What are the typical legal fees involved in a commercial mortgage?
13th February 2026
By Simon Carr
Navigating the acquisition or refinancing of commercial property in the UK involves several unavoidable costs, and among the most significant are the legal fees. Unlike residential mortgages, commercial transactions are complex, often involving detailed due diligence on tenants, planning regulations, environmental risks, and corporate structures. Understanding what are the typical legal fees involved in a commercial mortgage is essential for accurate budgeting and ensuring a smooth completion process.
What Are the Typical Legal Fees Involved in a Commercial Mortgage?
Commercial mortgages provide the crucial funding necessary for businesses to acquire property, expand premises, or invest in new ventures. However, before the funds are released, the legal integrity of the deal must be meticulously verified. This process requires specialist solicitors and results in significant costs that the borrower is almost always required to cover.
The legal costs associated with a commercial mortgage generally fall into two main categories:
- Lender’s Legal Fees: These are the professional fees and disbursements incurred by the lending institution’s solicitor, which the borrower is contracted to pay.
- Borrower’s Legal Fees: These are the professional fees incurred by the borrower’s own solicitor for providing independent advice, reviewing the loan documentation, and ensuring the property title is correctly transferred or charged.
Due to the bespoke nature of commercial transactions, these fees are rarely fixed and can fluctuate wildly depending on the loan amount, the type of property, and the complexity of the legal structure of the borrowing entity.
The Essential Role of the Lender’s Solicitor
The primary concern of the lender is security. They need absolute assurance that if the borrower defaults, they can legally enforce their charge over the property and recover the debt. The lender’s solicitor undertakes the rigorous due diligence required to guarantee this security, and the borrower pays for this work.
Professional Fees: Fixed vs. Hourly Rates
Lender solicitor fees are calculated either as a fixed fee or, more commonly for complex commercial deals, based on an hourly rate. The cost is often proportionate to the loan size, reflecting the increased risk and necessary checks required for high-value funding.
- Fixed Fees (Simpler Loans): For straightforward commercial mortgages, smaller loans, or refinancing a familiar property type, some lenders may offer a fixed fee structure, perhaps ranging from £2,500 to £5,000 plus VAT and disbursements. This provides cost certainty early in the process.
- Hourly Rates (Complex Loans): For larger transactions, development finance, or properties with existing complex lease structures (e.g., multi-tenanted offices), solicitors charge based on time spent. These rates can vary significantly based on the firm’s seniority and location, often starting from £250 per hour up to £500 or more for partner-level work.
Key Legal Tasks Covered by the Lender’s Solicitor
The bulk of the professional fees covers essential tasks that secure the loan:
Reviewing the Borrower’s Structure: If the borrower is a limited company, partnership, or trust, the solicitor verifies its legal capacity to borrow and ensures all necessary resolutions and director guarantees are properly executed.
Security Documentation Drafting: Creating and finalising the security documentation, including the legal charge over the property, the debenture (if relevant for corporate borrowers), and personal guarantee agreements.
Title Investigation: Thoroughly checking the property title held at HM Land Registry. This involves confirming the seller/borrower legally owns the property, identifying any existing easements, covenants, rights of way, or prior charges that could affect the lender’s primary security position.
Review of Leases and Tenancies: If the property generates rental income (e.g., an office block or retail unit), the solicitor reviews all existing leases to ensure they do not undermine the lender’s ability to take possession or receive income if necessary. This can be one of the most time-consuming and costly parts of the legal process.
Conditions Precedent (CPs): Ensuring all requirements set out in the initial loan offer letter—known as Conditions Precedent—are satisfied before drawdown.
Disbursements: The Third-Party Costs
Disbursements are specific, chargeable expenses paid to third parties by the solicitor on behalf of the client. These costs are mandatory and are passed directly onto the borrower. They can accumulate quickly, adding several thousand pounds to the overall legal bill.
Mandatory Searches and Checks
Commercial transactions require more extensive searches than residential ones, particularly concerning environmental and planning risks:
- Local Authority Searches (LAS): Required to check for planning history, road schemes, contaminated land notices, building regulations, and enforcement actions.
- Environmental Searches: Crucial for commercial sites, these checks assess the risk of land contamination (e.g., if the property was previously a factory or petrol station). If high risk is flagged, more expensive Phase I and Phase II site surveys may be required, dramatically increasing costs.
- Water and Drainage Searches: Confirming legal connections to public sewers and water supply and checking for any public drains running beneath the property that could limit future development.
- Land Registry Fees: Official fees paid to HM Land Registry for registering the legal charge (the mortgage) against the property title. The cost is scale-based, depending on the loan amount.
- Company Searches: Checks conducted against the borrower company at Companies House to confirm solvency, current directors, and any existing charges or insolvencies.
When lenders assess a commercial mortgage application, they look closely at the borrower’s financial health, which includes reviewing credit history. Get your free credit search here. It’s free for 30 days and costs £14.99 per month thereafter if you don’t cancel it. You can cancel at anytime. (Ad)
- Chancel Repair Liability Search: Although less common now, this check ensures the property is not liable for the repair costs of the local parish church.
The total cost of these disbursements can vary from £500 up to several thousand pounds, depending on the property’s location and previous use.
