Hi all recently had smart meters fit, after the installation the technician couldn't get the sockets to turn on they just kept tripping. Turns out all the sockets in the house are on one RCD which I believe that's a problem in its self. But after 43 hours of no sockets in the house not working my land lord finally came with an electrician so he says, just found out he fits stair lifts and he admitted he only had his 16th edition. He's changed an RCD and removed wiring for a single plug socket in the dining room which he says was tripping the switch. My questions are should all my sockets in the house run into a single RCD and 2 is some one with a 16th edition even allowed to carry out these works?
Thanks
