I have six plastic back boxes mounted an a wooden board which is spaced about 20mm from the wall.

Connections between the boxes will be out of the back, behind the board and back into another box.

Do the wires between the boxes, going behind the board need to be double insulated?

    An outer sheath is there mainly to provide mechanical protection. In its absence, Is the wall rough bare brick/stone or smooth plaster? Are the screws holding the wood to the wall exposed? Could a cable get snagged on one of the screws? Etc.

    The wall is smooth plaster and no screws protrude behind the board.   The cables would not be accessible to a finger but it would be possible to push a hacksaw blade or similar up behind the board a to damage the cable.
