Cold showers are not something you should have to put up with. We handle hot water repairs and replacements across Mandurah for electric, gas, and heat pump systems. You get honest advice on whether a repair makes sense or if replacement is the better long term option. Everything is explained clearly before work begins. The result is simple. Hot water that works when you need it.
A burst pipe can soak walls, floors, and ceilings in minutes. We act fast to isolate the leak, stop further damage, and stabilise your plumbing system. Once things are under control, we fix the underlying cause properly so you are not dealing with the same issue again. You get straight answers and a repair you can rely on.
Get three quotes then go with Kelly’s. Kelly’s sponsored our bowling club so I wanted to give them a go. I like companies that put back into the community. I needed to replace an old storage water heater with an instantaneous hot water system. To be on the safe side I got three quotes, all providing the same unit. Kelly’s was the best by a long way. And I do mean a long way. Literally hundreds of dollars. Each company said I would need a new gas pipe. Two said they would run it alongside the wall. Kelly’s came and pulled up a few bricks and buried it. No extra charge. All up, totally brilliant. Highly recommended. I like having hot showers again. Thanks guys.
Roughly 2 years ago we had Kelly’s Hot Water supply install a new hot water unit. They did an excellent job. About a month ago we had a new underslung sink with a new tap. the existing pipe work & waste pipes took up a heap of room in the cupboard. I rang Kelly’s to see if the could sort it for us, without hesitation the answers was yes. One of their tradesmen came around to have a look, his reaction was that yes we can do it and I will be back tomorrow with the parts I need to sort your problem. Sure enough Tim came back as promised and a couple of hours later he had finished. What a great job he did, we now have a lot more room in the cupboard and a very neat set of pipe work. Thank you Kelly’s & Tim for a job very well done. If we ever need plumbing done again Kelly’s will be the first number we ring.
Perth’s most honest and reputable plumbing company. Quality service, quick response time and knowledgeable staff. Many thanks to owner Lisa and her professional tradesman Ian who came out to fix a few things. I was stress crying in the early morning and by mid morning my heart felt like a weight was taken off my chest, 25yrs in the industry speaks volumes about this WA owned company. A old saying comes to mind “a good trade is never out of work” so I’ll be spreading their name around like the plague! You must call Lisa and her team and experience the same amazing service & save your money!
Had our hot water system not working this morning, rang another company was told the unit will need replacing “too technical to repair” was the answer. Rang Kelly’s.. Was told nothing is too technical or not replaceable, they were out within the hour!! went out of there way to organise another appointment to fit ours in as we were not home in the afternoon, they had our hot water system all sorted by lunch. Lovely staff and professional tradesman. A great local business truly recommend Kelly’s hot water gas & air. Keep up the great work guys. Positive Responsiveness, Professionalism
I was so impressed with the service I received that I had to leave a positive review. I called at 9.30am on a Monday, hoping to be able to get someone out to fix a leak at some time during the week. I was given 12-2pm that day and when I asked for a phone call 15 minutes prior to arriving to ensure I could leave work , that was no problem. I received a call at 12.55pm, raced home to find Zac waiting patiently. He identified the issue and fixed it within no time and I nearly fell over when he said the price, in a good way! I was expecting to need to donate a kidney to pay for the repair and it was actually as cheap as chips. Zac was lovely, gave some good advice for future and was on his way in a flash. It is becoming so rare to get good quality service at a reasonable price but I definitely received that. Thanks Kelly’s, I’ll be calling you first time every time now.
Kelly’s Plumbing are an outstanding, professional organisation. We just had a leaking pipe under our paved driveway. I dug up the sand and they were on site within an hour of making the call. I spoke to Lisa and she moved heaven and earth to accommodate us. Ian was the plumber on site, he was was quick, professional and polite. This is the second time Kelly’s Plumbing have reacted to urgent plumbing issues to our house and have provided a 100% solution that day both times. Considering this was an hour turn around from making the call, the price was more than reasonable, bordering cheap. I cannot recommend Kelly’s Plumbing enough.
2025- Have to update my review as we needed to call Kelly’s again. This time our hot water system started leaking. They came and saw us, answered all my many questions and installed a new system in just a few days. As always helpful, knowledgeable and a great price. 2024, From start to finish the team at Kelly’s were informative and wonderful. We had Zac come out as our old taps seemed to be leaking. He checked them all over and sourced the filters needed (not typical size as I’ve had issues with other taps) Zac returned and fixed all our leaking shower taps and also installed a new outside water tap. Informative, helpful, well priced, family business, friendly staff. All boxes ticked!
Awesome company to deal with! Our hot water system died on Sunday and I contacted Andrea at Kelly’s Hot Water first thing Monday. Andrea sent me a quotation a short time later on Monday morning and after swapping a few jobs we had our new Rheem water heater installed this afternoon (Monday) The installer Regan was friendly and knew what he was doing and we couldn’t be more happy with the service received from the staff at Kelly’s Hot Water. We had some advice from Kelly’s a few years ago and our dealings were excellent then. I wouldn’t hesitate to recommend Kelly’s Hot Water. Well done team..John
Our Tuesday morning took a surprising turn when our hot water system failed, but a swift message to Lisa sparked a rapid response. After a prompt callback, I dropped the grandkids off at school and returned to find a service technician providing quotes and expert advice. We selected the ideal system and contacted Andrea in the office to book the installation for the next day. The team was courteous, informative, and even removed the old unit, leaving us thoroughly impressed with Kelly’s Hot Water & Gas. We would highly recommend them to anyone. Thanks to Lisa & all the team for your wonderful service. Denise & Mike

