What is a Knotweed Survey?

A knotweed survey is a visual inspection of the entire exterior of a property. It includes:

You can use this survey to give to your chosen remediation company and ask them for a detailed management plan including treatment plans, timescales and costs.

When do you need a survey?

A knotweed survey can be useful at any stage, but it is most important when you are remortgaging, selling, developing, building or hard landscaping property.

What makes a survey valuable?

It is important to know the risks from knotweed and how it can affect you. Because the aggressive growth of the plant can cause catastrophic damage to built structures in its path, if it is present on your property it can pose both a legal and financial risk.

If it threatens neighbouring properties you could find yourself legally liable, while its presence on your own property could make it impossible to sell or raise mortgage finance.

Why is an independent survey better?

A recognisable, standardised set of reporting criteria (in line with RICS guidelines) means you can take our report to any reputable knotweed remediation company in the UK and it will give them the information they need to prepare a management strategy.*
*Please note: if construction works are involved, a more detailed survey may be required.
