About your role

The Forecasting Manager is a central figure in enhancing visibility over debt volumes and projected bad debt charges. This role leads the creation and ongoing refinement of forecast models, ensuring that financial planning is accurate and responsive to changing business conditions. By tracking the performance of key bad debt initiatives—currently totalling £112 million—and identifying where delivery diverges from expectations, the Forecasting Manager supports the business in remaining agile and accountable.

The role has emerged in response to heightened internal and regulatory scrutiny around Business Debt Collection (BDC). With data now fragmented across two billing systems following recent migrations, there is a clear need for a dedicated forecasting specialist to rebuild robust processes and improve model accuracy. Historically, this work has been shared between Finance and the wider Credit team, but this standalone position will ensure greater consistency and insight going forward.

Beyond forecasting duties, this role contributes to provisioning and month-end processes, acting as a reliable source of backup and technical support to mitigate operational risks. As external attention from regulatory bodies such as Ofgem intensifies, the Forecasting Manager will serve as the designated contact point for BDC-related RFIs and formal data requests, helping to ensure timely and appropriate responses aligned with Centrica’s standards.

Key Accountabilities

The Forecasting Manager will be responsible for building and maintaining core forecasting models, including regular GFF and reforecasting processes that reflect actual performance against plan. They will deliver reporting that highlights variances, tracks initiative delivery, and supports strategic financial oversight.

Additionally, the role involves developing stakeholder relationships across Finance, Legal & Regulatory teams, and Senior Management within the Debt function, participating in discussions, presenting key findings, and representing the team in regulatory engagements.

Here’s what we’re looking for

• Highly numerate with strong analytical and financial acumen
• Demonstrable experience in forecasting and financial planning
• Sound understanding of accounting principles; CIMA or AAT qualifications (full or part) are desirable
• Proficient in Microsoft Excel, with expertise in formulas, models, and reporting tools
• Experience using Power BI to develop and present data-driven insights
• Capable of presenting complex data in clear and compelling formats for varied audiences
• Familiarity with UKH Credit & Collections processes and data
• Strong understanding of Centrica’s strategic goals and the wider commercial environment
• Proven ability to lead technical analysis and solve problems using logical and structured approaches
• Excellent communication and influencing skills, able to tailor messaging for both technical and non-technical stakeholders
