well — that is the broker’s job — but knowing what the words actually change helps you ask the right questions. If a term here describes your situation, that is the conversation worth having. This is general information, not advice on your case.
