If you spend any time looking at Companies House filings for independent UK recruitment businesses, a clear pattern emerges.
There is a large cohort of firms, well-run, respected, often market-leading in their niche, that built themselves to £15–30m NFI and then, broadly speaking, they simply stop. They haven’t collapsed, nor are they sold, they’ve just stopped growing in any meaningful way. Revenue charts that look like a horizon line rather than a trajectory. What causes this 20 year plateau? Let’s take a closer look.
What the numbers actually show
The UK recruitment sector is enormous with over 825 companies turning over more than £5m annually. But scale within that group is heavily skewed. A small number of businesses account for a disproportionate share of NFI, and beneath them sits a long, wide band of firms stuck in the same revenue corridor they were in a decade ago.
Look at a company’s revenue CAGR over a 10–15 year window and you often find something like this: strong growth through the early years, a peak around the £10–15m NFI mark, and then a flattening. Some of these firms will show marginal year-on-year increases that, when adjusted for inflation, represent no real growth at all. They are, in effect, treading water while their founders believe they are swimming.
The Recruiter’s annual Hot 100 list provides a useful reference point. The 2025 list showed combined NFI of £1.4bn across the top 100 most profitable UK firms, with NFI per employee rising to an average of £136,186, a 4.6% year-on-year increase. But headline productivity gains across the top 100 can mask the reality that firms outside that cohort are often delivering less NFI with more people than they were five years ago.
The PageGroup comparison is instructive
PageGroup was founded in 1976 as a single-discipline firm operating from one UK office. By the mid-1980s it had opened internationally. By 1996 it was listed on the London Stock Exchange. In 2022, it reported revenue of £1.67bn.
Hays followed a similar arc, founded in 1867, IPO in 1989, now operating across 33 countries with revenue of £6.6bn in 2025.
The obvious response is that these are outliers, businesses with access to capital markets, external investment, and a growth model that most independent firms neither want nor need. That is fair. But the comparison is still useful, because it surfaces the question that founders rarely ask themselves directly: at what point did we stop making deliberate choices about growth and start accepting the ceiling we had built?
PageGroup’s own 2024 annual report is candid about its model: ‘when market conditions tighten, these entrepreneurial, profit-sharing teams reduce in size, largely through natural attrition.’ That structural flexibility, and the willingness to build it deliberately, is one of the things that separates firms that scale from firms that plateau.
Why does the plateau happen?
There are structural reasons and there are leadership reasons, and they tend to reinforce each other.
Structurally, many firms in the £15–30m NFI range are still essentially founder-dependent. Revenue is concentrated in long-standing client relationships that belong to the founder or a small group of senior people who were there from the start. The business has grown around those relationships rather than building the systems, management layers, and client diversification that would allow it to grow beyond them.
Hiring at this level also gets harder. The founders who built these firms were, typically, brilliant recruiters and relationship managers. The people required to take a £20m NFI business to £40m are often of a different profile: operators, managers, people who want to build teams rather than run desks. Finding them, affording them, and trusting them is a transition that a lot of founders never fully make.
On the leadership side, there is something more uncomfortable to acknowledge. Building a business to £15–30m NFI is a genuine achievement. It takes a long time and it is personally demanding. After a decade or more of that, many founders have reasonably moved into a different relationship with the business.
They are protecting what they have built, managing risk, maintaining income. The appetite for the disruption that real growth requires has diminished, even if the ambition has not. This is not a criticism. It is a human response to a long and difficult journey, but it does still have consequences.
The inflation problem
One of the quieter risks of the plateau is that many founders do not realise they are on one.
Revenue can drift upward in nominal terms, 3–5% a year, while actually declining in real terms once inflation is factored in. Margins compress as salary expectations rise and as clients push back on fees. The business looks roughly similar to how it looked five years ago, which is easy to read as stability rather than stagnation.
A simple test: take your NFI over the last ten years, adjust for CPI, and look at whether the trend is genuinely positive. For a significant number of firms in this band, it will not be. Real NFI growth of 2% per year is not growth, it is a slow contraction in purchasing power and competitive position.
What tends to follow
RSM’s 2025 year-in-review of recruitment M&A makes for interesting reading in this context. The firm recorded 74 completed transactions in the UK sector in 2025, a 17.5% increase on 2024, which itself saw a 27.6% rise from the lows of 2023.
RSM noted that while strategic trade buyers remain dominant, ‘other buyers have taken advantage of semi-distressed opportunities from weaker firms.’ That phrase is doing a lot of work. Weaker firms, in this context, often means businesses that have plateaued where growth has stalled, where founder fatigue has set in, and where the owner eventually reaches a point where an exit, even on imperfect terms, feels preferable to another five years of the same.
The pattern is consistent. Plateau tends to precede sale, and prolonged plateau tends to precede distressed sale. Founders who hold on through a period of real decline, because they believe conditions will improve, because they are not ready to let go, or because they have not thought clearly about the timeline typically achieve worse outcomes than those who make a deliberate decision while the business still has momentum and options.
The M&A advisory firm Boxington, which focuses specifically on exits for founder-led businesses in the human capital sector, has noted publicly that the quality of deal execution increasingly depends on sellers being ‘data-ready’ and able to demonstrate genuine resilience and growth trajectory to buyers. A firm that has been flat for a decade has a harder story to tell, and typically a smaller field of buyers willing to tell it with them.
Three questions worth considering
If you are running a recruitment firm in the £15–30m NFI range, the data suggests it is worth asking yourself three things:
Have we actually plateaued, or does it just feel like it?
Pull ten years of real (inflation-adjusted) NFI data. Map your revenue CAGR against your headcount growth. The answer is usually in those two numbers.
Is this structural or is it leadership?
Are there genuine ceiling constraints, market size, margin pressure, client concentration or is the business still broadly capable of growth if the right people and decisions were in place? The honest answer to this changes what you do next.
Are we still growing in real terms?
Not in nominal revenue terms. In actual purchasing power, in competitive position, in the quality of clients and people. If the answer is no, the question becomes when you want to have that conversation and with whom.
In summary
The plateau is not a failure. Getting to £15–30m NFI as an independent business, in a sector as competitive as recruitment, is genuinely hard. But staying there without meaning to is a different thing and the firms that have made deliberate choices about what comes next have, consistently, ended up with better outcomes than those that simply waited. The data on this is fairly unambiguous, the question is whether founders are looking at it.
