If you’re on a zero-hours contract and wondering whether you can get a mortgage, you’re not alone — and the answer is yes, it is possible. What you need is the right lender, the right broker, and a clear understanding of how your income will be assessed.
High-street banks often treat zero-hours contract workers as too risky. Specialist lenders take a more nuanced view. This guide explains exactly what lenders look for, how to present your income in the strongest possible light, and what you can realistically expect to borrow.
What Is a Zero-Hours Contract Mortgage?
There is no specific “zero-hours contract mortgage” product — it is a standard residential mortgage applied to a borrower whose employment contract does not guarantee minimum hours. The challenge is purely one of income verification and lender appetite.
Zero-hours contracts (sometimes called casual contracts or variable-hours contracts) are common in hospitality, retail, healthcare, education, and the gig economy. The Office for National Statistics estimates that approximately 1 million UK workers are on zero-hours contracts at any given time. That is a substantial part of the workforce — and a segment many lenders are learning to serve.
How Lenders Assess Zero-Hours Contract Income
Income assessment is the central challenge for zero-hours contract mortgage applicants. Because your hours and earnings fluctuate, lenders cannot rely on a single payslip figure in the way they would for a permanent salaried employee.
What Most Mainstream Lenders Do
Many high-street lenders will either:
- Decline the application outright if they detect zero-hours contract employment
- Use only your guaranteed minimum hours pay for affordability — which for many ZHC workers is zero
This is why going direct to a mainstream bank is rarely the right approach for ZHC borrowers.
What Specialist Lenders Do
Specialist and building society lenders take a more practical approach. They typically look at:
- Average income over 12–24 months — using payslips and bank statements to calculate what you actually earn
- Consistency of earnings — steady or growing earnings over time are weighted positively
- Length of time with the same employer — longer tenure reduces perceived risk
- Nature of the work — some lenders distinguish between ZHC in stable industries (NHS, education) vs more volatile sectors
What Documents Do You Need?
Standard Documents
- 3–6 months payslips — showing actual hours worked and pay received each period
- 12–24 months P60s — annual tax year summaries from your employer confirming total earnings
- 3–6 months bank statements — verifying wages are being received consistently
- Employment contract — showing your zero-hours contract terms
- Proof of identity — valid passport or driving licence
- Proof of address — utility bill or council tax bill dated within 3 months
Strengthening Your Application
- 12 months of payslips where possible — the more data points, the more confident the lender
- Employer reference letter — confirming your role, tenure, and average hours/pay if available
- Evidence of regular shifts or bookings — some ZHC workers have effectively fixed patterns despite variable contract terms
How Much Can a Zero-Hours Contract Worker Borrow?
If a specialist lender uses your average annualised income from payslips, borrowing capacity is calculated at the same income multiples as employed applicants — typically 4 to 4.5× average annual income, with some lenders going to 5–5.5× for clean credit and strong income history.
| Average Annual Income | Standard (4×) | Enhanced (4.5×) | Specialist (5×) |
|---|---|---|---|
| £20,000 | £80,000 | £90,000 | £100,000 |
| £30,000 | £120,000 | £135,000 | £150,000 |
| £40,000 | £160,000 | £180,000 | £200,000 |
| £50,000 | £200,000 | £225,000 | £250,000 |
Illustrative figures only. Actual lending is subject to affordability assessment, credit history, LTV, income consistency, and individual lender criteria. Not a guarantee of borrowing amount.
How Long Do You Need to Have Been on a Zero-Hours Contract?
Most specialist lenders want to see at least 12 months of payslips from zero-hours contract employment with the same employer. Some lenders require 24 months. The longer your track record, the stronger your application.
What If You’ve Recently Started a ZHC Role?
If you have recently moved to a new employer on a zero-hours contract, most lenders will wait until you have at least 6–12 months of payslips from the new role. An exception applies if you can demonstrate a very long career history in the same sector — some lenders take a holistic view of income track record rather than focusing only on the current employer.
Deposit Requirements for Zero-Hours Contract Mortgages
A larger deposit improves your options significantly. Lenders who are willing to consider ZHC income are more likely to do so when the loan-to-value (LTV) ratio is lower.
- 10% deposit (90% LTV) — fewer lender options; requires strong income history and clean credit
- 15% deposit (85% LTV) — more lenders available; standard processing
- 25%+ deposit (75% LTV or below) — strongest position; more competitive rates; widest lender choice
If you can raise a 25% deposit through savings, a gifted deposit, or other means, your chances of approval on a zero-hours contract are substantially higher.
