Company Buy-to-Let Guide: how LTD/SPV mortgages work and whether they're right for you

What is limited company buy-to-let?

Limited company buy-to-let (often referred to as LTD buy-to-let or SPV buy-to-let) is a route where a rental property is owned through a UK limited company rather than by you personally.

In practice:

• The company is the legal owner of the property.
• Rental income is paid to the company.
• The company is responsible for dealing with relevant outgoings, including mortgage payments and allowable expenses.
• You typically receive money from the company through routes such as salary, dividends, or director's loan repayments (subject to your wider circumstances).

This separation between personal finances and the company's finances is one reason the structure appeals to some landlords.

In the buy-to-let market, this is commonly done through an SPV (Special Purpose Vehicle) structure—meaning the company is set up specifically for the purpose of buying, holding and letting residential property.

Can you get a buy-to-let mortgage through a limited company?

Yes. Limited company buy-to-let mortgages are available, but they are different from personal buy-to-let lending.

Because the products are assessed differently, lenders may focus more heavily on the company's structure and financial position than on an individual's personal circumstances alone. Limited company buy-to-let is typically more specialist than standard personal buy-to-let, which often means:

• fewer lenders offering the product
• more detailed underwriting
• criteria that can differ noticeably between lenders

What "unregulated" means in practice

Many buy-to-let mortgages are not regulated in the same way as residential mortgages. That can affect the level of consumer protection and the way product terms are presented. It also means lender criteria can vary widely from one lender to another.

Director's guarantee (and why it matters)

Some limited company buy-to-let mortgages require a director's guarantee. This is a contractual commitment from a director that can create personal exposure if the company cannot meet the mortgage obligations.

Even where a director's guarantee is not required, lenders will still want confidence that the company can service the debt and that the overall arrangement is sustainable.

Why landlords are moving to company structures in 2026

The UK buy-to-let market continues to evolve. For many landlords, higher borrowing costs, tighter regulation, and ongoing tax changes can reduce the appeal of owning rental property in a personal name.

As a result, more investors are reviewing whether a limited company structure—commonly set up as a Special Purpose Vehicle (SPV)—better supports their long-term strategy.

Mortgage interest tax relief is less beneficial for some individuals

A common reason landlords consider LTD buy-to-let is tax planning. Since changes to how landlords' buy-to-let mortgage interest is treated (implemented from 2020), some landlords have found their overall tax position may be different compared with before—particularly depending on their personal circumstances.

Where mortgage interest relief is restricted, landlords can find that their taxable profit (and therefore their tax bill) becomes harder to manage—particularly when interest rates are higher.

Note: Tax treatment depends on your individual circumstances. You should speak to a qualified tax adviser for advice specific to your situation.

Higher rates and affordability pressure

Even where rental income is strong, higher mortgage rates can reduce net yields. In practice, this can mean:

• less cash available for maintenance and improvements
• more frequent refinancing pressure
• greater sensitivity to void periods and rent changes

Stamp Duty, compliance and regulatory pressures

Stamp Duty costs have increased for additional properties, tax treatment of rental finance has tightened, and lenders have also become more focused on affordability and risk. Buy-to-let is also increasingly shaped by compliance requirements and tenant-facing reforms—landlords are expected to keep properties to standard and respond to changing rules around renting.

While these requirements apply regardless of ownership structure, the overall burden can make it harder for some landlords to stay competitive—and can make a company structure more attractive as an alternative.

A shift in market behaviour

As more landlords learn about company structures and see them used by other investors, adoption can accelerate. What starts as a niche option can become more common—particularly for landlords building portfolios, where the structure may be considered as part of a longer-term plan. Limited company lending can play a role by:

• Providing another route to finance when individual landlord mortgages feel less accessible.
• Supporting landlords who want to manage rental income and expenses through a business structure.
• Helping maintain investment activity by widening the pool of borrowers who can meet lender requirements.

However, it's not a universal solution. Suitability depends on the landlord's circumstances, the property type, expected rental performance, and the lender's approach to company applications.

Potential advantages of limited company buy-to-let

Limited company buy-to-let can offer benefits, but they are not automatic—outcomes depend on the lender, the property, and the company's setup.

