Maternity Leave Mortgage: Buying or Remortgaging While on Parental Leave

By Jake Stott, Knox Mortgages. Reviewed by an adviser authorised under Fort Advice Bureau, FCA FRN 972730. Published 25 September 2026. Last reviewed 25 September 2026.

A maternity leave mortgage is a normal residential mortgage or remortgage taken out while one applicant is on maternity, paternity, shared parental or adoption leave. There is no special product. Most mainstream lenders will assess you on the salary you return to, not your maternity pay, provided your employer confirms your return date and pay. What changes the outcome is which lender you use, whether you go back full-time or part-time, and how childcare is counted.

So yes, you can get a mortgage on maternity leave, and you can remortgage on maternity leave. Being pregnant or on leave is not a reason for a lender to decline you, and pregnancy and maternity are protected characteristics under the Equality Act 2010. But lenders are required to check that the mortgage is affordable through the period of reduced pay and after it, and they each do that differently. Pick the wrong one and a case that should have been straightforward gets cut down or declined.

This guide sets out how eight major lenders assess income on parental leave as of September 2026, taken from their own intermediary criteria, with the arithmetic shown.

Can I get a mortgage on maternity leave?

Yes. Every major UK lender will consider an application from someone on maternity leave, and most will lend on your full return-to-work salary rather than statutory maternity pay. The condition is evidence: a payslip from before your leave showing your normal salary, and usually a letter from your employer confirming your return date and the salary and hours you are coming back on.

Where lenders differ is in the detail. Some will use your pre-leave salary with nothing more than your confirmation that you are returning on the same terms. Others want an employer letter in every case. A few will write to your employer themselves. Some test whether you can cover the mortgage during the months you are on reduced pay, and ask about savings if the answer is no.

The cases that go wrong are rarely about the leave itself. They are about returning part-time without telling the lender, leaving out childcare costs, relying on bonus or overtime after a long break, or choosing a lender whose rules do not fit your situation. A broker’s job here is to match the case to the lender before anything is submitted, so the underwriter sees exactly what they expect.

How do lenders assess income on maternity leave?

Lenders use one of three approaches, and knowing which one your lender uses tells you roughly what you can borrow.

On top of the income figure, most lenders run a second test: can you afford the payments during the leave itself? For most people that means showing the reduced income plus savings covers the gap. Santander asks for the lowest income you expect during parental leave and, if that is not enough, evidence of other funds such as savings. Halifax tells advisers they must be satisfied the customer can maintain repayments throughout any period of reduced income, naming maternity and paternity leave as examples.

The practical point: a lender using your full salary is not ignoring your leave. It is lending on the long-term picture and checking you have a plan for the short-term dip.

Which lenders use my full salary on maternity leave? Eight lenders compared

This table is taken from each lender’s published intermediary criteria, checked on 25 September 2026. Criteria change often, so a broker should confirm the current position before you apply.

Sources: Nationwide for Intermediaries (other income), Halifax Intermediaries (criteria), Barclays Intermediaries (residential income and commitments), NatWest Intermediary Solutions (income and packaging, lending criteria), Santander for Intermediaries (residential evidence requirements guide, August 2026), HSBC for Intermediaries (FAQs), Coventry for Intermediaries (residential criteria), Skipton Intermediaries (A to Z residential criteria). Retail pages from Co-operative Bank confirm a similar stance: it can base lending on the salary you will return on, confirmed by your employer.

What should the return-to-work letter from my employer say?

The letter should confirm four things: your return date, your annual basic salary on return, your contracted hours on return, and that your role continues. If you are changing hours, it should state the new hours, the new salary and the date the change takes effect, because NatWest and Barclays both ask for that detail specifically.

Get it on company letterhead, signed by HR or your line manager, and addressed to you personally. Nationwide says employer letters must include your address and confirm your return income; a generic “to whom it may concern” letter can be rejected. Date it recently. A letter written a year ago, before you had decided on part-time hours, does not help.

Two common problems. First, employers who will not commit to a return date because you have not formally confirmed it. The fix is to give HR the date you intend to return and ask them to confirm it. Second, letters that say “salary to be confirmed”. If your employer is mid pay review, ask them to state your current contractual salary instead. An underwriter can only use a figure that is written down.

