Fractional vs Full-Time Head of Marketing: How to Decide

A fractional head of marketing gives you senior marketing leadership for an agreed number of days a week or month. A full-time head of marketing is a permanent employee, in the business every day. The right choice depends less on budget than on how much leadership work your business has, and how quickly you need it done.

I'm a Chartered Marketer based in Bolton, and I offer fractional B2B marketing. I have an obvious interest here, so I've set out where full-time is the better answer as well. You will also see this role called a fractional marketing director or fractional CMO. The titles overlap; what matters is whether the person owns strategy and pipeline or just one channel.

The benefits of going fractional

What you get from a fractional head of marketing

• Senior judgement without a full-time salary. Someone who has done the job before decides your positioning, priorities and plan, and you pay for the days you need.
• A fast start. No recruitment process, no search fee, no waiting for someone to work out their notice. Work can begin without waiting for a hiring process.
• A plan your team can run. The output is a clear strategy, priorities and measures that your people or suppliers can carry out, and that stay with you afterwards.
• Marketing and sales on the same page. An agreed definition of a qualified lead, who owns it, and how handover works.
• Fewer wasted pounds. Someone senior sets the brief and holds agencies and freelancers to it, so spend follows strategy rather than the other way round.
• Flexibility. The arrangement is agreed up front, with no employment obligations, and the scope can be reviewed as the business changes.
• An outside view. Fresh eyes on what is and isn't working, without internal politics.

What's the real difference?

A full-time head of marketing is embedded. They manage the team day to day, sit in every leadership meeting, and build institutional knowledge over time. A fractional head of marketing is brought in for the decisions that matter most: positioning, strategy, priorities, the plan, and who delivers it.

• Time. Fractional usually means one to three days a week, according to Practicus's UK guide. Full-time means five.
• Commitment. A fractional arrangement can be reviewed or ended on notice. A permanent hire brings notice periods, employment rights and recruitment costs.
• Starting point. Someone who has done the job elsewhere spends less of the first month learning the role.
• Presence. A full-time hire is there when something goes wrong at 4pm on a Friday. A fractional one is there on the agreed days.

When full-time is the better choice

• You are building an in-house team that needs managing daily.
• The volume of activity means someone has to be on top of it every day.
• You have a long-term mandate and the budget for a permanent salary.
• A rebrand, turnaround or crisis needs someone's complete attention.

If that is you, hire full-time. Fractional is not a cheaper version of the same thing. It suits different circumstances.

When fractional is the better choice

• You have capable people or agencies but no unifying strategy.
• Marketing is generating activity but not pipeline, and nobody senior owns the gap.
• The founder or managing director is still running marketing on top of their own job.
• You are entering a new market, repositioning or preparing for investment.
• You need senior judgement, but not five days a week of it.

This is common in complex B2B, where the work is mostly decisions about who to target, what to say to a buying committee, and how marketing and sales agree what counts as a qualified lead. Those decisions are senior and fairly infrequent. The execution around them can sit with a smaller team.

How the cost compares

The arithmetic has its own page: what a fractional head of marketing costs in the UK. In short, at about one day a week fractional usually costs noticeably less than a permanent hire. At two days a week it comes out close to a head of marketing's salary and employer costs. The difference is what you get for the money: senior judgement on the days you need it, no recruitment, and no five-day commitment.

Questions to ask yourself

1. If I hired the best head of marketing available tomorrow, would they have five days of work that only they could do?
2. Is my problem that nobody is doing the work, or that nobody senior is deciding what the work should be?
3. Do I have people who can carry out a strategy if someone else sets it?
4. How long do I need this leadership for? Six months to set direction is a different brief from five years of ownership.
5. What is left behind if the person goes? A good fractional arrangement leaves a plan and documents your team can run.

If your honest answers point to a strategy gap rather than a capacity gap, fractional is usually worth looking at first.

Common questions

Can a fractional head of marketing become full-time later?

Yes. Some businesses use fractional leadership to set the strategy and then hire a permanent head of marketing into a plan that already exists, which makes the role easier to define and the hire easier to judge.

Do they manage staff?

They can direct and coach a team or agencies, but they are no replacement for daily line management. That is one of the clearest signs you may need full-time.

Is fractional only for small businesses?

No. Larger B2B businesses also use it for specific projects such as repositioning or entering a new market.
