Limited company BTL mortgages typically require higher deposits and stricter affordability checks than residential mortgages. Lenders assess rental income against stress-tested rates and apply stricter criteria for portfolio landlords or complex company structures.
## Mortgage Overview
A limited company buy-to-let mortgage is a specialist landlord mortgage designed for property investors purchasing or remortgaging rental properties through a limited company — usually a Special Purpose Vehicle (SPV) registered with Companies House. These mortgages are not regulated by the Financial Conduct Authority (FCA) as they’re considered business loans.
Unlike residential mortgages, where affordability is based on personal income, limited company BTL mortgages focus on the rental income potential of the property. Lenders assess whether the expected rent covers the mortgage payments by 125% to 145%, using a stress-tested interest rate.
There are various product types available:
– **Fixed-rate mortgages:** Offer stability over 2, 5, or 10 years
– **Tracker mortgages:** Follow the Bank of England base rate
– **Variable-rate mortgages:** Subject to lender’s standard variable rate (SVR)
These mortgages are ideal for:
– **Portfolio landlords** managing multiple properties
– **Higher-rate taxpayers** looking to mitigate Section 24 tax changes
– **Investors seeking long-term growth** through a tax-efficient structure
In 2025, lender appetite for limited company BTL lending remains strong, but with increased scrutiny due to regulatory tightening and affordability pressures.

## Eligibility & Criteria
Lenders apply specific eligibility criteria for limited company buy-to-let mortgages. Here’s what you need to know:
### Income Requirements
While personal income is less important than for residential mortgages, some lenders still require a minimum personal income (typically £25,000+). Others may accept lower or no income if rental income sufficiently covers the mortgage.
### Rental Coverage & Stress Testing
Rental income must cover the mortgage by 125% to 145%, depending on the borrower’s tax status and product type. Lenders use a stress-tested interest rate (usually 5.5% – 7%) to ensure affordability even if rates rise.
For example, if your expected monthly rent is £1,000, and the lender requires 145% coverage at 5.5%, the maximum loan amount would be calculated accordingly.
### Property Type Restrictions
Most lenders prefer standard buy-to-let properties. Restrictions may apply to:
– HMOs (houses in multiple occupation)
– Multi-unit freehold blocks
– New-build flats
– Ex-local authority properties
Specialist lenders may consider these with higher deposits or stricter terms.
### Credit Score Expectations
A good credit history is essential. While some adverse credit may be accepted, most lenders expect:
– No recent CCJs or defaults
– Clean credit file for the last 3–6 years
– Strong repayment history on existing mortgages
### Age & Employment Status
Most lenders set minimum and maximum age limits (e.g., 21–85 at term end). Employment status matters less than rental income, but self-employed applicants may need to provide additional documentation.
### Portfolio Landlords
If you own four or more mortgaged properties, you’re classed as a portfolio landlord. Additional criteria apply:
– Full portfolio details (property schedule, rental income, mortgage balances)
– Business plan and cash flow forecast
– Stress testing across the entire portfolio

### Limited Company vs Personal Name
Lenders prefer SPVs with SIC codes related to property letting (e.g., 68209). Trading companies may face limited lender options or higher scrutiny.
### Regulatory Compliance
You must comply with:
– **Right-to-Rent checks** (for tenants)
– **Selective licensing** (in certain councils)
– **EPC requirements** (minimum rating of E, rising to C proposed for 2028)
## Costs & Affordability
Understanding the true cost of a limited company buy-to-let mortgage is essential for profitability.
### Fees Breakdown

– **Valuation fees:** £300–£1,000+, depending on property value
– **Legal fees:** £800–£1,500+ (specialist solicitors often required)
– **Broker fees:** £500–£2,000 depending on complexity

### Rental Income Calculations
Lenders use projected rental income from a letting agent or surveyor. The amount must meet the required rental coverage ratio after applying the stress-tested interest rate.
### Tax Implications
– **Section 24** restricts mortgage interest relief for personal landlords
– Limited companies can still deduct mortgage interest as a business expense
– Corporation tax applies to profits (currently 25% for most companies in 2025)
