Best gas installation services in Perth metro

These are the 15 Perth metro businesses where gas installation and gas fitting sit at the core of the work, ranked by an earned composite score (see our methodology). Scores last updated 5 October 2026.

Businesses that only dabble in gas work are left out. If you want a general plumber, see our best plumber overall list. The order here follows the composite score, which weighs rating, review volume, recency and review sentiment, so close scores mean very little separates two businesses.

Picks are ranked by score and relevance to gas installation service, so a lower overall score can rank higher here.
