What a lad. Out of all the people that came to quote our cooktop swap, he was the only one that really went into the detail needed to find out all the nitty gritty details and recommend the full course of action.
Turns out the electric hot plate currently there was hard wired, so we needed to get a sparky out. He called up a friend for us and referred.
In doing the work, he took the time and care required to meet all the certifications and standards conferred him by the relevant bodies. Not only that, but he insisted in a basic clean up of the area affected when done.

He quotes a very reasonable price for the work done.

I'll keep this guy on speed dial for any future plumbing/gas jobs.

Approximate cost: $avg
