If you are self-employed and looking to buy a home in Cambridge, the mortgage process works differently to a standard employed application. You will not see products labelled “self-employed mortgages” — the products are the same, but the way lenders assess your income is different. This guide explains what lenders look for, how income is calculated depending on your business structure, and what you can do to give yourself the best chance of approval.
Cambridge has a high proportion of self-employed professionals, contractors, and company directors — particularly in the technology, life sciences, and academic sectors. Many earn well above the national average, but the way their income is structured can make mortgage applications more complex than for a straightforward PAYE applicant.
Who Counts as Self-Employed for Mortgage Purposes?
Many lenders treat you as self-employed if you own a material share of the business you work for or have significant control over it. The exact threshold varies by lender. This typically includes sole traders, partners in a business partnership, limited company directors, and freelancers or contractors who operate through their own company.
If you are paid through PAYE and receive regular payslips, you are generally considered employed — even if you work on fixed-term contracts. However, some contractors who work through umbrella companies may face similar documentation requirements to self-employed applicants. The classification can vary by lender, so it is worth checking with a broker.
What Lenders Want to See
The core difference for self-employed applicants is how you evidence your income. Without payslips from an employer, lenders rely on your tax returns and business accounts to assess affordability.
Key Documents
SA302 tax calculations — issued by HMRC, these show your total income and tax due for each tax year. Many lenders look for two years of SA302s, although some will consider one year if your income is strong and stable.
Tax year overviews — these accompany your SA302 and confirm that the tax shown has been paid. Lenders use them to verify the figures on the SA302.
Business accounts — certified accounts prepared by a qualified accountant. Most lenders require at least two years. Many lenders expect the latest accounts to be reasonably recent, often within around 18 months at the point of application.
Bank statements — personal and, in some cases, business bank statements for the previous three to six months.
Proof of upcoming work — if you are a contractor, some lenders want to see evidence of current or upcoming contracts.
You can download your SA302 and tax year overview from your HMRC online account. If you do not have these available online, allow extra time to obtain them from HMRC before starting your application.
How Lenders Assess Your Income
How a lender calculates your income depends on your business structure. Different structures are assessed differently, and different lenders may apply different rules to the same structure.
| Business structure | How income is typically assessed | Key considerations |
| Sole trader | Net profit from SA302, usually averaged over two to three years | Some lenders use latest year if income is rising |
| Partnership | Your share of net profit, averaged over two to three years | Only your individual share is considered |
| Limited company director | Salary plus dividends; some lenders also consider retained profits | Retained profit assessment varies significantly by lender |
| Contractor (day rate) | Annualised day rate calculation with some lenders; others use SA302 | Contract length and continuity matter; evidence of upcoming work may be needed |
Assessment methods vary by lender. A broker can identify which lenders are most favourable to your specific structure and income profile.
Sole Traders
If you are a sole trader, lenders will look at your net profit as shown on your SA302 tax calculation. This is your income after business expenses but before personal tax and National Insurance.
Most lenders average your net profit over two or three years. If your income has been increasing year on year, some lenders may use only the most recent year’s figure, which can increase your borrowing. If your income has declined, lenders may use the lower figure or the average, depending on their criteria.
Limited Company Directors
If you run a limited company, most lenders will assess your income as salary plus dividends drawn from the company. This is the most common approach, but it can understate your actual earnings if you retain profits in the business rather than drawing them as dividends.
Some specialist lenders will consider salary plus net profit (or salary plus retained profit), which can significantly increase the income figure used for affordability. These lenders are primarily intermediary-distributed and are less visible on comparison sites.
This is one of the areas where lender selection matters most for self-employed applicants in Cambridge. Given the property prices here, the difference between a lender that uses salary plus dividends and one that considers retained profits can determine whether a property is within reach.
Contractors
If you work on fixed-term contracts, some lenders will calculate your income based on your day rate multiplied across a working year. This can produce a higher income figure than your SA302 would show, particularly if you have not been contracting for long or if your day rate has recently increased.
