How Much Does a Kids' Party Cost in 2026? A Realistic Breakdown

Planning a kids' birthday party is exciting — until you start adding up the costs. Between venue hire, entertainment, food, cake, decorations, and party bags, it can feel like the budget is spiralling before you've even sent the invitations.

So, how much does a kids' party actually cost in 2026?

The honest answer: it depends. But we've put together a realistic breakdown to help you understand where the money goes — and how to plan a party that fits your budget.

The Short Answer

For a typical children's birthday party with 15–20 guests, you can expect to spend somewhere between £300 and £600 in total — depending on your choices.

Let's break that down category by category.

Venue Hire: £0–£200

If you're hosting at home, this cost is £0. But if you need more space (or want someone else to deal with the mess), you'll likely hire a hall or community centre.

Typical costs:

• Church or community hall: £50–£100 for 2–3 hours
• Village hall: £60–£120
• Soft play or activity centre: £150–£300 (often includes entertainment)
• Private party room at a venue: £100–£250

Entertainment: £100–£250

Entertainment is often the biggest single expense — and the thing that makes the party memorable. The price depends on what you book and for how long.

Typical costs:

• Children's entertainer (1 hour): £120–£180
• Magician: £150–£200
• Character entertainer (e.g., princess, superhero): £150–£250
• Disco or DJ: £100–£180
• Face painter (1–2 hours): £80–£120
• Balloon artist: £80–£120
• Soft play or bouncy castle hire: £80–£150

Food and Drink: £50–£150

You can go as simple or as elaborate as you like. Most kids are happy with classic party food — sandwiches, crisps, fruit, and a few sweet treats.

Typical costs:

• DIY party food (supermarket bought): £30–£60
• Party platter from a caterer or supermarket: £50–£100
• Pizza delivery: £60–£100
• Full catering: £100–£200+
• Drinks and juice boxes: £10–£20

Birthday Cake: £30–£100

The cake is the centrepiece of any birthday party. Costs vary wildly depending on whether you bake, buy, or commission something custom.

Typical costs:

• Homemade: £10–£20 (ingredients)
• Supermarket celebration cake: £15–£30
• Custom cake from a local baker: £50–£100+
• Elaborate themed or tiered cake: £100–£200+

Decorations: £20–£80

Balloons, banners, tablecloths, and themed bits and pieces. You can do this cheaply if you keep it simple — or go all-out with professional balloon displays.

Typical costs:

• Basic decorations (balloons, banner, tablecloth): £15–£30
• Themed party kit (plates, cups, napkins, decorations): £20–£40
• Balloon arch or professional display: £50–£150
• Party styling package: £100–£300+

Party Bags: £30–£60

Most parents feel obligated to send children home with something. Party bags can be as cheap or expensive as you make them.

Typical costs:

• Simple sweet bags: £1–£2 per child
• Standard party bags with toys and sweets: £2–£4 per child
• Premium or themed party bags: £5–£8 per child

Invitations: £0–£20

Digital invitations are free. Printed cards or themed invites add a bit extra, but it's usually a minor cost.

• Digital invite (Canva, email, WhatsApp): Free
• Printed invitations: £5–£15
• Custom or premium invitations: £15–£30
