They saw you coming, wire is wire and although I agree nor all wires are created equal they are more equal than a. The average ear can tell any difference and b. The fidelity of the cheap speakers, well cheap by comparison to the £1000 wires.

Yes but what about the households where there is neither a gas supply or a heatpump. EG here we are on LPG I doubt that is on a central dB. To be fair we are on a 1200l tank but other neighbours are on bottles. Overall I like the idea of not paying the green levies if you have invested in a heat pump and have disconnected the gas. An alternative might be to move all the green levies for domestic consumers onto gas but although his has been discussed the inherent unfairness in this approach might make it challenging to implement. The essential problem is that almost anyone can have a gas boiler installed almost no matter what sort of dwelling they are in, assuming mains gas is in the street and there are many places that cannot have a heat pump.

Are they grout stains? In which case might be worth getting a small bottle of concrete acid - but TRY IT ON A BIT OF SCRAP LIMESTONE BEFORE GOING FOR IT. LIMESTONE is remarkably reactive. Screwfix do something called eradicrete which might do it.

Fill and pressurise, but don't over do it, the UFH pipework to prevent it being crushed maybe.

Not sure but does the plastic nut not unscrew on the new one to offer a flat face connection that undoing the nut on the old one will reveal thus allowing a direct connection. Old nut onto thread revealed by unscrewing the new nut. There is probably a rubber washer in there somewhere as well so use the new one.

Now that's my kind of electricity bill. We have not decided to invest in a battery yet but probably will once the house if finished so we can use agile octopus, the PV, the battery and the ASHP to optimise everything. Do you have PV diversion to the DHW, I dimly recall that you do but I may have that confused ?

We turned on our system in April (11th) since when I have become what the other half calls a Solar bore. 6.8kW export limited to 6kW, - MCS accredited and here is how it is going: almost 1MWh exported in May. Agree the house is not finished yet but its fun to see it paying the electricity bill across this place and that. Octopus have taken us off monthly DD and we will now only get a bill when we owe them money!

No idea how to attract residents - have you appointed an agent and have you advertised on ErinaceidaeMove.

The accepted wisdom is that MVHR is only effective in a house with good air tightness although just where the line is drawn is hazy although @IanR does give a line above. Passive house air tightness is relatively hard to achieve unless the design accommodates it because, as @JohnMo says, it is all about the details. I think that for our house we had a total number of air gaps equivalent to less than the area of one credit card (achieved 0.2 on the Passive house scale or, in our case as form factor is everything, 0.3 m³/m².h on regs scale which is about 1/26th of regs). So if you are not going for a good air tightness then as @IanR says you should perhaps adjust your approach you can see it as either all in or all out. Halfway house - pardon the pun, is not sensible because the middle ground incurs costs both ways EG you install MVHR but is just adds to running cost.

Looks great, agree with @Thorfun on the pocket doors we had three but have gone down to one now.

Not so much manufacturers, manufacturing is done in other places, but designers really.

Once there is no meter you will not be paying any service charge and as such your local gas infrastructure company should be asking you when they can come and remove the pipe back to the road. There is no charge for this service down here so can't see there should be one there. If you think about it you are a 'risk', in the sense that there is now nothing to stop you abusing the connection and taking an uncontrolled gas supply, they need to manage and the best way to do that is for them to remove the pipe.

This would be my worry also.

Welcome to THE forum for people like us. Looking forward to travelling your road with you.

Not needed because if you, or some later occupier, wants to go back to traditional wiring they can do it at the panel because all the wires are there. So I would probably suggest, as it what we have done, only one tweak and that would be to make sure you have enough ways (wires) to/from each switch to allow conventional wiring so if the switch would, in a conventional scheme, be a cross over then you need 4 ways plus earth or a change over then 3 ways and earth.

Respect!

To late if you want anything other the simple you need to get the wiring in for the speakers and a power point for each woofer, power points for all the speakers if you are hoping to go for wireless.

Get on your local neighbourhood forums and ask around. That might pull someone out for you. Perhaps a retired brickies partner fed up with having them under their feet might give someone the push they need to get back into the fray.

You need to think about the treatment inside the room where the Velux is so you get splays where and how you want them. We got ours so it was a direct drop down the walls - the wall goes straight up to the base of the frame but you might want a slope. Also don't forget that the flashing will have minimum dimensions. We have just one row of slates below ours before the hidden gutter.

Good question - at the low end you might not be able to show enough ventilation - but you can always drill some more holes, at the high end won't you be outside building regs?

That looks bad, at least they are going to replace them, but that does not exclude poor design.

Yes, think that changes takes effect today. I think they are dealing with that for small sites as well so some of the habitat rules are being removed for small developers, which includes self builders!

You do need to ensure the new one will match the lamps - either incandescent or LED.

The problem with N+ consequences is that they are often, usually probably, unintended because nobody looked at / for them at the outset and in the end you can go to far in trying find and manage them that the cost of doing anything closes everything down. This is the same at the other end of the problem with requirements complexity. So if you want a new way to buy / sell electricity you will set out a few requirements, these will have relationships with one another (interdependency) and you will want traceability as well. You are now looking at the N+ consequences of many interrelationships in the requirements which makes life difficult so most people don't go much beyond N+1.

It's mad but breaking the link is tougher than most people think. It's all about the 2nd and 3rd order consequences (consequences of consequences and the consequences of those consequences).
