Salary benchmarking looks simple until two reputable sources give different answers. A recruiter may see one figure for a role on a job board, another in a salary guide and a third from employee-reported data. The instinct is often to ask which source is correct. A better question is what each source is actually measuring. Different datasets can use different job titles, industries, locations, seniority levels, pay components and collection methods. A national average based on advertised salaries is not the same thing as an employee-reported base-salary median, and neither is automatically the correct number for one vacancy. For recruiters and employers, the skill lies in understanding the denominator before using the benchmark.
Different salary sources measure different populations
One source may analyse advertised vacancies, another may collect salaries reported by employees, while a third may survey employers. Those populations can produce different figures even when the job title looks identical.
For example, Reed’s recruitment salary data has shown an average Recruitment Consultant salary of around £36,166, with a low around £33,889 and a high around £39,461 across the roles captured in that dataset. Reed’s broader Recruitment category has also produced a different average, around £37,026, because the category includes a wider mix of positions.
Glassdoor, by contrast, has reported an average base salary for UK Recruitment Consultants around £25,000, with a typical base range of roughly £22,000 to £29,000, plus additional pay that can include bonuses and commission.
Those figures should not be treated as direct contradictions. Reed may be drawing heavily from advertised vacancies and a particular current job mix. Glassdoor relies on employee-reported compensation and separates base from additional pay. The underlying populations are different.
The advantage of comparing several benchmark types is that employers gain a broader view of the market. The disadvantage is that averaging them together can create a number that belongs to none of the original datasets.
Base salary, total pay and commission need to stay separate
Recruitment roles are especially difficult to benchmark because compensation often includes commission or bonus. A base salary of £25,000 can produce a much higher total annual income if the employee performs strongly. Another employer may offer a higher base with a less aggressive commission structure.
This means a vacancy advertised at £35,000 may not be comparable with an employee-reported base salary of £25,000 if the first figure includes expected variable pay or reflects a more senior role.
The advantage of total-pay data is that it captures the real economic reward available to employees. The drawback is volatility. Commission and bonuses can vary widely between individuals and years, making the average less stable.
Base salary is easier to compare but can understate the attractiveness of a role where variable compensation is substantial. Employers should therefore benchmark base, on-target earnings and actual realised total pay separately where possible.
For recruiters, this also affects candidate conversations. A candidate earning £28,000 base plus £15,000 commission is not necessarily moving for a £35,000 base role if the new commission scheme is weaker.
Location, seniority and specialism can move the benchmark sharply
A UK-wide figure can hide major regional differences. Salaries in London and the South East may be higher than in other regions because of labour-market competition, cost structures and employer concentration. Remote work can blur those boundaries, but geography still matters in many sectors.
Seniority is equally important. A Recruitment Consultant, Senior Recruitment Consultant, Principal Consultant and Recruitment Manager may all appear in a broad salary dataset but represent very different levels of responsibility and earnings.
Specialism also changes market value. Recruiters working in technology, finance, healthcare or executive search may have different compensation patterns from generalist recruiters or high-volume temporary staffing consultants.
The benefit of national averages is simplicity. They provide a quick reference point. The drawback is that they can become misleading when applied to a specialised role in a specific location.
Employers should therefore narrow benchmarks where possible by region, level and specialism. A national average is useful for orientation, not necessarily for setting the final salary.
Data freshness and sample design affect reliability
Salary markets can move quickly, especially in sectors experiencing shortages or downturns. A benchmark based on data collected two years ago may be less useful than a current but smaller sample.
Job-board data can respond quickly to changes because new vacancies appear continuously. Employee-reported data may reflect actual realised pay but can lag if reports are older or unevenly distributed across employers.
Sample size also matters. A figure based on thousands of records is generally more stable than one based on a handful, but a large sample is not automatically better if it mixes many different roles together.
The advantage of large aggregated datasets is statistical stability. The disadvantage is loss of specificity. Smaller targeted datasets may better represent a niche market but have more sampling noise.
Recruiters should therefore check the date, sample size, job definition and whether the reported figure is mean, median, range or estimated total compensation before quoting it to a client.
How employers should build a practical salary benchmark
The strongest approach is to begin with the role itself rather than with a website. Define responsibilities, level, location, required experience and expected variable pay. Then choose benchmarks that resemble that role as closely as possible.
Use each source for what it does well. Job-board data can show current advertised market demand. Employee-reported platforms can show realised base and total pay. Internal payroll data can reveal what the organisation already pays. Recruiter experience can add context about current candidate expectations.
The benefit of combining these perspectives conceptually is better judgement. The drawback is that they should not be merged mechanically into one synthetic average. Different sources should remain labelled according to their own methodology.
Employers should also think in ranges rather than one exact number. A salary band can reflect differences in experience and performance while still maintaining internal fairness. Clear ranges also make recruitment conversations easier and reduce the risk of paying according to negotiation strength alone.
The practical conclusion is that salary benchmarks are tools, not answers. When figures disagree, that is often because the sources are measuring different things. The right response is not to force them into agreement but to understand the definitions and select the benchmark that best matches the vacancy.

Supporting evidence: salary benchmarks differ because the underlying measures differ
Reed's current UK Recruitment Consultant salary page reports an average of about £36,338, based on current jobs on Reed, with a displayed range of roughly £34,080 to £39,903. Glassdoor's UK Recruitment Consultant page separately reports an average base pay of about £25,000 and average additional pay of about £7,000.
Those figures should not be averaged together or treated as if one disproves the other. Reed is presenting salary data derived from jobs in its own current listings, while Glassdoor separates base pay from additional compensation and relies on its own salary-reporting dataset. The populations, timing and pay definitions are different.
This is why recruiters should compare like with like: base salary with base salary, advertised salary with advertised salary, and total or additional pay only where the same compensation components are included. Geography and seniority matter too; both platforms show substantial variation once the search is narrowed.
Evidence boundary: these are live commercial salary datasets and can change as new vacancies or user reports are added. They are useful market indicators, not statutory pay scales or a substitute for role-specific internal benchmarking.
