How do I apply for a commercial mortgage?
13th February 2026
By Simon Carr
Applying for a commercial mortgage is significantly more complex than securing residential financing. It involves meticulous scrutiny of your business’s financial health, detailed projections, and a comprehensive valuation of the commercial property itself. Understanding this structured process is key to a successful application.
How Do I Apply for a Commercial Mortgage? A Step-by-Step UK Guide
Securing commercial property finance in the UK requires a rigorous, structured approach. Whether you are purchasing a factory, office block, retail unit, or investing in a mixed-use development, lenders need assurances regarding both the stability of your business and the viability of the asset itself. This detailed guide walks you through the essential steps, from initial preparation to final completion.
1. Preparation: Assessing Your Needs and Eligibility
Before approaching any lender, you must clearly define your financing needs and assess your ability to meet the rigorous eligibility criteria set by commercial mortgage providers.
Defining the Purpose and Property Type
Commercial mortgages cater to a wide variety of business needs. Your application strategy will depend heavily on the type of property you are acquiring and whether you intend to occupy it or rent it out as an investment (owner-occupied vs. commercial investment).
- Owner-Occupied Mortgage: You purchase a premises from which your business trades (e.g., a high street shop used by your own company).
- Commercial Investment Mortgage (Buy-to-Let): You purchase a property to rent out to other businesses, generating rental income.
Lenders view these types differently. Owner-occupied mortgages often rely on the profitability of your core business, while investment mortgages rely primarily on the strength of the existing or projected rental income.
Establishing Financial Viability and Deposit
Lenders typically require a substantial deposit for commercial loans, often ranging from 25% to 40% of the property value. Crucially, you must demonstrate affordability through a detailed business plan showing projected profits, cash flow, and historical performance (usually the last two to three years of accounts).
The lending decision revolves around the loan-to-value (LTV) ratio and the loan-to-income/rent (LTIR) ratio. If you are borrowing £300,000 for a £400,000 property, your LTV is 75%, meaning you need a 25% deposit (£100,000).
2. Understanding Commercial Mortgage Requirements
Commercial lenders have specific non-negotiable requirements related to the borrower, the business, and the security (the property). Meeting these upfront will significantly speed up your application.
Credit History and Financial Health
Both your personal and business credit history will be thoroughly examined. Any defaults, County Court Judgments (CCJs), or history of poor financial management will complicate the application or lead to significantly higher interest rates. Lenders look for stability and a pattern of responsible borrowing.

Business Experience and Trading History
While some lenders may consider start-ups, a robust trading history of at least two to three years is typically preferred. Lenders want to see consistent profit and revenue growth. Furthermore, the directors or partners involved often need relevant experience operating a similar business or managing commercial property investments.
If the business is new or relies heavily on future contracts, the lender may require additional security, such as personal guarantees from the directors, meaning their personal assets are secured against the business debt.
3. Gathering Essential Documentation
The complexity of commercial applications demands extensive documentation. Having these documents prepared and professionally organised is critical before making an initial approach.
Required Business Documentation
- Full Business Plan: Detailing market analysis, management structure, operational strategy, and clear projections for profitability over the loan term.
- Audited Accounts: Usually covering the last three years of trading history.
- Management Accounts: Current period accounts (if recent audited accounts are unavailable).
- Cash Flow Forecasts: Detailed projections showing how the business will service the debt, including worst-case scenario analysis.
- VAT Returns: Proof of consistent and substantial turnover.
- Company Information: Certificate of incorporation, Memorandum and Articles of Association.
Required Personal and Property Documentation
- Personal Financial Statements: Including details of assets, liabilities, and existing mortgage statements for key individuals.
- Proof of Identity and Address: Passport or driving licence, and recent utility bills.
- Property Details: Full address, tenure (freehold or leasehold), floor plans, existing EPC (Energy Performance Certificate), and any current tenancy agreements (if applicable).
- Source of Deposit: Documentation verifying the origin of your funds to comply with Anti-Money Laundering (AML) regulations.
4. The Application Process: Choosing Your Lender
Once you have compiled your documentation and verified your eligibility, the next step is formally applying for the finance.
Broker vs. Direct Application
Given the specialist nature of commercial lending, most applicants choose to work with a commercial mortgage broker. Brokers have access to a wider panel of specialist lenders (including high street banks, challenger banks, and private funds) and understand the specific underwriting criteria of each. This is crucial because standard high street requirements often exclude properties deemed “specialist” or businesses with unique trading patterns.
If you apply directly to a high street bank, you risk lengthy delays and potential rejection if your case does not fit their narrow, standard criteria.
Obtaining an Agreement in Principle (AIP)
The first formal step is receiving an Agreement in Principle (AIP) or Head of Terms. This document is issued after the lender reviews your initial application, high-level financials, and credit profile. It confirms the lender is willing, in principle, to lend the requested amount based on the information provided, subject to due diligence, valuation, and legal checks.
