A limited company buy-to-let mortgage with a 5-year fixed rate offers predictable repayments and potential tax advantages. Lenders assess affordability based on projected rental income, not personal earnings, but strict criteria still apply. Articles of association must be tailored for property letting, and professional advice is essential.
How This Mortgage Works
A limited company buy to let mortgage articles of association 5 year fixed is a specialist product designed for landlords purchasing or refinancing rental properties through a limited company structure, typically a Special Purpose Vehicle (SPV). The 5-year fixed element refers to the interest rate being locked in for five years, offering stability against market fluctuations.
These mortgages differ from standard residential loans in that affordability is assessed primarily on rental income rather than personal income. Lenders require the limited company’s articles of association to explicitly permit property letting and management. Most lenders prefer SPVs registered with SIC code 68209 (Other letting and operating of own or leased real estate).
This mortgage type suits both first-time landlords and experienced portfolio investors seeking to benefit from tax efficiency and streamlined ownership. Portfolio landlords often use limited companies to manage multiple properties under one legal entity.
Current market trends show growing lender appetite for limited company buy-to-let lending, with competitive BTL mortgage rates and flexible criteria. Fixed-rate options are favoured due to rising interest rate volatility, offering landlords certainty over their investment costs for five years.
Eligibility and Criteria
To qualify for a limited company buy to let mortgage articles of association 5 year fixed, applicants must meet specific lender criteria. While affordability is based on rental income, personal financial health still plays a role.
Income Requirements:
Most lenders do not require a minimum personal income for SPV applications, but some prefer directors to earn at least £25,000 annually. Lenders may also assess the applicant’s ability to support the property during void periods.
Rental Coverage and Stress Testing:
Lenders typically require rental income to cover 125% to 145% of the mortgage payment, stress-tested at an assumed rate of 5.5% to 8.5%, depending on the lender and product. This ensures the property remains affordable even if interest rates rise.
Property Type Restrictions:
Standard buy-to-let properties such as single-family homes and flats are widely accepted. However, lenders may avoid non-standard construction, HMOs (unless specifically permitted), or properties above commercial premises.
Credit Score Expectations:
A good credit history is essential. While limited company applications are assessed on the company, directors’ personal credit profiles are also reviewed. Adverse credit, CCJs, or missed payments may limit lender options.
Age and Employment:
Most lenders set a minimum age of 21 and a maximum age of 85 at the end of the mortgage term. Employment status is considered, but self-employed applicants are accepted, especially if the company is newly formed.
Portfolio Landlord Criteria:
Landlords with four or more mortgaged properties must provide detailed portfolio summaries, including property values, rental income, and outstanding loans. Some lenders cap portfolio sizes or require a minimum level of experience.
Limited Company vs Personal Name:
Using a limited company can offer tax advantages, especially for higher-rate taxpayers affected by Section 24 restrictions. However, company set-up, running costs, and legal obligations must be considered. Personal name applications are simpler but may result in higher tax liabilities.
Compliance and Licensing:
Applicants must comply with Right-to-Rent checks and local authority licensing schemes. Articles of association must be tailored for property letting, and some lenders require specific clauses to be included.
Costs and Affordability
Understanding the full cost of a limited company buy to let mortgage articles of association 5 year fixed is crucial for long-term profitability.
Fees:
– Arrangement fees: Typically 1% to 2% of the loan
– Valuation fees: £300 to £1,000 depending on property value
– Legal fees: £800 to £1,500, often higher for limited companies
– Broker fees: Vary, but generally £495 to £1,500
Interest Rates:
Fixed rates for 5-year terms currently range from 4.75% to 6.25% depending on LTV, property type, and borrower profile. Variable and tracker rates may start lower but carry the risk of future increases.
Rental Income Calculations:
Lenders assess gross rental income against required coverage ratios. For example, a £200,000 loan at 5.5% stress rate would require rental income of around £1,145 per month at 145% coverage.
Taxation:
Limited companies are not affected by Section 24, meaning mortgage interest remains fully deductible. However, profits are subject to Corporation Tax (currently 25% in 2025), and extracting income via dividends may incur personal tax.
Insurance:
Landlords must hold buildings insurance and are advised to take out specialist landlord insurance covering loss of rent and liability.
Stress Testing:
Lenders stress test affordability at higher notional rates to ensure sustainability in the event of interest rate rises.

Benefits, Risks and Alternatives
Benefits of a limited company buy to let mortgage articles of association 5 year fixed include tax efficiency, fixed repayments for five years, and easier portfolio management. Limited companies can offset mortgage interest against rental income, unlike personal landlords affected by Section 24.
However, risks include:
– Higher interest rates and fees compared to personal mortgages
– Legal and accounting costs of running a company
– Regulatory changes impacting future tax treatment
– Void periods affecting cash flow
– Potential interest rate rises after the fixed term
Alternatives include:
– Bridging loans for short-term finance
– Commercial mortgages for mixed-use or large HMOs
– Development finance for refurbishment or new builds
– Product transfers at end of fixed term vs full remortgage
Remortgaging within a limited company can be more complex but may offer better rates or release equity.
Frequently Asked Questions
What deposit do I need for a buy-to-let mortgage?
Most lenders require a minimum deposit of 25% for a buy-to-let mortgage. However, for limited company applications, some lenders may ask for 30% depending on the property type and borrower profile. A higher deposit can unlock better interest rates and improve affordability metrics.
Can I get a limited company buy to let mortgage articles of association 5 year fixed through a limited company?
Yes, many lenders offer 5-year fixed buy-to-let mortgages to limited companies, particularly SPVs set up solely for property investment. The company’s articles of association must reflect property letting as a permitted activity, and lenders will assess both the company and directors during the application.
What rental coverage do lenders require?
Rental income must typically cover 125% to 145% of the mortgage payment, stress-tested at an interest rate of 5.5% to 8.5%. For example, a mortgage of £200,000 may require monthly rent of £1,145 at 145% coverage. Some lenders offer lower stress rates for 5-year fixed products.
How does Section 24 tax affect buy-to-let mortgages?
Section 24 restricts individual landlords from deducting mortgage interest from rental income for tax purposes. Limited companies are exempt, making them more tax-efficient for higher-rate taxpayers. This is a key reason many landlords now choose limited company structures for new purchases.
