How to plan a wedding in the UK: the whole thing, step by step

By Dominika5 September 202611 min read

Planning a wedding in the UK comes down to about a dozen decisions made in the right order: how many people, how much money, which date and venue, the legal notice, then the suppliers one at a time starting with the ones that sell out first. Most couples take 12 to 18 months over it, and the order matters more than the pace.

The obvious approach fails because it starts with the venue. A couple falls for a room, signs for it, and then discovers the guest list has to shrink to fit the capacity and every other supplier has to fit the money that is left. Set the size and the budget first and the venue becomes a choice instead of a constraint.

This guide is about how to make each decision well. For the month-by-month calendar of what to book when, use the planning timeline alongside it.

Decide the size and the money together

Guest count and budget are one decision, not two. A UK wedding costs £180 to £280 per guest all in, so 80 guests lands somewhere between £15,000 and £22,000 and 120 guests between £22,000 and £34,000. The national average sits between £20,000 and £25,000, and the full cost breakdown shows where each pound goes. Pick a total you can pay without borrowing, divide by the per-head figure, and you have a first guest count to argue about.

Write down who is contributing what, in pounds, before anyone books anything. A parent who says 'we will help' means anything from £500 to £15,000, and the difference decides the venue. Then split the total: venue and catering take 40 to 50 percent, and the budget breakdown gives worked splits at £15,000, £25,000 and £40,000 so you can see what each line affords.

Hold back 5 to 10 percent as contingency and plan as if it is not there. More than half of couples go over budget, and the overspend is rarely one big mistake. It is VAT missing from a quote, a service charge, twelve evening guests who felt free, and a florist who quoted before you saw the room.

Write the guest list before you look at a venue

The list filters venues by capacity and sets every per-head cost, so it comes before the first viewing. Draft it in tiers: the people the day cannot happen without, the people you would be sad not to have, and the people you would invite if money were no object. Cut from the bottom tier up, and cut by rule rather than by name so nobody can say they were singled out.

  • Decide the day list and the evening list separately. Evening guests cost £25 to £45 each for food and a bar, day guests cost the full per-head figure.
  • Settle plus-ones with one rule for everyone: partners you have met, or relationships past a set length, and no exceptions for the person asking loudest.
  • Decide on children once, for the whole list: all, none, or immediate family only.
  • Expect 10 to 20 percent of invited guests to decline, more for a weekday or a long journey, so a list of 100 usually seats 80 to 90.

When the list is 20 names too long, the tier method and the scripts for the awkward conversations make the cuts consistent and survivable.

Choose the date and the venue as one decision

A fixed date narrows you to whichever venues happen to be free; a flexible window lets you pick the venue and take the best date it has. Saturdays from May to September carry the premium. The same room on a Friday, a Sunday or in October to April is often 15 to 30 percent cheaper, and the difference on a £8,000 hire fee pays for the photographer.

Shortlist by the numbers before you visit anything: capacity for your day list with a dance floor, all-in price for your numbers including VAT, curfew, and whether you can bring your own caterer. Bridebook's UK Wedding Report 2026 found couples enquire with 4 to 10 venues and book after visiting around three, which matches what we see. The shortlist method turns fifty tabs into eight enquiries and three viewings, and the 25 questions to bring to a viewing surface the costs the brochure leaves out.

The enquiries are the slow part. Venues take days to answer, some never do, and the replies come back in different shapes that are hard to compare. Aisley writes to the venues on your shortlist, reads the replies and chases the ones that go quiet, then lays the prices side by side. You choose the room.

Sign only when the contract states the all-in price, the deposit schedule, what happens if either side cancels, and any cap on price rises between now and the day. Popular venues sell peak Saturdays 12 to 24 months out, so a specific summer Saturday needs the long runway.

Book the suppliers in the order they sell out

A supplier who can only do one wedding a day sells out on the same timeline as venues. That means the photographer and the band or DJ first, within a month or two of the venue. Everything else has more supply than demand and can wait its turn.

Months before the wedding for a 12 to 18 month engagement, based on the booking windows suppliers quote us. Compress everything proportionally for a shorter runway; only the notice deadline is fixed in law.

