I would not recommend this business, paid double what I should have for a new hot water service, then was told we had a gas leak which could cost upwards $7,500 to have fixed. I sought out a second opinion to find there was no issue with our gas pipes etc. Our regulator was removed from our cooktop by Metropolitan plumbing as this was the likely cause of the so called leak. When the second opinion plumber went to hook up my cooktop he found my regulator to have been taken so I needed to buy a new one through him. (at a very reasonable rate).
Only positive was they were very quick to attend the property. I had to chase the receipt for services provided and the compliance note also.

Approximate cost: $4239
