Running a Hog Roast Company and trying to find a Gas Fitter that has an LPG qualification is not easy. A search on the internet and I found Gasco Plumbing and I cannot believe its now the 3rd year that I have used Mark to service and certificate my Hog Roasting Machines, The first time he looked at my machines, then only two Mark scratched his head and said "well this is a first" I had ordered some parts for him and he was soon taking covers of and opening up the to the gas valves, and soon the one that need fixing as working, The next machine was serviced and the flame increased by 30%. Mark has come out every time I have needed him and yearly turns up to do the yearly certifications. I would recommend Mark for any job especially any one with Hog Roast Machines as he now has them on his CV Good Luck Mark going forward
