No. All-in rents do not provide insight into your basic rent, nor into your advance service costs. As a result, you do not know what you are paying for, how much you should get back from your service costs, by how much your basic rent has been increased annually, …
The Rent Tribunal is strict about this. Via a procedure Splitting All-in rent, they will split this into: 55% basic rent, 25% service costs and 20% automatic reduction. This means that you will pay 20% less after your split anyway. In addition, we can check immediately whether the new basic rent (55% of the old All-in price) is not too high either. This can all be done in one procedure, so definitely worth it!
