Give your local building control office a call, and ask them to come out and inspect and advise. Most of them are a helpful bunch. I bet the developer self certified and dropped the ball on landscape here. Even gravel will get bunged up with debris and allow damp to breach, it's a crappy job to keep it "clean".

Buy the cleaner that goes with it. I have a love/hate relationship with expanding foam!

Theory works I think, I would keep a few bricks helping hold that PIR in place just as a pure belt and braces approach.

Can you really hear anything from them at 2km away?? I've visited a few wind farms and they are loud when stood directly underneath on a windy day... But 2km!? Definitely never found the noise intrusive carrying out business around the wind farm itself. Compared to typical road noise, wind noise in your own property, a MVHR circulating air etc etc...... I really thinks it's worrying for worries sake. I think they are incredibly graceful thing,and each one a middle finger to OPEC, Russia, etc! Edit, A14 view I was referring to, as you drive up over the hill and see them in the field in front! Really cool.

I'd love wind turbines a couple of kms away, I think they're amazing. That view driving up the a14 near corby.... Gorgeous!

I am sorry OP, this (expletive deleted)ing game can be a shitter can't it!!!

We have SMART aluminium windows and front door, not best performance on paper, but that's aluminium for you. They looks good. Our (expletive deleted)ing surveyor put then down as the wrong design though, which wasn't realised until they arrived, I'm still mildly pissed off about it, but oh the joys of self build and the quirks of it....!

You might be hitting your limits here, 40mm isn't much insulation, and that is cheap stuff laid there. UFH pipes are pretty crudely laid. 22 degrees in a hallway would make me believe rest of house is probably warmer then that, esp upstairs. Might need to run heating a couple hours longer during very cold periods Replace laminate for tiles might get you an extra degree or two more. Are you able to upgrade insulation anywhere else? Loft? Draft proving etc? At the end of the day heat in vs heat out is a limit every house has at some eventual point, less insulation lowers that point.

It's trickier as the noise would be a lower frequency dull drumming! Like I said doesn't bother us, and I am pretty twitchy about sound..... The water dripping off the wall onto the window cills. .. That annoys me!!! (but I get over it)

Sedum would make a massive difference as it would cushion the rain dramatically. Weight and cost would be a headache though. We have a warm roof, 150mm PIR and a wood deck.... Can't say it's a biggie. You do hear heavy rain, but that's the Named storms everyone hears! Wind is louder then expected, but i think as part of the room has solar panels stood 150mm up off the roof, so it's probably the wind ripping through them. Not sure what noise you're worried about if I'm honest! Hearing the rain falling is no different to it blowing against a window which you'll never class as an irritant!

We knocked the building down the second bats were mentioned, don't need planning for that! We had a full ecology report done which said NO BATS, but planning warned they'd want a bat survey anyway, due to a planned october/November start of construction and confidence we would get planning approved, we pulled the demolition forwards, then a week later sent a very apologetic letter back to them. There were a few grave warnings on fines and penalties, but the risk of delay and costs made the decision easy. It helped that our new build was broadly speaking reusing the existing footprint (project planned as extension, but swapped to a full rebuild) so had they forced a rebuild we'd have made it work. We did have a real fight over trees, had a full tree survey which stated our garden was already over subscribed with trees. Planning wanted a full tree replanting plan, for the 4 small, low value, excessively aged trees. Took several weeks pushing back on it. An hour with a chain saw pre project, and those trees would never have existed had I known the headache they caused....

You guys are going to shit yourselves when you realise the impact on insulation when you open your front door on a cold or windy day!! 😂

Like I said, if you truly were worrying about it a moisture meter poked through the carpet would confirm if you have a leak there, that and obviously a registered pressure drop on system. If a joint was to fail eventually, it's only a days worth of DIY to fix it all and relay a screed there.

We've had compression fittings last fine. Reality is, you'd detect with a damp meter through the carpet if an issue was suspected. Carpet lift and refit no issue, fix, refit. ... Few £100 and days work should worse case happen. Worse shit happens. Average house probably has several dozen pipe joints all over the place! Get them rejointed, pressurise over a weekend to ensure pressure is fine... Forget and move on!!!

Any new EV launched in the last couple of years would fall into my catagory of 'battery will last longer then rest of vehicle', especially if the battery was designed and developed within that time period. LFP batteries last longer then NMC type, but are cheaper, lower range, slower charging etc.

Only talking to automotive batteries, and modern chemistry only. The leaf battery was launched about 15 ish years ago? Mobile phones are also probably killed off with aggressive use and fast charging! They are a totally different chemistry as well.

For what it's worth battery technology is my speciality, and premature degradation doesn't exist on modern battery types. Automotive stuff (other then random hardware failures) is lasting significantly longer then most expected. Fast charging /fast discharging very regularly can have an issue long term but v2g type tech is tickling the battery, which would probably be the difference if it lasting 250k miles vs 300k miles! Ie beyond cars usable life.

Yeah, when our heating shuts off it makes a similar noise, and probably last for 30 seconds or so then abruptly stops! DHW doesn't make the noise. Have to admit it took me a couple of months of getting used to the noises and quirks or ASHP operation... But after 6 months it's working well, doing its thing and even a week of minus several degrees it did its job well!

And that's enough Internet for me today!

Does it make the same noise for DHW? Just turned my DHW off and after several seconds I hear the sound of actuators then it just shut off, no noise like yours. However I THINK I hear a similar noise to you when I shut off the heating, via UFH, but only for 30 seconds or so. I presume it's the system shutting the UFH Actuators off, sealing off flow, so the water is forced past the bypass until ASHP shuts down? I'm guessing... But will investigate when in gone and the heating is on next week.

I can't seem to load it, are you able to post to YouTube?

Can you post the video here? I have a gen6 from joules, and I also get a whooshing sort if noise at the heating programme terminates, but I think I have a bypass loop.

And those are the important bits to remember!! Our 9 month went into nearly 2 years... And we had some harrowing evenings crying over the spreadsheets and costings as it all slipped out of our control. I remember March last year asking the builder's office for the final electrician's bill, and her coming back to me and saying 'just over £23k'... And me mid motorway drive dull brakes emergancy stopping onto the hard shoulder in a blind panic... Only for her to go 'oh sorry... No that's the total months bill... Let me get you the right figure' and for me genuinely crying in relief as I accelerated off again.... For her to then come back to phone 5 mins later and say 'no, sorry again I was right the first time, it is indeed £23k' for me to then end up back on the hard shoulder. He was a (expletive deleted)ing shyster. BUT having been in for 9 months now, we do regularly look back and laugh at most of the horrors we went through, the panic, emotion, distress and anxiety which at the time were all consuming. The shit we stressed over which is irrelevant now, and the decisions we forced through against advice and shouldn't have, and the thinks we did get very right... BUT we are thoroughly pleased we went through it, I definitely feel it's made me a more resilient and philosophical person and I think I handled it pretty well at the time all said and done. It also makes us appreciate the place more, and you'll be amazed at how much you forgive and forget when all is said and done!!! End of the days, it's just a (expletive deleted)ing house. Most people won't know, care or take any interest in vs schools in the area, it looking nice and what are the neighbours like? Grit teeth, ensure and just survive. It's all worth it on the other side.

I'm sorry OP, self building can be a long hard slog! A degree of getting screwed over by someone is par for the course, especially if you are average Joe self builder where you have a job, family and are not die hard involved in the build itself. We got taken to the cleaners by an electrician's final bill to the tune of £20k more then expected, he was a useless shit as well.

I'm inclined to agree with Nick!
