TL;DR: You can typically get a mortgage on a zero-hour contract if you can demonstrate a consistent track record of earnings, usually over 12 to 24 months. Lenders will assess your average income to determine affordability, and having a larger deposit or a strong credit score can significantly improve your chances of approval.

Can I get a mortgage with a zero-hour contract?

The short answer is yes, it is possible to secure a mortgage while working on a zero-hour contract. However, the process is often more complex than it is for those in traditional salaried roles. Because zero-hour contracts do not guarantee a set number of hours or a fixed weekly income, many mainstream lenders view this type of employment as “non-standard” or higher risk.

Despite these challenges, the UK mortgage market has evolved. With more people working in the gig economy or in flexible roles within sectors like healthcare and hospitality, many lenders have updated their criteria. To succeed, you will likely need to provide more evidence of your financial stability than a typical employee would. This article explores how you can navigate the application process and what you need to do to prepare.

Why do lenders view zero-hour contracts differently?

When you apply for a mortgage, a lender’s primary concern is affordability. They want to be confident that you can meet your monthly repayments over the long term. If your income fluctuates from month to month, it can be harder for a lender to calculate exactly how much you can afford to borrow. A “bad month” with fewer hours worked could, in their view, put your mortgage payments at risk.

While this might seem unfair if you have worked 40 hours a week for several years, lenders look at the legal terms of your employment. Since your employer is not legally obligated to give you work, the lender sees a potential gap in your future income. To balance this risk, they will look for patterns of consistency in your past earnings.

How lenders calculate your income

Because you do not have a fixed salary, a lender cannot simply look at one payslip and multiply it by 12. Instead, they will usually look at your average earnings over a specific period. Most lenders will request your P60 documents and payslips from the last 12 to 24 months. They will then calculate an average weekly or monthly figure from this data.

Some lenders are more conservative than others. For example, some might take the lowest monthly amount you earned in the last year and use that as the basis for their calculation. Others may take a mean average but apply a “haircut” (a percentage reduction) to the total to account for potential future volatility. Understanding how different banks approach this calculation is why many borrowers choose to work with a specialist broker.

Requirements for zero-hour contract applicants

To qualify for a mortgage, you will generally need to meet several specific criteria that prove your reliability as a borrower. While every lender has its own rules, the following are common requirements:

• Consistent work history: Most lenders will require you to have been on a zero-hour contract for at least 12 months, often with the same employer. Some may accept 12 months in the same line of work even if you have changed employers.
• Industry relevance: Lenders often look more favourably on zero-hour workers in certain “high-demand” sectors, such as nursing, teaching, or social care. If your role is seen as essential, the risk of your hours being cut is perceived as lower.
• A healthy deposit: While 5% or 10% deposits exist, having a larger deposit (such as 15% or 20%) can make you a more attractive prospect. It reduces the lender’s overall risk and can open up a wider range of products.
• Strong credit history: Because your employment is seen as a risk factor, you want the rest of your financial profile to be as clean as possible. Consistent, on-time payments for utilities and credit cards are essential.

The importance of a track record

In the eyes of a mortgage provider, time is your best friend. If you have only been on a zero-hour contract for three months, it is highly unlikely a high-street bank will offer you a mortgage. They need to see that your income is sustainable across different seasons. For example, if you work in retail, your hours might spike in December but drop in January. A two-year history allows the lender to see how these peaks and troughs balance out over a full economic cycle.

If you are new to a zero-hour contract but have a long history in the same industry under a permanent contract, some specialist lenders may be more flexible. They might look at your overall career longevity rather than just the last few months of flexible working.

Improving your chances of approval

Preparation is key when applying for a mortgage with non-standard income. Here are several steps you can take to strengthen your application:

• Reduce existing debt: Lenders look at your debt-to-income ratio. If you have high credit card balances or personal loans, it reduces the amount you can borrow for a property. Try to pay down as much as possible before applying.
• Save for a larger deposit: A larger down payment lowers the Loan-to-Value (LTV) ratio. A lower LTV often leads to better interest rates and a higher likelihood of the lender overlooking the “risk” of your contract type.
• Organise your paperwork: Have at least two years of P60s, three to six months of payslips, and three months of bank statements ready. Any gaps in your employment should be explained clearly.
• Stay on the electoral roll: Ensure you are registered to vote at your current address, as this is a standard check used to verify your identity.

Understanding the risks of borrowing

While securing a mortgage is an exciting milestone, it is important to remember the responsibilities that come with it. When you have a fluctuating income, budgeting becomes even more critical. You must ensure that you can afford your mortgage payments even during months when your hours are lower than average. Failing to keep up with your mortgage can have serious consequences.

Your property may be at risk if repayments are not made. If you default on your mortgage, the lender may take legal action, which could ultimately lead to the repossession of your home. Additionally, missing payments will negatively impact your credit score, may result in increased interest rates on future borrowing, and could lead to additional charges and fees being added to your debt.

Should you use a mortgage broker?

For those on zero-hour contracts, using a mortgage broker is often highly recommended. Specialist brokers have access to the “intermediary” market—lenders who do not deal directly with the public and who often have more flexible criteria for non-standard income. A broker can help you identify which lenders are most likely to accept your specific contract type and help you present your income in the best possible light.

They can also save you from the disappointment and credit-score damage of a rejected application. Each time you apply for a mortgage and are turned down, it leaves a footprint on your credit file. A broker helps ensure you only apply to lenders whose criteria you actually meet.

People also asked

Can I get a 5% deposit mortgage on a zero-hour contract?

While 5% deposit schemes exist, they are harder to access with a zero-hour contract. You will likely need a very strong track record of consistent earnings and an excellent credit score to qualify for such a low-deposit mortgage.

How long do I need to be in my job before applying?

Most lenders require at least 12 months of continuous employment on a zero-hour contract, although some may require up to 24 months to prove income stability.

Do all lenders accept zero-hour contracts?

No, many high-street lenders have strict policies against zero-hour contracts. You may need to look at specialist lenders or smaller building societies that use manual underwriting to assess your individual circumstances.

Will a bank nurse on a zero-hour contract find it easier to get a mortgage?

Generally, yes. Lenders often view healthcare professionals on “bank” contracts more favourably because there is a perceived constant demand for their skills, making the income seem more secure than in other sectors.

Can I use overtime and bonuses to boost my application?

Yes, many lenders will consider overtime and bonuses, but they will typically only use a percentage of these extra earnings (often 50% to 100%) and will require proof that they are regular and sustainable.

Final thoughts on zero-hour contract mortgages

Applying for a mortgage with a zero-hour contract requires patience and thorough preparation. While you may face more scrutiny than a salaried employee, the rise of flexible working means that lenders are becoming more accommodating. By demonstrating a consistent work history, maintaining a clean credit record, and saving a solid deposit, you can position yourself as a reliable borrower.

Always take the time to compare different products and seek professional advice if you are unsure which path to take. With the right approach, being on a zero-hour contract does not have to be a barrier to owning your own home. Ensure you understand all the terms of your mortgage and have a financial “buffer” in place to manage the months when your work hours may be lower.
