Written Schemes of Control

A written scheme of control outlines the procedures required to manage and control the risk of Legionella bacteria in water systems. It forms a key part of Legionella compliance under HSE ACOP L8 and HSG274 guidance, helping duty holders implement effective monitoring, maintenance and record keeping procedures.

What is a Written Scheme of Control?

A written scheme of control is a documented management plan that outlines how an organisation will control and manage Legionella risks within its water systems.

Following a Legionella risk assessment, duty holders must implement appropriate control measures to ensure water systems remain safe. The written scheme of control details these procedures, defining how monitoring, maintenance, and inspections should be carried out.

This document provides a clear framework for managing water hygiene risks and demonstrating compliance with UK health and safety legislation.

Why is a Written Scheme of Control Important?

Under HSE ACOP L8, organisations responsible for buildings with water systems must ensure that appropriate control measures are in place to manage Legionella risks.

A written scheme of control helps organisations:

  • Clearly define Legionella control measures

  • Establish monitoring and inspection procedures

  • Assign responsibilities to responsible persons

  • Maintain accurate compliance records

  • Demonstrate compliance with HSE guidance

Without a structured control scheme, organisations may struggle to demonstrate that Legionella risks are being effectively managed.

What Does a Written Scheme of Control Include?

A written scheme of control typically outlines the procedures required to manage water safety across a building or estate.

This may include:

  • Overview of the water systems present

  • Identification of control measures

  • Monitoring procedures and frequency

  • Temperature monitoring requirements

  • Inspection and maintenance procedures

  • Responsibilities of the responsible person

  • Record keeping requirements

  • Corrective actions if issues are identified

The scheme provides a clear framework for managing water hygiene risks on an ongoing basis.

Who Needs a Written Scheme of Control?

Many organisations are required to maintain a written scheme of control where Legionella risks exist within their water systems.

This commonly includes:

  • Commercial offices

  • Schools and universities

  • Healthcare facilities

  • Hotels and hospitality venues

  • Industrial sites and factories

  • Gyms and leisure facilities

  • Care homes and supported living environments

  • Property management companies and landlords

Any organisation responsible for water systems should ensure that appropriate Legionella management procedures are documented.
