The Netherlands uses 220 volts at 50hz and the UK uses 230 volts at 50 hz. So as long as you use a 230 volt light bulb in your UK home the fixture will work perfectly. It can handle the extra 10 volts.
Wire nuts
A light that is mounted on the ceiling.
Normally red or black is the hot wire and green is the ground. However someone may have used the green wire as the neutral wire which is normally white. Just connect the black wire from the light to the red wire and the white wire from the light to the green wire and see if it works. If not you have to pull the wires out of the ceiling box and see how they wired it.
If you connect the ground wire to the hot wire it will trip the breaker. If you get the white and black wires reversed it will still work but does not meet code.
By earth wire I am assuming you mean the bare wire and that a black and white wire are connected to the light. If when you connect the earth wire and breaker trips then there is a short between black and earth. It could be a bad ground connection, an internal short in the light fixture where black wire "hot" is connected to metal on the fixture through a nick in wire.
You connect it with the same hot wire as the black wire in the fan. It is intended to be tied to a different switch. One for the fan, and one for the light kit.
Open up the ceiling box and disconnect the blue wire coming from the light and connect it to the black wire coming from the fan. Be sure and put a wire nut on the wire where the light was connected before you removed it. The wall switch is controlling power to the wire where the fan is connected so when you connect the blue fan wire to that connection you will be sending power to both the fan and light from the wall switch.
Dome light
Some ceiling fans have a black, white and sometimes blue wire. The blue wire in this case is so you can switch a light separate from fan. If your fan doesn't have a light just put a wirenut on extra wire and ignore it. If you do have a light and want it switched you'll need an extra wire run to fan, and switch that wire for light.
