In 2017, Individual membership of the association increased by 97 (4.5%) to a total of 2,229 members, Utility Corporate Members remained steady at 66 organisations and Corporate Member numbers increased by 16 (3.8%) to 435.

The Associate Corporate member numbers reduced by 84 (6.1%) to 1,301 predominately due to the enforcement of the constituted maximum number of 10 individual nominees in this category for each Corporate Member. As Associate Corporate members receive limited benefits, there is an opportunity for them to become Individual members in the future, allowing them to access the full benefits of membership.

The overall result is that the Association’s total membership at the end of 2017 is 4,031, a 0.7% increase across all categories.
