@Dirtfarmr@PaddyBriggs@moiracathleen@BorisJohnson@POTUS@polit2k@Sysparatem Yeah it's more the ledge than the window to be fair, but you're also going to want a bit more clearance between your door + ASHP than would be tolerated with bins.
Just for completeness: in a lot of places, even if you could, you don't want your ASHP outside in easy vandal reach
