Job description
Senior Account Manager – Large Business Energy Sales
Location: UK (Hybrid / Flexible)
Job Type: Full-time, Permanent
About the Opportunity
My client is a leading UK energy organisation playing a critical role in helping British businesses and the public sector achieve Net Zero. Operating across multiple markets — including wholesale, residential, business energy solutions, and field services — the business is recognised for its scale, resilience, and ability to deliver value in a highly competitive and fast-evolving market.
With a multi-billion-pound turnover and a large UK-based workforce supported by international delivery teams, my client combines the stability of a major energy provider with the pace and commercial challenge of a modern energy business. The culture is built around ownership, openness, and continuous improvement, with a strong focus on delivering excellent customer and employee experiences.
The Team
The Large Business Sales function is responsible for managing and growing a portfolio of high-value electricity supply customers, typically organisations consuming 20GWh+ per year. The team focuses on flexible and structured supply contracts, long-term customer value, and the development of value-adding energy solutions and services.
The Role
As a Senior Account Manager, you will take ownership of a portfolio of complex, high-value electricity supply customers. You will be responsible for retaining and growing existing accounts while identifying and developing new commercial opportunities.
This is a senior, consultative role requiring strong commercial judgement, deep industry understanding, and the ability to build trusted relationships at multiple levels — including senior leadership and board-level stakeholders.
You will act as a subject matter expert across energy contracts, market dynamics, and regulation, working closely with internal pricing, risk, operations, and product teams to deliver commercially viable and customer-focused solutions.
Key Responsibilities
- Proactively develop and grow a portfolio of large, complex energy customers
- Achieve revenue and value targets through structured electricity supply contracts and value-adding products
- Use insight-led, consultative selling to link customer needs to energy solutions
- Identify and develop new business opportunities within existing and new accounts
- Build and maintain detailed account plans based on customer intelligence
- Lead multi-stakeholder engagement internally and externally to drive deal success
- Act as a senior ambassador for the organisation in customer and industry interactions
- Stay up to date with B2B energy markets, regulation, and commercial trends
- Ensure full compliance with governance, policy, and risk frameworks
What We’re Looking For
- Proven experience managing complex, high-value B2B customer portfolios
- Strong background in the energy sector, ideally within a deal-focused or wholesale environment
- Solid understanding of electricity markets, structured contracts, and risk management
- Ability to articulate complex commercial and financial scenarios clearly
- Confident engaging senior stakeholders and influencing decision-making
- Proactive, self-directed, and commercially driven
- Comfortable taking ownership and accountability for outcomes
- Collaborative mindset with the ability to work across multiple internal teams
Why Apply?
- Join a market-leading energy organisation central to the UK’s Net Zero transition
- Take ownership of a high-profile, high-value customer portfolio
- Operate in a commercially sophisticated and strategically important role
- Work within a culture that values ownership, transparency, and continuous improvement
- Long-term career development opportunities within a large, established energy group
