For many UK property investors, buying through a limited company has become a cornerstone strategy, and for a very good reason: tax efficiency. The big win is the ability to offset 100% of your mortgage interest against Corporation Tax. This is a crucial advantage that individual landlords simply can't access anymore.
So, let's get straight to it. Is setting up a limited company the right move for your property venture? For a growing number of investors, especially those feeling the pinch from Section 24, the answer is a resounding yes. It's become the default route to sidestep the mortgage interest relief restrictions that have hit higher-rate taxpayers so hard.
But it's not a magic bullet. Before you jump in, you need to be clear-eyed about the trade-offs. You're looking at higher initial setup costs and more administrative legwork throughout the year. Mortgages for companies can also be more complex and sometimes carry higher interest rates. Plus, you’ll have legal duties as a director to keep proper records and file annual returns with Companies House.
This isn't just a niche trend; it's a fundamental shift in the market. The statistics are telling. As of early this year, there are now over 400,000 property investment companies in the UK. That’s a staggering 332% increase in just nine years since the Section 24 changes were first announced. If you want to dig deeper into the market data, this detailed Hamptons report is well worth a read.
To make sense of the two paths, it helps to see the core differences side-by-side. This table breaks down how ownership structure impacts everything from your tax bill to your mortgage options.
As you can see, the choice isn't really about which method is objectively "better." It’s about what fits your personal and financial circumstances.
For a higher-rate taxpayer with a decent-sized, mortgaged portfolio, the company structure is almost a necessity to stay profitable. But for a basic-rate taxpayer with a single, unmortgaged property, the extra costs and admin might not be worth the hassle.
Getting this initial decision right is fundamental. The structure you choose will shape your tax liabilities, your administrative burden, and your financing options for years to come. If you need a hand navigating the accounts and compliance for limited companies in the property sector, our team has the specialist experience to guide you.
Let's get straight to it: the decision to buy a house through a limited company really comes down to the numbers. While owning property in your own name feels simpler on the surface, the tax landscape for UK landlords has been completely reshaped. This has made a corporate structure far more appealing, especially if you're looking to build a property portfolio.
The big reason for this shift is a piece of tax legislation known as Section 24. This rule radically changed how individual landlords are taxed on their rental income. Since 2016, tax policies have been phasing out the ability for individual landlords to claim full relief on their mortgage interest. These changes, as detailed in reports like this one on BuyAssociation, have completely altered the financial maths of property investment.
In short, if you own a buy-to-let in your personal name, you can no longer deduct your mortgage interest costs from your rental income before working out your tax bill. Instead, you get a flat 20% tax credit on your interest payments. For anyone paying higher-rate tax, this is a massive financial hit.
Let me show you what this means with a real-world example. Imagine you're a higher-rate (40%) taxpayer. You have a buy-to-let property bringing in £15,000 in rent each year, and your annual mortgage interest costs are £8,000.
Personal Ownership Scenario (with Section 24):
Taxable Income: HMRC now taxes you on the full rental income, not your profit. Your taxable income is £15,000.
Initial Tax Bill: At the 40% rate, your tax liability starts at £6,000 (£15,000 x 0.40).
Tax Credit: You then get your 20% tax credit on the mortgage interest, which is £1,600 (£8,000 x 0.20).
Final Tax Due: Your final tax bill for the year is £4,400 (£6,000 - £1,600).
Your actual cash profit was £7,000 (£15,000 rent - £8,000 interest), but you've just handed over £4,400 to the taxman. That’s an effective tax rate of 63% on your real profit, leaving you with just £2,600.
This is the punishing reality of Section 24 for higher-rate individual landlords. It artificially inflates your taxable income, decimates profits, and can even push basic-rate taxpayers into the higher-rate bracket.
Now, let's run those same numbers, but this time, you buy the house through a limited company. The crucial difference is that a limited company isn't subject to Section 24. It’s a business, and it can deduct all legitimate business expenses—including 100% of the mortgage interest—before calculating its tax.
Limited Company Scenario (Full Interest Deduction):
Taxable Profit: The company deducts the full mortgage interest from the rent: £7,000 (£15,000 - £8,000).
Corporation Tax Bill: The company pays Corporation Tax on this profit. Assuming the current 25% rate, the tax due is £1,750 (£7,000 x 0.25).
Post-Tax Profit: The company is left with £5,250 in post-tax profit (£7,000 - £1,750).
The difference is stark. In this scenario, the limited company structure saves you £2,650 in tax for the year on just a single property. That retained profit can be reinvested to grow your portfolio, pay down the mortgage faster, or simply be held in the company for a rainy day.
