About the role

Behind every impactful retrofit initiative is a team that keeps things running smoothly. This role ensures that Energiesprong UK can deliver high-quality work: on time, on budget, and with the professional collaboration our partners rely on.

‍

As a Business Administrator, you’ll provide essential support across finance, operations, HR, procurement, and general administration. Your work will help our mission-led organisation stay efficient, organised, and able to focus on delivering meaningful change across the retrofit sector.

‍

This role offers flexible working arrangements, ideal for someone who is highly organised, detail-driven, and motivated by work that contributes to a more sustainable future. You’ll be joining a small but committed team working to transform how homes are retrofitted across the UK.

‍

Remote working is fully supported, though being based in the Midlands, Bristol, or London is helpful if you’d like occasional in-person time with colleagues.

Why this role matters

‍

• Smooth, reliable operations – ensuring payments, invoices, budgets, and timesheets are handled accurately and on time.
• Confident decision-making – providing clear reporting and up-to-date financial and resource information.
• Strong governance – supporting Directors and Board processes so the organisation remains accountable and well-run.
• Excellent partner experience – ensuring clients, suppliers, and collaborators receive timely and professional communication.
• Capacity to grow – maintaining strong internal systems that support the organisation’s ambition and mission.