We fix the problem properly, clean up after ourselves, and make sure everything is working as it should before we leave.
Hot water is our bread and butter. We diagnose issues fast and recommend fixes that make sense for your home and budget.
You are dealing with real people who live and work locally. We treat your home the way we treat our own.
Plumbing problems do not wait for business hours. We are available day or night when things cannot wait.
We explain the issue, your options, and the cost before work begins. No jargon and no pressure.
You know the price before we start. No hidden extras and no awkward surprises at the end.
Our workmanship is guaranteed for life. That means real peace of mind long after the job is done.
Blocked drains are rarely just a surface issue. We locate the cause, clear it completely, and restore proper flow through your system. This prevents smells, backups, and repeat problems that waste time and money. You get drains that work properly, not a short term fix.
Poor water quality affects everything from drinking to showering. We install water filtration systems designed for Mandurah households and local water conditions. The result is better tasting water, healthier use throughout the home, and less strain on your plumbing system.
Heat pumps are an efficient hot water option when installed correctly. We size and install systems based on how your household actually uses hot water. That means consistent performance, lower running costs, and fewer issues down the track.
Bathroom renovations fail when plumbing is treated as an afterthought. We plan and deliver clean, compliant plumbing that keeps your project on track. No shortcuts. No last minute surprises. Just a bathroom that works as good as it looks.
If something is leaking, blocked, or not working the way it should, now is the time to act. We’ll give you straight advice and a fix you can rely on.
10/10 service. Amazing. Highly recommend. I realise at 6.45am on Monday morning my hot water system is broken. I call the service at 8.00am. Before 10am I have had one service person at my property confirming that I need a new hot water system. A second person arrived with the hot water system for installation and everything was sorted by 11.45am the same morning. This was superior service. Thank you. Melissa F
I’ve used these guys a couple of times and they don’t disappoint. Fast, fair and professional. Yesterday my boiler died. By this afternoon I was having a hot shower. What’s not to like?
We received a huge water bill, showing we were losing more than 1,000 litres of water a day. Called Kelly’s and they sent us a plumber within an hour. He solved it in 5 minutes and did not charge us. I just love working with these guys, they are quick, professional and genuinely there to help their clients when they are in trouble. Thanks Kelly’s!
They’ve done good work and a great service
A very BIG thank you for the amazing service. Our hot water system broke and Kelly came to our rescue and within a couple of hours of calling we had a team on site to install a new system. Outstanding service from the call being taken to the system installed, thank you. Highly recommend this company as we have always had a great service.
I had a fast response when Zac came over and quickly identified the problem with the control valve. Although he didn’t have the necessary part in stock, he returned the same day to fix the issue. Good bloke and we are extremely grateful for his efficient service. I would highly recommend Kelly’s to everyone. Thank you so much Kelly’s.

