Mortgages for first-time buyers on zero-hours contracts

First-time buyer mortgages on zero-hours contracts

Zero-hours contracts can offer flexibility, but they can also make a mortgage application feel more complicated—especially when you’re buying your first home and you don’t yet have a track record with larger borrowing.

The good news is that a zero-hours contract doesn’t automatically rule you out. Lenders mainly want to understand whether your income is likely to support the mortgage repayments over the long term.

This guide explains how zero-hours income is commonly assessed and what you can prepare so your application is clear, consistent and easier to evaluate.

How lenders view zero-hours contract income

With a zero-hours contract, your pay can vary from month to month because the employer isn’t guaranteeing a minimum number of hours.

Because of that, lenders typically look beyond the headline “contract type” and focus on evidence of affordability, such as:

• Your recent earnings pattern (for example, whether income is broadly stable over time)
• How predictable your income appears based on what has happened historically
• Whether you have other reliable income (where applicable)
• Your overall financial commitments and how much “headroom” you have each month

In practice, many lenders will consider average earnings over a period rather than assuming your income will always be at its highest.

What matters most for affordability

Even if you have a strong deposit, lenders still need to be comfortable that repayments are affordable.

For first-time buyers on zero-hours contracts, affordability is usually influenced by:

• Monthly outgoings (credit commitments, childcare costs, existing loans, credit cards, etc.)
• The mortgage term you’re applying for (longer terms can reduce monthly payments, but increase total interest)
• The interest rate environment at the time of application (repayments can change depending on the product)
• Your ability to maintain payments during lower-income periods

A key point is that lenders want to see that you can cope not just with “good months”, but with the reality that earnings may fluctuate.

The documents that help your application make sense

Because zero-hours income can be harder to interpret, the quality of your paperwork can carry extra weight.

While each lender has its own process, applications are often strengthened when you can provide evidence such as:

• Payslips covering recent periods
• Bank statements showing regular income payments
• A clear employment history (including how long you’ve been with the employer)
• Details of any additional income (if relevant and evidenced)
• A breakdown of monthly expenditure so affordability is transparent

If your income has been variable, presenting the information clearly can help the lender understand the pattern rather than focusing on one unusual month.

Employment stability: what lenders look for

Zero-hours contracts vary widely. Some people work the same number of hours consistently, while others experience more dramatic changes.

Lenders commonly consider factors like:

• How long you’ve been in the role and whether the employment is ongoing
• Whether the work pattern looks steady (for example, regular shifts or recurring work)
• Whether there are signs of a change in circumstances that could affect future earnings

If you’ve recently started a new job or your hours have changed significantly, it doesn’t necessarily mean you can’t apply—but it may affect how lenders assess the income they can rely on.

Credit history and first-time buyer considerations

As a first-time buyer, you may have limited credit history. That can be fine, but lenders still assess how you manage money.

What can help include:

• Keeping existing accounts up to date
• Avoiding new credit applications close to the mortgage application process
• Ensuring your credit file is accurate

If you have any past issues (such as missed payments), it’s especially important that the application is presented in a way that addresses affordability and reliability clearly.

Mortgage types that may suit different circumstances

There isn’t one “zero-hours mortgage” product category that fits everyone, but the mortgage structure can matter.

Depending on your situation, you may find that lenders are more comfortable with certain approaches, such as:

• Fixed-rate deals that provide repayment certainty for a period
• Longer terms that can reduce monthly payments (though total cost may increase)
• Products that consider complex or non-standard income

The most suitable option depends on your deposit, borrowing amount, and the way your income is evidenced.

Common reasons applications for zero-hours contracts get delayed

Zero-hours applications can sometimes stall when information is missing or doesn’t align.

Typical issues include:

• Payslips and bank statements that don’t match the income figures used
• Gaps in employment history or unclear dates
• Outgoings that are incomplete or underestimated
• Large changes in circumstances not explained (for example, a new job or a shift in working pattern)

Being thorough at the start can reduce the chance of follow-up questions later.

How a mortgage broker can help with a zero-hours application

A broker’s role is to help match your circumstances to lenders and products that are more likely to understand your income profile.

For first-time buyers on zero-hours contracts, that often means:

• Interpreting how your income is likely to be assessed
• Helping you gather and present the right evidence
• Considering product structures that align with affordability
• Reducing the risk of submitting an application that doesn’t fit a lender’s typical approach

Preparing for the application process

If you’re planning to apply, a practical way to get ready is to:

1. Review your recent income evidence (payslips and bank statements)
2. List your monthly commitments accurately
3. Check your employment details are consistent across documents
4. Consider how you’d manage repayments in lower-income months

This preparation won’t guarantee an outcome, but it can make your application easier to assess and can help you avoid avoidable delays.

Important notes

• Mortgage lending decisions are made by individual lenders using their own criteria.
• Affordability assessments consider more than contract type; they focus on the evidence of income and your overall financial position.
