This is the basic list in every parish of all those entitled to vote on elections within the Church of England. Those entitled to have their names on this roll have to be 16 years of age or more and they must reside in the relevant parish or be regular worshippers in the church whose roll they wish to join. The roll is completely renewed every six years, at which point all members have to re-apply for membership or else their names will be deleted. By this means, the continuing validity of the roll is maintained.
