ECS is no longer a member of INNSA.

ECS has elected not to apply to subscribe to the Invasives Code of Practice and accordingly has ceased to be a member of INNSA. The terms of INNSA membership require that all members must subscribe to the Invasives Code to provide protection to consumers and the property professionals that serve them. The Code also requires that the demanding technical standards for INNSA membership which include membership of the Amenity Assured Scheme are met at all times.
