Commercial Mortgages: Investing in Commercial Property Through Lending

Commercial property — offices, retail premises, industrial warehouses, mixed-use buildings, and specialist sectors like healthcare or leisure — offers UK investors an alternative to the residential buy-to-let market. Commercial property typically delivers higher yields (the gross rental yield as a percentage of the purchase price) than residential, reflects different economic drivers, and has different legal and financing characteristics.

The financing vehicle is the commercial mortgage: a loan secured against a non-residential property, typically to a company borrower, repaid from rental income and ultimately from a sale. Understanding how commercial mortgages differ from residential, which lenders are active, and how the different property sectors are assessed is the foundation for informed commercial property investment.

Important: Commercial property values, rental yields, and lender criteria are highly variable and change with economic conditions. Always seek independent financial and legal advice before investing. Commercial property investment involves significant capital at risk.

What Is a Commercial Mortgage?

A commercial mortgage is a loan secured against commercial (non-residential) property. The category is broad:

• Standard commercial: offices, retail units, industrial/warehouse units, mixed-use (ground floor commercial, upper floor residential)
• Semi-commercial: properties with both residential and commercial elements
• HMO (Houses in Multiple Occupation) with 7+ units: regulated differently from standard residential BTL; treated as commercial by many lenders
• Licensed premises: pubs, hotels, restaurants (specialist sub-category)
• Agricultural and specialist: farms, care homes, student accommodation, car parks (further specialist categories)

The borrower is typically a limited company (commercial mortgages can be taken in personal names but this is less common, particularly for investment properties). The lender's primary security is the property; the lender will also typically take personal guarantees from company directors.

The Commercial Mortgage Lender Market

The commercial mortgage market is divided between the clearing banks (relationship-based, larger loans) and specialist lenders (broader criteria, more accessible, often higher rates).

The Clearing Banks

Lloyds Commercial Banking, HSBC Commercial, Barclays Business — all offer commercial mortgages, typically starting from £250,000 to £500,000 in loan amount. The clearing banks favour established businesses with existing banking relationships, strong track records, and well-tenanted properties in prime locations. They are generally not the right starting point for a new investor buying a first commercial property.

Handelsbanken: The Swedish-owned bank with a distinctive decentralised model — each branch has genuine lending authority, and decisions are made locally by branch managers who know the customer and the local market. This makes Handelsbanken particularly effective for SME commercial property lending where the borrower has a strong local story to tell. Minimum loan typically £500,000+.

Specialist Commercial Lenders

Cambridge & Counties Bank: Focused on commercial investment property. Known for accessibility and relatively streamlined processes.

Aldermore Bank: Established specialist in SME and commercial property lending. Offers commercial mortgages from approximately £75,000+.

Paragon Bank Commercial: One of the UK's largest specialist lenders; commercial property is a core product alongside BTL.

Shawbrook Bank: Specialist lender with strong commercial property and bridging products. Particularly active in complex commercial transactions.

Precise Mortgages / Kent Reliance (OSB Group): Active in commercial and semi-commercial mortgage lending.

Atom Bank: Digital challenger bank with commercial mortgage products targeting SME borrowers.

Key Commercial Mortgage Terms

Loan-to-Value (LTV)

Commercial LTV is typically lower than residential:

• Standard commercial (offices, good-quality retail, industrial): 65-75% LTV
• Retail (standard): 55-65% LTV (reflecting the structural challenges facing physical retail)
• Licensed premises: 50-60% LTV (more specialist, higher risk)
• Semi-commercial: 65-70% LTV

This means a commercial property investor typically needs a deposit of 25-35% — more for challenged retail.

Interest Rates

Commercial mortgage rates are higher than residential rates, reflecting the perceived higher risk:

• Clearing bank commercial rates: currently approximately 1.5-3% above base rate for strong credits.
• Specialist lender commercial rates: approximately 2-4.5% above base rate, depending on property type, tenant quality, and borrower strength.

Rates are typically variable (base rate plus a margin) on commercial mortgages, more so than residential. Fixed rate commercial terms are available but less common, particularly for longer periods.

The Stress Test

Lenders apply a stress test to commercial mortgage applications: can the borrower service the debt if interest rates rise by 2-3% above the current rate? A property with rental income that barely covers current payments will fail the stress test and the maximum loan will be reduced accordingly.

