Don’t be afraid of contacting them, they are there to give guidance. If partitions aren’t required by regulations would it be beneficial to fit them just to reduce noise transfer etc?

I would view it as a service void which wouldn’t need to be plasterboard. I would call or email BCO just to confirm.

Welcome to the forum. What does it show on your building warrant drawings? That’s what I would be using for reference, Scotframe would also be aware and would provide the necessary materials.

I had multiple brackets on JJI joists so I made cut outs in the plasterboard with the multi tool.

Where does the ASHP drain go to 👀

Might be better with something like this then

That is a grease trap / gully, meant for kitchen / utility. Just a rain head & elbow is all you need.

Welcome to the forum, you are in good company 😬

40 grit sandpaper 😉 I thought this house was actually finished…?

Welcome to the forum. Lots of ASHP info available if you search for it.

@LaChab if you decide to use DuPont Tyvek Airguard I have a new roll leftover for sale.

It looks like it’s closed (screwed in) There will be no flow to that circuit (no water in the meter) just unscrew - anti clockwise to get the desired flow & there will eventually be water in the meter.

Living with the in-laws I can’t not afford you Nick 😎

Good advice from Nick & very generous offer of help. There will be a solution, I’m sure the heat pump can be run without the thermostat. The most important thing to do is PM me Nicks number once you get it, I need to start my plumbing very soon & I need him on speed dial 😉😬
