What are the current rules around getting a buy-to-let mortgage through a limited company vs. personally? Everyone seems to say limited company is better for tax now, but what about the mortgage side?
Quick Answer
Limited company Buy-to-Let mortgages, or SPV mortgages, typically have higher interest rates and stricter lending criteria than personal BTL mortgages, but offer tax advantages for some investors due to the absence of Section 24 restrictions.
## Understanding Limited Company BTL Mortgage Differences
Transitioning from personal ownership to a limited company structure for Buy-to-Let (BTL) investments brings distinct considerations, particularly concerning mortgage products and lending criteria. While the tax benefits of a limited company are frequently highlighted, the mortgage landscape for these entities differs significantly from personal BTL mortgages.
### Lending Criteria for Limited Companies
Limited company BTL mortgages, often referred to as Special Purpose Vehicle (SPV) mortgages, involve lending to a company rather than an individual. Lenders typically assess the company's financial standing and the directors' personal guarantees. This means:
* **Higher Interest Rates:** As of December 2025, limited company BTL mortgage rates are generally 0.5% to 1% higher than personal BTL rates, averaging 5.5-7.5% for a 2-year fixed term. This premium reflects the perceived higher risk for lenders dealing with corporate entities.
* **Stress Testing:** The standard BTL stress test of 125% rental coverage at a 5.5% notional rate still applies, but some lenders may apply a higher notional rate for limited companies. This means the property's rental income must cover 125% of the mortgage interest at this higher notional rate, impacting maximum loan amounts (e.g., a property generating £1,000 rent needs to cover £800 in mortgage payments at the notional rate).
* **Director Guarantees:** Lenders almost always require personal guarantees from the directors of the limited company, meaning the individuals are still personally liable if the company defaults. This reduces the 'limited liability' aspect for debt taken on by the company.
* **Product Availability:** The market for limited company BTL mortgages is growing but still has fewer lenders and products compared to personal BTL. This can restrict options for investors with specific requirements or lower equity levels.
### Lending Criteria for Personal Buy-to-Let
Personal BTL mortgages are secured against the individual's assets and income. These typically involve:
* **Lower Interest Rates:** Personal BTL mortgage rates are generally lower, currently ranging from 5.0-6.5% for a 2-year fixed term. This is due to a more established lending market and perceived lower risk for lenders.
* **Stress Testing:** The 125% rental coverage at a 5.5% notional rate is standard, allowing for potentially higher borrowing against the same rental income compared to some limited company products.
* **Individual Affordability:** Lenders assess the individual borrower's income, credit history, and existing financial commitments. This can sometimes be more straightforward than assessing a new limited company.
## Tax Implications and Section 24
The primary driver for many investors considering a limited company structure is the tax treatment of mortgage interest, specifically Section 24 of the Income Tax Act 2007.
### Impact of Section 24
Since April 2020, individual landlords cannot deduct mortgage interest from their rental income before calculating their tax liability. Instead, they receive a basic rate tax credit of 20% on their finance costs. This significantly impacts higher and additional-rate taxpayers, effectively increasing their taxable income.
* **Example for Personal Landlord:** A higher-rate taxpayer with £10,000 rental profit and £5,000 mortgage interest (taxable income £15,000 without interest deduction) would pay tax on the full £10,000, receiving only a £1,000 tax credit (20% of £5,000). Their effective tax bill is much higher.
### Limited Company Tax Treatment
Limited companies are not subject to Section 24. They can deduct all finance costs, including mortgage interest, from their rental income before calculating corporation tax. This makes them significantly more tax-efficient for investors, particularly higher and additional-rate taxpayers.
* **Corporation Tax Rate:** Profits under £50,000 are taxed at 19%, while profits over £250,000 are taxed at 25%. This is often lower than individual higher (40%) or additional (45%) income tax rates.
* **Example for Limited Company:** The same property generating £10,000 rental profit and incurring £5,000 mortgage interest would result in a £5,000 taxable profit (£10,000 - £5,000). At the small profits rate, the company would pay £950 in Corporation Tax (19% of £5,000). Distributions from the company to shareholders are then subject to personal dividend tax.
## Steve's Take
The move to a limited company structure is primarily driven by Section 24 for tax efficiency, especially if you're a higher-rate taxpayer. However, you must factor in the mortgage side. Rates are currently 0.5-1% higher for limited company products, and exit routes for funds can involve dividend tax. It's crucial to weigh the potentially higher mortgage costs and administrative burden against the substantial tax savings on rental income not subjected to Section 24. This isn't a simple choice; it requires financial modelling based on your specific circumstances.
## Actionable Steps for Investors
1. **Consult a Mortgage Broker:** Engage a specialist BTL mortgage broker (search 'limited company BTL mortgage broker UK') experienced with SPV lending. They can provide current rates for both personal and limited company options and assess your eligibility.
2. **Seek Tax Advice:** Speak to a property tax specialist accountant (find one via ICAEW.com or ACCA.org.uk) to model the tax implications for your personal income tax bracket versus a limited company structure, considering Corporation Tax and dividend tax.
3. **Review Lender Criteria:** Understand that each lender has different criteria for limited companies, including minimum loan amounts, maximum LTVs, and director experience requirements. This will be provided by your mortgage broker.
4. **Evaluate Exit Strategy:** Consider how you plan to extract profits from a limited company. While Corporation Tax is lower, dividend tax is applied to profits withdrawn, which impacts overall net returns. Discuss this with your accountant.
5. **Calculate Overall Profitability:** Create a detailed cash flow projection comparing personal vs. limited company ownership. Include all costs: higher mortgage interest, setup fees, accounting fees, and all relevant taxes (income tax, Corporation Tax, dividend tax, SDLT at 5% surcharge for additional properties). This will give a clear financial picture.