Of course, that money is now inside the company. To use it personally, you have to extract it, which brings its own tax considerations. The two main ways to do this are through a salary or dividends.
Salary: Paying yourself a director's salary is an allowable expense for the company, which reduces its Corporation Tax bill. The catch is that you’ll pay personal Income Tax and National Insurance on that salary.
Dividends: You can pay yourself dividends out of the company's post-tax profits. Dividend tax rates are much kinder than income tax rates, and everyone gets a small tax-free dividend allowance each year.
Most property company directors opt for a combination of a small, tax-efficient salary and taking the rest in dividends. This does require careful planning to get right. For a deeper dive into this, you might find our guide on tax advice for small businesses helpful. The key takeaway is that you have control over when and how you take the money out, giving you a level of strategic tax planning that's simply impossible with personal ownership.
Financing is often the biggest hurdle when you're looking to buy property through a limited company. You can't just wander into a high-street bank and expect to get a standard residential or even a personal buy-to-let mortgage. You're entering the world of specialist financial products, and these come with a whole different set of rules.
Limited company mortgages are a different beast entirely. Lenders treat them as commercial loans, which means the application process is far more rigorous. You can also expect to see higher interest rates and more significant arrangement fees as standard compared to personal borrowing.
This strict approach all comes down to risk. From a lender's point of view, a company is a more complex entity than an individual, so they’ll want to put your entire business plan under a microscope before they'll even think about lending you money.
When your company applies for a mortgage, lenders are really assessing the viability of your property investment business. They need complete confidence that the company can comfortably handle the loan repayments using its rental income. This means they’ll be digging into several key areas.
One of the most crucial requirements, and one that catches many people by surprise, is the director's personal guarantee. For most lenders, this is completely non-negotiable, especially when dealing with a new or small property company.
A personal guarantee is a legally binding promise from the directors to pay the mortgage debt if the company can't. This effectively bypasses the 'limited liability' protection for the loan itself, meaning your personal assets—including your family home—could be on the line if the company defaults.
Lenders demand this because a new company often has no trading history or significant assets other than the property it plans to purchase. The guarantee is their safety net.
A successful application goes way beyond just having a good credit score. You need to present a professional case that proves your business is a solid bet. Here’s what lenders will almost certainly ask for:
A Credible Business Plan: This needs to detail your investment strategy. Think property types, target locations, and realistic rental yield projections. It’s your chance to show you’ve done your homework.
Solid Credit Histories: Every single director will have their personal credit history scrutinised. A black mark against one director can easily sink the whole application.
Property Experience: Lenders sleep better at night knowing the directors have been landlords before. If you're a first-time investor, you might face stricter criteria or higher costs.
A Separate Business Bank Account: You must keep your company finances completely separate from your personal money. It’s a basic requirement for both compliance and credibility. Our guide on how to set up a business bank account walks you through the steps.
Think of it this way: you are selling your business idea to the lender. A well-prepared, professional application is your sales pitch.
Trying to navigate the limited company mortgage market on your own is, frankly, a nightmare. It’s a niche area, and many of the best deals aren't even available directly to the public. This is exactly why a specialist mortgage broker is worth their weight in gold.
A good broker who focuses on corporate buy-to-let finance already has relationships with the right lenders. They know the specific underwriting criteria for each one and can match your company’s profile to the most suitable options. This saves you the pain of multiple failed applications, which can damage your credit file.
They’ll also help you package your application professionally, making sure your business plan and financial forecasts tick all the right boxes, which dramatically increases your chances of getting that "yes."
Buying a house through a limited company might sound complicated, but it's really just a series of logical steps. The process isn't the same as buying in your own name; you're setting up a proper corporate structure and using specialist financial products, so a methodical approach is key from day one. If you follow a clear plan, you'll find it much easier to tick all the legal and financial boxes correctly.
This diagram lays out the typical journey, from creating the company right through to getting the keys.
As you can see, it's a linear path. You can't jump ahead. Each stage has to be completed properly before you can move on, which really highlights how important it is to get that initial company setup spot on.
Your first real job is to form the limited company that will legally own the property. This is more than just picking a name off the shelf; you'll be making decisions that directly affect your mortgage application and your future tax bills.
