I am filling out all the relavant forms for our sale. It asked about electical work and to provide BS7671 certificate. We have refurbished most of the house, most recently the kitchen but I can only find one certificate. It's for the electric shower in 2014. Is this enough to show the electrics are good or does this only cover the shower??? I know I didn't get a certificate from the electrician who did the kitchen 😣