Great service, highly recommended
Really fast turn around from inspection to complete replacement under warranty for my Rheem hot water. Polite and efficient workmanship. Thank you heaps for getting us back up and running so quick.
Me and my folks have used Kelly’s Hot Water Gas and Air a few times over the last decade or so for various things. Always genuine, professional and friendly. Definitely recommend to call Kelly’s first and also save them to your phone under plumber, so in an emergency you know who to call! With 20 years in Business they must be doing something right!
Amazing service from the team! Great communication & speedy service. Thanks for your quick response, order & install of our new hot water system. Much appreciated!
Kelly’s Plumbing replaced our failing Hot Water Service quickly and efficiently. Price was good and would highly recommend.
Thanks to Lisa and her team for getting us out of a bind on a Sunday morning. Great communication and fast response, super helpful in a stressful moment. Great work team …
terrific job! thought this was gonna be a headache, the lads tested some stuff and pressed some buttons, said this thingy is the broken part and fixed it without me needing to understand fractal geometry. Thank you! .-D
Fantastic customer service, fast turn around. Have used them before & very happy. 5 stars easy

Geoff at Kelly’s is so approachable and accommodating. Friendly professional service provided by not only Geoff but his staff. I have had two houses fitted with gas facilities and appliances and have never had any issues or problems. Very well priced and quotes always offered and supplied. I can’t recommend Kelly’s highly enough! Don’t even hesitate to give them a call.
What can I say, absolutely amazing service. We had Geoff out many moons ago when Kelly’s was new to Mandurah. I was so impressed with the respect he showed in our home, by putting booties over his shoes to come in the house. Well nothing has changed! We had a water leak, and Lisa pointed me in the right direction with a leak detector person and then Regan, their son, came and fixed the leak the same day. So wonderful to have trades in our community who do a great job are so personable too. Thank you so much to the whole team at Kelly’s Hot Water and Gas .-)

When I found out that my Mum had an issue with her hot water system, Kelly’s was my first call. Despite being fully booked and short staffed, within a matter of hours Zac came out, identified the issue, replaced the faulty part, and had the hot water back up and running. Boy did Mum enjoy her steaming hot shower tonight on this cold May day! Thank you, Kelly’s. Five stars for service, professionalism and price ☆☆☆☆☆

I fully commend Kelly’s Hot Water, Gas & Air Service. Had to have them out due to a failure in our Gas Hot Water System and they were prompt and very efficient. Thanks to Andrea in the office who kept us informed and Regan for the workmanship on site.
A big Thank you to Kelly’s plumbing for replacing our boiler, & fixing our leak!! You saved the day. Great Price Great service. Wouldn’t go anywhere else! No need to chase around for quotes….This local honest family business is the only one you need to rely on.
We had sold a rental property and 2 days from settlement I found the hot water system not working. Rang at lunchtime and Tim arrived earlier than I was told. He quickly diagnosed the issue which necessitated a replacement unit. Lisa in the office was able to rearrange Tim’s schedule to enable the install that afternoon. He was very particular in how the job was done. Workmanship was first class. Highly recommend these guys.
3 year old instant hot water system sprung a leak on the heat exchanger, Andrea and her team and the manufacturer came to the rescue with a new unit. Excellent workmanship cannot fault the installation.
Feared our gas water heater had finally given up the ghost, but a cleaned water filter later and the water pressure is better than it ever was! Knowledgeable serviceman, answered all our questions about the pros and cons of future replacement. Top Notch service from Kelly’s, cannot recommend highly enough…
Had Zac come out to our holiday home in Rockingham during the week. Great bloke and knew exactly what the problem was and fixed it with a minimum of fuss. The whole experience from start to finish was pleasurable and efficient. Would recommend Kelly’s to anyone needing their services. Very happy

Thanks for the great service Andrea & Regan! You guys were fast, friendly, professional and efficient, and took the time to help us with choose a replacement system that was right for our needs, and even fixed a problem we didn’t know we didn’t know we had. Thanks for a great experience.
I had a gas hot water heater stop working on Friday, they came out to look at it, I knew it needed replacing and they had it replaced and working by that afternoon. Great service, nice people to deal with and couldn’t ask for better service. Price was on point too. Recommend them if you need a plumber. Thanks guys!
