Limited company buy to let mortgage articles of association SPV is a specialist mortgage product designed for landlords purchasing or remortgaging investment properties through a Special Purpose Vehicle (SPV) limited company. In 2025, this structure has become increasingly popular among UK property investors due to the tax efficiencies and flexibility it offers. Unlike personal buy-to-let lending, this route requires a company registered with Companies House, typically using SIC codes related to property letting. One essential requirement is having suitable Articles of Association aligned with property rental activity.
Landlords are drawn to this option for its potential tax advantages, particularly following changes to mortgage interest relief under Section 24. Lenders assess affordability based on rental income rather than personal earnings, making it attractive to portfolio landlords and higher-rate taxpayers. With BTL mortgage rates stabilising and lenders expanding their criteria, now is a favourable time to consider this investment property finance route.

How This Mortgage Works
A limited company buy to let mortgage articles of association SPV works by allowing landlords to purchase or refinance rental properties through a limited company set up solely for property investment. This SPV must be registered with Companies House and have appropriate SIC codes (e.g., 68209 or 68100). The Articles of Association must reflect the company’s purpose of letting property, which lenders will review as part of the application.
These mortgages come in various product types, including fixed-rate (typically 2-5 years), variable-rate, and tracker options. Fixed-rate products are popular for budgeting stability, especially in a rising interest rate environment.
This type of mortgage suits both new and experienced landlords, particularly those building a portfolio or seeking to mitigate tax liabilities. Many lenders now cater specifically to SPV limited companies, with some offering streamlined underwriting for portfolio landlords.
Unlike residential mortgages, affordability is assessed primarily on rental income rather than personal earnings. This makes it ideal for landlords with multiple properties or those with limited personal income. However, lenders still consider creditworthiness and may require personal guarantees from directors.
Eligibility and Criteria
To qualify for a limited company buy to let mortgage articles of association SPV, applicants must meet a range of criteria set by lenders. While personal income is less critical than in residential lending, some lenders still require a minimum income threshold, typically around £25,000 per annum, to ensure financial stability.
Rental income is the primary affordability metric. Lenders use a rental coverage ratio, usually between 125% and 145%, calculated at a stress-tested interest rate (e.g., 5.5% or higher). For example, a property generating £1,000 monthly rent would need to cover a notional mortgage payment of £690 to £800, depending on the lender’s stress rate and coverage requirement.
Property type also plays a role. Most lenders prefer standard construction buy-to-lets, such as single-family homes or flats. Some may restrict lending on HMOs, new builds, or flats above commercial premises. Others specialise in these niches, particularly for experienced landlords.
Credit score requirements vary, but a clean credit history is essential. Minor issues may be accepted, especially if the applicant has strong rental income and experience.
Age limits typically range from 21 to 85, with some lenders imposing maximum age limits at the end of the mortgage term. Employment status is less relevant, but self-employed applicants must show stable income or rental history.
Portfolio landlords—those with four or more mortgaged properties—face additional scrutiny. Lenders assess the entire portfolio’s performance, including rental coverage, leverage, and property types. A business plan and property schedule are often required (Read our guide to portfolio landlord mortgages).
Limited company applications differ from personal name ones in that the company becomes the borrower. However, directors and shareholders usually provide personal guarantees. The company must have suitable Articles of Association, and some lenders may require bespoke amendments if the standard template is insufficient.
Right-to-rent compliance and local licensing (e.g., for HMOs) must also be in place, as lenders will not fund properties that breach legal requirements.
Costs and Affordability
When applying for a limited company buy to let mortgage articles of association SPV, landlords must budget for several costs. Arrangement fees typically range from 1% to 2% of the loan amount. Valuation fees vary depending on property value, usually starting from £300. Legal fees for limited company mortgages are often higher due to the complexity of company structures and may exceed £1,000. Broker fees may apply if using a specialist adviser.
Interest rates for limited company BTL mortgages are generally 0.25% to 0.75% higher than personal buy-to-let rates. Fixed rates offer predictability, while variable and tracker options may be cheaper initially but carry more risk.
Rental income must meet the lender’s stress test, often calculated at 125% to 145% of a notional interest rate. Some lenders offer top-slicing, allowing personal income to supplement rental shortfalls.
Taxation is a major driver for using an SPV. Unlike individual landlords, limited companies can deduct mortgage interest as a business expense, avoiding the Section 24 restrictions. However, corporation tax, dividend tax, and accounting costs must be factored in.
Insurance is mandatory, including buildings insurance and often landlord insurance covering liability and loss of rent.
The Application Process
Securing a limited company buy to let mortgage articles of association SPV involves several key steps:
1. Research and Preparation – Determine your investment goals, company structure, and property type. Ensure your SPV is registered with the appropriate SIC codes and has suitable Articles of Association.
2. Mortgage Agreement in Principle – Work with a broker or lender to obtain an AIP based on your company and property details.
3. Submit Full Application – Provide documentation including SPV registration, Articles of Association, director ID, property details, rental projections, and existing portfolio information if applicable.
4. Valuation and Underwriting – The lender will instruct a valuation and assess the property’s rental potential. Underwriters will review your company structure, credit profile, and affordability.
5. Offer and Legal Work – Once approved, the lender issues a formal offer. Solicitors complete legal checks, including company searches and director guarantees.
6. Completion – Funds are released and the mortgage is completed. You can then let the property under the SPV structure.
Applications typically take 4 to 8 weeks, depending on complexity. Working with a mortgage broker can streamline the process and improve approval chances.
Common reasons for rejection include unsuitable Articles of Association, poor credit history, insufficient rental income, or non-compliant property types.
Benefits, Risks and Alternatives
Using a limited company buy to let mortgage articles of association SPV offers several benefits. Chief among them is the ability to offset mortgage interest against rental income, which is no longer available to individual landlords due to Section 24. This structure also facilitates long-term portfolio growth and inheritance planning.
However, risks include higher mortgage rates, increased legal and accounting costs, and potential void periods affecting cash flow. Regulatory changes, such as licensing laws or EPC requirements, could impact profitability. Interest rate rises may also affect affordability on variable products.
Alternative finance options include bridging loans (for short-term purchases or refurbishments), commercial mortgages (for mixed-use or semi-commercial properties), and development finance (for conversions or new builds).
Landlords should also compare remortgaging with product transfers. While remortgaging can unlock better rates or release equity, product transfers may offer faster processing and lower fees.
