Word of mouth
Real reviews from real Perth families.
Here are a few of them.
Common questions
Things people ask before they book.
Plain answers, no marketing or sales pressure. If your question isn't here, give us a ring.
How do I know if I should repair or replace?
A few rules of thumb. If your unit is under five years old and the fault is something simple like a thermostat, an element, or a valve, repair is usually the right call. If it’s over ten years old (more than likely out of warranty period), the tank is leaking, or the repair cost is more than half the price of a new unit, replacement makes more sense.
How much will it cost?
Most jobs sit somewhere in these ranges, depending on what you need:
- Continuous flow gas units: $1,800 to $3,200 installed
- Storage gas and electric units: $2,000 to $3,600 installed
- Heat pumps: $4,600 to $6,800 installed (with the STC rebate already applied where eligible)
- Major service every 4 to 5 years: $795 to $980
We walk through the price on site before any work starts. What we quote is what you pay. No surprise extras on the invoice.
Can you actually come out today?
Most days, yes. If you ring before lunchtime, we can usually have someone on site that afternoon. If we’re flat out, we’ll be straight with you and book first thing the next day. We don’t muck you around.
Will you try to sell me a bigger unit than I need?
No. Our reputation is built on the opposite. We work out what fits your house and your family, and that’s what we recommend. If your old 170L unit was working fine for the household, we won’t push you into a 250L just to bump up the price.
What brands do you install?
For storage gas and electric units, Rheem is our most-reliable brand — Australian made, strong tank warranty, sized to suit Perth households. We also service all the major brand (ie. Rheem, Vulcan, Thermann and Rinnai).
We also pride ourselves in being trained to install and service – unlike many of our competitors.
For heat pumps, we install Rheem Ambiheat at the premium end and EnviroSun in the mid-range.
If you’ve already got a unit from another brand, we can almost certainly service or repair it.
How long does a hot water replacement take?
Most replacements take three to four hours from when we arrive on site. So if we get there by mid-morning, you have hot water by lunchtime. Repairs are usually quicker, often done the same visit.
What areas do you cover?
Anywhere within about 50km of Cockburn. Fremantle, Spearwood, Coogee, Beeliar, Aubin Grove, Hammond Park, Atwell, Munster, Henderson, Kwinana, Wellard, Baldivis, Rockingham, Mandurah, Pinjarra, Armadale, Canning Vale, Jandakot and the suburbs in between.
Are you licensed?
Yes. Plumbing licence PL10305, gas fitting licence GF12419 and backflow licence BF7446. All work is checked by licensed plumbers.
What if it leaks again after you have fixed it?
We come back and sort it at no extra charge. Our installation work has a lifetime guarantee. If we replaced the unit, the manufacturer warranty also kicks in (usually seven to ten years on the tank, twelve months on parts).
Storage or continuous flow?
Storage units hold a tank of hot water ready to go. Common sizes for Perth: 125L or 135L for couples and small families, 170L for medium households, and 330L for larger families or anyone who hates running out of hot water in the morning.
Continuous flow heats on demand so you never run out, though the flow rate matters for households with two showers running at once. We’ll talk you through which fits your house on site.
What about heat pumps?
Heat pumps run on electricity but use roughly a third of the power of a standard electric storage unit. Real-world running costs sit around $42 a year if you have solar PV on the roof, or around $246 a year without solar. Compare that to an electric storage unit which can run over $1,000 a year.
The national STC rebate brings the upfront cost down. Rheem Ambiheat sits at the premium end, EnviroSun in the mid-range.
Do you take the old unit away?
Yes. Removal and disposal of the old unit is included in the replacement quote. You will not be left with a busted hot water tank in the side-yard.
How do I pay?
We send you a Stripe link on the day or tap and go, so you can pay by card from your phone. Or bank transfer if you prefer. Payment is on completion, not before.
Will Josh come out, or one of the team?
Either Josh or one of the licensed trademen on the team. Whoever comes out is briefed on the job before they arrive, walks you through the diagnosis, agrees the price with you on site, does the job and will stick around until the install is done and the site is tidy.
What if I'm at work when you arrive?
We’ll text you when the plumber leaves the previous job, so you know roughly when we’re arriving. And when their on the way, live tracking is available too. If you can’t be home, we can usually work with someone else over the phone to walk through the diagnosis and the quote. Card payment over Stripe means you don’t need to be on site to settle up.
What we install & what it costs
We supply and install the best and service all brands.
Three categories cover almost every Perth home. We size the unit to your household, talk you through the options on site, and you decide. No pressure, no upsell.

How we do things
Six values we set on day one. They have not shifted.
Josh started Unrivalled to fix what frustrated him about plumbing in Perth. The dodgy quotes, the upselling, the apprentice left to figure it out alone, the mess on the floor when the boys leave.
The price quoted is the price paid.
We walk you through the cost on site before we touch a thing. What we quote is what you pay. If the job changes mid-way (and sometimes it does), we stop and explain it before any extra work happens.
We tell you straight.
If your old unit can be repaired for a fair price, we will say so. If it is on its last legs, we will say that too. We recommend the unit that fits your house, not the one that fattens the invoice.
We do it once, properly.
Take the time to do it right. Tidy site, neat finish, no callbacks for leaks the next week. Pressure tested, double-checked, signed off. That is the standard, on every job.
We turn up when we say we will.
You get a text when the plumber leaves the previous job. A live tracker so you can see when we are five minutes away. If we are running late, you can get a phone call or text, not a no-show.
We are local and we plan to stay.
Cockburn/Rockingham based, family-run, members of Master Plumbers WA, the Rockingham Kwinana Chamber of Commerce, and BNI. Ring next time a tap goes, you get the same crew that knows your house.
The boys are looked after.
Our plumbers are paid properly, trained properly, and home for dinner with their families. That standard shows up in your house. Tidy work, calm explanations, work you would recommend to a mate.
How a same-day fix works
From the call to the warm shower, here is what happens.
Most jobs are sorted the same day. If you ring before lunchtime, we can usually have someone on site that afternoon.
