Refurbishment bridging loans for commercial buildings

A refurbishment bridging loan is short-term finance secured on a commercial building that pays for the purchase and the works needed to improve it, with the loan repaid once the upgraded property is sold or refinanced. It suits offices that need a full strip-out, tired retail and industrial units, mixed-use buildings and hotels being repositioned: anything a term lender will not fund in its current condition.

We arrange refurbishment bridging finance with a broad panel of bridging lenders, from specialist lenders to private credit funds. This page explains how lenders separate light from heavy works, how works money is released in stages, what the monitoring surveyor does, and how lending against the value on completion (GDV) changes how much you can raise.

Key takeaways
  • A refurbishment bridging loan funds the purchase on current value and the works in stages, repaid from sale or refinance.
  • Lenders separate light (cosmetic) from heavy (structural) works, which changes leverage, monitoring and lender choice.
  • Total facility is capped against GDV, so a well-evidenced value after works lets you borrow more.
  • Works money is usually released in arrears after monitoring surveyor sign-off, so plan your working capital.
  • The exit must allow time for the works, letting or sale, not just the build programme.

What counts as light or heavy refurbishment on a commercial property?

Lenders sort refurbishment into two broad buckets because the risk is different. Light refurbishment is cosmetic and non-structural: decoration, new floor coverings, replacement kitchens and WCs, rewiring, new heating, upgraded lighting and suspended ceilings. Heavy refurbishment involves structural alteration, extensions, reconfiguring floor plates, new roofs, or works that need full planning permission or building regulations sign-off beyond minor notifications.

FeatureLight refurbishmentHeavy refurbishment
Typical worksCosmetic upgrades, M&E renewal, fit-outStructural alteration, extensions, reconfiguration
PlanningUsually none neededOften required, sometimes with change of use
Building regulationsLimitedFull approval and completion certificate
Works fundingSingle tranche or a few stagesStaged drawdowns against monitored progress
Monitoring surveyorSometimesAlmost always
Lender poolWideNarrower, may overlap with development finance

The line between the two is not fixed and each lender draws it slightly differently. Our light vs heavy refurbishment guide covers the definitions in detail. If the works amount to a ground-up rebuild, development finance is usually the better fit.

How does a refurbishment bridging loan work from offer to exit?

The structure has two parts. The day-one advance funds the purchase (or refinances an existing loan) and is sized against the current open market value. The works facility pays for the refurbishment and is released in stages as the work is done.

  1. Terms in principle: we present the property, purchase price, schedule of works, costings, contractor details and exit to suitable lenders.
  2. Valuation: a RICS valuer reports both the current value and the value on completion (GDV) of the refurbished building.
  3. Monitoring surveyor review: on heavier schemes, the lender's surveyor checks the costs, programme, contractor and consents before offer.
  4. Legal work and completion: solicitors deal with title, the first charge, any debenture and guarantees, then the day-one funds are released.
  5. Staged drawdowns: works money is paid in arrears after each inspection confirms progress.
  6. Exit: the loan is repaid from a sale or refinance on the improved value.

See how it works for the general process we follow on every application.

How much can you borrow against current value and GDV?

Refurbishment bridging finance is usually tested against two limits at once:

For example (illustrative): a vacant office bought for £1,000,000 with a £400,000 works budget and a valuer's GDV of £1,800,000. A lender advancing 70% of purchase (£700,000), the full works budget (£400,000) and around £150,000 of rolled interest and fees would have a total facility of £1,250,000, roughly 69% of GDV. You would fund the £300,000 balance of the purchase plus costs from your own resources.

Try the figures in our bridging loan calculator. Lenders cap LTGDV lower on specialist assets and secondary locations, and they will want to see that the GDV is evidenced by comparables, not assumed.

How are works funds released, and what does the monitoring surveyor do?

Most lenders release works money in arrears: you or your contractor fund each stage, then the lender reimburses it once the monitoring surveyor has inspected and signed off the work. This means you need working capital to cover at least the first stage. Some lenders will release a small first tranche at completion for light works.

The monitoring surveyor acts for the lender, not you. Their role typically includes:

Their fees and the cost of each visit are normally paid by the borrower. Agreeing a sensible number of drawdown stages at the outset avoids paying for more visits than the project needs.

What do lenders check before they fund a refurbishment?

