What Does a CFO Do? Role and Responsibilities
- 8 min read
A CFO, or chief financial officer, is the senior executive responsible for a company's financial strategy. The role decides where capital is invested, how the business is funded, how financial risk is controlled, and how performance is reported to the board, investors and lenders. In most UK companies it is the most senior finance appointment, and the person who answers for the numbers when they matter most.
The simplest way to understand the job is to see the CFO as the executive who turns financial information into decisions. A finance team can produce accurate accounts and forecasts, but someone has to decide what they mean for the next investment, the next funding round and the risks the business is willing to carry. That judgement, exercised in front of a board and defended to investors, is what the role exists to provide.
This guide explains what the job involves day to day, how the responsibilities fit together, and how the role changes with the type of company. If your interest is the route into the role and the credentials it takes, see our guide on how to become a CFO in the UK. Here the focus is the job itself.
The CFO's Core Responsibilities
A CFO's remit is wide, but it resolves into six responsibilities. Together they connect the numbers a company reports to the decisions it makes about growth, funding and risk, and each one carries its own trade-offs for the board to weigh.
Financial strategy and capital allocation
The CFO sets the financial plan behind the company's strategy and decides how limited capital is put to work. In practice this means ranking competing uses of cash, from organic investment and acquisitions to debt reduction and returns to shareholders, and testing each against expected return and risk. Measures such as net present value give a common basis for comparison, but the harder work is judgement about which forecasts are credible and which investments the business can fund without straining the balance sheet.
Funding and capital structure
A company can pursue the right strategy and still fail if it is financed badly. The CFO decides the mix of debt and equity, manages relationships with banks and investors, and keeps the weighted average cost of capital as low as the company's risk allows. This covers debt facilities, covenants and, in growth companies, the timing and size of each funding round. The trade-off is constant, because cheaper debt lifts returns but adds refinancing and covenant risk, while equity is more forgiving yet dilutes existing owners.
Reporting, controls and risk
Underneath every decision sits the requirement that the numbers are right. The CFO owns the integrity of financial reporting and the internal controls behind it, from statutory accounts to the management information the board sees each month. The same mandate covers financial risk, including liquidity, currency and credit exposure, and the assurance work that auditors and lenders depend on. When controls are weak, even sound strategy becomes hard to trust, which is why this stewardship remains the foundation of the role and not an administrative afterthought.
Board, investor and lender relationships
Much of a CFO's value lies in explaining performance and plans to the people who hold the company to account. That means writing board papers and reporting to the audit committee, working within the framework of the UK Corporate Governance Code for listed companies, and speaking directly to investors and lenders. The underlying skill is translation, turning detailed financial results into a clear account of what happened, what it means, and what the board is being asked to decide.
Transactions
Acquisitions, disposals and refinancings usually run through the CFO. The role leads the finance workstream, valuing a target with methods such as discounted cash flow, stress-testing the deal case, and overseeing due diligence and integration once a deal completes. Because a transaction concentrates risk and capital in a single decision, the CFO's judgement on price and structure often determines whether the deal creates value or destroys it.
Leading the finance function
Finally, the CFO builds and leads the finance team across accounting, financial planning and analysis, treasury and tax, and owns the systems and data that produce reliable numbers. As a company grows, this includes deciding what to automate and how to scale reporting without losing control, so that financial data becomes insight the rest of the business can act on. A strong finance function extends the CFO's reach, while a weak one absorbs all of their time.
What a CFO Does in a Typical Week
No two weeks are identical, but the rhythm is recognisable. A CFO usually starts from the numbers, reviewing the latest forecast and the cash position and working through the variances that matter with the finance team. Ahead of a board meeting, much of the week goes into the board pack, which is less about presenting results and more about framing the two or three decisions the board actually needs to take. Preparation for the audit committee follows a similar pattern, because the questions there tend to concern risk, controls and the reliability of what is being reported.
The rest of the week is outward-facing. A CFO might take a call with a lender about a facility, challenge the business case behind a proposed investment, or talk an investor through recent performance. Between these set pieces, the CFO spends time with the CEO and the wider leadership team on operational and commercial questions, because most business decisions become financial ones before long. The balance between inward stewardship and outward influence is what separates the role from the senior technical positions beneath it.
