The short answer: book a London wedding planner 12–18 months ahead for a full-planning wedding, and at least 3–6 months ahead for day coordination — though the best planners and venues get reserved earlier, especially for peak dates and multi-day celebrations.
The ideal lead time depends on the service and the complexity of your celebration. Earlier is almost always better: it opens up venue availability, locks in your preferred suppliers, and gives design and logistics room to breathe.
Full planning: 12–18 months
This gives time to set the budget, secure the venue and build the supplier team without pressure.
Partial planning: 6–9 months
Ideal if you've made a start and want a professional to bring it together.
Day coordination: 3–6 months
Enough time to absorb your plans and run the day flawlessly.
Multi-day & peak dates
Multi-day and multicultural celebrations, and popular summer dates, warrant booking as early as you can.
