About the Knotweed Company

The Knotweed Company was founded in 2010 to answer a need for a professional contractor who had the knowledge and skills necessary to control and eradicate Japanese knotweed and other invasive weeds in England and Wales. The Knotweed Company meets the urgent needs for the highest level of professional service that today's expectations demand. Uniquely, we avoid sensationalism and scaremongering, and can combine the necessary knowledge, experience and skills to control and eradicate Japanese knotweed and other invasive weeds effectively and safely, whilst recognising the importance of understanding related environmental concerns and having the knowledge to provide workable solutions that take these extraneous issues into account.

The Knotweed Company proudly contributes to and helps develop Best Japanese Knotweed Control Practices in England and Wales. We have a Head Office in the Midlands, a Regional Office in the South of England and several Regional Operatives based throughout England and Wales.

Brian Taylor – Managing Director

Based at our Head Office in the Midlands, Brian Taylor is our founder and Director. He has gained considerable experience of working with invasive weeds over a career lasting over 25 years. Even as a schoolboy, he spent his summer holidays working at the Weed Research Institute. Since then he has studied and gained the following qualifications:

  • NPTC PA1, PA6aW Safe Use of Pesticides
  • MSc in Crop Protection
  • Higher National Diploma in Amenity Horticulture
  • Diploma of Management Studies
  • Institute of Safety & Health - Managing Safely
  • Site Supervisor Safety Training Scheme (SSSTS)
  • Certificated Surveyor in Japanese knotweed (CSJK)

Additionally, he is a member of the BASIS professional register and can advise on pesticide use within the Amenity Horticultural sector.

Since 2004, Brian has worked almost exclusively with Japanese knotweed and the associated hybrids. He has successfully managed knotweed eradication from Tyneside to Penzance and from Anglesey to Dover. Brian has an impressive background in working with construction companies all over the United Kingdom, in identifying the most appropriate solution for each site and in managing and/or supervising the works. He is a member of the Property Care Association's Invasive Weed Core Group and, as such, has contributed to the creation of the PCA CSJK and QTJK examinations. He occasionally serves as an examiner for the CSJK qualification.

Brian is proud to say that he has experience in managing all proven types of knotweed eradication strategies including full excavation and removal from site, on site burials, stockpile (bund) methods, reduced level excavations and herbicide programmes. He is fully qualified to apply herbicides and still enjoys a day out spraying!

Jim Glaister – Regional Manager

Jim Glaister joined The Knotweed Company in July 2013 to run the Hampshire office as Southern Regional Manager. He has been dealing with Japanese knotweed and other invasive weeds since 2004. As well as writing a number of articles on the subject, he has provided a variety of presentations to environmental consultants, mortgage advisors, county councils and organisations such as RICS (Royal Institute of Chartered Surveyors) and the PCA (Property Care Association). He provides CPD training on invasive weeds, especially Japanese knotweed, and is a contributor to the RICS subscription online information portal 'isurve'.

He is qualified to undertake the herbicide treatment of Japanese knotweed, holding both the PA1 and PA6aW NPTC qualifications, and has gained the CITB qualification on the Site Supervisor Safety Training Scheme and an Institution of Occupational Safety and Health (IOSH) qualification in Managing Safely.

He was one of the first people in the country to take the Certificated Surveyor in Japanese Knotweed (CSJK) course run by the PCA and the first to pass the exam with Distinction, winning the PCA Student of the Year Award in 2015 as a result. Since passing the exam, Jim has joined the roster of examiners and markers for the CSJK qualification.
