Try my secondary glazing idea that I suggested for your main windows a while back.

These people could supply all the kit needed. Any GRP fabricator could do it, but no reason what you could not do it yourself.

Why not coat the PU/PIR sheet with GRP, then fit into place. Works well on boats.

Think this may be a social class issue. Just put room numbers on everything.

Can you soften it with a blow torch. Or put some mix in a barrel and light a fire under it. Pour into hole, put a metal, or even timber, plate over it, then drive over it a few times. Rinse and repeat till level. (Road making materials are, by mass, the world's biggest recycled materials)

So bathed in warming microwaves. Non of us are far from a military base. I used to live and work in High Wycombe, home of HG Air Command. Now I am fairly close to RAF Portreath, and RNAS Culdrose. Would have to cross a 'radiation' zone to get out.

Not on its own, but a few of them on a short circuit scrambling track will sort it out, and you can charge an entrance fee.

Only read your abstract of what you intend to do. Does your incoming mains support this, there will be a drop in flow once all them bends in the pipes and the length of the pipe rums is taken into account. Effectively two different types of heating systems. Not a problem as suck, but needs a bit of careful thought re flow rates, flow temperatures emitter areas and the different heat distribution within a room i.e. where the radiators are located. As I am sure you have read from people that run their HPs efficiently, they are effectively 'on' all the time, so room usage is just a distraction. Treat it as a room that is always at 21°C. (maybe a slight setback at night). Fit as much as you can by all means, the marginal costs difference is minor, and maybe negative. Don't think there will be need for additional wiring, but it does depend on if it is an AC or DC coupled system. Initially get a suitable inverter for your capacity that is acceptable to your DNO i.e. how many amps you can connect per phase. Worry about battery storage when you build the second house, the energy market will have changed (again) by then. You have to fit one, so no point fretting about it. If you put the cabling into conduit, you can fit another cable into it for battery storage (EV charge points are usually in a garage, where batteries may go in the future). Bet that is (expletive deleted)ing noisy, fit quadruple glazing. As an after thought, and replying to this This is why some of us have to do the right thing, we cannot rely on others. It also stops them having to know anything.

I don't understand the 2012 pricing. 2012 was when we held the Olympics. And a good TV series about it.

I think you are misunderstanding the whole concept of 'new generation'. If you accept that we need to replace, and run, extra electrical capacity, which also includes the associated infrastructure, and it is also agreed that the price is fixed until some future date i.e. 20 years. Then wind and solar are coming in as the cheapest. To put it into automotive terms, it is like buying a car. A new Ford Focus is between £24,200 and £33,770, on a finance deal, with Ford's BIK, the monthly price is between £140.48 and £343.84 (https://www.ford.co.uk/content/dam/guxeu/uk/documents/price-list/cars/PL-New_Focus.pdf) Buy a second hand Focus, over ten years old, and the prices vary from £360 to £3, 984 (AutoTrader). No good comparing two very prices. even if the product seems the same, while arguing that they are the same.

I think so. Works out cheaper than new gas.

Did you include landscaping in your plans, think you can get the VAT back. Sounds like you need to remove topsoil, sieve the weeds out, then respread. Maybe start with grass seed.
