- 5 benchmarks matter, not the UK 34% average alone (CIPD): industry, role, business size, tenure at exit, and voluntary/involuntary composition
- Industry is the strongest single predictor. Manufacturing ~11%, professional services 10-15%, tech 20-30%, hospitality 50%+
- Small UK businesses run higher turnover than large ones. A 22% rate in an SME is often within the normal 18-30% band, not a crisis
- Above sector benchmark? Try the SA comparison. UK teams cost 40-60% more to run and lose people faster than SA teams for the same roles
Employee turnover rate is the percentage of your workforce that left during a given period, usually a year. Calculating it takes minutes: leavers divided by average headcount, multiplied by 100. Benchmarking it is where the useful analysis begins.
The problem with benchmarking against a single national figure (like CIPD's 34% UK average) is that the range across industries, roles, and business types is enormous. A 20% rate is exceptional in hospitality and worrying in professional services. A 15% rate is normal for a growing technology business and unusual for a small law firm. Comparing your rate against the wrong benchmark can send you in the wrong direction on retention decisions.
This guide walks through the five benchmarks that matter for UK businesses in 2026: industry, role level, business size, tenure at exit, and voluntary versus involuntary composition. It shows what each benchmark looks like for typical UK employers, what your rate probably means once you have compared it against the relevant one, and what the cost implication is if your rate sits above the benchmark for your context.
The employee turnover rate formula: a quick refresher
Employee turnover rate = (Number of leavers ÷ Average headcount) × 100
For a company with an average headcount of 51 and 8 leavers over the year, that returns (8 ÷ 51) × 100 = 15.7%, expressed as a turnover percentage over the annual period. For the full component-by-component breakdown, see our sibling guide, How to Calculate Employee Turnover.
The UK national average and its limits
The UK employee turnover rate averages around 34% per CIPD's Annual Population Survey analysis. That figure breaks into approximately 27.4% of employees moving to another employer within the year, plus a further 6.6% who leave the workforce entirely. For those who leave the workforce entirely, these reasons include retirement, study, long-term sickness, or caring responsibilities. Not everyone in the 34% figure is going to a competitor. About four in five are.
For most UK businesses, benchmarking your rate against 34% is broadly useless. The figure blends:
- Shift-based hospitality workers with tenure-track finance professionals
- Entry-level retail with C-suite executives
- Seasonal agricultural work with legal partnerships
Your business is not the UK national average, and neither is your team.
The useful benchmarks come one level down. Industry, role level, business size, tenure profile, and voluntary composition each tell you something different about what your rate is and is not saying. A good diagnostic works through all five.
By industry
Industry is the single strongest predictor of what "normal" turnover looks like. A 20% turnover rate in hospitality is exceptional. The same rate in a UK law firm is a serious problem. The variation between sectors is enormous.
The pattern behind the sector variation is structural, not accidental. Hospitality and retail rely on shift-based, minimum-wage-adjacent, part-time and student workforces where turnover is baked in. Manufacturing has ageing workforces with skill shortages that make trained workers hard to replace and hard to move. Finance has defined career ladders, high compensation, and specialist skills that keep people in place. Technology sits in the middle: relatively high compensation with a competitive market that keeps engineers moving between employers every 2-3 years.
If your business does not fit any of these cleanly (agencies, boutique consultancies, specialised services), start with the closest analogue and adjust based on what you know about your dynamic. An advertising agency typically runs higher than a strategy consultancy. A fintech typically runs higher than a traditional bank. A boutique law firm typically runs lower than a corporate legal services provider. For the full sector-by-sector breakdown including sub-sectors, see our sibling guide, Employee Turnover Rates by Industry (UK 2026).
By role and seniority
Within any industry, turnover varies significantly by role level. Junior roles have consistently higher turnover than senior roles across every sector. This is because early-career people are more mobile, more likely to test different roles and employers, and less anchored by pension entitlements, family, or property.
If your calculated rate is 25% and you are in professional services (industry benchmark 10-15%), the answer to "is this a problem?" depends heavily on where the 25% is landing. 25% concentrated in your entry-level cohort is normal; 25% concentrated in your senior team is a serious issue. Segmenting by role changes the diagnostic entirely.
By business size
Business size shapes turnover patterns in ways many UK founders do not anticipate. Small businesses typically run higher turnover than large employers, and the reasons are structural rather than management failures.
