The start of Harmuns

“Harmuns came about out of necessity. I ran a property portfolio in London, the South East and in Cardiff and I needed the services of a leak detection company but we couldn’t find one with the expertise or the customer service levels who made us feel as though they cared. They took credit card details up front and in return we got very little, other than being poorer for the experience. Coincidentally, over the years I had built up a great relationship with a number of time-served heating engineers, including some who had worked for other leak detection companies, and so after a lot of research and analysis we decided to set-up Harmuns that puts customers at the heart of what we do.”
