Structured credentials in unstructured text: parsing CVs for the trades

TL;DR

  • Trade CVs are dense with high-signal structured tokens (18th Edition, BS 7671, AM2, ECS, NVQ Level 3) that a naive keyword matcher finds trivially and then overweights.
  • The hard problem is the opposite direction: the qualification is easy to extract, the evidence of applying it is buried in free text or absent entirely.
  • Scoring credential presence without evidence of use produces false positives at the top of the pipeline and rejects genuinely experienced candidates further down.

Building CVPilot's keyword extraction meant handling sectors well outside the tech CVs everyone benchmarks against. The trades turned out to be the interesting case. An electrician's CV contains a cluster of standardised credential tokens that any regex will find, alongside a description of a decade of work that frequently contains no extractable evidence at all.

That asymmetry is a scoring problem, and it is one that penalises the candidate rather than the parser.


You have got the 18th Edition, the ECS Gold Card, and twenty years on the tools across domestic, commercial, and industrial sites. So why does the application vanish the moment you hit submit? The honest answer is that a piece of software read your CV before a human ever did, and it was not impressed by your card alone.

High-volume trades hiring runs through an Applicant Tracking System, the same as any office job. When an agency posts one maintenance role and gets 180 applications by Friday, nobody reads all 180. The ATS ranks them by keyword match first, and the recruiter opens the top handful.

This guide is written for the person holding the card, not the person selling the software. We will cover the exact qualifications, compliance terms, and sector vocabulary the filters search for, how to quantify work that lives on a site rather than a spreadsheet, and the one habit that costs time-served sparks the interview they had already earned.


Why a trades CV gets screened at all

There is a myth on site that CVs are for office workers and that a good spark gets work through the phone and the reputation. That still holds for a lot of direct hires. The problem is that agency and framework applications almost never reach a human cold.

Agencies use a database. When a contract manager needs three approved electricians for a data centre fit-out on Monday, the consultant types the requirements into the system and pulls matching profiles. If your CV never used the phrase "approved electrician" or "three-phase", you are not in the results, and your reputation cannot save a record the software never surfaced.

Direct employer applications differ slightly. A facilities manager or an M&E contractor may read more carefully, but the large ones still use ATS software to sift the first wave. Either way, the machine is the first gate and keywords are the key.

Key Takeaway: Your trade reputation opens doors in person, but on agency and framework applications a database decides who gets seen first, and it only understands the words on the page.


The contrarian bit: your card is not the evidence

Here is the mistake I see on almost every electrician CV that lands in my inbox. The candidate lists the 18th Edition, the 2391, the NVQ Level 3, the AM2, the ECS card, and then more or less stops. The thinking is reasonable: the qualifications should speak for themselves.

They do not. The ATS finds the card, ticks the box, and then goes looking for evidence that you did the work. When the bullets underneath say "carried out various electrical duties" and nothing more, there is nothing to match against the job spec, and your file scores low.

So a fully time-served electrician with a Gold Card loses to someone less experienced who simply wrote better bullets. The card gets you past the qualification filter. The described work is what actually ranks you, and that is the half most people skip.

Key Takeaway: List the card, then prove it. Qualifications clear the first filter; quantified, keyword-rich bullets are what push you to the top of the recruiter's list.


Qualifications and cards the ATS searches for

Recruiters paste specific terms into the search box, and they use both the formal name and the shorthand. Your CV should carry both so it matches either query. Write "18th Edition (BS 7671)" in full at least once, because some systems search the standard number and some search the plain-English name.

The essential set for most UK electrical roles includes the 18th Edition (BS 7671), City & Guilds 2365 and 2357, the 2391 for inspection and testing, the 2392 for initial verification, NVQ Level 3, the AM2, and your ECS card with its JIB grading. If you hold Approved Electrician status or a Gold Card, name it explicitly rather than leaving the reader to infer your grade from the card colour.

Do not bury these in a paragraph. A clear "Qualifications" heading with each item on its own line reads cleanly for a human and parses reliably for the software. A CV built on a proper complete ATS-friendly CV guide structure gives every card its own parseable line.

Key Takeaway: Spell out both the standard number and the common name for each qualification, and give the card its exact grade so the search matches you either way.


Compliance, testing, and sector vocabulary

Compliance language is where trades CVs win or lose against the job spec, because these are the exact phrases a facilities or M&E advert repeats. If the role is inspection and testing, the words EICR, periodic inspection and testing, and initial verification need to appear in your work history, not just your skills list.

Testing and certification terms worth carrying, where true, include EICR, minor works certificate, Part P, RAMS, permit to work, LOLER, PAT testing, and the scheme names NICEIC and NAPIT plus SafeContractor. Never claim a scheme registration you do not hold; recruiters verify these fast.

