I've done a inspection & test on a property that is rented. The installation has failed on numerous issues, so want to get the conditioning report done asap. Report all done, except for Landlord's name and address. So, we're working for a maintenance company, they're working for the letting agent, on behalf of the landlord. The letting agent won't give us the landlord details because the landlord doesn't want them to. Now, under Part P, I'm under the impression you have to supply both owner and occupier details when notifying. But this is a conditions report, an unsatisfactory one at that. There are no 1's, so it's not dangerous, just a few 2's and lots of 3's. Do I issue the certificate without details? I have done a Land Registry search on the property, so do have the property owners details. Any comments and suggestions please.
