The Japanese Knotweed Problem in London
With more recorded cases than anywhere else in the country, Londoners are more likely than most to run into knotweed. Given free rein it grows 10cm a day, splitting foundations, blocking drains, cracking driveways, scaring off mortgage lenders and leaving you liable the moment it crosses into a neighbour’s garden. We know where it hides across the capital, and we deal with it properly.
Here’s why it demands attention:
- Property Damage – It’s strong underground rhizome network (root system) can push through tarmac and can exploit weaknesses in concrete, drainage and weak foundations.
- Value Impact – Lenders often reject mortgages on affected homes, cutting values by up to 10%.
- Legal Risks – you can be held responsible for allowing Japanese knotweed to spread beyond your boundary. Fines reach up to £2,500 for individuals and £20,000 for businesses under the Anti-Social Behaviour, Crime and Policing Act 2014 and in 2018 one company was fined £18,000 in the UK’s first knotweed prosecution. Acting early protects you.
- Environmental Threat – It outcompetes native plants, harming London’s gardens and riverbanks.
- Costly Delay – The longer you wait, the worse it gets, early action saves thousands.
