More UK landlords are moving their buy-to-let properties into limited companies, largely driven by Section 24 mortgage interest restrictions and tax efficiency. However, securing a buy-to-let limited company mortgage involves different criteria, rates, and processes compared to personal BTL lending.

This guide covers what you need to know about company mortgages, from eligibility requirements to the practical steps involved in securing finance for your property company.

How Buy-to-Let Limited Company Mortgages Work

A buy-to-let limited company mortgage is secured against a property owned by your limited company, not personally. The lender assesses both the company's finances and your personal situation as a director and guarantor.

Unlike personal BTL mortgages, company mortgages typically require personal guarantees from all directors with significant shareholdings (usually 20% or more). This means you remain personally liable if the company defaults, despite the corporate structure.

Most lenders treat company mortgages as commercial rather than residential lending, which affects both the application process and the regulatory protections available.

Interest Rates and Costs

Company mortgage rates are typically 0.25% to 0.75% higher than equivalent personal BTL rates. For example, where a personal BTL might be available at 4.5%, the company equivalent could be 5.0% to 5.25%.

The rate premium reflects the additional risk lenders perceive with corporate structures, plus the commercial lending classification. However, this cost difference often pales beside the tax savings available through incorporation, particularly for higher-rate taxpayers affected by Section 24.

Arrangement fees for company mortgages are often higher too, typically ranging from £1,000 to £3,000 compared to £500 to £1,500 for personal BTL products.

Eligibility Requirements

Lenders assess several factors when considering a buy-to-let limited company mortgage application:

  • Company structure: Most lenders prefer simple SPV (Special Purpose Vehicle) companies with straightforward shareholding structures
  • Director experience: Usually require at least 2-3 years of BTL experience, though some accept less with strong personal finances
  • Personal income: Directors typically need minimum personal income of £25,000 to £75,000 depending on the lender
  • Deposit requirements: Usually 25% minimum, though some lenders require 30-40% for company purchases
  • Rental coverage: Expected rental income usually needs to be 125-145% of mortgage payments at a stressed interest rate

The company itself needs to be UK incorporated with clear business purposes relating to property investment. Some lenders won't consider companies with multiple business activities.

Available Lenders and Products

The company BTL market is smaller than personal lending, with fewer lenders offering products. However, the market has expanded significantly since 2016.

Major players include specialist BTL lenders like Paragon Bank, Shawbrook, and Kent Reliance, plus some mainstream banks including Barclays and Santander. Building societies are less likely to offer company products.

Product types mirror personal BTL lending - you'll find fixed rates (2, 3, or 5 years), trackers, and discount variable rates. However, company products often have shorter initial periods and fewer long-term fixes available.

The Application Process

Applying for a buy-to-let limited company mortgage involves more documentation than personal applications:

Company documents required:

  • Certificate of incorporation
  • Memorandum and articles of association
  • Last two years' company accounts (if trading)
  • Company bank statements
  • Details of all directors and shareholders

Personal documents for directors:

  • Personal bank statements and income evidence
  • Details of existing BTL portfolio
  • Credit reports for all directors
  • Proof of BTL experience

Processing times are typically longer than personal mortgages - often 6-8 weeks compared to 4-6 weeks for personal BTL applications.

Tax Considerations

While mortgage rates might be higher, the tax benefits often justify company ownership for many landlords. Companies can still deduct full mortgage interest against rental profits, unlike individuals affected by Section 24 restrictions.

However, remember that extracting profits from the company creates additional tax charges through dividends or salary. The overall tax position depends on your total income, existing property portfolio, and future plans.

This is where specialist advice becomes crucial. Our calculators can provide initial guidance, but complex situations require detailed analysis of your specific circumstances.

Remortgaging Company Properties

Remortgaging works similarly to initial purchases, though established companies with trading history may find the process smoother. Lenders will want to see recent company accounts and evidence of successful property management.

Some landlords use remortgaging as an opportunity to transfer personally-held properties into company ownership, though this involves additional considerations around capital gains tax and stamp duty.

Common Pitfalls to Avoid

Several issues can derail company mortgage applications:

Complex company structures: Multiple subsidiaries, overseas ownership, or non-property business activities can put off lenders. Keep it simple where possible.

Inadequate deposits: Company mortgages typically need larger deposits than personal BTL. Budget for 25-30% minimum, potentially more for new companies.

Poor rental projections: Lenders stress-test rental coverage at higher interest rates. Ensure your rental income comfortably exceeds requirements, allowing for void periods and management costs.

Incomplete documentation: Company applications require extensive paperwork. Missing documents cause significant delays, so prepare thoroughly upfront.

Is a Company Mortgage Right for You?

Company mortgages make sense for many landlords, particularly:

  • Higher-rate taxpayers with substantial rental profits
  • Portfolio landlords planning significant expansion
  • Investors wanting to retain profits within the business
  • Those planning eventual sale to benefit from lower corporation tax rates on gains

However, they're not suitable for everyone. Small-scale landlords or those planning to extract most rental income immediately might find personal ownership more straightforward.

The decision involves balancing higher mortgage costs against tax savings, plus considering the administrative burden of running a limited company.
