Happy Clients

John Munro

Brian has installed two hot water systems for me and also carried out general plumbing work on my house. I have always found him to be punctual and friendly with a good sense of humor. His work is top quality and his prices are very reasonable. I highly recommend Brian Knock / Advantage Hot Water

Emma Vaughan

Advantage Hot Water provides an excellent and affordable service. He arrived on time, was professional and was very reasonably priced. I will certainly be using this business again for future plumbing works.

Christopher Stanley

My hot water was not working so I called Advantage Hot Water and asked for an emergency call out. Brian Knock attended promptly examined my hot water system which was approximately 5 years old, identified the problem and offered his advice. I quickly researched the problem on the internet and discovered the advice Mr Knock had given me was the most cost effective way to rectify the problem. I took his advice, he fixed the problem and I had hot water that afternoon. I found Mr Knock to be a down to earth, no nonsense and honest trades man who completes his work to a high standard of quality. I would not hesitate to recommend Brian Knock and Advantage Hot Water to any of my friends and associates.

Isobel Moyle

Unfortunately my Water Heater had a problem. Not knowing who to call I looked up the yellow pages and found Brian Knock’s advertisement. Seeing he has been in the business for over 40 years I rang him, this was at midday Thursday and he was at my home in the afternoon to check my heater. It had to be replaced and he returned next morning Friday at 8.30 am to install the heater. ( You don’t always get that type of service). I found Brian to be a very pleasant, reliable gentleman and would have no hesitation in recommending him to my friends.

Kellie and Scott Westwood

We couldnt be more grateful for your promptness with your initial visit getting our very old system up and working again for us till we could get the new one installed. Your down to earth manner makes it very easy for us to recommend you to anyone needing your services. Thank you again.
