Fractional C-Suite vs Full-Time Hire: The Real Cost Comparison
A fractional C-suite director costs between £1,500 and £6,000 per month, while a full-time executive hire costs £130,000 to £260,000 or more per year once salary, employer National Insurance, pension, benefits, and recruitment fees are included. For UK SMEs that need senior leadership but cannot justify a full-time executive salary, the fractional C-suite model delivers the same calibre of expertise at 50 to 70 per cent less cost. This guide breaks down the real numbers so you can make an informed decision.
The true cost of a full-time C-suite hire in the UK
The headline salary for a C-suite director is only the starting point. Since April 2025, the cost of employing senior executives has increased significantly thanks to changes in employer National Insurance contributions.
According to GOV.UK rates and thresholds for 2025-26, the employer NIC rate rose from 13.8% to 15%, while the secondary threshold dropped from £9,100 to £5,000. On a £150,000 executive salary, that means £21,750 per year in employer NIC alone.
Here is what a typical full-time C-suite hire actually costs:
- Base salary: £100,000 to £180,000 depending on the role and sector
- Employer National Insurance (15%): £14,250 to £26,250 per year
- Pension contributions (5%): £5,000 to £9,000 per year
- Benefits package: £5,000 to £15,000 per year (private medical, car allowance, life insurance)
- Recruitment fees (20-25% of salary): £20,000 to £45,000 as a one-off cost
- Annual leave cost: 28 days statutory minimum, equivalent to approximately 11% of salary
Once you add these together, a full-time C-suite director with a base salary of £150,000 costs the business approximately £200,000 to £240,000 per year in total — before you account for the recruitment fee or the three to six months it typically takes to find the right person.
What does a fractional C-suite director cost?
A fractional C-suite director is an experienced executive who works with your business on a part-time basis, typically one to three days per week. Because they are engaged as an independent professional rather than an employee, there is no employer NIC, no pension obligation, no benefits package, and no recruitment fee.
Typical fractional C-suite UK costs by role:
- Fractional CFO: £2,000 to £6,000 per month
- Fractional CTO: £2,500 to £6,000 per month
- Fractional CMO: £2,000 to £5,000 per month
- Fractional COO: £2,000 to £5,000 per month
- Fractional HR Director: £2,000 to £6,000 per month
At a typical engagement of two days per week, a fractional C-suite director costs £24,000 to £72,000 per year. Compare that to the £200,000+ total cost of a full-time equivalent and the saving becomes clear.
Fractional C-suite vs full-time: a side-by-side comparison
The cost difference is significant, but it is not the only factor. Here is how the two models compare across the dimensions that matter most:
Annual cost. Full-time: £200,000 to £260,000 total employer cost. Fractional: £24,000 to £72,000 per year. Saving: 50 to 70 per cent.
Time to start. Full-time: three to six months for recruitment, notice periods, and onboarding. Fractional: typically within one to two weeks. For businesses that need leadership quickly, this alone can be decisive.
Commitment. Full-time: permanent employment contract with redundancy obligations if the role is no longer needed. Fractional: flexible engagement with no long-term tie-in, typically with a 30-day notice period.
Experience breadth. Full-time: deep experience within one or two organisations at a time. Fractional: works across multiple businesses simultaneously, bringing cross-sector insight and proven frameworks that accelerate results.
Availability. Full-time: five days per week, available for day-to-day management. Fractional: one to three days per week, focused on strategy, governance, and high-value activities. Not suited to roles requiring daily operational management of large teams.
Risk. Full-time: significant financial commitment; if the hire does not work out, you face notice periods, potential settlement agreements, and a fresh recruitment process. Fractional: lower financial risk with the ability to adjust or end the engagement quickly.
When a full-time hire makes more sense
The fractional model is not right for every situation. A full-time C-suite hire is the better choice when:
- Your business is large enough to generate five days per week of genuine C-suite work in a single function
- The role requires daily operational management of a large team — for example, a CTO managing 30 or more developers
- You are preparing for an IPO, major acquisition, or transaction that demands full-time executive attention over 12 months or more
- The role is deeply embedded in regulatory compliance where continuous presence is required
For businesses with revenue above £20 million and established management structures, a full-time hire often makes sense because the volume and complexity of work justifies the investment.
When a fractional C-suite director is the smarter choice
For the majority of UK SMEs — the 5.7 million businesses that make up 99.9% of the UK’s private sector — a fractional C-suite director is often the more practical and cost-effective option. The fractional model works best when:
- You need strategic leadership but cannot justify £200,000 or more per year for a single hire
- Your business is growing and you need senior expertise now, not in three to six months
- You want to test whether a particular C-suite function adds value before committing to a permanent appointment
- You need expertise across multiple functions — a fractional CFO and a fractional CTO combined may still cost less than one full-time director
- You are navigating a specific challenge — fundraising, digital transformation, restructuring — that requires senior input for a defined period
The hidden costs most businesses forget
When comparing fractional C-suite UK costs against full-time hires, several hidden costs tip the balance further in favour of the fractional model:
Failed recruitment. Executive search firms typically charge 20 to 25 per cent of first-year salary. If the hire does not work out — and industry data suggests that 40 per cent of senior hires leave or are removed within 18 months — you face the same fee again.
Opportunity cost. A three-to-six-month recruitment process means three to six months without senior leadership in that function. For a growing business, that delay can cost far more than the salary saving.
Underutilisation. Many SMEs hire a full-time director and find that only 40 to 60 per cent of their time is spent on genuinely strategic work. The rest is filled with operational tasks that a more junior team member could handle. With a fractional director, you pay only for the strategic days you need.
Frequently asked questions
Q: Can you have more than one fractional C-suite director?
A: Yes, and this is increasingly common. Many SMEs engage a fractional CFO and a fractional CTO, or a fractional CMO and a fractional HR director, at the same time. Two fractional directors working two days each per week typically cost less than a single full-time hire, while giving the business access to senior expertise across two functions instead of one.
Q: Is a fractional director an employee or a contractor?
A: A fractional director is typically engaged as an independent professional through their own limited company. This means employer National Insurance, pension obligations, and statutory benefits do not apply. The engagement is governed by a service agreement rather than an employment contract, which provides flexibility for both parties.
Q: How do fractional directors integrate with the existing team?
A: A good fractional director integrates as if they were a permanent member of the leadership team. They attend board meetings, build relationships with direct reports, and take accountability for outcomes in their function. The part-time nature of the engagement does not diminish their authority or commitment — it simply means they focus their time on the highest-value activities.
Q: What happens if my business outgrows the fractional model?
A: This is a sign of success. When a business reaches the point where it needs a full-time director, the fractional director can help recruit and onboard their permanent replacement, ensuring a smooth transition. Some fractional directors also offer the option to convert to a full-time role if both parties agree it is the right fit.
