Fractional Finance Services

Fractional finance is part-time, subscription-based access to a senior finance professional such as a CFO, Finance Director, Treasurer or Group Financial Controller. The Lumen Collective provides fractional finance services to UK SMEs on monthly plans starting from £2,500, delivering hands-on support embedded in your business rather than advice from a distance. The firm is ICAEW-regulated and led by a triple-qualified founder (ACA, CTA, FCT).

Flexible, Senior Finance Leadership Without the Permanent Hire

Not every business needs a full-time CFO or Finance Director, but every ambitious business needs access to senior finance expertise. The Lumen Collective provides fractional finance professionals who work alongside your team on a subscription basis, giving you consistent, hands-on support that scales with your business.

Our fractional finance leaders operate as part-time members of your team, not as external advisers producing reports from a distance. Whether you need a Finance Director to run day-to-day operations, a CFO to lead board-level strategy, a Treasurer to manage cash and risk, or a Group Financial Controller to consolidate and control across multiple entities, we match the right level of seniority to your needs.

Who This Is For

Fractional finance is designed for UK SMEs and scaling businesses that need experienced finance leadership but are not ready for, or do not need, a permanent senior hire. Typical situations include businesses preparing for fundraising or acquisition, companies growing rapidly without adequate finance infrastructure, organisations navigating complex compliance or reporting requirements, and owner-managed businesses looking for a strategic finance partner.

How It Works

We deliver fractional finance through three subscription tiers, each designed around a stage of business maturity. Plans can be combined or tailored to your specific requirements. All engagements are led by qualified professionals (ACA, CTA, FCT) with experience across practice, industry and financial services.

Why The Lumen Collective

The Lumen Collective is an ICAEW-regulated firm of Chartered Accountants, led by a founder who is also a Chartered Tax Adviser and Fellow of the Association of Corporate Treasurers. This breadth of qualification means your fractional finance leader can handle accounting, tax and treasury matters directly, reducing the need for multiple external advisers and keeping your costs down.

Frequently Asked Questions

What is fractional finance?

Fractional finance means engaging a senior finance professional, such as a CFO, Finance Director, Treasurer or Financial Controller, on a part-time, subscription basis rather than hiring permanently. You get the same calibre of expertise at a fraction of the cost and commitment.

How many days per month are included?

This depends on the tier and your specific needs. Foundation typically covers a few days per month focused on core compliance and visibility. Performance and Transformation tiers involve more regular involvement, often including attendance at board or leadership meetings.

Can I change tier as my business grows?

Yes. Plans are designed to scale with you. Many clients start at Foundation and move to Performance or Transformation as their business evolves or enters a new phase.

What qualifications do your finance leaders hold?

Our founder holds ACA (Chartered Accountant), CTA (Chartered Tax Adviser) and FCT (Fellow of the Association of Corporate Treasurers) qualifications, with senior experience at PwC, Grant Thornton, Revolut and Corpay.

How is fractional finance different from using an accountancy firm?

Traditional accountancy firms typically work on compliance deliverables at arm's length. Fractional finance means we work inside your business, using your tools, attending your meetings and operating as an embedded member of your team.
