What’s the average processing time for a commercial mortgage application?
13th February 2026
By Simon Carr
Navigating the commercial mortgage application process requires understanding the timescales involved, which can vary significantly more than residential mortgages. While a straightforward application might complete in 4 to 8 weeks, more complex cases—involving specialist properties, multiple borrowers, or complicated legal structures—can take 12 weeks or longer. Speed depends heavily on preparation, the efficiency of the legal teams, and the complexity of the property being financed.
What’s the average processing time for a commercial mortgage application?
The term “average” can be misleading when discussing commercial finance. Unlike standard residential loans, commercial mortgage applications deal with diverse property types (offices, shops, industrial units) and complex business structures. Therefore, processing times are highly variable, making a single average figure difficult to rely upon.
Generally, you should budget for a minimum of 6 to 8 weeks from initial enquiry to funds being drawn down. However, it is not uncommon for complex or highly structured deals to take 12 weeks, and sometimes significantly longer if legal issues or planning restrictions arise.
The Key Stages of a Commercial Mortgage Application
Understanding the application journey helps set realistic expectations for the timeline. The total processing duration is essentially the sum of time spent in the following four core stages:
Stage 1: Initial Enquiry and Agreement in Principle (AIP)
This is the fastest stage. Once you submit initial details about the property, your business, and the required loan amount, the lender assesses basic affordability and risk. If acceptable, they issue an Agreement in Principle (AIP) or Head of Terms. This usually takes between 24 hours and one week.
- Timeframe: 1–7 days.
Stage 2: Formal Application and Underwriting
Once the AIP is issued, you proceed to the formal application, providing comprehensive financial documentation. The underwriting team meticulously reviews everything, including business accounts, projections, personal financial statements, and business plans. The quality and completeness of these documents are crucial to avoiding delays.
Lenders will also conduct due diligence on the principals involved. This often involves a credit search to assess financial history and risk profile.

- Timeframe: 1–3 weeks (highly dependent on document quality).
Stage 3: Valuation and Due Diligence
The lender requires an independent valuation of the commercial property to confirm its market value and suitability as security for the loan. For specialist properties (e.g., hotels, petrol stations), finding a suitable surveyor and completing the comprehensive report can take longer than for standard office space.
Legal due diligence by the lender’s solicitor begins simultaneously. They check legal titles, leases, environmental concerns, and local authority searches.
- Timeframe: 2–4 weeks.
Stage 4: Legal Completion and Funds Release
This final stage involves the solicitor confirming all conditions have been met, finalising the loan agreement, and registering the charge against the property. Once all legal requirements are satisfied and the solicitor receives all funds from the lender, they can be drawn down.
- Timeframe: 1–3 weeks.
Total typical processing time, combining these stages, usually sits between 6 and 12 weeks.
What Factors Influence Processing Speed?
The total duration of your commercial mortgage application is rarely dictated solely by the lender. Several external and internal factors can significantly lengthen or shorten the process.
1. Complexity of the Property
A simple, standard commercial property with a clear title and existing tenancy history will generally proceed quicker than a complex, mixed-use development or a property requiring significant refurbishment. Specialist properties often require more in-depth valuations and specific environmental searches.
2. Quality of Documentation and Borrower Profile
Lenders need complete, accurate, and recent financial information. If the applicant’s accounts are complex, incomplete, or require back-and-forth clarification, the underwriting stage will stall. Clear documentation regarding company structure, turnover, profit and loss, and tax returns is vital.

3. Lender Type and Capacity
Large high-street banks typically have standard processes but can sometimes experience backlogs. Specialist commercial lenders and independent finance providers may offer more flexibility and often quicker turnaround times, especially for niche or non-standard deals, although this may come with different terms or interest rates.
4. Legal Search Delays
The longest delays often occur during the legal phase. Local authority searches, required to check planning permissions and restrictions, are frequently subject to local council processing times, which can vary wildly across the UK.
5. Broker Involvement
Using an experienced commercial finance broker can often accelerate the process. Brokers understand the specific requirements of different lenders and can pre-package your application to ensure all necessary documents are provided upfront, minimising underwriter queries.
Tips on How to Speed Up Your Application
While you cannot control lender capacity or local authority search times, you can proactively manage your own preparation to ensure maximum efficiency:
- Prepare Documentation Early: Before submitting an AIP, have two to three years of audited accounts, VAT returns, comprehensive business plans, and proof of identification ready.
- Ensure Legal Clarity: If you know the property has complex legal elements (e.g., easements, restrictive covenants), flag these with your solicitor immediately. Instructing an experienced commercial property solicitor right away is crucial.
- Be Responsive: Any time the lender or solicitor requests additional information, provide it immediately. Delays of even a day or two can add weeks to the final completion time.
- Manage Existing Debts: Lenders scrutinise existing financial commitments. Ensuring that any outstanding loans or agreements are clearly documented, and preferably reduced, can streamline the assessment.
It is important to remember that rushing the due diligence process can be risky. A thorough legal and valuation process protects your investment and ensures you are aware of any potential issues with the property before committing to the loan.
People also asked
How much deposit do I need for a commercial mortgage?
Typically, commercial lenders require a minimum deposit of 25% to 40% of the property value, depending on the property type, the strength of the business plan, and the lender’s risk assessment. High Loan-to-Value (LTV) products, requiring smaller deposits, usually involve higher interest rates.
Are commercial mortgage applications harder than residential ones?
Yes, generally commercial applications are significantly more complex. They involve assessing not just personal affordability but also the financial health and future viability of the underlying business, leading to more extensive due diligence and documentation requirements.
How long does the valuation survey take?
The time taken for the surveyor to visit the site and prepare the formal report usually takes between 1 and 3 weeks, although accessing specialist properties or managing busy surveyor schedules can extend this. The lender will only proceed to formal offer once this report is received and approved.
Can I use a bridging loan to secure a commercial property quickly?
Bridging loans are specialist short-term finance options often used to secure a property quickly (sometimes in just 2-3 weeks) before refinancing onto a standard commercial mortgage. However, bridging loans are secured against property, and your property may be at risk if repayments are not made. Consequences of default could include legal action, repossession, increased interest rates, and additional charges.
What is the minimum lending period for a commercial mortgage?
Commercial mortgage terms are highly flexible, usually ranging from 5 years up to 25 years. Short-term loans (under 5 years) are less common for mortgages but may be appropriate if the borrower plans to sell the property or refinance quickly.
In summary, while there is no single definitive answer to what’s the average commercial mortgage processing time, applicants who approach the process with meticulous documentation and excellent communication should expect completion within 8 to 12 weeks. Preparing thoroughly and engaging a competent solicitor early on remains the single best way to ensure a smooth and efficient timeline.
