Mortgages for CIS Contractors

For CIS contractors in the UK, securing a mortgage can be more complex than for traditional employees. Most lenders are geared towards fixed salaries, which can make it difficult for subcontractors working under the Construction Industry Scheme (CIS) to demonstrate consistent income.

However, many specialist lenders and brokers understand CIS income and assess affordability differently. Instead of relying solely on payslips or tax returns, they often use your contract rate or CIS earnings to reflect your true income and borrowing potential.

What are mortgages for CIS contractors?

Mortgages for CIS contractors are designed for subcontractors whose income is paid under the Construction Industry Scheme. As CIS workers typically have tax deducted at source and may not have a fixed salary, lenders use alternative methods to assess affordability.

In many cases, lenders will review your CIS payment history, contracts, or average earnings to calculate your annual income. This approach provides a more accurate reflection of your financial position compared to traditional employment-based assessments.

How CIS contractor mortgages work

CIS contractor mortgages work similarly to standard mortgages, but with a different approach to income verification.

• Your CIS income and payment history
• Your average earnings over time
• Your work consistency and contract continuity

Your income may be annualised based on your earnings. For example:

£400 per day × 5 days × 48 weeks = £96,000 estimated annual income

This estimated income is then used to determine how much you can borrow, typically in the range of 4 to 4.5 times your annual income, depending on the lender and your financial profile.

Why CIS contractors need specialist mortgage support

Standard mortgage applications are designed for salaried employees, which can create challenges for CIS subcontractors.

• Income may appear inconsistent on paper
• CIS deductions can reduce visible net income
• Some lenders may not fully understand CIS structures

Specialist lenders and brokers address these issues by assessing your gross earnings and overall income pattern, rather than relying on traditional employment metrics.

Types of mortgages available to CIS contractors

Fixed-rate mortgages

Provide a fixed interest rate for a set period (typically 2–5 years), offering predictable monthly payments.

Variable-rate mortgages

Rates can change over time depending on the lender’s variable rate or wider market conditions.

Tracker mortgages

Linked to the Bank of England base rate, meaning your payments will rise or fall with interest rate changes.
