CMO vs Head of Marketing: Which Does Your UK Business Actually Need?
Last updated: 26 May 2026
The short answer: a Head of Marketing leads the marketing team and runs the marketing plan; a Chief Marketing Officer leads the marketing function at board level and is accountable for marketing as a commercial discipline. They are not the same job, they cost very different amounts, and the wrong choice can set a UK business back twelve to eighteen months. This guide explains what each role actually does, what each costs in 2026, and how UK leadership teams should decide which one is right for the business they have today.
The headline difference: scope and seniority
A Head of Marketing is a senior operational marketing leader. They own the marketing plan, lead the marketing team day-to-day, manage agency relationships, deliver campaigns, and report into a Marketing Director, CMO or Managing Director.
A CMO (Chief Marketing Officer) is a board-level executive. They own the marketing strategy, sit on the leadership team, contribute to the commercial direction of the business, lead the marketing organisation rather than just the marketing team, and are accountable to the CEO and the board for marketing as a strategic discipline.
The distinction is not about job-title inflation. It is about where decisions are made. A Head of Marketing executes well against an agreed strategy. A CMO sets the strategy in the first place — and is the marketing voice in board-level conversations about pricing, product, customers and commercial trade-offs. Robert Half’s 2026 UK marketing salary data puts the median CMO total compensation in London at £200,000, against a Head of Marketing range of £90,000–£120,000 nationally.
CMO vs Head of Marketing: what each role actually does
A clear view of the day-to-day responsibilities helps UK leadership teams pick the right role.
What a CMO does
- Owns the marketing strategy and is accountable to the board for it
- Sits on the senior leadership team and contributes to commercial decisions beyond marketing
- Sets the marketing budget and defends it at board level
- Builds and shapes the marketing organisation (not just the marketing team)
- Owns marketing’s contribution to revenue, customer acquisition cost, lifetime value and brand value
- Acts as the senior external voice of marketing — with investors, partners, analysts and major customers
- Hires, develops and challenges the Head of Marketing, Marketing Director, and senior agency partners
What a Head of Marketing does
- Owns the marketing plan and is accountable for delivering it
- Leads the marketing team day-to-day — coaching, performance, hiring at junior to mid level
- Runs the campaign calendar, content programme, channel mix and reporting cycle
- Manages agency relationships against agreed briefs and budgets
- Reports into a Marketing Director, CMO or Managing Director — usually weekly
- Translates strategy into measurable execution and feeds insight back upwards
- Owns specific marketing functions in smaller businesses (for example, demand generation or brand)
Cost: CMO vs Head of Marketing in the UK in 2026
The salary gap is significant. The figures below combine Robert Half’s 2026 UK salary data, Intelligent People’s 2026 marketing salary survey and the wider UK 2026 employer market.
- Head of Marketing UK 2026 salary: £90,000–£125,000 base, with most national roles between £90,000–£105,000 and London roles £105,000–£125,000.
- CMO UK 2026 salary: £125,000–£250,000 base, with the median at £187,500 and the 75th percentile in London at £250,000.
Add 25–35 percent for employer National Insurance, pension contributions, benefits and recruitment costs, and the fully loaded annual cost lands as follows:
- Head of Marketing UK fully loaded 2026: £115,000–£170,000 per year.
- CMO UK fully loaded 2026: £160,000–£340,000 per year.
The fully loaded cost difference between the two roles is typically £80,000–£200,000 a year. That is a meaningful capital allocation decision for a UK SME, and it should be made deliberately — not by hiring up because a competitor did.

Which role does your business need? Five signals
Five signals usually decide which role a UK business needs at a given stage.
Signal 1: Where marketing fits at board level
If marketing is a line item in the board pack that the MD presents, you need a Head of Marketing. If marketing is a board-level strategic discussion that needs a senior voice in the room every month, you need a CMO.
Signal 2: Size of the marketing function
A Head of Marketing typically leads a team of 3–10 marketers. A CMO typically leads a function of 10+ marketers across multiple disciplines (demand generation, brand, content, product marketing, lifecycle, analytics). If your marketing team will not exceed 6–8 people in the next two years, a Head of Marketing is almost certainly the right answer.
Signal 3: Revenue stage
UK SMEs under £10m revenue rarely need a permanent CMO. A Head of Marketing or a fractional CMO is usually a better fit. Businesses in the £10m–£50m revenue band sit in the genuine grey area and should pick based on the other signals here. Above £50m revenue, the CMO role usually justifies itself.
