Maternity Leave UK: Everything I Wish I'd Known (Honest Guide)

Updated May 2026. This guide covers UK maternity leave as it stands in 2026-27. Rates change in April each year so always double-check at gov.uk for current figures. This post is based on my own experience plus official guidance — it’s not legal advice, just a real-talk overview from one mum to another.

When I went on maternity leave back in 2020 I thought I’d done the research. I’d read the leaflets at the antenatal appointments. I’d skimmed gov.uk one evening. I’d talked to my HR person. I genuinely thought I had a handle on it.

I did not have a handle on it. There was so much I didn’t know, didn’t understand, or had completely misread. Some of it cost me money. Some of it cost me sleep. Some of it I only figured out after my son was already six months old and I should have done something months earlier.

So here’s the honest version — what UK maternity leave actually involves, in plain English, with the bits the official guides skip over included. If you’re pregnant and trying to work out what happens to your job and your money, start here.

Maternity Leave UK

How long can you take off in the UK?

UK statutory maternity leave is 52 weeks. That’s the longest paid (and unpaid) maternity leave entitlement in most developed countries, so if you’re moving here from elsewhere, this number can surprise you.

The 52 weeks are split into two parts:

Ordinary Maternity Leave — the first 26 weeks. Your job is fully protected. You return to your exact same role on the same terms.
Additional Maternity Leave — weeks 27 to 52. Your job is still protected, but slightly differently — you return to the same job or a similar job on the same terms if the same role isn’t reasonable.

You have to take a minimum of two weeks after the birth (four weeks if you work in a factory). After that, the rest is up to you.

You can start your maternity leave any time from 11 weeks before your due date. Most people start it a week or two before they’re due, but some start earlier (especially if the job is physically demanding or the commute is awful) and some work right up to the due date. I worked until 38 weeks and wished I’d stopped a week earlier — I was knackered and not really doing my best work.

Important: if you’re off sick in the four weeks before your due date for a pregnancy-related reason, your maternity leave may start automatically. Annoying but worth knowing.

How much will you actually get paid?

This is the bit everyone wants to know first and the bit that’s hardest to summarise in one sentence, because there are different routes depending on your situation.

The short version:

If you’re employed and meet the qualifying criteria, you get Statutory Maternity Pay (SMP) through your employer for 39 weeks.
If you’re self-employed or don’t qualify for SMP, you may be entitled to Maternity Allowance from the government for up to 39 weeks.
If you don’t qualify for either, you may be able to claim Universal Credit instead.

The full 52 weeks of leave is not all paid. The last 13 weeks are typically unpaid.

Below is the detail for each route.

Statutory Maternity Pay (SMP) explained

If you’re employed, this is most likely the one you’ll be on.

To qualify for SMP you need to:

Have been continuously employed by the same employer for at least 26 weeks by the end of your “qualifying week” (the 15th week before your due date)
Earn at least the Lower Earnings Limit (£129 per week for 2026-27)
Still be employed during the qualifying week
Give your employer at least 28 days’ notice that you want SMP

How much SMP pays:

First 6 weeks: 90% of your average weekly earnings, before tax
Following 33 weeks: the lower of either £194.32 per week OR 90% of your average weekly earnings (2026-27 rate)
Last 13 weeks (weeks 40-52): unpaid

The first six weeks at 90% is the bit most people don’t realise — it can be a meaningful amount of money if you earn well, and it’s only six weeks long. After that everyone drops down to the statutory flat rate (unless your employer tops it up, see below).

Your employer might pay more than statutory. Many do. Check your contract or HR policy. Mine had an enhanced maternity package on top of SMP — I would not have known to ask if a friend hadn’t told me to check. Ask. Always.

SMP is paid through your employer’s PAYE system, same as normal salary. Tax and National Insurance are deducted as normal.

Maternity Allowance (if SMP isn’t an option)

Maternity Allowance is the route for people who don’t qualify for SMP — most commonly:

Self-employed people
People who’ve changed jobs recently and don’t meet the 26-week SMP rule
People who earn below the SMP threshold
People who’ve been working but aren’t strictly employed (e.g. some agency work)

To qualify for Maternity Allowance you need to have:

Been employed or self-employed for at least 26 weeks in the 66 weeks before your due date (these don’t have to be continuous — any 26 weeks)
Earned at least £30 per week for at least 13 of those weeks (verify current threshold on gov.uk)

How much it pays:

Up to £194.32 per week for up to 39 weeks (2026-27 rate)
For self-employed people, the amount depends on the Class 2 National Insurance contributions you’ve paid

The catch for the self-employed: if you haven’t paid enough Class 2 NI, your Maternity Allowance amount drops. Worth checking your NI record with HMRC well before you’re pregnant if you can — it’s possible to make voluntary contributions to fill gaps.

