Introduction
Every year, thousands of qualified UK jobseekers wonder why their CV never gets shortlisted, even when they meet all the job requirements. The truth is, it is often not your skills or experience holding you back. It is your CV failing to pass through Applicant Tracking Systems, also known as ATS.
Over 98 percent of large UK employers now use ATS software to screen CVs before a human recruiter ever sees them. These systems scan, rank, and filter applications based on keywords, formatting, and structure. One small mistake can mean instant rejection, even for top candidates.
Many UK professionals unknowingly sabotage their job search with hidden ATS mistakes that cost them interviews, confidence, and time. From incorrect formatting and missing keywords to UK specific compliance issues, these errors quietly block opportunities.
In this guide, you will discover the most common and costly ATS mistakes UK candidates make, why they happen, how to fix them step by step, and how to optimise your CV for both machines and human recruiters. By the end, you will have a clear roadmap to improve your job success and stand out in the UK market.
What Is an ATS and Why It Matters in the UK Job Market
An Applicant Tracking System is software used by employers to manage, filter, and rank job applications. Instead of manually reviewing hundreds or thousands of CVs, recruiters rely on ATS platforms to scan applications automatically.
Why ATS Is So Important in the UK
In the UK, ATS adoption is especially high among:
- Large corporations
- NHS trusts
- Government departments
- Recruitment agencies
- Multinational employers
- Graduate scheme employers
Popular ATS platforms in the UK include:
- Taleo
- Workday
- Greenhouse
- iCIMS
- SmartRecruiters
- Bullhorn
- Jobvite
These systems filter out up to 75 percent of CVs before a human ever reads them. That means your first real interview is not with a recruiter. It is with software.
How ATS Software Works
ATS systems typically:
- Parse your CV into structured fields
- Scan for relevant keywords and phrases
- Rank your CV against job requirements
- Filter out low scoring or incompatible formats
- Send shortlisted CVs to recruiters
If your CV is not optimised for ATS, it may never reach human eyes, regardless of your qualifications.
The Real Cost of ATS Mistakes for UK Jobseekers
Hidden ATS errors do not just reduce your chances. They can:
- Extend your job search by months
- Lower your confidence and motivation
- Force you to accept lower offers
- Cause missed career growth opportunities
- Waste time applying to roles you qualify for
A 2024 UK recruitment survey found that:
- 76 percent of rejected CVs failed due to formatting or keyword issues
- 63 percent of jobseekers did not realise ATS was filtering their CV
- 58 percent of employers rely solely on ATS before reviewing candidates
In a competitive UK job market, especially in London, Manchester, Birmingham, and remote roles, ATS mistakes can be career limiting.
Using the Wrong CV Format
Why Format Matters for ATS
ATS software struggles with:
- Tables
- Text boxes
- Columns
- Graphics
- Images
- Icons
- Fancy layouts
These elements can confuse the parser, causing your CV content to be misread, skipped, or distorted.
Common UK Formatting Errors
UK candidates often:
- Use creative Canva templates
- Add profile photos
- Use two column designs
- Insert charts or progress bars
- Place content in headers or footers
While these look visually appealing to humans, ATS systems cannot reliably extract information from them.
How to Fix It
Use a simple, clean, ATS friendly format:
- Single column layout
- Standard fonts like Arial, Calibri, Times New Roman
- Font size between 10.5 and 12
- Left aligned text
- No tables or text boxes
- No images or icons
- Use standard headings like:
- Personal Profile
- Work Experience
- Education
- Skills
- Certifications
This ensures your CV is readable by both machines and recruiters.
Not Using UK Specific Keywords
Why Keywords Are the Backbone of ATS
ATS systems match your CV keywords against job descriptions. If the keywords do not align, your CV scores low, regardless of experience.
Many UK candidates fail because they:
- Use generic terms
- Copy American terminology
- Omit UK specific job language
- Use outdated industry terms
UK vs US Keyword Differences
For example:
- CV vs Resume
- National Insurance number vs Social Security number
- University vs College
- Programme vs Program
- Maths vs Math
- Apprenticeship vs Internship
- Graduate scheme vs Entry level programme
Using US terms in UK applications can lower ATS match scores.
How to Fix It
Follow this keyword strategy:
- Copy the job description into a document.
- Highlight repeated words, skills, tools, and qualifications.
- Match those keywords exactly in your CV.
