What Kind of HR Support Does Your Business Actually Need?
It's one of the most common questions growing businesses ask. Do we need an HR consultant? Should we be hiring someone in-house? Do we need both? Is a retained partnership the right move, or is it a one-off project?
The honest answer is that it depends entirely on your growth stage — not on headcount, and not on how you'd prefer to work. Get the type of support wrong and you either overspend on the wrong thing, or underinvest at precisely the moment the business needs it most.
Here's how the need changes as a business grows, and what the right support looks like at each point.

When the foundations don't exist yet
Most businesses at an early stage of growth have someone holding HR — usually the founder, sometimes a trusted generalist or office manager who became the go-to person for people questions. They're doing good work with what they've been given. The problem is that what they've been given is often no strategy, no structure, and no foundation to build from.
At this stage, the gap isn't operational. The business doesn't need an HR coordinator managing day-to-day queries. It needs clarity: what kind of business is this becoming, what does it need from its people to get there, and what structures and habits need to be in place to make that possible?
The Employment Rights Act 2026 has made this more urgent for a lot of founders. Unfair dismissal protections from day one of employment, tighter flexible working obligations, and more complex rules around zero-hours contracts mean that holding HR on instinct carries more risk than it did two years ago.
Yellow works at this stage as an external People Director — building the strategy, the frameworks, and the foundations alongside whoever is holding people in the business. The goal is a people infrastructure the business can grow into, not one it's already grown out of.

When the practices are building but not yet consistent
As a business gains momentum, HR practices start to take shape. There's usually more structure than there was — some policies, a clearer approach to hiring, some kind of performance framework. Progress is visible.
But consistency is the challenge. Standards vary across teams. Culture depends too much on individual managers. The People function — whether that's a generalist, a small HR team, or still the founder — is absorbing the full operational load, and the strategic layer is the thing that keeps getting pushed back.
This is where Yellow typically works as a retained or fractional partner. Not to replace whoever is holding people, but to work at the strategic level alongside them — leadership alignment, culture in daily practice, scalable systems that work at the next stage, not just this one. The People team handles operations. Yellow handles the layer that keeps them pointed in the right direction.
47% of UK small businesses now use some form of external HR support, up from 38% in 2022. Much of that growth is here — businesses that have an internal HR function but need strategic capacity they can't yet justify hiring full-time.

When the fundamentals are strong and optimisation is the goal
Some businesses reach a point where the people strategy is working. Culture is defined and largely consistent. Leadership is capable. Recruitment is structured. The challenge shifts from building to optimising — using data to drive decisions, strengthening accountability, refining the employee experience so it fuels performance rather than just maintains it.
At this stage, the right support is usually project-based. A specific piece of work with a clear outcome: a leadership development programme, a restructure, a compensation review, a culture audit ahead of significant growth. Yellow works here through targeted strategic projects — focused, time-bound, with a clear return.

When the business is ready to scale and the people infrastructure needs to move with it
The most sophisticated stage is also, paradoxically, the one where businesses are most at risk of getting people wrong. When a business is ready to scale — investment secured, acquisition planned, new markets opening — the commercial side moves fast and the people side gets treated as something to sort out afterwards.
It shouldn't. The businesses that scale without people problems are the ones where the people infrastructure is built for the next stage before the growth happens, not during it. Leadership capability for a larger organisation. Culture frameworks that hold when the founding team isn't in every room. Recruitment and onboarding that works at volume.
Yellow works at this stage as a strategic partner — guiding and delivering the people elements that make change successful. The focus is on what the business is becoming, not just what it is now.

The question isn't consultant or in-house. It's what does the business actually need at this stage — and is the support in place structured to deliver it?
Yellow's Growth Stage Assessment is a three-minute diagnostic that tells you exactly where your people strategy stands: what's working, what's stretched, and where to focus next. If you're not sure which of these stages your business is in, that's the right place to start.
