Why “we’ll hire someone junior for now” is the most expensive Marketing decision

There’s a moment almost every ambitious business hits. Growth has been decent, the founder or MD has been carrying marketing on top of everything else, and the conversation turns to: right, we need someone to own this properly.

And then, almost without exception, the same instinct kicks in. Not now. Not at that level. Let’s get a junior or mid-level marketer in first, get some momentum, and revisit senior leadership once budget allows. It feels sensible. It feels careful, even. In an economic climate where every cost is being scrutinised, hiring “smaller” looks like the responsible choice. I think it’s usually the opposite. And the numbers back that up.

The cost of hiring has changed, quietly

Since April 2025, the cost of putting anyone on payroll in the UK has gone up in ways that don’t show up on the job spec. Employer National Insurance rose from 13.8% to 15%, and the threshold at which it kicks in dropped from £9,100 to £5,000 (https://www.sage.com/en-gb/blog/employers-national-insurance-rise/). Employment Hero’s research with YouGov puts the overall rise in the cost of employing someone in the UK at close to 10% once you account for this alongside wage increases (https://employmenthero.com/uk/blog/employer-national-insurance-2026-manage-nic-costs/). On a fairly typical £35,000 salary, that’s roughly an extra £4,500-£4,800 a year in employer NI alone, before pension contributions or anything else is added (https://www.mjkane.co.uk/2026/05/20/employer-nic-increase-sme-impact/).

None of that is a reason not to hire. But it is a reason to be honest about what a “cheap and safe” hire actually costs, because it’s rarely cheap and it’s almost never safe. Nearly a quarter of SME employers surveyed by iwoca said they were planning to cut headcount specifically to absorb these changes, and over a third said they’d be slowing hiring plans altogether (https://www.lawdonut.co.uk/personal/news/national-insurance-rise-impacts-small-business-hiring-plans). Businesses are already thinking harder about who they put on the payroll. The question is whether they’re thinking harder about the right thing.

Junior isn’t actually the safe option

Here’s the part that gets missed. When a business hires below the level of seniority that the problem actually needs, it isn’t avoiding risk. It’s relocating it, usually to somewhere much more expensive to fix later.

The Recruitment and Employment Confederation puts the cost of a poor hire at manager level at more than £132,000, once you factor in lost productivity, management time, and the drag on the wider team (Source: Sage). CIPD data shows 41% of UK employers made a hiring decision in the last year they later regretted, most often because they hired under time pressure. That’s not a story about bad people making bad choices. It’s what happens when the pressure to “just get someone in” overrides the harder question of what level of experience the role actually calls for.

A junior marketer, however capable, hasn’t been hired to make judgement calls about positioning, resourcing, or where the next quarter’s budget should really go. They’ve been hired to execute. So the business ends up with someone producing activity, while nobody is actually deciding what that activity is for. Campaigns run, content goes out, the calendar looks full, and eighteen months later leadership is still asking the question they started with: why isn’t this working?

That gap between activity and ownership is expensive precisely because it’s invisible. It doesn’t show up as a bad hire on paper. It shows up as flat growth, a marketing spend nobody can fully account for, and a strategic delay that compounds every quarter it isn’t corrected.

What’s actually driving the shift toward fractional leadership

This is the backdrop against which Fractional Marketing CMO hiring has grown so sharply. UK Department for Business and Trade research already found 62% of mid-sized businesses naming recruitment and access to senior skills as a key barrier to growth, and the Scaleup Institute’s most recent Annual Review found 55% of UK scaleups cite difficulty accessing senior leadership talent as a top barrier. Against that backdrop, the fractional model has moved from alternative to mainstream extremely quickly: LinkedIn profiles describing fractional roles grew from around 2,000 in 2022 to over 110,000 by early 2024 (Source: Vendux) and Heidrick & Struggles’ High-End Independent Talent Report found a 151% increase in C-suite interim engagements since 2021.

The commercial logic is straightforward once the true cost of a full-time senior hire is on the table. A retained Fractional Marketing CMO engagement typically lands around 10-20% of the cost of a full-time CMO once salary, employer NI, pension and recruitment fees are all counted (source: Oneumbrella). That’s not a discount on quality. It’s the same calibre of thinking, scaled to the number of days a business genuinely needs it, rather than five days a week whether the business has that much for them to do or not.

The real question isn’t “can we afford it” – it’s “can we afford not too”?

The instinct to wait on senior marketing leadership almost always comes from a good place: protect cash flow, don’t overcommit, prove the model first. Those are reasonable instincts in isolation. But applied to marketing leadership specifically, they tend to produce the opposite of what they’re aiming for.

Because the actual cost isn’t the day rate or the salary. It’s the compounding cost of not having anyone in the room who can look at the whole picture, say “this is what we should be doing and this is what we should stop,” and be accountable for the outcome. A junior hire can’t carry that. An agency, however good, is usually executing against a brief someone else was supposed to have set. Without someone senior enough to own the decisions, both end up doing a lot of work in the wrong direction, or the right work with no coherent thread running through it.

That’s the diagnosis worth sitting with before the next hiring decision gets made. Not “what’s the cheapest way to get some marketing activity going,” but “who is actually going to own this, and are they senior enough to be trusted with the decisions that matter.” Get that right, even for two days a week, and the rest tends to follow. Get it wrong, and the bill arrives later, quietly, dressed up as slow growth.
