Position title
Fractional CFO / Part-Time Finance Director | High-Growth Clean Energy Storage Business | Cambridge
Description
FD Capital is working with a fast-scaling clean energy storage company to appoint a Fractional CFO / part-time Finance Director.
The business designs and supplies battery energy storage systems for residential and commercial customers, and its trajectory is exceptional: revenue has grown from £300k in 2024 to £3.5m in 2025, and is now scaling towards £7m in 2026.
Growth at that pace, in an inventory-heavy hardware business with significant purchasing from China, creates exactly the finance challenges you'd expect — working capital strain, FX exposure on gross margin, and the need for controls and reporting that keep up with the business. The founders now want senior, commercially minded finance leadership to bring structure and strategy to the next stage.
Responsibilities
The Role
Initially around one - two days per week for three months, with scope to adjust as the business needs, likely increasing in 12 month time
Own cashflow forecasting and working-capital management through a period of rapid scaling
Develop a sensible FX strategy — budgeting exchange rates, timing currency purchases, assessing hedging options, and protecting gross margin and cashflow from currency swings on Chinese supply
Advise on tax planning and capital investment — use of allowances and managing the company's tax position efficiently and compliantly
Drive gross margin analysis and cost control
Plan stock purchasing and inventory-related cash requirements
Build investor-ready financial modelling and board reporting
Strengthen management accounts and financial controls
Support fundraising, including SEIS/EIS-related considerations
Qualifications
About You
Qualified accountant (ACA / ACCA / CIMA) with FD or CFO experience in early-stage or high-growth companies
Background in hardware, energy, manufacturing, distribution or another inventory-heavy sector strongly preferred
Practical experience managing FX exposure on international supply chains — ideally China sourcing
Strong on UK tax planning, capital allowances and SEIS/EIS
Commercially minded and hands-on — comfortable building models and controls yourself, not just directing others
Experience supporting fundraising rounds an advantage
