Bridging loan for office property:let, vacant and conversion
A bridging loan for office property is short-term, interest-only finance secured on an office building that lets you buy, refinance or reposition it quickly, then repay from a sale, a refinance once the space is let, or a conversion exit. We arrange office bridging finance for investors, owner-occupiers and developers across England and Wales through a wide panel of bridging lenders, from specialist lenders to private credit funds.
Offices are no longer a single asset class in a lender's eyes. A well-let, energy-efficient building in a strong location is treated very differently from a dated, half-empty block on a business park. This page explains how lenders separate the two, what that does to valuation, LTV and appetite, and how to set up an exit they will believe.
Key takeaways
Lenders value offices on what they are today: investment value if let, vacant possession value if empty.
Well-let office stock can support LTV up to 70% to 75%; vacancy, secondary locations and poor condition reduce it.
Break clauses, lease length and EPC rating all affect both value and the credibility of a refinance exit.
Class MA conversion potential supports the exit, but the day-one loan is based on current office value.
Office bridging is unregulated unless part of the security is, or will be, your family home.

How do bridging lenders value an office building now?
Since 2020, hybrid working has changed how valuers and lenders read office demand. Prime, efficient space has held up far better than older secondary stock, and valuers now look much harder at letting evidence, void periods and the cost of bringing a building up to standard. The valuation basis a lender uses depends on the state of the building on the day you complete.
Office scenario
Valuation basis lenders use
Lender appetite
Fully let to established tenants
Investment value, driven by rent, lease length and covenant
Strong, LTV towards the top of the commercial range
Multi-let, partly vacant
Investment value on the let income plus a view on the voids
Good, LTV moderated for vacancy
Fully vacant
Vacant possession value, often with a 90 or 180-day assumption
Selective, lower LTV, exit scrutinised
Conversion candidate (Class MA or full planning)
Current value as offices; GDV considered only for the exit
Available, lower LTV unless consent is in place
Dated stock with a poor EPC
Value reduced by refurbishment and compliance cost
Case by case, works budget required
The key point: the lender lends against what the building is worth today, not what it will be worth once let or converted. Your business plan matters, but it drives the exit assessment, not the day-one loan.
What LTV can you expect on a bridging loan for office property?
On a first charge, office bridging finance commonly runs up to 70% to 75% loan to value for standard commercial property that is let or easily lettable. Each step away from that profile tends to pull the LTV down:
Vacancy: a vacant office is valued on vacant possession, and lenders typically lend a lower percentage of that lower figure.
Location: out-of-town and secondary market offices usually attract more conservative terms than central, well-connected buildings.
Specification: buildings needing new heating, cooling, lifts or a full strip-out carry more risk.
Second charge: bridging behind an existing mortgage is assessed on combined LTV and is usually lower again.
If the deposit is the constraint, additional security over another property can bridge the gap. Run the numbers first with our LTV calculator, and see our wider guide to commercial bridging loan LTV for gross and net loan calculations.
Which lease and tenancy points will the lender check?
When you apply for a bridging loan for office investment, the lease is the asset. The valuer and the lender's solicitor will read every lease and the tenancy schedule, and the following points move both value and appetite:
Tenant covenant: the financial strength of each occupier. A PLC or public body reads very differently from a start-up on a short licence.
Unexpired term and break clauses: a tenant break falling inside the loan term is a direct risk to a refinance exit.
Security of tenure: whether leases are inside or contracted out of the Landlord and Tenant Act 1954, which affects your ability to obtain vacant possession for a conversion.
Rent arrears and service charge: arrears, disputes and unrecovered service charge on a multi-let building are flagged early.
Serviced and flexible space: income from short licences or a serviced office operator is often valued more cautiously than conventional leases.
Bring the tenancy schedule, copies of leases and any rent deposit deeds to the first conversation. It saves time at valuation.

How do EPC ratings, condition and planning affect an office deal?
Energy performance is now a lending issue as much as a letting one. Under the Minimum Energy Efficiency Standards, landlords in England and Wales cannot continue to let most non-domestic property with an EPC rating below E unless an exemption is registered, and the government has consulted on raising that threshold. A low rating can block a letting exit and reduce value, so lenders ask for the EPC and, where it is weak, a costed improvement plan.
Condition matters too. Expect questions about the asbestos register and management survey, the age of the heating, ventilation and lifts, the roof and the fire strategy. Where works are needed, a refurbishment bridging loan can fund the purchase and the works in one facility.
Planning drives the conversion story.
Class MA permitted development in England allows change of use from Class E to residential via prior approval, provided the building has been in Class E use for at least two continuous years. Prior approval covers transport, contamination, flooding, noise, natural light, fire safety and related matters, and listed buildings are excluded.
