Every growing business reaches the same uncomfortable moment. The founder is spending Sunday evenings writing warning letters. A grievance has been sitting unresolved for a month because nobody knows whose job it is. An office manager is doing their best with contracts downloaded from the internet. The conclusion everyone jumps to is the same: "we need to hire someone in HR."
Sometimes that is right. Often it is premature — and the more common mistake is not hiring HR too late, but hiring the wrong level of HR for the problem you actually have. There is a third option between doing it yourself and a full-time hire, and it deserves an honest evaluation before you write a job advert.
The real question: what problem are you buying a solution to?
Before comparing options, be precise about the gap. In our experience, the pain at this stage of growth is usually some mix of four things:
- Live employee relations issues — disciplinaries, grievances, absence and performance cases that need experienced handling now.
- Compliance foundations — contracts, policies, right-to-work and payroll hygiene that may never have been properly built.
- Manager capability — line managers promoted for technical skill who have never been taught to manage people.
- Administration — the volume of onboarding, leavers, holiday records, letters and payroll inputs.
Here is the crucial observation: the first three need senior judgement; the fourth needs administrative capacity. They are rarely found in one affordable person.
The hiring trap: paying junior money for a senior problem
The typical first HR hire for a 30–60 person business is an HR advisor or HR manager on a salary somewhere in the £35,000–£55,000 range (indicative market figures — benchmark your specific role before advertising). That is a significant fixed cost: with employer National Insurance, pension and overheads, budget roughly 1.25–1.35 times the salary as the true annual cost.
The trap is this. A hire at that level can absolutely run your administration and your recruitment logistics. What they usually cannot yet do — because it takes years of casework to learn — is calmly steer a complex grievance involving a senior employee, judge whether a dismissal is defensible, or redesign your organisation's structure. So the founder keeps carrying the hardest decisions anyway, now alongside a new salary. The reverse hire — a senior HR Director at £80,000–£120,000-plus — solves the judgement problem but leaves a £90,000 person filing holiday forms, and most 40-person businesses do not have forty hours a week of senior-level HR work to fill.
This is not a criticism of HR professionals; it is a mismatch between the shape of the problem and the shape of a single hire.
What fractional HR actually is
Fractional (or retained, or outsourced senior) HR means buying a slice of a senior practitioner's time — typically a set number of days or hours per month — rather than a whole person. Done properly, it is not a helpline and not a template library. The practitioner learns your business, your managers and your history, and gives advice shaped by that context.
The honest comparison:
Fractional HR buys you:
- senior judgement on live issues from day one, without a three-month recruitment cycle;
- experience across many businesses and many cases — pattern recognition a first-time internal hire cannot have;
- flexibility to scale support up during a restructure and down in quiet periods;
- cost that tracks the actual volume of senior-level work, which in most SMEs is a few days a month, not five days a week;
- no employer NI, pension, holiday, sick pay, desk, laptop or notice period.
A full-time hire buys you:
- physical presence and constant availability;
- someone who lives your culture daily and builds deep internal relationships;
- administrative capacity in the same package (at junior level);
- a long-term investment in internal capability that compounds.
The decision framework
Ask four questions, honestly:
1. What is the ratio of judgement work to administration? If your pain is mostly live ER cases, risk and structure, that is judgement — buy seniority. If it is mostly onboarding volume, holiday tracking and recruitment logistics, that is administration — hire junior capacity (an HR administrator or people operations coordinator) and consider senior support only for the exceptions.
2. How many days a month of senior-level work do you actually have? List the senior tasks from the last quarter and estimate hours. Most 20–80 person businesses land at two to six days a month. If that is your number, a full-time senior hire will be underused or will fill the gap with work that does not need their salary.
3. What does a mistake cost versus the options? A mishandled dismissal or discrimination claim costs tens of thousands in settlement or awards plus months of management time. The relevant comparison is not "fractional fee versus salary" — it is "fractional fee versus salary, versus the cost of the mistake the junior hire was not equipped to prevent."
4. What is the endgame? Fractional support and hiring are not enemies. The pattern that works well: fractional senior support now, handling judgement work and building your foundations properly; junior administrative hire when volume justifies it; and a first senior internal hire — at the right level — when the business genuinely has forty hours a week of senior work, often somewhere well past 100 employees. A good fractional partner will tell you when you have reached that point, because keeping a client who has outgrown the model serves nobody.
When fractional is the wrong answer
Honesty cuts both ways. Fractional support is the wrong choice when you need someone on-site daily (multi-site frontline workforces with constant casework often do), when your volumes are already large and stable, or when you want HR deeply embedded in leadership culture as a permanent seat at the table. And any external arrangement fails if it is treated as a fire-and-forget helpline — the value comes from continuity and context, whoever provides it.
Decision checklist
- The actual pain mapped: judgement vs administration
- Senior-level hours per month honestly estimated
- True cost of a hire calculated (salary × ~1.3 plus recruitment time)
- Risk cost of a mishandled ER case weighed against both options
- Level of hire matched to level of problem (junior hire ≠ senior capability)
- Flexibility needs considered (restructure season vs steady state)
- Endgame defined: what triggers a move to an internal senior hire
- Any external support structured for continuity, not ad-hoc calls
The practical takeaway
The choice is not between "no HR" and "an HR hire". It is between three shapes of support — and the businesses that choose well are the ones that start by defining the problem rather than writing the job advert. For most growing businesses, senior judgement a few days a month, wrapped around capable internal administration, is the shape that fits the stage they are actually in.
