but that wouldn't look great and my wife wouldn't be happy, is there a better option?
hi . i know this is of no help but it would be your cheapest option, other than put the tails in the cavity or board it over and forget it..
if it was me i would ring the niceic or the eca and get them to come and look at the job, assuming the contractor that did the job is a member of one of these organisations..
Rang niceic and they will only get involved when Taylor Wimpey have agreed as they are the ultimate contractor of the sparky.
Tails in the cavity would be ideal but apparently that's a no no according to the installers yesterday, although I swear I read somewhere recently that they can be if in conduit....anyone please confirm?
If not, then the only option is as per RF's idea and running the tails externally and up into the floor space before into the CU. As in this pic-
