About us

A water hygiene company built by engineers, for facilities teams.

AP Environmental Ltd is a Hertfordshire-based water hygiene and Legionella specialist led by directly qualified engineers with extensive experience across commercial, healthcare, education and residential portfolios. We deliver both the assessments and the mechanical remedial works that follow them — in-house, under one accountable team.

Our story

AP Environmental was built around a simple observation our engineers kept making in the field: too many building owners were stuck in the same loop — receive a Legionella risk assessment from one provider, then chase a separate sub-contractor to fix the findings. Remedial work would slip, accountability would blur, and water safety would drift.

We work to a different model. Our engineers are qualified to carry out both the assessment and the mechanical/plumbing works that flow from it — meaning a single accountable team from inspection through to fix and verification.

That structure also drives honest reporting. We have no incentive to over-specify remedials, because we're the ones doing them. We identify what's necessary, agree it with you, and deliver it.
