Imagine this: you’re standing at the altar, the sun is shining, your loved ones are smiling, and every detail is perfect, just as you pictured it. Imagine getting to that moment without stress, panic, or forgotten tasks. That’s what a wedding planning checklist does for you—it’s like a roadmap to your dream day. Weddings are exciting, but they come with many little jobs, from picking flowers to booking a band. Without a plan, it’s easy to miss something big, like forgetting to order your cake or sending invitations too late.
This wedding planning checklist is your secret weapon, keeping you organised and calm, whether you are planning a huge party or a quiet gathering. It works for any wedding, anywhere—though we’ve sprinkled in some UK-specific tips since that’s where many of our readers are!
Why You Need a Wedding Planning Checklist
A wedding planning checklist is like a best friend who keeps you organised. It lists all your tasks, from picking a date to sending thank-you notes. Without one, you might forget something important, like booking a photographer or getting a marriage license. Our wedding planning checklist is easy to follow and works for any wedding, big or small, in the UK or beyond
Why a Wedding Planning Checklist Is a Must-Have
Let’s be real—planning a wedding is a big deal. There are many things to consider: venues, dresses, food, music, and more. A wedding planning checklist breaks it down into simple steps to avoid feeling lost or overwhelmed. It’s like having a guide who says, “Hey, do this now, and you’ll be fine later.” Without one, you might forget to book a photographer until it’s too late or realise the day before that you don’t have a marriage license.
Yikes! This wedding planning checklist is flexible—you can tweak it for a fancy castle wedding or a cosy backyard bash. It’s all about making the process fun and stress-free so you can focus on the joy of marrying your favourite person.
12+ Months Before: Dream Big and Get Started
This is the time to imagine your perfect wedding. Here’s what to do first:
- Set Your Budget: Decide how much money you can spend. Recent surveys suggest the average UK wedding costs around £25,000 in 2025. Use Promesse’s budget tracker to plan your spending.
- Choose a Date: Pick a date that suits you. August is the most popular month in the UK because of warm weather and school holidays, but off-peak months like April can save money.
- Make a Guest List: Write down who you want to invite. Start with close family and friends, then add more if your budget allows.
- Pick Your Style: Consider your wedding vibe—maybe a fancy castle or a cosy barn. Check out Promesse’s Inspiration Hub for ideas.
- Book Big Vendors: Promesse’s vendor marketplace makes finding a venue and key vendors, such as a caterer or photographer, easy.
Tip: If you have less than a year, don’t worry! Focus on booking your venue and key vendors, as they get booked quickly.
9–12 Months Before: Lock in the Big Stuff
Now it’s time to nail down major details:
- Hire Key Vendors: Book a photographer, caterer, band or DJ.
- Shop for Outfits: Look for your dress or suit. Give yourself time for fittings to make sure it’s perfect.
- Send Save-the-Dates: Let guests know your date early, especially if they’re travelling.
- Plan Your Honeymoon: Think about where you want to go after the wedding. Booking early can get you better deals.
Avoid This Mistake: Don’t wait too long to book vendors, especially in peak months like August, when top vendors are in high demand.
6–9 Months Before: Add Personal Touches
Your wedding is starting to take shape. Here’s what to do next:
- Choose Your Wedding Party: Ask friends or family to be bridesmaids, groomsmen, or other memorable roles.
- Order Invitations: Pick invitations that match your style.
- Book Smaller Vendors: Hire a florist, cake baker, or hair and makeup artist. Check their portfolios for quality.
- Plan Fun Events: Think about a hen do, stag party, or rehearsal dinner.
Tip: Personalise your wedding with unique touches, like custom invitations or a special song for your first dance.
4–6 Months Before: Focus on Details
You’re halfway there! Focus on these tasks:
- Plan the Menu: Work with your caterer to choose food everyone will love. Include options for guests with allergies.
- Buy Rings: Pick out your wedding bands. Make sure they fit comfortably.
- Book Transport: Arrange cars or other transport to get to your venue. A vintage car can add a fun touch!
- Check Your Outfit: Have a fitting to ensure your dress or suit is perfect.
Avoid This Mistake: Don’t forget to read vendor contracts carefully to avoid surprises like hidden fees.
2–4 Months Before: Get Everything Ready
Things are getting exciting! Here’s your to-do list:
- Send Invitations: Mail or email your invites. Ask guests to RSVP so you know who’s coming.
- Plan the Ceremony: Work with your officiant to decide what you’ll say or do during the ceremony.
- Buy Gifts: Get small thank-you gifts for your wedding party or parents.
- Make a Timeline: Plan the day’s schedule, such as when the ceremony starts or when you cut the cake.
1 Month Before: Almost There!
You’re so close to your big day! Here’s what to do:
- Confirm with Vendors: Call or email all vendors to double-check details.
- Get Your Marriage License: In the UK, you must give notice at least 28 days before your wedding (GOV.UK Marriage). Visit your local register office.
- Have a Final Fitting: Try on your outfit one last time to ensure it fits perfectly.
- Take Care of Yourself: Planning can be stressful, so take breaks and get plenty of rest.
- UK Tip: Ensure you understand your marriage license’s legal requirements to avoid last-minute issues.
1 Week Before: Final Touches
It’s almost time! Here’s what to do:
- Pack for the Day: Pack a bag with essentials like makeup, extra shoes, or a phone charger.
- Share the Schedule: Give your timeline to vendors like the photographer and caterer.
- Practice Your Vows: If you wrote your vows, practice saying them out loud.
- Relax: Spend time with your partner or friends to stay calm and happy.
Avoid This Mistake: Don’t try to do everything yourself—delegate tasks to your wedding party or planner.
The Big Day: Enjoy Every Moment!
You did it! Here’s how to make your wedding day unforgettable:
- Eat Breakfast: Start with a good meal to keep your energy up.
- Follow the Timeline: Trust your schedule and let vendors handle the details.
- Have Fun: Smile, dance, and enjoy your special day with loved ones!
