If your pressure (bar) is now OK and you have made sure the programmer is on for CH only + your room thermostat is calling for heat then it could be the motorized valve is faulty and needs looking at.

Thermostat turned up and timer on constant?
Yes, still nothing. Looks like the boiler does not kick in, no reaction to switch on on the thermostat. Before it was lighting the fire up and heating was on, where now is nothing. What else can it be?

Maybe it is then as everything else seems to be in place including pressure on boiler now :(

Yep needs the motorised valve/s checking out.
Maybe thermostat broke hmm or that valve you're saying. Is there any way of opening the motorized valve manually? Just trying all the options before calling in plumber as I know it can get very expensive... Just found one youtube video. Will try to move the level on motorized valve back and forth, maybe it'll kick off again.

Dependant of what valve you have. Turn the thermostat all the way up. Put the timer on for heating only. Get someone to stand by the boiler whilst you force the manual lever over on the valve at speed. See if the boiler does anything when you do this. Other then that. Registered engineer time mate.
