Your electrician should produce a Building Regulations Certificate of Compliance.You get an EICR from the sparky and that is it. He does not register anything with building control. IE. If you are making a house extension that and have had electrics done, YOU need to provide the EICR certificate to building control.
Via their registered body (NICEIC, Napit, etc) they will produce the certificate which then gets lodged directly with building control at the council - and will then show up on searches - particularly important when you come to sell your house.
