Before the hammer falls: how a bridging loan works for UK auction buyers

Most auction buyers understand the basic pressure: win the lot, exchange contracts immediately, complete within 28 days. What fewer understand is that the finance work starts well before the gavel falls, not after.

A bridging loan is the standard instrument for UK auction purchases. Understanding how a bridging loan works in this context means knowing three things before you bid: what a decision in principle commits a lender to, how the legal pack shapes the credit offer, and how the drawdown sequence maps onto the 28-day window.

The buyers who walk in with a paddle and a plan have done this groundwork before the auction catalogue was printed.

Getting a decision in principle before you bid

A decision in principle (DIP) is a conditional commitment from a lender that, subject to valuation and due diligence on the specific lot, it can lend up to a stated LTV. It is not a full credit approval. But it tells you, before you pay the entry fee, whether the finance is viable.

For a direct private lender, issuing a DIP typically takes 24 hours or less. The lender needs the broad parameters: property type, indicative purchase price and your intended exit (resale, refinance, or development exit). Income documents are not the main test, though KYC and background checks always apply.

The underwriting basis is what keeps this short. A bridging lender assesses the asset and the exit rather than monthly income, so the conditional offer can be settled during the viewing period, not after you have committed.

That matters when you are looking at a lot that closes in 60 seconds. If you want to confirm whether a specific property is eligible, speak to the team before the auction date rather than waiting until after.

What a lender sees when it reads the legal pack

Auction houses publish the legal pack for each lot before sale day, usually a week or two in advance. The pack typically contains the title register from HM Land Registry, any lease documents for leasehold properties, local authority searches, and the special conditions of sale. This is the document your solicitor should read, and so should your lender.

A private lender's credit team will focus on several things. Title quality comes first: is the property freehold or leasehold, and if leasehold, how many years remain? Short leases (typically below 80 years unexpired) reduce the LTV a lender can offer, because the asset becomes harder to sell at full value.

Restrictive covenants, rights of way, and any planning conditions affecting future use also matter. For larger transactions, due diligence scales accordingly: the large bridging loans page covers the specific parameters that apply at that end of the market.

The practical point is simple: share the legal pack with your lender as soon as it is published, not after the hammer falls. A lender who has reviewed the pack before the auction can give a tighter, more reliable conditional offer. One who sees it for the first time on day one of the 28-day window will be slower, and may need to revise their initial indication.

The drawdown sequence from hammer to completion

Understanding how a bridging loan works means understanding the clock. Here is the typical sequence for a UK auction purchase.

Day 0. The hammer falls. Contracts are exchanged immediately and you pay the 10% deposit (or the percentage specified in the auction house terms). Instruct your lender and your solicitor the same afternoon.

Days 1–5. The lender formally instructs a valuer. Your solicitor receives the legal pack and begins the Report on Title for the lender's legal team. Both parties work in parallel from day one.

Days 6–10. The RICS valuation is completed. For a residential or commercial lot in a major city, this typically takes five to seven working days from instruction. The lender's credit team reviews the valuation alongside the Report on Title.

Days 11–18. Credit is formally approved and the facility letter is issued. Both sets of solicitors work through title transfer, Land Registry searches, and any special conditions in the pack.

Days 19–28. Funds are drawn down and completion occurs. For a worked example, see the Hampstead case study.

Rikvin Capital issues a term sheet within 24 hours of instruction. Drawdown typically completes in about two weeks, and in urgent cases inside seven days. The Rikvin Capital lending process runs in a direct line from DIP to drawdown.

When a bridging loan is and is not the right tool

A bridging loan fits an auction purchase when three conditions are met. The asset must have clear security value. The borrower must have a credible exit within the loan term. And the total cost of the bridge must sit comfortably within the deal's economics.

It is the wrong tool when the exit is speculative. A buyer planning to refinance onto a buy-to-let mortgage needs to confirm that the property will satisfy a standard mortgage lender's criteria after purchase. A buyer relying on resale needs a realistic read on demand and timing in that specific market, not a hope.

The main risk is straightforward: if the exit fails or is delayed, rolled-up interest accumulates and the total cost rises. Private lenders will often allow term extensions, but at additional cost and not unconditionally. Go into an auction with a primary exit and a credible backup.
