Good communication initially with the team. Left an email after installation but no reply. I thought the homecharger was like a plug witch last a lifetime. Now found out they go wrong and BP chargmaster get poor ratings a on the comparison website I saw so feel apprehensive. Can't easily find out how to register and am looking on FAQ right now. We dug as 60cm trench to a post and armoured cable not used which was a surprise but I guess that's ok as we have the certificate. Slightly concerned so we put rigid warning board on top before filling trench. Engineer did neat work and easy to work with. Aga helpful and knowledgeable.
