Following installation of home charger unit at my home, BP Chargemaster failed to send me: (i) NICEIC domestic electrical installation certificate; and (ii) NICEIC Buildings Regulations Certificate of Compliance. I had to raise complaints with the customer support team - who didn't understand the request and promised the appropriate person would contact me. They never contacted me as promised. I am still waiting to receive: (a) copy of completed QA Checklist form for installation works; and (b) copy of the completed Installation and Functional Test Report for installation works. I have requested these by email and calls to BP Chargemaster's customer support - no response and the documents are not being supplied. Order 102110 and INV 102110300
