No, a Dutch plug does not fit directly into an English socket. Dutch plugs generally have two round pins, while English sockets have three rectangular pins. The pins of a Dutch plug are also slightly thinner than those of an English plug, which is why they do not fit into an English socket.

To use a Dutch plug in an English socket, you need a travel adapter or an adapter plug. A travel adapter is a small device that is placed between the Dutch plug and the English socket. It provides the correct pin configuration and allows the Dutch plug to be safely connected to the English socket.

When using a travel adapter, it is important to pay attention to the compatibility of voltage and frequency. For instance, in the Netherlands, the mains voltage is 230 volts, while in the United Kingdom it is also 230 volts. This means that the voltage is compatible, but your devices may not be designed for the specific frequency of the country where you are using them.

To prevent discomfort or damage to your electronic devices, it is advisable to also use a voltage converter if the frequency does not match. This ensures that your devices receive the correct voltage and frequency and can be safely used.
