Made up of 3300 extra nebenkost and 300 other costs. 150 of which was a cracked knob on the shower. So be careful what you take responsibility for. What you think is a CHF20 repair will almost certainly be not. My agent was being nice as he put it by only charging me 150. The repair is not being done and the 150 was by way of compensation for the damage.

I took over a lease that was 2 years old and the nebenkost was a poultry 125 a month on a 160sqM flat. So the nebenkost akonto was already not enough. Add to that buying oil when it was double the price now and I have a big bill to pay.

Having seen the nebenkost breakdown and the oil purchases I had no argument on the cost of oil and I was arguing about the small things. And for the sake of a couple of hundred francs I put it down to experience and moved on.
