If a large part of your earnings comes from overtime, bonuses or commission, you may wonder whether mortgage lenders will take that income into account when assessing how much you can borrow.

You’ll be pleased to learn that many lenders do consider additional income alongside your basic salary. However, each lender has different criteria, and the amount they are willing to use can vary depending on how regular and reliable the income appears.

Understanding how this works can help you prepare for a smoother mortgage application and potentially improve your borrowing power.

What types of additional income do lenders accept?

Many mortgage lenders are willing to consider income beyond your basic salary, including:

  • Overtime payments
  • Annual or quarterly bonuses
  • Commission
  • Shift allowances
  • Performance-related pay
  • Seasonal overtime
  • Guaranteed overtime

Some lenders are more flexible than others, especially when it comes to applicants working in industries where overtime is common, such as healthcare, construction, emergency services or logistics.

How do mortgage lenders assess overtime income?

Lenders will usually want to see that overtime income is regular and sustainable rather than occasional.

In many cases, they may ask for:

  • The latest three to six months of payslips
  • Recent bank statements
  • Your latest P60
  • Evidence of employment stability

Some lenders may use 100 per cent of your overtime income if it appears consistent over a long period. Others may only use a percentage, such as 50 per cent or 75 per cent, to allow for fluctuations.

For example, if you regularly earn an extra £500 per month through overtime, this could still make a meaningful difference to your affordability assessment.

Are bonuses included in mortgage affordability calculations?

Yes, many lenders will also consider bonuses, especially if they are received consistently.

This is common for people working in sales, finance, management roles and other performance-based positions.

Lenders may look at:

  • How frequently bonuses are paid
  • Whether they are guaranteed
  • Your bonus history over the past one or two years
  • Whether the bonuses vary significantly

Some lenders average bonus income across two years to create a more stable figure for affordability calculations.

What if your income changes from month to month?

Variable income does not automatically prevent you from getting a mortgage. In fact, many lenders now have products designed for applicants with more flexible earning structures. 

The important thing is being able to demonstrate a reliable track record of income over time.

If your overtime or bonus payments fluctuate, working with a mortgage broker can help identify lenders that are more comfortable with variable earnings.

Can overtime and bonuses help you borrow more?

Potentially, yes. If a lender includes additional income within its affordability assessment, this could increase the amount you may be able to borrow. It may also improve your overall mortgage options.

However, lenders will still consider other factors such as:

  • Existing credit commitments
  • Deposit size
  • Credit history
  • Household outgoings
  • Employment stability

Because criteria vary widely between lenders, getting tailored advice can save time and avoid unnecessary applications.

Speak to a mortgage advisor before applying

If you receive overtime, bonuses or commission as part of your income, it is worth discussing your circumstances before applying for a mortgage. A mortgage advisor can help identify lenders most likely to consider your full income and guide you through the process.

Whether you are a first-time buyer, moving home or looking to remortgage, understanding how lenders assess income can help you approach the process with greater confidence.
