Just an update. Registration went fine, the inspection / mot involved a quick walk round and aye that's ok.
Only issue was the shipping papers from UK to Cyprus did not have the Trailer serial number on so make sure you check this if ever shipping. As the guy said at the Vehicle Inspection centre how does he know its the same trailer I shipped if no serial / chassis number.
I also in advance bought the Trailer maintenance and spares manuals off Ebay which they photocopied the Trailer specs page.
So now my trailer is registered with its own registration so hopwefully no issues when I head hhrough Europe etc.
