Two large UK surveys published in 2026 put the average wedding at £20,604 (Bridebook, from around 7,000 couples) and £21,990 (Hitched, from 2,020 couples married in 2025). Both are honest numbers and neither tells you what yours will cost.
The reason is that an average hides an enormous spread. Around a quarter of UK couples spend £10,000 or less, and most land somewhere between £10,000 and £30,000. A single average sitting in the middle of a range that wide describes almost nobody.
What is useful is knowing where the money goes and which decisions move it.
Where the money actually goes
One category dominates and it is not close. Venue and catering together account for roughly half of a typical UK wedding.
| Category | Typical cost |
|---|---|
| Venue hire | Around £5,900 |
| Catering and reception | Around £5,400, or roughly £60 to £120 per head for three courses with drinks |
| Photography | £1,200 to £2,000 for full-day coverage |
| Everything else | Flowers, cake, attire, stationery, music, transport and rings — individually small, collectively substantial |
The three decisions that move the number
Almost every meaningful saving traces back to one of three choices, and all three are made early.
- Guest count. Catering is charged per head, so every name on the list is a recurring cost that also drives the venue you need, the size of the cake, the number of favours and the transport. Cutting twenty guests at £90 a head is £1,800 before anything else follows it. This is the lever with the longest reach and it is the one people revisit last.
- Day of the week. The 2026 survey figures put a Saturday wedding at an average of £22,290 against £16,273 for a Tuesday. That is roughly a quarter off the whole wedding for a decision that changes nothing a guest sees, though it does change who can attend.
- Season. Peak season in the UK is May to September and venues price accordingly. A winter wedding at the same venue with the same food can cost meaningfully less, and the rooms often look better for it.
What couples underestimate
The overspend is rarely the big items, which get researched carefully. It is the accumulation of things that were never given a line.
- Drinks beyond the package — a welcome drink, wine on the table and a toast are often three separate charges
- Supplier meals, which the venue will charge for and the contract usually requires
- Corkage, if you are bringing your own
- Overtime, if the evening runs past the contracted finish
- Postage, which is invisible until you post 90 invitations
- Alterations, which are rarely included in the price of the dress
- Payments to the register office, which are separate from the venue entirely
Building a budget that survives contact
Set the total first, before looking at a single venue. Deciding what you can spend after falling in love with a room is how budgets get rewritten upwards, and it only goes one direction.
Include family contributions only when they have actually been offered in a specific amount. A budget built on an assumed contribution is a budget with a hole in it.
Then hold back ten percent. Not for emergencies — for the ordinary, entirely foreseeable extras above, which arrive at every wedding and are only surprising the first time.
Track it against real numbers as you go rather than at the end. A wedding budget tracker that sits with the rest of your planning is more use than a spreadsheet you have to remember to open, mostly because it gets updated at the moment a supplier confirms rather than three weeks later.
Where to save without anyone noticing
Guests notice the food, the drink, the music and whether they were looked after. They do not notice the things that absorb budget quietly.
Favours are the clearest example: they cost per head and are frequently left on the table. Elaborate stationery is admired for a moment and recycled. Multiple floral installations photograph much like one good one. Transport for the whole party is often replaced by a postcode and a taxi number.
The saving nobody notices at all is the day of the week. A Friday or a Tuesday changes the number more than every cut above put together, and the only thing a guest experiences differently is which day they book off.
