Glyphosate concerns: should you worry, and are there alternatives?

An honest look at the science, the regulation, and what we use when glyphosate isn't the right tool.

We use glyphosate every working day and we take questions about its safety seriously. Here is where the science actually sits in 2026.

The regulatory position

EFSA reviewed glyphosate in 2023 and found no critical areas of concern. The European Commission re-authorised it for 10 years; the UK followed with its own approval. The IARC classification of 'probable carcinogen' remains, but at occupational use levels with PPE the risk is comparable to many household chemicals.

When we don't use it

  • Within 5 m of certain watercourses without an Environment Agency / NRW permit.
  • On certified organic land.
  • On client request — we discuss excavation alternatives.

Alternatives that actually work on knotweed

Mechanical excavation with off-site disposal or on-site burial in an engineered cell. That is essentially the only chemical-free professional option on an established stand. Steam, foam and electric weeders kill foliage but cannot reach the deep rhizome.

What this page can't tell you

  • Guidance is general. Identification, treatment choice and timescales can only be confirmed by a site visit — photographs alone are indicative.
  • Lender and insurer requirements vary by institution and change over time. We state what is typically accepted, not what any named lender will accept on your case.
  • Guarantee (IBG) eligibility depends on the plan chosen, the survey findings and the underwriter's acceptance. It is not automatic.
  • Legal points summarise published law and guidance current at the review date. They are not legal advice.
