Agree, had us a goose chase up til nowNone of it is looking very logical - might this wireless stat perhaps have nothing at all to do with the system? Might there be no stat at all, or even a wired stat on the wall somewhere?

From under the boiler there is a cable going up to the left.
Where does that go to?

Will a plumber be up for sorting out a new wireless thermostat or do I need an electrician ?
Difficult one - not all plumbers are electrically competent and not all electricians can cope with controls. Your are really looking for a Gas Safe guy who is familar with controls wiring.
Have you tried moving the stat closer to the area where you guess the receiver is?
Yup, tried it near the boiler and the cylinder. Will be (mildly) interesting to see if it works in the morning…
In your pics you show a 2 port zone valve for the HW you must have one for the CH also, the receiver will be connected to that