UK small businesses (under 50 employees)
Typically report voluntary turnover between 18% and 30% across knowledge-work sectors. The reasons:
- Fewer available career progression paths (there is often nowhere to go internally after 2-3 years)
- Less competitive benefits packages compared to larger employers
- More concentrated role dependencies (losing one person hurts more)
- Higher exposure to compensation drift as market rates move faster than SME budget cycles can respond
UK medium-sized businesses (50-250 employees)
Typically report voluntary turnover between 12% and 22%. The middle range benefits from more available progression paths, better benefits infrastructure, and enough HR capacity to run structured retention programmes. Turnover pressure at this size tends to concentrate in functions (usually sales or engineering) rather than spread across the whole business.
UK large businesses (250+ employees)
Typically report voluntary turnover between 8% and 18%. Larger employers can absorb turnover more easily, pay closer to market for critical roles, and offer broader progression paths. But the absolute number of leavers is higher, and the total replacement cost across a large workforce becomes a material P&L item even at percentages that look healthy.
For a UK founder running a business with 30-40 employees and comparing their 22% turnover rate to a 15% blended average, the conclusion "we have a retention problem" may be wrong. 22% is within the normal band for a UK SME. The retention lever exists, but the framing matters: you are not fixing a broken business; you are closing a natural gap between small-business economics and large-business retention infrastructure.
(8 ÷ 35) × 100 = 22.9%, rounded to 23%
Compared against the SME range (18% to 30% voluntary for knowledge-work sectors), this sits mid-band. Compared against the technology sector benchmark (20% to 30% overall), also mid-band. In isolation, that says the business is operating at normal SME-plus-tech levels.
But the headline rate is only the entry point. The tenure profile of those 8 leavers is what tells you whether 23% is a hiring problem, a progression problem, or normal churn. We work through this in the next section.
By tenure at exit
When people leave matters as much as how many people leave. The tenure profile of your leavers tells you which part of your employee lifecycle is broken.
Of the 8 leavers making up the 23% rate: 5 left in their first 12 months, 2 left in the 18-24 month window, and 1 left after 4 years.
62% of leavers concentrated in the first year signals a hiring quality issue, an onboarding problem, or a mismatch between the role as advertised and the role as experienced. The retention lever is not compensation or progression: it is fixing the entry funnel. The 25% in the 18-24 month window (2 of 8 leavers) is normal tech churn. The single 4-year departure is probably a circumstance rather than a systemic signal.
Voluntary vs involuntary composition
Not all leavers leave for the same reason. The ratio of voluntary to involuntary leavers is the fifth benchmark, and mixing them together makes both harder to see.
Voluntary turnover
Counts leavers who chose to leave: resignations, retirements, relocations, career pivots. This is the number that diagnoses retention. High voluntary turnover typically points to compensation, management, progression, or culture as the root cause.
Involuntary turnover
Counts leavers who did not choose to leave: dismissals for performance or conduct, redundancies, end of fixed-term contracts, mutual agreements that were commercially initiated by the employer. This is the number that diagnoses performance management and structural change. High involuntary turnover during a restructure is expected and, in a stable business, points to hiring standards or management culture.
Regretted turnover: the critical subset
Regretted turnover is a subset of voluntary turnover: leavers you would rather have kept. A 20% voluntary turnover rate where 90% of leavers are regretted is a serious retention problem. A 20% voluntary turnover rate where 40% are regretted is closer to normal churn. Tracking regretted separately is the single most useful diagnostic move that most UK businesses skip.
Voluntary turnover should sit at 3-5× involuntary turnover
For most UK knowledge-worker businesses. Involuntary turnover under 5% suggests the business is not actively managing performance. Involuntary turnover above 10% suggests either aggressive hiring standards, active restructuring, or a management culture that ends employment relationships rather than fixes them.
What your benchmarked rate means
If your rate sits at or below the industry benchmark and the role, size, tenure, and voluntary composition all check out, you are operating a healthy retention environment. The number itself might still be higher than you would like in absolute terms, but the underlying business is working.
If your rate is above the industry benchmark, the benchmark that is off tells you what to fix:
| Your pattern | Likely diagnosis |
|---|---|
| Above industry, concentrated in first year | Hiring quality issue |
| Above industry, concentrated in 18-24 month exits | Progression or compensation issue |
| Above industry, concentrated in senior roles | Management or strategic issue |
| Above industry, voluntary composition high with high regret | Retention problem |
| Above industry, involuntary composition high | Restructure in motion or hiring standards issue |
The point of running through all five benchmarks is that a single "we have a retention problem" conclusion is usually too broad to act on. The benchmark that is off tells you which lever to pull first.
