Commercial mortgage FAQ (UK)

Commercial mortgages are used to finance business property and property investment. They can support a wide range of objectives, from buying premises and refinancing existing loans to funding expansion and investment strategies.

Because commercial lending is assessed differently to residential borrowing, it helps to understand what lenders look for and how the process typically works.

What is a commercial mortgage?

A commercial mortgage is a loan secured against a commercial property. The property may be used for business purposes (for example, offices, retail units, warehouses, or mixed-use buildings) or held as an investment.

In most cases, lenders assess:

• the value and characteristics of the property
• the borrower’s ability to make repayments (often through cashflow and financial evidence)
• the overall risk of the deal, including the proposed loan structure

Can I use a commercial mortgage to buy premises for my business?

Yes. Commercial mortgages can be used to purchase business premises.

Lenders typically consider whether the business can generate sufficient income to service the debt, alongside the property’s valuation and the income it can support (for example, where the property is let or has rental potential).

Is it possible to refinance a commercial property?

Refinancing is a common reason to take out a commercial mortgage.

It may be used to:

• replace an existing facility
• restructure repayments
• release equity (where appropriate)
• fund improvements or changes to the property

Refinancing outcomes depend on the current loan position, the property’s value, and the borrower’s financial profile.

How hard is it to get a commercial mortgage?

Commercial lending can be more complex than residential lending because underwriting often involves a broader set of considerations.

Whether a lender is willing to proceed usually depends on a combination of factors, such as:

• the property type, condition, and valuation
• the property’s rental/cashflow potential (where relevant)
• the borrower’s financial information and history
• the strength of the business plan (where the lender requires it)
• the proposed loan term and repayment approach

Clear, consistent information can help reduce avoidable delays.

How much deposit do I need?

Deposit requirements vary by lender, property type, and the overall risk profile of the deal.

In practice, commercial mortgages often require a larger deposit than many residential products. Deposit level is commonly influenced by:

• the loan-to-value (LTV) the lender is prepared to support
• whether the property is owner-occupied or let
• the borrower’s financial strength
• the valuation and the income potential of the property

Are commercial mortgages more expensive than residential mortgages?

Commercial borrowing can be priced differently to residential borrowing.

Costs may reflect the perceived risk of the property and the way the loan is assessed. Commercial deals can also involve additional costs during the process, such as valuation and legal fees.

Can I deduct mortgage interest against tax for a commercial property?

Tax treatment depends on your circumstances and the structure of the investment or business.

In some cases, interest costs may be eligible for relief, but the rules can be complex and fact-specific. For tax matters, it’s usually important to consider your position with a qualified tax adviser.

Can I get a residential mortgage on a commercial property?

In most cases, residential mortgages are not intended for properties that are genuinely commercial.

However, some properties may have mixed use (for example, where part of the building is used as a home and part is used for business). Whether a lender will consider a mixed-use property depends on how it is used and how it is valued.

Are commercial mortgages regulated?

Regulation can depend on how the mortgage is arranged and who the borrower is.

Some commercial mortgages may be arranged in the name of a limited company and may not fall under the same consumer mortgage regulation framework as residential lending. Where a mortgage is arranged in an individual’s name, different regulatory considerations may apply.

It’s also worth noting that the Financial Conduct Authority does not regulate some forms of buy-to-let mortgages and commercial mortgages, but does regulate bridging loans.

What documents are usually needed for a commercial mortgage application?

Requirements vary by lender and deal type, but applications commonly involve evidence such as:

• business accounts (where applicable)
• personal financial information (where relevant)
• details of the property and intended use
• rental information (if the property is let)
• business plans or projections (where required)
• identification and legal information

Providing clear, consistent information can help keep the application moving.

How long does the commercial mortgage process take?

Timelines vary depending on lender workload, the complexity of the case, and how quickly information is provided.

The process often includes valuation, underwriting, and legal steps. Delays can occur if documentation is incomplete, if the valuation raises questions, or if further investigation is needed.

What factors affect whether a lender will lend?

Commercial lenders typically focus on both the property and the borrower.

Common factors include:

• property valuation and condition
• whether the property is owner-occupied or let
• lease terms and rental strength (where applicable)
• borrower cashflow and financial resilience
• credit history and existing commitments
• the proposed loan structure (term, repayment type, and security)

What types of commercial finance are there?

Commercial finance can include several different product categories, depending on the purpose of the funding.

Common examples include:

• Commercial mortgages for buying or refinancing commercial property
• Bridging loans for short-term funding needs
• Development finance for construction or major renovation projects

The most suitable option depends on the timeline, the nature of the project, and how lenders assess risk.

Is a commercial mortgage the right choice for every business?

Not necessarily.

Commercial mortgages are often suitable where there is a clear property value and a credible plan for servicing the debt over the agreed term.

For some situations—such as short-term timing gaps or projects with different risk profiles—other forms of finance may be more appropriate.
