It is currently the bane of my existence and so far the only person who has managed to light it is the plumber who came to fix the hot water… which isn’t even powered by the boiler 
I have attempted multiple times to relight it (we were advised by eon not to leave it on when we didn’t need it as gas is so expensive) and I am sure that I am doing things the exact way he did. It’s one of the very old fashioned ones where you press an ignition switch repeatedly while holding down the button for the gas and it supposedly springs into life.
Does anyone have any magical tips for lighting such things (I can attach a picture but I don’t think it will help) before I swallow my pride and call a plumber out just to light the pilot light?
