I spent 20 years doing up houses and moving up the ladder, my cousin was a time served heating engineer and showed us the basics to install ch systems, and he commisioned my first boiler (before corgi apppeared). I moved to devon 8 years back and ran a bb, prior to gutting it and turning it into flats and a house for the wife and kids. During the refurb which took 18 months for 3 flats I started a 6129 level 2. Then i took a year off to finish my place and a final flat (did most of the work myself hence the long timescale, but only had the bank to keep happy and no real pressure). Then went back to college to do a level 3 6129 and quickly knocked out nvq 2 and 3 using my flats and outside work I was doing at this time, for on site evidence. During the final year at college I used the rgi I had commisssion and installed my flat boilers for works experience required for acs quals. Did the acs exams in my final year at college, signed up with gas safe and tiddly ho off we went. The best bit being a lot of the customers who i had worked for doing small plumbing jobs had all been awaiting my gas quals and I have been installing a steady number of boilers for them since then. Be assured being nice to your customers whilst you are training pays dividends when you have all your tickets. Be assured that no matter how much experience you get during training, it never seems enough and you will always be learning, cultivate any contacts you get with other rgis as they are your best source of help when stuck wondering why the boiler in front of you still wont work when you have tested every last bit of it.
See guys I can be a positive little plumber (can I get sarcastic now? its more fun!!!)
