Large Bridging Finance: Loans from £500K to £25M Explained

Large bridging finance is a short-term loan secured against property or land, typically starting at £500,000 and extending to £25M or beyond for the right asset and borrower profile. Like all bridging loans, these facilities are designed to bridge a gap — between purchase and refinance, between acquisition and planning consent, or between a development completing and a long-term mortgage being arranged.

The mechanics of a bridge loan are straightforward. A lender advances a single lump sum secured by a legal charge (first or second) over one or more properties. Interest accrues monthly but is usually rolled or retained rather than serviced, so the borrower repays the principal plus accumulated interest at exit. The exit — refinance, sale, or completion of another liquidity event — must be clearly defined at the outset. Speed is the defining feature: a well-prepared large bridging application can complete in 5–21 days where a comparable commercial mortgage would take 6–12 weeks.

The defining characteristics of large bridging finance are speed, asset focus, and flexibility. Lenders underwrite primarily against the value of the security rather than the borrower's income, which makes the product accessible to limited companies, special purpose vehicles (SPVs), trusts, experienced investors, and overseas borrowers who may not qualify for mainstream mortgage products.

At the larger end of the market — transactions above £2M — facilities are frequently bespoke. Lenders such as Shawbrook, Together, West One and OakNorth each operate in this space, but high-value loans often require direct negotiation on pricing, structure, and drawdown mechanics rather than an off-the-shelf product. Working with a broker who has established relationships across 100+ lenders is material to accessing the best terms at this scale.

Large bridging finance is distinct from development finance in that it does not typically involve staged drawdowns against a construction programme. It is a single advance (or occasionally a two-stage facility) secured against existing or near-existing value. Where ground-up construction is involved, the correct product is usually a development loan rather than a bridge.

The commercial case for large bridging finance is straightforward: speed and certainty of funding unlock opportunities that would be lost waiting for conventional mortgage underwriting. The following scenarios account for the majority of large bridging transactions in the UK market.

• Auction purchases: Completion is typically required within 28 days. A large bridging loan can be arranged and drawn in time where a commercial mortgage cannot. See our guide to bridging loans for auction purchases.
• Chain-break purchases: A buyer whose onward sale has collapsed can use bridging finance to proceed regardless, then repay once their existing property sells.
• Permitted development and light refurbishment: Properties requiring work before they meet mortgage lender standards are bridgeable; the loan is repaid once the asset is refinanced or sold.
• Commercial-to-residential conversions: Acquiring an office, warehouse, or retail unit for conversion to residential use before refinancing onto a development exit or buy-to-let mortgage.
• Portfolio refinancing: Releasing equity across multiple assets simultaneously, often using a cross-charge structure, to fund new acquisitions.
• Heavy refurbishment and change of use: Where works are significant but the site is not a ground-up build, bridging is typically the appropriate vehicle.
• HMO conversions: Acquiring a house for conversion to a multi-occupancy HMO, with the bridge repaid on completion of licensing and refinance onto a term HMO mortgage.
• Land acquisition ahead of planning: Securing a site before planning permission is granted, with the exit being either a development finance facility post-consent or an outright sale.

Each of these use cases demands a clear, credible exit strategy — the single most important factor in any large bridging application. Lenders will scrutinise whether the exit is realistic within the term, and a vague or aspirational exit will either kill the deal or result in punitive pricing.

Large bridging finance is priced monthly rather than annually. Market rates across the UK specialist lending sector currently range from approximately 0.55% p.m. to 1.20% p.m. depending on LTV, asset type, borrower experience, and the strength of the exit strategy. The table below summarises typical parameters for high-value bridging facilities.

At loan sizes above £5M, pricing becomes highly negotiable. Lenders factor in the quality of the sponsor — track record, net worth, liquidity — alongside the asset. A borrower with a strong balance sheet and a clean exit may achieve rates at or below the bottom of the quoted range. Conversely, a complex asset (mixed-use, short lease, unusual title) will attract a premium regardless of borrower quality.

Interest on large bridging loans is most commonly retained or rolled — meaning it is added to the loan balance and repaid in full at exit, rather than paid monthly. This preserves cashflow during the term, which is particularly useful where the asset is not generating income while works are being carried out. Retained interest structures do, however, reduce the net advance, so it is important to model the true loan-to-cost carefully before committing.

