Hello All
I am new to the Home Automation Scene and looking at getting my first system, I want to change all plug sockets / light switches and maybe even heating in the future, ideally want it to work over a phone all and Amazon Echo, I have been doing some research and seems to be that LightwaveRF and Z-Wave seem to be the main two (sorry if I am wrong!)

what system do people recommend and suggestions on what to go for?

after some research I have picked up that Z-wave works on a matrix system and Lightwave is a wi-fi but nothing more , I am from the UK and seems very limited on the light switches due to no neutral.

many thanks
