Office Finance UK
Office Finance UK
Office property sits at the more variable end of the commercial market, a single-let Grade A building in a regional city centre is a very different lending proposition from a multi-tenanted flexible workspace in a secondary location. Platinum Global Bridging Finance arranges office finance for owner-occupying businesses buying their own premises and for investors acquiring single-let or multi-let office buildings across the UK, through a panel of over 100 lenders. Facilities from £250,000 to £150m+. No broker fee on loans of £500,000 or above.
What Is Office Finance?
Office finance is commercial mortgage lending secured against office premises, available either as owner-occupied finance, where the borrowing business trades from the building, or as investment finance, where the office is let to one or more tenants. The same property could be financed either way depending on occupancy structure. Office property covers everything from a small professional services suite bought by its occupier, through to multi-floor city centre buildings let to corporate tenants, and increasingly, serviced and flexible workspace investments. Lenders active in this space range from mainstream high-street banks, who tend to favour simpler, well-let single-tenant buildings, through to specialist commercial lenders and challenger banks who are comfortable with multi-let, secondary, or transitional office stock that requires a more bespoke underwriting approach.
The UK office finance market in 2026 is more polarised than at any previous point. Prime, well-specified, EPC-compliant offices in major city centres attract genuine lender competition and competitive rates. Secondary offices, particularly those with poor energy credentials or in locations where occupier demand has weakened since the shift to hybrid working, face a narrower lender pool and higher pricing. Selecting the right lender for the specific asset is critical, approaching the wrong lender wastes time and, once a valuation fee has been paid, money.
Owner-Occupied vs Investment Office Finance
If your business will trade from the office, the loan is assessed against your trading accounts and adjusted net profit, following the same principles set out on our owner-occupied commercial mortgage page. Professional firms, solicitors, accountants, architects, and financial services businesses, are well-served by this market. Allica Bank is particularly active in the owner-occupied space for professional services firms. SIPP and SSAS pension fund structures are commonly used in the professional services sector to acquire office premises tax-efficiently, the pension fund purchases the building, charges the firm a market rent, and the rental income rolls up within the pension wrapper tax-free.
If the office is an investment asset, let to one or more tenants, the loan is assessed on the rental income and DSCR, as detailed on our commercial investment mortgages page. Lenders assess the lease profile, unexpired terms, tenant covenant quality, and the property’s location and marketability. InterBay and Shawbrook are active across the office investment spectrum from regional city centre assets to business park investments.
Office Market Context 2026
The UK office market has undergone significant structural change following the adoption of hybrid working patterns. Prime city-centre offices, high specification, well-located, EPC-compliant, continue to attract strong occupier demand and competitive mortgage terms. Occupier flight to quality is a defining feature of the 2026 market: businesses are downsizing their footprint but upgrading specification, concentrating demand into Grade A and refurbished Grade B stock in the best locations, while older, poorly specified buildings in secondary locations see values continue to soften.
Secondary and tertiary offices, particularly those with poor energy ratings (EPC D or below), face greater lender caution as both occupier demand and future regulatory requirements create asset risk. The trajectory toward mandatory minimum energy standards for let commercial property, EPC B required for new leases under current government proposals, means lenders are pricing in the cost of future improvement works when assessing sub-investment-grade office assets. For investors prepared to take on this risk, however, the repricing of secondary office stock has created genuine buying opportunities, particularly for buildings with realistic conversion or refurbishment potential.
Refinancing existing office debt, rather than new acquisition, is expected to be a defining feature of the 2026 commercial property market more broadly, as owners who fixed rates several years ago come to the end of their term and need to secure new terms against a repriced asset. Lenders increasingly want a clearer picture of long-term sustainability, compliance, and potential upgrade costs before approving finance on ageing office stock, so having environmental and EPC information ready at the outset materially speeds up the process.
Lenders increasingly factor in EPC ratings when assessing office investment loans. Properties with EPC A–C ratings attract the widest lender appetite and best rates. Properties rated D or below may face restricted LTV or higher pricing, and some lenders will require a costed refurbishment plan before advancing on a sub-investment-grade asset.
Serviced and Flexible Workspace
Serviced and flexible office investments, buildings let to an operator running short-term licences rather than conventional leases, are assessed differently from a standard multi-let office. Because income depends on the operator’s occupancy rates rather than a fixed contracted rent, some lenders treat these assets more like an operating business than a pure property investment, which affects both the loan sizing methodology and which lenders will consider the transaction. Where the operator has a strong track record and the building sits in a location with genuine flexible workspace demand, specialist lenders will still engage, but the lender pool is meaningfully smaller than for conventionally let office space, and terms typically reflect the additional operational risk.
