Ready to make a real impact where it matters most? At Thames Water, we're not just keeping taps flowing and toilets flushing for 16 million customers - we're building a more resilient, sustainable future. As an Environmental Site Auditor, you'll be at the heart of that mission, leading site audits, supporting operational teams, and driving continuous improvement. If you've got a passion for the environment, strong stakeholder skills, and the drive to ensure we meet our commitments, this is your chance to help shape the future of water.

• Undertake site environmental and permit compliance audits as per the annual audit programme for your geographic region.
• Carry out audits on any permitted asset including Sewage Treatment Works, Pumping Stations, Water Treatment Works, Waste and Air emissions facilities.
• Provide support and training to operational teams so that they understand the requirements of the EMS.
• Support operational teams in preparation and during external audits.
• Create summary reports of your audits and present these back to Operational Managers.
• Highlight any non-compliances and drive actions to completion in your region using the EMS.
• Provide regular reports on the progress of the audit programme within your region and key areas of risk/concern.

• Annual Leave - 26 days holiday per year, increasing to 30 with the length of service. (plus bank holidays)
• Performance-related pay plan directly linked to company performance measures and targets.
• Generous Pension Scheme through AON.
• Access to lots of benefits to help you take care of you and your family's health and wellbeing, and your finances - from annual health MOTs and access to physiotherapy and counselling, to Cycle to Work schemes, shopping vouchers and life assurance.
