The FAQ gets added to all the time with new posts in that thread, so as long as you’re reading the whole thread you should be up-to-date. 
As far as UK options, there are a number of choices. Not so many all-in-one switches as there are in the US, but there are a couple of brands as long as you have a neutral wire at the switchbox (in the UK that’s the blue wire).
However, even if you don’t have a blue wire at the switchbox, there are still options. One of the most popular is to use one of the in wall Micros, like Fibaro, Aeotec or Qubino. Some models do not require a neutral. These go behind the switch, so you can use a large variety of switch styles with them. These are available both as on/off switches and as dimmers.
Have you had a chance to look at the UK lighting FAQ? There’s a lot of information there.
There are also a number of existing threadS from UK members discussing various specific lighting projects. Some are in the UK section of the forUM and some are under projects.
@anon36505037 has done his whole house with Fibaro lighting and can probably answer more specific questions.
