Lisa, the Co-Director/Secretary has lived in Mandurah since 1970. Geoff has been employed in the Plumbing/Gas Industry since 1983 and migrated to Australia from the UK in 1993 and is a very proud Australian Citizen and often says he lives in the best place in the world… no regrets.

Kelly’s success has been achieved due to the passion and innovation of its very knowledgeable and passionate team members who pride themselves on giving exceptional customer service. Kelly’s endeavor to keep up to date with new products, which enables them to deliver the best products to their customers.

Directors Geoff and Lisa Kelly have taken the approach of working on the business rather than in, which allows the business to achieve its goals.

Kelly’s do various aspects of plumbing but their main passion is hot water, and promote themselves as HOT WATER SPECIALISTS. When the time comes for you to replace your hot water unit please THINK KELLY’S.

Thank you so much to Andrea and the Kelly’s team for firstly servicing our gas heater.

And also for organising the gas to be connected at our property.

Zac did an awesome job connecting it and checking everything was right and also connected our heater.

Thanks again.

Thank you Lisa and Geoff for your fantastic service.

We rang Lisa in the morning as our hot water system was playing up. She sent someone around and it was confirmed we needed a new system.

It was replaced straight away keeping the disruption to the house minimal.

I will definitely be using your company again if needed and highly recommend you to others .

Kellys Hot Water systems where fantastic.

l was not even in the same state and used them to repair my hot water system and communication was very good.

The price did not change from start to finish.

I would recommend Kelly's Hot Water Systems to everyone.

Kelly's were amazing.

We had a warranty job that was submitted with manufacturer.

They said Kelly's would be in contact either that day or the next.

Within 10 mins of my phone call Kelly's were calling me to get our hot water system sorted.

Even went to the extent to try get us a back up for the mean time.

Extremely fast and friendly service.

Some of the best customer service we have ever experienced.

Well done Kelly's! Be proud!

I am extremely grateful they could come and repair my air conditioner as quickly as they did.

This company provides good old fashion service and I would recommend them to anyone.

Big shout out for the service we received from Kelly's.. . our storage hot water system failed and we got an immediate response and help.

Thankfully the advice we received in helping choose a new system has absolutely made the world of difference (temperature, water pressure and economic value) for us.

Thank you so much for your prompt and honest service.. wouldn't recommend anyone else.

Sarah Mears April 10, 2020

Zac was out this morning within 2 hours of making our enquiry. Excellent customer service and advice, Thanks so much Zac!