Does childcare affect how much I can borrow?

Yes, and it is one of the biggest reasons figures change between the first quote and the mortgage offer. Lenders deduct childcare as a monthly commitment, in the same way as a car loan, before working out what is left to support the mortgage. Nationwide requires both existing and future childcare costs to be included for applicants on or about to go on parental leave. Santander asks you to explain alternative arrangements if you declare no childcare.

NatWest goes further than most. Its criteria say childcare costs should be considered over the next 5 years and the highest cost used, and you can declare your expected cost or use national averages if you have not booked a place yet. NatWest also lists situations where childcare should not be included, such as free care from a relative or funded free hours.

That last point matters. In England, eligible working parents can get up to 30 hours of funded childcare a week (term time) for children from 9 months old. If your return-to-work plan relies on funded hours plus a grandparent, say so, with the numbers. A lender deducting a full-price nursery place you will never pay for can cut tens of thousands off your maximum loan for no reason.

What if I am going back to work part-time?

Then the lender will use your part-time salary, not your old full-time one. This is the single most common place applications fall over, because people apply on their old salary and mention the change later.

NatWest and HSBC calculate your future salary pro rata from your previous basic pay: go back three days a week on a £40,000 full-time salary and they will use £24,000. Barclays needs confirmation that your employer has approved the change in hours. Coventry asks for an employer’s reference. Santander needs an employer letter whenever your working pattern changes.

If you have not decided yet, be honest about it. It is better to apply on the lower figure and have headroom than to apply on full-time pay and then need to tell the lender you are going back at 0.6. A change like that after an offer is issued can mean the offer is withdrawn and the whole case re-underwritten. If the part-time figure does not reach the loan you need, the options are a larger deposit, a longer term, a lender with a higher income multiple, or waiting until your new pattern is settled and your part-time payslips show it.

Worked example: how the lender’s choice changes what you can borrow

Here is an illustrative purchase, with the arithmetic shown. Sarah and Tom are buying at £340,000 with a £34,000 deposit (10%), so they need £306,000.

• Sarah: £38,000 basic salary, currently on maternity leave receiving statutory pay.
• Tom: £45,000 basic salary.
• Assume a lender lending up to 4.5 times income, which is typical.

Scenario B is why lender choice matters. The same couple, same house, is either approved with room to spare or £58,000 short depending on whether the lender counts Sarah’s real salary.

Scenario C is the honest one if Sarah is going back part-time. It misses by £900, which is fixed by adding £900 to the deposit or by using a lender with a higher multiple (Scenario D).

Now the affordability check. Lenders stress test payments at a higher rate than the one you will pay. At an illustrative stress rate of 7% over 30 years, £306,000 costs about £2,036 a month (roughly £665 per £100,000 borrowed). Using 2026/27 tax and National Insurance, Tom’s take-home is about £2,993 a month and Sarah’s part-time take-home about £1,661, so £4,654 together. Nursery for 3 days at £75 a day is about £975 a month (£75 x 3 x 52 / 12).

£4,654 minus £2,036 minus £975 leaves £1,643 a month for everything else: bills, food, travel, credit commitments. Some lenders’ models will accept that comfortably; others, using higher spending assumptions for a family with a baby, will cut the loan. That is the gap a broker is checking before anything is submitted.

These figures are illustrative and not an offer of credit. Your own figures depend on the lender, your credit commitments and your full circumstances.

Can I remortgage while on maternity leave?

Yes. Remortgaging on maternity leave to a new lender is assessed exactly like a purchase: the new lender underwrites your income, uses your return-to-work salary if its criteria allow, and deducts childcare. Everything in the lender table above applies.

Timing matters more than people expect. If your fixed rate ends during your leave, you do not want to roll onto the lender’s standard variable rate, which is usually far higher than any fixed deal. You can typically secure a new rate up to about 6 months before your current deal ends, so if your fix ends 3 months after the baby is due, the sensible move is to start the process while you are still on full pay.