How the Role Changes by Company Type
The six responsibilities stay constant, but their weight changes with who owns the company and how mature it is. A listed-company CFO spends far more time on regulated reporting and the market's view of performance, while a founder-backed CFO may spend most of the week keeping the business funded. The table below sets out where attention tends to concentrate in four common settings, and how the job title often changes with them.
| Company type | What the CFO focuses on | Typical title |
|---|---|---|
| Listed company | Regulated reporting, investor relations, governance under the UK Corporate Governance Code, and the market's view of performance | CFO, often an executive director |
| Private equity-backed | The value creation plan, leverage and cash, tight reporting to the sponsor, and preparing the business for exit | CFO |
| Venture-backed scale-up | Fundraising and runway, unit economics, and building the finance function from an early base | CFO or VP Finance |
| SME or family business | Funding, controls and hands-on finance across the whole business, often with a small team | Finance director, often the same role |
In smaller companies the CFO and finance director titles frequently describe the same job, while in larger and investor-backed businesses they separate, with the finance director running the finance function and the CFO carrying wider strategic and board responsibility. We look at that boundary in our guide on finance manager vs CFO.
CFO Job Description (UK Template)
The responsibilities above translate into a fairly standard job description. The template below is a practical starting point for a UK CFO role, and you can adjust the detail to the size and sector of the company.
Role: Chief Financial Officer (CFO)
Reports to: Chief Executive Officer, with a direct line to the board and its audit committee
Purpose of the role: Lead the company's financial strategy, protect its financial health, and give the board and investors a clear, reliable view of performance and risk.
Key responsibilities:
- Set financial strategy and lead capital allocation across the business.
- Manage funding, capital structure and relationships with banks and investors.
- Own financial reporting, controls, tax and risk management.
- Report to the board and audit committee and support governance.
- Lead acquisitions, disposals and refinancings, including valuation and due diligence.
- Build and lead the finance team, systems and data.
Typical requirements:
- A professional accountancy qualification such as ACA, ACCA or CIMA is usual, though not mandatory.
- Senior finance experience, commonly including a financial controller or finance director role.
- A track record of board reporting and, in many cases, funding or transaction experience.
Key skills: capital allocation, valuation, funding, governance, risk management and leadership, with the judgement to connect all of them to strategy.
Who the CFO Works With
The CFO sits at the centre of a company's financial relationships, and managing them well is as much a part of the job as the analysis behind them. Internally, the closest partnership is with the CEO, whose strategy the CFO helps shape, cost and fund. Around that sit the leadership team, who rely on the CFO to connect their operational plans to budgets and returns, and the finance team itself, which the CFO leads and develops.
Externally and at board level, the CFO answers to the board and its audit committee, presents to the investors and lenders who provide the company's capital, and works with the external auditors who independently test the numbers. Each audience makes a different demand: the board wants clarity on risk and the decisions in front of it, investors want a credible account of returns, and auditors want evidence. Holding those audiences at the same time, without losing the confidence of any of them, is a defining feature of the role.
The Skills Behind the Role
Underneath the day-to-day work sit five disciplines that a board expects a CFO to command, from corporate finance and business valuation to corporate governance, private capital and mergers and acquisitions. Professional accountancy training builds the technical base in reporting and control, and these disciplines are what turn that base into board-level judgement, the ability to value an option, price a deal, read a governance obligation and understand how investors think. It is the combination, not any single skill, that separates a finance leader from a finance manager.
Build the finance behind the role
The CLFI CFO Programme develops four of these disciplines, namely corporate finance, business valuation, private equity and M&A. It is four courses across nine modules, about 14 hours of content, and most participants complete it in 3 weeks. It is delivered online and self-paced, with hybrid and in-person options, and carries CPD accreditation on the corporate finance course.

Frequently Asked Questions
What does a CFO do in a small company?
In a small company the CFO is hands-on and often carries the finance director title. The role covers funding, cash and controls, statutory reporting, and financial support to the owner or CEO, usually with a small team and less specialisation than in a large business. The judgement is the same, but the CFO does more of the work personally.
Is a CFO the same as a finance director?
Sometimes. In smaller UK companies the two titles often describe the same job. In larger and investor-backed businesses they differ, with the finance director running the finance function and the CFO taking a wider strategic and board-facing role. We explain the distinction in our comparison of the CFO, finance director and financial controller roles.
Does the CFO sit on the board?
It varies. In listed companies the CFO is often an executive director and a formal member of the board. In private companies the arrangement differs, and the CFO may attend board meetings and present without being a statutory director. Either way, reporting to the board is central to the role.
What qualifications does a CFO need?
Most UK CFOs hold a professional accountancy qualification such as ACA, ACCA or CIMA, combined with senior finance experience, though none is strictly mandatory. Our guide on CFO qualifications and the career path sets out the detail.
What is the difference between a CFO and a CEO?
The CEO leads the company as a whole and owns overall strategy and performance. The CFO leads financial strategy and is typically the CEO's closest partner on capital, funding and risk. The CFO advises and challenges on the numbers, while the CEO carries final accountability for the business.
