The appropriate use of aircraft type is very sensible and CAP413 already states this:
Section 2. General Phraseology
Aircraft Callsign Prefixes
Where no confusion is likely to occur and the additional information may help the controller or other pilots, the name of the aircraft manufacturer, the aircraft model, or the aircraft category, e.g. 'Helicopter', may be used as a prefix to the registration e.g. 'Harvard G-ABCD'
However, as ever, brevity is of the essence, hence "Cessna G-ABCD" is useful, but "Rheims Cessna F152 Aerobat G-ABCD" may be deemed a little too much info on every call
