Our water tank was overflowing and wouldn't stop. I rang Hennellys and got a professional response. Kevin attended within the hour - he was courteous, respected our home, explained the work and pricing before starting. He worked very efficiently and showed me what he'd done and why. I'd recommend Hennellys with confidence.

I woke up to no hot water or central heating and the response to my phone call was very quick, efficient and reasonably priced. I would recommend this company to others.