1) Corporation tax may be lower than personal income tax for some landlords

For some investors, company ownership can sometimes be more tax-efficient—but this is not automatic and depends on profit levels and how you're taxed overall. Instead of income tax on personal rental profits, the company pays corporation tax on its profits (subject to the rules that apply to the company's circumstances).

2) Mortgage interest and expenses may be treated differently

The way mortgage interest is accounted for can differ between personal and company ownership. Where the mortgage is in the company's name, mortgage interest may be treated as a business expense in the context of company accounting. For some landlords, this may improve the net position of the investment, but results vary.

Beyond interest, lenders and accountants will both want clarity on what costs are being incurred and how they are recorded. Property-related expenses, service costs, and management arrangements can all affect the company's accounts.

3) A clearer structure for portfolio growth

For landlords building multiple properties, a limited company can provide a more consistent framework for:

• tracking income and expenses
• managing costs across the portfolio
• retaining profits within the company (where appropriate)
• funding future purchases (subject to available lending and affordability)

4) Portfolio expansion can be strategically easier

Some landlords prefer to build a portfolio through a company structure, particularly where future ownership changes or reorganisations are part of their plan.

5) Lender focus can shift toward company performance

For some borrowers, the company's rental track record and accounts can be the main story lenders want to understand—rather than relying solely on personal income.

6) Potentially smoother internal ownership changes

If the company is sold or ownership of the company changes, the property is typically already held within that structure. Shares in a company can be transferred more straightforwardly than transferring individual properties, though the overall tax and legal position will depend on the circumstances.

7) A corporate framework for governance and record-keeping

Limited company ownership typically comes with more formal administration than personal ownership. For some landlords, that structure is a benefit:

• clearer separation of investment activities
• more consistent reporting to support decision-making
• a framework that can align with professional advice (accountants, tax planning, and specialist mortgage sourcing)

8) Practical governance where more than one investor is involved

If multiple parties are involved, a company can make it easier to reflect ownership and decision-making through shareholdings and director arrangements.

9) Limited liability (with lender requirements in mind)

A limited company is a separate legal entity. In principle, this can help separate personal assets from the company's liabilities. However, in practice, lenders may still require additional protections (for example, personal guarantees in some cases). So limited liability should be viewed as a structural consideration—not an automatic shield.

10) Access to specialist buy-to-let lenders

Some lenders focus specifically on limited company buy-to-let lending. If your structure is aligned with property investment activity, it can help your application fit within a lender's typical approach.

The main drawbacks and trade-offs

Limited company buy-to-let isn't "better" in every case. Common downsides include:

1) Higher borrowing costs (in many cases)

In many cases, limited company buy-to-let mortgages can involve:

• higher interest rates than some personal buy-to-let options
• larger arrangement fees
• higher deposit requirements (requirements vary by lender and deal)

Arrangement fees, product pricing, and legal costs can be higher depending on the lender and the complexity of the transaction.

2) More admin and ongoing expenses

Running a limited company involves additional responsibilities, such as:

• company formation and setup steps
• annual accounts and corporation tax returns
• potential accountant fees

For smaller portfolios or lower profit levels, these costs may outweigh the benefits.

3) Tax on gains when you sell

When a property is sold, the company may be liable to corporation tax on any gains. This can change the long-term exit picture compared with selling personally.

4) Complexity around extracting money

Even if the company pays corporation tax, you still need to consider how you'll take money out. The overall outcome depends on whether you use salary, dividends, or director's loan repayments and how that interacts with your wider financial situation.

5) Interest rates may be less flexible

Many limited company buy-to-let products are built around fixed-rate structures. That can affect your long-term cost planning and refinancing strategy.

6) Fewer lenders

Not all lenders operate in this space, and each lender will have its own approach to company lending. That can reduce the number of options available.

7) Legal and conveyancing can be more specialist

Company buy-to-let arrangements can involve additional legal steps compared with personal mortgages. Some conveyancers may charge more for this type of work, particularly where specialist experience is needed.

8) Less privacy around company accounts

Limited companies must file accounts and comply with Companies House requirements. Depending on the company's size and how it reports, more information may be visible than you might expect.

