Burial authorities have rules and regulations setting out what you can or cannot have in their cemeteries. The regulations restrict the size, shape and material of memorial you are allowed to have and can prevent or require the use of some ornamentation. Some of these rules may seem petty and unreasonable but burial authorities apply them so that there is an element of conformity throughout the cemetery.
All memorials must be fixed according to nationally agreed standards, installations must be carried out by suitably qualified masons.