If you want to raise extra money, for an extension to fit a growing family for example, you will need a full remortgage with affordability checks. That is where the return-to-work letter, a clean bank statement and a realistic childcare figure do the heavy lifting. If you only need to change your rate and keep the same loan, a product transfer is usually the simpler route. Our remortgage page explains the full process and timescales.

Product transfer or remortgage on maternity leave: which is easier?

A product transfer is usually easier on maternity leave. A product transfer means moving to a new rate with your existing lender on the same loan amount. Because you are not borrowing more, FCA rules allow the lender to skip a full affordability assessment for a like-for-like switch, so your maternity pay and childcare costs generally do not come into it.

A remortgage to a new lender can get you a better rate, release equity or change the term, but it means full underwriting while you are on reduced pay. For many families on leave the right answer is to take the product transfer now, then review a remortgage when you are back at work and your new salary shows on payslips.

We compare the two in detail on our product transfer vs remortgage guide. The key point for parents on leave: the product transfer is the safety net. It stops you drifting onto the variable rate while the new salary picture settles.

Should I apply before I go on maternity leave?

Often, yes. Applying before your leave starts means your latest payslips show your normal salary, which is the simplest possible evidence. But you must still answer the application honestly. Lenders ask whether you expect any change in your income or spending, and a planned maternity leave is a foreseeable change.

Not disclosing it is not a strategy. If a lender later finds you knew about an upcoming change and did not declare it, it can withdraw the offer, and in the worst cases treat it as misrepresentation. Telling the lender does not usually hurt you, because most of them will use your return-to-work salary anyway.

Watch the dates. Mortgage offers are typically valid for around 3 to 6 months, depending on the lender. If you are buying a new build or the chain is long, your leave may start before completion. Some lenders re-check income before releasing funds, so the case needs to hold up on either basis. First-time buyers should read our first-time buyer guide for the full timeline from offer to completion.

Can I get a mortgage on paternity, shared parental or adoption leave?

Yes. Most lenders group maternity, paternity, shared parental and adoption leave together under “parental leave” and assess them in the same way. Nationwide, Santander, Skipton and Coventry all use the term parental leave in their criteria, and NatWest covers maternity and paternity leave in the same entry.

Paternity leave is usually short, 1 or 2 weeks, so it rarely affects an application at all beyond a single lower payslip. Explain it and move on. Shared Parental Leave is different, because you and your partner can share up to 50 weeks of leave and up to 37 weeks of pay between you. If both of you are on reduced pay at the same time, both incomes need return-to-work evidence, and the lender’s “lowest income during leave” test becomes much harder to pass without savings.

Statutory pay for all of these is £194.32 a week (or 90% of average earnings if lower) for 2026/27, per gov.uk. Adoption leave follows the same structure as maternity leave. The evidence is the same: pre-leave payslips, and an employer letter confirming return date, salary and hours.

Can I get a mortgage if I am self-employed and on Maternity Allowance?

Yes, but the approach is different because there is no employer letter. Self-employed parents do not get Statutory Maternity Pay. Most get Maternity Allowance instead, which is between £27 and £194.32 a week for up to 39 weeks in 2026/27, depending on National Insurance contributions. Most lenders will not treat Maternity Allowance as income for the mortgage. They assess you on your trading figures, as with any self-employed mortgage.

The problem arrives later. Lenders usually average your last two years of net profit, or use the lower of the two. A year where you took six months off drags that average down. Nationwide says self-employed applicants on parental leave follow its standard self-employed criteria, so there is no special allowance for the dip.

Three ways around it:

• Apply before the reduced year shows up in your tax returns, using the two full years you already have.
• Use a lender that will look at your latest year alone where it is the higher figure.
• If you run a limited company, choose a lender that will assess retained profit as well as salary and dividends, which can smooth over a year where you drew less.

Getting the timing right here can be worth more than the rate. Talk to a broker before you file the tax return that covers your leave.

What gets a maternity leave mortgage declined, and how to fix it

Most declines on maternity leave cases are avoidable. These are the ones we see most often, with the fix for each.

The pattern is the same in almost every case: the underwriter found something the application did not say. Put everything on the table at the start and match it to the right lender, and maternity leave becomes a paperwork question rather than a lending one.

