Thanks for your replies guys. Yes it will be next to the current CWS tank, i think t-ing it across to feed it is the best way. I couldn’t get my head around how it’d work with calling for and shutting the ballvalve off to the new f&e but that makes sense. Yeh the current set up is definitely wrong that’s why customer got in contact with me. Will soon have it sorted, thanks for your help.

The CWST fill valve only controls the pump so yes, there will be some pressure at the F&E ballcock (the same as if you were supplying it from the mains) with the pump running, but you won't be dead heading the pump because when the CWST float valve is satisfied, the pump stops.

It's not a fill valve onthe CWST, it's a switch as in the original post. I think your suggestion is the way to go. The inlet to the CWST needs to be higher than the F/E tank inlet, but that should be the case anyway.
