What is a limited company buy-to-let mortgage?

A limited company buy-to-let mortgage is a mortgage that's aimed at limited companies rather than independent landlords. It's one way of getting a mortgage through your limited company, and not in your own name.

You need a Special Purpose Vehicle (SPV) to manage your residential rental portfolio to get a buy-to-let mortgage.

Your company has to be set up solely for property investments, including buying, letting and selling. Guarantors of the SPV will need to provide personal guarantees on the loan repayments.

Your business must be a limited (LTD) company registered with Companies House to apply for limited company mortgages. You must choose the correct SIC codes for your business activity, which you can do when setting up a Ltd company. You can include up to four SIC codes on your SPV.

There are several SIC codes related to property letting, such as:

  • 68209: Other letting and operating of own or leased real estate.
  • 68100: Buying and selling of own real estate
  • 68201: Renting and operating of Housing Association real estate. Housing associations provide social housing and support vulnerable members of society.
  • 68320: Management of real estate on a fee or contract basis.
  • 41100: Property development for businesses who work in the development of building projects.
  • 68310: Real estate agencies, so if you do property sourcing, deal sourcing and acting as an agent.

When you manage properties through a limited company, you can reduce the tax burden on your business as you will pay corporation tax rather than income tax on your rental income. However, you must continue paying income tax on your other personal income.

Limited companies have to pay stamp duty, but it is at the same rate as an individual for non-residential property. You are entitled to tax relief of 20% of mortgage interest payments yearly if they exceed £9,000.

The Financial Conduct Authority does not regulate buy-to-let mortgages, including traditional and limited company buy-to-let mortgages.

How can you get a limited company buy-to-let mortgage?

The criteria varies between limited company loan providers, depending on what loans they offer and rates.

However, there are standard criteria that most mortgage lenders follow, such as:

  • SIC codes: Limited companies or SPVs must be set up under a SIC code concerning their industry.
  • Minimum deposit: Most lenders expect you to put down a 20-25% minimum deposit, 25% of the property value. Depending on your financial circumstances, you could have to pay a higher or lower deposit.
  • Creditworthiness: The better credit history you and the other company directors have, the more likely you are to be accepted for a limited company loan.
  • Property-related criteria: Not all mortgage lenders support all types of buy-to-let property, for example, houses of multiple occupancy (HMOs).
  • Rental income: For most buy-to-let mortgage lenders, rental income must equal 125% of the mortgage repayments.

The pros and cons of limited company BTL mortgages

Before introducing you to the best limited company mortgages, we'll explore all the pros and cons to help you determine if this is the right decision.


✔️ Lower tax: You will pay less tax when you take out a limited company buy-to-let mortgage. You will only pay corporation tax instead of income tax. Corporation tax is set at a lower rate than income tax, so you could save money by being more tax efficient, especially if you fall into the additional or high-rate income tax bracket.

✔️ Grow property portfolio: When growing your investment portfolio with property investment, you can use retaining your profits within the company to fund future purchases without worrying about income tax, so you can continue to expand your portfolio.

 ✔️ Legacy planning: If you plan to pass your business on to your family in the future, and the property is held within the company, your family won’t have to pay stamp duty, inheritance tax, or capital gains tax liability.

✔️ Section 24 doesn't apply: Limited companies can offset 100% of the mortgage interest to reduce profits and the amount of tax paid.


❌️ Less choice: Not all buy-to-let lenders provide limited company buy-to-let mortgages, so your choice of properties may be limited.

❌️ Legal responsibilities: You must keep accurate business financial records and submit reports and documents to HMRC and Companies House. There are additional legal and financial responsibilities with limited company mortgages compared to normal ones.

❌️ No capital gains allowance: If you decide to resell the property or mortgage, you will be personally liable for Capital Gains Tax.

❌️ Double taxation: If you wish to take profits out via a salary or dividends, you will need to pay income tax, so you potentially risk paying both corporation and income tax. So, the best way to prevent this is to reinvest the profits into business.
