• Communicate any site issues, access problems or cancellations promptly to the Field Service Manager.


• Work safely at all times, including when working alone, travelling between sites and working at height where required.


• Maintain a high standard of service and professionalism when dealing with clients and site contacts.


• Support occasional ventilation surveys and indoor air quality monitoring following appropriate training.


• Undertake occasional overnight stays where required by the location of client sites.

Who you are

• Strong working knowledge of ACOP L8 and HSG274.


• Previous experience carrying out Legionella risk assessments, including producing written reports and schematic drawings.


• A good understanding of domestic water systems across a range of building types.


• Excellent attention to detail, with strong technical report writing skills.


• Confident communicating with clients, site teams and colleagues at all levels.


• Organised, self motivated and able to plan and manage a varied workload independently.


• Comfortable working alone and travelling regularly to client sites.


• Good IT skills, including experience using Microsoft Office.


• A full UK driving licence is essential.


• Experience in indoor air quality monitoring, closed water systems or water treatment would be beneficial, but is not essential.
