How to Address Wedding Invitations in the UK: Full Guide

In the UK, the outer envelope is the formal one. Write the guest's full name and address on the front, with their title if you know it. Use "Mr and Mrs James Smith" for a married couple with the same surname, or "Mr James Smith and Mrs Jane Smith" if they prefer separate titles.

For unmarried couples living together, write both names on one line or two lines: "Mr James Smith and Ms Jane Jones". If they live apart, send separate invitations to each address. Always use the guest's preferred title, whether that is Mr, Mrs, Ms, Miss, Dr, Rev, or no title at all if they have told you so.

For a family with children, write the parents' names on the outer envelope and list the children's first names underneath. For example: "Mr and Mrs James Smith" on the first line, then "Oliver, Emily and Harry" on the second line. This tells the family exactly who is invited.

If the children are over 18, they should receive their own invitation, even if they live at home. For younger children, you can write "and family" after the parents' names, but naming them is clearer. If you are only inviting the parents, write just their names, and do not add "and family".

When parents have different surnames, write each parent's full name on separate lines. For example: "Ms Jane Jones" on the first line, "Mr James Smith" on the second line, then the children's names underneath. This keeps the invitation clear and respectful.

If the children have a different surname from one parent, include their surname on their line, for example "Oliver Smith and Emily Smith". If the children are adults, give them their own invitation. For blended families, list everyone by their preferred name and surname, and do not assume anyone has changed their name.

Many UK couples skip the inner envelope and use just one outer envelope. In that case, write the full names of everyone invited on the front. For a couple, write both names. For a family, write the parents' names and the children's first names, as described above.

If you are using a single envelope, you do not need to write "and guest" on the front. Instead, write the guest's name and add "and guest" on the same line or below, for example "Mr James Smith and guest". This is the clearest way to show that a plus one is welcome. If you are not offering a plus one, write only the named guest's name.

Yes, write "and guest" on the envelope when you are inviting someone with a partner you do not know by name. Put it on the same line as their name: "Ms Jane Jones and guest". This is standard UK etiquette for a plus one.

If you do know the partner's name, always write it instead of "and guest". It feels more personal and avoids confusion. If you are not offering a plus one, do not write anything extra. Only named people on the envelope are invited, so be careful with wording on the invitation itself if you want to avoid children or extra guests.

Send your invitations 6 to 8 weeks before the wedding. This gives guests time to reply, book travel and arrange time off. For a wedding during a holiday period or with many guests travelling from abroad, send them 10 to 12 weeks ahead.

You must also consider your venue and registrar deadlines. You give notice at least 28 days before the ceremony in England and Wales, and at least 29 days in Scotland. In Northern Ireland it is 28 days. Your invitations should go out after you have confirmed the venue and the date, but before your own final numbers are due to the caterer.

Weigh your fully assembled invitation, including the outer envelope, any inner envelope, RSVP card and reply envelope. Standard UK stamps cover a regular letter, but wedding invitations are often heavier or thicker. Take one finished invitation to the Post Office and ask them to check the weight and size.

Use the correct stamp for the weight, and add extra stamps if needed. If you are sending invitations abroad, use international stamps or ask at the Post Office for the right postage. You can also hand-deliver invitations to local guests, but still use a stamp if you want a postmark. Always post well before your RSVP date, and keep a few spare invitations in case you need to send a second round.