Lenders look at three things: the building, the plan and the people.

First-time refurbishers can still borrow, particularly on light works, but expect lower leverage and a closer look at the professional team. Bringing a detailed schedule of works to the first conversation is the single biggest thing that speeds up terms.

What does refurbishment bridging finance cost?

Pricing is set per month and depends on leverage, asset type, works intensity and your experience. Lower LTV and lighter works price better. The main costs are:

CostHow it is charged
Monthly interestOn the day-one advance from completion; on each works tranche from its drawdown date
Arrangement feeTypically around 1% to 2% of the loan, usually added to the facility
Exit feeSome lenders charge one, others do not; it affects total cost
ValuationRICS report covering current value and GDV
Monitoring surveyorInitial report plus a fee per inspection
Legal feesYour solicitor and the lender's solicitor

Interest is usually retained for the day-one advance and rolled up on works tranches, so you pay interest only on money actually drawn. Model the total in the bridging cost calculator and compare current pricing bands on our rates page.

Which exit strategies work for a refurbished commercial building?

The exit is what the lender is really underwriting. Common exits include:

Where the works include converting to flats, the planning route and exit are different; our commercial to residential conversion finance page covers that. Always build in time for letting voids or a slower sale, because the term must cover the works and the exit, not just the works.

Is a refurbishment bridge the right product, or is there a cheaper alternative?

A refurbishment bridge fits when the building is unmortgageable today, the works are defined and the value uplift is clear. It is not always the lowest-cost route. Alternatives worth considering:

Bridging is unregulated when the property is held for business or investment purposes. If anyone in your family will live in part of the building, the loan may be regulated and would go to a firm directly authorised by the Financial Conduct Authority, which we introduce. We are not directly authorised by the Financial Conduct Authority ourselves.

Unregulated commercial and investment bridging is arranged directly. Any case where the security includes a home you or an immediate family member occupies, including a flat above commercial premises, may be regulated and is introduced to a firm directly authorised by the Financial Conduct Authority. We are not directly authorised by the Financial Conduct Authority ourselves. Your property may be repossessed if you do not keep up repayments on a mortgage or any other debt secured on it.

Good questions, clear answers

Refurbishment bridging: questions answered

Ask about your situation
How much would a 200k bridging loan cost?

It depends on the monthly pricing, the term and the fees. The main costs are monthly interest, an arrangement fee of typically around 1% to 2% (for example £2,000 to £4,000 on £200,000), valuation, legal costs and on refurbishment loans the monitoring surveyor. Interest on works tranches only runs once drawn. Use our bridging cost calculator to model the total for your term.

What does Martin Lewis say about bridging loans?

We cannot speak for Martin Lewis or MoneySavingExpert, and consumer guidance is generally written for homeowners rather than businesses refurbishing commercial property. Our own view is practical: bridging is short-term, priced per month and only sensible with a costed works plan, contingency and a credible exit you can evidence before you borrow.

Is a bridging loan a good idea to buy a house?

This page covers commercial refurbishment. For buying a home you will live in, a bridge is a regulated mortgage contract and must be arranged by a firm directly authorised by the Financial Conduct Authority, which we can introduce. For commercial or investment property, a refurbishment bridge is a good idea when the building cannot be mortgaged until the works are done.

Is there a cheaper alternative to a bridging loan?

Sometimes. If the building is already lettable, a commercial mortgage with cash-funded works usually costs less. Heavy structural schemes may suit development finance. A second charge on another property or joint venture equity can also fill gaps. We compare the options against your timescale and exit before recommending a refurbishment bridge.

Can I get 100% of the refurbishment costs funded?

Some lenders will fund the full works cost, released in arrears in stages, provided the total facility stays within their cap on gross development value. The purchase deposit and the first stage of works usually still come from you, so you need some cash or additional security.

Do I need planning permission for a refurbishment bridge?

Light refurbishment usually does not need planning. Heavy works involving extensions, external alterations or change of use often do, and lenders will want consent in place before releasing works funds. If you are buying to obtain planning first, see our page on bridging for planning permission.

How long does refurbishment bridging finance last?

Terms run from 1 to 24 months, commonly 6 to 18 months on refurbishment. Choose a term that covers the works programme, a contingency for delay and the time needed to sell or let and refinance, because extending later is costly and not guaranteed.
