Twelve months is a comfortable amount of time to plan a wedding. It is also just enough time to spend eleven of them worrying about the wrong things. Order matters more than effort: a small number of decisions have to happen early because everything else hangs off them, and a lot of what fills up wedding checklists can wait until the last two months with no harm done.
What follows is a realistic spine. Shift the months to fit your date, not the other way round.
Before you book anything: three rough answers
You cannot sensibly look at venues until you can answer three questions, at least roughly. How many people. How much you can spend. Roughly where.
Guest numbers move everything else, so start there even though it is the hardest. A list of 60 and a list of 140 are not the same wedding at two sizes — they are different weddings, with different venues, different catering and a different amount of noise in the room.
On money, resist building a forty-line spreadsheet on day one. Start with the total you can genuinely reach, then accept the shape of it: venue hire and feeding people take the biggest share by a distance, with photography, drinks and music usually next. Stationery, flowers, favours and transport are small by comparison and flex easily. Pick the two or three things you actually care about, let those be the expensive ones, and be honest that something else has to give.
Months 12 to 10: the things there is only one of
Book anything where there is exactly one of it and other couples want the same Saturday: the venue and date, the registrar or vicar, and the two or three suppliers whose work you would be sad to lose.
If you are having a civil ceremony at a licensed venue in England or Wales, the registrar is a separate booking from the venue. Registrars come from the register office for the district the venue sits in, not the one you live in, and they do run out. A venue with your date free is no use if no registrar is available that afternoon — hold both before paying a deposit on either.
Then the suppliers who only take one wedding a day: photographer, videographer, band. If your venue is dry hire — a village hall, a barn, a marquee in a field — the caterer belongs in this group too, and so does the marquee company, along with the unglamorous list nobody thinks about until too late: power, loos, lighting, parking and a wet-weather plan.
If you are marrying in a Church of England church
Talk to the vicar as early as you talk to venues. Most couples marry after banns, read out in church on three Sundays during the three months before the wedding — in your parish, your partner's parish if it differs, and the church where you are marrying. The readings happen late; the conversation and the booking happen now. If neither of you lives in the parish you may still be eligible through a qualifying connection, and where banns will not work a common licence is the usual alternative. Ask the vicar — they deal with this every week.
Months 10 to 7: long lead times
Made-to-order bridalwear is the classic long lead item — ordered, then made, then altered, with a queue in front of every stage. If you are buying off the peg, hiring, or wearing something you already own, this section shrinks to an afternoon and can move later. Menswear needs less runway than people fear.
Save the dates are optional. They earn their place when guests need to book flights, take leave or arrange childcare far ahead. They are not a soft invitation: anyone who receives one has to receive an invitation, so do not send them until the guest list is settled.
This is also the moment for wedding insurance, which is cheap relative to what it covers, and for the conversation with parents about who is contributing what — before it becomes a conversation about who gets to invite whom.
Months 7 to 4: the middle stretch
Flowers, cake, transport, hair and makeup trials, accommodation held at nearby pubs and hotels, and whatever fills the gap between the wedding breakfast and the evening. None of it will vanish if you wait, but all of it is easier now than in a rush later. This is also where the guest list stops being a number and becomes actual names, which it has to before invitations can happen.
Months 4 to 2: the legal bit and the invitations
In England and Wales you both give notice in person at the register office for the district where you live, and you must have lived there for at least seven days first. Your notice is then displayed publicly for 28 days before the authority to marry is issued, so notice has to be given at least 29 days before the ceremony — in practice, give it with months to spare. You cannot give notice more than twelve months ahead. If either of you is subject to immigration control the waiting period can be extended to 70 days, so go earlier still. Scotland and Northern Ireland run on different systems, with notice going to the registrar for the district where the wedding itself takes place.
Take that as a map rather than legal advice: ring your register office, tell them your date and your circumstances, and ask what to bring and what it costs. Documents, fees and waiting times vary, and theirs is the only answer that counts.
Invitations six to eight weeks ahead is plenty when guests already know the date; go earlier if a lot of people are travelling. Set the RSVP date about a month before your caterer needs final numbers, because you will be chasing stragglers past it either way.
The last month
Final numbers to the caterer, dietary requirements collected in one place, seating plan, running order sent to every supplier, outstanding balances paid, and a rehearsal if your ceremony has moving parts. Decide who is holding the rings, who is making sure the readers know they are reading, and who is answering their phone on the morning so it is not you.
Write one page: timings, supplier names, mobile numbers. Give it to whoever is running the day. That single sheet does more work than any amount of earlier worrying.
What people fret about far too early
Favours. Table names. The playlist. Signage. Confetti. First dance lessons. The seating plan, which cannot be done until the RSVPs are in and will be redone twice anyway. Readings and speeches, which are better written close to the day when you know what you want to say. None of it will be unavailable in month three.
What genuinely cannot wait
Venue and date. Registrar or vicar. The one or two suppliers you would be upset to lose. Notice given in good time. Everything else has more slack in it than it feels like at eleven o'clock at night.
If you have less than twelve months
Most of this still works, compressed. The two levers are the day and the season: a Friday, a Sunday, or a date outside high summer frees up venues and suppliers who look fully booked on paper. Shorten the front end, keep the legal timings exactly as they are, and drop anything from the fretting list without guilt.
Wherever you keep all this — a notebook, a shared spreadsheet, or something like PlanHitch — the useful part is that both of you see the same version, and that what is decided stays separate from what you are still thinking about.
