Switching from gas to induction cooking – step by step

Let’s walk through the actual process step by step.

There’s two ways you can approach it: The grand transformation, or slow and steady.

Option A – The grand transformation

This is the process you want to follow if you’re committed to upgrading from gas to induction and want the most efficient order to do things.

Step 1: Confirm the cutout size for your existing gas cooktop

The easy way – look up the model number

If you can find out the model number for your gas cooktop, you can look it up. There will usually be specifications on what size cutout it fits. If you live in a newer apartment, you might have an owners manual for your unit that tells you all the models of the appliances that were installed. 

The lazy way – estimate

Usually, you won’t usually be able to see the cutout underneath your cooktop.

But what you can do is grab a tape measure and measure the full width and length of your cooktop, and the subtract a few cm as to get an estimate of the size of the hole the cooktop is sitting on. 

This can be a bit risky as you don’t know the actual size. However, when the plumber removes your cooktop later, you’ll be able to confirm.

The hard way – measure it yourself 

You might be able to look into the kitchen cabinet under the cooktop and see the cutout.

Most of the time, you’re going to need to remove things that are in the way so you can get a look. Taking out a few drawers is simple enough but in some case, you might need to remove your oven.

Step 2: Check your pots and pans

Are they induction compatible? What size are they? It’s helpful to get an idea of whether you can use your existing ones or whether you would need to buy new ones.

Step 3: Find a cooktop you like

You’ll want to find an induction cooktop you like that’s of a similar size to what you’re currently using.

If you can’t find the same size (within a couple of mm), it’s usually easier to get an induction cooktop that needs a slightly larger cut-out as your installer can cut your benchtop. 

If your benchtop is wood, it’s pretty straightforward to make the cutout bigger. If it’s marble or granite, you’ll need a stonemason to come in 

Step 4: Get quotes 

Once you’ve decided on a cooktop that you like, now is the time to get quotes so you can make a final decision.


Different induction cooktops draw a different amount of power and your electrician will need to make sure the circuit they install can handle it. Usually, you’ll need 32A. 

They’ll also need to see your existing switchboard and understand the layout of your home so they know how easy or hard it will be to run a new circuit to your induction cooktop. 

Gas plumber

Disconnecting and decommissioning a gas cooktop is a pretty straightforward activity, and most of the time it will cost between $250-$300.


If you need to make the cutout in your benchtop larger, then you’ll need to get a quote from a stonemason. 

Step 5: Buy cooktop & organise installation

If you’re ready to commit – then order your new induction cooktop and get it delivered!

Once that’s there and ready, you can start organising for people to come around.

Remember that the order must be as follows

  1. Gas plumber comes first to disconnect
  2. If needed, stonemason comes second to cut the hole and prepare for installation
  3. Electrician to install new cooktop and required electrical upgrades. 

If you don’t need a stonemason, it’s common that the gas plumber and the electrician can come on the same day. 

Option B – Slow and safe

If you want to take smaller steps and get a feel for induction first, here’s the order you should follow.

Step 1: Get portable Induction

A lot of people start out by using this as a way to test out induction cooking to see if they like it, and how well it works with their existing pots and pans. IKEA has some great affordable options.

Induction cooktops also come in portable form that plug into a regular power socket. However, they will be less powerful, and you might only get 1 or 2 burners. 

Keep in mind that a proper induction cooktop will be much more powerful. 

Step 2: Get quote from an electrician

Costs can vary a lot depending on your situation, so even if you really like induction cooking, it’s worth getting quotes so you can decide whether you want to commit to upgrading your kitchen

Step 3: Disconnect gas & confirm cutout size 

If you’re committed to induction, then the next step is to get a gas plumber to come decommission your old gas cooktop so you can get rid of it.

You’ll also be able to confirm the exact size of the cutout in your bench.

Since you’re already cooking with your portable induction cooktop, there’s no rush to get install your new cooktop on the same day as getting your gas cooktop removed.

Step 4: Find a cooktop you like and buy it

Self explanatory!

Step 5: Install new cooktop

Since your gas cooktop is already disconnected and gone, all you need is to get your stonemason to come in (if needed), and then get your electrician to install the new cooktop.
