People don't ask this question because they're cheap. They ask because nobody tells them, and the internet gives them numbers that don't mean anything. American averages, vague ranges, lists that somehow manage to say everything and nothing at once.
So here's a straight answer from someone who actually quotes and makes wedding florals in London, Ontario.
Personal flowers
For personals only (a bridal bouquet, bridesmaids, boutonnieres and corsages, picked up from the studio) you're looking at somewhere between $600 and $1,800 depending on the size of your party. That's real flowers and designed work, made the week of your wedding.
Ceremony installations
Add a ceremony installation and you're starting around $2,000. A meaningful arch, something lush and considered, sits closer to $3,500 to $4,500. The installations that actually stop people, the ones that look like they grew there, cost more than that.
Full service
Full service means personals plus ceremony plus reception tablescapes, with delivery and setup. My full-service weddings start at $4,500. Most weddings that want all of it done well land somewhere between $5,000 and $8,000, and large-scale or heavily designed work goes beyond that.
Why there's no clean number
The number doesn't exist until someone knows what you're actually building. Two weddings with the same guest count can have wildly different floral budgets depending on whether one wants bud vases and the other wants compote arrangements and hanging installations. Labour, materials and complexity drive the cost, not how many people are coming to dinner.
The things that move the number most: the size of your bridal party (each bouquet is real work), the scale of your ceremony installation (often the largest single line item), whether your ceremony and reception are in the same space (it changes what can be moved and reused), and what the season is actually offering. Asking for flowers that aren't growing anywhere near here in October is going to cost more than working with what's honest to the time of year.
The thing most couples underestimate is setup. A florist doing full-service work is at your venue for hours, transporting work that took days to prepare, placing each piece and often coming back to collect everything afterward. That time is part of what you're paying for.
A realistic starting budget
If you're planning a wedding in London and trying to set a realistic budget before reaching out to anyone: allow at least $1,500 if you want personal flowers only, at least $2,500 if you want a ceremony element, and at least $4,500 if you want the whole day considered. Those numbers won't get you everything, but they'll get you something honest.
If you want to talk through what's possible for your day, the enquiry form is the place to start. Bring your budget. A good florist will tell you what's realistic within it.
