Your CV has one job: to get you an interview. It doesn't need to tell your whole story. It doesn't need to be creative. It needs to be clear, credible, and formatted in a way that both automated screening systems and senior hiring managers can read in under 30 seconds.
In competitive technical markets — Cleantech, Cyber Security, engineering, and infrastructure — the stakes are higher. Hiring managers review dozens of applications. Recruiters scan CVs in seconds before deciding to call. ATS (Applicant Tracking Systems) score your CV before any human sees it. Structure isn't a nice-to-have. It's a filter.
This is what we've learned from our conversations with technical candidates and hiring managers across Cleantech and Cyber Security — and what genuinely makes the difference.
Why CV Structure Gets You Rejected Before You're Read
Research by Ladders (eye-tracking study, 2018) found that recruiters spend an average of 7.4 seconds on initial CV review. More recent data from LinkedIn puts this at under 10 seconds for most roles receiving high application volumes. The first pass isn't a read — it's a scan.
In that scan, a recruiter is looking for three things: your current or most recent role, the company you work for, and an overall impression of clarity and credibility. If they can't find these within seconds, they move on.
Beyond the human screen, many organisations — particularly larger ones in energy, utilities, defence, and financial services — use ATS software that parses your CV before it reaches a person. These systems rank candidates by keyword match, section detection, and format compatibility. PDFs with tables, headers in text boxes, or graphics can fail to parse entirely.
The Recommended CV Structure
For technical roles in the UK market, the structure below consistently performs best. It's logical, ATS-readable, and puts your strongest material where eyes land first.
CV Structure — Recommended Layout
1
Contact & Header
Full name · Professional title · Location (city/region, not full address) · Phone · Email · LinkedIn URL
Always first
2
Professional Summary
3–4 sentences. What you do, your specialism, years of experience, and what you're seeking. No buzzwords.
Critical
3
Core Skills / Technical Competencies
A concise keyword-rich block. Tools, technologies, methodologies, certifications. 10–16 items maximum.
ATS booster
4
Professional Experience
Reverse chronological. Each role: title, employer, dates, 3–6 bullet points focused on outcomes and scope. Quantify wherever possible.
Longest section
5
Education & Qualifications
Degree, institution, year. Include professional qualifications (CEng, CISSP, Prince2, etc.) here or directly below.
After experience
6
Professional Memberships & Certifications
IET, BCS, CIBSE, ISACA, ISC², CREST, etc. Industry body memberships signal credibility in technical markets.
Optional
Section 1: Your Header
Your name should be the largest text on the page — bold, 18–22pt. Beneath it, include a professional title (not your current job title verbatim if it doesn't reflect what you're targeting), your city or region, phone number, and a professional email address. Include your LinkedIn URL — most technical hiring managers will check it.
Do not include: Date of birth, photograph, nationality, marital status, or full home address. These are unnecessary in UK hiring, can introduce bias, and take up space your CV can't afford to waste.
Section 2: Professional Summary
This is the most underused and most important section of a technical CV. Hiring managers who scan your CV will often read this first and use it to decide whether to read further. It should be 3–4 sentences that answer: who you are professionally, what you specialise in, how much experience you have, and what you're looking for.
✗ Weak Summary
"I am a hardworking and dedicated professional with experience in the energy sector. I am passionate about renewable energy and am looking for a challenging role where I can develop my skills and contribute to the team."
✓ Strong Summary
"Electrical Design Engineer with 8 years' experience in UK utility-scale solar PV and BESS projects, from preliminary design through grid connection and energisation. Skilled in AutoCAD, PVsyst, and BS 7671 compliance. Seeking a senior design role with a developer or EPC contractor on projects of 50MW+."
The strong version tells a recruiter your discipline, your sector, your experience level, your tools, and what you want — all in four lines. The weak version says nothing a recruiter can act on.