The Borrower’s Own Legal Representation
While the lender’s solicitor protects the lender, the borrower also requires independent legal advice. This is crucial for reviewing the complex loan documentation and ensuring the borrower understands the obligations and risks being undertaken.
Borrower solicitor fees will typically involve:
- Reviewing and Negotiating Loan Terms: Analysing the mortgage deed, debenture, and personal guarantees to ensure they align with the commercial deal agreed upon.
- Advising on Risk: Explaining the implications of default, enforcement rights, and the nature of the security being provided.
- Conveyancing (If Purchasing): Handling the actual acquisition of the property—drafting the contract for sale, managing stamp duty land tax (SDLT), and ensuring clean transfer of title.
The cost for the borrower’s solicitor often mirrors that of the lender’s solicitor, depending on the complexity, but may be slightly lower if the lender’s solicitor has undertaken the bulk of the initial property due diligence. You should budget for fees starting at around £1,500 and rising significantly for high-value or complex transactions.
It is crucial that borrowers receive independent advice. For commercial mortgages, particularly those involving high leverage or significant personal guarantees, understanding the potential impact of non-repayment is vital. Your property may be at risk if repayments are not made. Consequences of default include legal action, increased interest rates, additional charges, and ultimately, repossession.
Factors Driving Up Commercial Legal Costs
Several variables can significantly increase the legal time required and, consequently, the fees involved in a commercial mortgage:
1. Complexity of the Property
- Multi-Use Properties: Properties combining residential, retail, and industrial usage require layered planning and lease review.
- Development Sites: These require extensive checks on planning permission, infrastructure agreements (Section 106), and rights of way, leading to high legal bills.
- Specialised Assets: Pubs, care homes, or farms involve specific licensing, regulatory checks, and sector-specific documentation that requires niche legal expertise.
2. The Corporate Structure of the Borrower
If the borrower is an offshore entity, a complex trust, or a new Special Purpose Vehicle (SPV), the verification process (Know Your Customer/Anti-Money Laundering) and the drafting of security documents become far more involved, increasing legal time.
3. Leasehold vs. Freehold
While freehold ownership tends to be simpler, commercial leaseholds require solicitors to review the headlease terms, often requiring a Deed of Covenant with the freeholder, adding further complexity and cost.
4. Dealing with Legal Issues
If the solicitors uncover existing boundary disputes, breaches of planning conditions, or unregistered easements during their searches, resolving these issues can halt the transaction and lead to significant extra legal fees charged hourly.

How to Manage and Budget for Commercial Legal Fees
While legal costs are unavoidable, you can take steps to manage them effectively:
1. Request a Fee Estimate Upfront: Demand a detailed breakdown from both the lender’s solicitor (via the lender or broker) and your own, clearly separating professional fees, VAT, and estimated disbursements. Understand whether the professional fee is fixed or hourly.
2. Prepare Documentation: Ensure all corporate documents (company registration, articles of association, director IDs, board minutes) are up-to-date and readily available. Delays caused by the borrower searching for documentation often result in hourly charges from the lender’s solicitor.
3. Use Experienced Commercial Solicitors: Choosing a solicitor familiar with commercial mortgage procedures and the specific lender can expedite the process, reducing billable hours caused by learning curves or technical mistakes.
4. Budget for Contingency: Given the variable nature of commercial property checks, always budget a contingency fund—perhaps 10% to 20% above the initial estimated legal fee—to cover unexpected search findings or title complications.
People also asked
Are commercial legal fees included in the mortgage loan?
Typically, no. While the lender will often require proof that the borrower has sufficient funds to cover the completion costs (including legal fees and disbursements) before drawdown, these costs are almost always paid by the borrower directly to the respective solicitors upon completion, rather than being rolled into the principal loan amount.
How much VAT do I pay on commercial legal fees?
Legal professional fees and most search disbursement fees are subject to the standard rate of Value Added Tax (VAT) in the UK, currently 20%. However, certain official fees, such as Land Registry fees and Stamp Duty Land Tax (SDLT), are not subject to VAT.
What is the difference between legal fees and lender arrangement fees?
Legal fees cover the professional services and administrative costs incurred by the solicitors to establish the legal security of the loan. In contrast, the lender arrangement fee (or facility fee) is the charge levied by the lender itself for setting up the mortgage facility. Both are separate costs that form part of the total cost of borrowing.
Do I have to use the lender’s solicitor?
Yes, you must use the solicitor nominated or approved by the lender, as that solicitor acts on the lender’s behalf to protect their interests. However, you are legally required and highly advised to hire your own independent solicitor to review the documents on your behalf.
Can legal fees be negotiated in a commercial mortgage?
The lender’s solicitor’s professional fees are typically set by the lending institution or the firm itself and are difficult to negotiate. However, you can negotiate the fees charged by your own independent solicitor. If the lender’s fees are based on hourly rates, efficiency and thorough preparation on the borrower’s part can indirectly reduce the total time billed.
Conclusion
The legal fees involved in a commercial mortgage represent a necessary and significant investment into the security and compliance of the transaction. By understanding that you are paying for two distinct legal teams—one dedicated to protecting the lender’s interest and one dedicated to advising your business—and by budgeting carefully for variable professional fees and extensive disbursements, commercial borrowers can navigate this complex part of the property finance journey with greater clarity and fewer unexpected costs.
