Contractor Mortgages Explained: What Counts as Income?

Posted on

One question often comes up again and again: "What actually counts as income for a contractor when applying for a mortgage?"

How lenders assess your earnings can dramatically impact your borrowing power. Below, we break down exactly what mortgage lenders look at...

‍

How Lenders View Contractors

‍

Contractors are notassessed like self-employed borrowers. In fact, lenders generally treat contractors more like employed applicants.

‍

How Contractors Are Assessed for Mortgages

Lenders focus on:

‍

  • Your current contract
  • Your day rate or fixed-term salary
  • Your contract history

‍

They then annualise your contract rate to work out your income so your borrowing power reflects your current earning level, not past tax records.

‍

Self-employed applicants are assessed on 1–3 years of tax returns and business accounts, not their current contract value.

‍

The Key Difference:

Contractors are assessed on the strength of their current contract.Self-employed borrowers are assessed on past financial performance.

That’s why contractors often qualify for higher lending, because lenders recognise their present earning power rather than historical accounts.

‍

‍

What Counts as Income for Contractors?

‍

This is the foundation of most contractor mortgage calculations.

‍

Lenders typically use:

Day rate × 5 × 48–52 weeks = Annualised income

Depending on the lender, they may use 46 weeks (more conservative) or the full 52 weeks.

‍

This often means contractors can be assessed at significantly higher income levels than their PAYE counterparts.

‍Example:£650/day × 5 × 48 = £156,000 annual income

‍

‍

Fixed-Term Contract Salary

‍

If you’re on a PAYE contract with a set annual salary, the lender will usually treat this exactly the same as a permanent employee’s income.

If your contract includes renewal clauses or you’ve been contracting continuously, this strengthens your profile further.

‍

Bonuses

‍

Many high-earning contractors receive bonuses on top of their rate.

Here’s how lenders treat bonuses:

‍

  • Guaranteed bonuses can often be included at full value
  • Regular annual bonuses may be averaged over 1–3 years
  • Ad-hoc or performance-based bonuses may be included at a reduced percentage

‍

If you have strong evidence of bonus history, it can boost your borrowing power significantly.

‍

Allowances

‍

Some lenders accept:

‍

  • Travel allowances
  • Housing allowances
  • Living stipends
  • Contractual expense payments

‍

As long as they appear consistently on your contract or payslips, these can often be factored into affordability.

‍

Overtime or Extended Hours

‍

If your contract includes paid overtime or extended day rates for longer shifts, lenders with contractor-friendly policies may incorporate this into your assessed income.

‍

What Doesn’t Count as Contractor Income?

‍

To avoid surprises, here’s what lenders usually won’t include:

‍

  • Irregular one-off project payments
  • Reimbursed expenses
  • Company dividends (unless you run a limited company as a true self-employed borrower)
  • Anything not evidenced on a contract or consistent payslip history

‍

If you’re unsure whether a payment counts, we can review your documents and assess it instantly.

‍

How Long Do You Need to Be Contracting to Get a Mortgage?

‍

Many lenders will consider you with:

‍

  • As little as 1–3 months in your current contract, and
  • A contracting history of 6–12 months, OR
  • A strong employment track record in the same field

‍

Renewals, extensions, and previous contracts all help demonstrate stability.

‍

How to Strengthen Your Contractor Mortgage Application

‍

To maximise your borrowing power:

‍

  • Keep contracts organised – including extensions and renewals
  • Maintain at least 3–6 months of bank statements showing day-rate income
  • Avoid long gaps between contracts where possible
  • Gather bonus evidence if applicable
  • Use a broker who understands contractors — it makes a huge difference

‍

Contractors often underestimate how much they can borrow. Because lenders annualise your day rate and consider additional income streams like bonuses and allowances, your affordability can be far higher than a typical PAYE employee earning the same monthly take-home.
