Hi. I'm new on here. I'm not an electrician. I'm just seeking some advice. I hope this is the correct section. My parents have just had a new consumer unit fitted. The electrician is NAPIT registered. He didn't leave an installation certificate. When I phoned him and asked about this he explained that it's all submitted online these days, just like gas safe certification. Is this correct? Or should I demand an actual physical copy? Many thanks.