- Use both technical and soft skills.
- Include variations and synonyms naturally.
Example:
Job description mentions:
- Stakeholder management
- Budget forecasting
- Risk assessment
- Compliance reporting
Your CV should include:
- Stakeholder management
- Budget forecasting
- Risk assessment
- Compliance reporting
Not alternatives like:
- Managing people
- Financial planning
- Evaluating risks
- Reporting compliance
Exact matching matters.
Using Headers and Footers for Key Information
Why This Breaks ATS Parsing
Many ATS systems cannot read text placed in headers or footers properly. If you place your:
- Name
- Phone number
- LinkedIn URL
in the header or footer, the ATS may not extract it.
Consequences
This can result in:
- Your CV being anonymous
- Recruiters unable to contact you
- Your application being rejected automatically
How to Fix It
Place all contact information in the main body of the document at the top. Use plain text, not logos or images.
Correct format:
Missing Required UK Compliance Information
UK Specific Compliance Details Matter
Some UK roles require specific legal or regulatory information, including:
- Right to work in the UK
- Disclosure and Barring Service clearance
- Security clearance
- Professional registrations
- Driving licence type
- Visa status
Failing to include this can cause ATS rejection.
Examples
For roles in:
- Healthcare, include GMC, NMC, HCPC registration
- Education, include DBS clearance
- Engineering, include chartered status if applicable
- Construction, include CSCS card
- Transport, include licence category
How to Fix It
Add a short section titled:
Legal Eligibility or Professional Compliance
Include:
- Right to work status
- Relevant licences or registrations
- Visa status if applicable
- Security clearance if required
Keep it concise and factual.
Using Non Standard Section Headings
Why Headings Matter to ATS
ATS software looks for standard headings to categorise information. If your headings are creative, the system may not recognise them.
Problematic Headings
- My Journey
- Career Highlights
- What I Do Best
- Professional Story
- Academic Background
These may confuse the system.
Recommended Headings
Use conventional, ATS friendly headings:
- Professional Summary
- Work Experience
- Employment History
- Education
- Skills
- Certifications
- Projects
- Publications
These ensure accurate parsing.
Submitting a PDF When the ATS Requires Word
Why File Type Matters
Some ATS platforms handle Word documents better than PDFs, especially older systems used by UK public sector employers.
PDFs can:
- Break parsing
- Distort formatting
- Lose keywords
- Block recruiter editing
How to Fix It
Unless the job application explicitly requests a PDF, submit your CV in:
- .docx format
Always follow application instructions. If unspecified, use Word format for maximum ATS compatibility.
Ignoring Soft Skills and Competency Keywords
Why Soft Skills Matter in UK Hiring
UK employers place strong emphasis on:
- Communication
- Teamwork
- Leadership
- Problem solving
- Time management
- Adaptability
- Stakeholder engagement
ATS systems scan for these competencies.
How to Include Them
Instead of listing:
- Good communication
- Team player
Use evidence based phrasing:
- Led cross functional teams to deliver projects within deadlines
- Communicated effectively with senior stakeholders and clients
This improves ATS match and recruiter appeal.
Hidden ATS Mistake 9: Using Graphics, Charts, and Rating Bars
Why Visual Elements Fail ATS
ATS systems cannot interpret:
- Skill bars
- Star ratings
- Graphs
- Icons
- Logos
These elements often appear as blank or unreadable.
How to Fix It
Replace visuals with plain text:
Instead of:
Skill bar showing 90 percent proficiency in Excel
Use:
Advanced Excel including pivot tables, macros, and data analysis
Leaving Gaps Unexplained
Why Gaps Matter to ATS and Recruiters
Unexplained gaps can:
- Lower your ATS score
- Trigger recruiter concern
- Reduce interview chances
UK recruiters often screen for employment continuity.
How to Fix It
Briefly explain gaps honestly:
- Career break for family responsibilities
- Further education
- Freelance or contract work
- Health recovery
- Job search period
Example:
Career break 2022 to 2023. Completed professional certifications and freelance consulting projects.
This reassures both ATS and recruiters.
Failing to Customise Your CV for Each Job
Why One Size Does Not Fit All
Using the same CV for every application drastically lowers ATS success rates. Each job has unique keywords and requirements.
How to Fix It
For every role:
- Analyse the job description.
- Identify primary skills and competencies.
- Adjust your summary, skills, and experience sections.
