Trailer registration plates.

I read somwhere the UK was bringing in number plates for trailers,similar to our continental cousins,due to trailers going missing,and tracilbilty.Most Eu operators only have the trailer reg on the rear of the vehicle.Would the trailer be registered with DVLC?Due to drivers staying with the same truck,with EU operators,they have for years mastered the art of culinary skills by means of trailer side boxes,stowed with fridges and cookers,due to trailer changing,in the UK,will there be leglisation of some sort,like in Scandinavian countries,they have laws of some sort,that the employer must provide a coffee making machine,etc.Germany,a working night heater.
