Contractor mortgages: how lenders assess day-rate workers
Last updated:
The contractor-mortgage market matured: a whole broker niche now underwrites on contractual day rate × hours × weeks, not drawings or net profit. That matters for LTD contractors who minimise salary (the tax-efficient default) — old-style affordability checks punished exactly that structure.
What lenders actually ask for
- Current contract + most recent invoice(s);
- CV showing 2+ years in the field (some lenders: 12 months minimum);
- Bank statements — the reality check on stated earnings;
- For umbrella workers: payslips, standard employed affordability.
Rates and the "specialist premium"
The old "contractors pay 2–3% over base" line is years out of date: high-street lenders now run day-rate policies at standard rates. The broker's value is knowing which ones — and that should cost you nothing (they take lender commission). Verify any "specialist fee" request against it.
Affordability maths runs off gross contract income, but your actual usable income is your take-home — see the calculator and the 2026/27 tables before deciding how much to borrow.
Day-rate underwriting maths, worked
A typical day-rate policy: (day rate × 5) × 46–48 weeks = annual contract income; some lenders apply ×48, some ×46, one or two ×52 with conditions. At £500/day that's roughly £115k–£120k of assessable income — against which mainstream lenders apply their standard multiples. The calculator shows what that rate actually nets, which is what the repayments come out of.
The two-year history question
Day-rate policies want 2+ years contracting (some 12 months with prior perm experience in field). Fresh contractors: 6–12 months of statements plus contract renewals can work with the flexible lenders; a broker shortlists which. Renewal evidence matters more than duration — unbroken renewals tell the underwriter the next 12 months look like the last.
Deposit sources and proof
Contractors' deposits often arrive as lumpier savings (retained dividend pots). Lenders want the paper trail: gift letters for family money, and statements showing accumulation rather than a recent mystery transfer. Start moving the deposit into one account 3+ months before applying.
Renewals, gaps and the underwriter's story
Underwriters don't lend against a rate; they lend against a pattern. The file that works: current contract, last renewal, and a CV showing unbroken field history. The file that fails: one 6-month contract after a career break with no renewal. If you're six months from applying, engineer the pattern first — renew the current contract, bridge short gaps with the next engagement signed before the mortgage application, not after.
Umbrella vs LTD from the lender's chair
Umbrella workers are underwritten as employed (payslips + P60) — simpler, slightly smaller assessable income. LTD contractors get the day-rate multiple but supply more paper. Neither route is "better" for borrowing; the surprise for many is that the calculator's lower LTD net still supports a larger mortgage than their old perm salary did.
