The Decision You're Stuck On
You've been self-employed for just over a year. Your income is real, your business is profitable, and you're ready to buy a property — but every mortgage comparison site seems to assume you've got three years of accounts filed and a tidy PAYE payslip. You haven't. So the question is: do you go to a mainstream lender and take what you can get, or do you seek out a specialist lender who will actually read your accounts?
This article compares those two routes directly — mainstream (high-street) lenders versus specialist lenders — across the criteria that matter most when you only have one year of trading history. By the end, you'll know which path fits your situation, and why.
What's Being Compared
- Route A — Mainstream lenders: High-street banks and building societies (think Barclays, NatWest, Halifax, Nationwide) with standard underwriting criteria.
- Route B — Specialist lenders: Challenger banks, specialist mortgage lenders, and private banks that assess self-employed applicants on a case-by-case basis, often accessible only through brokers.
The Criteria Used in This Comparison
- Eligibility — will they lend at all with one year of accounts?
- How they calculate your income
- Maximum loan-to-value (LTV)
- Interest rates and product range
- Speed and ease of application
- Flexibility on income type and structure
Eligibility: Will They Actually Lend to You?
Mainstream lenders
Most high-street lenders require a minimum of two to three years of self-employed accounts. This isn't a soft preference — it's a hard policy threshold baked into their automated systems. Submit an application with just one year of accounts and many will decline at the initial screening stage, before an underwriter has even seen your file.
A handful of mainstream lenders — including some building societies — will consider one year of accounts, but usually only under restrictive conditions: a strong credit score, a substantial deposit (often 25% or more), and a very clean financial history. Even then, the application typically requires a manual referral, slowing the process considerably.
Specialist lenders
Specialist and challenger lenders are explicitly built to accommodate non-standard income. Many will consider borrowers with just one year of completed accounts or, in some cases, 12 months of SA302 returns alongside management accounts. They assess each application individually rather than running it through a rigid scoring matrix. This means a lender can weigh the trajectory of your business — rising turnover, a strong first year, a professional background in your field — rather than simply counting the years you've been trading.
Eligibility here is genuinely broader, though it comes with its own requirements. Lenders will want your accounts prepared by a qualified accountant, your SA302 tax calculations from HMRC, and often a brief narrative from your broker explaining your income structure.
Income Calculation: What Number Do They Use?
Mainstream lenders
Standard lenders typically apply a fixed formula to your income. For sole traders, they use your net profit as shown on your self-assessment. For limited company directors, they typically take salary plus dividends — and they average this figure across two or three years. With only one year available, the averaging formula either fails entirely or produces a misleadingly low figure if your second or third year (which doesn't exist yet) is treated as zero.
This is one of the most damaging aspects of the mainstream route for recent starters. A director who paid themselves £30,000 in salary and £40,000 in dividends in year one has a provable income of £70,000 — but a mainstream lender averaging over three years might assess them at just £23,333.
Specialist lenders
Specialist lenders are far more granular. Many will use your latest year's net profit as the basis for affordability rather than a multi-year average. For company directors, some lenders will go further, assessing salary plus retained profit — not just dividends drawn — which substantially increases the income figure used for the stress test. A director with £30,000 salary and £60,000 left in the business as retained profit could potentially have £90,000 used as their income base, depending on the lender and the deal structure.
Some specialist lenders also accept management accounts, projected income letters from accountants, or 12 months of bank statements as supplementary evidence, giving the underwriter a fuller picture of your earning capacity.
For limited company directors and owner-managed businesses, mortgages for directors and the self-employed require exactly this kind of lender — one that reads the whole picture, not just the salary line.
Maximum LTV: How Much Can You Borrow Relative to the Property Value?
Mainstream lenders
Where mainstream lenders do accept one year of accounts, they typically cap the loan-to-value at 75–80%. That means a minimum deposit of 20–25%. For a £400,000 property, you'd need £80,000–£100,000 in cash. If you're a first-time buyer who's been building your deposit while also building your business, this constraint is likely to rule you out or significantly limit your options.
Specialist lenders
Specialist lenders vary considerably, but the better ones will lend up to 85–90% LTV with one year of accounts, provided the income evidence is robust and the credit profile is clean. Some private banks operating in this space will consider 90% LTV on larger loans for high-earning professionals, particularly those in fields like medicine, law, or technology — where a first year of self-employment often follows a lengthy employed career.
Interest Rates and Product Range
Mainstream lenders
The primary advantage of high-street lenders is their pricing. Because they operate at massive scale and fund through retail deposits, their interest rates are typically lower — sometimes meaningfully so. A borrower who qualifies under standard criteria at a major bank might access rates 0.3–0.7% lower than a comparable specialist product. Over a 25-year mortgage, that difference compounds significantly.
The product range is also wide: five-year fixes, two-year trackers, offset mortgages, and more. But if you don't meet the criteria, none of this matters.
Specialist lenders
Specialist lenders charge a premium for their flexibility. Rates are typically 0.2–0.8% higher than equivalent high-street products, and arrangement fees can be steeper. This is not arbitrary — it reflects the additional underwriting work and the higher perceived risk profile of non-standard income borrowers. For most self-employed applicants with one year of accounts, this is a temporary premium: once you have two or three years of trading history, you can remortgage onto a more competitive product.
