What should I include in my commercial property mortgage proposal?
13th February 2026
By Steve Walker
Lenders treat commercial property mortgage applications as a combination of personal borrowing risk and business investment viability. A robust proposal must meticulously detail the borrower’s financial stability, the performance and projections of the business occupying or managing the property, and the value and condition of the security asset itself. Success hinges on clear, complete, and professionally presented documentation that answers every potential risk question proactively.
Understanding What Should I Include in My Commercial Property Mortgage Proposal?
Securing a commercial property mortgage in the UK is significantly more complex than obtaining a standard residential loan. Lenders are taking on a greater risk, as commercial income streams can be volatile and the underlying asset value is often tied directly to the business performance or economic conditions within a specific sector.
Your mortgage proposal is your primary opportunity to demonstrate that this risk is acceptable, manageable, and profitable for the lender. It serves as a comprehensive dossier detailing your finances, your business strategy, and the quality of the security you are offering. Failure to provide complete or accurate information is the most common reason proposals are rejected or significantly delayed.
The Foundation: Why Lenders Require Extensive Documentation
Lenders need to answer two fundamental questions before approving any commercial finance:
- Serviceability: Can the borrower/business generate sufficient, consistent cash flow to cover the mortgage repayments (interest and capital)?
- Security: If the borrower defaults, is the property valuable enough and marketable enough to recoup the loan principal and associated costs?
To satisfy these concerns, your commercial property mortgage proposal must be structured around three critical pillars: the Borrower, the Business, and the Property.
Pillar 1: Financial Standing of the Borrower and Directors
Even if the mortgage is held by a limited company, lenders almost always require detailed financial information on the company’s directors and key shareholders. This often involves providing Personal Guarantees (PGs), meaning the directors’ personal assets could be pursued if the business defaults.
Personal Financial Documentation Required
Lenders need to gauge the personal stability and existing commitments of the individuals responsible for the loan:
- Personal Asset and Liability Statement: A schedule detailing all personal assets (e.g., residential property, investments, savings) and liabilities (e.g., residential mortgages, loans, credit card debt).
- Proof of Identity and Address: Standard documentation such as passport/driving licence and recent utility bills.
- Personal Bank Statements: Typically covering the last three to six months to show income consistency and expenditure patterns.
- Credit History Report: Lenders will run their own searches, but providing a clear, accurate personal credit file upfront can expedite the process and allow you to address any anomalies.
Understanding your personal credit profile is essential, as poor credit scores, defaults, or county court judgments (CCJs) can severely impact the terms offered or lead to rejection.

Pillar 2: The Business Plan and Financial Viability
This is arguably the most crucial section for owner-occupier mortgages or investment proposals where the rental income relies heavily on a single tenant (your business). Lenders need concrete proof that the business is sustainable and has a clear path to generating the required income.
Required Business Financial Documentation
- Historical Trading Accounts: Lenders typically require the last three years of audited or management accounts (Profit and Loss statements, Balance Sheets). They will scrutinise trends in turnover, profit margins, and overheads.
- Cash Flow Forecasts: A detailed projection (usually 12–24 months) showing expected income and expenditure, proving the business can comfortably meet the new mortgage repayments, even during potential quiet periods or unexpected costs.
- Management Information (MI): Recent, accurate monthly or quarterly accounts if the latest statutory accounts are several months old.
- Tax Returns: Corporation Tax returns and VAT returns, demonstrating compliance and confirming reported income figures.
- Organisational Structure: Documents detailing the legal structure (e.g., Limited Company, LLP, Sole Trader), Articles of Association, and Confirmation Statement (CS01).
The Written Business Plan
Beyond the numbers, you must provide a persuasive narrative. The business plan should clearly outline:
- Executive Summary: A brief overview of the business, its track record, and the purpose of the mortgage.
- Market Analysis: Detailed information on the industry, target market, competitive advantages, and the economic landscape. Lenders want reassurance that the business is robust against market fluctuations.
- Management Team: CVs and professional histories of the key management personnel, highlighting relevant experience.
- Financial Projections: Explanation of the assumptions used in your cash flow forecasts and how the new property acquisition or refinancing will positively impact the business’s profitability and growth.
For UK businesses seeking guidance on financial management and planning, consulting resources like the government-backed MoneyHelper service for business debt advice can be helpful in ensuring sound financial governance before submitting your proposal.
Pillar 3: The Security Asset (The Commercial Property)
The property itself acts as the primary security for the loan. Lenders need extensive documentation to confirm its value, legal status, condition, and marketability.
Property-Specific Documentation
- Property Details: Full address, size (square footage or metres), type of use (e.g., Class E, Industrial, Retail), and site plan.
- Valuation Report: The lender will commission an independent valuation conducted by a surveyor from their approved panel. However, providing any existing recent valuations or purchase price documentation is helpful for initial assessment.
- Building Survey: Depending on the age and type of the building, a structural survey may be required to identify potential defects that could reduce its value or lead to expensive repair costs soon after purchase.
