The summer of 2025 has been one of the warmest and driest on record in the UK. In this latest blog, we investigate the impact of invasive plants in our ever changing climate.

If you’ve discovered Japanese knotweed on your property, acting quickly and decisively is essential. Tackling the problem with professional help is not just the most effective route – it’s the most responsible one.

With the launch of KnotSure™, our new desktop report, property professionals and homebuyers finally have a fast, affordable way to understand the knotweed risk at any UK address, using real data and expert insight – ahead of committing to an on-site survey.

Invasive non-native species (INNS) pose significant threats to our native ecosystems, outcompeting indigenous flora and disrupting wildlife habitats. While managing existing invasives is crucial, proactive measures to promote native biodiversity are equally important.

In this blog, we explore how invasive non-native weeds affect native wildlife in the UK and why early intervention is key to protecting our fragile ecosystems.
