Missing power socket in meterbox for fiber

I’ve changed my internet provider from different company to KPN and they installed fiber cable from outside to my meterkast but there is no power socket there. My contract has started yesterday and to test the internet I brought power from living room to there. This was just for trying I do not want to have 5 meters extended cable through my living room to meterkast.

I’ve checked forum and saw examples and understood that KPN should have installed socket to meterkast. Can you help me on that?
