Check Wiring Diagram for Nest Dual pls

[abc_plumb]

Hi Fellow Engineers

I've attached a wiring diagram I've just completed, I wanted to make sure I've got it correct.
Looking to install 2 Nest thermostats to a Worcester combi boiler.
1 Zone is radiators and the other is UFH, with pump on manifold

Would be grateful to receive feedback.
Thanks

Yes correct you can feed the wiring centre from Ls on the boiler if you want

I assume that would mean the boiler needs to turn off to power off the wiring center?

Yes or via the fused spur
