A marriage can take place in:
a Register Office
a church of the Church of England, Church in Wales, Church of Ireland, Presbyterian or Roman Catholic Church in N. Ireland
a synagogue or any other private place if both partners are Jewish
a Meeting House if one or both partners are either members of the Society of Friends or are associated with the Society by attending meetings
any other religious building provided that the person marrying the couple is registered by the Registrar General
premises approved by the local authority - see under Religious marriage ceremonies (England and Wales only)
a place where one partner is seriously ill and not expected to recover
the home of one of the partners if the partner is housebound, for example, has serious disabilities or is agoraphobic
a hospital, if one of the partners is unable to leave or is detained there as a psychiatric inpatient
a prison, if one partner is a prisoner.
Local authority approved premises (England and Wales only)
Local authorities in England and Wales may approve premises other than Register Offices where civil marriages may take place. Applications for approval must be made by the owner or trustee of the building, not the couple.
The premises must be regularly open to members of the public, so private homes are unlikely to be approved, since they are not normally open to the public. Stately homes, hotels and civic buildings are likely to be thought suitable. Approval will not be given for open air venues, such as moonlit beaches or golf courses. Generally, the premises will need to be permanent built structures, although it may be possible for approval to be given to a permanently moored, publicly open boat. Hot air balloons or aeroplanes will not be approved.
If you want to get married in local authority approved premises you should obtain a list of premises from the local town hall. Or you can search for approved premises on the General Register Office's website at: www.gro.gov.uk
