Useful answers before you call.

Send clear photographs of the leaves, stems and wider patch. We offer an initial photo identification at no charge, although a site visit may still be needed for a formal survey.

The site location, clear photographs, what you know about the plant, whether the site is residential or commercial, and any sale, mortgage, development or construction deadline are all useful.

Send the site address or postcode, clear photographs, access details and any sale or works deadline. Tell us about nearby water, existing reports and the documents you need.

No. We also work with other invasive plants including giant hogweed and Himalayan balsam. See our Other invasive plants page for more information.

A management plan records the known infestation, relevant site constraints, the proposed treatment or management approach, monitoring and the documentation needed to manage the issue over time.

Yes. We can survey invasive plants, document their extent and site constraints, prepare management plans and provide targeted treatment and monitoring around a development programme. See Land & Development.

Free photo identification is a first step. An inspection starts from £200; a survey with an agreed report starts from £300. Tell us what decision or document you need.

An inspection is required before quoting for a ten-year plan, barrier membranes or excavation. Photos help us prepare but do not replace that inspection.

Treatment visits are every four weeks during the treatment season. The site programme determines timing and suitable work; monitoring forms part of management plans.
