2019 update
Two new devices are now available in the UK.
Neo coolcam makes both single gang and double gang UK style Glass switches which some community members are using. These models are Z wave, not Wi-Fi. They will connect directly to SmartThings.

And Phillips now has new designated partners who are creating switches that harvest the kinetic energy from the finger push (like the Hue tap), so they require neither batteries your wiring. Neither batteries nor wiring are needed. But you must have a hue bridge. They will definitely work with lights which are connected to the hue bridge.
It’s not clear yet whether they will be visible to smartthings, though, or whether you will be able to use them with the smartthings hubs directly once the hubs are updated for Zigbee 3.0. We will just have to wait and see on that. But if you have a lot of Hue bulbs, it will be a nice alternate means of control. Without having to worry about batteries or pressing an extra time to wake up the device .
