You'll remember from your Air Law that the ANO is already clear on what needs lighting, and how to light it.
The professionals here don't need a PPL to tell them that there are legal requirements. The discussion is about whether the requirements should be made more stringent in order to improve flight safety.
The cost of installing and maintaining warning lights will be much more than a grand.
Blind Pew was referring to the cost of FLARM not warning lights.
In any event, "much more than a grand" to instal and maintain warning lights is peanuts in relation to the £multi-million cost of constructing high rise buildings and, if lives are saved, worth every penny.

All three commented on inadequate lighting on the Cranes so that seems to be the sentiment with non aviation people in London.
That is a widely held view in London, and not only amongst non aviation people.
I don't know if this applies to the Vauxhall crane but I'm told that some lights on some cranes are solar powered.
I wonder how efficient/effective solar powered lights are in UK conditions, especially in the winter months.
