Employment Types: Mortgages for people on zero-hour contracts

If you’re employed on a zero-hours contract, it’s understandable to worry that a lender will see your income as unpredictable. In many cases, a residential mortgage may still be possible, but your application is usually assessed around how reliably your earnings can be evidenced over time.

This guide focuses on zero-hours contracts. For related situations, see:

With zero-hours contracts, lenders typically look for a clear picture of:

your employment continuity
your working pattern and earnings history
the proof of income you can provide

When your income varies, the “strength” of your application often comes down to how well your payslips and bank activity support a consistent, explainable trend.

Zero-hours contract mortgage guide

What is a zero-hours contract?

A zero-hours contract is an employment arrangement where your employer does not guarantee a minimum number of hours. Work is offered as and when it’s available.

For mortgage purposes, the key point is that your income may fluctuate. That doesn’t automatically prevent you from borrowing, but it often means lenders take a more cautious approach when deciding how much income they can use for affordability.

Can you get a mortgage on a zero-hours contract?

It may be possible, depending on the lender and your circumstances. While each lender has its own rules, zero-hours contract applications commonly come down to whether the lender is satisfied that:

your employment is genuine and ongoing
your earnings show a pattern they can reasonably assess
you can provide suitable documentation

Even where zero-hours income is accepted, lenders may use a more conservative approach than they would for a fixed-salary role.

What lenders usually check

Although criteria vary, most lenders focus on three themes.

Employment history and continuity

Lenders want confidence that your situation isn’t temporary. They may consider:

how long you’ve been working on zero hours
whether you’ve been in the same job or a similar role
whether your employment appears stable within your industry

In many cases, a longer and steadier employment history makes it easier to show that your income pattern is not just short-term.

Working patterns over time

Because hours can change, lenders often review your actual earnings and hours worked across recent months. They may look for whether:

your income has been broadly consistent
there are significant dips, gaps or sudden changes
your working pattern appears stable, improving, or declining

If your earnings have reduced over time, lenders may be less willing to rely on earlier higher figures.

Proof of income

You should expect to provide evidence that supports your income pattern. Common examples include:

recent payslips (covering the period the lender will assess)
tax year evidence where available (for example, a P60)
sometimes bank statements to support what’s shown on payslips
sometimes additional documentation if your income changed materially

The exact document pack can vary by lender and by how your earnings have behaved. If your earnings have changed over time, the lender may ask for additional documentation to understand the reasons and confirm the pattern going forward.

How lenders may calculate your income

Mortgage affordability is based on the income a lender is prepared to use. With zero-hours contracts, the figure used can differ between lenders.

In practice, lenders may use approaches such as:

taking an average of earnings over the period covered by your evidence
using a more recent set of payslips as a reference point
considering a longer-term history if it supports a stable pattern

Because these methods can produce different results, two applicants with similar gross earnings may be assessed differently depending on the lender’s underwriting approach and the strength of their documentation.

Deposit and LTV: why it can matter more

For many zero-hours contract applicants, deposit size can be particularly important. When income is variable, lenders may be more cautious about risk.

A larger deposit can help by:

reducing the overall loan amount
supporting a lower loan-to-value (LTV) position
improving the match with lenders that apply more conservative affordability assumptions

Changing the property value keeps the mortgage amount and recalculates your deposit or equity and LTV.

No mortgage borrowing needed

With these figures, the property value is fully covered by your deposit or equity. No mortgage borrowing is required.

Small mortgage amount

Fewer lenders offer mortgages below £25,000, so your options may be limited. Product and legal fees can also have a greater impact on the overall cost of a smaller mortgage.

Low property value

Fewer lenders offer mortgages on properties valued below £50,000. Minimum property values vary by lender and property type.

Buying to let?

If this is a buy-to-let purchase, most lenders cap borrowing at 75–80% loan-to-value, with some specialist options reaching 85%. This cap applies to buy-to-let mortgages only — residential lending typically extends to 95%.

High-LTV residential mortgage

Residential mortgages above 95% LTV have limited availability and often require a specialist mortgage product or scheme. Talk to your mortgage adviser about your options.

No deposit or equity buffer

You have no deposit or equity buffer. A fall in the property's value could leave you owing more than it is worth. No-deposit residential mortgages have limited availability and specific eligibility requirements. Speak to your mortgage adviser.

How much you may be able to borrow

Your borrowing potential depends on affordability, and affordability depends on the income figure a lender is willing to use.

With zero-hours contracts, the amount considered may reflect:

your recent earnings trend
how consistent your hours have been
the quality and completeness of your evidence
the lender’s approach to averaging or projecting income

As a result, the same household income can lead to different outcomes depending on underwriting method and the supporting paperwork.

If you have more than one income stream, the way each source is evidenced can matter as much as the headline amount. Lenders may also consider other income sources and how overall household affordability looks, particularly for joint applications.

Application timing and avoiding unnecessary delays

A zero-hours contract mortgage application can be smoother when your evidence is prepared early. Delays are more likely when documents are missing or when the application doesn’t clearly reflect your employment and earnings history.

A practical way to reduce friction is to ensure your application is consistent and well evidenced, for example:

having payslips available that cover the period the lender will assess
being ready to explain any gaps or significant changes in hours
ensuring employment details align across the application and documents
listing your monthly commitments accurately
considering 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 delays. Processing times vary by lender and depend on how quickly underwriting can verify the information provided.

First-time buyers on zero-hours contracts

First-time buyers can apply successfully on zero-hours contracts, but the same underwriting themes apply: lenders want confidence in affordability.

For first-time buyers, deposit planning can be especially important because purchase costs and deposit requirements affect the LTV you’re working towards. A clear document pack and an income profile lenders can understand and evidence can help reduce avoidable setbacks.

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.

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

Zero-hours contract mortgage considerations

Not automatically. Lenders don’t usually set different pricing purely because of the contract type. However, variable income can make lending decisions more selective, which may affect which products you’re offered.

Your deposit, credit history and the strength of your income evidence can all influence the options available.

Yes. Joint applications are assessed on combined affordability, but each applicant’s circumstances still matter. If the other applicant has more predictable income and a strong credit profile, it can help strengthen the overall application.

Interest-only options may be available depending on circumstances and lender criteria. Lenders typically look closely at how the mortgage will be repaid at the end of the term.

With interest-only, lenders often apply additional checks around affordability and the repayment plan.

Bad credit can make lending harder regardless of employment type. With variable income, lenders may be even more cautious, so addressing credit issues and improving the overall strength of your application can be particularly important.

Summary: what improves your chances

While every lender is different, zero-hours contract mortgage applications tend to go more smoothly when you can present an evidence-led picture of your income.

If your income varies, the goal isn’t to “fit” a standard profile. It’s to help the lender understand your earnings in a way that supports affordability.
