Quick answer: the best time to post on Instagram for plumbers is the hour your own followers are most active, which Instagram Insights shows under your audience. Published charts average other accounts. Emergency work and bathroom renovations are not the same audience, and not the same clock. Check your own numbers, or use a scheduler that reads them.

The person with a burst pipe is not browsing Instagram for your best hour. The person planning a bathroom is. If the feed is renovations, Insights for that audience is the chart. If the feed is emergency proof, Facebook and Google Business Profile do more than a timestamp.
What practitioners generally see is that local trades get looked at in the evening, when the homeowner is standing in the room. Convention. Your own Most active times wins.
On a professional account, Insights under Your audience has Most active times by hour and day. That is your patients, clients or guests - not a national average. Instagram moves the menu; start at your profile and look for Insights or Professional dashboard.
Write down the top slot for the days you actually post. Check it again in a couple of months. It drifts.
A new page, or one that only posts the van wrap, has no chart. One finished job a week, suburb in the first line, in a slot you can keep from the ute. Then read Insights.
Stories for the same-day job, if you want them seen today. Feed for the finished bathroom. Reels of a walk-through travel past followers, so the hour is secondary.
From your own Instagram history: when your followers have engaged with your posts before. It needs enough posts to see a pattern, so on a brand-new account it uses a sensible default until your numbers arrive, then switches.
On the review screen you can publish now, pick a time, or choose "schedule for best performance". Most people choose the third and stop thinking about it, which is the point.
The job is the post. The suburb in the first line is the targeting. The hour is a setting. Stock pipes at 9am will not book a bathroom.
