annual costs

Hi all,

We are currrently paying 27 euro per square meter fixed costs (coverin in fact all costs, electricity, syndic,...) that per our contract can be raised with 1,5 % each 3 years.  but now we received a letter that due to the exceptional situation in 2022-2023 (inflation, energy costs exploding, lack of snow) they are forced to raise this to 33 euro per square meter.  We wonder if we can challenge this raise ? Anybody who was in similar situation ?

Thanks!

Glen
