Trust Mark logo - cyb - japanese knotweed removal uk


Trust Mark is a quality mark which operates a framework under which 30 plus scheme operators work in the RMI (repair, maintenance and improvement) sector, including trade associations, local government trading standards teams, and independent scheme operators.  We are full members as part of our PCA membership.

Although we note our competitors are generally members of Safe Contractor, Chas, Exor, Construction Line and the like, these accreditations may be simply obtained by an effortless application and annual membership fee.  Being brutally honest we do not see the point and believe that our RICS, PCA, ISO 9001 and ISO 14001 memberships/accreditations supersede all of these accreditations resulting in a more cost effective end product to our clients.
