hello i am looking for urgent advice. My heating is not working, we have tried to relight the boiler which is a glow worm hide away 60b using a variety and i think dangerous methods but with no joy. Husband thinks it is the thermo coupling ? and has purchased one at lunchtime today with the intention of fitting it tonight on return from work (does the electric need to be off?) I have also attempted to prepare the kids tea and as i have tried to light the built in hob it will not ignite and furthermore i cant hear any gas either. Is it possible that the bolier and the hob are linked in some way ? or is something completely wrong with the boiler and the hob. The multi point wall heater is ok and working fine. Thank you
