Holding buy-to-let properties through a limited company has become the default strategy for many UK landlords, particularly those who are higher rate taxpayers or building a portfolio. But a limited company structure brings its own rules, costs, and considerations.
This article covers everything South Coast investors need to know before setting up a limited company for BTL investing.
Why investors use limited companies
The primary reason is tax efficiency. Under Section 24, personal name landlords cannot deduct mortgage interest from rental income before tax. Limited companies can. For landlords with significant mortgage debt, this difference alone can save thousands of pounds per year.
There are other advantages too:
– Corporation tax rates (19 to 25 per cent) are lower than higher rate income tax (40 per cent)
– Profits can be retained in the company for future acquisitions without extracting and incurring personal tax
– Legal liability is separated from personal assets
– The company can claim capital allowances on fixtures and fittings
Setting up the company
Setting up a limited company for property investment is straightforward. You register with Companies House, choose a company name, and appoint directors and shareholders. Most investors use a company formation agent online for GBP 10 to GBP 50.
Important structural choices:
– Shares: Most property companies issue ordinary shares. If you invest with a partner, consider whether you want equal voting rights and dividend entitlement.
– Director vs shareholder: You can be a director without being a shareholder, or a shareholder without being a director. The structure determines control and tax treatment.
– Name: Some lenders have restrictions on company names containing certain terms like “property” or “investments”. A simple name like “YourName Properties Ltd” is usually fine.
Opening a business bank account
The company needs a dedicated business bank account. Specialist property finance accounts are available from several lenders, including Virgin Money, Metro Bank, and various challenger banks. The application process requires the company incorporation certificate and proof of identity for directors.
Do not mix personal and company finances. HMRC is strict about this, and a company that operates like a personal account can lose its tax advantages.
Financing limited company purchases
BTL mortgages for limited companies are widely available but come with different terms than personal BTL mortgages.
Typical differences include:
– Interest rates: 0.25 per cent to 0.75 per cent higher than equivalent personal BTL products
– Deposit requirements: Usually 25 to 30 per cent minimum
– Product availability: More lenders offer personal BTL than limited company BTL
– Lender fee: Arrangement fees are often higher
– Personal guarantee: Most lenders require a personal guarantee from the director, meaning you are personally liable if the company defaults
Despite the higher rates, the tax savings from deducting mortgage interest usually outweigh the additional borrowing cost for higher rate taxpayers.
Extracting profits from the company
The company’s rental profits are subject to corporation tax. Extracting those profits for personal use triggers further tax.
The two main extraction methods are:
Salary: A director’s salary is tax-deductible for the company and subject to PAYE. This is tax-efficient up to the personal allowance threshold (GBP 12,570 for 2025-26). Above that, income tax and national insurance apply.
Dividends: Dividends are paid from post-tax profits. They are not subject to national insurance. The dividend allowance for 2025-26 is GBP 500. Above that, dividend tax rates are 8.75 per cent (basic rate), 33.75 per cent (higher rate), and 39.35 per cent (additional rate).
Most landlord-directors use a combination — a small salary to use their personal allowance, plus dividends for additional income.
Retaining profits for growth
One significant advantage of the company structure is the ability to retain profits. If your BTL portfolio generates GBP 20,000 of post-tax profit and you leave that in the company, you can use it for the next acquisition deposit without extracting it and paying personal tax first.
This accelerates portfolio growth. A personal name landlord must pay income tax on profits before saving for the next deposit. A company landlord does not.
VAT considerations
Letting residential property is generally exempt from VAT. Your company cannot register for VAT on rental income, which also means it cannot reclaim VAT on expenses. The VAT on your costs — solicitor fees, survey costs, refurbishment materials — is an irrecoverable cost.
This is the same for personal name landlords. It is not a company-specific disadvantage but is worth understanding.
Selling a company-held property
When a limited company sells a property, it pays corporation tax on the gain, not capital gains tax. The corporation tax rate (19 to 25 per cent) is similar to the residential CGT rate (18 to 24 per cent), so the difference is marginal.
The real difference is that the company can distribute the sale proceeds as dividends, meaning the gain is taxed twice — once as corporation tax and again as dividend tax on extraction. This makes sale from a company less tax-efficient than sale from a personal name.
This is why many company landlords plan to hold properties long-term rather than flip or sell. The structure favours income generation and portfolio growth over short-term trading.
Practical next steps for South Coast investors
If you are considering a limited company structure, here is a practical sequence:
1. Speak to a property accountant about whether incorporation fits your situation
2. Form the company at Companies House
3. Open a business bank account
4. Discuss your borrowing capacity with a BTL mortgage broker
5. Start sourcing properties that match your company’s investment criteria
Portsmouth and Hampshire are excellent markets for company-held BTL. The rental yields support the cost of company financing, and the long-term capital appreciation strengthens the balance sheet over time.
