An effective marketing strategy is essential for any business that wants to succeed. A CMO can play a vital role in ensuring that a company’s marketing efforts are successful. With their expertise and leadership, hiring an interim CMO or a full time CMO can help to make sure that a company’s marketing strategy is on track and achieving its goals.
But hiring a full-time CMO can be costly and risky. Or maybe you need the expertise and experience of a CMO, but don’t have the requirements for a full-time one. That’s where hiring an interim CMO comes in.
In this article, we’ll cover what an interim CMO does, and why you might need one for your business.
The commercial pressure driving UK interim CMO demand has intensified in 2026. Average UK CMO tenure fell below 32 months for the first time on record (Marketing Week 2026 Career and Salary Survey), and UK marketing spend as a share of revenue reached its lowest level since 2020 in Q1 2026 (IPA Bellwether Report). For founder-CEOs and boards, this means the risk of a bad permanent CMO hire has never been higher — and the case for an interim engagement, followed by permanent hire only once the strategy is proven, has rarely been clearer.
What is an interim CMO?
As the name suggests, an interim CMO is a marketing executive who is brought in on a temporary basis to fill a leadership gap. Typically, hiring an interim CMO will be looked at when a company is undergoing a period of transition, such as a merger or acquisition. In these situations, an experienced marketing leader can be invaluable in helping to smooth the transition and keep the business on track.
Hiring an interim CMO can also be helpful in situations where a company is looking to make a major change to its marketing strategy. In this case, an interim CMO can provide fresh perspectives and ideas, while also having the experience and expertise to implement the new strategy effectively. Ultimately, an interim CMO can be a valuable asset for any business that find itself in need of temporary marketing leadership.
An interim CMO may come on full-time for a limited period, or as a fractional or part-time CMO depending on your business’ needs.
When should I look at hiring an Interim CMO?
The answer to this question depends on a variety of factors, including the size of your company, the industry you’re in, and your current marketing goals. However, there are a few general situations when hiring an interim CMO makes sense:
- You’re experiencing rapid growth and your marketing team is struggling to keep up. Hiring an interim CMO can help provide the expertise and marketing leadership needed to get things back on track.
- You’re looking to make a major shift in your marketing strategy. Hiring an interim CMO can be a great way to test out new ideas without making a long-term commitment.
- Your CMO has recently moved on or retired. An interim CMO can help fill the void until you’re ready to make a permanent hire.
- You need senior expertise and oversight for a specific project or campaign.
Ultimately, the decision of whether or not you should be hiring an interim CMO should be based on your specific needs and situation. However, in general, an interim CMO can be a great way to add expertise and flexibility to your marketing team.
What does hiring an interim CMO bring to a Marketing team?
A CMO brings a wealth of experience and knowledge to a marketing team. They have a deep understanding of the ever-changing landscape of marketing, and will be in charge of planning, developing and overseeing the marketing strategy.
Just as important will be the CMOs focus on the team to ensure they’re motivated, communicating regularly, and working together effectively and efficiently. They provide leadership and guidance, and they work to ensure that everyone is working towards the same goal.
As a high-level business leader, hiring an interim CMO with the right experience will help align the company’s marketing strategy with the business’ long-term objectives to ensure more revenue, greater profits, and faster growth.
How much does a CMO get paid?
The average salary for a CMO in the UK is £98,000 per year. However, salaries can vary widely depending on factors such as experience, education, and location.
An interim or fractional CMO will cost much less than this since they are working either part-time or on a contractual basis for a set number of hours each week. This is one of the major benefits of bringing on an interim CMO – you get all the experience and expertise of a senior business leader, at a fraction of the cost!
Head of Marketing and a CMO: what’s the difference?
The difference between a head of marketing and CMO is a bit like the difference between apples and oranges. Both are fruit, but they have different tastes and textures! In the same way, both a head of marketing and a CMO have different roles in an organisation.
A head of marketing is responsible for developing and executing marketing strategies. They work closely with other departments, such as product development and sales, to ensure that the company’s products and services are accurately represented to the public.
A CMO, on the other hand, is responsible for the overall marketing strategy of the company. They develop long-term plans and oversee all aspects of marketing, from advertising and promotions to market research and product development.
In short, a CMO is responsible for ensuring that the company’s marketing efforts are aligned with its overall business goals.
