Wholesale Service Desk GSS Specialist (Performance Data Analyst)

Summary: We are looking for a high-caliber GSS Compliance & Data Analyst to join our team. This is a high-visibility role that sits at the intersection of regulatory compliance, advanced data analytics, and operational strategy. As our subject matter expert for the Guaranteed Standards Scheme (GSS), you won’t just be monitoring performance; you will be the architect of the data that informs our senior leadership. You will bridge the gap between complex datasets and executive decision-making, ensuring we meet our obligations to Ofwat while driving continuous service improvement. This role offers a unique platform to demonstrate both technical mastery and strategic leadership.

• 
  
• Advanced Data Analytics & Systems: Act as a "Power User" across our core systems. You will collate, clean, and analyse complex datasets from Maximo, our CRM, and billing platforms to provide a single, accurate version of GSS performance.
  
• Google Sheets Expert: Develop and maintain sophisticated reporting tools and automated dashboards. You must be highly proficient in advanced formulas (e.g., INDEX/MATCH, QUERY, ARRAYFORMULA) to model trends and forecast GSS expenditure.
  
• Stakeholder Influence & Presentation: Regularly present insights and performance trends to Directors and Senior Stakeholders. You must be able to translate technical data into compelling narratives that influence operational change and preventative actions.
  
• Regulatory Compliance & Audit: Ensure 100% accuracy in identifying and processing GSS claims for household and non-household customers. Lead regular audits to ensure adherence to Ofwat/Defra regulations and internal policies.
  
• Operational Improvement: Collaborate with Network Operations, Billing, and Field Services to investigate the root causes of service failures (GSS triggers) and proactively recommend process enhancements.
  

• 
  
• Technical Rigor: A degree (or equivalent experience) in Business, Data Analytics, Economics, or a related field.
  
• Systems Experience: Proven experience navigating asset management systems (ie Maximo) and customer management platforms.
  
• Spreadsheet Mastery: Expert-level Google Sheets skills are essential. You should be comfortable building complex models from scratch.
  
• Communication Presence: The ability to present data confidently at a Director level, with the interpersonal skills to influence stakeholders across the business.
  
• Industry Knowledge: Experience in UK Utilities (Water, Energy, or Telecoms) with a strong understanding of Ofwat’s GSS regulations and wider regulatory frameworks (e.g., PR24/PR29).
  
• Attention to Detail: An uncompromising approach to accuracy and a proactive attitude toward problem-solving.
