Which UK lenders accept zero-hours contract income?

Zero-hours contracts are one of the most common reasons a perfectly affordable case gets stuck. The income is real, often substantial, and frequently long-standing — but because the contract guarantees nothing on paper, lenders treat it with caution and every one of them treats it slightly differently.

The short answer: yes, plenty of mainstream UK lenders accept zero-hours contract income — including high-street names — provided the case is packaged the way each lender wants to see it. The work is in knowing which lender will take your client, with their length of service, in their sector.

This guide covers how lenders assess zero-hours income, what you need to evidence, and the fastest way to find the lenders that will say yes.

How lenders actually assess zero-hours income

There's no single rule. But almost every lender's policy turns on the same handful of questions:

• How long has the client been in the role? This is the big one. Many lenders want to see a minimum period in the same job or sector — often 12 months, sometimes less for certain professions, occasionally more.
• Is the income consistent? Lenders look at payslips and bank statements to judge whether the hours are stable or erratic. A nurse picking up regular bank shifts reads very differently from someone with sporadic, seasonal work.
• How do they average it? Most lenders take an average of the last 12 months, but some use the lower of the last 12 months versus a year-to-date figure, and a few will consider a shorter window. The averaging method can swing the usable income by thousands.
• What's the sector? Some lenders are noticeably more comfortable with zero-hours income in healthcare, education, and the public sector than in, say, hospitality or retail.
• Is it the sole income or a top-up? A zero-hours role alongside a permanent salaried job is treated very differently from a client whose entire income is zero-hours.

What you'll need to evidence

To give the case the best chance, gather:

• Payslips — usually 3 months minimum, often 12 months to demonstrate the pattern.
• Bank statements — typically 3 months, to corroborate the payslips and show the income landing consistently.
• An employer reference or contract — to confirm length of service and that the arrangement is ongoing.
• A clear income summary — annualised correctly. This is where a lot of cases fall down: overtime, enhancements, and shift premiums on top of zero-hours base pay have to be averaged and presented properly, or the underwriter does it conservatively for you.

The packaging mistake that loses these cases

The most common reason a viable zero-hours case gets declined isn't the contract type — it's a weak or inconsistent income figure. If the payslips show variable pay and the application states a single optimistic number, the underwriter trusts the documents, not the form. They'll average it down, the affordability drops, and the case fails.

The fix is to annualise the income exactly the way the lender will: average the right period, treat each pay element correctly, and submit a figure you can evidence to the penny. Done properly, a zero-hours case is often far stronger than it first looks.

How to find the right lender, fast

Because every lender's stance on length of service, averaging, and sector is different — and because these policies change — the reliable way to place a zero-hours case is to check current lender criteria directly rather than working from memory or a months-old crib sheet.

That's exactly what MortgageBrokerHub's lender criteria search is built for. Ask a plain-English question — "which lenders accept zero-hours contract income with 9 months in the role?" — and get a structured comparison across 100+ UK lenders, each answer backed by the lender's own policy wording. No digging through PDFs, no guesswork.

And once you've found the lender, MortgageBrokerHub's payslip analysis annualises the zero-hours income for you — overtime, enhancements and all — and produces a lender-ready evidence pack, so the figure you submit is the figure that holds up.

Frequently asked questions

Can you get a mortgage on a zero-hours contract? Yes. Many mainstream lenders accept zero-hours income, particularly where there's a consistent track record and a reasonable length of service.

How much deposit do you need on a zero-hours contract? The contract type itself doesn't usually dictate the deposit — standard LTV bands apply. The key constraint is provable, averaged income, not a bigger deposit.

Do all lenders treat zero-hours income the same? No — length-of-service requirements, averaging methods, and sector appetite vary significantly between lenders, which is why checking live criteria per case matters.