Lenders will fund the purchase on current office value; the residential value supports the exit. Our page on office to residential conversion finance covers that route in depth. Confirm the planning position with a planning consultant before you commit.
Common office bridging deals and the exits lenders accept
Completion is usually due within 28 days, too fast for a term lender
Commercial mortgage or sale
Buying a vacant or under-let office to re-let
Mortgage lenders want income in place before they lend
Commercial investment mortgage once leases are signed
Owner-occupier buying its own premises quickly
Secures the building while the trading business arranges term finance
Owner-occupier commercial mortgage
Office bought for Class MA or full planning conversion
Purchase moves before prior approval or works funding is ready
Development finance, then sale or refinance of flats
Capital raise on an unencumbered office
Fast release of equity for another purchase or business need
Refinance, sale or the other transaction completing
Whatever the deal, the exit strategy needs evidence: a decision in principle from a term lender, comparable lettings, an agent's marketing advice, or a credible sales appraisal. Our guide to bridging loan exit strategies sets out what each route needs.
How is an office bridging loan priced and structured?
A bridging loan for office purchases is priced as monthly interest, and the main levers on price are LTV, the quality of the building and the strength of the exit. Lower LTV on a let building generally prices better than high LTV on a vacant one. Costs to budget for:
Arrangement fee: typically around 1% to 2% of the loan, usually added to the facility.
Interest: retained interest (deducted upfront for the term), rolled up interest (added monthly and repaid at the end) or serviced interest (paid monthly from rent).
Exit fee: charged by some lenders, not all. We point it out in every comparison.
Valuation and legal fees: a RICS valuation instructed by the lender and both solicitors' costs.
Most office purchases sit in a limited company or SPV, and lenders normally ask for personal guarantees from the directors. Where rent is coming in, serviced interest can reduce the gross loan. Model the total cost with the bridging cost calculator.
Is office bridging regulated?
Bridging secured on an office held for investment or business purposes is unregulated, and we arrange it directly. The position can change if you or an immediate family member will live in the building, for example in a flat within an office building. The loan may then be a regulated mortgage contract, and we introduce those cases to a firm directly authorised by the Financial Conduct Authority.
We are not directly authorised by the Financial Conduct Authority ourselves.
How to prepare an office bridging application
Property pack: address, floor areas, EPC, tenancy schedule, leases and any asbestos or condition reports.
Purchase details: price, deposit source, completion deadline and the agent or auctioneer's details.
Exit evidence: term lender appetite, letting agent advice, planning status or a sales appraisal.
Borrower details: company structure, directors, assets and liabilities, and any credit history issues disclosed upfront.
With that in hand, a lender can issue terms on a bridging loan for office space quickly and instruct the valuation. Completion can take two to four weeks where valuation and legal work move quickly. See how it works for each stage.
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.
A bridge loan is short-term secured finance, usually for 1 to 24 months, that covers a gap between needing money now and a longer-term source of repayment arriving later. On an office, that gap is often the time between buying the building and letting it, selling it or refinancing onto a commercial mortgage. Interest is charged monthly and the loan is repaid in one sum at the end.
Which companies do bridging loans?
Bridging finance comes from specialist bridging lenders, challenger and specialist banks, private credit funds and some family offices. Their appetite for offices varies widely, especially for vacant or secondary buildings. As a broker, we compare them for each case. Our commercial bridging lenders page explains how the different lender types approach office and other commercial property.
What were COVID loans?
COVID loans were government-backed schemes launched in 2020 to support businesses through the pandemic, mainly the Bounce Back Loan Scheme and the Coronavirus Business Interruption Loan Schemes, delivered through accredited lenders. They are closed to new applications. If your business still has one outstanding, a bridging lender will treat it as existing debt and ask about repayments as part of its checks.
What are the different types of business loans?
The main types are unsecured business loans, secured term loans, commercial mortgages, asset finance, invoice finance, revolving credit facilities and bridging loans. For buying or refinancing an office building quickly, a bridging loan or commercial mortgage is usually the right fit, because both are secured on the property and sized to its value rather than to turnover alone.
Can I get a bridging loan on a vacant office?
Yes. Vacant buildings are one of the main reasons investors take a bridging loan for office stock, because most mortgage lenders want income in place. The lender values the building on vacant possession, lends a lower percentage than on let stock and looks closely at the exit, whether that is letting and refinancing, selling, or converting under Class MA or full planning permission.
Does a poor EPC rating stop office bridging finance?
Not necessarily, but it affects the deal. A rating below E can prevent you from letting the space without an exemption, which weakens a letting exit and reduces value. Lenders will usually want to see the cost of improvement works in your plan, and may fund those works as part of a refurbishment bridge.
