You set a budget, you split it neatly across venue, food, dress and photographer, and you feel quietly smug about how organised you are. Then the little costs start arriving. None of them feels huge on its own. Together they can add a four-figure surprise to the bill. According to Hitched's 2024 National Wedding Survey, more than half of couples (51%) went over their budget, and it's rarely the venue that does it. It's the bits nobody mentioned.
Here's where the money quietly leaks, and how to catch it before it does.
Postage, printing and the paper trail
Invitations get budgeted for. Postage almost never does. If you're sending 70 invitations and a large or thick envelope tips you into the next stamp bracket, you're paying a couple of pounds per guest just to post the things. Save-the-dates, RSVP cards with stamped return envelopes, thank-you cards and the postage on all of them: it adds up fast.
Then there's the extra printing you forget. Order of service sheets. Table plans. Place cards. Menu cards. Signage. A couple of rounds of "actually, can we change the wording" with a printer who charges per amend. None of it is dear individually, but a stationery budget of £150 has a habit of becoming £400.
A wedding website takes a real bite out of this. Pop your timings, directions, dress code and FAQs online and you can drop most of the printed paper entirely, and collect RSVPs digitally rather than posting cards back and forth.
The supplier extras hiding in the small print
This is where the proper money lives. Read every quote to the last line, because the headline price is often just the start.
- Corkage. Bringing your own wine to save money? Some venues charge £10 to £20 a bottle to open it for you. Do the sums before you assume BYO is cheaper.
- Cake cutting fee. Yes, this is real. Some venues charge to cut and plate a cake you've already paid for.
- Overtime. Bands, photographers and venues often run to a fixed finish time. Want the bar open another hour, or the photographer to stay for the first dance? That's an extra fee, usually agreed on the night when you're least inclined to argue.
- Service charge and VAT. A catering quote of "£65 per head" can become £85 once service charge and VAT land on top. Always ask whether a price is inclusive.
- Delivery, setup and collection. Hired furniture, flowers and decor often come with separate charges to bring them, build them and take them away again.
Beauty, alterations and the things that need doing twice
Dress alterations are the classic underestimate. A gown rarely fits straight off the rail, and proper tailoring (taking in, hemming, bustle work) can run from £150 to £400 depending on the dress and how much needs doing. Build it in from the start.
Then come the trials. The hair trial, the makeup trial, the tasting if it isn't included. Most of these are charged separately. Add nails, a spray tan, a fresh haircut for the groom, and possibly the same again for anyone in the wedding party you've offered to treat.
| Hidden cost | Typical UK range | Often forgotten because |
|---|---|---|
| Dress alterations | £150 to £400 | Assumed to be included |
| Postage (all stationery) | £80 to £250 | Priced per stamp, never totalled |
| Corkage | £10 to £20 per bottle | Sold as a money-saver |
| Hair and makeup trials | £80 to £200 | Booked separately from the day |
| Supplier overtime | £150 to £500+ | Agreed on the night |
| Marquee extras (loo hire, power) | £500 to £2,000 | Hidden behind "blank canvas" |
Tipping, transport and the day-of bits
Tips aren't obligatory in the UK, but most couples like to thank the people who pulled the day off. Set aside something for the band, the caterers, the toastmaster, the hair and makeup team. Even at modest amounts, that's a few hundred pounds you didn't account for.
Transport is another one. Getting yourselves to the venue is obvious. Getting elderly relatives between the ceremony and reception, or laying on a coach so guests can drink and not drive, is a kindness that costs real money. Don't forget the morning-after logistics either.
And the marquee or tipi crowd: "blank canvas" is the most expensive phrase in weddings. A field gives you nothing. You're hiring loos, generators, lighting, flooring, heating and possibly a water supply. A venue that looks cheaper on paper can cost more once it's actually usable.
How to stop the leaks
Build a contingency line of around 10% from day one and protect it. Don't spend it on a nicer dessert in month three.
When a quote arrives, reply with one question before you sign: "Is there anything else I'll be charged for on the day that isn't on this quote?" Ask it of every supplier. The honest ones will tell you straight, and the answer often reveals the corkage or the overtime clause you'd have found out about too late.
Keep everything in one running total rather than a dozen separate notes. Build The Day's budget tracker lets you log deposits, balances and the little extras as they crop up, so the real number is always in front of you. The couples who don't get caught out aren't the ones who spend less. They're the ones who saw the whole picture early.