Illustrative Knox case: remortgage with 4 months of leave left

This is an anonymised, illustrative case based on the type of enquiry Knox handles. A couple in Greater Manchester had a 5-year fix ending while one of them, a nurse, was 8 months into maternity leave. She planned to return at 30 hours instead of 37.5. They wanted to release £25,000 for a loft conversion.

Their existing lender offered a product transfer on the current balance, but a further advance for the extra £25,000 meant full affordability on her maternity pay, which did not work.

We took a different route. Her employer confirmed the return date and her pro rata salary in writing. We declared nursery costs for 3 days a week, net of the funded hours they would qualify for. Then we placed the case with a lender that uses confirmed return-to-work income and pro rata salary, with enough headroom on the combined incomes to include the £25,000.

The result was a new 5-year fix including the additional borrowing, completed before the old deal expired, with no months on the standard variable rate. The case turned on two documents, the employer letter and an honest childcare figure, and one decision: which lender.

How Knox handles maternity leave mortgages

We start with your numbers, not a product. On a free discovery call we work out which income figure each lender would use for you, what childcare will do to affordability, and whether a product transfer, remortgage or purchase makes sense now or after you return. If you are unsure what you can borrow at all, our how much can I borrow guide explains how lenders calculate it.

Then we package the case so the underwriter sees exactly what their criteria ask for: the right payslips, the right wording in the employer letter, and a childcare figure you can defend. Knox is whole-of-market, so we are not tied to one bank’s rules. That matters here more than almost anywhere, because the gap between lenders on parental leave is so wide.

Whether you are a first-time buyer, moving home to make room for a growing family, or remortgaging with a fix ending mid leave, book a call before you apply anywhere. It is far easier to choose the right lender first than to fix a decline afterwards.

Frequently asked questions

Can I get a mortgage while on maternity leave?

Yes. Most mainstream lenders will lend while you are on maternity leave and assess you on your return-to-work salary, not your maternity pay. You will usually need a payslip from before your leave and a letter from your employer confirming your return date, salary and hours. Lenders also check you can cover the payments during the leave itself.

Does maternity leave affect a mortgage application?

It affects the evidence and the affordability check, not your eligibility. Lenders want to know what you will earn when you return, how childcare will affect your spending, and how you will cover the payments while on reduced pay. Returning part-time reduces the income used. Handled properly, maternity leave does not stop an application.

Will lenders use my full salary or my maternity pay?

Most use your full salary if you are returning on the same terms. Nationwide, Barclays, NatWest, Santander, HSBC, Coventry and Skipton all base lending on return-to-work income, with conditions. Halifax accepts maternity pay keyed as basic income where you return on the same terms, but not Statutory Maternity Pay on its own.

Can I remortgage while on maternity leave?

Yes. A product transfer with your current lender is usually simplest, because a like-for-like rate switch generally needs no affordability check. A remortgage to a new lender, or borrowing more, is fully underwritten on your return-to-work income and childcare costs. Start 6 months before your fixed rate ends to avoid the standard variable rate.

Do I have to tell my mortgage lender I am pregnant?

You must answer the application honestly. Lenders ask about foreseeable changes to your income or spending, and planned maternity leave is one. Not disclosing it risks the offer being withdrawn. Lenders cannot decline you because you are pregnant, and most will use your return-to-work salary anyway.

What if I am going back to work part-time?

The lender will use your part-time salary. NatWest and HSBC calculate it pro rata from your old basic pay; Barclays, Coventry and Santander want your employer to confirm the new hours and salary. Apply on the part-time figure from the start, because changing it after an offer can mean re-underwriting or withdrawal.

How does childcare affect how much I can borrow?

Childcare is deducted as a monthly commitment before the lender works out what you can afford, so it directly reduces your maximum loan. NatWest considers childcare over the next 5 years and uses the highest cost. Declaring funded hours and family care accurately can make a significant difference to the figure.

Can I get a mortgage on paternity or shared parental leave?

Yes. Most lenders treat paternity, shared parental and adoption leave in the same way as maternity leave, under their parental leave criteria. Paternity leave is usually too short to matter. Shared Parental Leave where both partners are on reduced pay at once needs return-to-work evidence for both, and often proof of savings.
