Skip advice (uk)

This is UK based please. We live down a road where the houses are all terraced and it's a free for all parking. Our next door neighbour decided to put a skip outside our window (baring in mind there was space outside HER house when they came). She doesn't drive either.

This skip has been outside our house for easily a month and half now, it's full to the brim (almost overflowing). It's also very windy where we live, as we are quite coastal.

What do you think we can do about it? She doesn't answer the door when we knock to speak politely, and we're not the only ones who have complained.
