Membership of ERNLLCA is open to all parish councils, town councils and parish meetings within the East Riding of Yorkshire, North Lincolnshire and North East Lincolnshire. Presently, there are no parish or town councils in the City of Hull.
The cost of membership of ERNLLCA is two-fold, part of the fee is forwarded directly to NALC to fund the central corporate services (such as the Legal Services Team) and the remainder is retained to cover the cost of the local Association. The membership fee is paid annually and covers the period from 1st April to 31st March. Fees are based on the level of electorate in the parish and any council that is interested in taking out membership can be provided with an individual quotation. Councils joining ERNLLCA for the first time part-way through the year may qualify for a pro-rata subscription.
