Victoria has been publishing gas-transition plans since its Gas Substitution Roadmap in 2022, and plans can change. What is different now is that the two household-facing dates have been made as building regulation: the Building and Plumbing Amendment Regulations 2025 have been gazetted, with the industry summaries of the gazetted text placing the hot water requirement in Division 3 (sections 45D and 45E) and confirming both commencement dates. A Victorian household can now plan against actual rules rather than announcements.
What the rules require, and when
Victoria's gas timeline, as regulated
| Date | Rule | Who it touches |
|---|---|---|
| 1 Jan 2024 | New homes requiring a planning permit are not connected to the gas network | New builds (in force since 2024) |
| 1 Jan 2027 | All new homes, and new commercial buildings other than industrial, manufacturing and agricultural, built all-electric | New builds and their buyers |
| 1 Mar 2027 | A gas hot water system that reaches end of life and cannot be economically repaired must be replaced with an efficient electric alternative, such as a heat pump | Existing homes, at replacement time only |
| 1 Mar 2027 | Rental properties: end-of-life gas hot water AND gas heaters replaced with efficient electric, plus new minimum standards including ceiling insulation and draught sealing | Rental providers and renters |
Sources: Victorian Government announcement of 24 June 2025 and the SPASA industry summary of the gazetted regulations; the 2024 connection ban per the Premier's 14 December 2023 release. The obligation on existing homes is triggered by the appliance dying, not by the calendar.
What explicitly does not change
The government's own announcement is unusually specific about the boundaries, and they are worth quoting because most of the anxiety about these rules concerns things the rules do not do. Gas hot water systems "can still be repaired if they break down"; systems can be temporarily removed and reinstalled during renovations; "there are no changes to heating for owner occupiers"; and "there are no changes to gas cooking in existing homes". If you own and occupy your home, the only mandated change arrives when your gas hot water system dies after 1 March 2027, at the moment you were buying a new unit anyway.
The claimed savings, attributed
The Victorian Government states that an electric hot water system saves households around $330 a year, or $520 with solar, and that an all-electric new home puts around $880 a year back in its owner's pocket, or $1,820 with solar. Those are the government's own modelled figures from its announcement, not ours: treat them as the case the policy's author makes for it. On the cost side, hot water rebates of up to $1,400 are available through Victorian Energy Upgrades and Solar Victoria, whose hot water rebate (up to $1,000, or $1,400 for a locally made unit, applied after federal STCs are deducted) now carries the tightened $150,000 household income cap that applies to applications from 1 July 2026.
What was dropped along the way
Analysis by RMIT University housing researchers, published in The Conversation, records that the package that became law is narrower than what was floated in earlier consultation: mandatory replacement of all defunct gas heaters in existing owner-occupied homes and mandatory induction cooktops in new builds were both dropped after industry and community pushback. That history is useful calibration in both directions: the rules that survived are the ones above, no more, and claims that Victoria is "ripping out gas stoves" describe a proposal that did not become regulation.
If your hot water system is old now
Nothing requires you to act before your system fails. The practical preparation is knowing what you would buy if it failed tomorrow: heat pump units qualify for federal STC support only if the model is on the Clean Energy Regulator's register of eligible systems (air-source heat pumps up to 425 litres), and the state rebate stacks on top for eligible households. A replacement decision made calmly, with the rebate paperwork understood in advance, will beat one made during a cold-shower week. We will report each future change to these rules as it lands.
