Income evidence

Mortgage for contractors, CIS, zero-hours and probation

A solid day rate, regular CIS remittances, or a new job on probation can still leave a lender unsure what income to use. Structure, track record and documents usually matter more than the headline figure. This note is general information from Property Money Limited — not advice and not a personal recommendation.

The problem

Payslip language does not fit everyone. Contractors may be paid a day rate through a limited company, umbrella, or agency. CIS subcontractors often have tax deducted at source yet are still treated as self-employed for mortgage purposes. Zero-hours and variable-hours workers can show strong recent months and still fail affordability if the lender averages a quieter year. Probation periods raise a separate question: is the job secure enough for the income to count yet?

People often assume “I earn enough on paper.” Lenders ask a narrower question: which figure will we underwrite, for how long a history, and at what LTV?

What usually matters

• How you are engaged. Limited company contractor, umbrella, agency PAYE, sole trader CIS, and employed zero-hours are not interchangeable. The evidence pack follows the structure.
• Contractors on a day rate. Some lenders will annualise an acceptable day rate × contracted (or evidenced) days, often with a minimum contract length and a track record of similar work. Others ignore day-rate maths and want company accounts, salary and dividends, or an umbrella YTD figure instead. There is no single industry formula.
• CIS. Construction Industry Scheme income is generally treated as self-employed even when tax is deducted at source. SA302s, tax year overviews, CIS statements and bank credits usually travel together — not a classic employer reference.
• Zero-hours / variable hours. Lenders often want a longer average (for example 12–24 months of payslips or P60 history) rather than the best recent month. Gaps, seasonal dips and overtime that is not guaranteed can reduce the usable figure.
• Probation. Many high-street policies want probation completed, or a strong employer confirmation and time in role, before they will use the new salary in full. A brand-new role with a big uplift can mean waiting, a lower LTV specialist route, or using the previous income where criteria allow.
• Continuity. Rolling contracts, gaps between engagements, IR35 status changes, and moving from PAYE into a Ltd all change the story. Say what actually happened; the label “contractor” alone is too broad.

Paths that often help

• Match the pack to the structure. Day-rate contractors may need contracts, extensions, and a clear payment trail; CIS traders need tax calculations and CIS evidence; employed variable-hours workers need a run of payslips that show the pattern, not one peak month.
• Ask which income method applies before chasing a multiple. Day-rate annualisation, umbrella YTD, salary plus dividends, or net profit on SA302s produce different numbers on the same household.
• If probation is still open, expect either a wait until it ends, written confirmation the role is permanent, or a narrower product set — not a promise that every lender will ignore the probation clause.
• If hours bounce around, a longer clean average and realistic commitments often beat arguing for the highest month.
• Cross-check the self-employed guide where you trade through a sole trade, partnership or limited company — self-employed mortgage income covers SA302s and director income methods in more depth.

Mortgagability in plain terms

Mortgagability here means: will a lender accept this income definition for this engagement type, with enough history, at the LTV and term you need? A strong day rate does not automatically become a high-street salary multiple. CIS remittances do not make you PAYE employed. Zero-hours peaks do not always survive averaging. Probation can pause or shrink the figure until the role looks permanent. Our mortgage calculator only sketches payments — it does not underwrite contractor or CIS income.

Common mix-ups

Umbrella payslips can look like employment while the underwriting conversation still turns on contract history and continuity. Limited company contractors sometimes assume retained profit or a single large dividend will be treated like a salary; many lenders stay closer to what you have actually drawn, or to a share of net profit only where their criteria say so.

CIS tax deducted at source is not the same as PAYE employment for most mortgage policies. If someone has told you “they take tax off, so you are employed,” check that against how residential lenders actually classify CIS before you spend money on a valuation.

A new job with a better salary mid-probation is encouraging for you; it is not automatically usable income for every lender tomorrow. Waiting a few weeks for probation to clear can be cheaper than a decline and another hard search.

Variable overtime, tips, bonuses and shift premiums are often treated cautiously unless the history shows they are regular and likely to continue. Hope is not a payslip line.

While you weigh the mortgage, it is fair to ask whether the people who depend on the home would be unprotected if a contract ended. The protection gap analyser is an optional illustrative check only.
