The floor insulation won't be "done" because in your quote it says " supply 100mm insulation " which makes it your job. Just like the purchase and install of the wall insulation, loft insulation, and plasterboard too.

have you now checked the motorised valves and their switches for function? Might be worth looking next at the tank stat too?

Looks lovely, and is very much what we aspire to, some time next year hopefully.

stats don't matter as the wiring box interfaces the two ends...

hang on a mo... There's a cavity between timber and block that needs closing with a firestop too don't forget, and it'd expedient to mount the window to that rather than the blockwork.

Odd that the Scottish regs are still so woolly whilst in NI they were very specific about MVHR even in 2012- which is the latest regs... just in case it's ony use: http://www.buildingcontrol-ni.com/assets/pdf/TechnicalBookletK2012.pdf

Is the DIBt essential? It was alleged to me that the only real difference was a self-closing door and loads of documentation...

I vote for sh*t happens, and there's a dodgy capacitor or backup cell somewhere which has been hiding, waiting for a power fail.

car wiper refill with the rearmost rib sliced off?

sorry... 200mm

what about the other way- I've 110mm rainwater pipes to tee into 20mm perf twinwall. Holesaw, or just let them lie in the drain stone beside the pipe?

^this. I had some holes designed into our steels that match in with the pozijoist webs. Very handy.

you don't "keep the heat in", it takes flow to make heat in the rad. You're looking for a temperature differential across the rad so it (say) flow is 55c, the return should stabilise at (say) 45c. Less flow= greater differential. The pump can only flow a certain amount so if some rads have too much flow others will lose out- that is, have too much of a differential.

means the tank is unpressurised, it vents through the tap. Our Brita filtertap is the same...

Dunno just how tight funds are, but what's wrong with precast?

but as long as you don't mind the Fgas side of things there's a Split here: https://www.ebay.co.uk/itm/air-source-heat-pump/223736171110

where in the world are you?

knowing that loading and shrinkage are two separate things, I just ensured our blockworkers left the top a wee bit shy for now. We've clipped eaves (no soffit) so any remaining gap will be sorted by the render , at some point later in time. Under the window frames tho is different, there's an easy 1/2" gap filled with Compriband there.

^agree.

I'll see if I can find any but yes that's pretty much where I am. I may run a narrow strip of leadax down the edge of the renderboard before the render goes on tho.

there isn't a second hose by any chance? An airlift to discharge clean water?

passed 1000kWh of generation at the weekend. yay! PB of the upstairs ceiling nearly complete, loft insulation half done.

travellers + buy would be a strange concept locally...

red is slightly more flexible than blue, the green stuff wasn't around when I called up to inspect and collect some stuff.

you're still not in control of your project, are you?
