Key takeaway

UK professional and technical vacancies are falling more than twice as fast as the total.

UK vacancies fell to 691,000, on the early estimate, in July to September, down 37,000 (5.1%) on the year, and lower than at any point outside the pandemic since July to September 2014, the Office for National Statistics (ONS) reported on 20 October⁠¹. Vacancies in professional, scientific and technical activities, a sector heavily exposed to AI, fell 11.6% on the year, more than double the economy-wide rate.

In September the ONS had shown that sector adding jobs while advertising fewer of them. In July the headline series had briefly risen to 712,000, its first quarterly rise in this briefing's tracking; the new early estimate sits 21,000 below that.

Deep Analysis

In plain English

A vacancy is a job that an employer is actively trying to fill. Britain's statistics office, the Office for National Statistics (ONS), counts them every month by asking businesses. The latest count shows fewer open jobs than at any time since 2014, apart from the Covid pandemic. The fall is steepest in professional work such as law, accounting, consulting and research. Those jobs involve tasks that AI tools can now do, but higher employer costs and a slower economy also reduce hiring.

Deep Analysis

Root Causes

Entry-level hiring became dearer in April 2025, when the Employer National Insurance rate rose and the threshold at which it starts was cut. The threshold change weighs most on low-paid and part-time posts, which are the roles young applicants fill first.

The ONS's Labour Force Survey has suffered collapsing response rates since 2023, which makes household-based youth employment figures unreliable. The business-based vacancy survey has become one of the steadier labour market series, so it carries more of the analytical weight than usual.

Professional services firms hire graduates into research, drafting and analysis roles, the tasks generative AI tools most readily perform, so a sector-specific fall is where an AI effect on hiring would show first.

What could happen next?

Consequence
Graduate entry into UK professional services is likely to stay tight through the 2027 recruitment round if sector vacancies keep falling at twice the national rate.
Meaning
A sector adding jobs while advertising fewer of them points to lower staff turnover and fewer entry posts, the hiring-side pattern central banks in Canada and France have measured.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: After the 2001 US recession, output recovered while hiring stayed weak, and New York Fed economists Erica Groshen and Simon Potter argued in 2003 that firms were restructuring permanently rather than waiting to rehire. Low vacancies in a growing sector fit the same pattern of structural rather than cyclical slack.

Counter-parallel: The 2014 comparator itself came on the way up: UK vacancies at that level were climbing out of the 2008-09 recession and rose steadily for the next four years. Today's figure sits at the same height on a falling path.

The immediate figures show 2.4 unemployed people for every vacancy in June to August, against 2.5 in March to May, and vacancies down 21,000 (2.9%) on the previous quarter. Professional services adverts fell 9,000 on the year.

Structurally, the sector's 11.6% fall in vacancies is more than double the economy-wide 5.1%. If that persists while employment grows, the sector is filling posts by keeping and stretching existing staff, which leaves fewer first jobs for graduates.

Consensus view: UBS chief economist Arend Kapteyn has tied record-low white-collar turnover partly to "AI fear" . Fewer people quitting means fewer replacement adverts, which fits a vacancy fall concentrated in professional services rather than spread evenly.

Counter-view: The ONS's own workforce figures showed professional, scientific and technical firms adding 51,000 jobs on the year in its September release, even as their adverts fell. On that evidence employment in the sector is still growing, and the Employer National Insurance rise of April 2025 explains weaker hiring across every sector without any AI effect.

Key tension: Whether fewer professional adverts mean fewer entry-level posts for new graduates, or simply fewer leavers to replace in firms that are still growing.

Different Perspectives

Korea's four largest banks, as reported by News1

KB Kookmin, Shinhan, Hana and Woori rehired 1,013 retirees last year, equal to 79.1% of their graduate intake, according to News1. Graduates face a smaller entry intake while returners take fixed-term credit-screening roles at lower pay, News1 reports.

High Court of Justice of Madrid

The court's employment chamber ruled in judgment 864/2026, dated 8 October and made public in early November, that introducing AI is not on its own a ground for dismissal. Employers must prove AI's effect through the four causes the Workers' Statute already lists.

Singapore Ministry of Manpower

The Singapore Ministry of Manpower put third-quarter retrenchments at 4,800, concentrated in information and communications, financial services and manufacturing, with business reorganisation the main driver. Its release does not mention AI.

Challenger, Gray & Christmas

Challenger reported on 5 November that market and economic conditions overtook AI as the leading stated reason for 2026's US job cuts, at 130,531 against 121,401. AI was cited for 1,265 cuts in October, its lowest month of the year.

Office for Budget Responsibility

The OBR's 28 October outlook showed output per worker in information and communication growing 7.6% a year, yet kept AI's boost to UK productivity at 0.2 percentage points a year. It does not attribute the faster growth to AI.

Central Bank of Ireland

Governor Gabriel Makhlouf said on 2 November that AI investment has supported Irish activity and flagged the debt financing behind it as a financial-stability risk. On jobs, he named skills bottlenecks and mismatches, not job losses.