Think of the specialist route not as the permanent solution, but as the bridge that gets you into the property in the first place.
Speed and Ease of Application
Mainstream lenders
Applying directly to a high-street bank as a self-employed borrower with one year of accounts is a significant administrative task — even before you discover whether they'll lend to you. You'll fill out long forms, gather extensive documentation, and often wait weeks for a decision, only to receive an automated decline. Without a broker, you have limited visibility into why you were refused and limited ability to challenge it.
Specialist lenders
Specialist lenders are almost exclusively accessible through mortgage brokers. The trade-off is that a good broker will pre-qualify your case before it ever reaches a lender — identifying which of the 100+ lenders in the market will actually say yes to your specific income structure. This dramatically reduces wasted time and needless credit footprint from declined applications. The application process tends to involve more document gathering upfront, but the success rate — when placed correctly — is substantially higher.
Flexibility on Income Type and Business Structure
Mainstream lenders
High-street lenders are largely binary: salary and dividends for directors, net profit for sole traders. Anything else — retained profit, non-standard dividends, mixed employed and self-employed income, income in multiple currencies — tends to fall outside their affordability model entirely.
Specialist lenders
This is where specialist lenders earn their premium most clearly. They can accommodate:
- Sole traders assessed on net profit from one year's SA302
- Limited company directors assessed on salary plus retained profit
- Contractors assessed on day rate (annualised) rather than drawn income
- Professionals with a mix of employed history and new self-employment
- Applicants with seasonal or project-based income patterns
Each of these structures requires a lender who will read a file rather than run a formula.
Who Should Choose Which Route
Choose mainstream lenders if:
- You have a deposit of at least 25% and a clean credit record
- Your income is simple — sole trader, net profit only, no retained profit or dividend nuance
- You're in no rush and willing to approach multiple banks sequentially
- Your SA302 income from one year is high enough to pass affordability at face value, even without averaging
Choose a specialist lender if:
- You have less than two years of accounts and a mainstream lender has already declined you or quoted a figure far below what you need
- You are a limited company director whose salary plus dividends understate your real earnings
- You need 85%+ LTV or are working with a smaller deposit
- Your income structure is anything other than straightforward sole trader net profit
- You want your application placed with the right lender the first time, without accumulating unnecessary hard credit searches
Verdict
Pick mainstream if you have a large deposit (25%+), simple sole-trader income, and the patience to shop multiple banks manually — there's a chance one will accept you, and the rate will be better if they do.
Pick specialist if you have one year of accounts, a limited company structure, a smaller deposit, or any income nuance that falls outside a standard template. The rate premium is real but temporary; the ability to buy the property you want, now, is not.
For most self-employed borrowers in their first or second year of trading, the specialist route — accessed through a whole-of-market broker — is not a compromise. It's the correct tool for the job.
Key Takeaways
- Most high-street lenders require two to three years of accounts; specialist lenders will consider one year, and sometimes less.
- Mainstream income calculations average across multiple years — which produces artificially low figures when you only have one year's data.
- Specialist lenders can use retained profit, not just dividends, which substantially increases borrowing capacity for limited company directors.
- Specialist rates are typically 0.2–0.8% higher than mainstream, but this premium can be shed at remortgage once you have a longer trading history.
- Using a whole-of-market broker protects your credit score by placing your application with the right lender first time, not fifth.

`Frequently asked questions
Can I get a mortgage if I've been self-employed for only one year?
Yes, it's possible — but your options narrow significantly. Most high-street lenders require two or three years of accounts, while specialist lenders will often accept one completed year of self-assessment returns and accounts prepared by a qualified accountant. You'll typically need a clean credit history and ideally a deposit of at least 10–25% depending on the lender.
How do lenders calculate income for self-employed applicants with one year of accounts?
Mainstream lenders usually average net profit (for sole traders) or salary plus dividends (for directors) across two to three years — which produces a very low figure if you only have one year. Specialist lenders often use the latest year's profit directly, and some will include retained profit for directors, significantly increasing the income figure used for affordability.
What documents do I need for a self-employed mortgage with one year of accounts?
You'll typically need your SA302 tax calculation and tax year overview from HMRC, one year of accounts prepared by a qualified accountant, three to six months of business and personal bank statements, and proof of identity and address. Some specialist lenders also accept management accounts or an accountant's letter projecting future income.
Will applying to multiple lenders damage my credit score?
Each full mortgage application triggers a hard credit search, which is recorded on your credit file. Multiple hard searches in a short period can reduce your score and make lenders cautious. Working with a whole-of-market broker means your case is pre-qualified and placed with the most suitable lender first, minimising unnecessary searches.
Are the interest rates higher for self-employed mortgages with one year of accounts?
If you need a specialist lender, expect to pay roughly 0.2–0.8% more than equivalent high-street rates. This reflects the additional risk and underwriting cost. However, once you have two or more years of accounts, you can remortgage onto a more competitive product — so the premium is typically a short-term cost, not a permanent one.
