Hi, my corgi registered gas fitter has just informed me that I need my chimney lined as their is a problem between the ground floor and the 1st (failed the smoke bomb test miserably!) He's quoted £325 to install the liner which call me tight seems a lot of money? Companies on t'internet will sell you the liner for around £16 per metre, but I'm guessing you need 'other bits' as well? With not knowing anything about chimney lining, could somebody please tell me whats involved in doing this job and if £325 is a reasonable price for it? Many thanks Carl.
