Limited company buy to let mortgage articles of association 2 year fixed products are increasingly popular among UK landlords looking to optimise their property investment strategy. These mortgages are designed for landlords purchasing or remortgaging buy-to-let properties through a limited company structure, with a fixed interest rate for two years. The “articles of association” refer to the company’s governing document, which must permit property letting activities.

This type of landlord mortgage offers predictable repayments, making it attractive in a fluctuating interest rate environment. With buy-to-let lending criteria becoming more specialised, fixed-rate investment property finance through a limited company provides both stability and strategic tax advantages. Whether you’re a first-time investor or a portfolio landlord, understanding how this mortgage works is essential to maximising returns and ensuring compliance with current regulations.

Limited company buy-to-let mortgages with a 2-year fixed rate offer short-term rate security and are ideal for landlords planning future remortgages. Lenders assess affordability based on rental income, not personal salary, and require the company’s articles of association to explicitly allow property letting. These products are widely available from specialist lenders and some mainstream banks.
How This Mortgage Works
A limited company buy to let mortgage articles of association 2 year fixed is a mortgage product tailored for landlords operating through a limited company structure, such as a Special Purpose Vehicle (SPV). The 2-year fixed rate element means the interest rate remains unchanged for the first 24 months, offering certainty over monthly repayments.
This mortgage type is commonly used by landlords aiming to benefit from tax efficiencies, particularly since the introduction of Section 24, which restricts mortgage interest relief for individual landlords. By using a limited company, mortgage interest can still be treated as a business expense, potentially reducing corporation tax liabilities.
The articles of association must include clauses allowing property letting. Lenders will review this document during underwriting to ensure the company’s purpose aligns with buy-to-let activity. Most lenders prefer SPVs registered under SIC code 68209 (letting and operating of own or leased real estate).
This mortgage suits both new landlords and experienced portfolio investors. It differs from residential mortgages in that affordability is based on projected rental income, not personal income. In 2025, lender appetite remains strong, with competitive BTL mortgage rates and flexible criteria for limited companies.
Eligibility and Criteria
To qualify for a limited company buy to let mortgage articles of association 2 year fixed, borrowers must meet specific eligibility requirements set by lenders. These include both company-level and personal criteria.
Income requirements are typically less stringent than residential mortgages. Lenders focus on rental income rather than personal earnings, although some may require a minimum personal income of £25,000 to £30,000, especially for non-portfolio landlords.
Rental coverage is a key affordability metric. Most lenders require the projected rental income to cover 125% to 145% of the mortgage payments, stress-tested at a notional interest rate (often 5.5% to 6.5%). This ensures the mortgage remains affordable even if interest rates rise.
Property type restrictions apply. Standard buy-to-let properties such as single-unit houses and flats are widely accepted. However, HMOs (houses in multiple occupation), new builds, and flats above commercial premises may be subject to additional scrutiny or higher deposit requirements.
Credit score expectations vary, but a good credit history is essential. Most lenders require no recent adverse credit, CCJs, or bankruptcies. A clean credit file improves access to competitive rates.
Age limits typically range from 21 to 85 at the end of the mortgage term. Employment status is less critical, especially for SPV applications, but self-employed directors must provide company accounts and tax returns.
Portfolio landlords (those with four or more mortgaged buy-to-let properties) face additional criteria. Lenders assess the entire portfolio’s performance, including rental income, LTV ratios, and property types. Stress testing may be applied across the portfolio.
Applications through a limited company must include valid articles of association, a certificate of incorporation, and SIC codes relevant to property letting. Right-to-rent compliance and local authority licensing (especially for HMOs) are also required.
Costs and Affordability
Understanding the costs involved in a limited company buy to let mortgage articles of association 2 year fixed is crucial for budgeting and long-term planning.
Arrangement fees typically range from 1% to 2% of the loan amount. Some lenders offer fee-free options with slightly higher interest rates. Valuation fees depend on the property value, while legal fees are usually higher than residential purchases due to the company structure.