Large bridging facilities are always secured against real property. The lender takes a legal charge — first or second — over one or more assets, which it can enforce if the borrower defaults and the debt cannot be recovered. Understanding how security structures work is essential when arranging high-value facilities.

A first charge gives the lender priority over all other creditors in the event of enforcement. Most large bridging lenders require a first charge, particularly on residential security. Second charge bridging is available but typically carries a higher rate and lower LTV, reflecting the increased risk to the lender.

Cross-charging — where the loan is secured against two or more properties simultaneously — is common in large bridging transactions. It allows borrowers to achieve a higher overall LTV against the combined portfolio than any single asset would support individually. For example, a borrower acquiring a commercial property at a 70% LTV may offer an unencumbered residential investment property as additional security to reduce the effective LTV and improve pricing.

Security can include residential property (houses, flats, HMOs, new builds), commercial property (offices, retail, industrial, hotels), mixed-use assets, land with or without planning, and development sites at varying stages of completion. Each asset class carries its own valuation methodology, and lenders will instruct a surveyor from their approved panel. The borrower bears the cost of this valuation.

For transactions involving multiple assets, a specialist bridging broker will typically negotiate a single facility agreement covering all security, rather than separate loans per property. This simplifies the legal process and usually delivers better economics than multiple smaller facilities.

Every large bridging loan must have a clearly articulated exit strategy. Lenders will not advance funds without understanding precisely how and when the loan will be repaid. The exit is typically one of three routes: refinance onto a long-term product, sale of the asset, or repayment from another liquidity event.

Refinance is the most common exit for investment and commercial bridging. The borrower completes a refurbishment or conversion, the asset is revalued at its improved worth, and a buy-to-let mortgage, commercial mortgage, or development exit finance facility replaces the bridge. The viability of this exit depends on the post-works value, the expected rental income, and the borrower's ability to meet the refinance lender's criteria at that point.

Sale is a straightforward exit for assets being acquired below market value (auction purchases, distressed sales) or for development projects where the end strategy is disposal rather than retention. The risk is market timing — if sale is the only exit, lenders will want evidence of demand and a realistic marketing timeline within the loan term.

A repayment from another liquidity event — completion of a separate property sale, a business transaction, or an inheritance — is accepted by some lenders but treated with caution. The more contingent the exit, the higher the rate and the more likely the lender is to require a secondary exit strategy as a backstop.

For large bridging loans where the exit is a development finance facility (i.e., the bridge is used to acquire land and the development loan will follow post-planning), lenders will want to understand the planning strategy and the intended development finance terms. Our guide to development finance vs bridging loans covers the transition between the two products in detail.

The large bridging market is not a commodity market. Unlike residential mortgages, there is no single rate card that applies to every borrower. Lenders price based on a combination of asset quality, borrower profile, exit credibility, and — critically — their own book composition at the time of application. A lender who is overexposed to commercial property may decline or price aggressively on a commercial deal irrespective of its individual merits.

This is why broker access matters at the large end of the market. A broker with relationships across 100+ lenders can identify which institutions are actively writing large bridging business, which have appetite for the specific asset type, and which will move fastest given the borrower's timeline. Across Matt's 25+ years in this market he has arranged large bridging facilities for acquisitions, refurbishments, auction purchases, and portfolio restructurings across the UK.

The process for arranging a large bridging loan typically moves as follows: initial conversation and indicative terms (24–48 hours), formal application and document pack (valuation, title, borrower information), credit approval and offer (typically 5–10 working days for experienced lenders), legal completion (dependent on solicitor timelines, usually 2–4 weeks). Urgent transactions — particularly auction completions — can be compressed significantly with the right lender and preparation.

Documentation requirements for large bridging applications include proof of identity, evidence of the asset's current value (or a desktop/AVM for speed), confirmation of the exit strategy, company or personal financial information, and planning documentation where relevant. Due diligence is focused and commercial rather than bureaucratic — but being well-prepared before approaching lenders is the single most effective way to shorten the time to completion.
