Arguable isn't it ?
For example I notice they are thinking of doing away with the 1m from the border limit for heatpumps, so you can place your pump pretty much on the boundary - in other words enabling people to move their noise further away from them and closer to their neighbour.
So great if you are the one installing the pump. Not so great if you are the one having to put up with the noise from it.
Personally I think they would be better off insisting that installed pumps must be quieter and doing away with the border limit.