Interest rates for 2-year fixed products in 2025 range from 4.5% to 6.5%, depending on the lender, LTV, and applicant profile. Fixed rates offer repayment stability, while variable or tracker rates may offer lower initial costs but carry risk if rates rise.
Rental income is assessed using projected monthly rent, often verified by a letting agent or surveyor. This income must meet the lender’s rental coverage ratio, ensuring the mortgage is affordable even under stress testing.
Tax implications are a major consideration. Limited companies can deduct mortgage interest as a business expense, unlike individual landlords affected by Section 24. However, corporation tax and dividend tax may apply, so professional tax advice is essential.
Landlord insurance and buildings insurance are mandatory. Some lenders also require rent guarantee insurance. Stress testing is applied at higher notional rates to ensure affordability in case of future rate increases.
The Application Process
Applying for a limited company buy to let mortgage articles of association 2 year fixed involves several stages. Working with a specialist mortgage broker can streamline the process and improve approval chances.
Step 1: Research and pre-qualification. Understand your borrowing capacity, rental income expectations, and preferred lenders.
Step 2: Prepare documentation. This includes proof of ID, proof of address, company documents (certificate of incorporation, articles of association, SIC code), business bank statements, and property details.
Step 3: Submit application. Your broker or lender will assess the application, including credit checks and affordability calculations.
Step 4: Property valuation. A surveyor will assess the property’s value and rental potential. This is crucial for determining the loan amount.
Step 5: Legal process. Solicitors handle due diligence, company structure checks, and mortgage deed signing. This stage can take several weeks.
Step 6: Completion. Once all checks are complete and the mortgage offer is issued, funds are released and the purchase or remortgage completes.
Applications usually take 4 to 8 weeks. Common reasons for rejection include unsuitable articles of association, insufficient rental income, or poor credit history. A broker can help avoid these pitfalls and match you with the right lender.
Benefits, Risks and Alternatives
Limited company buy to let mortgage articles of association 2 year fixed products offer several benefits for property investors. These include tax efficiency, limited personal liability, and the ability to separate personal and business finances. The fixed rate provides short-term certainty, ideal for planning future remortgages or portfolio growth.
However, there are risks. Void periods, unexpected maintenance costs, and interest rate rises after the fixed term can affect profitability. Regulatory changes, such as EPC requirements or licensing rules, may also impact returns.
Alternative finance options include bridging loans for short-term purchases, commercial mortgages for mixed-use properties, and development finance for refurbishment or new builds. These may suit more complex investment strategies.
When the fixed term ends, landlords can choose to remortgage to a new product or opt for a product transfer with the same lender. Each option has pros and cons depending on fees, rates, and portfolio strategy.
Frequently Asked Questions
What deposit do I need for a limited company buy to let mortgage articles of association 2 year fixed?
Most lenders require a minimum deposit of 25% for limited company buy-to-let mortgages. However, some may ask for 30% or more depending on the property type, borrower profile, and rental income. Higher deposits can unlock better interest rates and improve affordability calculations. Specialist lenders may offer more flexibility for experienced landlords or strong company financials.
Can I get a limited company buy to let mortgage articles of association 2 year fixed through a limited company?
Yes, these mortgages are specifically designed for limited companies, particularly SPVs set up for property letting. The company must have appropriate SIC codes (e.g. 68209) and articles of association that permit buy-to-let activity. Lenders will assess both the company and the directors/shareholders during the application process. Many landlords choose this route for tax efficiency and portfolio management.
What rental coverage do lenders require?
Lenders typically require rental income to cover 125% to 145% of the mortgage payments, stress-tested at a notional rate (often 5.5% to 6.5%). For limited companies, the stress rate may be slightly lower than for personal applications. This ensures the mortgage remains affordable even if interest rates rise.

Section 24 restricts individual landlords from deducting mortgage interest from rental income for tax purposes. This can significantly increase tax bills. Limited companies are not affected by Section 24, as mortgage interest remains a deductible business expense. This is a key reason why many landlords now purchase or remortgage through a limited company structure.