You apply directly to the government (not through any employer), using form MA1 from gov.uk. The application can be done from 26 weeks pregnant onwards.

What if you don’t qualify for either?

You may be entitled to:

Universal Credit — particularly if your household income is low
Sure Start Maternity Grant — a one-off £500 payment if you’re on certain benefits and it’s your first baby

If you’re in this situation, talk to Citizens Advice or a similar service. They’ll work through your specific circumstances. Don’t rely on Google — the benefits system is enough of a maze that personalised advice is worth the time.

KIT days — what they are and whether to do any

KIT (Keeping In Touch) days let you do some work for your employer during maternity leave without ending your maternity leave or losing maternity pay.

The rules:

You can do up to 10 KIT days during your 52 weeks of leave
They’re voluntary — you don’t have to do them, and your employer can’t make you
Likewise, your employer doesn’t have to offer them
You’re paid for the work you do (separate from SMP/Maternity Allowance), at whatever rate you agree with your employer
They can be used for actual work, training, team meetings — anything work-related

Are they worth it? Honest answer: it depends.

If you genuinely want to stay connected to your work, a few KIT days mid-leave can ease the return to work later. Going back after a year cold turkey is a shock.
If your job is your passion and you’ll get itchy not doing it, KIT days can be a release valve.
If your job stresses you out and you’re using maternity leave as recovery, skip them entirely. You’re not obliged.

I’ve had friends who did KIT days, all in the last few months of their leave to help them ease back in. Other friends did zero and were also fine. There’s no right answer.

Shared Parental Leave

Briefly, because most people don’t end up using this, but it’s worth knowing about.

Shared Parental Leave (SPL) lets eligible parents share up to 50 weeks of leave and 37 weeks of pay between them, in the first year after the baby’s born or placed (for adoption). The birth parent has to commit to ending their maternity leave early to free up the weeks.

It’s most useful if:

The non-birth parent earns less and the household needs the income
Both parents want significant time with the baby
Career circumstances make it sensible to share

It’s complicated to set up — both employers need to be notified properly, paperwork has to be filed in advance, and the rules are fiddly. If you’re considering it, start reading well in advance and ask both HR departments early.

Your job rights during and after maternity leave

This is the bit most affects long-term outcomes and most people don’t fully grasp.

During your maternity leave:

Your job is protected. You can’t be made redundant because you’re on maternity leave (though you can be made redundant for other genuine business reasons).
You continue to accrue annual leave at your normal rate. This is significant — you might have weeks of unused holiday when you return. Plan to use it.
Your continuous service carries on. So years-of-service calculations for pensions, redundancy pay, etc. include your leave.
You’re entitled to be kept informed of significant developments at work, including promotions and restructures.

On return:

If you return within the first 26 weeks (Ordinary Maternity Leave), you have the right to your exact same job on the same terms.
If you return between weeks 27-52 (Additional Maternity Leave), you have the right to the same job or a similar job on the same terms, if it isn’t reasonable for you to return to the exact same one.
You have the right to request flexible working. Your employer must consider it seriously and can only refuse on specific business grounds.

Redundancy during maternity leave has special rules. If your role is genuinely being made redundant whilst you’re on leave, you have priority for any suitable alternative role going. This is a real, enforceable right — get advice from an employment specialist if it comes up.

Your pension during maternity leave

This is the bit I lost money on because I didn’t understand it.

For the period you’re being paid (the 39 weeks of SMP/Maternity Allowance):

Your employer continues to pay their full pension contribution based on your normal salary, not the reduced pay you’re getting.
You contribute based on the lower pay you’re actually receiving.

That’s a good deal for you — you’re getting full employer contributions while paying lower personal ones.

For the unpaid period (weeks 40-52):

No statutory requirement for either you or your employer to contribute.
Some employers continue to top up anyway as a benefit. Check.

What I’d do differently: I’d have asked HR a clear question — “what happens to my pension during the unpaid portion of my leave?” — and considered making my own voluntary contributions during that time if the employer stopped. Pensions compound. A year of missed contributions in your 30s costs more in retirement than people realise.

The bits I wish someone had told me

The official guides cover the legal stuff well. They don’t cover the rest. Here’s what I’d have wanted to know.

Maternity leave is not a holiday. I sort of knew this in theory. I did not understand it emotionally. You’re recovering from birth, learning a new human, often surviving on broken sleep, and managing huge identity shifts at the same time. Plan accordingly.

