Financial Controller

About Mentalwell
Mentalwell is a fast-growing telepsychiatry provider specialising in ADHD and autism.
We deliver care across England through the NHS, alongside services for private patients. Our focus is on making high-quality mental healthcare more accessible, efficient and patient-centred.
The Role
You will take ownership of the day-to-day finance function — including the ledger, month-end close, cash, receivables and financial controls — reporting directly to the CEO and CFO.
This is intentionally a broad, hands-on role. Initially, there will be no finance team beneath you: you will be responsible for completing the bank reconciliations as well as defining how they should be done.
In return, you will have genuine ownership of the finance function, direct access to senior leadership and the board, and the opportunity to build the team and processes around you as the business grows.
What You Will Own
Month-end close and a high-quality management accounts pack that gives the board a clear view of business performance
Accounts receivable and credit control across multiple clients
Accounts payable, clinician and freelancer payment runs, and supplier relationships
Payroll, working with our accountants on PAYE and pension obligations
Xero, including ledger integrity, the chart of accounts and accurate revenue recognition
Cash-flow forecasting and management of the working-capital cycle
HMRC filings and statutory compliance, working alongside our accountants
Audit and due-diligence readiness
Improving financial processes, controls and reporting as the business scales
About YouEssential
Qualified accountant — ACA, ACCA or CIMA
Strong, current Xero experience — this is essential
You have owned a month-end close end-to-end and produced management accounts that senior leaders have used to make decisions
Practical credit-control experience, with the confidence and persistence to manage it effectively
Comfortable being hands-on: you will be running reconciliations and managing the detail yourself, particularly at the outset
Able to explain financial information clearly to non-finance colleagues
Organised, commercially minded and comfortable operating in a fast-moving environment
Strongly Preferred
Experience in healthcare, NHS finance or another regulated environment
Experience supporting a transaction, fundraising process or financial due diligence
Experience in a fast-growing SME where processes were still developing and you helped build them
You do not need a large-company background or experience managing a substantial finance team. This is a role for someone who enjoys building a function, improving how things work and remaining close to the numbers.
What We Offer
Competitive salary, dependent on experience and location
Remote-first working — the role is primarily Xero-based and does not require you to be at a London desk. Hybrid working is available if preferred
A direct reporting line to senior leadership and involvement in the conversations that shape the business
Genuine scope to design the finance function and hire into the team as we grow
Pension, generous annual leave and paid study support
The opportunity to join a fast-growing healthcare business working to improve access to mental health services
