Start by agreeing your budget, guest list, preferred date and venue, then book key suppliers such as the ceremony venue, registrar or celebrant, photographer and caterer. Check the legal requirements for your part of the UK early: in England and Wales, couples generally need to give notice at their local register office, while Scotland and Northern Ireland have different processes. Keep track of deposits, contracts, cancellation terms and payment dates, and consider wedding insurance where suitable. Use the relevant GOV.UK or devolved government guidance, and seek professional advice if your arrangements involve complex finances, property or immigration issues.