9) Restructuring costs

Moving an existing portfolio into an SPV can involve legal and tax considerations (see Restructuring below).

How to set up an SPV that lenders will accept

Most limited company buy-to-let lending is designed around an SPV concept. In simple terms: the company is set up so its activities align closely with the lender's expectations.

An SPV is a limited company set up for the purpose of holding property investment assets. It is usually used to:

• ring-fence the property investment within a corporate structure
• separate the investment from other personal or business activities
• support portfolio planning and future financing

Choosing property-appropriate SIC codes

Lenders often look at the company's registered SIC codes (Standard Industrial Classification codes) to understand what the company is set up to do. If the company's stated activities don't match the lender's view of a buy-to-let business, it can create delays or lead to the application being declined.

Commonly, lenders prefer codes that reflect letting and operating residential property. Common SIC codes used in real estate letting and related activities include:

• 68100 – Buying and selling of own real estate
• 68201 – Renting and operating of Housing Association real estate
• 68209 – Other letting and operating of own or leased real estate
• 68320 – Management of real estate on a fee or contract basis

Using property-focused SIC codes helps align the company's stated business activity with what the mortgage is intended to fund. (See our dedicated SIC codes guide for more detail.)

Why lenders prefer SPV structures

Specialist buy-to-let lenders that work with limited companies may look for structures that are easy to understand and consistent with the intended investment plan. SPVs are often viewed more favourably because:

• Purpose-built structure: the company is set up around property investment rather than broader trading activity.
• Clearer underwriting picture: the company's income and expenditure can be easier to map to the property business model.
• More consistent documentation: lenders may expect a similar set of information across SPV cases, which can reduce friction during assessment.

If the company has unrelated trading activity, it can complicate underwriting because it may be harder to separate the buy-to-let risk from other business risks.

It's also worth noting that not every lender offers the same range of products for limited companies, and each lender's criteria can differ. An SPV structure may therefore be relevant when selecting the right lender panel.

Practical setup steps

Setting up an SPV is usually a multi-step process involving legal formation, company administration and mortgage planning. While the exact steps can vary, a typical overview looks like this:

1. Form the limited company – Register the company and set up the company structure.
2. Choose property-appropriate SIC codes – Use SIC codes that reflect property investment activity.
3. Open a dedicated business bank account – Keep property-related income and expenditure separate for clarity.
4. Appoint directors and shareholders – Ensure the company governance is in place and consistent with the investment plan.
5. Prepare mortgage application information – Gather the documents lenders typically request for limited company lending, such as company accounts/forecasts (where relevant), property details and supporting evidence of the business purpose.
6. Select a lender that supports SPV lending – Different lenders have different approaches to limited companies, so matching the structure to the right lender panel can be important.

Deposit and funding: where the money comes from

SPV mortgages normally require a deposit, and lenders will expect clear evidence of where funds are coming from. Common sources include:

• personal savings moved into the company
• equity released via a remortgage (where relevant)
• gifts from family members (often with lender-specific requirements)
• funds moved from an existing company structure (for example, where a holding or trading company is involved)

Because SPV lending can be more paperwork-heavy, it's worth ensuring the deposit story is easy to evidence and consistent across the application.

If you're planning to use the company specifically for buy-to-let, it's usually sensible to ensure the company's structure and activities are consistent with that intention from the start.

How lenders assess limited company buy-to-let applications

While each lender has its own process, there are common themes in how limited company buy-to-let applications are assessed.

Loan-to-value (LTV)

Maximum LTVs for limited company buy-to-let are often lower than those seen in mainstream residential lending. This can mean a larger deposit is commonly required.

Rental coverage (income vs mortgage payments)

Lenders typically assess whether the rent is likely to provide sufficient coverage for the monthly mortgage cost. This is often expressed as a rental coverage requirement.

Company accounts and trading history

Lenders may review the company's accounts (or projections where appropriate) to understand profitability and cashflow.

Company and director information

Even though the borrower is the company, lenders may still request information about the directors—particularly where the company is newly formed or where risk factors exist. Depending on the case, lenders may also look for additional assurance around repayment.