What skills should a CMO have?
A top CMO should be able to do the following:
- Create and deliver marketing strategies that align with your business goals.
- Ensure your marketing activity is using the right channels to find the right audience and maximising ROI.
- Identify profitable opportunities through new marketing channels or products.
- Identify your audience and make sure you are talking to them in the right way.
- Help companies develop their brand identities.
- Provide strategic support on product or software development.
- Manage, develop and mentor marketing team members.
- Deliver leadership, innovation and accountability to help drive business transformation.
What’s the difference between an interim CMO and a fractional CMO?
There a few subtle differences between a fractional and an interim CMO. But overall they perform the same role and have the same skillset and will be able to deliver an immediate impact to any business.
Interim CMO: a full-time or part-time CMO that is hired for a limited period of time, usually to fill a gap until a full-time CMO is found. Or they may be brought on to see if a full-time CMO would be a good fit for the company if they have not yet decided.
Fractional CMO: these typically fill a part-time role for companies who do not require a full-time CMO but need the expertise and leadership of a senior business leader in their marketing team. They usually work for several companies in the same capacity.
Frequently asked questions
How much does an interim CMO cost in the UK in 2026?
UK 2026 interim CMO day rates typically range £900–£1,600 per day depending on seniority and sector complexity. Full-time interim engagements (5 days per week) work out at £18,000–£32,000 per month. Part-time interim (2–3 days per week) at £7,500–£18,000 per month. This compares to a full-time CMO permanent hire at £175,000–£280,000 total compensation — which sounds cheaper on paper but excludes recruitment fees (typically 25–35% of first-year salary), notice periods, and the risk of a bad hire, which is meaningfully higher in senior marketing roles than in most other functions.
Interim CMO vs fractional CMO — which do I need?
Interim CMOs typically work full-time (5 days per week) for a defined period — 3–9 months is common — to fill a specific gap or lead a defined marketing agenda. Fractional CMOs typically work part-time (1–4 days per week) on an ongoing basis, embedded in the leadership team. If you have a specific short-term marketing need (rebrand, category launch, gap coverage after a departure), interim is usually right. If you want ongoing senior marketing leadership without the full-time cost, fractional is usually right.
How quickly can an interim CMO start?
The typical UK 2026 timeline is 2–4 weeks from initial enquiry to first working day. Chemistry sessions with 1–2 shortlisted candidates can be arranged within a week; contract terms agreed in week 2; first working day in week 3 or 4 depending on candidate availability. This is dramatically faster than the 3–6 months typically required to recruit and onboard a permanent CMO.
What deliverables should I expect in the first 90 days?
By day 30: full audit of marketing function, spend, team, agencies, current commercial performance. By day 60: prioritised list of 3–5 initiatives to focus on and clear rationale for what NOT to focus on. By day 90: initiatives visibly in motion, team engagement measurably up, and monthly reporting cadence established that shows commercial (not vanity) marketing metrics. Concrete outputs a good interim CMO will produce: refreshed positioning statement, updated messaging framework, agency and freelancer review, marketing team development plan, board-quality monthly report template.
When is an interim CMO the wrong choice?
Three situations where interim is not the right fit: (1) your business is smaller than £5 million turnover and marketing is still primarily founder-led — a fractional CMO or senior consultant is better value, (2) you have a specific product-marketing or channel-marketing gap rather than a strategic marketing leadership gap — hire a specialist, (3) you plan to promote an internal candidate within 6 months — mentoring or coaching for that candidate is a better spend than expensive interim leadership.
How is Leadership Services different from an interim CMO recruiter?
Traditional recruitment agencies match interim candidates to briefs and charge a recruitment fee (typically 20–25% of the interim's fees for the engagement duration). Leadership Services works differently: we're the direct engaging entity, we know our operator network personally, and we don't take recruitment fees on top of the day rate. Our pricing is published openly, which most interim providers still resist. If chemistry doesn't work, we introduce a different candidate at no additional cost — something recruitment agency models can't easily do.

So, if you’re looking for leadership but don’t want to commit to a full-time CMO position, or if your current CMO is on leave and you need coverage, we can help. Hiring an interim CMO from Leadership Services offer the perfect solution; they can work either as fractional or interim basis and give your business the guidance it needs without taking up all of your time.
