If you're a UK landlord, there's a good chance you've asked yourself whether your buy-to-let properties should be owned personally or through a limited company.
It's a question we discuss with landlords every day. Since the introduction of Section 24, the landscape has changed significantly, prompting thousands of property investors to rethink how they structure their portfolios. Today, limited company ownership has become increasingly mainstream, and for many landlords it offers compelling tax and borrowing advantages. However, it isn't right for everyone.
In this article, we'll explore the pros and cons of limited company buy-to-let ownership, discuss the latest mortgage market developments, and examine what recent housing market trends could mean for landlords and property investors.
Here’s your weekly MFB News update from 30th September 2026.
Why Are More Landlords Using Limited Companies?
The key driver behind the move towards limited company buy-to-let ownership has been the introduction of Section 24 mortgage interest relief restrictions.
Prior to these changes, landlords owning property in their personal names could deduct mortgage interest from their rental income before calculating tax. Section 24 removed this benefit, replacing it with a basic-rate tax credit for individuals. Limited companies, however, were unaffected and can continue to offset mortgage interest as a business expense.
As a result, the number of property-holding companies has increased dramatically over the past decade. More landlords are now establishing Special Purpose Vehicles (SPVs) and purchasing investment properties through company structures.
Just as importantly, lender appetite has grown significantly. What was once a niche area offered by specialist lenders is now supported by a much broader range of mortgage providers, creating greater choice for landlords seeking limited company mortgages.
The Advantages of Personal Ownership
Despite the popularity of limited companies, owning buy-to-let property personally can still be the right solution in certain circumstances.
The main benefit is simplicity. There are no company accounts to file, no annual returns to complete, and no ongoing administrative costs associated with running a business entity. Once tax has been paid, any remaining rental income belongs directly to the landlord without the need to consider how funds are extracted from a company.
Personal ownership can also remain attractive for:
- Basic-rate taxpayers
- Landlords with little or no mortgage borrowing
- Investors who rely on rental income to support their lifestyle
- Smaller portfolios with modest profits
For these landlords, the impact of Section 24 may be less significant than for highly leveraged investors.
The Challenges of Personal Buy-to-Let Ownership
For higher-rate taxpayers, the picture becomes more complicated.
Because mortgage interest relief is restricted, landlords can find themselves paying tax on income that does not reflect their actual profit after financing costs. In some cases, rental income can even push landlords into higher tax brackets, increasing their overall tax burden.
Mortgage affordability can also be affected.
Most buy-to-let lenders assess borrowing based on rental coverage calculations. Landlords purchasing in their own names as higher-rate taxpayers often face more restrictive calculations, which can reduce maximum borrowing levels compared with equivalent limited company applications.
In addition, ownership flexibility can be limited. Mortgage lenders typically restrict the number of borrowers that can be named on a mortgage, making more complex family ownership arrangements difficult to implement.
Why Limited Company Buy-to-Let Can Be Attractive
For many portfolio landlords, limited company ownership offers several important advantages.
The most obvious is tax efficiency. Mortgage interest remains fully deductible, and company profits are generally subject to corporation tax rather than personal income tax rates.
Limited companies can also make it easier to:
- Reinvest profits into future property purchases
- Build and scale a portfolio
- Plan for succession and estate management
- Introduce family members into ownership structures
- Create more sophisticated shareholding arrangements
Many landlords view these benefits as particularly valuable when building long-term property wealth.
Another advantage is access to more favourable rental affordability calculations, which can often support higher borrowing levels when compared with personal ownership.
What Are the Downsides of Limited Company Ownership?
Limited companies aren't without drawbacks.
Firstly, there are additional running costs. Annual accounts, company filings and ongoing administration create costs that do not exist with personal ownership.
Secondly, while company profits may be taxed efficiently, landlords must also consider how they intend to access those profits. Depending on whether income is taken as salary, dividends or loan repayments, a second layer of taxation may apply.
Landlords should also be cautious when considering transferring existing properties into a company structure. Although it can be done, the transfer is often treated as a genuine sale and purchase transaction, potentially triggering Capital Gains Tax and Stamp Duty Land Tax. Professional tax advice is essential before proceeding.
Finally, lenders will usually require personal guarantees, meaning directors remain personally responsible if the company cannot meet its mortgage obligations.
Mortgage Rates Remain Volatile
The mortgage market remains heavily influenced by expectations around future interest rates.
Recent movements in swap rates have pushed funding costs slightly higher, leading some lenders to reprice their mortgage products. While increases have not been widespread, the direction of travel serves as a reminder that mortgage pricing can change quickly.
For landlords planning a purchase, remortgage or portfolio expansion within the next six months, securing a rate early can provide valuable protection against future increases while retaining the potential to benefit if rates subsequently fall.
What Does the Latest Property Market Data Tell Us?
The UK property market continues to present a mixed picture.
More properties are coming to market, but buyer demand remains softer than expected. This means sellers are facing greater competition, making accurate pricing increasingly important.
Regional performance also varies significantly.
Scotland and parts of Northern England continue to demonstrate stronger price growth and buyer demand, while London and the South East face more challenging market conditions.
For landlords, the rental market remains equally nuanced. Although headline figures suggest some softening in average rents, much of this is driven by conditions in London. Across many other regions, rental demand remains strong and supply remains constrained.
Final Thoughts for Buy-to-Let Landlords
There is no universal answer to the limited company versus personal ownership debate.
For higher-rate taxpayers, heavily mortgaged landlords and investors focused on portfolio growth, a limited company structure may offer significant long-term advantages. For basic-rate taxpayers, debt-free landlords or those relying on rental income today, personal ownership may still be the most practical option.
The key is to assess both the taxation and mortgage implications together. Before making any decision, speak to an experienced mortgage broker and qualified tax adviser to understand how each option would affect your individual circumstances.
