Been asked to carry out the electrics in a new build for someone I know. Although I’m a qualified electrician I’m not registered with Select or a similar body, I know it is advised to use someone from one of these bodies to carry out work & sign it off but where would I stand legally if I just sign it off myself? I done a new build a few years back as someone told me local council would accept a test sheet as long as they know you’re an electrician, which they did, no problem. Now I’m a bit older & wiser (possibly) I seem to be a bit more cautious about taking this on!! Would it be allowable for someone from one of these bodies to sign the test certificate off but for me to also sign to say I carried the work out?
