Knotweed and controlled waste: what the law actually requires
EPA 1990, Wildlife and Countryside Act, Hazardous Waste Regulations — what each one says about moving knotweed soil.
Knotweed waste is one of the most heavily regulated soils a UK contractor handles. The penalties for getting it wrong include unlimited fines and, on commercial cases, custodial sentences.
The relevant law
- Environmental Protection Act 1990 — duty of care for waste, transfer notes, licensed disposal.
- Wildlife and Countryside Act 1981, s.14 — offence to plant or cause to grow in the wild.
- Hazardous Waste (England) Regulations 2005 / equivalent in Wales.
- Anti-Social Behaviour, Crime and Policing Act 2014 — Community Protection Notices for knotweed nuisance.
What this means in practice
Soil containing live rhizome cannot go in your domestic green bin. It cannot be tipped on a neighbouring field. It cannot be added to a public composting site. It must be moved by a licensed waste carrier and disposed of at an authorised facility, with a transfer note retained for two years.

What this page can't tell you
- Guidance is general. Identification, treatment choice and timescales can only be confirmed by a site visit — photographs alone are indicative.
- Lender and insurer requirements vary by institution and change over time. We state what is typically accepted, not what any named lender will accept on your case.
- Guarantee (IBG) eligibility depends on the plan chosen, the survey findings and the underwriter's acceptance. It is not automatic.
- Legal points summarise published law and guidance current at the review date. They are not legal advice.
