Hi, I have a workshop in my garden which I constructed myself within which I use the occasional power tool. Inside I have a ring main serving a number of 13A sockets, I also have a separate lighting circuit for the lights. Both are connected via a RCCB inside a 2 circuit "shed" consumer unit. This then goes via SWA cable to the house. I fitted and wired all these myself in accordance to BS 7671:2008 +A1:2011. I am not a qualified electrician but consider myself to be reasonably competent and know my way around BS standards. The house has a 13A socket inside a weatherproof box and located in a very sheltered position. I have two questions and would appreciate some guidance from some experts in this field please: I know the "correct" way of finishing off the installation would be either to go direct to the consumer unit of the house and create a new circuit or to replace the socket on the side of the house with a fused spur and connect the SWA to that.... but... Q1. If I fit a 13A plug on the end of the SWA and plug it into the socket, does the workshop require any building regs notification and/or control? (in theory) Q2. If I abandoned the fixed wiring I had inside my workshop and simply ran some cheapo (but CE marked) long extension lead with lots of sockets on it, and plugged it into the 13A socket on the side of my house, does this require any building regs notification and/or control? And finally perhaps a provocative question, which would be safer?
