Wow! What service.
Problem solved.
It's getting warmer already :D .
Thanks for your all your advice - it was the overheat stat had tripped.
Again thanks to you all.

I have an Ideal Classic FF350 boiler which just stopped lighting up. One minute it was ok the next it just "died".
The electric power is on, the gas is on, the room stat and timer are all ok but the boiler just wont light.
Should there be a pilot light visible through the viewing window...
