UK live vacancies climbed for a fourth consecutive month in May 2026, rising 2.85% month-on-month to 799,737 according to Adzuna's job-market index. On the surface, that reads as a hiring market finding its footing. Dig into the sector breakdown, the ONS (Office for National Statistics) business-survey figures, and the pay data running beneath the headline, and the picture becomes considerably more complicated: advertised salaries are down 1.7% year-on-year, graduate openings have collapsed 42.1% over the same period, and the ONS puts the underlying vacancy trend firmly in contraction.

For anyone making a career decision this summer, or planning headcount for the second half of the year, the question is not whether the number is real. It is which number you should actually be steering by.

The two contradictory numbers, side by side

Adzuna's index counts every live job advertisement posted online across the UK. Its May 2026 reading of 799,737 represents a 1.4% rise year-on-year as well as the fourth successive monthly increase. The ONS, which derives its vacancy estimates from a direct survey of UK employers rather than ad listings, produced a markedly different figure for the overlapping period: approximately 707,000 vacancies in the March-to-May window, down 19,000 (2.6%) on the previous quarter and the lowest reading since the early stages of the pandemic recovery in 2021. At that level, there were roughly 2.5 unemployed people for every ONS-measured vacancy.

Both measures are methodologically defensible. Adzuna captures the full volume of posted adverts, including roles that are reposted after expiry, syndicated across multiple aggregator boards, or left live well after the position has been filled. The ONS captures employer-reported intent at a single survey moment. The gap between the two is itself the most informative signal available: advert volume is recovering faster than genuine hiring demand. The CIPD (Chartered Institute of Personnel and Development), which tracks employer sentiment through its quarterly Labour Market Outlook, has noted in recent surveys that many organisations are maintaining recruitment activity at a lower conversion rate than in 2022-23, which is consistent with precisely this divergence.

Where the headline number hides sector weakness

The 800,000 aggregate conceals sector-level swings large enough to determine whether a given jobseeker is operating in a buyer's or seller's market. Adzuna's May breakdown shows three major sectors posting deep annual declines: Healthcare and Nursing down 33.3% year-on-year, Hospitality and Catering down 32.2%, and Logistics and Warehouse down 31.8%. These are not peripheral verticals; they account for some of the largest concentrations of frontline employment in the UK economy, and the combined contraction means that a significant proportion of the workers who might be encouraged by the headline figure are, in practice, searching in a market that has shrunk by roughly a third in twelve months.

At the other end of the distribution, Domestic Help and Cleaning vacancies ran 382% above their May 2025 level, with advertised salaries up 9.3% on the year to an average £30,799. That is a genuine positive for workers in that segment. It is of limited relevance to a registered nurse or an HGV driver whose sector is contracting sharply.

Graduates are bearing the steepest pressure. Adzuna recorded 8,398 graduate vacancies in May 2026, a fall of 9.6% from April and 42.1% from May 2025, the sharpest annual decline the index has recorded for that category. Average advertised graduate salaries slipped to £25,773 from £26,126 the previous month. The Resolution Foundation has documented the long-run effect of entering a weak labour market on lifetime earnings trajectories, and a 42% drop in entry-level openings in a single year is the kind of shock those models flag as persistent rather than transitory.

For employees and jobseekers

The practical implication of May's data for anyone actively searching is: more adverts to apply to, but with weaker salary bargaining leverage than the headline vacancy count implies. Three adjustments are worth making now rather than waiting for the market to clarify.

Check your sector's trajectory, not the national aggregate. A 1.4% annual rise across all UK vacancies is statistically close to flat, and it masks annual falls of 30-plus per cent in three major sectors. Before anchoring your expectations to any figure, look at vacancy volume in your specific field over the past six months. The ONS Annual Survey of Hours and Earnings (ASHE), which HMRC and ONS publish jointly and which covers pay by occupation and sector, provides a more granular pay baseline than a single national average.

Anchor salary expectations on what is being advertised now, not what was on offer in 2023. Advertised pay is down 1.7% year-on-year in cash terms before adjusting for inflation. If you are weighing a move from a current role, compare any incoming offer against live postings for the same job title in your region today. ACAS (Advisory, Conciliation and Arbitration Service) guidance on pay negotiation is worth reviewing if you are uncertain how to frame a counter-offer in a market where leverage has shifted.

Apply faster and more precisely. Competition for roles eased marginally in May, with 2.14 applicants per vacancy against 2.22 in April, but the ratio remains tight. A targeted application submitted within 48 hours of a role going live consistently outperforms a broader, slower approach. Sector focus matters more than volume here.

For HR and hiring leaders

A reading of the Adzuna headline alone could lead a reward or talent team to budget for a tightening candidate market in the second half of 2026. The ONS employer-survey figure points in the opposite direction: reported demand is at its lowest since early 2021. Several operational adjustments follow from taking both signals seriously.

Audit the currency of your live adverts. Part of the structural gap between the Adzuna count and the ONS estimate reflects roles that remain posted past their close date or that are syndicated to multiple boards without a coordinated withdrawal. If your careers page and aggregator listings carry stale postings, you are overstating your firm's hiring activity to candidates, distorting your own funnel conversion metrics, and eroding the candidate trust that makes future recruitment easier. A monthly clean-up is a low-cost, measurable fix.

Re-baseline pay bands against current market data before approving offers. With advertised salaries down 1.7% year-on-year nationally and sector-level declines running deeper than that in Healthcare, Hospitality, and Logistics, a pay-band review conducted on last year's ASHE figures is already out of date. The CIPD's annual Reward Management Survey, which tracks profit-share take-up and pay-review cycles across UK organisations, is a useful cross-reference alongside ONS ASHE when recalibrating bands, particularly for roles below £35,000 where the year-on-year compression appears sharpest.

Take the graduate vacancy signal seriously as a pipeline and reputational issue. A 42% annual fall in graduate vacancies is not simply a reflection of cost control. Graduates who search without success in 2026 retain a clear memory of which employers were visible and accessible and which were not. Withdrawing a graduate programme to protect a budget line in the short term carries a three-to-five year pipeline cost that rarely appears in the original business case. For organisations subject to the FRC Corporate Governance Code, Provision 40, which requires remuneration committees to consider the alignment of executive pay with wider workforce outcomes, the treatment of entry-level and graduate cohorts is increasingly part of that governance conversation.

The honest read on May's numbers

A fourth consecutive monthly rise in Adzuna's vacancy count is a genuine positive, and a slight improvement in the applicant-to-vacancy ratio points in the right direction. Those signals are real. What sits alongside them is equally real: pay is falling in cash terms, the ONS employer survey is contracting toward its lowest reading in five years, three of the UK's largest frontline sectors have shed roughly a third of their advertised openings over twelve months, and graduates are entering what the Adzuna index identifies as its worst recorded entry market.

For a jobseeker, May's data argues for moving quickly and anchoring negotiations on current sector-level pay data from ASHE rather than on the national headline or on market memory from two years ago. For a hiring team, it argues for treating this as the beginning of a cautious thaw rather than a confirmed recovery, and for acting accordingly on advert hygiene, pay-band calibration, and graduate pipeline investment. The 800,000 figure is a useful starting point for that conversation. It is not a substitute for the conversation itself.