- Align job titles where appropriate.
- Mirror the language used in the posting.
Customisation increases your ATS match score and interview rate significantly.
Hidden ATS Mistake 12: Using Outdated Job Titles or Industry Language
Why Job Title Alignment Matters
ATS systems match your job titles against the job description. If your titles differ significantly, your CV may score lower.
Example
Your title: Business Analyst II
Job description: Senior Business Analyst
Your CV may score lower due to mismatch.
How to Fix It
Where appropriate, adjust titles to reflect market equivalents:
Business Analyst II becomes Senior Business Analyst
Ensure this remains truthful and accurate.
Hidden ATS Mistake 13: Including Irrelevant Personal Information
UK CV Standards
Unlike some countries, UK CVs should not include:
- Date of birth
- Marital status
- Religion
- Nationality unless relevant
- Photo
- Gender
- Personal identification numbers
Including this can:
- Trigger bias filters
- Reduce ATS compatibility
- Violate employer compliance standards
How to Fix It
Keep your CV professional and role focused.
Overlooking Online Application Fields
Why Online Forms Matter
Many ATS platforms use online forms alongside CV uploads. These fields often override your CV data.
Common fields include:
- Work history
- Education
- Skills
- Certifications
If these are incomplete or inconsistent with your CV, your application may be rejected.
How to Fix It
Always:
- Fill in all fields completely
- Match information exactly to your CV
- Use keywords in form fields
- Avoid copy pasting formatting
Treat the application form as part of your CV.
Not Including a Strong Professional Summary
Why the Summary Is Crucial
ATS systems often scan the top third of your CV more heavily. Your professional summary is prime keyword real estate.
How to Write an ATS Optimised Summary
Include:
- Job title
- Years of experience
- Industry
- Key skills
- Key achievements
- Career focus
Example:
Results driven Digital Marketing Manager with over 8 years of experience in UK retail and eCommerce sectors. Proven expertise in SEO, PPC, CRO, content marketing, and analytics, delivering consistent revenue growth and customer acquisition. Seeking to leverage strategic digital skills in a senior leadership role.
This combines keywords, impact, and clarity.
Using Passive Language and Weak Verbs
Why Action Verbs Matter
ATS systems and recruiters look for impact. Passive language weakens your CV.
Replace This:
- Responsible for managing
- Involved in developing
- Helped with projects
With This:
- Managed
- Developed
- Led
- Delivered
- Implemented
- Optimised
- Increased
- Reduced
- Achieved
This improves both ATS scoring and recruiter engagement.
Ignoring Achievements and Metrics
Why Metrics Matter
ATS systems and recruiters prioritise measurable results.
How to Include Metrics
Use:
- Percentages
- Revenue figures
- Cost savings
- Time reductions
- Customer growth
- Process improvements
Example:
Increased customer retention by 32 percent through targeted CRM campaigns.
This strengthens keyword relevance and credibility.
Submitting a CV with Spelling or Grammar Errors
Why Errors Hurt ATS and Recruiters
Some ATS platforms flag spelling errors as low quality signals. Recruiters may reject CVs immediately for grammar mistakes.
How to Fix It
- Use UK English spelling
- Proofread carefully
- Use tools like Grammarly
- Read your CV aloud
- Ask a professional to review it
Accuracy builds trust and professionalism.
Using Abbreviations Without Full Forms
Why Abbreviations Can Hurt
ATS systems may not recognise abbreviations unless they are explicitly programmed.
Example
ATS may not recognise:
- PMO
- CRM
- SEO
- KPI
Unless full forms are included.
How to Fix It
Include both:
Project Management Office (PMO)
Customer Relationship Management (CRM)
Search Engine Optimisation (SEO)
Key Performance Indicators (KPIs)
This improves ATS recognition and recruiter clarity.
Ignoring Industry and Sector Keywords
Why Sector Language Matters
UK industries use specific terminology. If you use generic terms, your CV may not match industry specific ATS filters.
Examples
Healthcare:
- Clinical governance
- Patient safety
- NICE guidelines
- CQC compliance
Finance:
- FCA regulation
- Risk management
- Financial reporting
- Basel III
IT:
- Cloud migration
- DevOps
- Agile delivery
- Cybersecurity
Education:
- Ofsted standards
- Curriculum development
- Safeguarding
- SEN support
Include sector specific keywords naturally.
