Welcome to Mr Combi Training

Installing boilers is fine but the real money is in repairing, there will always be a shortage of breakdown engineers.

Mr Combi Training has taught over 400 installers per year since 2002, including engineers from British Gas, Viessmann, ReactFast, PH Jones, E-ON, NPower, Par-gas, Pimlico Plumbers and many more.

We now offer two courses where you can spend a great day with George Staszak who will help you learn fault finding techniques and understand the cause of common problems with boilers and control systems.

Mr Combi Training is a family run business which aims to provide a friendly and stress free environment where you can learn and develop your skills at your own pace. George will teach you how to test in a sequence using a digital multimeter and manometer. YOU do all the work learning in a great atmosphere! This is a ‘hands on’ day, no sleeping or boring lectures, only guides. Whatever your level, from no experience to advanced, you will be surprised by how much you can learn in just one day.


“This is NOT a day off, lots of hands on!”