For example, a technology contractor on £600 per day would produce an annualised income figure of around £144,000 — which may support borrowing in the region of £648,000 with some lenders, subject to affordability and criteria. This can make a material difference in a market where family homes often start above £400,000.
Not all lenders offer day-rate calculations. Those that do typically want to see a reasonable contract history and evidence of ongoing or upcoming work. Umbrella company workers may be assessed differently again, depending on the lender.
Recently Self-Employed or Less Than Two Years of Accounts?
Most lenders prefer two or three years of trading history, but some will consider applicants with just one year of accounts. Criteria tend to be stricter: you may need a larger deposit, a strong credit history, and evidence that your income is stable or growing.
If you were previously employed in a similar role before becoming self-employed, this can strengthen your application. Some lenders take this continuity of earnings into account when assessing risk.
How to Improve Your Chances of Approval
Use a qualified accountant. Lenders prefer accounts prepared by a chartered or certified accountant. Unqualified accounts may limit your choice of lenders.
Keep your accounts up to date. If your latest accounts are more than 18 months old at the point of application, most lenders may not accept them. Filing promptly gives you more flexibility on timing.
Be aware that lenders assess affordability using the income shown on your SA302s and accounts. If your declared income is intentionally conservative, it can reduce the income figure a lender uses. If this is a concern, your accountant can advise on the wider implications.
Save a larger deposit where possible. A deposit of 10% or more opens up more products and can offset concerns about income variability.
Maintain a clean credit record. Late payments, defaults, or high levels of unsecured debt can make it harder to get approved. This applies equally to employed and self-employed applicants.

Why a Broker Matters for Self-Employed Mortgages in Cambridge
Self-employed mortgage applications involve more judgment than employed ones. Lenders differ in how they assess income, what documents they accept, and how they treat things like retained profits, day rates, and short trading histories.
A whole-of-market broker can identify which lenders are most likely to approve your application and which will offer the best terms for your structure. This is especially important for limited company directors and contractors, where the difference between lenders can significantly affect borrowing capacity.
Some specialist lenders are primarily intermediary-distributed, which means they are less visible if you search comparison sites or apply through a high street branch.
Common Reasons Self-Employed Applications Are Declined
Understanding why applications are declined can help you avoid common pitfalls. Frequent reasons include: accounts that are too old or incomplete, a recent drop in declared income without explanation, applying to a lender whose criteria do not suit your business structure, adverse credit such as missed payments or defaults, and insufficient deposit for the LTV the lender requires. In many cases, a decline from one lender does not mean you cannot get a mortgage — it may simply mean the application landed with a lender whose criteria is not well matched to your structure. A broker can help you avoid this by matching your profile to the right lender before you apply.
Frequently Asked Questions
Can I get a mortgage if I am self-employed?
Yes. Being self-employed does not prevent you from getting a mortgage. The products available to you are the same as those for employed applicants — the difference is how your income is evidenced and assessed.
How many years of accounts do I need?
Many lenders look for two years, though some accept one year with a larger deposit and strong income evidence. Three years of accounts can improve your options further.
Do lenders use my salary, dividends, or net profit?
This depends on the lender. Most use salary plus dividends for limited company directors. Some also consider retained profits, which can increase your assessed income. A broker can match you with the right lender.
How much can I borrow if I am self-employed?
Borrowing is often assessed using an income multiple alongside detailed affordability checks. The key variable for self-employed applicants is which income figure the lender uses. For an indication of borrowing at Cambridge price points, see how much you can borrow.
What is an SA302?
An SA302 is a tax calculation issued by HMRC that shows your total income and tax due for a given tax year. It is one of the main documents lenders use to verify self-employed income. You can download it from your HMRC online account.
I minimise my income for tax purposes — will that affect my mortgage?
It can. Lenders assess affordability based on the income shown on your SA302 or company accounts. If you have structured your finances to minimise declared income, this will reduce the amount you can borrow. Some lenders are more flexible than others, and a mortgage broker can help you find the best fit.
