The hidden job market in the UK

Agencies are a bigger part of UK hiring than many people realise. The Recruitment and Employment Confederation estimates the industry contributed £44.4 billion to the UK economy in 2023, with £10.5 billion of that from permanent placements. That is an industry built on filling roles for employers, plenty of whom never advertise those roles under their own name.

The typical agency advert is public but deliberately vague: "Our client, a leading financial services firm in Leeds, is looking for a management accountant." The job isn't hidden; the employer is. Agencies do this so candidates can't go around them, which is fair enough. It matters to you for two reasons. The same role may also be live on the employer's own careers site, where you can apply direct. And if two agencies, or an agency and you, both submit your CV for the same job, you have created a dispute over who earns the fee. The easiest way for the employer to settle it is to drop you.

Our rule of thumb: if you found the role on the employer's own site first, apply direct. If an agency brought it to you first, or clearly knows the hiring manager (they can tell you who is interviewing and why the role is open), let them submit you. In fields where agencies are common, such as accountancy, finance and IT contracting, two or three specialists who know your market are worth more than ten generalists sending you the same adverts.

Most UK job hunts start on Reed or Indeed. Reed calls itself "the UK's #1 job site" and, when we checked on November 7, 2026, said it had around 200,000 jobs available; the same group also runs Reed Specialist Recruitment, an agency in its own right. Indeed pulls in listings from employer sites and agencies alike. Both are good at volume. Where they lag is timing, since a board only picks a role up after the employer posts it. They can also miss smaller employers whose roles sit on a Workable or Dayforce careers page.

For scale, the ONS estimated 691,000 UK vacancies in July to September 2026, down 21,000 on the quarter before. Our 8,200 or so UK postings are a sample shaped by what our users search, not a census, but the mix of sources says a lot.

In this snapshot Workable made up about 4% of UK postings against under 2% across our whole feed, and Ashby about 2% against about 1%. Both are systems many smaller companies use, the kind of employer that may not pay to advertise on a big board. You can search those systems yourself with the strings in our ATS job search guide.

Among the roughly 1,300 UK postings that stated pay, the median was about £41,000, with the middle half between about £30,000 and £65,000. That covers only postings that state a salary, so treat it as a rough guide.

The top of that list was retail, leisure and hospitality: B&Q, Marks and Spencer, PureGym, Morrisons, The Gym Group, Tesco and Mitchells & Butlers all posted heavily. If you want store, gym or pub roles, their own careers sites are the first place to look, with alerts switched on. For office roles the list thins out fast, which is why a target list of your own matters more than any ranking.

Graduate schemes are the most public part of the UK market, and the most crowded. The Institute of Student Employers found that employers in its survey received an average of 140 applications per graduate vacancy, a record when it was published in 2024. A year later ISE reported graduate vacancies down 8% as apprenticeships grew.

We would apply to the schemes you really want, early in their window, then spend the rest of your effort on direct graduate roles at smaller firms. Those firms hire when a need appears rather than on a calendar, their roles often sit on a Workable or Ashby careers page, and they can close within weeks.

A speculative application is a CV and a short email sent to an employer that hasn't advertised. It's a well-worn route in the UK and it works best with small and mid-size firms, where the person reading is often the person hiring. Keep it short, name a specific reason you picked them, and attach a CV that fits on two pages. Send it to a named manager, not a generic careers inbox.

HiddenJobs UK (hiddenjobsuk.com) makes the same basic case we do and is built only for the UK. When we checked on November 7, 2026, it described itself as watching the careers pages of UK companies, re-checking them twice a day, and offering a filter for employers on the Home Office register of licensed visa sponsors. That sponsor filter is useful if you need a Skilled Worker visa. Coverage outside London looked thin in the pages search engines had indexed: its London page listed 1,154 live jobs, while its Wales page listed 16 and its East of England page 22.

Neither of us can show you the referral or speculative side, and you should be sceptical of anyone who says they can. For the bigger picture on what is and isn't hidden, including where the famous "70% of jobs are never advertised" line comes from, see our guide to the hidden job market. And if an agency advert keeps reappearing week after week, our ghost jobs checklist will help you decide whether it's worth a call.
