Thanks! I do have a GFCI (aka RCD) at the panel but the lack of grounding is unsettling. If nothing else the Schuko outlet is a lot better at preventing plugs from falling out.
I'll pull an outlet out and have a look for an Earth wire.
Yellow/Green. Sometimes they push them back a bit so it can be hard to spot. Another way to see it is to pull the front off the distribution panel, if you see Yellow/Green from a common rail going into every one of the outgoing tubes then you know it is at least wired up properly. If you only see blue and brown wires going into the tubes except for the ones to kitchen and bathroom then they won't be there. It is possible to pull in a ground wire afterwards but it is quite a bit of work, I've done it, the annoying bit is if there is a pull box that isn't exposed and they made a junction in there, then you have to break stuff to be able to reach the box.
Technically that's illegal but I doubt there is a house in NL that doesn't have at least one or two of those.
Old homes also often have been wired to use radiator/water pipes as ground. This causes a lot of issues now that old, metal pipes are being replaced with modern plastics, which turn a stupidly-grounded socket into a potential death trap.
Also, when there's a light circuit involved, there may be a black wire. In very old wiring situations, you may also encounter red/white/green wires, with green being the live wire rather than the ground!
