House Sharing Problems

Hi Guys,

I moved into a house share a few months ago and it seemed fine at first but now I have encountered some problems. I come home from work all the time and my housemate has left his dishes on the sink once again and not cleaned them. The first few times I saw them I just put them in the dishwasher but now out of principal I am choosing not to do it anymore. I am not his parent. I was thinking to do up a rota of chores so that everybody in the house will make an effort to clean the house, I do not want to have to do it all the time but I think this might be a bit much. He is not very approachable.

As well, I do not have any bills in my name in the house as I am the last in the house, when we are paying bills I never get to see the bill.

Does anybody have any advice on how I could solve these issues without causing tension in the house please?
