Job description
Government Property Profession Career Framework (Link)
This role sits within the following:
Job Family – Strategic Asset Management
Core Role – Property Data Management
Level – Practitioner
An exciting national opportunity exists for a Deputy Legionella & Water Hygiene Subject Matter Expert (SME) to support robust, proportionate Legionella risk management across a complex UK-wide estate. The role is central to Business As Usual (BAU) Legionella governance, providing the technical oversight, assurance and reporting required to protect people, assets and organisational reputation.
Operating under the technical direction and governance of the National Water Hygiene SME, the post holder leads BAU technical activity, ensuring Legionella risks are identified early, controlled effectively and escalated appropriately. The role maintains national visibility of the risk position, emerging issues and systemic weaknesses, translating operational and CAFM data into clear, evidence-based risk narratives to inform governance-level decisions.
The Deputy SME provides assurance that Legionella control regimes remain effective across diverse building types and system configurations, including oversight of Water Risk Assessments, written schemes of control and control-measure delivery, ensuring continuous alignment with ACOP L8 and HSG274.
Independent of commercial and contractual management, the role delivers proportionate engineering challenge, ensuring remedial works and system modifications are technically sound, risk-led and represent best value for money. Through structured BAU reporting, weekly operational engagement and clear escalation, the post holder supports effective governance, sustained risk reduction and continual improvement in Legionella control at a national scale.
What we are looking for
If you’re someone who can use your technical expertise to strengthen Legionella risk control and provide clear, evidence-based assurance at a national level, we want to hear from you. Most importantly, we are looking for individuals who are motivated by delivering effective, proportionate and sustainable water safety management that protects people, assets and organisational reputation.
Drawing upon your mechanical engineering knowledge and Legionella risk management experience, you will play a key role in supporting the National Water Hygiene SME by leading Business As Usual (BAU) technical activity. You will provide day-to-day oversight of Legionella control arrangements, ensuring risks are identified early, control failures are understood, and corrective actions are progressed through the appropriate governance and operational routes.
Working across a complex, multi-site estate, you will engage routinely with operational stakeholders, providing clear technical direction, assurance and challenge to support compliant outcomes. You will review and quality assure Water Risk Assessments (WRAs), written schemes of control and CAFM-based compliance evidence, ensuring that Legionella control measures are technically correct, practical and aligned with ACOP L8 and HSG274.
The role requires strong analytical and communication skills, translating operational performance data into clear national risk narratives, reports and governance packs. Through structured BAU reporting, weekly operational engagement and targeted escalation, you will support informed decision-making, prioritisation of risk and continual improvement in Legionella control.
This role is not a contract or commercial management position; instead, it provides independent technical assurance and risk-based recommendations that enable delivery teams to act with confidence. Your work will have a direct and tangible impact on national water safety assurance, helping to maintain safe environments and demonstrate robust statutory compliance.
Duties and Responsibilities

Collate, review and present Legionella risk and performance information to support governance forums, operational meetings and technical oversight, translating operational data into clear risk-based narratives.
In conjunction with key stakeholders, review and quality assure Legionella Water Risk Assessments (WRAs), written schemes of control and associated action plans, ensuring they are technically accurate, practical and reflective of system configuration.
Work closely with operational teams and assurance functions to support the definition, tracking and closure of corrective actions, ensuring actions are prioritised based on risk and supported by appropriate evidence.
Support the definition, implementation and monitoring of key performance indicators and assurance metrics relating to Legionella control, using CAFM data and other compliance information as the evidence base.
Use the CAFM system on a daily basis to review work order evidence, interrogate PPM compliance, identify exceptions and track corrective actions to closure.
Provide technical challenge and assurance on proposed remedial works, system modifications and engineering solutions, ensuring they are proportionate to risk, technically correct and represent best value for money.
Support investigations into control failures, adverse trends or suspected Legionella-related incidents, contributing to root cause analysis and the definition of effective corrective actions.
Play an active role in weekly operational water safety and Legionella meetings, providing the BAU technical position, escalating key risks and supporting clear ownership and timescales for action.
