Going All Electric in Geelong: What the 2027 Gas Rules Mean for Your Home's Wiring

Victoria’s move away from gas stops being a headline in 2027 and starts showing up in Geelong homes. New homes will be built without gas. Broken gas hot water systems can’t be replaced with gas. And rental properties face even stricter rules.

Most of the conversation is about appliances. The part people miss is the wiring. Every gas appliance you swap for electric adds load to a switchboard and supply that, in a lot of older Geelong homes, was never designed for it.

This guide explains exactly what the 2027 rules require, who they apply to and what going all electric means for your switchboard, circuits and power supply, from a Geelong electrician’s point of view.

Quick answer: Victoria’s 2027 gas rules in brief

1 January 2027: New homes and most new commercial buildings in Victoria, including knock down rebuilds, must be all electric. No new gas connections, except in specific circumstances.

1 March 2027: Gas hot water systems can no longer be installed in existing Victorian homes. When one breaks and can’t be repaired, it must be replaced with an electric alternative, such as a heat pump or electric boosted solar.

1 March 2027 (rentals): Rental homes must also replace failed gas heaters with efficient electric heating, plus meet new cooling, insulation and other standards.

Not affected: Existing gas heaters and gas cooktops in owner occupied homes can keep being used, repaired and replaced.

Wiring impact: Electric hot water, reverse cycle heating, induction cooking and EV charging add significant load. Many older Geelong homes need a switchboard upgrade, new dedicated circuits, or a supply upgrade.

Savings: The Victorian Government estimates existing all electric homes save about $1,900 a year, or $2,230 with solar.

What are Victoria's 2027 gas rules?

Victoria’s 2027 gas rules are a set of building, plumbing and rental regulations that phase gas out of new homes and gas hot water out of existing homes. They’re part of the Victorian Government’s Gas Substitution Roadmap and are phased in from 1 January 2027.

If your building permit was approved before 31 December 2026, you may still be able to connect a new home to gas. After that, new homes won’t be eligible for a gas connection.

Do the 2027 rules apply to my existing Geelong home?

It depends on whether you own and live in the home, rent it out, or are building new.

If you own and live in an existing home (Highton, Belmont, Ocean Grove, Torquay, Lara and so on):

Hot water: yes. From 1 March 2027, if your gas hot water system breaks and can’t be repaired, or needs replacing for any other reason, it must be replaced with an electric alternative.

Heating: no. There’s no requirement to replace existing gas space heating. You can keep using, repairing and replacing it.

Cooking: no. Gas cooktops can stay.

Renovations and extensions: you can stay connected to gas, keep using existing gas appliances and even extend gas to a new part of the home.

If you rent out a property in Geelong:

The rules are stricter. Failed gas heaters and gas hot water must both be replaced with efficient electric systems from 1 March 2027. We cover the detail in Gas heater or hot water died in your Geelong rental? and our rental electrical compliance guide.

If you’re building new in Geelong’s growth areas:

From 1 January 2027, new homes must be all electric. That includes knock down rebuilds in established suburbs like Belmont or Newtown and new detached buildings on the same block, such as a granny flat or a large shed.

The short version: hot water is the one change that reaches almost every Geelong home. Gas hot water systems typically last around 10 to 15 years, so a large share of local homes will face this decision within the next few years.

What going all electric adds to your home's electrical load

Gas appliances use almost no electricity. Their electric replacements do the same job with electricity, which means more current through your switchboard, wiring and supply. Here’s what each swap typically involves electrically:

Swap

Typical electrical demand*

Usually needs

Gas hot water to heat pump

Around 1 to 1.5 kW running; some models have a booster element of up to around 3.6 kW

Dedicated circuit and isolator; option to run on a timer or midday solar

Gas wall heater to split system (reverse cycle)

Around 1 to 3 kW, depending on size

Dedicated circuit, outdoor isolator

Ducted gas to ducted reverse cycle

Around 4 to 8 kW or more for a whole house system

Larger dedicated circuit; sometimes three phase power

Gas cooktop to induction

Up to around 7 kW with all zones on full

Dedicated circuit, often 32 A cable from the switchboard

Petrol car to EV (home charger)

7 kW single phase; up to 22 kW three phase

Dedicated circuit, load management, often a switchboard check

Gas oven to electric oven

Around 2 to 3.5 kW

Dedicated circuit

Indicative ranges only. Actual demand depends on the model, size and settings and an electrician will calculate your home’s maximum demand before adding circuits.

One appliance on its own is rarely a problem. The issue is stacking them. A home that adds a heat pump, two split systems, an induction cooktop and an EV charger over a few years can end up asking far more of its supply than the original wiring was planned for.

That’s why we recommend planning electrification as a whole, even if you do it one appliance at a time. Ask once: what will this home’s switchboard and supply need to carry in five years? Then build towards it.

Will I need a switchboard upgrade or three phase power?

Not always. But in Geelong’s older suburbs, it’s common.

Signs your switchboard isn’t ready for an all electric home

Ceramic fuses instead of circuit breakers

No safety switches (RCDs), or only one RCD covering a few circuits

No spare space on the board for new circuits

Asbestos backing board (common in boards installed before the late 1980s)

Breakers tripping when the kettle, heater and oven run together

Scorch marks, buzzing or a warm board

Any of these mean the board should be assessed before adding a heat pump, split system or induction cooktop. Our switchboard upgrade service covers replacement with modern circuit breakers, RCD protection on every circuit and room for future circuits.