One of the most crucial details is choosing the right Standard Industrial Classification (SIC) code. This little code tells Companies House, HMRC, and, most importantly, lenders what your business actually does. For property investment, you’ll likely need one of these:
68100: Buying and selling of own real estate
68209: Other letting and operating of own or leased real estate
68320: Management of real estate on a fee or contract basis
From experience, most buy-to-let lenders want to see either 68100 or 68209. It’s a clear signal that the company exists to hold and rent out property. Get this wrong, and you could face an instant rejection from a mortgage provider before you’ve even started.
Once your company is officially registered, it's time to assemble your A-team. Trying to handle corporate conveyancing and finance on your own is a classic false economy. It’s a shortcut that often leads to expensive, time-consuming mistakes down the line.
You absolutely need two key professionals in your corner:
A Specialist Mortgage Broker: As we've mentioned, limited company mortgages are a niche market. A broker who lives and breathes this world has the contacts and knows the specific, often unwritten, rules that lenders use to assess applications.
A Solicitor with Corporate Conveyancing Experience: The legal side of a company purchase has more moving parts than a personal one. Your solicitor needs to be comfortable with the extra due diligence checks on the company itself and the director guarantees that are always involved.
Having the right team in place is non-negotiable. An experienced broker can unlock finance you simply couldn't find otherwise, while a sharp solicitor will ensure the legal transfer is watertight, protecting your investment and keeping you compliant.
Working with your broker, you'll formally apply for a mortgage. This means submitting your new company's details, a solid business plan, and the personal financial information of all directors. Be prepared for this, as every director will be asked to provide a personal guarantee.
Once you have a 'Decision in Principle' (DIP) from a lender, you've got a solid budget to work with and can start making offers on properties.
Making an offer through the company is simple. You just make it in the company’s name. From that point on, all the legal and financial paperwork will be addressed to the limited company, not to you personally.
Offer accepted? Great. Now the conveyancing process kicks off. Your solicitor will be in the driving seat, but remember, there are extra layers of complexity here.
The solicitor will do all the usual property searches, but they also have to carry out due diligence on your company. This means checking its registration details at Companies House, confirming the directors have the authority to make the purchase, and poring over the mortgage offer’s specific conditions, like those personal guarantees.
This dual-track investigation—on both the property and the company buying it—can sometimes stretch the timeline a bit. Good, clear communication with your solicitor is the best way to keep things moving.
On completion day, the lender sends the money, and the property officially becomes an asset of your limited company. The kettle can go on, but the work isn't quite over yet.
Your solicitor has a few critical jobs to do after you complete:
Pay Stamp Duty Land Tax (SDLT): This tax bill is the company's responsibility and must be paid to HMRC within 14 days of completion.
Register the Property: The solicitor will update the HM Land Registry to show your limited company as the new owner.
Register the Lender's Charge: They will also formally register the mortgage lender's interest (their 'charge') against the property's title, which secures their loan.
Once these tasks are ticked off, you've officially done it. You’ve successfully bought a property through your limited company. Your focus can now shift from the buying process to the ongoing management and compliance of your new property investment business.
Getting the keys to a property you’ve bought through your limited company is a massive achievement. But don't pop the champagne just yet – the real work is just beginning. This is where your duties as a company director kick in, and they’re a world away from the simple admin of personal property ownership.
You’re now running a fully-regulated business. That comes with a set of mandatory legal and financial responsibilities. Neglecting these can lead to some pretty serious consequences, from hefty penalties and legal headaches to your company being struck off the register entirely.
Think of it this way: you’ve graduated from managing your personal finances to running a small enterprise. The operational demands are a significant step up, and staying on top of your annual duties is non-negotiable.
Every single year, your company has a list of essential filings it must complete. This isn’t just good practice; it’s a legal requirement of operating a limited company here in the UK. Miss these deadlines, and you’ll face automatic fines that grow larger the longer you ignore them.
Your core annual responsibilities include:
Confirmation Statement: This goes to Companies House to confirm that all the company's details on the public record – like directors, shareholders, and the registered office – are still accurate.
Annual Accounts: You'll need to prepare and file a set of statutory accounts with Companies House. These are financial statements that give a clear picture of the company's financial health over the past year.
Company Tax Return (CT600): This is your detailed tax return for HMRC. It's used to calculate your company's profit or loss for the year and, crucially, how much Corporation Tax it owes.
To get these right, you need to be meticulous with your record-keeping from day one. Every bit of rent that comes in and every penny spent on expenses must be logged correctly.
A crucial, and often forgotten, task is maintaining the company's statutory registers. This means keeping an up-to-date internal record of directors, shareholders (members), and any 'persons with significant control' (PSCs). This is your company's official legal logbook, and it must always be accurate.
