We have recently moved into a rented property, It’s a maisonette and we are downstairs. When we moved in we were told both the front and back gardens were ours. (I’ve checked again and defo ours) The upstairs neighbour has so far put ladders on the lawn, cut things over the lawn and left bits in the grass, popped up ladders randomly in front of the downstairs windows in the garden, frequently walks past the windows to put things on the lawn (there is no reason to be in front of the windows it’s not on the road and it’s not a pathway to his front door) has mown half the lawn - not the other half as that had the random bits in it and clearly didn’t want to mow the missiles that would create. We have a strong suspicion they have entered the rear garden to wash their windows - being ground floor the back garden is where our bedroom windows are. before I go round and ask him to give us a bit of privacy in our own home - I just want to check if I’m being unreasonable in feeling they need to ask. They have seen me cutting the bushes, refilling bird feeders etc so it’s not like it’s a miscommunication. It’s just bothering me I have no real privacy.
