A person earning £150,000 of business profit can get assessed for anything from £35,000 to £150,000 of "mortgage income" depending purely on how their business is structured and which lender they apply to. This is the most expensive freelancer mortgage decision you can get wrong — and the easiest to fix if you know which lender to ask. Here's how the three main income-assessment routes compare for the same person, the same profit.
TL;DR
- Sole trader — lenders use SA302 net profit. Simple, broad lender access, no specialist route needed.
- Ltd (standard route) — salary + dividends drawn. Penalises tax-efficient setups where you retain profit in the company.
- Ltd (retained profits route) — salary + share of company net profit (incl. retained). Specialist lenders only. Often 2–4× more borrowing than the standard Ltd route.
How each structure is assessed
Sole trader assessment
You file Self Assessment annually. Your SA302 shows your net profit (turnover minus allowable expenses). Lenders use that figure — typically averaging the latest 2 years, or using the lower of two if your income dropped.
What lenders want to see:
- SA302s for the relevant years
- Matching Tax Year Overviews
- Latest 3–6 months of personal and business bank statements
- Evidence of continuing trade
Most UK high-street lenders have a sole trader route. Multiples and rates are standard.
Ltd director — standard route (salary + dividends drawn)
This is what most high-street lenders apply by default. They look at:
- Your gross director's salary
- Dividends actually paid out to you in the same period
- Typically 2-year averages (or lower of two years if income dropped)
Retained company profit doesn't count under this route. So a director who runs an efficient tax setup — small salary, modest dividends, retain the rest in the company — gets assessed on a fraction of their actual business performance.
Ltd director — specialist route (salary + retained profits)
A smaller panel of lenders looks at your share of company net profit — whether you drew it or not. The assessment becomes:
- Director's gross salary
- Plus your share of company net profit (your equity stake × net profit, e.g. 100% × £150,000 = £150,000 for a sole director)
- Typically 2-year averages
Lenders that operate this route: Halifax (via brokers), Clydesdale, Saffron Building Society, Kensington, Aldermore, Vida Homeloans, Coventry (in some scenarios), Skipton. Common requirement: an accountant's certificate confirming the directors' share entitlement.
Worked borrowing examples — same person, three setups
Take a freelance designer earning £150,000 of business profit per year. Here's what they could borrow under each setup, at 4.5× standard mortgage multiple:
| Setup | Assessable income | 4.5× borrowing | With £80k deposit |
|---|---|---|---|
| Sole trader (£150k SA302 net profit) | £150,000 | £675,000 | £755,000 property |
| Ltd — standard route (£12k salary + £40k dividends drawn; £98k retained) | £52,000 | £234,000 | £314,000 property |
| Ltd — retained profits route (£12k salary + £138k share of net profit) | £150,000 | £675,000 | £755,000 property |
Same person, same business performance. The Ltd standard route under-borrows by £441,000 against the same person under sole trader or Ltd retained-profits routes. That's how huge the structural difference is.

Which structure gives more borrowing?
Pure mortgage perspective
- Sole trader generally wins for borrowing access. Most lenders, simplest paperwork.
- Ltd retained profits route ties or beats sole trader if you can find the right specialist lender.
- Ltd standard route loses if you're tax-efficient. Wins only if you're already drawing nearly all profit as salary+dividends.
But tax and mortgage trade off
The tax-efficiency reason for going Ltd is exactly the same setup that hurts you on the standard mortgage route: minimal salary, modest dividends, retain the rest. The fix is the retained-profits lender route — which means you need a broker who knows which lenders take it.
Don't restructure your business just to optimise mortgage borrowing — the tax cost of switching to sole trader or drawing all your profit as personal income usually outweighs the mortgage benefit. Instead: find the right lender for your existing structure.
Paperwork by structure
Sole trader paperwork
- SA302s for the last 2–3 years (from HMRC Government Gateway)
- Tax Year Overviews for the same years
- 3–6 months of business bank statements (or personal if you mix)
- 3–6 months of personal bank statements
- ID and proof of address
Ltd director paperwork (standard route)
- 2–3 years of filed company accounts (from Companies House)
- 2–3 years of personal SA302s + Tax Year Overviews
- 2–3 years of P60s and payslips for your director's salary
- Dividend vouchers / record showing dividends drawn
- 3–6 months of business bank statements
- 3–6 months of personal bank statements
- ID and proof of address
Ltd director paperwork (retained profits route)
Everything from the standard route, plus:
- Accountant's certificate confirming your directorship, share entitlement (e.g. 100% of shares), and your share of net company profit for the relevant periods. Lenders often have a template they want filled in.
- Sometimes the latest management accounts (in-year unaudited figures) demonstrating trade continuity.
Related decisions: what business structure should you actually use?
If you're not yet a Ltd and trying to decide, the mortgage angle is one of several inputs. Other major factors:
- Tax efficiency — Ltd typically saves tax at £40k+ profit. Use our limited company take-home calculator to see your specific position.
- Admin overhead — Ltd requires annual accounts, corporation tax return, payroll if you take salary. £80–150/month for an accountant typically covers it.
- Liability protection — Ltd separates business risk from personal liability. Relevant if you're in high-risk service categories.
- Client expectations — corporate clients sometimes prefer suppliers to be Ltd. Less common as a hard requirement than it used to be.
- IR35 considerations — for contractors. See our inside vs outside IR35 explainer.

Should I switch structure before applying for a mortgage?
Almost never a good idea purely for mortgage reasons. Reasons:
- Lender clock resets — many lenders want 2 years of accounts in your current structure. Switching means starting that clock again.
- Tax cost outweighs mortgage benefit — going from tax-efficient Ltd to "drawing all profit personally as Ltd salary+dividends" typically costs more in tax annually than the mortgage benefit is worth.
- Specialist lenders solve it without restructuring — the retained-profits route exists specifically so you don't have to.
The exception: if you're a brand-new Ltd (less than 6 months in) with strong previous sole trader history, applying as sole trader with your previous SA302s sometimes makes sense. Don't try to game it with switches in the 12 months before applying.

Yes — for mortgage assessment purposes the retained-profits route attributes the company's net profit to directors in proportion to share ownership. A sole director / sole shareholder gets 100%. For multi-director setups, the assessment is your equity share.
Risk appetite and underwriting cost. Retained profits is a more nuanced assessment — the lender has to verify the company can sustainably distribute that profit to you if needed. Most high-street lenders standardise on the simpler "what did they actually draw" approach. Specialist lenders accept the extra underwriting cost in exchange for serving a meaningful market.
You typically need 2 years of profitable accounts under your current structure. A Ltd that swung from loss-making to profitable last year would struggle on the standard 2-year route. Some specialist lenders accept 1 year if the trajectory is clearly positive and continuing trade evidence is strong.
You're in a "high salary+dividends" position. The standard route works for you — your assessable income is close to your full business profit. No need for the retained-profits specialist route in that case.
Not directly — the products are the same. Rates depend on the lender, LTV, fixed-rate term, and your specific profile. The "different rate" myth is usually because Ltd directors end up at specialist lenders (where rates are slightly higher) when the standard route under-borrows them. The fix is finding the right lender match for your case.
Partnerships (LLP or general partnership) are assessed similarly to sole traders — lenders use your share of partnership profit from your SA302. Multi-partner setups need an accountant's certificate confirming your share. Most lenders handle this fine; the paperwork is slightly more complex than pure sole trader.
Yes — joint applications combine both incomes. The Ltd director's income is assessed under whichever Ltd route works best (standard or retained); the salaried partner's income is the standard P60-based assessment. Lenders process both seamlessly in a joint application.
