From our customers


Highly recommend you purchase your hot water system from Installed today. I obtained 3 quotes from local plumbing stores and a further 3 quotes from online retailers. Installed today was the most competitive. I ordered at lunchtime and by 9am the next day my new hot water system was delivered. Under 24hrs wow!. The delivery person even wheeled it around to the side of the house for me. Thanks for providing such a competitive price and the fast service was a bonus. You put bunnings, tradelink and Reece to shame.

Sean phoned to confirm what time he would be on-site to remove and install the new Rheem Hot water cylinder. He arrived on time and set about removing the old cylinder and installing the new . He worked non stop with the installation which was completed to a very high standard. He cleaned up any mess and after loading the truck he ran through the install showing me what did what and if I had any problems to let the company know. It was good to see a conscientious tradesman at work.Thanks Sean, a great job

Josh and Brandon arrived on site and explained what they were going to do. Took minimal time to do the job and explained the warranty and maintenance procedures before they left. They gave me peace of mind by stating they would return within the 10 year warranty period if any trouble occurred with the system. I found both boys to be polite and courteous and took the time at the end to show what was replaced and how to operate it. From start of the booking process at 7:30 am to the completion of the job at 3:00 pm the same day,
