Personally, when moving a CU I use crimps and SA tape, that way the cables can be buried in the wall (providing they're in a safe zone). Then again, it all depends on where the existing CU is and where it's moving too. If all the cables are surface mounted then I'll use a DIN rail box.

I had a job a while back where I had to change and move a CU due to moisture problems causing a fire within the existing CU. The cables were all behind stud wall so when moving the CU, I used crimps and SA tape to allow them to be run behind and along the wall then I used a nice piece of 3mm sheet metal to protect the cables that ran through 'non' safe zones.
 
Why not do away with all the connections altogether. For example, for a ring main in the old CU traced back to the first two sockets and connect them up to each other, then break into that circuit from the new CU. A lighting circuit feed would be removed from the old CU and a new feed put in from the new CU. I understand it may be more work, or would it if the new extension causes floorboards to be lifted. Certainly removes unnecessary conections/jointboxes in a bathroom?
