Are Rates Higher for Limited Company Buy to Let Mortgages
In 2025, many UK landlords are asking: are rates higher for limited company buy to let mortgages? As property investment continues to evolve, more investors are choosing to hold buy-to-let properties within a limited company structure. This approach can offer tax advantages and greater flexibility, particularly for portfolio landlords. However, one of the most common concerns is whether mortgage interest rates are higher when borrowing through a limited company.
This article explores the current landscape of buy-to-let lending, focusing on limited company mortgages. We’ll cover how these mortgages work, who they suit, eligibility criteria, affordability assessments, and how they compare to personal name applications. Whether you’re a first-time landlord or a seasoned investor, understanding the nuances of limited company buy-to-let mortgages is essential for making informed decisions in today’s market.
Quick Facts
– Interest rates: 4.5% to 6.5% (as of early 2025)
– Minimum deposit: 25% (some lenders may require more)
– Rental coverage: 125% to 145% at a stressed interest rate

Limited company buy-to-let mortgages tend to have slightly higher interest rates than personal name mortgages. However, the tax efficiencies and portfolio flexibility often outweigh the cost difference for many landlords. Lenders assess applications based on rental income, affordability, and company structure, with specific criteria for portfolio landlords and SPVs (Special Purpose Vehicles).
Mortgage Overview
Limited company buy-to-let mortgages are designed for landlords purchasing or refinancing rental properties through a corporate structure, typically a Special Purpose Vehicle (SPV) limited company. These mortgages allow investors to separate personal and business finances, which can be beneficial for tax planning and liability management.
There are various product types available, including fixed-rate, variable, and tracker mortgages. Fixed-rate products are popular for budgeting purposes, especially in a fluctuating interest rate environment. Tracker and variable rates may offer lower initial costs but come with the risk of rate increases.
This type of mortgage is well-suited to experienced landlords, portfolio investors, and those looking to expand their property holdings under a limited company. It’s also increasingly used by first-time landlords seeking long-term tax efficiency.
Compared to standard residential mortgages, limited company buy-to-let mortgages are assessed differently. Lenders focus more on the property’s rental income than the applicant’s personal income. Additionally, the underwriting process considers the company’s structure, directors, and shareholders.
As of 2025, lender appetite for limited company buy-to-let lending remains strong, with more specialist lenders entering the market and offering competitive products tailored to investor needs.
Eligibility & Criteria
To qualify for a limited company buy-to-let mortgage, applicants must meet specific eligibility criteria. While personal income is less critical than with residential mortgages, lenders still conduct thorough assessments to ensure affordability and compliance with responsible lending standards.
Income Requirements
Most lenders do not require a minimum personal income for limited company applications, especially if the rental income sufficiently covers the mortgage. However, some may expect directors to earn at least £25,000 annually, particularly if personal guarantees are required.
Rental Coverage Calculations
Rental income is the primary affordability metric. Lenders typically require a rental coverage ratio of 125% to 145%, calculated at a stressed interest rate (usually around 5.5% to 6.5%). This ensures the property can generate enough income to cover the mortgage even if rates rise.
Property Type Restrictions
Not all properties are eligible. Lenders may restrict lending on:
– HMOs (Houses in Multiple Occupation)
– Multi-unit freehold blocks
– Flats above commercial premises
– Non-standard construction
Specialist lenders are more flexible with complex property types.
Credit Score Expectations
While credit scoring is less rigid for limited company applications, directors and shareholders must still demonstrate good credit history. Adverse credit, such as CCJs or defaults, can limit lender options.
Age and Employment Status
There are typically no upper age limits for limited company mortgages, as the loan is assessed on the business rather than the individual. However, directors must usually be over 21 and may need to show stable employment or self-employment history.
Portfolio Landlord Criteria
For landlords with four or more mortgaged properties, lenders apply additional scrutiny. This includes:
– Portfolio analysis
– Business plans
– Cash flow projections
– Experience in property management
Limited Company vs Personal Name
Limited company mortgages are assessed on the company’s structure, usually an SPV with a SIC code related to property letting (e.g., 68209). Personal guarantees from directors are often required. Compared to personal name applications, the process involves more documentation but can offer long-term tax benefits.
Compliance and Licensing
Applicants must comply with right-to-rent checks and local licensing laws. This is especially important for HMOs or properties in selective licensing areas. Lenders may request proof of compliance during the application process.
Costs & Affordability
Limited company buy-to-let mortgages come with several costs that landlords must factor into their affordability calculations.
Fees
– Arrangement fees: 1% to 2% of the loan amount
– Valuation fees: £300 to £800 depending on property value
– Legal fees: £1,000 to £2,000 (can be higher for complex cases)
– Broker fees: Vary by adviser, often £495 to £1,500
Interest Rate Comparison
Rates for limited company mortgages are typically 0.25% to 0.75% higher than personal name equivalents due to the perceived higher risk and complexity. Fixed rates offer stability, while variable rates may be cheaper initially but carry more risk.
Rental Income Calculations
Lenders assess rental income using a stress-tested interest rate, ensuring the property can cover the mortgage payments even in adverse conditions. This is a key part of the affordability test.
Tax Implications
One of the main reasons landlords choose limited company structures is to mitigate the impact of Section 24, which restricts mortgage interest relief for personally held properties. Limited companies can still deduct mortgage interest as a business expense, potentially reducing tax liabilities.
Insurance Requirements
Lenders require buildings insurance as a minimum. Landlord insurance, which includes liability and rent guarantee cover, is also recommended.
Stress Testing
Lenders apply stress testing to ensure affordability at higher interest rates. This protects both the borrower and the lender in a rising rate environment.
Application Process
Applying for a limited company buy-to-let mortgage involves several steps. Working with a mortgage broker can streamline the process and improve your chances of approval.

Valuation and Survey
The lender will instruct a valuation to determine the property’s market value and rental income. For HMOs or unusual properties, a more detailed survey may be required.
Timeline
The process typically takes 4 to 8 weeks, depending on the complexity of the case and responsiveness of solicitors. Delays can occur if the property requires licensing or if the company structure is non-standard.
Broker vs Direct Application
Using a broker can help navigate lender criteria, especially for portfolio landlords or complex cases. Brokers also have access to exclusive deals and can manage the application from start to finish.
