Your experience was nasty, and we should hold responsible the suppliers and importers of faulty dangerous goods. There is a thorough write-up here, BTW: https://solarenergyconcepts.co.uk/post/plug-in-solar-uk/

I think that current G98 microinverters will work for this and be safe. (As would probably one with EU nominally-slghtly-different specs.) The key current GB grid restriction is that a Part-P sparky has to wire solar generation into a dedicated circuit (and tell the DNO). And a meter may have to be swapped if it would run backwards, which a DNO or supplier could be awkward or slow about. In Germany for balcony solar the rules were changed to make it the DNO/supplier problem to deal with, ASAP if there is a fire or other risk, else eat the billing errors until the meter is swapped. We already know balcony solar to be safe in practice - the microinverters cut off quickly if the grid goes away for example. I imagine that the ENA (and DNOs) have already said "go ahead" and are cranking out adjusted docs/specs/regs as fast as they can. It doesn't hurt them at all if the politician will takes the flack and the tech is already known and the metering issue can be overridden by fiat as in Germany.

I am not in Brighton! My Motorwind stuff gave up the ghost a while ago, and I put PV along the wall it had been mounted on. But a combination of the two would still be interesting...

I have responsed to the consultation request. Generally in dense urban areas wind generation isn't going to work well because of messed-up turbulent air and noise and flicker and ice-throw issues. But there's plenty of England for which this might work. I also pointed out that single-axis HAWTs should not be assumed to be the only game in town. My tiny MotorWind setup worked reasonably in my very poor location, and other novel (probably not VAWT) designs might work. I have suggested a limit on total swept area or output power or to ~10% of expected output power for a full wind farm in the same location, ie this should not be permitting a wind-farm on the sly, but should allow low intensity microgen energy extraction to support farmers or factories or community projects...

Most urban wind is very poor, and mounting a turbine on a home makes for a lot of vibration noise. If you are in rural area with a bit of space, especially coastal, small wind can make sense.

Is there no rear space beyond the conservatory? Do you have a flat roof, eg on a porch, that might host the external unit? https://www.installeronline.co.uk/green-energy/installing-ashps-on-roofs-and-walls-what-installers-need-to-know/ There are variants without external units, eg: https://www.etherma.com/en/blog/heat-pump-without-outdoor-unit

That is not safe, as clearly no or bad mechanical strain relief and exposed wiring that isn't meant to be seen or accessible. Live mains voltage might only be a screwdriver or paperclip jab away. This may be indicative of other sloppiness and poor H&S and compliance.

Our use of the dehumidifier is mitigation for a place where ventilation is inadequate. But given the short likely remaining life of this building, though I'd like to fix it with (say) more single-room MHRV, it doesn't seem worth the candle.

Because our gas boiler kept expensively failing so replacing it is expected to be a financial win, and I am definitely a supporter of electrifying everything, and heat pumps are the main focus of my PhD research!