Section 3: Core Skills Block
This section exists primarily for ATS purposes, but also helps human readers build a quick mental map of your capabilities. List skills as short phrases in a two- or three-column format. Aim for 10–16 items. Include tools, technologies, methodologies, and relevant standards or certifications.
Example: Solar O&M Engineer
The skills a hiring manager expects to see — not generic "electrical" experience
18th Edition (BS 7671)
NVQ Level 3 Electrical
Solar PV Fault Diagnosis
DC String & Module Testing
Inverter Maintenance (SMA, SolarEdge)
AC Distribution & Protection
IPAF / Working at Height
Thermographic Inspection
SCADA & Monitoring Platforms
Example: SOC Analyst
Generic "cyber security experience" tells a hiring manager nothing — these specific tools and skills do
SIEM (Splunk / Sentinel / QRadar)
Log Analysis & Correlation
Threat Detection & Triage
EDR (CrowdStrike / SentinelOne)
Incident Response & Escalation
Phishing & Email Analysis
MITRE ATT&CK Framework
Network Traffic Analysis
CompTIA Security+ / SC-200
Section 4: Professional Experience — The Make-or-Break Section
For each role, include: job title, employer name, employment dates (month and year), and a brief context line (what the organisation does, if it's not widely known) followed by bullet points.
The most common mistake in this section is describing responsibilities instead of outcomes. Responsibilities tell a recruiter what your job description said. Outcomes tell them what you actually did.
✗ Responsibility-led bullet (weak)
- Responsible for managing substation design projects
- Involved in stakeholder communication and DNO liaison
- Worked on HV cable routing and protection system design
✓ Outcome-led bullet (strong)
- Led electrical design for three 33kV substation upgrades across a 120MW solar portfolio, delivering all three within programme and under budget
- Managed grid connection process for a 50MW BESS project from G99 application to commissioning, coordinating directly with the DNO and resolving two contested protection settings
- Developed HV protection philosophy documentation adopted as the company standard across seven subsequent projects
Notice the difference: scope (120MW, 50MW), specificity (G99, 33kV), and outcome (within budget, adopted as standard). Every bullet should aim for at least one of these three elements.
ATS Compatibility: What You Might Be Getting Wrong
Many CVs are structurally strong but ATS-unfriendly. Here's what kills your score before a human sees you:
| Common Mistake |
Why It's a Problem |
Fix |
| Tables and text boxes |
ATS parsers often skip or garble content inside tables and text boxes |
Use plain paragraph formatting with clear section headings |
| Headers and footers |
Many ATS systems do not parse Word/PDF headers and footers |
Put your name and contact info in the main body, not a header element |
| Graphics and icons |
Skills bars and icons are invisible to ATS — they see blank space |
Use text-based skill lists, not graphical representations |
| Non-standard section names |
"My Journey" or "What I Bring" confuses ATS section detection |
Use standard labels: Experience, Education, Skills, Summary |
| Saving as PDF with unusual fonts |
Some PDF renderers corrupt non-standard font characters |
Use standard system fonts (Calibri, Arial, Georgia) and save as .docx where possible |
Length, Format, and Final Checks
Length: Two pages is the UK standard for technical professionals with 5+ years' experience. One page for early-career. Three pages is acceptable for very senior candidates with extensive project portfolios, but no more. Every line should earn its place.
Format: Use a clean, single-column or simple two-column layout. No photographs. No bright colours. Consistent font throughout (one typeface, two sizes maximum). Generous margins — a crowded CV signals poor judgement about what matters.
File format: Submit as PDF unless the employer specifically requests Word. PDFs preserve your formatting. Name your file: FirstName-LastName-CV.pdf — not "My CV" or "CV Final v3".

A well-structured CV doesn't just help you get interviews — it sets the tone for how hiring managers read you before you walk in the room. It signals that you understand how to communicate clearly, prioritise what matters, and present information professionally. In technical markets where credibility is everything, that impression starts before you say a word.
