Time to plan
The average time required to organise a personal funeral for a family member, partner or friend, in the United Kingdom was reported in parliament as around 15 days in 2016.
This near two-week period is seen to give the family and friends of the deceased time to make plans while mourning, but not forcing them to live in the shadow of the funeral for too long. The two-week average also allows sufficient time to complete the formal procedures required, including registering the death, contacting a funeral director and arranging the funeral service for an appropriate, and available, time slot.
Although generally there's no time restriction for families and friends to hold funerals for the deceased in the United Kingdom, some religions do have specific time frames within which the funeral should be held. For example, if the deceased is a practising member of the Jewish or Muslim faiths, the funeral service should be held as soon after the death as possible.
Other religious traditions, Catholicism, Protestant faiths, Quakers and Hinduism, don’t require the funeral to take place within any specific space of time.
‘Official’ funerals, held for royalty and other prominent figures are typically held within a week of the dignitary passing. Given the scale of these occasions this seems very quick, but the plans have generally been made far in advance of the death.
