but are looking for somewhere outside if possible.
Hiya, just wanted to say before you went getting your hopes up - if you mean 100% outside, you can not be legally married outside, it needs to be in an approved structure -eg. you can have a garden with a gazebo, but not just a garden
We found this on the citizens advice website:
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.
Regards tonbridge though, you can have ceremony only type affairs in Tonbridge Castle - GORGEOUS venue!
