WEDDING CEREMONIES AND RECEPTIONS There is no numerical limit for indoor or outdoor gatherings, including wedding receptions and ceremonies. There will be no limit to the number of people allowed to attend weddings, civil unions and receptions in England starting July 19.It doesn't seem likely that weddings can be held abroad this summer. For the time being, international travel is banned in the UK until 30 June, unless you have a “reasonable excuse”. Otherwise, you risk a £5,000 fine if you leave the country.
After June, things may relax, but it seems unlikely that overseas weddings will be able to continue for a while yet.
