Buying or selling a home is already a major financial undertaking, but if Japanese Knotweed is found on or near the property, it can introduce serious complications. This invasive plant is notorious for its rapid growth and potential to damage structures, and it’s a red flag for many mortgage lenders. In this blog, we’ll explore how Japanese Knotweed mortgage problems arise, how they can impact your property transaction, and what steps you can take to resolve them effectively.
What Is Japanese Knotweed and Why Is It a Problem?
Japanese Knotweed (Fallopia japonica) is a fast-growing, bamboo-like plant introduced to the UK in the 19th century. It thrives in a variety of environments and spreads aggressively through its root system (rhizomes), making it extremely difficult to eradicate without professional help.
The main concerns for mortgage lenders include:
- Structural Damage: Knotweed can exploit weaknesses in concrete, tarmac, and brickwork.
- Rapid Spread: It can spread to neighbouring properties, increasing legal and financial liabilities.
- High Removal Costs: Eradication often requires long-term treatment plans and professional intervention.
How Japanese Knotweed Affects Mortgage Applications
Mortgage lenders in the UK take Japanese Knotweed seriously. If the plant is found on or near a property, it may lead to:
- Mortgage Rejection: Lenders may refuse to approve a mortgage until the issue is addressed.
- Down-Valuation of the Property: Surveyors might reduce the property’s market value, affecting loan-to-value ratios.
- Requirement for a Management Plan: Lenders may insist on a Knotweed Management Plan backed by an insurance guarantee before processing the mortgage.
The Role of the RICS Risk Categories
The Royal Institution of Chartered Surveyors (RICS) has established risk categories to help surveyors assess Japanese Knotweed:
- Category 1: No knotweed on the property or within 7 metres.
- Category 2: Knotweed on a neighbouring property, within 7 metres.
- Category 3: Knotweed on the property but more than 7 metres from habitable space.
- Category 4: Knotweed within 7 metres of a habitable space or boundary.
Mortgage lenders are especially cautious with Categories 3 and 4, often requiring a professional treatment plan before progressing.
Selling a Property with Japanese Knotweed
Sellers are legally required to disclose the presence of Japanese Knotweed on the TA6 property form. Failing to do so can result in future legal action. If Knotweed is present, the following steps can help mitigate mortgage-related issues:
- Arrange a Professional Survey: A detailed site survey from a qualified consultant like CYB Environmental will assess the extent of the infestation.
- Implement a Management Plan: This should include a treatment timeline, monitoring plan, and an insurance-backed guarantee.
- Maintain Clear Documentation: Keep records of all assessments and treatments to provide to potential buyers and lenders.

- Request a Management Plan: Ensure the seller has a treatment plan in place with insurance backing.
- Use a Specialist Mortgage Broker: Some lenders are more accommodating if proper measures are in place.
- Consult a Professional: CYB Environmental can help with assessments, treatment, and liaising with lenders.
