About the Role

We are a fast-growing UK manufacturer of stainless-steel hot water cylinders and engineered hot water storage solutions. We design and manufacture unvented hot water cylinders, calorifiers, buffer vessels, volumisers, thermal stores, and high-volume pre-plumbed assemblies for leading heat pump manufacturers and heating-sector customers. As an ISO 9001-certified manufacturer, we are committed to delivering consistent quality, reliable supply, technical excellence, and outstanding customer support. Due to continued growth and significant new OEM programmes, we are seeking an experienced Key Account Manager to manage a portfolio of our most strategic OEM customer relationships.

The focus is on the commercial and operational management of major accounts, supporting customers from product development and launch through to ongoing production, growth, and supply. You will act as the primary link between customers and our teams across Engineering, Production, Purchasing, Quality, Logistics, Aftersales, and Commercial functions. Success in this role requires the ability to build strong senior-level relationships while managing the detail behind forecasts, product changes, production planning, delivery performance, contracts, pricing, and customer satisfaction.

- Knowledge of ISO 9001 quality systems and change-control processes.

- Project management or commercial qualification.
