Mortgage While on Maternity or Paternity Leave

Applying for a mortgage during maternity or paternity leave adds a layer of complexity, but it absolutely does not make you unmortgageable. Lenders understand that parental leave is temporary, and most will assess you based on the salary you will return to — not what you are currently receiving.

How Lenders Assess Income During Parental Leave
The critical question is: what will you earn when you go back to work? Lenders are primarily interested in your long-term income, not the temporary reduction caused by statutory or contractual maternity/paternity pay.
Most mainstream lenders will:
- Use your pre-leave salary as the income figure for affordability
- Require written confirmation from your employer that you are returning, including your return date and salary
- Factor in childcare costs as an additional expense that reduces your disposable income
Some lenders may also want to see that your return date is within a reasonable period — typically within the next 3-6 months.
Get the employer letter right
The letter from your employer needs to confirm: your return-to-work date, the salary and hours you will return to, whether the position is the same or equivalent, and that your employment is ongoing. A vague letter will slow things down — be specific.
Statutory vs Enhanced Maternity/Paternity Pay
Your current pay during leave does not typically affect the income assessment, but lenders may look at it to understand your short-term affordability:
Statutory Maternity Pay (SMP): 90% of average weekly earnings for the first 6 weeks, then £184.03 per week (or 90% of earnings if lower) for the next 33 weeks.
Enhanced maternity pay: Many employers offer more generous packages — full salary for a period, then reduced pay. If you are on enhanced pay, your current income may be closer to your normal salary.
Paternity pay: Statutory Paternity Pay is £184.03 per week for up to 2 weeks. Shared Parental Pay follows similar rates to SMP.
Regardless of what you are currently receiving, the lender's primary focus is your confirmed return salary.
Childcare Costs and Affordability
Here is where it gets real. When you have a baby, lenders will factor childcare costs into your affordability assessment, even if you are not currently paying for childcare. They assume you will need it when you return to work.
This can significantly reduce the amount you can borrow. Typical childcare costs that lenders factor in:
- Full-time nursery: £800-1,400+ per month depending on location
- Childminder: £600-1,000+ per month
- After-school care for older children: £200-500 per month
If you can demonstrate that you will not have childcare costs (for example, a family member provides free childcare, or your partner is a stay-at-home parent), some lenders will accept this with appropriate evidence.
Existing children matter too
If you already have children, their childcare costs are factored into affordability as well. A second child adds significant costs that reduce your borrowing capacity. Be prepared to provide details of all childcare arrangements and costs.
Timing Your Application
You have several options for when to apply:
Before Going on Leave
Applying while you are still working and receiving your full salary is the simplest approach. You are employed, earning normally, and the lender assesses you on that basis. However, you must declare that you are pregnant or planning parental leave — failing to do so could constitute mortgage fraud.
During Leave (with a return date confirmed)
Most lenders will proceed if you have a confirmed return date and employer letter. The mortgage may complete before or after your return — either is usually fine.
After Returning to Work
This is the path of least resistance. You are back at work, receiving your normal salary, and can provide payslips to prove it. If timing allows, this is the simplest option.
During Shared Parental Leave
The same principles apply. Lenders want to know when you are returning and at what salary. Shared parental leave is less commonly encountered by underwriters, so having clear documentation is especially important.
Joint Applications
If you are applying jointly with a partner:
- Both on parental leave: Rarer but possible. Both need employer confirmation of return dates and salaries. Lenders will be more cautious.
- One on leave, one working: This is straightforward. The working partner's current income is assessed normally, and the partner on leave is assessed on their return-to-work salary.
- One staying home permanently: If one partner is not returning to work, only the working partner's income counts. Childcare costs may be reduced or eliminated in the affordability assessment.
What If You Are Not Returning to Work?
If you have decided to become a full-time parent, the mortgage assessment will be based solely on your partner's income (in a joint application) or you will need to demonstrate alternative income. Some options:
- Joint application based on partner's income alone
- Self-employment income if you are starting a business
- Rental income or investment income
- Benefits that the lender will accept
Be honest with the lender. Saying you are returning to work when you are not is misrepresentation on a mortgage application.
Practical Steps
- Get your employer letter confirming return date, salary, and hours as early as possible
- Calculate childcare costs realistically — lenders will ask
- Gather payslips from before leave — your last 3 payslips at full salary
- Check your credit file — parenthood does not affect it, but make sure everything else is in order
- Talk to a broker early — they can advise on timing and lender selection
- Be honest about your plans — returning, going part-time, or not returning at all
Going Back Part-Time
Many parents return to work on reduced hours. If you are going back part-time rather than full-time, the lender will use your part-time salary, not your previous full-time salary.
For example, if you earned £40,000 full-time and are returning three days a week, the lender will likely use £24,000 as your income. This can significantly reduce your borrowing capacity, so factor this into your plans early.
Discrimination Protections
Under the Equality Act 2010, it is unlawful for a lender to treat you less favourably because you are pregnant or on maternity leave. If you feel you have been discriminated against, you can complain to the lender, escalate to the Financial Ombudsman Service, or seek legal advice.
In practice, most lenders handle maternity and paternity leave applications routinely. It may take a little longer to process, and you may need to provide extra documentation, but it should not result in a fundamentally different outcome.
