If overtime, bonuses or commission make up a significant part of your earnings, it’s natural to worry about how lenders will view your income. Many borrowers assume mortgage lenders only look at basic salary, which can lead to unnecessary concern or missed opportunities. In reality, overtime & bonus income mortgages are very achievable when your income is assessed correctly.

At Rosa Mortgages, we regularly help clients secure mortgages where income isn’t fixed or guaranteed each month. By understanding how your overtime or bonus income works and presenting it properly to the right lenders, we can often help you borrow more than you might expect.

What Are Overtime & Bonus Income Mortgages?

There is no separate mortgage product specifically for overtime or bonus income. Instead, this refers to a standard mortgage where the lender includes variable income as part of the affordability assessment.
Because overtime and bonuses can fluctuate, lenders don’t just look at what you earned last month. They focus on income patterns over time to judge whether earnings are reliable and likely to continue.

Where overtime or bonuses form a consistent part of your income, many lenders are happy to include them.
The key difference lies in how lenders assess risk. Some are cautious and only use a portion of variable income, while others are far more flexible. Choosing the right lender can make a significant difference to the outcome of your application.

Types of Overtime & Bonus Income Lenders May Accept

Lenders often distinguish between different types of variable income. Regular overtime that has been earned consistently with the same employer is generally viewed more favourably than occasional or ad-hoc overtime. Where overtime forms part of your normal working pattern, it may be treated almost like basic income.

Bonus income can also be acceptable, particularly if bonuses are paid annually or quarterly and follow a predictable pattern. Even discretionary bonuses may be considered where there is a clear history showing they are paid regularly.
Commission-based income and shift allowances may also be included, especially where earnings are stable over time. Each income type is assessed slightly differently, which is why lender choice and presentation are so important.

How Do Lenders Assess Overtime & Bonus Income?

When reviewing overtime & bonus income mortgages, lenders usually look at income over a longer period rather than focusing on individual months. This often involves averaging income over six, twelve or sometimes twenty-four months to smooth out fluctuations.
Some lenders are willing to use 100% of overtime or bonus income, while others may only include a percentage. The amount they’ll accept depends on how consistent the income has been, whether it’s guaranteed, and how long you’ve been earning it.

Evidence plays a crucial role. Payslips, P60s and bank statements are typically required to show income history clearly. Where employment has been stable and income patterns are easy to follow, lenders are generally more comfortable including variable income in full.

How Much Can You Borrow Using Overtime & Bonus Income?

Including overtime or bonus income can have a meaningful impact on how much you’re able to borrow. For many borrowers, variable income makes up a large proportion of their overall earnings, so excluding it would significantly limit affordability.

How much you can borrow will still depend on factors such as your credit history, existing commitments and deposit size. However, selecting lenders who fully recognise overtime and bonuses can unlock borrowing potential that might otherwise be overlooked.
At Rosa Mortgages, we calculate affordability carefully and realistically, ensuring any borrowing level is sustainable while still making the most of your income.

How Long Do You Need to Receive Overtime or Bonus Income?

Most lenders want to see a track record before they’ll include overtime or bonus income. This is commonly between six and twenty-four months, depending on the income type and how consistent it has been.
Guaranteed bonuses or contractual overtime are usually viewed more positively, as lenders see them as more predictable. That said, discretionary income can still be accepted where there is a strong, consistent history.
If your overtime or bonus income is newer, it doesn’t automatically mean rejection. Some lenders are more flexible, particularly where your overall income profile is strong.

Can You Get an Overtime & Bonus Income Mortgage with Bad Credit?

It may still be possible to secure an overtime & bonus income mortgage if you’ve had credit issues in the past. Lenders will consider the nature of the credit problem, how long ago it occurred, and how well your finances have been managed since.

Where income is strong and consistent, and recent credit conduct is good, specialist lenders may be more accommodating. We’ll assess your circumstances honestly and guide you towards realistic and appropriate options.
