Category C1+E
You can drive C1 category vehicles with a trailer over 750kg, but the trailer - when fully loaded - can’t weigh more than the vehicle.
The combined weight of both can’t exceed 12,000kg.
So you can tow 6t with a 7.5t lorry provided the lorry is loaded up to 6t I assume.
But, as Erbas pointed out, there is a further restriction on those of us (wrinkly or smooth) who got C1+E entitlement simply by passing a standard driving test before 1/1/97. We are restricted to a total train weight of 8,250kg so the best we can do is a 4,125kg trailer and a 4,125kg tow vehicle. That might, just, allow a Centaur.
