A Celebrant is a person who will create and deliver the funeral ceremony if a religious minister is not required. They are trained professionals with a wealth of experience and will help you achieve the unique and very personal funeral ceremony that you wish for the person who has died.
Celebrants conduct Funeral Ceremonies across the UK and can be found on funeralmap or your funeral director will know which Celebrants operate in your area. They will visit you at home and will ask you a great deal about the life and personality of the person who has died. There are professional associations that Celebrants belong to so do contact them or look at their websites to see lists of qualified members. See What type of funeral ceremony?
It is always difficult at a time when you may be very upset, to remember to ask about how the Celebrant was trained and qualified and what professional associations they belong to, but it is worth enquiring as it is such a very important job you are entrusting them with.
