We are now looking for a

Senior Account Manager

to join our Metering - Support Services division. This is a key role within the business, responsible for managing and delivering on existing client contracts. Unlike traditional account management roles, this position is not sales-focused. Instead, it requires a hands-on, operationally minded individual who can take ownership of service delivery, lead a team, and ensure our clients receive the highest levels of support and performance.

About the Role

This is a role for someone who thrives on getting involved in the detail, solving problems, and making things happen. You will be the primary point of contact for a portfolio of key clients, ensuring that their needs are met through effective service delivery and operational excellence. You'll lead a team responsible for account management and billing/dispute resolution, and work closely with internal stakeholders to ensure that all contractual obligations are fulfilled efficiently and professionally.


You'll be expected to build strong, long-term relationships with clients, not by selling, but by delivering consistently high standards of service and by being a trusted operational partner. Your ability to lead, influence, and drive performance will be critical to the success of this role.

Key Responsibilities

Take full ownership of the operational delivery of existing client contracts, ensuring all services are delivered to agreed standards and timelines. Act as the main point of contact for key clients, building strong relationships based on trust, transparency, and performance. Lead and manage a team of Account Managers and Billing/Disputes professionals, providing guidance, support, and development opportunities. Oversee the resolution of billing issues and disputes, ensuring accuracy, timeliness, and client satisfaction. Collaborate with internal teams including operations, finance, and compliance to ensure seamless service delivery. Monitor and report on contract performance, identifying areas for improvement and implementing solutions. Support contract renewals, pricing discussions, and scope changes, ensuring alignment with client needs and business objectives. Maintain a deep understanding of client requirements, industry developments, and regulatory changes to ensure ongoing compliance and relevance. Champion a culture of continuous improvement, operational efficiency, and customer focus within your team and across the wider business.

What We're Looking For

Proven experience in account management and operational delivery, ideally within the utilities, infrastructure, or service delivery sectors. A hands-on, proactive approach with a strong focus on execution and results. Demonstrated ability to lead and develop high-performing teams. Excellent communication and interpersonal skills, with the ability to manage stakeholders at all levels. Strong analytical and problem-solving skills, with a keen eye for detail. Full UK driving licence and access to your own vehicle.

Desirable:

Experience in the metering or wider energy sector. Degree in Business, Operations Management, or a related field. Familiarity with industry regulations and compliance requirements.
