{ “@context”: “http://schema.org”, “@type”: “JobPosting”, “title”: “Interim FP&A Modelling Consultant”, “description”: “

Central London | 3 days a week in office, 2 from home

6 months initially

Day Rate – Outside IR35 – £500-£600 depending on experience

ASAP start, interviews next week, 2 week notice maximum

Working with a PE-backed, asset-heavy infrastructure platform undergoing a period of investment, integration and operational build-out across Europe. Following a recent team change, they are looking to bring in an interim to take ownership of a critical modelling and planning remit.

This is not a pure “build from scratch” modelling role. The focus is on owning, maintaining and evolving a suite of live business models, while helping bring structure and consistency across a multi-entity, multi-system environment.

The Role

You will sit within the FP&A function, working closely with senior finance leadership, and take ownership of a portfolio of business-critical models across the group.

Key areas include:

  • Owning and maintaining multiple site-level business models across a growing portfolio of assets
  • Supporting and updating the group 5-year business plan, including consolidation of operational inputs, corporate costs and financing assumptions
  • Leading on capex modelling, tracking and challenge, working closely with delivery and operational teams
  • Supporting cashflow forecasting, funding visibility and returns analysis across a pipeline of projects
  • Working across teams (FP&A, sales, delivery, capital markets) to validate assumptions and improve model integrity
  • Bringing greater structure, consistency and governance to existing models and planning processes
  • Supporting ongoing integration work across geographies (notably UK and Germany) and multiple ERP systems

What They’re Looking For

  • Strong, hands‑on Excel modeller who is comfortable owning and working within complex, live models
  • Experience in capex-heavy, asset-led environments (infrastructure, telecoms, data centres, energy or similar)
  • Proven ability to work across multiple models, entities and imperfect data sets
  • Good understanding of how operational drivers translate into cashflow, funding requirements and returns
  • Experience supporting business planning, investment evaluation and forecasting in a commercial environment
  • Able to engage stakeholders, challenge inputs and operate visibly within the business

Additional Context

  • Multi-entity, international environment with ongoing integration across finance teams and systems
  • Existing models are in place, but require refinement, alignment and ongoing ownership rather than wholesale rebuild
  • Significant focus on capex planning, funding visibility and investment discipline
  • London-based role with regular in-office presence (3 days/week) to support collaboration
