Fractional Finance Director Services across South East England
Senior CFO and Finance Director support for owner-managed businesses across Berkshire, Surrey, Buckinghamshire, Oxfordshire, Hampshire and Hertfordshire. Regional reach, practical local engagement, and genuine board-level judgment.
Regional reach across the South East's most important business belts
The South East of England is one of the most commercially diverse regions in Europe. The M4 technology corridor through Berkshire and into the Thames Valley, Surrey's affluent professional services and family business base, Oxfordshire's research and spin-out economy, Hampshire's defence, marine and engineering clusters, and Buckinghamshire's manufacturing, media and logistics hubs sit within a short drive of each other. Hertfordshire and Greater London extend that picture north and east.
We support owner-managed businesses and scale-ups across all of these sub-regions from our Maidenhead base. The common thread is senior finance leadership: management information that actually informs decisions, forecasting and cash discipline that stands up to scrutiny, and transaction readiness for businesses considering a trade sale, private equity process, management buyout or Employee Ownership Trust. For businesses that want a more focused local view, we also maintain dedicated county and town pages which you can explore below.

Which counties across the South East do you cover?
We work with businesses across Berkshire, Surrey, Buckinghamshire, Oxfordshire, Hampshire, and the adjacent parts of Hertfordshire and Greater London. Our Maidenhead base sits at the intersection of the M4, M40 and M25, so the entire region is within practical reach.
Is there a specific local page for my county or town?
Yes. We maintain focused pages for Berkshire, Surrey, Reading, Maidenhead, London and the City of London, each with county and town-specific context. This regional page links out to them and covers the broader South East picture.
How do you work with businesses spread across the South East?
Most engagements combine regular on-site board meetings with remote delivery between sessions. For clients along the M4, M3, M40 and M25 we typically meet monthly or bi-weekly, supported by video calls and shared reporting tools in between.
What sectors do you specialise in across the South East?
We work across Thames Valley technology and SaaS, Surrey professional services and family businesses, Oxfordshire research and spin-out businesses, Hampshire defence and engineering suppliers, and Buckinghamshire manufacturing and media. The connecting theme is owner-managed businesses with £3m to £50m turnover.
What makes a fractional FD suitable for South East businesses?
South East businesses often need sophisticated finance leadership but cannot yet justify a full-time FD on a Thames Valley or M25-belt salary. A fractional arrangement delivers senior experience at a fraction of the cost, scaled up or down as the business moves through growth, investment, or exit.
Can you support South East businesses through a transaction?
Yes. Trade sale, private equity, management buyout and Employee Ownership Trust transactions are a core part of what we do. We improve financial information quality, forecasting and diligence readiness well before the formal process begins.
