Hi, Yes, ASHP is for hot water and heating (UFH on the ground and rads on 1st flr) Looking through his O&M pack, I get the impression there were several contractors no coordination. The site is still being developed and responses to my sons' issues have been slow... I don't want him to threaten legal action but I'd like him to be armed in case he has no choice.

Hi, Can anyone recommend a professional close to the Cambridge are? I'm specifically looking for someone who can inspect a 'green' new build and report on its design and any failings/strengths. Some background: My son has recently moved into a new build c/w ASHP, solar PV and MVHR. The house is constructed using, what looks like, a type of SIP panel with an additional 50mm of graphite EPS; to take render. Marketing material claimed 50% more air tightness than a traditional build, but his permeability test shows 5.41m3h @50Pa. (Technically better than BS but not really in the spirit of the development) EPC is A (for what its worth) 1st issue: His electricity bills, for hot water, seem quite high @£200 per month (2 people) He has been advised to leave the HWS flow temp at 44degc 2nd issue: The house is hot on the West side and rarely drops below 24degc and were not even close to the hottest part of the year -I feel it should have had some shading? 3rd issue: The controls are a mess - Its all based on Samsung Smart Things but none of the devices seem to communicate. He has no idea what, and when, his solar PV is generating the room thermostats are basic with no comms back to the hub, and they have installed some standalone sensors to track temp/humidity etc. Many thanks,
