Hello, my name's Mark... Welcome to my You Tube channel.I'm a time served Gas Service Engineer, and I've been in the gas, heating and plumbing industry for the last 37 years. My career began in 1979 with British Gas (the proper old one), and has included a vast amount experience encompassing employment as a Gas Safe Inspector (Corgi), Service Technician at VAILLANT, Gas/Heating engineer on LPG (Calor Gas) and too many more to mention.I run a small but highly professional company of associates in the GAS, HEATING & PLUMBING field, based in Central LONDON.I'm also a qualified assessor and lecturer, and when I can find the time, I still train, assess and approve Plumbers in boiler diagnostics and servicing, as well as the ACS gas qualifications at the National Construction College in Erith, Kent. www.intaplumb.co.ukIf you require professional services in the London area, then please feel free to visit our specialist websites, and contact us.Thanks for the visit..