Term and Amortisation

Commercial mortgage terms typically range from 5 to 25 years. Unlike residential mortgages (which almost always fully amortise over the term), commercial mortgages more commonly offer:

• Interest-only during the term, with a balloon payment (the full principal) at maturity
• Partial capital repayment with a balloon
• Full amortisation (capital and interest throughout)

Interest-only commercial mortgages are more common in the investment property sector (where the borrower intends to sell the property at term to repay the principal, rather than paying down the mortgage from rental income).

The Rental Yield Coverage Requirement

The primary affordability test for a commercial investment mortgage is yield coverage: the annual rental income must cover the annual mortgage interest by a sufficient margin.

Most commercial lenders require rental income to cover 125% to 150% of mortgage interest at a stressed rate. For a property with a 6% net yield:

• Property value: £500,000
• Annual net rent: £30,000
• Maximum annual mortgage interest at 125% coverage: £24,000
• Maximum loan at 6% stressed interest rate: £400,000 (80% LTV) — but LTV cap would likely restrict this to 70-75%

Tenant quality matters: A property let to a single-tenant FTSE 100 company on a 10-year lease with upward-only rent reviews is valued differently from a property let to a small local business on a 3-year lease with no break clause. The lender will want to see lease terms, and the tenant's covenant strength (financial stability) influences both the valuation and the LTV they will lend against.

Vacant possession risk: If the property is currently vacant, obtaining an investment commercial mortgage is difficult. Lenders typically lend on the basis of existing income. A vacant building may require a commercial development or bridging loan until a tenant is secured.

Commercial Property Valuation Methods

A commercial property is valued by a RICS-qualified surveyor using one or more of three methods:

The Investment Method

The most common method for income-producing commercial property. The annual passing rent is capitalised at the appropriate yield (capitalisation rate) for the property type, location, and lease terms.

Value = Annual Rent ÷ Yield

Example: a warehouse let at £80,000/year in a prime logistics location where similar properties trade at 5% yield: Value = £80,000 ÷ 0.05 = £1,600,000.

The yield reflects market conditions — where investor demand is high (logistics and industrial in 2021-22), yields compressed to record lows, driving values up. Where investor demand is weak (high street retail from 2018-2022), yields expanded, driving values down.

The Comparable Sales Method

For properties where there is a sufficient volume of comparable transactions, valuers reference recent sales of similar properties in the same location.

The Depreciated Replacement Cost Method

For specialist buildings where there is no active rental or sales market (a purpose-built manufacturing facility, a specialist research lab), the valuer estimates the cost to replace the building (new build cost less depreciation) as a proxy for value.

The Sector Investment Case

Industrial and Logistics

The best-performing major commercial property sector over the 2018-2026 period. Drivers: e-commerce demand for distribution space, reshoring of supply chains post-COVID and post-Ukraine, the growth of urban logistics (last-mile delivery). Prime logistics yields are low (reflecting strong demand), but good rental growth has partially compensated. Secondary industrial (smaller units, older stock in regional locations) offers higher yields with acceptable tenant demand from SME occupiers.

Retail

Structurally challenged. High street vacancy rates remain elevated in many UK towns. However, prime retail in dominant locations (major city centres, key retail parks) has shown recovery — yield expansion has been substantial, offering value to investors able to tolerate the risk and hold through a cycle. Supermarket-anchored retail has shown resilience. Out-of-town retail parks have performed better than high street.

Offices

The post-COVID market has bifurcated sharply. Prime, city-centre, highly amenitised ("Grade A") offices are in strong demand — occupiers are consolidating into smaller, better-quality space to attract hybrid workers. Secondary offices (older stock, suburban, poor amenity) face chronic vacancy and obsolescence risk. ESG requirements are accelerating the devaluation of poorly-rated office stock.

Mixed-Use

Commercial ground floor (retail or F&B use) with residential above. The residential component provides a more resilient income base if the commercial element is vacant. Lenders treat mixed-use at a slightly lower LTV than pure residential but it remains accessible.

Alternative Sectors

Healthcare (GP surgeries, dental practices, care homes), student accommodation, car parks, and self-storage offer attractive yields and often long, secure leases. These are specialist sectors requiring specific expertise in operations and valuation. Private equity and institutional investors have driven yield compression in the best assets; secondary and regional assets still offer accessible entry points.
