Can I refinance a buy-to-let property as a contractor?
13th February 2026
By Simon Carr
Refinancing a buy-to-let (BTL) property when you work as a contractor is certainly possible, although the application process can be more complex than for standard salaried employees. Due to the variable nature of contract income, traditional high-street lenders may struggle to assess your affordability, making specialist brokers and lenders who understand day-rate contracts essential for a successful outcome.
Can I refinance a buy-to-let property as a contractor? Understanding Specialist Finance
The UK buy-to-let market offers significant opportunities for investors, but securing or refinancing mortgages can present challenges, especially for those who do not have a traditional P60 salary structure. Contractors, freelancers, and consultants often find themselves in this category. While your income might be substantial and consistent, standard underwriting criteria frequently fail to reflect your financial stability.
For contractors looking to refinance a BTL property—perhaps to raise capital, secure a lower rate, or fund further property renovations—the key is understanding how lenders assess non-standard income and targeting those institutions willing to underwrite based on contract evidence.
Why Contractors Need Specialist BTL Refinancing
Lenders rely on predictable income streams to calculate affordability for BTL mortgages. While the primary calculation for BTL mortgages focuses on rental income coverage (usually requiring the rent to cover 125% to 145% of the mortgage interest payment), the applicant’s personal background income is still required to confirm financial stability and meet stress tests.
The Challenge of Variable Income
Traditional lenders typically assess income using the following standard documentation:
- Two to three years of audited accounts (if trading through a limited company).
- SA302 forms and Tax Year Overviews (if self-employed).
- P60s and payslips (if salaried).
Contractors, however, often operate through their own limited companies, taking income primarily as dividends and a small salary, or they might be paid based on a high day rate without the continuous, predictable annual income shown by a P60. This discrepancy often triggers automatic rejection from automated high-street systems.
The Specialist Lender Solution
Specialist BTL lenders have underwriting teams who understand that a contractor’s day rate is a reliable indicator of earnings potential. Instead of relying solely on historic accounts, these lenders typically calculate affordability by:
- Annualising your current day rate (e.g., Day Rate x 5 days x 46 weeks).
- Requiring evidence of a consistent track record (often 6 to 12 months in the current contracting field).
- Focusing on the strength and longevity of the current contract.
By working with a specialist broker who has established relationships with these specific lenders, you can streamline the process significantly.
Key Documentation for Contractor Refinancing Applications
To successfully demonstrate your financial position and overcome potential underwriting hurdles, a contractor should prepare a robust application package. While specific requirements vary between lenders, the following documents are typically requested:
- Current and Previous Contracts: Lenders usually require your current contract plus evidence of previous contracts covering the last 6 to 12 months. This proves the continuity of your work.
- Bank Statements: Personal and business bank statements, usually covering the last three to six months, demonstrating consistent receipt of contract income.
- CV/Professional History: Some lenders use your comprehensive CV to assess the depth of your experience and the likelihood of securing future contracts quickly.
- SA302 Forms and Tax Overviews: Even if your primary income assessment is based on your day rate, providing recent tax documentation (SA302s) confirms good tax standing with HMRC.
- Proof of Deposit/Equity: Evidence that you have the required equity in the BTL property (often required for loan-to-value calculations) or funds if capital raising.
A crucial factor in any refinancing application is your personal credit history. Lenders will perform comprehensive searches to assess your reliability in meeting past debt obligations.

Understanding Loan-to-Value (LTV) and Affordability
When refinancing, two metrics are paramount: the Loan-to-Value (LTV) ratio and the Interest Cover Ratio (ICR). Contractors must ensure both the property finances and their personal finances meet the lender’s criteria.
The Interest Cover Ratio (ICR)
The ICR confirms that the rental income generated by the property is sufficient to cover the mortgage interest payments, typically stressed at a higher rate (e.g., 5.5% or 6%). If the rent falls short of the required ICR, some specialist lenders may allow you to use your strong contractor income to ‘top up’ the affordability gap. This is known as a background income contribution or top-slicing.
Loan-to-Value (LTV)
LTV is the ratio between the mortgage amount and the current valuation of the property. If you are refinancing for a better rate, you may aim for a lower LTV band (e.g., 60% or 65%), which usually unlocks better rates. If you are raising capital (releasing equity), you might be looking towards higher LTVs, potentially up to 75% or 80%, depending on the lender and your contractor status.
People also asked
How long do I need to be contracting to get BTL finance?
While some high-street lenders require 24 months of trading history, many specialist contractor lenders will consider applicants with just 6 to 12 months of consistent contract work, provided the current contract is long and stable, often requiring minimum remaining term of three months.
Does it matter if I contract through a limited company or umbrella company?
Lenders treat these structures differently. If you operate through a limited company, assessment is usually based on the annualised day rate and evidence that the company is solvent. If you use an umbrella company, lenders often treat your income as closer to a standard employee, focusing on payslips and employment history.
Can I refinance if my BTL property needs refurbishment?
If the property is currently unmortgageable (e.g., lacks a functioning kitchen or bathroom), you typically cannot secure a standard BTL refinance until the work is complete. In this scenario, bridging finance is often used to fund the refurbishment, followed by a standard BTL refinance once the property meets habitable standards.
What interest rates can contractors expect on BTL refinancing?
Contractors with long, stable contracting history and clean credit profiles can often access rates competitive with those offered to salaried individuals, particularly if the LTV is low (60% or less). However, if your history is shorter, or if you require top-slicing due to low rental coverage, rates may be slightly higher to reflect the perceived increased risk.
Do I need to live in the UK to refinance a BTL property as a contractor?
It is significantly easier to refinance if you remain a UK resident, as the lending criteria and affordability checks are simpler. Non-resident contractors looking to refinance UK BTL properties will require dedicated non-resident BTL mortgages, which involve further documentation regarding tax status and global income, usually through specialist lenders.
Summary of the Contractor Refinancing Process
Successfully refinancing your buy-to-let property as a contractor relies heavily on preparation and expertise. The initial hurdle of demonstrating stability can be overcome by compiling excellent documentation that highlights your consistent day rate and contract history.
By bypassing traditional high-street options and engaging with specialist lenders and brokers who understand contract finance, you can secure competitive BTL refinancing, enabling you to continue building your property portfolio and managing your assets effectively.
