Obviously the immersion heater is ok so we can ignore that, but you need to check the fuse in the spur box marked 'central heating'.
This one supplies power to the heating programmer on the wall and if you can't get any lamps to come on there ( and the spur fuse is good) then I would guess the fault is within this, rather than the boiler unit.
Once the programmer plays ball, the top lamp on the boiler will glow red and then we're in business!