Regional Office Markets
Office lending appetite varies significantly by location, and understanding the regional picture matters as much as the building itself. London remains the deepest and most liquid office market, with the widest lender pool for prime assets but the most acute divergence between prime and secondary pricing. Regional cities with strong occupier bases, Manchester, Birmingham, Leeds, Bristol, Edinburgh, have seen sustained investor and lender interest as businesses relocate functions out of London in search of lower occupancy costs, supporting values and lending appetite in well-located regional office stock. Smaller market towns and out-of-centre business parks see a materially narrower lender pool, particularly for secondary stock, and often require a specialist broker relationship to place successfully.
Alternative Use and Exit Strategy
Lenders on office assets, particularly secondary stock, increasingly factor in the building’s realistic alternative use if the current occupier were to vacate and re-letting proved difficult. A building with obvious residential conversion potential under permitted development rights, or one suited to healthcare, education, or leisure use, is viewed more favourably than a purpose-built specification office with few alternative uses in a location where office demand has structurally declined. This assessment sits alongside, rather than instead of, the standard income and covenant analysis, and is one of the reasons two offices of similar value and yield can attract materially different lender appetite.
Lending Criteria for Office Finance
| Parameter | Typical Range |
|---|---|
| Loan size | £250,000 to £150m+ |
| LTV (prime office) | Up to 75% |
| LTV (secondary/tertiary) | Up to 65% |
| Term | 3 to 25 years |
| Rate (2026) | 5.5% to 8.5% pa |
| DSCR (investment) | 125% to 150% of interest payment |
Fixed rates for prime office investment and owner-occupied transactions currently start from approximately 5.5% per annum for the strongest cases. Secondary office assets typically price from 7.0% to 8.5% pa. Owner-occupied professional services firms with strong DSCR and clean credit can often achieve rates toward the lower end of the owner-occupied range, particularly where the firm has an established relationship with its bankers and is approaching a challenger bank or specialist lender through an intermediary. Variable rate products are typically priced as a margin over the Bank of England base rate, so the headline rate moves with base rate changes over the term unless the borrower fixes.
What Lenders Look At on Office Assets
Beyond the headline DSCR and LTV, office lenders weigh location and transport links, building condition and EPC rating, tenant quality and unexpired lease length, and the realistic alternative-use potential of the building if the current occupier leaves. A well-located building in a strong commuter city with a single high-covenant tenant on a long lease is assessed very differently from a multi-let secondary building with a fragmented lease expiry profile, even where the two properties carry a similar valuation. Understanding how a specific lender will read a given building, rather than approaching the market generically, is where a specialist broker adds the most value on office transactions.
Car parking ratio, floor plate efficiency, and the flexibility of the internal layout also feed into how a valuer and a lender assess long-term marketability. A building with a deep, awkwardly shaped floor plate that cannot easily be subdivided for multiple smaller tenants is a weaker proposition than a building that can flex between single-tenant and multi-let configurations depending on market conditions. Similarly, buildings with generous car parking provision in locations outside the largest city centres, where public transport alternatives are more limited, tend to hold occupier demand better than equivalent buildings with restricted parking, and lenders factor this into their view of re-letting risk.
Worked Example: Professional Services Firm, Owner-Occupied
An accountancy practice with 12 years of trading history and £480,000 adjusted annual net profit purchases its city-centre office suite for £1,800,000.
- Purchase price: £1,800,000
- LTV: 65% = Loan of £1,170,000
- Rate: 5.75% pa fixed for 5 years (capital and interest, 20-year term)
- Monthly payment: approximately £8,190
- Current rent being paid: £9,500 per month
- Net saving versus renting: £1,310 per month, plus equity building over the term
- Arrangement fee: 1.5% = £17,550
No broker fee. Strong trading history and clean credit profile support competitive terms from Allica Bank or Shawbrook.
Worked Example: City Centre Office Investment
An investor acquires a fully let Grade B office building in Birmingham for £2,400,000. The building is multi-let to 4 tenants on leases ranging from 3 to 6 years at a combined passing rent of £168,000 per annum.
