if the stud is already in I wouldn't worry about it.

all that info is great but not really of any use. What is your heat loss calculation ?

how are you using that tape to seal against the wall junction ? It's not an approved method its a bodge. Use a real VCL and seal the roof properly, that means no cuts and sealed onto the internal walls.

make a simple mitre box out of scrap timber with a slot in it to guide the saw, dead straight cuts every time.

no such thing as a hybrid roof. warm roof requires a real VCL layer brought down onto the walls and not punctured by downlighters etc. Taping insulation IS NOT a VCL and wont work especially in high moisture areas like kitchens.

UK alternative will be less than half what you have been quoted by rational. R7 Flush Casement triple glazed (very nice window) whole frame u value of 0.84

screwpiles can be cheaper depending on the depth traditional piling needs to go down. Also worth getting another SE opinion. https://www.screwpilesltd.co.uk/

25mm xps on floor isnt really going to do much. you want 300mm, while it is a couple days disruption it will enable you to have underfloor heating and mitigate the massive cold bridging into the walls.

it is baffling. I've came across no one who is happy to have any building at all next to them. So the planning process gives the appearance of them having a say when in reality they have none. They can moan about all sorts of nonsense none of which will make the slightest difference. The plan is made in closed rooms which areas that are going to be built on decided, farmers to be made multi millionaires for selling a couple of acres and not have to worry about paying a penny of inheritance tax etc With the greenbelt being off-limits everything has to be rammed into what's left making villages and towns unpleasant. With the amount of ££ involved an unfixable problem. 2021 alone £315 billion was lent out in mortgages. No politician is going to mess with devaluing that by even 10% and expect to continue to have a career.

solicitors tricks like this are very very common. The more crap they can request the more time they add to the clock/bill.

yep do this. 300mm eps is good start point.

rubbish. only valid planning matters are considered by the planners and more importantly the inspector should it goto appeal. 99.9% of parish councillors cannot distinguish moaning and opinion with planning policy. They have no option to make any sort of representation to a formal planning committee either, perhaps you can link us to some minutes if this isn't the case where you live ?

jewson use estimators online.

parish councillors have zero say on the detailed plans. Don't even bother arguing with them. All the parish committee can do is recommend or refuse and because its joe public they are clueless on actual planning matters 99% of the time anyway so are ignored by the planners.

soft wood linings are hit and miss quality wise. MDF liners are bang on and you can use wide slam strips instead of the narrow ones for a more professional look.

starting to pick up, the 68.3p kw/h is very nice

there is some intelligence to it for sure, it 'knows' what your solar profile is so keeps a bit spare.

the builder wouldn't have costed in the time needed to tape every slab on insulation, if he had he wouldn't have used 600 centres either for the trusses as it results in massive waste of PIR. You need LOTS of http://www.gapogroup.com/ tape, get busy.

how have you set it up to charge ? Mine is programmed with the cheap rates (im on 3 different rates depending on time of day) and it keeps to them perfectly.

https://www.estimators.com/ send them the full plans and elevations. You get a build price EXCLUDING footings.

i would fit an eaves ventilation tray first to keep good airflow then cram as much insulation as physically possible into the void. https://www.roofingsuppliesuk.co.uk/collections/eaves-ventilation

only put them external if your going for the 70's council estate look. They should feed into a chamber as soon as practivable to allow for easy rodding. Vent them to a roof tile vent.

good luck getting a service call from Poland when inevitably something goes wrong. must be crackers.

probably the type of brikkie who thinks gauging buckets take too much time as well..

fantasy land you need sound tests, fire regs, SAP/heating, etc etc