Every supplier deserves the same three checks: a written quote with VAT stated, the deposit and balance dates, and what happens if they fall ill or the date moves. Photographers vary most in what they deliver, so the 20 questions to ask a wedding photographer cover full galleries, backups and image counts. If you are hiring a caterer rather than taking a venue package, the questions to ask a wedding caterer pin down staffing, supplier meals and what the tasting actually commits them to. Deposits typically run 20 to 50 percent, and a deposit paid is a decision made, so pay them in the order above.

Buy wedding insurance the week you pay the first deposit

Wedding insurance covers the money you have handed over if a supplier goes bust, the venue closes, or illness means the day cannot go ahead. It does not cover changing your mind, bad weather on its own, or a supplier who turns up and disappoints. Policies cost roughly £50 to £300 depending on the total sum covered, and they only protect deposits paid after the policy starts, which is why the timing matters: what wedding insurance covers and what it costs sets out the cover levels and the exclusions before you pick one.

Invitations, RSVPs and the admin nobody mentions

Save the dates go out 8 to 10 months ahead and can be an email. Invitations go out 3 to 4 months ahead with an RSVP deadline six weeks before the day, because the caterer wants final numbers around two to three weeks out and a quarter of your guests will need chasing. Put the dress code, the timings, the accommodation options and the gift list on a simple wedding website so the invitation itself stays short.

  • Hold accommodation blocks at two price points near the venue; hotels release unbooked rooms 4 to 8 weeks out.
  • Book coaches if the venue is rural and the last train leaves before the band does. A 50 seat coach for an evening runs £400 to £800.
  • Collect dietary requirements on the RSVP, not by text the week before.
  • Ask two or three people to give speeches early, with a time limit of ten minutes each, and tell them the running order once it exists.
  • Keep one spreadsheet or one planner for every quote, deposit and balance date, so nothing is only in an email thread.

The final month

The last four weeks are about numbers and paper. Confirm final guest numbers with the venue and caterer, chase the RSVPs that never came, and make the seating plan only once the numbers are real, because a plan made early gets remade three times. Pay the balances; most fall due between six and two weeks out, so this is the most expensive month of the whole engagement and the reason the contingency exists.

Two weeks out, write a running order with a phone number for every supplier and the venue, and send it to all of them. Have the final fittings, break in the shoes, and hand the day to someone else: a venue coordinator, a friend who enjoys a clipboard, or a paid on-the-day coordinator for £400 to £900. The couple should not be the people answering the phone on the morning.

The day itself

A well planned day runs on a few fixed durations: the registrar arrives 30 minutes early and needs to speak to each of you, a civil ceremony takes 20 to 30 minutes and a church ceremony 45 to 60, the drinks reception needs 90 minutes, a three course meal with speeches takes two to two and a half hours, and most UK venues turn the music off at 11pm or midnight. Fit those together and there is less room for the day to drift than you would think.

Build 45 to 60 minutes of slack into the day and put it before the fixed points rather than at the end. The wedding day timeline has worked running orders for a 1pm civil ceremony and a 2pm church wedding, the real duration of every segment, and a template you can copy and send to your suppliers. Once it is written and handed over, your only job on the day is to turn up on time and enjoy the people you chose to be there.

Quick answers

How long does it take to plan a wedding in the UK?

Twelve to eighteen months is comfortable and gets you the venue and suppliers you actually want. Six months is workable if you are flexible on the date and venue and decide quickly. The only legal deadline is giving notice at least 29 full days before a civil ceremony in England and Wales.

What should we book first for a wedding?

Agree the budget and guest count, then book the venue, then the photographer and the band or DJ within a month or two. Those three suppliers can each only do one wedding a day, so they sell out on the same timeline. Everything else has more supply than demand.

How much should we budget for a wedding?

Plan on £180 to £280 per guest all in for a UK wedding in 2026, so 80 guests lands between £15,000 and £22,000. Hold back 5 to 10 percent as contingency, because more than half of couples go over budget and the overspend is usually many small quiet costs rather than one big one.

Do we need a wedding planner?

Most UK couples plan without one. A full planner typically costs 10 to 15 percent of the budget and earns it on large, complex or destination weddings. An on-the-day coordinator for £400 to £900 covers the part most couples find hardest, which is running the timeline while trying to enjoy their own wedding.

In what order should we make the big wedding decisions?

Size and money first, guest list second, then the date and venue as one decision, then the legal notice, then suppliers in the order they sell out: photographer and music, then caterer, outfits, florist, and the rest. Invitations go out three to four months ahead and the final month is for numbers, balances and the running order.
