Maybe you misunderstood my suggestion? You simply tick different boxes. Job done. No one is ever going to check. Find the right one, they wont even visit the house.

My simple plan is an aircon unit in the main bedroom. Thats it. Downstairs living room, being 170 years old with 2 ft thick stone walls, tends not to be a problem anyway Cooling a whole house is not a cheap undertaking.

Reasoning with people wedded to an ideology is indeed pointless.

That not going to be very accurate though is it. I know peopl who run their house at 15c throughut winter. I know others at 22. The difference in energy comsumption if its a poor house will be big. And then some will have log burners which they use to boost temps, which will often be run "for free". And of course, you can lie. Easily. And boost your epc. Problem ultimately is, whatever system they use is trying to get a semi accurate answer, when the inputs are a bunch of unknowables. Frankly, without an air leakage test, its all rather pointless.

Next time, use an assesor that asks you what outcome you want on the report. Problem solved!

First ive heard of it. £1 a kWh? Why isnt everone with batteries doing it?

But largely useless to me. Plus unaffordable. My wife might get one if it ever makes economic sense. Me, no. I enjoy driving. But not in an EV.

Or another car 🤪

For clarity i was talking about electricity specifically.

Id like to think the energy sector is doing well. Its like christmas day, every day! I wasnt just thinking about industry, but everybody. The more you spend on energy, the less there is to spend on everything else, and that impacts all industries.

Agree that some form of breathable insulation is better. Depends how much space you have. I fitted 50mm PIR to the slopey bit, but i only have 3 inch rafters. If they were 6 inch i may have done different. I then installed rockwool in between/over the joists. So only a small part is PIR. These were sealed up around the outside with the illbruck 330. I did quite a good job, but not as good as id have liked to do, but with the roof off, time is limited. My last house had the same, but the PIR was "loose" in most cases. I lifted some up and it was completely dry underneath. There was just plasterboard underneath to the room. No VCL/membrane etc. So yes, its a "risk", but not sure its a big one. Nail a VCL to the ceiling inside if you are worried.

Energy independance is a (mostly) seperate debate from the cost of that energy. We still have some of the most expensive electricity in the world. That has a significant (negative) economic impact. And thats, to a significant extent, driven by the market structure of the UK. Thats what needs fixing. And if those who say renewables are cheaper, great, when can we benefit?

At last. However, this statement seems rather at odds with many of your previous ramblings. So which is it?

Its still BS. The only effective maintenance one can, once its clogged with silt, is to take it up and relay it including the base material. Which, quite obviously isnt going to happen. Even basic cleaning, almost no one is going to do Just because someone produced a pretty graph, doesnt change reality out in the real world. I just look at what really happens, not what some desk jockey, paid by those pushing a product produces. The principle of SUDS is sound, the application is mostly lip service, with products that clearly wont work long term. Proper solutions are expensive. Permeable paving is essentially "delayed" hard surfacing.

Im no civils engineer, but 6n backfill has fines it it, which will migrate to the bottom, ie the pea shingle and eventually block it up. Its not what i would do. Mind you, a structure like this behind my house would scare me. Though not as much as the ones ive seen not far from here that use the interlocking wood system. In his case over 4m high with the houses at the top. The timber will be rotted away inside 10 years and the whole lot will fall down.
