Quick Summary

Whilst many lenders consider bonus and commission income, most require it to be regular, sustainable, with a lengthy history of payments.

Thankfully, not every lender is the same, and some are far more flexible than others.

Three main things to note:
1. If your income is one-off or highly variable, only a few will accept up to 100% of it, others reduce this to 80 or 50%, and some won’t accept it at all.
2. Lenders calculate differently, too; some will average the last 3–6 months, and others consider a full 12 months.
3. Most lenders also prefer you to have some level of basic salary, but some are fine with 100% commission or bonus income alone.

The good news – there are at least 35 lenders from the whole market who are more flexible with commission, and over 61 lenders that consider bonus income, all with different variations to their policy in what they will and won’t accept, so finding the best deal from these usually needs some expert input.

Yes, it’s possible. Most lenders will let you put bonus or commission income towards your mortgage, although not all of them will allow 100% of this type of income to be counted towards your overall earnings figure (see the lending criteria section below for more details). Whether you’re approved or not will depend on various factors, such as how regularly you receive additional income and the total amount you receive.

If, for example, most of your income comes from bonuses or commissions, you may find getting approved for a mortgage hard.

However, if you earn a similar amount in bonus and commission income each month on top of your base salary, you’ll typically be viewed more favourably. Lenders will still carry out a thorough affordability assessment to ensure you can afford your mortgage repayments if you missed your targets and didn’t receive any additional income for a period of time.

The key criteria lenders will look at are these:

  • The percentage of total income that’s derived from bonuses/commissions
  • How often are you paid (weekly, monthly, quarterly, annually, one-off)?
  • Are you contractually guaranteed or discretionary?

As well as the above, the following are some of the things lenders will want to know before you apply:

  • What portion of your total income is derived from bonuses and commissions?
  • What is your basic salary (if any)?
  • Your earnings over the past 2 years

Many people wrongly assume that earning mainly through commission or bonuses puts a mortgage out of reach. In reality, with the right guidance to package your income clearly and prove its consistency, you can turn what looks complicated into a straightforward approval.

Again, most lenders are happy to consider overtime income when assessing affordability. However, they’ll base their lending decision on how much overtime income you receive, how often you receive it, and whether overtime is guaranteed in your line of work.

Yes, you can get a mortgage if all of your income is from commission, but it may limit your lender options. Some lenders are comfortable with 100% commission-based income, especially if it’s regular and backed by at least 12 months of evidence. Working with a broker can help you find the right lender who understands your income structure.

Yes, it’s possible to get approved for a buy-to-let mortgage with additional income. However, lenders may apply stricter criteria, such as landlord experience, proof of a clean credit record, and age limits.

There are a few lenders who won’t accept any bonus or commission income at all. Some others cap the amount an applicant can include in their application, for example, at 50% or 60%. Others will accept 100% commission or bonus income.

Lenders need as much assurance as possible that borrowers will be able to meet their monthly repayments, and it isn’t always easy to determine when an applicant’s income is non-standard and possibly fluctuating.

While each lender will have its own set of lending criteria, they’ll typically look at:

Suppose all or most of your earnings come from commissions or bonuses. In that case, you may find getting accepted for a mortgage tricky because lenders will be concerned about your inconsistent and fluctuating income. They’ll worry that a missed target may impact your ability to pay your mortgage. However, that’s not to say you can’t get a mortgage. You may have to use a specialist lender.

If your commission or bonus income is a small part of your overall earnings, getting approved should be more straightforward (as long as you meet all other lending criteria).

Lenders will want to know how regularly you receive your commission or bonus income.

Some will only accept annual payments, while others will accept monthly or quarterly payments. The rationale here is that you should be able to budget better if the payments are consistent and you know when you’ll receive the additional income.

Some lenders will require you to have earned commission or bonus income for 2-3 years before they’ll consider it. However, others will accept 12 months if you can prove the payments are regular and consistent.

It’s worth noting that some lenders will calculate your commission or bonus income as an average over 2 years. So, earning more additional income in year 1 and less in year 2 could reduce the overall amount they’ll consider.

This is particularly relevant to overtime. Some professions guarantee a certain amount of overtime. If this is the case and you can prove it, lenders may view you more favourably.

How to get a mortgage based on bonus or commission income

Here’s a summary of the steps you need to take to apply for a mortgage with bonus or commission income.

Step One: Speak to a broker

For mortgage applicants using bonus or commission income, seeking advice from a broker can make a real difference in terms of cost and efficiency.

Experienced brokers specialising in this niche will know which lenders accept supplemental income and how much they will accept, saving you both the stress and expense of wasted applications.

They’ll also be able to find you the best deal for your circumstances, access exclusive rates often not available to the general public, and guide you through the application, ensuring you have all the necessary documentation.

We have brokers in our network with years of experience helping applicants using bonus or commission income get approved for a mortgage. Contact us, and we’ll match you with an expert today.

Step Two: Ask your employer for a confirmation letter

Lenders may also request a letter from your employer confirming your bonus or commission structure and possibly a forecast of what you should expect to receive. Turnaround time for these types of letters can be long, so it’s best to get your request in early on in the process.

Step Three: Get your documents in order

If you include bonus or commission income in your application, lenders will require proof of how much you receive and how regularly you receive it. That means you’ll need to have all up-to-date paperwork readily available, including payslips, bank statements and the past year’s P60. Not having the relevant documentation ready to go could slow down the application process and could even harm your chances of getting approved.

Which lenders let you declare this income?

Many mainstream and specialist lenders let you declare bonus, commission and overtime income.

These include big names such as Nationwide, Natwest, and HSBC, specialist lenders such as Bluestone, Together, and Vida Home Loans, and challengers like Virgin Money and Aldermore.

Remember, all lenders have their criteria, which can change anytime. A broker is best placed to advise which is best for your circumstances.

How to prove bonus and commission income on your application

As mentioned above, lenders will ask for any bonus or commission income proof. This will typically be in your recent payslips, bank statements or your latest P60. They may also request a letter of confirmation from your employer verifying the bonus or commission structure you’re on and when you’re due to receive your additional income.
