-   Review and challenge the preparation of statutory accounts to ensure technical accuracy and consistency across the Group.
-   Provide technical accounting guidance on FRS 102 and other complex accounting matters.
-   Lead, mentor and coordinate the Financial Control team through year-end and audit.
-   Partner closely with the Group Finance Director and wider leadership team on finance transformation and M&A activity.

-   Extensive hands-on experience of group consolidations involving 50+ entities.
