update my light switch to a Smart Switch

Hi everyone, Basically, I am planning to replace the light switches in my new build house with smart switches and as the switch has WiFi built-in it needs constant power to work so will require a neutral wire I've pulled the back of the existing lightswitch and have a "Common" and "L1" 2 x Brown wires in Comm 1 x Brown wire in L1 would anyone be able to let me know if there was a neutral cable installed in the light switch? I have attached photos of them here. I notice the x3 blue cables with a cap on the end, would this be the neutral wire and if it is, will I need to plug all 3 of them into the new light switch? Thanks in advance.

Odd. Those links try and take me to a different forum.

In principle I would say the "blues" need to be kept together and taken to the new wifi switch - not connecting them all together will almost certainly result in parts of the lighting circuit not working.

I too was conducted to an oddly similar Forum .    

As Murdo said , it sounds like you do have neutrals at that switch  , you may not have at ALL the switches . 

I too got directed to another forum. 
what is the cap that you speak of? A link to this? 

you also need to make sure the back-boxes are deep enough for your smart switch.
