If you have no earth you cannot fit metallic switch plates

If I understand the OP correctly, one of the switches ('Switch 2') has an earthed back box. If that is true, presumably a metal plate dimmer could be installed in that one (although, ideally, one would first confirm that the 'earth' really was an earth)?

Kind Regards, John

SWITCH 1 HAS 4 EARTH CABLES CONNECTED TO A CABLE TERMINAL CAN I RUN A EARTH CABLE FROM THAT TO THE EARTH CONNECTOR IN THE BACK BOX THEN RUN A EARTH FROM THE BACK PLATE TO THE EARTH ON THE BACK OF THE DIMMER SWITCH MANY THANKS

Yes, but you will need to confirm continuity back to the supply earth.
