Glenholme is a specialist healthcare provider supporting adults with learning disabilities, autism, and complex needs across 22 services nationwide. With over 700 staff and more than two decades of growth, we are a values-led organisation in an active phase of expansion — filling capacity, opening new services, and developing new sites. Growing the right services, in the right places, for the people who need them is central to our mission.

Glenholme is backed by STAR Capital (since Jun-26), with a strong focus on growth, operational improvement and value creation.

We are looking for an experienced, hands‑on Accounts Payable and Accounts Receivable Manager to join our finance team on a 3–9 month fixed‑term contract.
