The Finance Manager takes full ownership of the day-to-day finance function for the Southeast (Southern) division, based at Ruskin House, Battle, and for the new Wessex division. The role drives financial health, statutory compliance and commercial insight.

The Southeast runs a high volume of jobs each month, each with its own costs, valuation and application cycle, so the role has real scope to shape how finance operates. Wessex is currently reported within London and is planned to become a stand‑alone division in 2027.
