It's likely that I'll need to find my own independent Heat specialist, as not pleased they (installers, builder and specialist) all converse with one another and suddenly out of nowhere get to no availability.

Or just commission a plumber to do the replumbing?

As soon as you touch it your installer will argue that it voids the warranty and I doubt any third party will warranty a system largely installed by someone else (why would they?).  Therefore if you are going to bypass the LLH you have already accepted the risk of a warranty argument (mad I know).  If you are going to do this you might as well cut to the chase and get a regular plumber to change the pipework.

Sorry I didn't explain the situation fully, the agreement was the work would be done with the installers agreement and no warranty void, as they've worked together before (and get advice off him).  e.g. it's "fix this issue" not the entire install is at fault scenario.

I was considering the other option if BUS fails (e.g. our esteemed Government pulls it), but looks like that's going through now in hope if it's pulled tomorrow, our application is in the system…

So now it's a waiting game until next year (again!!)/hope specialist gets a free day and comes over before then.

I have managed to pull the top of the WC down to 42C now the house material seems to be back to a decent state.

So I'm now fully back to where I was before works done on the 5th of November, a situation totally unavoidable had the installer followed the specialist's advice laid out in July.

Least got movement on the BUS (only taken 2 years!)…

Noted.  At least you now have a confirmed route forward and a warm house.  That, in itself, is a step forward however frustrating the wait.  Installer needs to go back to school!

Oh the installed needs to go somewhere, that's for sure! But unfortunately with them contracted by the builder/the BUS etc I've still got some overarching presence of them (ghost of 2 Christmases past now…).

As ever I'll report back on how things go.

My final thought on this, is as it's 48 pages of waffle from me, back and forth.  It would be good to create a summary post, if an admin wouldn't mind - once all is solved.

I could list how conclusions were made, the sorts of things found etc.  In some hope that should this happen to someone, all the mad points are listed (LLH with arrows on back to front etc, strainers blocked, primary circulating pumps, PCB F5 fault, bizarre warranty statements).

And as ever, appreciate everyone's input and suggestions, wouldn't have got this far without them!