The first few weeks are a blur. Don’t expect to do anything productive in weeks 1-6. The “I’ll read all the books I never have time for” plan is fantasy. You’ll watch a lot of telly.

Money will be tight even if you’ve prepared. A year on reduced income is significant. Even with my employer’s enhanced package, we had to cut back. Budget honestly. Plan months in advance.

You can keep getting holiday pay in lieu. Whatever annual leave you accrued during your maternity year, you take when you return (or it’s paid out). This was a small but useful bonus I hadn’t expected.

KIT days are not the only way to “stay connected”. Reading work-related stuff, popping into the office for a coffee with a colleague, joining the Christmas party — all fine without using a KIT day. KIT days are specifically for actual work.

Your sense of identity will wobble. Lots of women report feeling lost during maternity leave, particularly later in. You go from a recognised professional in your field to “Leo’s mum” overnight. That’s normal. It does pass, but it can take longer than you expect.

Talk to other mums on leave. This was the single most useful thing I did. The baby groups, the WhatsApp threads, the bumping-into-someone-in-Costa. The people going through the same thing at the same time are gold.

Things to sort before you go on leave

The checklist version:

Officially notify your employer in writing at least 15 weeks before your due date (so by 25 weeks pregnant, in practice).
Check your contract for any enhanced maternity package on top of SMP.
Confirm your maternity pay schedule in writing.
Set up a maternity-leave email autoresponder before you go.
Hand over your work properly — don’t leave a mess for whoever covers you. It comes back to bite you.
Sort out childcare for the return — if you’re using a nursery, waiting lists in popular areas can be 6-12 months. Sign up before the baby arrives.
Open or boost a separate savings buffer if you can. Even £500 set aside makes the unpaid weeks easier.
Check your pension situation with HR.
Apply for Maternity Allowance by week 26 if you’re going that route.
Get the MATB1 form from your midwife (around 20 weeks). You need it to claim SMP or Maternity Allowance.
Think about flexible working for your return. Not the day you go back — work it through during your leave.

What returning to work is actually like

A few honest observations from someone who returned (and many friends who have):

The first week back is brutal. Drop-off at nursery, the commute, the meetings, all whilst running on broken sleep. Take annual leave for the second week if you can.
Pumping at work (if you’re still breastfeeding) is a logistics challenge. Find out in advance where you can pump and store milk, and book the time in your diary. Don’t wing it.
Childcare illness will derail you. Nurseries are germ pits in the first six months. Your child will be ill more than you ever imagined. Plan for it; one parent should be able to flex work most months.
You may feel different about work. Lots of women come back and realise they want different things — fewer hours, different role, different career entirely. Give yourself time before making big calls.
It gets easier. The first three months back are the hardest. By month six you’ll have a rhythm.

Frequently asked questions

How long is maternity leave in the UK?

UK statutory maternity leave is 52 weeks — the longest in most developed economies. The first 26 weeks are “Ordinary Maternity Leave” with full job protection; weeks 27-52 are “Additional Maternity Leave” with slightly different return-to-work rules. You can take some, most, or all of the 52 weeks.

How much do you get paid on maternity leave UK?

If you qualify for Statutory Maternity Pay (SMP), you get 90% of your average earnings for the first 6 weeks, then the flat rate (£194.32 per week for 2026-27) or 90% of average earnings — whichever is lower — for the next 33 weeks. The last 13 weeks are unpaid. Some employers pay more than the statutory minimum — always check your contract.

Can I get maternity pay if I’m self-employed?

You may qualify for Maternity Allowance, which pays up to £194.32 per week for up to 39 weeks (2026-27 rate). The amount depends on your Class 2 National Insurance contributions. Apply to gov.uk using form MA1 from week 26 of pregnancy.

What is a KIT day on maternity leave?

A KIT (Keeping In Touch) day is a day where you can do paid work for your employer during maternity leave without losing your maternity pay or ending your leave. You can do up to 10 of them total during the 52 weeks. They’re entirely voluntary on both sides.

When should I tell my employer I’m pregnant?

Legally, by the 15th week before your due date (around 25 weeks pregnant). Many people tell their employer earlier — particularly after the 12-week scan — but the legal minimum is 15 weeks before. You’ll need to give the notification in writing and supply your MATB1 form from your midwife.

Can I be made redundant on maternity leave?

You can’t be made redundant because you’re on maternity leave — that would be discrimination. You can be made redundant for genuine business reasons (e.g. the whole department is being restructured), but you have priority for any suitable alternative role. If this comes up, get advice from an employment specialist or ACAS.
