Remortgaging as a Contractor

How Contractor Income Is Assessed

The way a lender assesses your income as a contractor makes a significant difference to how much you can borrow. There are broadly two approaches used in the UK mortgage market.

Standard self-employed assessment treats you like any other self-employed applicant, using your SA302 tax returns or company accounts. For limited company contractors who take a low salary and top up with dividends, this often results in a low income figure that does not reflect your true earning capacity.

Contractor-friendly assessment, offered by a growing number of lenders, uses your day rate or contract rate to calculate an annualised income. For example, if your day rate is £400 and you work five days a week, the lender may calculate your annual income as £400 multiplied by 5 days multiplied by 46 or 48 weeks (allowing for holidays and gaps between contracts). This typically produces a much higher income figure and a larger borrowing amount.

Which Lenders Are Contractor-Friendly?

Several mainstream and specialist lenders in the UK now offer contractor-friendly mortgage products. These lenders understand the nature of contract work and have adapted their criteria accordingly. To qualify, most require:

• A minimum of 12 months' contracting history — some want two years, while a few accept less if you have relevant industry experience
• A current contract or evidence of a new one — having at least three to six months remaining on your contract strengthens your application
• A day rate that is verifiable through your contract documentation
• Professional qualifications or experience in your field, particularly for IT, engineering, finance, and other skilled sectors

The key advantage of contractor-friendly lenders is that they assess affordability based on your contract rate rather than your tax return income. This means you can often borrow significantly more than you would through a standard self-employed assessment.

Documentation for Contractor Remortgages

Contractor-friendly lenders typically ask for different documentation compared to standard self-employed applications. You should prepare:

• Your current contract showing your day rate, contract duration, and client details
• Previous contracts to demonstrate a track record of continuous work — usually covering the last 12 to 24 months
• Bank statements showing regular income deposits from your contracts
• Your CV — some lenders request this to verify your professional background and experience

If you work through an umbrella company, you will need payslips from the umbrella as well as your underlying contract documentation. Lenders vary in how they treat umbrella income — some use the gross contract rate, while others use the net pay shown on your umbrella payslips.

IR35 and Its Impact on Remortgaging

The IR35 off-payroll working rules affect how your income is taxed and structured, which in turn affects how lenders assess you. If your contract is determined to be inside IR35, you will typically be paid through an umbrella company or your client's payroll, with tax and National Insurance deducted at source.

Some lenders treat inside-IR35 contractors as employed for mortgage purposes, which can actually simplify the application process. You provide payslips and the lender assesses your income in the same way as a standard employed applicant.

For outside-IR35 contractors working through a personal service company, the contractor-friendly assessment based on day rate is usually the most advantageous route. A specialist broker can advise on which approach and which lender will give you the best outcome based on your specific IR35 status.
