Queried builder that specialist has in fact been booked in tomorrow and he’s sent a message along lines of change of plan due to MCS and BUS requirement, will call me tomorrow…
If he’s delusional enough to think he can wrangle original installers back he’s out of his mind.
My understanding is MCS isn’t installer tied (just need a MCS certified company to certify the install, doesn't need to be original installer?) and is tied to the installation itself? Want to prepare myself for the call tomorrow. Sick of people trying to deceive me.
Obscene at this point and people are still being obscure with me.

Thinking about it BUS is installer tied I believe. As a householder you have to consent to a particular installer claiming the BUS grant. I dont know the ins and outs of this needless to say, for that it would be necessary to read the regulations and probably detailed documents on operation of the BUS.

Seriously doubt they've even applied for it as it has a 120 day period by looks of it.
Utter lunacy this has got to this point.
Specialist tells me been told to come next week to let system run over weekend.
So now the builder is lying to me. He told me yesterday had booked specialist in to come Friday.
Not home yet but no idea if hot water has run. Temps still aren't 21c, rooms at 19c. No way over weekend they’ll get warmer as panels had them around 18.6C last night so clearly its still buggered with a poxy 0.4C increase.
The building trade is just dodgy, the world over it seems. Did you see the video of that vast bridge in China that collapsed earlier in the week. Now thats a serious case of dodgy builders!
Your issue should have taken half a day to fix or a day tops, it just needs someone present who understands what they are doing. What I don't understand is why your builder is incentivised to persist in asking the hopeless installer to return unaided by someone who actually understands heating. Presumably he is somehow incentivised to do this otherwise he wouldn't.

On way home told by builder need to give installer 7 days to setup and monitor system. Inform him take issue with this, 50L install was done last Wednesday, pump indicated as faulty. Friday - Pump replaced and told its all working. To me that’s commencement of 7 days.
Temps slide. Monday observe no flow on flow setter, specialist advises to turn off.
Tuesday instruct removal of installer.
Later Tuesday told as installer has PCB fatest route back to heating and hot water back on is installer attends next day. Agree under terms after which no longer on site.
Install attends Wednesday, replaces PCB - F5 fault. Tells me all he can do, manufacturing item issue. Grant call - engineer to attend next day
Now - Come home to no rise in temp and shine light on flow setter revealing zero flow. inform builder to ask installer what to do as clearly he insists they're now somehow back, due to 7 day monitoring.
Informed they'll attend tomorrow as need 7 days.
Honestly totally taken a back by this situation.
They’ve had 7 days, it would appear am back to Friday now.
@crimson if you have one installed, are you able to check the ball valve filter just before the outdoor unit?
This was the cause of my lack of flow
That's not a ball valve filter; I know a cafetiere when I see one 😉

Sounds like it needs to be topped up with water, because the air has started coming out of the system.
This is normal and is almost inevitably going to happen. I topped mine up at least half a dozen times in the first month, just the same as you would have to do with a new boiler based system as air comes out.
Of course Im not saying that will fix i,t but zero pressure needs to be fixed not least because it will normally cause the heat pump to stop working.
There are some very basic fixes that are getting in the way of finding the actual problem, with, I fear, each person involved (quite possibly including the specialist) trying to protect themselves from liability rather than trying to fix the problem.
Im guessing its your builder that is ultimately liable to you?
