Planning a wedding in Cardiff
Book the venue first, then ring Cardiff Register Office on 029 2087 1680 to confirm two registrars are free for that date and time — an approved-venue booking also carries a non-refundable registrar deposit. Legal notice is a separate appointment at your own local register office, at least 29 days before the ceremony (71 if either of you is a non-EEA national), and the office advises giving it around six months ahead. One local quirk worth checking before you set a date: on Principality Stadium event days the streets around Westgate Street close to traffic and city-centre hotel rooms are booked out months in advance, which matters for a Six Nations Saturday.
- When to marry — April to July is the driest stretch in Cardiff, with roughly 72–84mm of rain a month against 130–140mm from October to December — and note that August, at 105mm, is measurably wetter than June or July, so the classic peak month is not the safest bet.
- What it costs — Registrar fees at the council's own rooms are modest and published — £74.50 for a two-witness ceremony at the Register Office, £345 to £550 for the Cedar or Walnut Room at Insole Court depending on the day — but a full venue day is the real number, starting near £800 plus VAT for exclusive hire of St Fagans Castle and £3,900 plus VAT for the Grand Hall at National Museum Cardiff, before any catering.
Once the venue is settled, the next thing most couples deal with is telling everyone. A digital wedding invitation carries the address, a map, your timings and a live RSVP on one link — which matters more than usual when guests are travelling to Cardiff and need directions, and plenty of notice.
