What is the etiquette for guests attending a same-sex wedding?

Short answer

Treat a same-sex wedding the same as any other wedding. Be kind, follow the dress code, and use the names and titles your hosts have asked you to use.

Your main job is to celebrate the couple. Arrive on time, dress as the invitation asks, and bring a gift or card if you wish. There is no special rule for same-sex weddings beyond the usual courtesies.

Use the names and titles your hosts have chosen. If the invitation does not say, ask quietly or check the wedding website. Do not assume roles such as bride or groom unless you are sure they fit. If you are unsure about a term, it is fine to ask the couple or their wedding party in advance.

RSVP by the date given so the couple can plan seating and meals
bring a plus-one only if your invitation says you may
keep photos respectful and follow any request not to post them
share any cultural or family traditions you bring with care and consent

Dance, toast and enjoy the day. If you are part of the wedding party, follow the couple's guidance on tasks and timing. For legal or religious details about the ceremony, check GOV.UK, the register office or your place of worship, as rules can vary.