Where a director's guarantee is part of the mortgage, lenders may also consider the director's position as part of the overall risk assessment.

Portfolio size, experience and concentration

Some lenders prefer established landlords or entities with a track record. Others may consider new entrants depending on the overall risk profile. Where portfolio size is relevant, lenders may apply their own limits based on total exposure and concentration.

Lenders may apply additional stress testing, particularly where the borrower already has a portfolio. This can affect the maximum borrowing available.

Property type and tenant profile

Many property and tenancy considerations mirror standard buy-to-let practice, such as:

• property condition and construction
• whether the tenancy is standard or more specialist
• tenant type and any restrictions that may apply

Availability can vary for niche property types, including HMOs.

Newly formed SPVs

It may be possible to obtain limited company buy-to-let lending through a newly formed SPV. However, a new company may be viewed as higher risk because it has no established rental track record.

As a result, lenders may look for one or more of the following:

• a larger deposit and/or additional security
• stronger evidence of expected rental performance
• additional support from individuals connected to the company in some cases

If the company is already trading and has rental history, lenders may be able to assess performance more directly.

Limited company buy-to-let vs personal buy-to-let

The decision often comes down to how you want to structure the investment and how you expect the costs and risk to be managed.

Personal buy-to-let may suit landlords who want a simpler setup and whose personal financial profile is straightforward.

Limited company buy-to-let may suit landlords who want a structured approach to holding property, potentially with different tax and accounting treatment, and who are prepared for the additional company administration and possible personal guarantees.

Restructuring: moving existing property into a company

Many landlords considering limited company buy-to-let are not buying new—they are thinking about moving existing properties into a company.

Moving property from personal ownership into a limited company can involve:

• potential stamp duty land tax considerations
• potential capital gains tax implications
• additional legal and administrative steps

SDLT is generally calculated based on the property's market value at the point of transfer, and moving property into a company may be treated as a disposal for tax purposes.

Because the outcome depends heavily on your circumstances and timing, restructuring is usually something to plan carefully rather than treat as a quick fix. (See our dedicated guide on remortgaging a personal buy-to-let into an SPV for the practical mechanics.)

Running the company after completion

Once the mortgage is in place, the company must be run properly. Lenders and stakeholders expect accurate records and timely compliance.

Ongoing Companies House and HMRC responsibilities

A limited company has continuing administrative duties, including filing requirements and keeping company information up to date.

Director and share changes

If there are changes to directors, shareholdings, addresses, or other key details, these may need to be reflected in the company's records. Keeping information current helps avoid avoidable complications.

Accounting accuracy matters

Lenders typically want to see clear evidence of rental income, costs, and the company's ability to service the mortgage. Poor record-keeping can affect both underwriting and future reviews.

Tax and SDLT considerations (high level)

Limited company buy-to-let can involve tax and stamp duty considerations that differ from personal ownership. Common areas landlords review include:

• how rental profits are taxed within a company (corporation tax)
• whether moving property into a company is treated as a disposal for tax purposes
• Stamp Duty Land Tax (SDLT), which is generally calculated based on the property's market value at the point of transfer

Because the tax position depends on the facts (including how the company is set up and how the property is acquired), it's often important to coordinate mortgage planning with specialist tax guidance. (See our dedicated limited company SDLT guide for the rates, the 3% surcharge and reliefs such as Multiple Dwellings Relief.)

Annual Tax on Enveloped Dwellings (ATED)

Where a company owns certain UK residential property valued above specified thresholds, Annual Tax on Enveloped Dwellings (ATED) can apply. Higher-value residential properties held in a limited company or SPV may fall within ATED, with potential reliefs available depending on how the property is used (for example, where it is let on a commercial basis to a third party on a genuine tenancy).

Because the ATED thresholds and reliefs are fact-specific and can change over time, professional tax advice is usually essential when an SPV is purchasing or holding higher-value residential property.

Risks and how landlords typically manage them

Limited company buy-to-let still carries the core buy-to-let risks—most importantly, that rental income may not always cover the mortgage costs.