- Energy Performance Certificate (EPC): Mandatory documentation showing the building’s energy efficiency rating, which is increasingly important for commercial assets in the UK.
- Title Deeds and Legal Documentation: Proof of ownership (or the ability to obtain it), including any restrictive covenants, easements, or existing charges on the land.
- Insurance Documentation: Evidence of adequate buildings insurance that covers the lender’s interest in the property upon completion.
Investment Property Specifics
If the commercial mortgage is for an investment property (where the borrower lets the property to third-party tenants), the documentation requirements expand to focus on rental income:
- Tenancy Agreements/Leases: Copies of existing leases, detailing rental income, lease length, break clauses, and repairing covenants. The quality and longevity of the tenancy are critical factors in the lender’s assessment of rental yield.
- Schedule of Rents: A detailed breakdown of current rents received and service charges, confirming the accuracy of projected rental yield calculations.
- Yield Calculations: Clear calculations showing the gross and net rental yields, confirming the property generates sufficient income to cover mortgage payments and running costs.
Dealing with Complex or Time-Sensitive Transactions
Sometimes, the financing required is not a long-term commercial mortgage but an interim solution, such as a bridging loan, often used for property refurbishment, quick purchases at auction, or managing a cash-flow gap before longer-term finance is secured.
If your commercial proposal involves financing the acquisition rapidly or undertaking significant refurbishment before applying for a permanent mortgage, you may consider bridging finance. The documentation requirements for bridging loans are often similar to standard commercial mortgages but are processed much faster, focusing heavily on the exit strategy (how you plan to repay the short-term loan).
Important Risk Warning
If you opt for short-term secured lending like a bridging loan, or any commercial mortgage, it is vital to understand the risks. Your property may be at risk if repayments are not made. Consequences of default can include legal action, repossession, increased interest rates, and additional charges and fees applied by the lender. Always ensure your projections account for potential delays in your exit strategy.
Structuring and Presenting Your Commercial Proposal
A poorly organised proposal can signal potential disorganisation within the business itself. Presentation matters significantly. We recommend ensuring the following structural elements are clearly presented:
- Table of Contents: Essential for large documents, allowing lenders and underwriters to quickly locate specific information.
- Standardised Formatting: Ensure all financial statements use consistent reporting periods and currencies (GBP).
- Clear Narrative: Use the proposal to address potential weaknesses proactively. If your company had a bad trading year, explain the cause (e.g., pandemic impact, large one-off investment) and what mitigating steps were taken.
- Professional Assistance: Utilise the expertise of a commercial finance broker or an accountant experienced in securing commercial funding. They can help structure the proposal optimally for the lender’s criteria, ensuring you include everything required in your commercial property mortgage proposal.
People also asked
How long does the commercial mortgage proposal process typically take?
While an initial decision (Agreement in Principle) can often be made quickly once the proposal is submitted, the full underwriting process typically takes between six and twelve weeks, depending on the complexity of the security, the required valuation and survey reports, and the speed of legal conveyancing.
What is the typical Loan-to-Value (LTV) for a commercial property mortgage?
Commercial LTVs are generally lower than residential mortgages. While specific rates vary by lender and property type, LTVs usually range between 50% and 75% of the property’s value, meaning you typically need a minimum deposit of 25% to 50%.
Is a Personal Guarantee (PG) always required for a commercial mortgage?
For loans to Limited Companies or LLPs, lenders almost always require a Personal Guarantee (PG) from the directors or key shareholders. This allows the lender recourse to personal assets if the business cannot repay the debt, fundamentally reducing the lender’s overall risk.
What if my business has limited trading history?
Start-up businesses or those with less than three years of trading history often face greater difficulty and higher rates. Your proposal must compensate by having an exceptionally robust, detailed business plan, stronger personal finances from the directors, and a larger deposit (lower LTV).
Are commercial property mortgage interest rates fixed or variable?
Commercial mortgages can be offered on a fixed, variable (linked to the Bank of England Base Rate or LIBOR/SONIA), or tracker basis. The choice depends on the borrower’s risk appetite and the lender’s product offering, though variable rates are very common in commercial finance.
Does the use of the commercial property affect the mortgage proposal requirements?
Yes, the proposed use (e.g., retail, industrial warehouse, office, semi-commercial property) significantly influences risk assessment. Specialist properties (e.g., pubs, hotels, care homes) often require lenders with specific sector experience and may require a greater focus on the operational plan and sector-specific financial metrics within the proposal.
Final Considerations for Your Commercial Proposal
When compiling your commercial property mortgage proposal, remember that the lender is looking for consistency, credibility, and security. Every figure you provide should be supported by documented evidence, and every projection should be based on conservative, well-justified assumptions.
By investing time in creating a highly detailed and professionally structured application that clearly addresses all aspects of your financial strength, business viability, and asset quality, you significantly improve your chances of securing favourable commercial finance terms.
