This is dependent on the location that you are living.
In most cases you can find this on the website of your housing corporation.
The costs will be part of the service costs and thus will be in your monthly rent payed to your housing corporation.
When you end your lease contract, it will mean that Internet en Television will stop automatically along with paying your rent.
So no hassle with having to end other contracts, besides your lease of the room.
The only exception to this is Digital Television (DTV). This is a separate service and will need to be ended by your DTV service provider (for example Ziggo or UPC). To end the service you will need your DTV customernumber.
If you have internet and television that isn’t part of your lease agreement, then you probably have a separate contract for internet and television.
If you end your lease agreement , you will still need to end the internet and televison contract.
Otherwise you will keep paying for internet and television.
Having two contracts running usually is more expensive then a combined contract.
