Nice to see pedantry being demonstrated at it's finest! I think the difference is purely semantic, but as a rule 'Consumer Unit' is language is use with domestic customers, other than that it's Distribution Board.
The regulations make a distinction between the two along with all manufacturers. I think it's a bit more than just semantics.
The original 'consumer unit' was specific to domestic single phase installations and incorporated the cutout, metering, main switch and circuit protective devices into a single unit. This was in the 1950s.
What I can't find is a more up to date definition, other than the one in bs7671 which is not overly specific

IMO it seems like all CUs are DBs, but not all DBs are CUs...
That's what I said earlier, and is in the definition in bs7671, CUs are a particular type of DB which has passed specific type testing and has a DP main switch and a few other things
then what you are refering to is a mainboard or switchgear [emoji12]That's what I said earlier, and is in the definition in bs7671, CUs are a particular type of DB which has passed specific type testing and has a DP main switch and a few other things

here you go, acti9 wall mounted switchgearNope, switchgear has it's own definition and would normally encompass DBs, switch fuses, fused switches, busbar chambers etc etc.
Mainboard is not a defined term as far as I know, and not one that I think I have ever heard of before.