Adverse Credit and Zero-Hours Contract Mortgages
Having both a zero-hours contract and adverse credit history (missed payments, defaults, CCJs) significantly narrows your lender options. You’re likely looking at adverse specialist lenders with:
- Higher interest rates
- Minimum 15–25% deposit requirement
- Strict income verification over 24+ months
A specialist adverse credit broker is essential in this scenario to identify the lenders most likely to approve your specific combination of circumstances.
Industry-Specific Considerations
Healthcare and NHS Workers
Many NHS and social care workers are employed on zero-hours contracts. Some lenders recognise the stability of NHS employment and are more flexible about income averaging, particularly if bank statements show regular shifts from the same NHS trust or agency.
Education and Teaching
Supply teachers and hourly-paid lecturers often face the same challenges. Term-time earnings can look irregular on bank statements. A lender who understands education income patterns will annualise term-time earnings appropriately rather than penalising the summer income gap.
Hospitality and Retail
These sectors have the least predictable ZHC patterns and can be harder to evidence. Lenders will want to see the full 24-month payslip and bank statement history, and will likely require at least 15–20% deposit.
The Application Process for Zero-Hours Contract Workers
Step 1: Get a Specialist Broker
A whole-of-market broker who has placed ZHC applicants before is essential. They know which lenders will consider your income, how to present your payslips and bank statements, and how to anticipate and address underwriter questions before they arise.
Step 2: Get a Decision in Principle (DIP)
A DIP confirms indicative borrowing capacity before you commit to a property. Note: a DIP is not a mortgage offer — full underwriting happens later.
Step 3: Gather Your Documentation
Collect 12–24 months of payslips, matching P60s, and bank statements before applying. Having these ready in advance avoids delays once you’ve had an offer accepted.
Step 4: Full Application and Underwriting
The lender will review your income in detail. ZHC underwriting often takes longer than standard employed applications — expect additional questions about your employment history, hours pattern, and income consistency.
Step 5: Formal Mortgage Offer
If satisfied, the lender issues a formal offer (typically valid for 3–6 months). Your solicitor handles legal completion from here.
Common Reasons ZHC Mortgage Applications Are Declined
- Applying to the wrong lender — high-street banks that don’t accept ZHC income at all
- Insufficient payslip history — fewer than 12 months with the current employer
- Irregular or declining income — downward trend in hours or earnings raises red flags
- High LTV with ZHC income — some lenders cap at 85% LTV for ZHC applicants
- Multiple ZHC roles — some lenders will only consider the primary employer
Frequently Asked Questions
Can I get a mortgage on a zero-hours contract?
Yes — specialist lenders will consider zero-hours contract income using average earnings over 12–24 months. The key is finding the right lender, which typically requires a specialist broker. High-street banks are far less likely to accept zero-hours contract income.
How many months of payslips do I need?
Most lenders want a minimum of 12 months, with 24 months providing the strongest application. The full payslip history allows the lender to calculate your average annualised income reliably.
Does working for multiple employers on ZHCs affect my application?
It depends on the lender. Some will only use income from your primary ZHC employer. Others will aggregate ZHC income from multiple sources if supported by bank statements and payslips. A specialist broker will identify which lenders are most flexible for your specific situation.
What if my income has varied significantly from month to month?
High month-to-month variation is common with zero-hours contracts. Most lenders average income over 12–24 months, which smooths out seasonal peaks and troughs. Consistent year-on-year earnings or gradual growth over time is more important than monthly consistency.
Can I use overtime or bonus income from a ZHC role?
Some lenders will include consistent overtime or bonus income from zero-hours roles if it is evidenced over 12+ months of payslips and bank statements. Ad-hoc one-off payments are less likely to be included.
Will being on a zero-hours contract affect my mortgage rate?
Not directly — the rate is driven by your LTV, credit score, and the lender’s product range. The ZHC status affects which lenders will consider you, not necessarily the rate offered once you’re accepted. Clean credit and a 75–80% LTV can access competitive rates.
Can I get a buy-to-let mortgage on a zero-hours contract?
Yes — buy-to-let assessment focuses primarily on rental income coverage ratios (typically 125–145% of the mortgage payment). Lenders will still run background affordability checks on your personal income. ZHC background checks vary by lender; specialist broker advice is essential.
