The history of GlenFarrow

Take a look back through our company timeline over the last 50 years.

    1972 | Glen Heat & Irrigation

    Glen Heat and Irrigation (GlenFarrow’s original business name) was formed in Spalding, Lincolnshire. “I realised there was a gap in the market for the smaller types of irrigation works. All the big firms at the time were too big and not too interested in the smaller jobs that farmers and growers wanted.” – Managing Director, Mr Gilbert Maddison

    1980s | Glen Heat & Irrigation expands

    The company was going from strength to strength in the services it could offer. A major development for the company came in the late 80’s when a local irrigation company, Farrow Irrigation, were looking for a buyer. Farrow Irrigation then became Farrows of Spalding – a division of Glen Heat and Irrigation.
