Does a Church of England funeral have to have a commendation?

If the Common Worship funeral service is used, the service must include a prayer of entrusting or commending the departed to God’s mercy: the commendation is not an optional part of the service.  The Series One burial service provides the option of including words of commendation in the prayer of committal.  There is no explicit commendation in the burial service in the Book of Common Prayer.
