    Biosecurity Auditing

    Biosecurity Auditing

    Independent, evidence-based audits of whether contractors working across your estate, port, utility network or rail corridor are actually following the biosecurity protocols they signed up to, not just whether the paperwork says they should be.

    Contractor Compliance Audits

    Unannounced and scheduled site audits checking wash-down, PPE hygiene and movement control in practice.

    Method Statement Review

    Assessment of contractor RAMS against real invasive species and biosecurity risk on your sites.

    Estate-Wide Audit Programmes

    Rolling audit schedules across multi-site estates with a consolidated compliance dashboard.

    Port & Marine Biosecurity Audits

    Auditing vessel, container and quayside biosecurity controls against ballast water and INNS risk.

    Rail Corridor Auditing

    Vegetation management contractor audits along rail corridors where knotweed spread risk is highest.

    Non-Conformance Reporting

    Clear, evidenced non-conformance reports with corrective actions and re-audit timescales.

    How the works run

    1. 1Scope agreementWe agree which sites, contractors and biosecurity protocols fall within the audit programme.
    2. 2Audit criteriaChecklists are built from your contract specification and the relevant legislation and codes.
    3. 3Site auditsUnannounced and scheduled visits assess actual practice against documented protocols.
    4. 4Findings reportNon-conformances are photographed, evidenced and rated by severity and repeat-risk.
    5. 5Re-auditCorrective actions are tracked and closed out with a follow-up visit within an agreed window.

    Why self-reported compliance isn't enough

    Most estate owners, port authorities, utility companies and rail infrastructure managers require biosecurity method statements from their contractors as a condition of works, but a method statement is only evidence of intent. We have repeatedly found wash-down stations installed but unused, boot-cleaning kit left in vans, and contaminated arisings loaded onto general haulage vehicles despite a signed protocol saying otherwise. An independent audit, carried out without warning where appropriate, tells you what is actually happening on the ground rather than what was promised in the tender.

    High-risk sectors we audit

    Ports and marine facilities carry particular biosecurity exposure through ballast water, hull fouling and imported aggregate or timber that can carry invasive non-native species, while rail corridors are recognised as one of the principal vectors for Japanese knotweed spread nationally because ballast and cutting maintenance regularly disturbs established stands. Utility companies face similar risk wherever excavation crosses land with known infestations. We tailor audit criteria to the specific pathways relevant to each sector rather than applying a single generic checklist.

    Biosecurity Auditing — common questions

    We audit any contractor working on your estate independently of who carried out the original treatment or biosecurity design.

    Yes, and for high-risk sites we recommend a mix of scheduled and unannounced visits to get a realistic picture of compliance.

    A written, photographed findings report rating each non-conformance, with corrective actions and a re-audit date.

    Yes, we set up scheduled multi-site audit programmes with a consolidated compliance dashboard for portfolio-level reporting.

    Yes, we tailor criteria to sector-specific risks such as ballast water and hull fouling at ports, and ballast and cutting disturbance on rail corridors.

    Questions above cover biosecurity auditing. For how we identify species, price surveys, keep treatments safe and what the 10-year guarantee covers, read our approach to weed control or the full frequently asked questions.
