If you pay a deposit of 2,000 SKK and the bed linen and wood costs are fixed, then it is a bit strange and a rather unlikely coincidence if the variable electricity consumption adds up to exactly 1,000 SKK in costs. Electricity consumption should be made transparent and shown at the beginning and end on the meter, which is not in the holiday home. If I only use half a box of wood, I expect to only be charged for half a box.