Single phase vs three phase in Geelong

Most Geelong homes run on single phase power. That’s usually enough for a heat pump, a couple of split systems, an induction cooktop and a 7 kW EV charger, especially with smart load management.

Three phase power is worth considering if you plan to:

  • Install large ducted reverse cycle heating and cooling
  • Charge an EV faster than 7 kW, or charge two EVs
  • Run a large solar and battery system alongside heavy electric loads
  • Add a workshop, pool heat pump or spa

Upgrading to three phase involves your electrician and the local distributor, which in Geelong is Powercor. It takes time, so it’s best decided early rather than when an appliance has already failed.

Why older Geelong homes need extra care

Weatherboards in Geelong West, Newtown and Drumcondra, post war homes in Belmont, Hamlyn Heights and Bell Park and 70s and 80s brick veneers in Highton, Grovedale and Corio often still have original wiring and switchboards. Some have old rubber insulated or undersized cabling that shouldn’t carry extra load at all.

If that sounds like your home, an electrical inspection before electrifying is money well spent. Our residential electricians can assess the whole installation and give you a staged plan. Planning a kitchen or bathroom refresh? Do the electrical upgrades as part of your renovation while the walls are open.

Building new in Armstrong Creek, Mount Duneed, Charlemont or Lara?

If your building permit is issued from 1 January 2027, your new Geelong home will be all electric by law. That’s a big opportunity to get the wiring right from day one, instead of retrofitting later.

Before lock up, ask your builder and electrician about:

Switchboard size. Allow spare space for at least 6 to 8 future circuits.

Three phase supply. Cheaper to get at the build stage than to add later, especially if you want ducted reverse cycle or fast EV charging.

EV charger circuit. Even if you don’t own an EV yet, run the cable to the garage now. Our EV charger installation page explains what’s involved.

Induction cooktop circuit sized correctly for the cooktop you actually want.

Heat pump hot water placement away from bedroom windows, with its own circuit and timer or solar control.

Solar and battery readiness. Conduit from the roof space to the switchboard and space for a battery.

Outdoor power and lighting. Extra weatherproof power points and garden lighting are far easier before landscaping.

We work with owner builders and builders on new build electrical work across Geelong’s growth corridors, from Armstrong Creek and Mount Duneed to Charlemont, Lara and the Bellarine.

What does going all electric cost and what rebates are there?

The Victorian Government says efficient electric appliances can cost no more than gas alternatives once discounts and rebates are applied. Here’s what’s available for Geelong households (as at October 2026):

Incentive

What it covers

Amount

Victorian Energy Upgrades (VEU)

Heat pump hot water, reverse cycle air conditioning, induction cooktops, insulation and more

Hot water discount up to $560; other amounts vary by product

Solar Homes hot water rebate (Solar Victoria)

Heat pump or solar hot water for eligible households

Up to $1,000, or up to $1,400 for an eligible locally made product

Combined hot water support

VEU + Solar Homes together

Up to $1,560 off a new efficient hot water system

Small scale Technology Certificates (federal)

Heat pump and solar hot water, solar panels

Applied as a point of sale discount

Cheaper Home Batteries Program (federal)

Home batteries installed with solar

Roughly 30% off; reduces every six months, with the next step down in January 2027

Solar Homes rebates have eligibility rules, including a household income cap, so check Solar Victoria before you buy.

What you save afterwards: Victorian Government figures put the saving from replacing gas hot water with electric at around $400 a year and an existing all electric home at about $1,900 a year, or $2,230 with solar. Going fully electric also means you can drop the gas connection and its daily supply charge altogether.

The cheapest way to electrify is to bundle work: one switchboard upgrade and several circuits in a single visit costs less than three separate call outs.

How to go all electric in Geelong: a step by step plan

Not every home needs every step. A single conversation with an electrician turns this into a plan that fits your budget and timeline.

Frequently asked questions

Is Victoria banning gas in existing homes in 2027?

No. Existing homes can stay connected to gas. From 1 March 2027, the change for owner occupiers is that a failed gas hot water system must be replaced with an electric one. Gas heaters and cooktops can stay.

Can I still replace my broken gas hot water system with gas after March 2027?

No. From 1 March 2027, gas hot water systems can’t be installed in Victorian homes. A failed unit must be replaced with an electric alternative, such as a heat pump or electric boosted solar.

Can I still get gas connected to a new home in Geelong?

Only if your building permit was approved before 31 December 2026. From 1 January 2027, new homes, including knock down rebuilds, must be all electric.

Do I need a switchboard upgrade to go all electric?

Not always. Homes with a modern circuit breaker board, RCDs and spare space often don’t. Homes with ceramic fuses, no RCDs, a full board or an asbestos backing board usually do.

Do I need three phase power for an all electric home?

Most Geelong homes run fine on single phase power. Three phase is worth considering for large ducted reverse cycle systems, fast or dual EV charging, or heavy workshop loads.

Does a heat pump hot water system need its own circuit?

Generally yes. It needs a dedicated circuit and isolator and can be set up to run on a timer or during the day on solar.

Do I need an electrician for an induction cooktop?

Yes. Induction cooktops usually need a dedicated circuit, often with 32 A cabling. A gas cooktop never needed one, so most kitchens converting from gas need new wiring.

How much can I save by going all electric in Victoria?

Victorian Government figures estimate around $400 a year from replacing gas hot water with electric and about $1,900 a year for an all electric existing home, or $2,230 with solar.

What rebates are available in Geelong?

Hot water upgrades can attract up to $1,560 through VEU and Solar Homes combined. VEU discounts also cover reverse cycle air conditioning and induction cooktops. Federal programs support solar and batteries.