Signal 4: Commercial complexity
Multiple products, multiple territories, multiple buyer types and a complex pricing model — these all increase the case for a CMO. A single product, a single home market and a simple pricing model usually means a Head of Marketing is enough.
Signal 5: Investor and exit context
Businesses preparing for funding, sale or partnership are often expected to have a CMO. Investors and acquirers look for a senior marketing voice that can speak to commercial outcomes, growth assumptions and customer economics. If you are 12–24 months from an exit event, the CMO conversation gets harder to defer.
The fractional CMO option: avoiding a forced choice
Many UK businesses sit in the grey area where a Head of Marketing is not quite enough but a permanent £200,000 CMO is not yet justified. A fractional CMO solves precisely this problem: a senior, board-grade marketing leader working with your business one to three days a week at a meaningfully lower cost. According to the CIPD’s flexible working research, senior part-time roles are now one of the fastest-growing UK executive employment patterns.
A common UK pattern in 2026 is a Head of Marketing leading the team day-to-day, with a fractional CMO sitting above them — providing strategic challenge, board reporting and senior coaching. This combination typically costs £150,000–£190,000 a year fully loaded versus £250,000–£340,000 for a permanent CMO plus a Head of Marketing — a £60,000–£190,000 annual saving while keeping both seniority and execution capacity.
How to make the decision
A structured way to make the CMO vs Head of Marketing decision for your UK business:
- List the five signals above and assess your business against each. Be honest. Do not hire up just because a competitor or a recruiter suggests you should.
- Map the business strategy for the next 24 months. What does marketing actually need to deliver? Is that a plan-and-execute job or a strategy-and-board-leadership job?
- Test the cost case. Take the fully loaded annual cost of the role you think you need and stress test it against marketing’s expected revenue contribution.
- Consider the fractional CMO alternative. Especially for businesses in the £5m–£25m revenue band, the Head of Marketing plus fractional CMO model often outperforms either single hire.
- Decide on a 24-month horizon, not a 6-month one. Senior marketing hires take 18–24 months to compound. Choose the role you will still want in two years.
Frequently asked questions about CMO vs Head of Marketing
Q: What is the main difference between a CMO and a Head of Marketing?
A: A Chief Marketing Officer is a board-level executive who owns the marketing strategy and contributes to commercial decisions across the business. A Head of Marketing is a senior operational leader who owns the marketing plan and leads the marketing team day-to-day. In short, the CMO sets the strategy; the Head of Marketing delivers against it. The CMO sits on the leadership team; the Head of Marketing typically reports into a Marketing Director, CMO or Managing Director.
Q: How much does a CMO cost in the UK compared to a Head of Marketing in 2026?
A: In 2026, a UK Head of Marketing earns £90,000–£125,000 base salary (£115,000–£170,000 fully loaded). A UK CMO earns £125,000–£250,000 base salary (£160,000–£340,000 fully loaded). The fully loaded cost difference is typically £80,000–£200,000 per year, depending on location and seniority.
Q: When should a UK SME hire a CMO instead of a Head of Marketing?
A: A UK SME should usually consider a CMO when marketing is a recurring board-level strategic discussion, the marketing team will exceed 8–10 people in the next two years, the business is approaching or past £25m revenue, there is genuine commercial complexity across products, territories or buyer types, or the business is 12–24 months from a funding round or exit event. Below those thresholds, a Head of Marketing is usually the right answer.
Q: Can a Head of Marketing be promoted to CMO?
A: Sometimes, yes — but not automatically. The two roles require different skill sets. A Head of Marketing tends to be strong on plan execution, team leadership and channel delivery. A CMO needs board-level commercial fluency, the ability to lead a function rather than a team, and the gravitas to be the marketing voice in pricing, product and strategy conversations. Many Heads of Marketing make the transition successfully with coaching and exposure to board-level work, often through a fractional CMO mentor.
Q: What is the alternative to choosing between a CMO and a Head of Marketing?
A: For UK SMEs in the £5m–£25m revenue band, the most common alternative is a Head of Marketing supported by a fractional CMO. The Head of Marketing leads the team and delivers the plan, while the fractional CMO provides strategic direction, board reporting and senior coaching one to three days a week. This combination typically costs £150,000–£190,000 a year fully loaded — a £60,000–£190,000 annual saving compared with a permanent CMO and Head of Marketing pairing.
