I emailed Ohme the photo of the installed KerboCharge gully and what the HA had requested and got a reply back from them this afternoon,
“I have requested for an installer to be assigned to pass over the relevant information to you. I will send over the required documents once in hand.
Best Wishes,

So it looks like things are hopefully going ahead.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
