UPDATE.
My neighbour finally got the (NICEIC) certificates and we went in to have a look before the new tennents move in.
Circuit 1 modification
MWC confirming 2G & 1G sockets added to what was the cooker circuit, no comment about changing the MCB to the new 32A RCBO, nor the 2.5mm cable added to the "end" of the old 7/029 cable.
Me thinks the MWC should state that the MCB has been changed to the RCBO
Why has he fitted a 32A breaker to a radial where the last 3-4 meters are 2.5mm cable?
No comment about the JB concealed behind new cupboard
(No comment on the fact that the kitchen fitter did all the install work.)
Circuit 2
Spur off existing 2G socket
RCD test times for 1x and 5x almost identical - which looks unusual.
Neighbour not happy and about to pen a letter to the big shed who they ordered the new kitchen off
