Japanese knotweed specialists in Liverpool

Guidance from Liverpool City Council

• The council covers knotweed within its general guidance on private housing rather than on a dedicated page.
• It states that property owners must control knotweed and repair any brickwork, render or other structures it damages, and suggests legal advice where a party wall is affected.
• The council refers residents to GOV.UK guidance on invasive plants and does not offer treatment for private property.

Further information is available on the council's website: Private sector housing issues.

Local background

• In late 2025 Liverpool City Council awarded a contract worth about £25,800 (excluding VAT) to excavate and dispose of knotweed from the site of the planned new Princes School. (source)

The law in England

It isn't an offence to have Japanese knotweed on your land, but under section 14 of the Wildlife and Countryside Act 1981 it is an offence to plant it or otherwise cause it to grow in the wild. Government guidance says you must stop it spreading off your property. Soil or plant material containing it is likely to be controlled waste, which must only go to an authorised site, and councils can use community protection notices where someone's failure to deal with it unreasonably affects people nearby.
