What business owners say
"After countless refusals from other plumbers I managed to get hold of Aiden and he DID NOT DISAPPOINT … My cafe grease trap was pouring out everywhere, and within 45mins he was there. In the end he completely solved the issue and even cleaned afterwards."
Tim Dacey, café owner, Google review
"Aiden was very professional and on time to the job. Got it done and dusted faster than I expected."

No hot water at your business? Here's what's at stake
In hospitality, hot water isn't a comfort. It runs the dishwasher, the hand basins, the cleaning down and the coffee machine rinse. When it stops, you're looking at a kitchen that can't wash up properly, staff who can't clean down, and a hygiene problem you can't serve through.
Most owners ask the same three things: can you get here before we open, what's it going to cost, and can you work without shutting us down? We answer all three on the phone, before the plumber leaves.
If you can't trade without hot water, it's not something to leave till Monday. Call and we'll tell you straight how soon we can get someone there.
How we fix commercial hot water: assess, explain, approve, fix
Assess. Your plumber finds the actual fault, a failed element or thermostat, an ignition fault, a tempering valve, a leaking tank, rather than guessing.
Explain. You get a plain-English rundown of what's failed, why, and what your options are. If a repair gets you trading today and a replacement can be planned for a quieter day, we'll say so.
Approve. We give you one clear price for the job. Nothing starts until you approve it, and no hourly meter ticks while we work.
Fix. We repair or replace the unit, then test the hot taps, temperature control and safety valves before we leave. We clean up after ourselves, because your floor is your workplace.
What we repair in cafés, restaurants and small businesses
We work on all makes and models of the hot water systems common in small commercial premises:
- Gas storage systems: pilot and ignition faults, thermocouple problems, gas safety checks, leaking tanks
- Electric storage systems: failed elements and thermostats, tripping power, slow recovery
- Continuous flow units: error codes, ignition faults, lukewarm water at low flow
- Valves: tempering valves for scalding or fluctuating water, and relief valves that won't stop dripping
- Leaks: from the tank, fittings or pipework
A straight note on larger plant. If your site runs a large commercial setup, a boiler or a bank of linked units, tell us when you call. We'll tell you plainly whether it's within our scope, and if it isn't, we'll point you to the right specialist rather than turn up and waste your morning.
Who we help
- Cafés and coffee shops: early starts, small kitchens, one unit doing a lot of work
- Restaurants and takeaways: dishwashers, hand basins and cleaning down between services
- Pubs, bars and venues: kitchens, staff amenities and public bathrooms
- Small offices, clinics and shops: staff kitchens and amenities that need to work
- Insurance-related work: we've handled insurance work, so we're used to explaining clearly what was found and what was done
Working around your trading hours
We know a plumber in the kitchen mid-service is the last thing you need. Tell us your opening time, your busiest window and where the unit is, and we'll plan the visit around it as best we can.
If the fault can be fixed on the spot, we fix it. If a part needs ordering, we'll tell you the timeframe up front and whether there's a safe way to keep you running in the meantime. And if anything is outside plumbing, say an electrical fault beyond the unit, we'll tell you, and recommend the right trade.
Commercial hot water system replacement
Sometimes a repair isn't the right call. A tank leaking from the base usually can't be repaired, and an old unit with parts failing one after another tends to keep costing you.
When replacement makes more sense, we'll explain why and price the options. We look at how much hot water you actually use, what utilities you have on site, and the long-term running costs, then safely disconnect and remove the old unit, install the new one, and test and commission it. More on hot water system replacement.
Pricing for commercial jobs
We charge by the job, not by the hour. Your plumber assesses the system on site and gives you a clear price before any work starts. You'll know the cost before you commit, and there are no surprise line items at the end.
What moves the price: the system type and brand, whether the part is in stock, access (a unit above a cool room or in a cramped back store takes longer), and whether it's a repair or a replacement. See more on hot water repair cost.
How it works
- Call 1800 571 216. Tell us your business, suburb, the system type if you know it, whether it's leaking, and when you open.
- Get advice and a plumber on the way. We'll tell you what to switch off, if anything, and keep you updated on the ETA.
- On-site diagnosis. Your plumber finds the fault and explains your options.
- You approve, we fix. One clear price, then the work. We test everything before we leave.
Commercial hot water questions
Can you get to us before we open?
We dispatch immediately for urgent jobs and give you ETA updates on the way. Exact timing depends on your location, demand and the weather, so we'll give you a realistic estimate when you call.
Do you work at night or early in the morning?
Yes. We're open 24 hours, 7 days, including weekends and public holidays. An after-hours visit before opening is often the easiest way to avoid disrupting service.
What does a commercial hot water repair cost?
It depends on the fault, the system and the parts. We charge by the job, not the hour, and you approve the price on site before we start.
Will you push us into a new system?
No. We diagnose first and only recommend replacement when repair isn't practical or cost-effective. If the tank is leaking, replacement is usually the only real fix, and we'll show you why.
Do you work on large commercial boilers?
Tell us what you've got when you call. We'll tell you straight whether it's within our scope, and if it's not, we'll point you to the right specialist.
Can you work around our staff and customers?
Yes. Tell us your trading hours and busiest times when you book, and we'll plan the visit around them as best we can.
Do you handle insurance-related hot water work?
Yes, we handle insurance-related work. We'll explain clearly what we found and what we did, which helps when you're dealing with your insurer.
Can you fix it today?
Often, yes. We aim for same-day repairs across most Melbourne suburbs. If a part has to be ordered, we'll tell you the timeframe before you decide.
No hot water and you've got to open? Call now.
Whether it's a café, restaurant, venue or small office, a licensed OnCall plumber can diagnose it, price it, and, once you say yes, fix it.
