How Do Childcare Costs Affect Your Mortgage Affordability?
- Jul 16
- 8 min read
See how much a nursery bill really costs your borrowing, and which lenders taper it as your child grows.
Quick Answer
Childcare costs reduce your mortgage borrowing, often more than any other outgoing. Lenders treat the monthly figure as committed expenditure, so a large nursery bill directly cuts what you can borrow. For working parents it is frequently the single biggest drag on affordability.
The figure they use is what you actually pay, not the headline cost. If free-hours entitlements or a government scheme reduce your bill, lenders work from the net amount that leaves your account.
The good news in 2026 is that the cost is temporary, and some lenders will recognise that. Where nursery fees end soon because your child starts school, a number of lenders will reduce or disregard the figure entirely.

Why childcare hits your mortgage harder than you expect
Most outgoings nibble at your borrowing. Childcare takes a bite. A full-time nursery place can cost more than a mortgage payment, and lenders subtract it before they work out what you can afford.
This produces the situation parents find hardest to accept: a household earning well can be offered less than a single applicant earning considerably less, purely because one of them has a nursery bill and the other does not.
It also explains why a second income sometimes adds less than expected. If most of that salary goes straight back out as childcare, the affordability gain is a fraction of the headline figure.
None of this is a judgement about parenting. It is arithmetic. Money committed every month is money that cannot service a mortgage, and childcare is simply the largest commitment many families have.
Two children under five is where it bites hardest. Families in that window often find affordability is the tightest it will ever be, at exactly the point they most want the space. It does ease, and knowing when it eases changes how you plan.
Case study: two salaries, one nursery bill
Here is an illustrative example. A couple we will call Hannah and Marc earn 38,000 and 34,000 pounds. On income alone they expected to borrow comfortably. Their two-year-old was in nursery four days a week at around 1,100 pounds a month.
That single figure was treated as committed expenditure and reduced their maximum borrowing by roughly the same as a large car finance agreement and a student loan combined. Their first lender came back well below what they had budgeted for, and they assumed something was wrong with their credit.
Nothing was. The answer was lender choice. Their child was due to start school within eighteen months, and a lender that reduced the childcare figure as the end date approached produced a materially different result on the same income and the same deposit. These figures are illustrative only and not a quote, but the gap between lenders on this single line is real and it is worth shopping for.
How lenders count childcare costs
Under the Financial Conduct Authority (FCA) Consumer Duty, in force since 2023, lenders must check that a mortgage is genuinely affordable. Childcare goes into the committed expenditure section of that assessment, and you will be asked for it directly.
They want the monthly figure you actually pay. That means after any free-hours entitlement and after any government scheme support, because the net number is what leaves your account.
What lenders ask | How they use it |
Your monthly childcare cost | Counted as a committed outgoing |
Who pays it | Split across joint applicants |
Whether it is term-time only | Some average it across twelve months |
Free hours or scheme support | They use your net cost, not the gross |
When the cost ends | Some reduce or disregard it |
Whether you use a government childcare scheme, and how it sits with your wider tax position, is a question for a qualified UK tax adviser rather than a mortgage matter. For the application itself, all a lender needs is the real monthly number, evidenced on your bank statements.
Joint applicants should give one consistent figure. Two people declaring different childcare numbers on the same application is a small thing that quietly undermines confidence in everything else, much like the overdraft habits a lender reads alongside it.
Will the cost be counted forever?
No, and this is where the right lender earns you real money. Childcare is one of the few large outgoings with a known end date, and lender policy on that varies more than almost anything else in affordability.
Some take today's figure and apply it for the whole mortgage term, which is the harshest reading. Others reduce it once free hours begin. A number will disregard it altogether where school starts within a defined window.
The practical move is to know your dates before you apply. If your child starts school in a year, that fact is worth pointing at, because it can change which lenders make sense for you.
This is one of the clearest cases in the cluster for using a wider panel of lenders rather than walking into your own bank. The income is the same, the deposit is the same, and the answer differs entirely because of how one line is treated.
Evidence helps here. A nursery invoice showing your notice period, or confirmation of a school place, turns "it ends soon" into a fact an underwriter can act on. Without it, a cautious lender will default to the harshest reading and apply today's figure indefinitely.
What goes in the box, and what does not
Applicants routinely over-declare here, which costs them borrowing they did not need to lose. Be accurate rather than cautious.
Counts: nursery fees, registered childminders, after-school and holiday clubs you pay for regularly, and any nanny or au pair costs.
Does not count: informal help from grandparents, occasional babysitting, and one-off holiday cover that is not a standing commitment.
Term-time-only costs deserve care. If you pay for thirty-nine weeks rather than fifty-two, say so. A lender that averages the figure across the year will land on a lower monthly number than one that takes your term-time bill at face value.
Be honest, though. Understating childcare to boost affordability is a poor plan, because the payments are visible on your statements and an underwriter who spots the mismatch will question everything else too. The same principle applies to every outgoing, as our guide on what lenders look for on your statements and account habits explains.
If affordability is still short once childcare is declared honestly, the useful levers sit elsewhere: clearing a car finance agreement, reducing unused credit limits, or improving the deposit. Our notes on improving affordability as a first-time buyer set out which of those actually moves the number.
Pros and cons of cutting hours before you apply
Some parents consider dropping a nursery day to improve affordability. It works, but it is not free, and it is worth seeing both sides before you rearrange your family around a mortgage calculator.
The case for. Removing a day of childcare lifts your borrowing straight away, and the effect is larger than most people expect given how big the outgoing is.
The case for. It can also be genuine. If a parent is moving to a four-day week anyway, the reduced cost reflects reality and there is nothing artificial about it.
The case against. Fewer childcare days usually means fewer working hours, and lower income can cancel out the gain entirely. The two move together.
The case against. It is temporary if you plan to reverse it. Cutting hours to pass affordability and restoring them after completion leaves you with a mortgage sized for a household that no longer exists.
The case against. Lenders may ask. A childcare figure that drops sharply in the month you apply invites a question about whether it is sustainable.
The better route is usually lender selection rather than lifestyle surgery. The Money and Pensions Service offers free budgeting support if the numbers are genuinely tight, and the Bank of England's lending standards mean affordability has to be realistic in any case. UK Finance members apply their own childcare policies, so the same family can get very different answers without changing a thing.
FAQs
How much do childcare costs reduce my mortgage?
Substantially, because the monthly figure is treated as committed expenditure. A large nursery bill can reduce borrowing by a similar amount to a car finance agreement and a student loan combined, though every lender's calculator differs.
Do lenders use my childcare cost before or after free hours?
After. They want the net figure that actually leaves your account each month, so any entitlement or scheme support that lowers your bill also lowers the number used in the assessment.
Will a lender ignore childcare if my child starts school soon?
Some will, and this is where lenders differ most. Policies range from applying today's figure for the whole term to disregarding it where school starts within a set window, so the end date is worth raising early.
Do I need to declare childcare if grandparents help for free?
No. Only regular costs you actually pay are committed expenditure. Informal, unpaid family help is not a commitment and should not appear in the figure you give a lender.
What if I only pay during term time?
Say so clearly. Many lenders will average a term-time bill across the year, which produces a lower monthly figure than treating your term-time payment as if you paid it every month.
Summary
Childcare costs cut mortgage affordability harder than almost any other outgoing, because lenders count the monthly figure as committed expenditure. They use what you actually pay after free hours and scheme support, not the headline fee. In 2026 the biggest opportunity is lender choice: policies on tapering fees that end when a child starts school vary widely, and the same family can receive very different offers as a result.
