Client wants to replace their kitchen. The house currently has a 4 way rewireable fuse box (lights, ring, cooker, immersion heater). The customer understands that this needs upgrading and is happy for a CU replacement. However, they are not happy to have a rewire. The general condition of the installation after an initial basic inspection (no proper testing yet) looks good.
So, I could put in a new CU with a new circuit for the kitchen but how would you go about migrating the existing circuits allowing for spliting upstairs/downstairs lights and sockets across RCDs?
Or I could split the supply via henly block and put the kitchen on its own RCD and ignore the existing installation. Perhaps upgrade the rewireable fuses to MCBs as part of it although this would mean making changes to the installation that don't meet current regs.
Or I could put in a CU with 4 RCBOs for the existing circuits and one for the kitchen. All circuits would be protected but there would be no allowance for upstairs/downstairs spliting.
How would you approach this?
