Self-employed mortgages have a reputation for being harder than they actually are. The reputation is partly earned: a few high street lenders genuinely do not like irregular income, and the underwriting can be slower. But the broader picture is more positive than the headlines suggest. Whole sections of the market are built specifically around contractors, sole traders, and limited company directors — and lender appetite has expanded steadily over the past decade.
How lenders read your accounts
The first question is which figure they use. For sole traders, it is typically the net profit on your latest SA302, sometimes averaged across two years. For limited company directors, the conventional read is salary plus dividends — but a growing number of lenders now look at salary plus the company's net retained profit, which can transform borrowing capacity for directors who deliberately leave money in the business for tax efficiency.
Contractors get a different treatment entirely
If you work on a day or hourly rate through your own limited company, the most generous lenders will calculate your income as day rate × 5 × 46 weeks. That figure is often considerably higher than salary plus dividends would suggest, and it sidesteps the whole accounts-and-tax-return question. The catch: not every lender offers it, and you usually need at least 12 months of contracting history.
The minimum trading period myth
Most people assume self-employed applicants need three years of accounts. The reality is that many mainstream lenders accept two, several accept one, and a handful will consider applicants who have not yet filed their first set of accounts — provided the business has clear forward visibility (contracts in place, income already flowing). For newly self-employed clients with a strong prior employment history in the same field, one-year options are often realistic.
What matters more than length
Lenders care less about how long you have been trading than about the shape of the most recent period. A profit dip in the latest year — even a small one — can shift you to a lender that takes the lower figure rather than the average. Conversely, a sharp jump in profits can be ignored entirely if the previous year is weaker. Stability and trajectory matter more than peak figures.
Common errors that limit your options
Three avoidable mistakes: drawing down dividends aggressively in the 12 months before applying (which inflates personal tax bills without helping with mortgage figures), changing accountants mid-application, and ignoring the tax year overview alongside the SA302. Lenders increasingly want both. Submitting one without the other invites delay.
The shortest path from complex income to a clear offer is usually the same: tidy paperwork, the right lender for your specific structure, and a few months of consistent figures behind you. None of those are quick wins, but they are all achievable.
