Start with your budget, guest list, preferred date and venue, then book the ceremony and key suppliers such as catering, photography and music. Contact your local register office about giving notice and check which documents you need; notice periods and rules can differ across the UK, and some couples may need to give notice earlier. Arrange wedding insurance, accommodation and transport, and confirm timings and payments with each supplier. Before the day, check whether you need to update your name, address or benefits, and keep copies of important documents and bookings.
