But I feel fairly confident that there are UK-localized versions of each.

That does not follow. 18 people make many carrying jobs easier, but they are not necessarily all required.
However, since the four tabletop planks are not joined into a single piece, it is clear that 12 people on a side is not a reasonable approach.
If the tabletop is removed from the support structure, then 12 people make multiple trips with each plank, at 65 lbs per person, per plank.
If the tabletop is not removed from the support structure, and we conservatively estimate legs etc at 50% of the tabletop weight, for a total weight just about 2.3 (US/short) tons ... you would need 66 people, properly distributed, to stay within the OSHA recommended lifting maximum of 70 lbs each.
To get 66 people around that table, they would need to be about 3 feet apart, which is just barely adequate working space.
Fortunately we don't move things like this using people. Not even in the UK!
