A wired dimmable light switch for Uk user

Welcome! :sunglasses:

I suggest you start with the FAQ for UK Lighting; it should answer most of your questions. (This is a clickable link)

@dthomp13 mentioned, many UK members end up using a zwave inwall micro. There are several different brands to choose from. That topic is covered in the FAQ.

If you do happen to have a neutral (blue) wire at your switch box, you will have more devices to choose from, including some all-in-one switches. But that’s fairly uncommon in the U.K., which is why the micros are so popular. Some micros don’t require the blue wire and most can be placed at the fitting, where there will be a blue wire, rather than in the switch box. So they just offer more options.
