Start by setting a budget, choosing a date and venue, and booking the ceremony, registrar or celebrant, photographer and key suppliers. You’ll also need to give notice of intention to marry at your local register office, usually at least 28 clear days before the ceremony; this can be longer in some circumstances, including certain immigration cases. Allow around 12 to 18 months for a larger wedding, although a smaller ceremony may be arranged in a few months if dates and suppliers are available. Check the latest requirements with your local council or GOV.UK, as rules can vary depending on your circumstances.
