I assume from context that the "house values" you and several other apparently British posters are using is what in the US we would call "home prices"? Or have I guessed wrong and it is being used more like "family values"? If the latter, what kind of values are meant?
It's home prices indeed AFAICT. It's fairly bloody-minded ti think house prices will go down with nearby renewables, it'd be a small blip if any at all. Give me wind turbines around and take away the cars and delivery motorcycles.
