What to Book First for a Wedding

The question isn't really "what needs booking?" — it's "what will disappear if I wait?" Almost every wedding planning mistake in the UK comes down to booking things in the wrong order: locking in a venue before the guest list is settled, or falling for a florist before checking the photographer's diary. Get the sequence right and the rest of planning becomes far more straightforward. Here's the actual order, and why each step has to come when it does.

The rule that decides the order: scarcity, not preference

Some wedding suppliers can only work one wedding a day. A venue can only host one ceremony on a given Saturday. A registrar can only officiate one wedding in a given slot. A photographer can only shoot one wedding at a time. These are the things to book first, because if you wait, someone else takes your date — not because they're more important than your florist or your cake.

Suppliers who can serve multiple weddings across a weekend — florists, cake makers, hair and make-up artists working a rota — have more give in their diaries. That doesn't make them less important to your day, just less urgent to book immediately.

The order, in practice

1. Your budget and guest count (before any booking at all)

This isn't a "booking," but it has to come first because it decides everything downstream. Agree your total budget and a realistic headcount with your partner before you contact a single supplier. A venue that's perfect for 150 guests will feel wrong for 60, and per-head catering costs mean your guest count directly sets your venue budget. Skipping this step is the single most common reason couples end up back at square one halfway through planning.

The UK's two main wedding industry surveys currently put the average cost of a wedding day at around £20,600–£22,000, excluding the ring and honeymoon (Bridebook's 2026 report: £20,604; Hitched's 2026 report: £21,990). If you want to see how a given budget splits across categories before you commit to anything, Wedvisa's free wedding budget calculator does this in a couple of minutes.

2. Your venue and date

Once budget and headcount are agreed, book the venue. This is the single most consequential booking of the whole process, because everything else — suppliers, paperwork, even your own annual leave — gets planned around it. High-demand UK venues, particularly for peak summer Saturdays, often book out 12–18 months ahead. Season and region both move price significantly: peak season (roughly May–September) and summer Saturdays cost the most, while January, February and October tend to be considerably cheaper, and London consistently runs above the national average compared with Scotland, Wales or the North.

3. Your registrar or celebrant

The moment your venue and date are confirmed, check availability with your local register office or your chosen celebrant. This has to happen early because registrars, like venues, can only cover one ceremony per slot — a civil booking can't actually go ahead if the local registration service doesn't have the capacity to attend at your chosen time. This is also the point to start the legal paperwork clock:

• In England, Wales and Scotland, you must give notice at least 29 days before the ceremony, per GOV.UK's guidance and mygov.scot's guidance — though most registrars recommend doing it 10–12 weeks out for a buffer.
• In Northern Ireland, the minimum is 28 days, per nidirect's guidance.
• Fees run £46.50 per person in England and Wales (£63 if either of you is subject to immigration control), or £22 per person in Northern Ireland.

If you want a humanist ceremony, note that it's only legally binding in Scotland — around 30% of Scottish marriages are now humanist. Elsewhere, you'll need a separate registry ceremony alongside it.

4. Your photographer and videographer

These are the classic "once-a-day" suppliers, and the best in any area are frequently booked 12 months or more ahead — often before some couples have even finished choosing a venue. Book these as soon as your date is locked in, not after you've sorted flowers or stationery. Unlike almost everything else on this list, there's no "catching up later" if your favourite photographer is already booked for your date.

5. Your caterer and band or DJ (if not included with the venue)

If your venue is dry-hire, the caterer needs booking next, along with your band or DJ if you want live entertainment. These typically need 9–12 months' notice for a popular date, since good ones do get booked across a season but have less flexibility than florists or cake makers.

6. Florist, hair and make-up, and everyone else with more flexibility

Florists can generally be booked 6–12 months out (stretching to 12–18 months for larger, design-led arrangements), since many can serve multiple events across a weekend. Hair and make-up artists are in high demand but can usually be secured with 6–9 months' notice, with a trial 4–8 weeks before the day. This is also a sensible time to start dress and suit shopping — gowns in particular can take several months to order and alter.

What genuinely doesn't need booking first

It's easy to feel like everything is urgent once you start planning, but a few things can comfortably wait:

• Stationery — invitations don't need to go out until 4–8 months before the day.
• Wedding insurance — worth taking out once your first non-refundable deposits are paid, not before.
• Favours, table decor, and small details — these can wait until the final few months without any risk.
• Cake tastings — most cake makers can accommodate bookings much closer to the day than photographers or venues can.

Spending early energy on these before the once-a-day suppliers are locked in is a common way couples end up scrambling later.

Mistakes that come from booking out of order

• Booking a venue before agreeing the guest list, leaving a space that's the wrong size either way.
• Falling for a florist or cake maker before checking the photographer's availability — by the time couples think to check, the best photographers for their date are already gone.
• Booking a venue without confirming registrar availability at the same time, which can mean a beautiful venue with no way to legally marry there on the day you want.
• Leaving legal notice until the final weeks, when the 29-day (or 28-day) minimum leaves no room for any paperwork issues to be sorted.
• Assuming all suppliers have the same lead times. A florist and a photographer are not remotely comparable in how far ahead they need booking — treating them the same is how couples end up rushing the wrong one.

Frequently Asked Questions

What should I book first for a UK wedding? 

Settle your budget and guest count first, then book your venue and date, followed immediately by your registrar or celebrant and your photographer/videographer. These are the "once-a-day" bookings that can't be rearranged if you wait.

Why do venues and photographers need booking so far in advance? 

Because they can each only serve one wedding per day. Once a date is taken, it's taken — unlike florists or cake makers, who can often work multiple events across a single weekend.

Should I book the venue before the guest list is finalised? 

No. Guest count directly affects which venues are realistic and how much per-head catering will cost, so it should be settled first, even roughly.

How far in advance should I book my photographer? 

Ideally as soon as your venue and date are confirmed — the best photographers in any area are often booked 12 months or more ahead of the wedding.

When should I start the legal paperwork for a UK wedding? 

As soon as your venue and date are locked in. The legal minimum is 29 days' notice in England, Wales and Scotland (28 in Northern Ireland), but most registrars recommend giving notice 10–12 weeks out to leave a buffer.

What can I leave until later in the planning process? 

Stationery, wedding insurance, table decor and favours, and cake tastings all have far more flexibility than venue, registrar, and photography bookings, and can comfortably wait until closer to the day.

Do florists and cake makers need booking as early as photographers? 

No — most can serve multiple weddings across a weekend, so 6–12 months' notice is usually enough, compared with 12+ months for photographers and venues.
