Managing Director vs CEO: Titles, Duties and What Actually Changes in a UK Business
UK company law recognises neither title, so the choice between managing director and CEO is a matter of convention rather than legal status, and what matters legally is whether the person is appointed as a director at Companies House. By convention a managing director runs the business day to day, while a chief executive sets direction and answers to the board, and in a growing firm the useful question is not which label to use but which decisions each person owns.
The legal position: titles carry no statutory weight
The Companies Act 2006 talks about directors, and it places the same general duties on every one of them, including the duty to promote the success of the company, to exercise independent judgement and to act with reasonable care, skill and diligence, regardless of whether their business card says managing director, CEO or nothing at all. Neither title is defined in the Act, which means that a CEO who is not on the board is, legally, an employee with a grand job title, whereas a managing director who is registered as a director carries the full set of statutory duties and the personal exposure that comes with them.
There is one wrinkle worth knowing, which is that the word director in a title can create expectations with third parties, so a person called managing director who has never been appointed to the board may be treated by clients or suppliers as having authority to bind the company. Many companies sidestep this by appointing whoever holds the top operational title as a statutory director, and if you are unsure whether your company needs a proper board at all, the distinctions in advisory board vs board of directors are a sensible place to start.
Rule of thumb: the title tells people how senior someone is, but only the board appointment and a written list of decision rights tell them what that person is allowed to decide.
Managing director vs CEO: the conventional difference in scope
In smaller UK businesses the two titles are often used interchangeably, and a founder who calls themselves managing director of a 30-person firm is usually doing exactly what a CEO does elsewhere. The distinction becomes meaningful when both titles exist in the same company, or when a group structure puts a CEO above several operating companies, each of which has its own managing director.
What a CEO conventionally owns
The chief executive owns direction, which in practice means the strategy and the choices about which markets, services and clients to pursue, the relationship with the board and investors, capital allocation, the senior hiring that shapes the leadership team, and the external profile of the business. The CEO is accountable to the board for the overall performance of the company, and it is the CEO who takes the call when an investor wants to understand why the quarter was lumpy.
What a managing director conventionally owns
Where the two roles coexist, the managing director usually owns the running of the business, which covers delivery, resourcing, utilisation, margin, operational processes and the people who make all of that happen. That brings the role close to a chief operating officer, and the difference is often one of emphasis rather than substance, since a managing director tends to carry profit and loss accountability for the operation while a COO is more often framed as the engine room behind a CEO.
Why founders search for this, and the real question underneath
The search usually happens at a specific moment, when a founder of a technology services business somewhere between 20 and 60 people has decided to bring in someone to run the day to day and must now decide what to call that person and what to call themselves. The titles feel like the decision, but they are the easy part, because the difficult part is that the founder has been making every decision for years and the new hire cannot run anything until some of those decisions genuinely move.
A common pattern is that the founder keeps the CEO title, hires a managing director, and then continues to approve every hire, every discount and every resourcing change, so that the new managing director becomes a well-paid messenger and leaves within eighteen months. This is founder-as-routing-layer with a more expensive org chart, and no choice of title will fix it, because the problem is that nobody wrote down what moved.
A title is a promise about authority, and a promise that is not honoured in the first difficult week is worse than no promise at all.
How to write down what each role decides
The practical work is to produce a short decision-rights document that both people sign up to, which sits alongside the job descriptions and is far more useful than either of them. The approach in our decision rights playbook works well here, but the core of it can be done in an afternoon.
- List the recurring decisions. Write down the decisions that come up every month, such as pricing a proposal, approving a hire, moving a person between projects, escalating a troubled account, signing a contract above a certain value and changing a delivery process.
- Assign a single owner to each. Every decision gets one name, not two, because shared ownership in practice means the founder decides and the other person waits.
- Set thresholds where needed. Many decisions split cleanly by size, so the managing director may approve hires within an agreed budget and discounts up to an agreed level, with anything beyond that going to the CEO.
- Name who is consulted and who is informed. The CEO can still be told about every senior hire without being the person who approves it, which is a distinction that preserves visibility without recreating the bottleneck.
- Agree a review date. Revisit the document after three months, when you will know which thresholds were set too tight and which decisions are quietly drifting back to the founder.
Keeping a CEO and managing director from treading on each other
Overlap is inevitable at the boundary between direction and operations, because a strategic decision to enter a new market has delivery consequences and an operational decision to turn down a difficult client has strategic ones. The answer is not to pretend the boundary is clean but to agree how disputes are settled, which usually means a short weekly meeting between the two, a clear rule that the CEO does not countermand the managing director in front of the team, and an understanding that disagreements go to the board only when they cannot be resolved between the two people.
Worked example: a client asks for a ten per cent discount on a renewal. If the agreed threshold for the managing director is fifteen per cent, the managing director decides and tells the CEO afterwards, and if the founder then reopens the decision, the document has failed and needs either amending or honouring.
It also helps to be honest about what the founder enjoys, because a founder who loves solving delivery problems will drift back into them unless the decision document makes that drift visible, whereas a founder who has always preferred selling and strategy will usually let go with relief once the boundary is written down.
Choosing titles for your own top team
If you are a founder hiring an operational leader, the most common and least confusing arrangement is for you to be CEO and for the new hire to be managing director or COO, with the choice between those two depending on whether you want them to carry full profit and loss accountability for the operation. If you intend to step back further, perhaps towards a chair role, then naming the new hire CEO from the outset avoids a second title change later, which investors and acquirers tend to read as instability. Whichever you choose, appoint the person as a statutory director if they will genuinely run the company, and make sure your governance reflects who actually decides.
Where Vitori fits
Many founders can do this work themselves, and the decision-rights exercise above needs no outside help if both people are candid with each other. Where it tends to stall is in the months after the document is written, when old habits pull decisions back towards the founder and the new leader lacks the standing to push back. Vitori works with founder-led technology services businesses at exactly that point, using the Operational Scale Framework to diagnose where decisions currently sit and, through the Operator model, embedding to make the new structure hold, whether that ends with a permanent managing director in place or a founder who has simply learned to stay out of the way. It is not the right answer for every leadership change, but where the goal is a business that runs, and scales, without the founder in every decision, you are welcome to start a focused conversation with us.
