My parents want to start a small home baking business and are planning on getting a commercial oven. Would you guys recommend that we change to three phase?

We have a lot of aircons in the house but pretty much never on them all at the same time. At most 2 on at the same time.

It will depend on your typical load amps right now and what is the supply rating ie 40A or 63A.

That can be checked by an electrician with a clamp meter. As this is done "hot" while electricity is still running.

Generally if the oven is below 3000W then should be no problem.
But if the oven has signs saying "requires permanent installation" or the likes, OR if power exceed 3000W then you still have to pull new wiring as the standard 13A socket is NOT sufficient.

Thanks! I'll get an electrician to check it.

I'll add on - if the oven came with a 13A standard plug will not have issues.

If the oven doesn't come ready-to-use with a plug or requires 415V (three phase), then it will be the first sign of "requires professional installation". Some commercial oven use 415V.

Good to know thanks