Common risk areas include:

• void periods (property empty and no rent coming in)
• repairs and maintenance costs
• tenant-related issues that can affect rent collection
• interest rate and affordability pressure if circumstances change

Landlords often manage these risks by maintaining appropriate reserves, using robust property management arrangements, and ensuring rental assumptions are realistic.

Remortgaging a limited company buy-to-let

Remortgaging through a limited company is broadly similar in principle to remortgaging a personal buy-to-let: the lender reassesses the case based on the property, rental performance and the company's circumstances.

In practice, the key differences tend to be:

• the lender's limited company underwriting approach
• the documentation and information required for the company and directors
• the fact that the mortgage is taken in the company's name, so the company's cashflow and rental record are central to the assessment

If you are considering moving property into an SPV (or between companies), it's also important to factor in that this may be treated differently from a standard remortgage, with potential SDLT and legal/tax implications. (See our dedicated limited company buy-to-let remortgage guide for the step-by-step process and costs.)

Who limited company buy-to-let tends to suit (and who it may not)

It may suit

• landlords with larger portfolios or plans to scale
• investors who are comfortable with company administration
• those whose overall tax position may make corporate profit treatment more favourable
• landlords planning for long-term holding and structured refinancing
• those considering a long-term portfolio strategy rather than a short-term hold
• those who expect to manage multiple properties over time
• first-time landlords who want to start with a company structure from the outset
• investors with a clear property investment strategy who prefer a defined business model

It may not suit

• landlords who want a simpler, personal-name approach
• investors who plan to extract profits immediately without considering the tax mechanics
• those with a single small property where the fixed costs of company administration may outweigh benefits
• landlords who are not prepared for lender criteria complexity and the need for structured documentation
• those working with a smaller deposit and needing the most competitive borrowing terms available
• those who expect profits to be modest, making ongoing company costs harder to justify

Decision framework: how to judge whether it's right for you

Before choosing limited company buy-to-let, it's useful to think about:

• Your tax position now and in the future (including how you plan to extract profits)
• Whether the portfolio size and expected profits are likely to justify the extra company costs
• Your exit plan: how you expect to sell and what that could mean for tax
• The mortgage terms available for company borrowing, including deposit and fees
• Whether your investment plan is aligned with the administrative workload of company ownership
• Whether your strategy involves holding and potentially growing the portfolio
• Whether you have modelled the full picture, including how profits will be taken
• Whether you have considered the implications of transferring existing property (if relevant)
• Whether you are comfortable with the likely lender criteria and documentation requirements

If the decision is based only on headline tax advantages, it can be easy to miss the practical costs and constraints that determine whether the structure works in real life.

Frequently asked questions

Do I need an SPV to get a buy-to-let mortgage?

No. It's possible to buy-to-let through personal ownership. However, an SPV can be beneficial if you want a company structure from the start or you're planning a portfolio strategy that suits corporate ownership.

Can I remortgage a property into an SPV?

In many cases, it's possible to move from personal ownership into a limited company structure, but the process involves legal and tax considerations (including potential SDLT and CGT). Whether it's suitable depends on your circumstances and the position of the property and existing mortgage.

Is an SPV mortgage more difficult than a personal buy-to-let mortgage?

It can feel different rather than necessarily more difficult. SPV lending is often assessed through a company-focused lens, so having the right documentation and a structure that aligns with lender expectations can make the process smoother.

What SIC codes should an SPV use?

Property-related SIC codes are typically used, such as 68100 and 68209. Using codes that reflect property investment activity can help keep the company's stated business purpose aligned with the mortgage application.

Can first-time landlords use an SPV?

Yes. Some lenders support first-time landlords using SPV structures, provided the company is set up appropriately and the overall plan is well evidenced.

Summary

A limited company buy-to-let can be a sensible structure for some landlords—particularly those focused on long-term growth and who may benefit from corporation tax treatment on profits. However, it usually comes with higher borrowing costs (depending on the deal) and ongoing admin.

The "right" decision depends on your personal circumstances, portfolio goals, and how the numbers work across tax, fees, and long-term exit planning. For many investors, the most robust approach is to treat the decision as a full strategy review: mortgage affordability, lender requirements, tax position, profit extraction plans, and the practical steps involved in buying or restructuring.
