Welcome to Mr Combi Training

George Staszak has taught over 4000 installers and engineers per year since 2002. This includes engineers sent directly by British Gas, Viessmann, ReactFast, PH Jones, E-ON, NPower, Par-gas, Pimlico Plumbers and many more. Along with our courses, we have also worked very hard to bring a range of extra products such as our apps which are there to help or support engineers.

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.

Why should you come on a course?

We have a jam packed set of lessons in the mornings on both our courses where we cover everything we think you need to do better in your jobs and make more money. The Heating Engineering industry in the UK covers a big set of subjects across three domains: gas, water and electricity.

We also have shelves of parts, including pumps, fans, switches, sensors and stats, which are there to be tested by you on the day. In the afternoon you’ll spend your time doing some testing on actual boilers or controls rigs so you can take the knowledge you’ve learned in the morning even further.

Along with all this training you’ll get the following benefits:

  • Spend time practising on real equipment, using your own multimeter.
  • Learn at your own pace and focus on the things you need to get from the day.
  • Learn how to move from installing to breakdowns. There’s a lot more money to be made in repairing boilers and systems.
  • Access to George Staszak, Mr Combi himself, who has over 50 years experience in the industry and still attends factory courses to learn new things he can pass onto his students.
  • The opportunity to ask your questions about issues you’ve had in the past or suggestions for new ways to tackle a job in the future.
  • A friendly atmosphere where you can chat with other Heating Engineers from all across the UK about their experiences or discuss some of the topics covered on the course. We often hear students sharing tips with each other and business cards get exchanged regularly.
  • Both our courses are backed up by our bumper course notes for you to take home and reinforce your learning from the day. There’s some extra helpful stuff in there about subjects we just don’t have time to cram into our courses.

One of the more common comments we get from students on our course is about their confidence. We have students from a wide range of backgrounds and levels of experience, even the more capable students seem to get a surge of confidence by the end of the day.


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