Sector vocabulary tells the system which environment you know. Containment, tray and basket, SWA, three-phase, distribution boards, and fault finding signal commercial and industrial competence. BMS, HV/LV, and PLC signal maintenance and controls, while solar PV, EV charge point installation (OZEV), and heat pumps signal the renewables work now driving a large share of new UK vacancies.

Key Takeaway: Match the advert's compliance and sector words inside your actual experience, and only ever claim schemes and registrations you genuinely hold.


Keywords by role level

Not every term belongs on every CV. The words that get an improver shortlisted differ from the words a supervisor needs. Use the table to pick the language that matches the level you are applying for, and lift the exact phrasing from the advert wherever it fits your real experience.

Role level Keywords the ATS searches for
Apprentice / Improver City & Guilds 2365, NVQ Level 3 (working towards), ECS labourer/apprentice card, first fix, second fix, containment, cable pulling, under supervision
Electrician (domestic) 18th Edition, Part P, consumer unit upgrades, minor works certificate, EICR, fault finding, rewires, NICEIC/NAPIT
Electrician (commercial / industrial) Three-phase, distribution boards, SWA, tray and basket, containment, HV/LV, motor control, RAMS, permit to work
Maintenance electrician Reactive and planned maintenance, PPM, fault finding, BMS, PLC, PAT testing, LOLER, downtime reduction, first-time fix
Approved Electrician 2391 inspection and testing, initial verification, EICR, AM2, JIB Approved grading, Gold Card, sign-off authority
Supervisor / Project Manager Team of X electricians, RAMS authoring, site management, CSCS, apprentice supervision, contract value, zero-RIDDOR record, programme delivery

Key Takeaway: Target the keyword set for the exact level you want, not a generic pile of every term, and mirror the advert's wording where it is honestly true of you.


How to quantify work that lives on a site

Office workers quantify with revenue and budgets. Trades work has numbers too, they just sit in different places, and a number in a bullet beats an adjective every time. The value of the contracts you worked, the count of EICRs you completed, your first-time fix rate, the downtime you cut, the sites you ran, and the apprentices you supervised are all measurable.

Compare the two versions of the same real work below. The left column is what most electricians write. The right column is the same job described so the ATS and the recruiter can both see the scale.

Before (vague) After (quantified)
Carried out testing on various sites Completed 340+ EICRs across 22 commercial sites, achieving a 100% on-time certification record
Did fault finding and repairs Raised first-time fix rate from 71% to 89% on a 40,000 sq ft manufacturing site, cutting production downtime by 30%
Worked on a big install project Delivered second fix and containment on a £2.4m office fit-out, wiring 18 distribution boards to programme
Supervised some apprentices Supervised 4 apprentices and a 6-strong install team, maintaining a zero-RIDDOR record across an 18-month contract
Responsible for maintenance Managed PPM schedule for 3 industrial units, reducing reactive callouts by 25% year on year

Notice that the right-hand versions carry keywords and numbers together. "EICRs", "containment", "distribution boards", and "PPM" match the search, while the figures give the recruiter a reason to call. The number is what turns a keyword match into an interview.

Key Takeaway: Every bullet should pair a searchable term with a real figure, whether that is contracts values, EICR counts, fix rates, or the size of the team you led.


Progression keywords from apprentice to project manager

Your CV should signal where you are on the ladder, because recruiters filter by seniority as well as trade. An apprentice CV leading with "sign-off authority" looks wrong, and a supervisor CV that only mentions cable pulling undersells the level you have actually reached.

The natural progression reads apprentice, improver, electrician, approved electrician, then supervisor or project manager. Each rung has its own vocabulary: improvers add "working towards NVQ Level 3", approved electricians add "2391 inspection and testing" and "sign-off authority", and managers add "RAMS authoring", "programme delivery", and "contract value".

If you are mid-jump, name the target level in your profile summary while your history proves you are ready. Writing "approved electrician with inspection and testing sign-off" at the top tells both the software and the reader exactly which shortlist you belong on. A tool like CVPilot flags which of these level-specific terms your draft is missing before you send it.

Key Takeaway: Match your keywords to the rung you are aiming for, and state the target level in your summary so the filter sorts you into the right band.


Putting it together

Start with a tight profile summary naming your grade, your key qualifications, and your sector. Follow with a clean qualifications block, then a work history where every role carries compliance terms and quantified bullets. Keywords earn the read, numbers earn the call.

Before you apply, read the advert twice and note the exact phrases it repeats, then make sure those honest matches appear in your experience. Run the finished CV through CVPilot to see your ATS score and the specific electrical terms you are missing, then fix the gaps and send it with confidence.

Key Takeaway: A trades CV that pairs the right card language with real numbers, tuned to each advert, beats a more experienced spark who let the qualifications speak for themselves.
