I'm moving to the Netherlands, and am arranging contracts etc with a rental agency. They say that an Energy label/energy performance certificate is "not available". My understanding is that the owner is legally required to provide one (https://www.government.nl/topics/energy-performance-certificates-for-homes-and-buildings/epcs-for-buyers-and-tenants), but I'm not going to push super hard unless I have a specific need for it for something else (energy provider, local authority, etc.). Do I need it?
Tenants do not really need this certificate for anything, I certainly never had to present it anywhere. But this is presumably designed to enable you to make an informed decision when moving in. An accommodation with poor energy efficiency could cost you tens of euros a month down the line. And refusing to provide one might suggest the landlord is trying to hide the fact that his property is not terribly attractive from that point of view.
Even with a contract covering energy costs, you have to read the fine print, I once had such a contract but the monthly payments were only provisions to be adjusted at the end of the year, when I was it with a €1500 bill for heating for a rather small apartment.
