Discover if Japanese knotweed is present in your area of the South East by checking our Japanese knotweed heatmap.

This is the UK’s only interactive, regularly updated knotweed map – it’s just part of our ongoing research into the effects of this plant. Ideal if you are buying a home in the area – to identify potential risk and threats to your mortgage application.

We’ve already charted thousands of identified infestations of Japanese knotweed – but we can also offer a detailed, site-specific survey that can also determine the likelihood of Japanese knotweed rhizomes being present, hidden in the soil.

Not surprisingly the Environment Agency describe Japanese knotweed as the UK's most aggressive, destructive and invasive plant.

We’ve been successfully removing it for 23 years. Our expert team can resolve your knotweed problem – so don’t believe all the scare stories you’ve read in the press.

All of our work comes with a 10-year insurance backed guarantee, underwritten at Lloyd's. This means you can trust us to do the job well - and nearly all banks and building societies will trust our guarantee as a security for making you the mortgage offer you need.
