What senses the gas when the pilot ignites to allow the main burner igniting, that was / is my concern.

you get flame recognition across the electrodes ac currant coming from the pcb when rectified across the electrodes go back to pcb dc currant

Hi, just an update, I waited until my regular boiler repair man came back from holiday so he's just been this morning.

It was a blocked injector which he's cleaned up and got it working again, he's also serviced it as it was due one.

Great price too, barely more than he charges for a normal service
