There are two good battery operated options if you are using smart bulbs.
The simplest is just to get the Phillips hue dimmer switch. This allows you to turn a group of bulbs on, off, or dim. Works very well, but not everyone likes the look. We use these at our house, and have been very happy with them.
Another alternative for the UK is to get the popp or zwave.me battery operated wall controller. Each of the four corners can be depressed, which gives you multiple controls. Some UK members have created a box or blanking plate to put this over an existing switch. This looks very nice, but costs more then the Phillips.

One of the project threads on building the Popp into a blanking cover:
The Z wave.me, popp, and devolo switches all use the same device handler. They typically cost around £40. Each of the four corners can be depressed independently so you get multiple functionality. These are only available on the UK zwave frequency.
We should note that the battery operated options cannot directly control the current, so they can only be used with devices that are independently connected to the network like Smart bulbs or pocket sockets or in wall relays. But they do give you an intuitive on-the-wall option for control.
Have you had a chance to look at the UK FAQ for lighting control yet? It covers most of the wired options.
