Interim Finance Lead | London | 4-Month Assignment

• London | Fully office-based
• Start: 7 September 2026
• Duration: Until 14 December 2026
• Interim | 5 days per week

I’m currently recruiting for an Interim Finance Lead to join a fast-paced, growing business on a critical 4-month assignment. This is a hands-on, high-impact role for someone who can step into a finance function, take ownership and deliver against tight deadlines.

The key objectives

The assignment has two major deliverables, both required by 14 December 2026:

1. 2027 Budget

• Lead the preparation of detailed 2027 budgets across the group.
• Ensure budgets are built on verified historical and current-year performance.
• Work with key stakeholders to achieve full buy-in and board approval.

2. Funding Due Diligence

• Build a lender-ready data room to support an upcoming funding raise.
• Ensure financial information is accurate, reconciled and fully supported.
• Develop the financial narrative around the business, growth and expansion plans.

What you'll be doing

Alongside the key deliverables, you will:

• Take ownership of weekly cash management and the 12-week rolling cash flow forecast
• Review and verify the balance sheet, resolving legacy issues
• Review prior and current-year P&L performance
• Strengthen finance processes, controls and reporting
• Assess the existing finance team, systems and processes
• Make recommendations around the longer-term finance structure
• Work alongside the existing Financial Controller and wider finance team
• Bring in additional interim resource where required to protect the December deadline

Candidate Profile:

• Hands-on and delivery-focused
• Strong in cash flow, budgeting and financial control
• NetSuite fluent (essesntial)
• Comfortable working in fast-paced, high-growth or entrepreneurial environments
• Experienced in challenged or transforming finance functions
• A strong communicator and confident stakeholder manager
• A builder and documenter, rather than someone who simply reviews existing processes
• Comfortable using AI tools such as Claude to work efficiently

Desirable: Finance transformation, audit, fundraising/due diligence experience, or experience running a small finance function.

This is a great opportunity for an experienced interim who enjoys getting stuck in, creating structure and delivering tangible results under pressure.
