Northern Trains Limited (NTL) intends to procure a contract for the provision of Legionella Management Services across its estate. The proposed procurement seeks to appoint a single supplier to deliver a comprehensive Legionella management and water hygiene service across NTL´s stations, depots, train care centres, offices, sidings and operational facilities. The overarching objective is to ensure compliance with statutory obligations, Approved Code of Practice (ACOP) L8, HSG274 guidance and Northern´s internal health and safety requirements, whilst reducing operational, regulatory and reputational risks associated with Legionella bacteria and water hygiene management. The successful supplier will deliver a fully integrated service covering Legionella risk assessments, reviews of existing assessments, development and maintenance of Written Schemes of Control, water hygiene monitoring, routine sampling and testing, laboratory analysis, compliance auditing, technical consultancy, training and incident response support. The supplier will also be responsible for maintaining accurate compliance records and supporting Northern in the effective management of its water systems and associated assets. A key requirement of the contract will be the provision of a flexible and responsive service model capable of supporting a geographically dispersed estate comprising stations, depots and operational facilities with differing risk profiles and operational requirements. The supplier will be expected to respond to emerging compliance risks, positive sample results, regulatory changes, audit findings and ad-hoc operational requirements throughout the contract term. In addition to service delivery activities, the supplier will provide all associated contract management, supervision, reporting, technical expertise and support systems required to maintain compliance and provide assurance to Northern. The supplier will be expected to deliver and maintain an electronic compliance management system incorporating asset registers, risk assessments, schematics, sampling results, remedial actions, performance reporting and management information. The supplier will work collaboratively with Northern stakeholders to develop improvement plans, support audits and inspections, and ensure compliance activities remain aligned with business needs and evolving legislative requirements. Performance will be managed through a suite of key performance indicators covering service delivery, regulatory compliance, response times, reporting accuracy, audit performance, training delivery and management information. A strong emphasis will be placed on partnership working, continuous improvement, innovation, data-driven decision making and proactive risk management. The procurement aims to establish a strategic partnership that delivers a safe, compliant and effective Legionella management service, protecting employees, contractors, visitors and customers whilst supporting Northern´s wider health, safety and operational objectives.
