Our Journey

Our journey started in 2003 when Michael Farnsworth joined forces with his business partner Lisa Farnsworth to create Stormsaver.

Having developed a natural passion for water conservation during his time at Nottingham Trent University, Michael pioneered some of the first commercial rainwater harvesting systems in the UK.

We’ve come a long way since 2003! From 2 people working out of a garden shed, to a highly sustainably office and production facility in the heart of the Nottinghamshire countryside. Lisa and Michael are joined by 36 talented team members who are the beating heart of Stormsaver and the reason why so many of our customers return to us each year.
