What is it your expecting?
As long as you have the blue benchmark your ok
Surely you know that CORGI have to be notified when a boiler is fitted and they send a blue certificate to the householder?
Or are you another cowboy who fit boilers without notifying CORGI?

Yes i am aware you have to notify!
The OP wanted to know what they had to send to vaillant.
At this point in time we have to assume the installer has notified the right people and all is legit. I believe the installer was refering to registering the appliance with vaiilant for warranty purposes.I asked about the certificates and he said you send the forms back to vallaint and then the certificates come later.
