Start by setting your budget, preferred date and guest list, then book a licensed ceremony venue or contact your local register office. Check the official GOV.UK guidance for the documents and notice period required in your part of the UK; notice is usually at least 28 days, but it can take longer in some circumstances. Add key bookings such as the celebrant, venue, photographer, caterer, transport and insurance, and keep written confirmation of costs and cancellation terms. Before and after the wedding, update relevant records, beneficiaries and financial providers, and consider speaking to a solicitor about wills and any estate-planning changes.
