I have employed a building contractor to construct a dormer bungalow on my behalf. This is now approaching completion. During the construction I employed the services of an engineer to provide detail to the builder as to the levels of insulation required (aiming for a B1 cert). All this has been completed. I have heard that it is the builders obligation to provide me with a BER Cert on completion of the house. I'm just wondering if this is true or whether it is my own responsibility to get this. There is nothing in the tender contract about the BER.
