Quote to add zone to HW/CH system

My CH and HW currently cannot be turned on or off independently and there is no room thermostat either. It’s a vented gravity fed system - I’ve been quoted 2.1k to do the following:

New nest wireless controls Full zone pack for heating 2x valves wiring center cylinder stats Extra pipework to cylinder Extra wiring to cylinder full rewire of heating system at boiler and controls

I’m assuming this is a non-DIY job so this may be my only way unless I manage to get other quotes but getting someone out to quote is very difficult.

Does this price seem ok?
