No, a religious funeral service is not necessary, and there are a variety of alternatives. Maybe a relative or friend may be willing to take the service if they believe they can. Many congregation members are permitted to speak or read verses or poems.
The British Humanist Association, Institute of Civil Funerals and Qualified Celebrants Fellowship have networks of officers who can deliver a very personal, non-religious ceremony.
Check for more information from us or visit humanist.org.uk or iocf.org.uk to arrange a humanist ceremony. It is important to note that a humanist ceremony is not the same as a non-religious ceremony.
