Hi yes a nest gen 3 is what I was thinking 

Hi yes still don't understand the wiring as in the earth wire do you go on the wire colour when fitting as I have no labels on any wires do you use the earth wire thanks

Hi thanks for your help going to order one thanks

Hi yes took a look it's says it's compatible only concern I have is my wiring is not labeled I have a red wire and a yellow and a green and yellow thanks

Hi yes tried the compatibility page but as they is no labels on wires wasn't that helpful my compi boiler is a valliant eco pro 28 if that is any help thanks
