This is what bugs me with this whole battery storage and DNO restrictions nonsense. It would be simple to design a system that just used a CT on the mains feed to ensure it never exported more than 3.68kW but could deliver a lot more than that from the batteries when the house was using it.

Sory i don't have a picture. But those piles in the picture above support a rectangular building. The wall in the foreground supports the end of the building at ground level and the rest of the building is supported on the widely spaced piles. The point of the post is rather than try and get a piling rig on soft sloping ground they did it all with a digger. Removed a lot of top soil and then for each pile dug down to something solid then cast a 1 metre square of concrete then formed a poured in place concrete pier onto that concrete pad. Then put most of the soil back then membrane and gravel to top it all off. All the tops of the piers are at exactly the same height and gives you an idea of the slope.

That design is so similar to what my neighbour did.

A picture of the plot might help? A neighbour here on a tricky plot built on piles, but not with a piling rig, but with a very skilled digger driver excavating a square hole at each pile position pouring a 1M square concrete pad, then forming a concrete pile on top of that, then put the soil back. A bit like the post above, not many piles, widely spaced and the house was then built on a substantial timber base formed over the pile tops making it an above ground house with clear space under it. Nothing more heavy on site than a 6t tracked digger. Here is the resulting piles he built up from

Yes ours is. Only one mouse in the house in 6 years, and that was through a partly open velux window. The last house, they always got into the loft. The ridiculous practice of a cold ventilated roof with the mandatory vents large enough for a mouse means that is inevitable. And why I am a huge fan of a warm roof design with all insulation and air tightness following the roof line.

Surely it would be better to get mutual agreement now, and build it as a party wall straddling the boundary with you contributing some of the cost and an agreement that when the time comes you build up to it for your extension. that would probably involve agreeing roof profile and you joining onto they roof when you build yours. Anything else is a compromise and extra cost for you both.

Interesting topic. A short term rental (i.e. holiday) now needs and EPC so I assume letting caravans is still allowed as they are EPC exempt? The only person that could answer that is the council who should be able to confirm a caravan is EPC exempt?

If they were damp when fitted they would be a lot weaker and the screws would pop easier. I have never known good dry new boards failing from the moisture in the plaster.

And he started with a nice flat site with ground that already looked hard and stable (what pre preparation was done?) Now try that on our sloping site with an over thick layer of soft top soil containing vegitation? One good thing on there, he glues some sort of cement board to the upstand outer edges. that solves the often asked question on here how to protect them after a whole house has been built but still nothing covering the EPS upstands. What was that buried flat metal strip around the perimiter for?

It was not many years ago I replaced the fan in an Electricaire unit, spares are still available, and even more recently I installed a new one, now being marketed for heating large industrial spaces.

Well one of the thermostats is dud. I would say boiler thermostat. The water exiting the boiler should never be near boiling, so even a failed cylinder stat should not cause that. I bet the radiators are scalding hot to touch. Until you get it sorted, do not leave the boiler on at all over night, or while out of the house, and watch it like a hawk when in, first sign of boiling or banging turn boiler off.

A well written description of why I would never have "smart" heating controls. My hard wired programmer and thermostats never go off line.

I really don't think it would be the boiler heating the hot tank that hot, much more likely the immersion heater is turned on and the thermostat has failed. Immediately find and turn off the immersion heater switch. Boiling water venting to a plastic header tank has been the cause of more than one very unpleasant death and why the law was changed for a secondary thermostat in immersion heaters. Don't ignore it, act NOW before even replying to this thread. I would add, turn off the boiler as well, and run a hot tap to run off some of the boiling water out of the tank.

This sandwich SIP panel you are describing is exactly what caravan manufacturers have been doing for decades to produce lightweight, thin and strong floor wall and roof panels with foam insulated cores. It would be worth a search to see if you can buy for instance caravan floor panels ready made? Here is one such product https://www.panelsystems.co.uk/news/2019/04/lightweight-panels-for-a-variety-of-applications I think the challenge will be finding something for sale in a small quantity at an affordable price?

No, it would mean the cables being in a hot duct and probably insulated so they would have to be de rated.

Did you get a measure of the diameter of the red and black wires into the main switch of the consumer unit while you had the cover off? I'm wondering if that is 16mm? What's that unlabelled B50 next to the RCD feeding?

And ask them if they were happy with their builders. Only is they say yes, ask them who the builders were. A surprising number we spoke to said they would not recommend them.

Just get the narrowest off the shelf door liner and fit that then plaster board up to it. As you say just like an external door. You now have the choice of door liner flush with one edge, or in the middle.........

Crucial to the viability of an extension is how it would fit with the rooms that are there, i.e. not leaving existing rooms without windows or too small, and not making it awkward to get around i.e. it must flow well. If there are similar houses to your with extensions look up their planning applications or even go and ask the owners if you can have a quick look around to see how it works.

If an MVHR us unballanced, it will either suck air in, or expell air through the leaks. Even a house with a good air tightness test result will have some leaks. That imballanced and unwanted air flow will of course not benefit from heat recovery. Nobody is suggesting a house without opening windows, building regs would not allow that, and there is nothing wrong with opening a window in a house with mvhr. For much of the year our bedroom window is open a bit as even with no bedroom heating it can be hard keeping the bedroom cool enough. As a general rule, you can open one window, or one door in an air tight house without getting much of a through draught from that even on a windy day. Do check your MVHR from time to time. Our inlet vent became blocked. I sort of sensed something was wrong when I started to notice the bedroom becoming a bit stuffy (when the window was shut) and I confirmed the house was being depressurised. The inlet vent is a common type with a coarse gauzze mesh to stop flies getting in, and that had become very clogged indeed. You can't get to the outside of the mesh to suck the debris off so I got the compressor air line on it to blow all the debris away from the inside. Normal operation restored and it is now an annual maintenance job. As a secondary indicator, annual heating usage had crept up by about 5%. Now the blockage has cleared it has gone back down. That shows the extra heat loss as the MVHR was not operating properly.

Do NIE ask for calculations? If not just pick a low figure like 12KVA and re apply. They are not going to connect you with a thinner cable just because you ask for a low rated supply. If they question the change, tell them your original estimate was made by someone not understanding how it is done, and now you have a more accurate understanding of the energy needed for your house.

And you could also add that he did not serve the correct notice on the owner of the land (as you would if applying for PP on land you do not own) so the application should be invalid because of that.

So it is just the handle broken. A smaller pair of mole grips would be a closer match to the other handle.

In your formal objection to the planning application, state that the applicant does not own the land he is proposing to use as an additional parking space, so he would not be able to create that extra space, thus the application if approved would leave insufficient parking space on the property.

So based on that you requested a 40KVA 3 phase supply and they came back with the big quote? NOW go back and ask what you could have without major network upgrades? In my case the answer was 12KVA single phase which ended up costing me £1K and has proved totally adequate. If I really needed 3 phase here, there would be at least half a mile of single phase 11KV overhead line to upgrade to 3 phase then a 3 phase transformer to install. That is likely where you get the silly high prices.
