A Surrey-based invasive plant specialist is celebrating its 30th anniversary this month after growing from a one-man business operating from an attic into one of the UK’s largest dedicated invasive plant management companies.
Environet was founded in 1996 by environmental scientist Nic Seal, at a time when Japanese knotweed was largely unknown outside specialist circles and the risks it posed to property were poorly understood.
After graduating from the University of London with a degree in Environmental Sciences, Seal identified invasive plants as a potential niche within the environmental sector.
Early in the business’s development, he successfully devised a treatment strategy that saved a national housebuilder more than £500,000 on a development site in Wales affected by Japanese knotweed.
INVASIVE SPECIES
Despite recognising the growing threat posed by the invasive species, Seal said convincing others of the problem proved challenging in the company’s early years.
The breakthrough came in 2004 when Environet began advertising its Japanese knotweed treatment services online. A modest investment in one of the emerging Google Ads campaigns generated an immediate surge in enquiries, forcing the business to rapidly expand and recruit staff.
Over the following two decades, Environet established itself as a specialist provider of invasive plant management services, helping homeowners, landlords, developers and commercial property owners tackle issues including Japanese knotweed, bamboo, horsetail and Giant Hogweed.
Today, the company employs 22 people, generates annual turnover in excess of £2.5 million and operates across England and Wales. The business is now fully owned by its employees through an Employee Ownership Trust.
GROWTH SPURT
Nic Seal, founder of Environet, who retired in 2024, says: “We’ve come a long way since the 1990s when hardly anyone had heard of Japanese knotweed and finding chemicals that would kill the plant was a matter of trial and error.
“It’s been incredible to see Environet lead the growth in the industry over the past 30 years, helping homeowners and businesses across the country tackle all kinds of invasive plants with calm professionalism and genuine expertise.”
Emily Grant, Director of Operations at Environet, adds: “It’s been quite a journey from a kitchen table start-up into a national company serving customers in every corner of the UK, whilst staying true to our Surrey roots.
“We can’t wait to see what the next 30 years brings.”
