Legionella Risk Assessment & Testing

Water systems in empty or little-used buildings need a suitable plan before they are brought back into regular use. SafeSite Facilities can help arrange a Legionella risk assessment and the water hygiene work it identifies for vacant properties. Landlords and duty holders are legally required to assess and control Legionella risk, following HSE’s Approved Code of Practice (L8).

Match the work to the building and its water system

Stagnant water and reduced water use can increase hygiene risks. An assessment considers the system, how it has been managed during vacancy and the intended date of reoccupation. Sampling is arranged when the assessment or control plan calls for it; routine laboratory testing is not required for every domestic property.

Depending on the findings, the agreed scope may include:

• Reviewing water system information and the period of low use.
• Assessing accessible outlets, storage and system conditions.
• Recommending suitable flushing, monitoring or remedial measures.
• Flushing little-used outlets weekly during vacancy, which can be combined with our vacant property inspections.
• Arranging water sampling and laboratory analysis where appropriate.
• Providing a record of findings and recommended next steps.

A laboratory result is one part of water hygiene management and does not replace an appropriate risk assessment or ongoing controls. Risk assessments should be carried out by a competent assessor in line with BS 8580-1.

Prepare for reoccupation

Combine water hygiene work with utility reinstatement and other property checks when preparing a building for staff, visitors or a new tenant.
