How to get a self-employed mortgage using net profits

A self-employed mortgage is usually assessed using the income a lender can reasonably rely on. For many self-employed borrowers, that means using net profits from the business rather than a traditional employment salary.

This guide explains what “net profit” means in mortgage terms, how lenders typically calculate it, what evidence is commonly required, and the factors that can influence how much you may be able to borrow.

What is a net profit mortgage?

A net profit mortgage works like any other mortgage in terms of affordability and lending checks. The difference is how income is assessed.

Instead of using PAYE payslips, lenders look at the net profit your business generates—generally after deducting allowable business expenses.

In practice, this can be helpful if your business income is not paid to you as a regular salary, or if your drawings/dividends don’t reflect the underlying profitability.

Are self-employed mortgages calculated using gross or net profits?

Both approaches exist, but net profit is often the more common route.

• Net profit: income is based on profit after expenses.
• Gross profit: income is based on profit before certain costs/expenses.

Because lender methods vary, the “best” approach is often the one that matches how your accounts are prepared and how your business operates.

Who can use net profits to apply?

Net profit income can be considered for a range of self-employed structures, including:

• Sole traders
• Partnerships
• Company directors (in some cases, depending on how the lender assesses director income)

The key point is not just what structure you operate, but whether the lender is willing to treat your business profits as reliable income for mortgage affordability.

How lenders calculate net profit (and why it varies)

Lenders don’t all calculate “net profit” in the same way. Your accounts may be prepared on a particular basis, but lenders often apply their own affordability assessment.

Common themes include:

• Averaging income over time (often using more than one year)
• Adjusting for expenses that may or may not be treated as allowable
• Considering the stability of profits

Because of this, two borrowers with similar businesses can receive different affordability outcomes depending on how their accounts are structured and how a lender interprets the figures.

Net profit mortgages for sole traders

For sole traders, net profit is typically derived from your business accounts by:

1. Identifying receipts/income for the year
2. Deducting business expenses
3. Using the resulting profit figure for affordability assessment

If your profits are expected to change significantly in the near future, it’s important to understand how lenders treat current-year performance versus historical averages.

Net profit mortgages for partnerships

For partnerships, lenders usually want to understand your share of the partnership.

In many cases, lenders will only consider net profit if you have a sufficient ownership/interest level and can evidence it. Some lenders may also have requirements around who must be included on the mortgage application.

Net profit mortgages for company directors

Many lenders primarily assess company directors using salary and dividends. However, some lenders may consider net or retained profits as part of the income picture.

Whether retained profits can be used often depends on factors such as:

• how the company is structured
• how consistently profits are generated
• how the director’s personal income is taken
• the lender’s approach to company accounts

How is affordability assessed using net profits?

Affordability is generally based on the income figure a lender is willing to use, then applying their mortgage affordability rules.

In many cases, lenders assess self-employed income using an average of past years. If your most recent year is higher or lower than the average, lenders may treat it differently depending on their policy.

This is why the same set of accounts can lead to different outcomes across lenders.

How much can you borrow using net profits?

The amount you can borrow is influenced by more than just profit—your deposit, credit history, existing commitments, and the lender’s affordability calculations all matter.

Mortgage providers may use income multiples when calculating borrowing capacity, but the exact approach and limits vary by lender and scenario.

For self-employed borrowers, the practical challenge is not only the multiple—it’s whether the lender is comfortable using the net profit figure they can evidence.

How much deposit will you need?

Deposit requirements generally don’t change solely because you’re self-employed. However, the range of lenders willing to assess net profits can be narrower than the wider market.

As a result:

• minimum deposit expectations may be more restrictive for net profit-focused lending
• product choice can be affected by the deposit level

In many cases, a larger deposit can improve the number of available options.

What evidence of income is required?

To assess net profits, lenders typically require evidence that supports the profit figures claimed.

Commonly requested documents include:

• Business accounts (often covering at least the last two years)
• Tax calculations and/or SA302s (where relevant)
• Bank statements (often for a recent period)

If you’re newly self-employed or your profits fluctuate, lenders may require additional information or may apply a more cautious approach.

If your income is increasing (or decreasing)

When profits rise, some lenders may be willing to consider the latest performance more than others. When profits fall, lenders may focus on the lower average figure.

The way your income trend is treated can make a noticeable difference to affordability.

How business risk affects net profit mortgage outcomes

Lenders often view some trading patterns as higher risk than others. Factors that can influence how net profit is assessed include:

• whether profits are consistent or volatile
• whether the business is established or new
• whether the accounts show a clear trading pattern
• whether there are unusual expenses or one-off items

If you’re planning to apply soon after a change in trading, it can be helpful to understand how lenders may interpret that change.

How a broker can help with net profit mortgages

Net profit lending is a specialist area because lender policies vary widely—especially around what income can be used, how many years are required, and how averages are calculated.

A broker can help by:

• matching your circumstances to lenders that are more likely to consider your net profit figures
• preparing your application in a way that aligns with how lenders assess self-employed income
• reducing the risk of avoidable rejections caused by submitting to lenders with unsuitable income assessment methods

Lender approaches: why some applications succeed and others don’t

Even when you meet the headline requirements, outcomes can differ because lenders may:

• use different income calculation methods
• apply different rules to director/partner situations
• treat the same profit trend differently
• have different requirements around deposits and evidence

This is why “getting a net profit mortgage” often comes down to selecting the right lender for your specific financial picture.

Eligibility considerations beyond net profit

While net profit is central to the affordability calculation, lenders also apply their standard mortgage eligibility checks, which may include:

• loan-to-value (LTV)
• credit history
• age
• property type
• overall affordability including existing financial commitments

Some lenders may also consider additional factors such as asset and liability positions shown in accounts, or whether there is evidence of future work where relevant.

Summary

A self-employed mortgage using net profits is often possible, but the outcome depends on how lenders assess your business profits and how consistently you can evidence them.

Key points to focus on:

• net profit is assessed differently across lenders
• historical accounts and income trends can be central to affordability
• deposit level and evidence quality can affect product availability
• your business structure (sole trader, partnership, director) can change how income is treated

Understanding these factors can help you approach the mortgage process with clearer expectations and better alignment between your circumstances and the lender’s assessment approach.