Let's be blunt. Trying to handle all this company compliance yourself, especially if you don’t have an accounting background, is a recipe for disaster. The rules are fiddly, the forms can be baffling, and the penalties for mistakes are steep. This is precisely why you should budget for professional help from the very start. It’s not a cost; it’s an essential investment.
A good accountant does more than just ensure your paperwork is filed correctly and on time. They bring strategic value. They can help you structure your finances to be more tax-efficient, spot allowable expenses you might have otherwise missed, and help you plan for the future. The money you save in tax and the peace of mind you gain will almost certainly outweigh their fees.
For property investors, a specialist accountant is even more valuable. Someone who genuinely understands the ins and outs of property tax can be a game-changer. They’ll be experts at preparing property business accounts that are not only fully compliant but also optimised for your specific portfolio. It’s about making sure you’re not just meeting your obligations, but running your property business as smartly as possible.
Deciding to buy a property through a limited company isn't a simple tick-box exercise. It's a strategic move that really depends on your personal situation—your tax bracket, your long-term ambitions, and the size of your portfolio. It’s not a one-size-fits-all solution, and you have to be sure the benefits are going to be worth the extra admin and costs.
So, when does it make perfect sense? The clearest case is for higher-rate taxpayers who are building a mortgaged portfolio. These are the investors hit hardest by Section 24, a piece of tax legislation that can turn a profitable rental into a loss-making headache on paper. A limited company neatly sidesteps this problem, allowing you to deduct 100% of your mortgage interest as a business expense.
This structure is almost a necessity if you're serious about growth. By keeping profits inside the company, you can build up a deposit for your next purchase far more quickly than if you were pulling all the money out personally and getting taxed at higher rates.
On the flip side, this route is often a poor fit for a basic-rate taxpayer with a single, low-leverage property. The annual running costs of a company—think accountancy fees for statutory accounts and tax returns—could easily wipe out any small tax advantage you might gain. If you aren't really affected by Section 24, the added complexity is just not worth the hassle.
It’s also rarely a good idea if your plan is to buy a property to live in yourself. If you do this, you’ll either have to pay your own company full market rent or face a hefty Benefit in Kind (BIK) tax bill from HMRC. Neither is a great outcome.
Looking beyond the immediate tax savings, a limited company opens up some powerful long-term planning opportunities, especially when it comes to your estate. Transferring company shares to family members is often much simpler and more tax-efficient than trying to transfer the deeds of a physical property. This makes for much smoother succession planning, helping you pass your assets down to the next generation without triggering huge, immediate tax bills.
Of course, getting your profits out requires some smart thinking. You can't just live off the rental income directly. Instead, you control how and when you take money out, typically through a mix of a small salary and dividends. To really make this work for you, you need to understand the rules around dividend taxation. You can learn more by reading our expert insights on the UK dividend allowance and how to fit it into your personal tax planning.
When you're thinking about buying a property through a limited company, a lot of questions pop up. It's a smart move for many investors, but the details matter. Here are some of the most common queries we get, with straight-talking answers to clear things up.
Yes, you absolutely can, but it’s not just a simple paper-shuffling exercise. You need to treat it exactly like a sale at the property's current market value. This is a crucial point because it can bring some hefty tax implications into play.
Your company will need to pay Stamp Duty Land Tax (SDLT) on the value of the property. On top of that, you, as the individual selling it, could get hit with a Capital Gains Tax (CGT) bill if the property's value has gone up since you bought it. It’s essential to get this planned out properly beforehand.
It's true, the costs are higher than holding property in your personal name. While forming the company itself is cheap – often less than £100 – the real expenses are the ongoing professional fees. You'll need to factor these into your annual budget.
Accountancy Fees: This will be your biggest ongoing cost. You should set aside anywhere from £800 to £1,500+ a year for your annual accounts, corporation tax returns, and Companies House confirmation statement.
Legal & Mortgage Fees: The conveyancing process is a bit more involved for a company, so it costs more. You might also find specialist mortgage broker fees add to your initial setup costs.
Don’t think of these as just costs. They’re an investment in keeping your business compliant and running smoothly. The money you spend on good advice is almost always less than the penalties you’d face for getting it wrong.
Yes. This one is non-negotiable. Your limited company is a completely separate legal entity from you, and the law requires you to treat it that way. All the company's money—from rent coming in to expenses going out—must pass through a dedicated business bank account.
Mixing your personal and business finances is a huge mistake. It's a practice called ‘piercing the corporate veil,’ and it can completely undo the limited liability protection you set the company up for in the first place, putting your personal assets on the line if things go sour.
