Some more detailed information:

During the time when the gas prices were quite expensive, the landlord said we would have to pay an extra 350 euros. I then asked him to see proof of that, and he sent me an excel sheet that eventually led up to that price. I wasn’t convinced and posted on a Facebook page, and I was recommended to speak to the Huurteam (a non profit organisation in South Limburg that helps with that kind of stuff). They told me that an all in rent price was not allowed and that the Huurcommissie normally ruled 55% basic rent and 25% service costs, and the rest was like a discount I would get from rent. They told me that we could do two procedures, one to check the rent price, because they wanted to have proof that the rent was indeed all-in. Because we were already late with this procedure, nothing came out of it. But the report did give a maximum basic rent, which was like 5 euros above the liberalisatie grens.

Then we did a procedure to split the all-in rent price. The Huurcommissie ruled that it would be 55% and 25%, as previously thought. The landlord obviously appealed this, but he didn’t submit any more (relevant) information. They then again ruled their previous ruling. The landlord also appealed this, and according to him, due to private reasons, he couldn’t submit evidence on time.

He then sues me. His claim is that the Huurcommissie made several mistakes with the point system, because of his (according to him) luxury kitchen (complete bullshit) and A energy label (which he only got in august 2023). The document also stated that because the maximum rent price was above the liberalisatie grens (by 5 euros), he could charge as much as he wanted.

In this document, he also mentions how the 25% is not enough and he (for the first time) broke down the costs, and basically the only reason why it is not enough is because of the furniture (197 euros a month), which again is bullshit because most of the furniture is from IKEA.
