MK 10-Way High Integrity Consumer Unit
MK means quality
CU change with limited space hence picked this unit which is narrower than standard split load boxes. Build quality of this unit was of the normal high standard I have come to expect of MK. Worth paying the few extra quid that it costs compared to competitors products. 32A RCBO would be more useful than the 40A RCBO supplied.

Good narrow fit. However although this has internal space for 10 ways, the busbar only covers 9 ways when used as High Integrity (have to add a strap for final position). Front screws a bit fiddly when refitting cover. No blanks included if used as an 8-way (RHS has 2 ways blanked by cover to be cut-out if required). Pity Screwfix don't offer a choice of RCBOs (eg 32amp instead of 40amp, not everyone wants a shower.).

Great for small spaces
Installed a couple of these now both jobs where to replace an old Wylex standard unit and space was tight so a normal 10 way 17th dual RCD would be too big.
Excellent quality plenty of space to dress cables inside the unit even with the RCBOs in there.
Only snag is the front cover can be a pain to refit if the back of unit is mounted on an uneven surface.

MK are a trade byword for build quality, and this unit has never let me down. It is solid and clean in its layout, easy to work with, and presents a great impression to the householder. Functionally, it is a better answer to the current regs than a fully-populated split load unit featuring 2 RCDs - greater integrity of the system can be guaranteed by use of additional numbers of channels controlled by individual RCBOs on the side not routed through the single RCD. (For the non-specialist, RCBOs combine earth leakage and overcurrent protection in a single 'fuse', which means less chance of a fault on one channel taking out half the board's load.) The less problematic channels are fine on the MCBs grouped under the board's single RCD.
One snag: if you plan to use the full capacity of the board's stated architecture, be aware that the busbar supplied is one tang too short to cut into the required two sections. It is shorter than the illustration on the accompanying instructions - d'oh!
