It looks like it is designed to promote the concept of being a professionally registered technician with one of the current registration schemes. The http://www.professional-technician.org.uk/index.php
site includes the statement that:
"An applicant joins a professional body relevant to their area of study or career aspirations. The professional body then assesses underpinning knowledge, competence, and commitment to professional ethics, conduct and CPD. Currently there are three registration categories applicable to technicians, EngTech, RSciTech, and ICTTech."
So it's not really a change from an Engineering perspective, but it does promote both science and engineering technicians for professional registration.
