Ratcliffe College

66% reduction in consumption per pupil
Keltek highlighted that there was a constant flow of 1,2000 l/hr of consumption even when the school was empty. They promptly and efficiently located the leak on a 100 m section of pipe and through slip line technology were able fix the leak with minimum disruption and save us £12,000 per year. I would thoroughly recommend Keltek

Havas Helia

An absolute pleasure!
I would just like to pass on my thanks for your attentiveness this last week. Your team were an absolute pleasure to have on site and were very helpful and kept us informed at all times. If we need further works done in the future I would not hesitate to use your firm as it is a rare thing to find such customer care, particularly in the industry in which you work. They have left the site cleaner than they found it to be honest and all works have been carried out with care. Thank you so much, this has been a bit of an ongoing saga for us as you know so to have it sorted is a huge relief.
