The short answer: in London, full wedding planning typically runs as a percentage of your overall budget (often around 10–15%) or a fixed fee, while day-coordination packages start much lower. The right figure depends on guest count, number of events and how much you want handled.
Wedding-planner pricing in London usually follows one of three models: a percentage of total spend, a flat project fee, or per-service packages (planning, design, coordination). Full planning costs more because it covers everything from budgeting and venue sourcing to supplier management and on-the-day delivery. Partial planning and day coordination cost less because they cover a narrower slice.
What actually moves the price
Guest count, the number of functions (a single reception versus a three-day celebration), venue complexity, and how bespoke the design is. A 300-guest multi-day celebration naturally involves more coordination than an intimate dinner.
Is a planner worth it?
A good planner typically pays for themselves through supplier relationships, avoided mistakes, and the time and stress they remove. The real value is on the day: you get to be a guest at your own celebration.
