Not me personally, but a corgi gas registered gas fitter.
Bit of a long story, but in short, there was no draw on the brick built chimney. I got a chimney specialist out, and he took out everything - box, liner, the lot.
So I now have to fit a new liner, box and all. Before installing a gas fire.
Can you tell me, can the gas fire fitter do this, or do I need another specialist before the gas fitter comes to fit the fire.
