I'm not sure what you mean. ECS cardholders are not members of the JIB - JIB members are firms who have joined the JIB. JIB cards are available regardless of whether the applicant works for a JIB member company or not.Ok, I see now.

We also have Electricians who have JIB/ECS cards who are not members of the JIB.
This is aimed at those who have the card because they require the ECS but are not members
