Planning a kids party in London can feel like a lot — venues book up fast, everyone’s busy, and you don’t want the day to turn into organised chaos.
This guide gives you a simple timeline and checklist you can follow, whether you’re planning a living-room party, a community hall, or a venue in your local borough.
If you’re here because you’re considering entertainment, I’ll also explain when to book a children’s magician and what to ask so you get the right fit for your child’s age.
The quick answer: when should you start planning?
- 6–8 weeks before is ideal if you want the best choice of venues and entertainers
- 4 weeks before is doable if you keep it simple
- 2 weeks before is possible, but you’ll need flexibility on time, venue, and entertainment
- Last minute? – It doesn’t hurt to check availability.
In London, the biggest bottleneck is usually availability (venues + entertainers), not the party supplies.
Kids party planning timeline (London-friendly)
6–8 weeks before: lock the date + the “big 2”
1) Choose the date and time
For many families, the easiest slot is:
- Saturday or Sunday, late morning to early afternoon
- 2 hours is plenty for most age groups
2) Pick the venue (if not hosting at home)
London venues can vary a lot. When you message a venue, ask:
- Capacity (kids + adults)
- Tables/chairs included?
- Kitchen access?
- Parking / loading
- Sound system (useful for entertainment)
3) Book entertainment early
If you’re looking at entertainment, book it now. This is the stage where you’ll still have options.
If you’re searching for a magician for hire in London, your best approach is to shortlist 2–3 and secure a date with the one that matches your child’s age and party vibe. (More on that below.)
4–5 weeks before: invites + party structure
4) Send invites
Decide what you’re doing:
- Paper invites (nice, but slower)
- WhatsApp message + RSVP (fastest)
- E-vites (best of both)
Keep it simple:
- Date, time, address/postcode
- RSVP deadline
- Any key info (allergies, parking, drop-off policy)
5) Plan the party “flow”
Most kids parties go better with a clear structure:
- 0:00–0:15 — arrivals + free play
- 0:15–0:45 — entertainment / main activity
- 0:45–1:05 — food
- 1:05–1:35 — games / music / second activity
- 1:35–2:00 — cake + goodbyes
If you’re having a magician, they usually work brilliantly either:
- early (to settle everyone), or
- mid-way (as the main feature)
2–3 weeks before: food, cake, and “boring but important”
6) Food that won’t stress you out
You do not need a full spread. London-party classics:
- Pizza slices / sandwiches
- Fruit + crisps
- Simple allergy-safe options
7) Cake
If you’re ordering a custom cake, do it now. If not, supermarket + decorations is fine.
8) Party essentials checklist
- Candles + lighter
- Bin bags + wipes
- Disposable table covers
- Small first-aid bits (plasters)
- Phone charger / speaker (if needed)
7–10 days before: confirmation week
9) Confirm attendance
Chasing RSVPs is normal. A quick “final numbers by Friday please” message works.
10) Confirm venue and entertainment
Double-check:
- Start time and end time
- Parking / access
- Any special requests (music volume, microphone, space needed)
48 hours before: set yourself up for an easy day
11) Prep a “party box”
Put everything in one box/bag so you’re not hunting around:
- Decorations
- Candles
- Plates/cups
- Party bags
- Cake knife + serviettes
12) Set a simple boundary
If it’s a drop-off party, write it clearly. If it’s stay-and-play, say that too. It avoids awkwardness on the day.
Booking a children’s magician in London: what to ask (so it goes well)
A magician can be an amazing choice because it gives the party structure and keeps kids engaged.
When you message a children’s magician, ask:
- What age range is it best for?
- How long is the show? (and what happens around it)
- Do you need any setup space?
- How do you handle shy children or high-energy groups?
- Is it interactive? (kids love being involved)
- What’s included in the price? (travel, time, extras)

And if your party is mainly younger children, the most relevant page is your children’s party magician service page.

Common London kids party mistakes (and how to avoid them
Mistake 1: too long
Two hours is usually the sweet spot.
Mistake 2: no structure
Kids parties run smoother with a clear plan (arrivals → activity → food → cake).
Mistake 3: leaving entertainment too late
In London, the best entertainers book ahead — especially weekends.
Mistake 4: overcomplicating food
Simple wins. You want “easy to serve” more than “impressive”.
