I need to mount a consumer unit in a wooden workshop. I have been led to believe that you are no longer allowed to mount on to wood? Once again I would appreciate your advice on how or what to use? Thanks Marcus.
Presumably you are using a modern all metal consumer unit?
Assuming this is typical shed construction, it is normal to fit a sheet of plywood or chipboard to the 'uprights' in the shed, and fit the cu to that, to prevent the screws going through to the outside.
With all electrical connections properly terminated and all holes correctly sealed in the cu, there shouldn't be a major issue, unless anyone can see I've missed something.
Nor ne, for what it's worth. The (somewhat controversial) 'Amd3' reguklation merely requires a 'non-combustible' CU, and does not concern itself with what it is attached to..

Indeed. The only thing I would add is that regs, per se, only require 'sealing' to IP4X on the top surface and IP2X elsewhere (i.e. no requirement for protection against water ingress) but, in the case of a shed, I would think one probably ought to address the issue of possible water ingress, particularly on the top surface.
I think it's safe to say that I may have had an unnecessary concern? There is minimal risk from water penetration as the shed is double skinned osb with external timber cladding and a vapour barrier. I will be using a metal-clad CU which I can easily off-set. As ever I do appreciate all your help!

Fair enough. However, assuming the shed is not heated, there is likely to be a risk of at least 'dampness' - so reasonable 'sealing' of the CU (and, as sparkwright says, avoidance of holes in the top of the CU if possible) is probably desirable.
