A complex income mortgage is designed for borrowers who don’t fit the standard lending criteria. If you have income from multiple sources, your earnings fluctuate, or you have a non-traditional way of being paid, many banks may struggle to assess your affordability.

Common situations where a complex income mortgage may be needed include:

✔ Self-Employed Professionals – Business owners, freelancers, and sole traders with variable income
✔ Company Directors – Those who take a low salary but earn through dividends or retained profits
✔ Contractors & Locums – Working on short-term contracts or multiple clients
✔ Bonus, Overtime & Commission Earners – Those with significant variable pay
✔ Landlords & Investors – Individuals with rental income or property portfolios
✔ Multiple Income Streams – A combination of employment, investments, or side businesses

If your earnings don’t fit into a simple monthly payslip, you may need a lender that specialises in complex income assessments.

Every lender has their own criteria, but here’s how they typically assess different types of complex income:

📌 Self-Employed & Business Owners – Lenders often request 2-3 years’ worth of tax returns (SA302s) but some accept just one year if your earnings are stable. Some lenders also consider retained profits in your company, rather than just salary and dividends.

📌 Contractors & Locums – Your borrowing power is usually based on your day rate rather than annual accounts. Some lenders calculate your income as (daily rate × 5 days × 46–48 weeks), which can significantly increase your borrowing amount.

📌 Bonus, Overtime & Commission – Some banks only count 50% of variable earnings, but specialist lenders may accept 100% if it’s regular and provable over 12–24 months.

📌 Rental & Investment Income – If you receive rental income, some lenders only accept a portion of it, while others consider the full amount—especially if you have a strong rental history.

Each lender assesses income differently, which is why it’s important to work with a broker who understands how to present your finances correctly.

Most lenders will allow borrowing of 4-5 times your annual income, but how they calculate that income depends on their policies.

👉 Example 1: Company Director with Retained Profits

• Salary: £12,000
• Dividends: £30,000
• Retained Profits: £80,000
• Some lenders will only consider salary + dividends (£42,000), but others will factor in retained profits (£80,000+), increasing borrowing potential.

👉 Example 2: Contractor on £400 per day

• Works 46 weeks per year
• Some lenders will calculate annual income as £400 × 5 days × 46 weeks = £92,000
• Potential mortgage: £368,000–£460,000

👉 Example 3: Employed Worker with Bonuses & Overtime

• Base salary: £50,000
• Annual bonus: £20,000
• Some lenders only count 50% of the bonus (£10,000), while others accept the full £70,000 income

This shows why choosing the right lender is crucial—it could mean the difference between securing the mortgage you need or being told you don’t earn enough.