Applying the right lever is the difference between a 12-month recovery and a 3-year one. For the full lever framework and the diagnostic-to-action mapping, see our sibling guide, How to Reduce Employee Turnover.
The best benchmark is your closest competitor
The single most useful benchmark is the turnover rate of your closest direct competitors, which is almost never publicly available. As a workable proxy, use the industry sector figure above and adjust for your business size and stage. Early-stage businesses typically run higher than mature businesses in the same sector. Weight the benchmark toward the roles that dominate your workforce.
For a comparison against the same roles in South Africa, the Legends EOR Salary Benchmarking Tool is the closest available data point. It shows current SA salaries in pounds sterling with the EOR fee included, letting you compare like-for-like against your UK team's cost.
The cost implication of your benchmarked rate
The turnover rate tells you how often people leave. Multiplying it against your salary base tells you what it is costing.
For UK businesses, the widely-cited range for replacement cost is 50% to 200% of the departing employee's annual salary. Oxford Economics' Cost of Brain Drain report puts the UK average cost of replacing an employee earning over £25,000 at £30,614, which adjusts to around £42,000 in 2026 pounds after inflation.
For a £45,000 mid-level role, applying the mid-range 75% rate gives around £34,000 in replacement cost per leaver. Two leavers a year in this bracket costs the business about £68,000, which for many UK SMEs is more than their entire training budget or their marketing spend. For the full component-by-component cost analysis, see our sibling guide, The Real Cost of Losing a UK Employee.
The 7-step benchmarking checklist
Once you have your rate, work through this order:
Calculate your rate
Leavers divided by average headcount, multiplied by 100. Our guide How to Calculate Employee Turnover covers the formula and components in full.
Find your industry benchmark
Use the sector table in Benchmark 1 above, or the closest analogue if your business type is not listed. Our guide Employee Turnover Rates by Industry (UK 2026) covers ten UK sectors with sub-sector detail.
Segment by role level
Compare the rate within each role tier (entry-level, junior, mid, senior, executive) against typical UK ranges. 25% concentrated in your SDRs is normal; the same rate in your senior team is not.
Check business size context
Small UK businesses run higher turnover than large employers as a structural norm. Factor this in before concluding you have a retention problem. The 18-30% band for small businesses is normal, not alarming.
Analyse the tenure profile
Where in the employee lifecycle are your leavers exiting? First year, 18-24 months, 3-5 years, or later? This step, more than any other, tells you which lever to pull first.
Separate voluntary from involuntary
Voluntary diagnoses retention. Involuntary diagnoses performance management and structural change. Mixing them makes both harder to see. Track regretted voluntary separately as a subset.
Interpret
Once all five benchmarks are compared, the pattern tells you which retention lever to pull first. The pattern-to-diagnosis table above maps the common patterns to their likely causes.
Skipping steps 3 to 5 is the most common diagnostic error UK founders make. The headline rate can look "normal" while the underlying composition tells a different story, as the worked example above illustrates.
What to do if your rate is above benchmark
The standard retention levers apply:
- Compensation review against current market
- Career progression audit
- Management capability check
- Workload sustainability diagnostic
- Cultural fit assessment
Improving any one of these will typically move the number over 12 months, particularly if the diagnostic (Benchmarks 3-5) has already told you which lever is most likely to be the constraint.
For UK SMEs where the cost of replacement is high because UK salaries are structurally high, a second option is worth considering: building teams in a labour market with structurally lower turnover and a lower salary base.
UK SMEs employing knowledge workers in South Africa through an Employer of Record typically report lower turnover than their UK equivalents for the same roles. The reasons are structural to the SA labour market: less job-hopping culture, longer tenure norms, and stronger workplace stability.
Two concrete cases from Legends EOR clients
For UK businesses running the benchmark comparison, this changes the maths in two directions at once. The salary base drops 40% to 60% on a like-for-like basis, and the turnover rate typically drops with it. Together, these compound.
None of this suggests offshoring solves every UK retention problem, or that SA hires never leave. Both statements would be untrue. But for UK SMEs whose turnover cost is high because UK replacement cost is high, offshore team stability is a legitimate second lever alongside the standard retention playbook.
