What Does ATS Stand For?
Applicant Tracking System Explained
A plain-English guide to what ATS means, how it filters UK job applications, and how to make sure your CV gets through.
ATS stands for Applicant Tracking System. It is software UK employers use to scan, sort and rank CVs against a job description before any recruiter reviews them. CVs that score below the employer’s threshold are typically filtered out automatically.

How an ATS Works (Step by Step)
When you submit a job application in the UK, your CV almost never goes straight to a human. It is processed by the employer’s ATS first. Here is exactly what happens between you clicking “Apply” and a recruiter seeing your name.
- 1
Submission
You apply through the employer’s careers site or a job board. Your CV and any application form fields are uploaded into the ATS database against that specific job.
- 2
Parsing
The ATS reads your CV file and extracts structured data — name, contact details, work history, education, skills, dates. Bad formatting causes parsing errors at this step.
- 3
Keyword & qualification matching
The ATS compares the parsed content against the job description. It looks for required skills, qualifications, job titles, and years of experience.
- 4
Scoring & ranking
The ATS assigns each application a relevance score and ranks all applicants. Most employers configure a threshold below which applications are filtered out automatically.
- 5
Recruiter review
Only the top-ranked CVs reach a human recruiter. For high-volume roles, that may mean only the top 10–20% of applications are ever read by a person.
ATS Systems Used by UK Employers
There is no single “UK ATS” — different sectors use different platforms. These are the ATS systems you are most likely to encounter when applying for jobs in the UK, along with the sectors and example employers that use each one.
| ATS Platform | Common In |
|---|---|
| Workday | Large enterprises, retail, FMCG |
| SAP SuccessFactors | Banking, retail, energy |
| Trac | NHS & wider healthcare |
| Oleeo | Civil Service, graduate schemes |
| Greenhouse | Tech, scale-ups |
| Lever | Tech, mid-market |
| Bullhorn | Recruitment agencies |
| Eploy | UK mid-market employers |
| iCIMS | Multinationals operating in UK |
| Taleo (Oracle) | Large legacy enterprises |
| Cascade | UK SMEs and councils |
| Networx | Housing associations, charities |
Smaller UK employers often rely on the ATS features built into job boards such as Indeed, Reed, Totaljobs and LinkedIn Jobs rather than running a dedicated ATS internally.
Where You Will Encounter an ATS in the UK
NHS & Healthcare
NHS Jobs runs on the Trac system. Almost every NHS Trust application is processed through it. Private healthcare employers commonly use Workday or SuccessFactors.
Civil Service & Public Sector
Civil Service Jobs uses Oleeo. Local councils typically run Networx, iTrent or Cascade. Applications often combine the ATS with structured competency questions.
FTSE 100 & Large Enterprises
Workday, SAP SuccessFactors and Oracle HCM dominate. Banking, retail, energy and FMCG hiring almost always passes through one of these.
Tech & Scale-Ups
Greenhouse and Lever are standard at UK tech employers, alongside Workable and Ashby at smaller startups.
Recruitment Agencies
Bullhorn is the most common agency ATS in the UK, followed by JobAdder and Vincere. Reed, Hays and Michael Page each operate proprietary platforms on top.
Charities & Third Sector
Networx, Eploy and CharityJob’s built-in ATS are widely used. Smaller charities often use Indeed’s ATS features.

Why UK CVs Fail ATS Systems
ATS rejection is rarely about your qualifications. It is almost always one of these fixable issues:
✕Missing keywords from the job description
If the job advert says “project management” and your CV says “managed projects,” the ATS may not register a match. Mirror the wording from the job posting.
✕Two-column layouts and tables
Most ATS parsers read top-to-bottom in a single column. Tables, text boxes, and side-by-side layouts often scramble the extracted text.
✕Headers, footers and graphics
Contact details placed inside the page header are frequently missed entirely. Logos, icons and infographic CVs are unreadable to most ATS systems.
✕Non-standard section headings
Use “Work Experience,” “Education,” and “Skills.” Creative headings like “My Journey” or “What I Bring” may not be recognised as standard sections.
✕PDFs created from images
A PDF that is actually a scanned image cannot be parsed at all. Always export your CV as a text-based PDF (or DOCX) directly from your word processor.
✕Unusual fonts and small text
Stick to common fonts (Calibri, Arial, Helvetica, Georgia) at 10pt or larger. Decorative fonts can cause character-level parsing errors.

ATS-Friendly UK CV Checklist
Run your CV through this checklist before submitting any UK job application. It covers the issues that cause the majority of ATS rejections.
- ✓Save as a text-based PDF or DOCX (not a scanned image).
- ✓Use a single-column layout — no tables, text boxes or side panels.
- ✓Use standard section headings: Personal Statement, Work Experience, Education, Skills.
- ✓Mirror keywords from the job description, especially in your work-experience bullets.
- ✓List job titles, dates and employers in a consistent format (Job Title — Employer — MM/YYYY – MM/YYYY).
- ✓Spell out acronyms at least once (e.g. “Chartered Institute of Personnel and Development (CIPD)”).
- ✓Use British English spellings to match UK job descriptions (“optimise,” “organisation”).
- ✓Include relevant UK qualifications (A-levels, GCSEs, degree classification, professional registrations).
- ✓Put contact details in the body of the CV — not in the header or footer.
- ✓Stick to common fonts: Calibri, Arial, Helvetica, Georgia, Times New Roman.
