Quick answer: Christmas Jumper Day 2026 is Thursday 10 December 2026. It is run by Save the Children, who ask workplaces, schools and community groups to wear a Christmas jumper for the day and donate. You can run yours on a different date if that suits your calendar better. If you want branded or personalised jumpers rather than shop-bought ones, order in late October or early November and approve your proof by around Friday 20 November.
Every year the same thing happens. Someone in the office remembers Christmas Jumper Day in the last week of November, a flurry of panic-buying follows, and half the team turns up in the same supermarket reindeer jumper. It does not have to go that way, and the fix is almost entirely about getting the date in the diary early.
This is the practical version: the confirmed date, what actually happens on the day, and how to organise one properly whether you are running it for a twelve-person office or a whole primary school.
When is Christmas Jumper Day 2026?
Thursday 10 December 2026. That is the official date published by Save the Children, who run the event.
One thing worth knowing: a lot of pages online still show 11 December, which was based on last year's pattern rather than this year's announcement. If you have already put 11 December in a newsletter or a parent letter, that is the correction to make now rather than in December.
Can we run ours on a different day?
Yes. Save the Children explicitly say that if another day works better for you, go for it. Schools often move it to the last day of term. Offices with a hybrid pattern usually pick whichever day has the most people in, because a Christmas jumper photo with four people in it is a sad thing. Pick the day your people are actually together.
What Christmas Jumper Day actually is
Christmas Jumper Day is Save the Children's biggest annual fundraising event. It started in 2012 and has raised more than GBP 42 million since, including GBP 2.6 million in 2025 alone. The premise is simple: wear something festive, donate what you can afford, and the money goes towards helping children in the UK and around the world stay safe, healthy and learning.
The low barrier is the whole point. There is no minimum donation, no committee required, and nobody has to run anywhere. That makes it one of the easiest fundraisers a workplace or school can run, which is precisely why so many do.
How to organise Christmas Jumper Day at work
- Pick your date and claim it now. Put it in the shared calendar today, not in November. December diaries fill up fast and a clashing all-day workshop kills the turnout.
- Sign up with Save the Children. They send a resource pack with posters, activities and a fundraising page, which saves you designing anything yourself.
- Decide how you are collecting. A JustGiving page beats a tin on a desk, because people can give from their phone and it keeps running after the day. Ask whether your employer will match what is raised - many will, and nobody thinks to ask.
- Decide on jumpers early. This is the step that gets left too late. More on it below.
- Give people something to do. A best-jumper vote, a photo wall, a bake sale alongside it. Turnout is far higher when there is a reason to be seen in the thing.
- Take the photo. Genuinely. It is the thing that gets people to join in next year, and it is the only marketing you will ever need for an internal event.
How to organise it at a school
Schools have a slightly different job, because you need parents to act rather than colleagues. The things that make the difference:
- Tell parents at least three weeks out, and tell them twice. One letter in November and one reminder the week before.
- Be explicit about what counts. "Any festive jumper, or a normal jumper with tinsel on it" removes the pressure to buy something new, which matters enormously to some families.
- Suggest secondhand. Save the Children push this too. It removes cost as a barrier and it is a better story than a pile of new acrylic.
- Set the donation low and fixed. A suggested GBP 1 raises more than an open ask, because nobody has to decide what is appropriate.
- Consider one designed jumper for staff. A single staff design in school colours, worn every year, costs less over three years than three rounds of individual purchases and looks far better in the photos.
Christmas jumper day ideas that raise more
- Best and worst jumper prizes. Two categories, because the worst one is the one everyone remembers.
- Pay to opt out. A small donation to wear normal clothes. Surprisingly effective, and it lets people who genuinely hate it take part anyway.
- Departmental teams. Sales versus operations, with a leaderboard. Competition raises more than goodwill does.
- A jumper for the year, not the day. A designed jumper the team keeps and wears each December turns a one-day gimmick into a small tradition.
- Sell the jumpers as the fundraiser. Clubs and societies do this well - the margin on each one goes to the charity, exactly as clubs do with custom t-shirts for a fun run or summer fundraiser.
The bit people leave too late: the jumpers themselves
If you are buying off the shelf, you can leave it until the first week of December and take your chances on sizes. If you want your own design - a logo, a team name, the year, individual names on the back - you need a longer runway, and it is not because suppliers are being difficult. It is because artwork, proofing and production each take real time.
A workable timeline for Thursday 10 December 2026:
- Late October: agree that you are doing branded jumpers, get a rough headcount and set the budget.
- Early November: send your logo and any names list to your supplier, and get a quote. Our guide to preparing your logo for embroidery and printing explains what file to send so this step does not bounce back.
- By Friday 20 November: approve the digital proof. That is fourteen working days before the day itself.
- Early December: jumpers arrive with time to sort them into sizes and hand them out.
The two things that hold orders up are almost always the same: an unusable logo file, and a names list that arrives late or with spellings nobody has checked. Sort both in early November and the rest is straightforward. If you are planning other festive spend at the same time, our business calendar for branded Christmas merchandise maps out the full autumn timeline.
Shop-bought or your own design?
Be honest about which one you are actually doing.
Shop-bought or secondhand is right if the point is purely the fundraising, the group is large and informal, or the budget is genuinely nil. It is also the greenest option, and Save the Children recommend it.
Your own design is right if you want the jumper to survive December - staff kit, club colours, a year group that wants a keepsake, or a business that will be photographed in it. A designed jumper gets worn again; a novelty one usually does not. If that is the route, our personalised Christmas jumpers page covers print and embroidery options, and you can see the base garments in our hoodies and sweatshirts range.
Frequently asked questions
When is Christmas Jumper Day 2026?
Thursday 10 December 2026.
Do we have to do it on the official date?
No. Save the Children encourage groups to pick whatever day works best for them. The official date just gives everyone a common reference point.
What qualifies as a Christmas jumper?
Anything festive. There is no standard and no judging panel. A knit, a sweatshirt, a hoodie, or an ordinary jumper with something festive added all count. Being relaxed about this is what gets turnout up.
How long do personalised Christmas jumpers take to make?
Allow six to eight weeks end to end to be comfortable. Production itself is typically 7-14 working days from the point you approve your proof - the rest of the time goes on artwork, gathering sizes and getting a decision made.
Is there a minimum order for branded jumpers?
At CentralCustom, no. Larger quantities bring the unit cost down, but there is no minimum, so a small team is not shut out.
Getting your jumpers sorted
Christmas Jumper Day works because it asks very little of people. The only part that needs planning is the jumpers, and only if you want your own design on them. Decide that in October, and December takes care of itself.
If you want a quote, tell us your quantity, rough sizes, deadline and what you want on the jumper, and we will come back within a working day - normally with an honest view on whether your timeline is realistic. Get in touch or email promo@centralcustom.co.uk. If you are also sorting gifts for clients or staff, our corporate Christmas gifts range is worth a look while you are at it.
