Iam looking for advise regarding the completion certificate in Scotland. Iam an approved electrician who recently started working for myself and have an up to date SJIB card also recently passed 17th edition and SELECT traing course for testing and inspection. I was been asked by a customer to sign off the electrical test certificate required from building control after recent building alterations she had done (builder had vanished after payment). I did not do any of the electrical work myself but completed a periodic inspection report after a full check off all electrics (all electrical work checked out ok). The form was submitted to the building control who said everything is ok with my completed form but have asked for the certificate to be stamped. This is the first time I have been asked for a stamp and to be honest I dont know what they mean by a stamp. I am going to meet building control at the house on Friday but was wanting to know before I meet them.
