I am referring to installing a new recessed consumer unit eg like the Hager one we were looking at Elex.It doesn't, but you will need to be sure that the new OCPDs or RCBOs meet the requirements of BS EN 61439-3, or even a product recall, failure to do so could result in a F1 or even a C1 or C2 on any future EICRs
