How to plan a wedding

Every wedding, however grand or small, comes together in roughly the same order. Get the big decisions right early - budget, guest count, date, venue - and the smaller ones tend to fall into place behind them. This guide walks through that order, step by step, so you always know what to do next. If you would rather work from a list than an article, our free wedding checklist covers the same ground task by task.

Start with the two numbers that decide everything

Before you look at a single venue, agree two numbers with whoever is paying: your total budget, and roughly how many guests you want. Almost every later decision - which venues you can afford, how many vendors you can book, whether Saturday in June is realistic - flows from these two figures. Couples who skip this step tend to fall in love with a venue or a dress first, then discover it does not fit either number.

If you are not sure what a realistic budget looks like, our guide to average wedding costs in the UK gives a sense of what things typically cost, and the wedding budget calculator will split a total budget into sensible category-by-category amounts in a couple of minutes. It is worth revisiting both numbers once you have a shortlist of venues, since venue and catering costs usually move together.

Pick a date and book the venue

With a budget and a guest count settled, choose a season first, then a date, then a venue. Popular venues and Saturdays in peak season (roughly May to September) are often booked twelve to eighteen months in advance, so this is usually the first major booking couples make. Being flexible on the day of the week, or choosing a shoulder-season month, can open up venues that would otherwise be out of reach on budget.

When you visit venues, ask what is included in the price - tables, chairs, a getting-ready room, an in-house caterer - since a lower headline price with everything extra can end up costing more than a higher one that includes it. Get the venue's final quote in writing before you put down a deposit.

Sort the legal bits

In England and Wales, you need to give notice of marriage at your local register office at least 29 days before the wedding, and you can do this up to 12 months ahead - it is worth booking your notice appointment as soon as your date is fixed, since some register offices have their own waiting lists. Both partners normally need to give notice in person, at the register office covering where they live, even if the wedding itself is elsewhere.

Alongside notice, decide what kind of ceremony you want, since this determines who can legally marry you: a civil ceremony at a register office or approved venue, a religious ceremony at a licensed place of worship, or - for many venues - a legal ceremony followed separately by a blessing or symbolic ceremony elsewhere. Rules differ slightly in Scotland and Northern Ireland, so check with your local register office if you are marrying outside England or Wales.

Build your timeline

Once the venue and legal notice are in hand, sketch a timeline working backwards from the wedding date. As a rough shape: book major vendors and send save-the-dates in the first few months after the venue is confirmed, handle dress and suit fittings and send formal invitations in the middle stretch, and leave the final six to eight weeks for confirmations, seating and the finer details rather than big decisions.

A written timeline, kept somewhere you and your partner both check, is what stops planning from feeling like a constant background worry. This is exactly the kind of thing an AI planning assistant is good at - it can suggest a sensible order of tasks based on your date and draft reminders as deadlines approach, though it is always you who decides what to book and when.

Book the key vendors

Photographers tend to book up furthest in advance, followed by catering, then flowers and music - so it is sensible to approach vendors roughly in that order once your date and venue are fixed. For each one, get at least three quotes for a genuinely comparable brief: same hours, same deliverables, same guest count, so you are comparing like with like rather than a cheap quote that covers less.

Read reviews, ask to see a full gallery or set list rather than just highlights, and confirm what happens if a vendor is ill or unavailable on the day. A written contract with a clear cancellation policy is worth more than a good feeling in a first meeting.

Guests, invitations and RSVPs

Firm up your guest list early, since it affects venue capacity, catering costs and seating later on. A common rhythm is save-the-dates around eight to twelve months before the wedding - earlier if many guests are travelling - followed by formal invitations three to four months out, with an RSVP deadline of six to eight weeks before the day.

Track responses, dietary requirements and plus-ones in one place from the start, rather than piecing them together from messages and emails close to the deadline. This is one of the more tedious parts of planning, and one of the easiest to hand to a shared tool rather than a single spreadsheet only one of you can access.

The final months and the week of the wedding

In the last two months, confirm final numbers, timings and any special requirements with every vendor in writing, and build a simple day-of running order - who arrives when, and who is holding what. Delegate the small jobs (collecting the cake, briefing suppliers on the day, keeping an eye on the time) to people you trust, so you are not the one carrying them.

In the final week, aim to protect a couple of quiet evenings rather than fill every hour with jobs. Most of what still needs doing by then is confirmation, not decision-making - and a plan you trust is what makes that possible.