- Purchase price: £2,400,000
- LTV: 60% = Loan of £1,440,000
- Rate: 7.0% pa interest only
- Annual interest: £100,800
- Lender vacancy allowance (15%): adjusted income £142,800
- DSCR: £142,800 / £100,800 = 1.42x (above the 1.25x minimum)
- Arrangement fee: 1.5% = £21,600
- Deposit required: £960,000
No broker fee applies. The multi-let income spread and Birmingham city centre location support a competitive rate from a specialist office investment lender.
Worked Example: Refinancing a Secondary Office
An investor’s fixed rate on a secondary Grade B office in a regional town is coming to an end. The building was valued at £1,100,000 three years ago and is now valued at £980,000 following the wider market correction, but the building is fully let at £88,000 per annum.
- Current valuation: £980,000
- Existing loan balance: £660,000 (67% LTV against the new valuation)
- New rate: 7.25% pa interest only
- Annual interest: £47,850
- DSCR: £88,000 / £47,850 = 1.84x
- Outcome: refinance completes at the higher LTV band, but the strong DSCR and full occupancy support acceptance from a specialist lender comfortable with secondary office stock
This scenario, refinancing an asset that has fallen in value but retains strong income, is increasingly common in the 2026 office market and requires a lender genuinely active in secondary office refinancing rather than a generic approach to the whole market. Refinancing existing office debt is expected to lead activity across the wider commercial mortgage market in 2026 as owners who fixed rates during the lower-rate years reach the end of their term and need to secure new pricing against buildings that, in many cases, have moved in value since the original loan was arranged.
Office Bridging Loans
Where an office building requires refurbishment before it meets mainstream mortgage criteria, or where speed is required for an auction purchase, a commercial office bridging loan provides short-term funding to acquire and improve the asset. Once the works are complete and the building is let or lettable, we arrange the long-term office mortgage. For development of new office space or conversion of existing buildings to office use, commercial development finance is the appropriate product.
Permitted Development and Office Conversions
Permitted development rights allow certain commercial buildings, including many offices, to be converted to residential use without full planning permission. Where a borrower intends to convert an office building to residential, permitted development finance or permitted development bridging loans are more appropriate than a commercial office mortgage. We arrange finance for both the acquisition and conversion stages of these projects across the UK, which has become an increasingly common exit strategy for secondary office stock that no longer meets modern occupier expectations.
Frequently Asked Questions
Can I get an office mortgage for a serviced or flexible workspace investment?
Yes, but the lender pool is smaller. Serviced offices with short-term licences rather than formal leases are assessed differently from conventionally let offices. Some lenders treat them as operating businesses rather than pure property investments, which affects how the income is assessed and which lenders will consider the transaction.
What EPC rating do I need for an office mortgage?
Most mainstream lenders prefer EPC A–C. Properties rated D or below face restricted terms from some lenders, and from 2027 commercial properties let to new tenants will require at least an EPC B under current regulatory trajectory. We can advise on lenders who will finance sub-investment-grade assets alongside a costed refurbishment plan.
Can I buy an office building through my pension fund?
Yes, SIPP and SSAS pension funds can purchase commercial office property, including premises occupied by the pension holder’s own business. This is a specialist structure with significant tax advantages. We work with lenders experienced in SIPP/SSAS office mortgage lending.
What is the difference between Grade A and Grade B office finance?
Grade A offices, new-build or recently refurbished, high specification, EPC A or B, attract the most competitive mortgage terms and widest lender appetite. Grade B offices, older stock, functional but not premium, are financeable but at slightly higher rates. Grade C and below, or EPC D and lower, attract a narrower lender pool and require specialist placement.
Can I refinance an office that has fallen in value?
Yes, this is increasingly common. Lenders will look at the strength of the current income and occupancy rather than only the change in valuation, so a fully let building with a robust DSCR can often refinance successfully even where the capital value has softened since the original purchase.
How does hybrid working affect office mortgage lending?
Lenders now weigh occupier demand trends alongside the traditional income and covenant analysis. Buildings suited to the flight-to-quality trend, well-specified, well-located, strong EPC rating, continue to attract broad lender appetite. Older, poorly specified buildings in weaker locations face a narrower pool and more conservative terms, regardless of the current tenant’s covenant strength, because lenders are pricing in re-letting risk at the next lease event.
Does Platinum Global charge a broker fee for office finance?
No broker fee on facilities of £500,000 or above.