The AIP is not a binding loan offer, but it is an essential document that proves to property vendors and estate agents that you are a serious buyer with pre-arranged finance.
5. Underwriting, Valuation, and Due Diligence
After receiving an AIP, the application moves into the detailed underwriting phase, where the lender verifies every piece of information and assesses the physical security.
The Commercial Valuation Survey
A crucial step is the independent valuation of the commercial property, which you will typically be required to pay for. Unlike residential valuations, commercial surveys are highly detailed. They assess not only the bricks and mortar value but also the property’s viability based on its current use, rental yield potential, and market demand for similar properties in the area.
- If the property is owner-occupied, the valuer assesses its potential alternative use should the business fail.
- If it is an investment property, the valuation will focus heavily on the achievable rental income and yield, often using capitalisation rates specific to that commercial sector.
Detailed Underwriting and Due Diligence
The underwriting team will scrutinise your financial documents, cross-referencing your business plan projections against historic performance. They use complex modelling to stress-test your business’s ability to withstand economic downturns or periods of reduced trade while still meeting the mortgage obligations.
If you are applying for a substantial loan or if the property is unique (e.g., a hotel or nursing home), the lender may require additional interviews with the directors or site visits to verify operations.
Legal Process and Conveyancing
Once the valuation is satisfactory, the formal offer is issued. At this stage, legal representatives (solicitors) for both the borrower and the lender become heavily involved in the conveyancing process. Commercial conveyancing is intricate and includes:
- Reviewing the property title and local search results.
- Examining planning permissions and adherence to building regulations.
- Negotiating and agreeing on the specific terms and conditions of the mortgage deed.
Due to the complexity, the legal phase can often be the longest part of the application, sometimes taking several weeks or months.
6. Finalising the Loan and Key Risks
The final step involves the legal completion and draw-down of funds. However, before signing the facility agreement, it is vital to fully comprehend the commitments and potential risks involved with commercial finance.
Understanding Interest Rate Structures
Commercial mortgages typically offer either fixed rates (where the interest rate remains constant for an agreed period) or variable/tracker rates (which fluctuate, often pegged to the Bank of England Base Rate or a lender’s specific cost of funds). Variable rates can offer lower initial payments but carry the risk that repayments could increase significantly if rates rise.
The Importance of Compliance and Risk Management
Commercial mortgages are secured debt. Failure to maintain repayments has severe implications for the borrower and any guarantors. Unlike some residential mortgages, the regulatory protection available under the Financial Conduct Authority (FCA) is usually much less comprehensive for commercial contracts.
Lenders impose strict covenants (conditions) that must be adhered to throughout the loan term, such as maintaining specific financial ratios (e.g., interest coverage ratio). Breaching these covenants, even without missing a payment, can trigger a default clause.
Risk Warning: If you secure the loan against your business property or, in some cases, your residential property (via a personal guarantee), your property may be at risk if repayments are not made. Consequences of default can include legal action, the imposition of significantly increased interest rates, additional charges, and ultimately, repossession of the secured asset by the lender to recover the outstanding debt.

People also asked
What is the typical commercial mortgage interest rate?
Commercial mortgage interest rates are highly specific to the risk profile of the business, the property type, and the LTV ratio. They are generally higher than residential rates, often ranging from 4% to 8% above the Bank of England Base Rate, depending on current market conditions and lender fees.
How long does a commercial mortgage application take?
The application process is variable, but typically takes between three and six months from initial enquiry to completion. Complex cases involving specialist properties, complex legal searches, or poor financial history can often extend this timeline considerably.
Can I get a commercial mortgage with bad credit?
While challenging, obtaining a commercial mortgage with bad credit is possible, especially if the business itself is strong and profitable. Specialist commercial lenders may consider applications, but they will likely require a higher deposit (LTV will be lower) and charge a significantly higher interest rate to mitigate the increased perceived risk.
What is the minimum deposit required for a commercial mortgage?
The minimum deposit required is usually 25% of the property purchase price. However, for properties deemed higher risk (such as hotels, public houses, or properties requiring extensive refurbishment) or for applications with weaker financial documentation, lenders may require a deposit of 35% or even 40%.
Can a commercial property be residential?
Properties designed for commercial use cannot generally be used residentially without formal change of use planning permission from the local authority. Lenders will fund mixed-use properties (e.g., shop with a flat above), but the application is assessed using a blended commercial and residential lending criteria.
Next Steps in Your Commercial Mortgage Application
To successfully navigate the complexities of securing commercial finance, focus on meticulous preparation. Ensure your business financials are accurate and up-to-date, your business plan is robust, and you have sought advice from experienced professionals, such as a commercial mortgage broker and a solicitor specialising in commercial property law.
Remember that the financial commitment is substantial, and understanding the terms and conditions of the loan, including all potential penalties and fees, is essential before committing to the facility agreement.
