Many organisations assume that appointing a competent water hygiene contractor transfers responsibility for Legionella management and ACOP L8 compliance. Unfortunately, this is a common misunderstanding.

Under ACOP L8, responsibility for managing the risks associated with water systems remains with the duty holder and those appointed to manage water safety on their behalf. Whilst contractors play an important role in monitoring, inspection, sampling and remedial works, they do not own the risk.

This distinction becomes particularly important when organisations operate complex estates, multiple buildings or ageing water systems.

Common Governance Gaps

During independent reviews, common issues often include:

  • Written Schemes of Control that do not reflect actual site arrangements.
  • Contractor reports being filed but not reviewed.
  • Remedial actions remaining open for extended periods.
  • Unclear allocation of Responsible Person duties.
  • Limited management oversight of contractor performance.
  • Water Safety Groups that meet infrequently or not at all.

In many cases, contractors are carrying out the tasks they have been instructed to undertake, but nobody is independently checking whether the overall management system remains effective.

Governance Versus Contracting

Water hygiene contractors are generally responsible for delivering agreed services.

Water safety governance focuses on whether those services are appropriate, effective and aligned with ACOP L8 requirements.

This includes:

  • Reviewing Written Schemes of Control.
  • Assessing contractor performance.
  • Verifying completion of remedial actions.
  • Supporting Responsible Persons.
  • Providing independent compliance assurance.
  • Reporting risks and gaps to senior management.

Demonstrating Defensible Compliance

Regulators, insurers and investigators will often look beyond contractor reports and ask:

  • How was performance monitored?
  • How were findings reviewed?
  • Who was responsible for ensuring actions were completed?
  • How was compliance assured?

Being able to answer these questions is a key part of demonstrating defensible compliance.

Independent Water Safety Governance Support

At Shield Water, we provide independent water safety governance support for estates, education, heritage, leisure and other complex organisations.

Our focus is not on undertaking monitoring or remedial works, but on helping duty holders understand, manage and demonstrate effective control of their water safety arrangements.

Water safety is not just about completing tasks. It is about ensuring the management system behind those tasks is effective, proportionate and defensible.
