I have just been messaged on facebook by someone who has had an extension and for one reason or another the spark (probably the builder) has gone AWOL and they cant get the EIC or part p notification. I am advising them that the best they would get now is an EICR unless they can get the original installer back. What do they do about part p or should they just ask building control if they will accept an EICR to sign off the build?
