PFAS in the UK: Why Regulatory Scrutiny Is Increasing in 2025

PFAS, or per- and polyfluoroalkyl substances, are increasingly under scrutiny in the UK as regulators respond to growing evidence of their persistence and potential environmental and health impacts. Often described as “forever chemicals”, PFAS do not readily degrade in soil or groundwater, meaning contamination can remain long after the original source activity has ceased.

In recent years, the Environment Agency and other UK bodies have made it clear that PFAS should be considered where there is a credible source–pathway–receptor linkage. While there is not yet a single consolidated PFAS regulation in the UK, the regulatory direction of travel is clear. Emerging contaminants are expected to be assessed proactively rather than addressed reactively once problems arise.

For developers, this shift has practical consequences. Sites with industrial histories, firefighting activities, waste management uses or manufacturing processes may now attract greater scrutiny at planning and regulatory stages. PFAS can influence remediation strategies, restrict soil reuse options and introduce long-term liability concerns if not identified early.

A proportionate PFAS assessment allows developers to understand whether PFAS are present and, if so, whether they pose a material constraint to development. Early assessment supports better design decisions, realistic cost planning and clearer dialogue with regulators.

EnviroSolution provides UK-focused PFAS assessment services aligned with current guidance and regulatory expectations. By addressing PFAS early in 2025, developers can reduce uncertainty, protect programmes and demonstrate responsible environmental management.
