Wedding Cost Calculator (Detailed)

Total wedding cost depends heavily on three factors: guest count, location and style. Each additional guest adds £70–£150 in catering and the costs that follow from it, a London venue can cost two to three times more than an equivalent rural venue, and a formal sit-down dinner costs significantly more than a buffet or afternoon tea reception. Those three levers explain most of the gap between one couple's budget and another's.

This calculator estimates the total from your guest numbers, region, meal style and supplier preferences, drawing on current UK pricing and returning a low, mid and high figure so the effect of each choice is visible rather than buried. It also sets your estimate against regional averages, which helps you decide where to concentrate spending and where a saving will pass unnoticed by everyone in the room.

The Hitched 2025 survey put the average UK wedding at £20,775, excluding rings and honeymoon, with the median couple at £18,500. Spending divides fairly predictably, with the venue taking 35-40%, food and drink 25-30%, photography 8-12%, dress and attire 6-10%, flowers 4-7%, entertainment 4-6% and transport 2-3%. On top of that sit the honeymoon at £3,500-£8,000 and rings at £1,000-£3,000, of which the engagement ring alone averages £2,750. Region moves everything, since London runs 40-60% above the national average while Scotland and the North East come in 20% below.

Venue hire is the first big decision and the widest price band on the list. A country hotel charges £2,500-£8,000 for hire alone, a historic stately home £5,000-£20,000 or more, a barn or farm £2,000-£6,000, and a hotel ballroom £3,000-£10,000. Cheaper routes are often overlooked. A restaurant taken privately runs £500-£3,000 depending on the minimum spend, and a pub function room only £200-£1,000. A marquee in a family garden costs £1,500-£5,000 for the structure before any catering is arranged. London venues carry a premium of 50-100% over national rates.

Catering is the largest variable, because it multiplies by the guest list rather than sitting as a flat fee. Budget catering runs £45-£90 a head, mid-market £90-£150 and premium £150-£250 or more, so 80 guests can mean anything from £3,600 to £20,000 for food alone. A drinks package adds £20-£60 a head for reception drinks, wine and a toast. Booking a dry-hire venue and bringing in your own caterer typically comes in 30% cheaper than the venue's own package, and supplying your own alcohol against a corkage charge of £8-£15 a bottle saves more again. A buffet costs 20-30% less than a three-course plated dinner.

Everything else adds up faster than couples expect. Photography is £1,200-£3,500 at mid-range and £4,000-£10,000 or more at the top, with videography usually billed separately at £1,500-£5,000. A DJ costs £400-£900 and a four or five piece live band £1,500-£3,500. Florists charge £400-£2,500, a three-tier cake £200-£800, stationery £150-£500, hair and makeup £400-£1,500 in total, wedding car hire £300-£800, and a day-of coordinator £500-£1,500. Wedding insurance is £80-£250 and covers cancellation for illness, supplier failure and venue closure, with public liability up to £2M, though never a change of heart.

The savings that actually work are structural rather than fiddly. Marrying midweek between Monday and Thursday cuts venue prices by 30-50%, and going off-season between November and March saves 20-40%. Pairing a dry-hire venue with an independent caterer is worth £3,000-£8,000. Making your own stationery saves £100-£300, swapping flowers for greenery £200-£500, and accepting help from friends and family with the cake, hair or photographs £500-£2,000. Cutting the guest list from 100 to 50 saves in a straight line on catering. A dress bought online costs £200-£800 against £1,500-£5,000 in a bridal shop. On those choices a UK wedding at £8,000-£15,000 is realistic.
