Electrician — your shift
Identify, isolate, lock, prove dead — then work. And test everything before you certify it. Do the job one step at a time. Tap the thing that should happen next.

What does a electrician do?
You install and test circuits that will be hidden inside walls, and the only thing that ever stands between a fault and a fire is that you tested it properly.
Also called: electrical installer, sparks, electrical technician.
A day looks like
- 1You identify the circuit, isolate it, lock it off and then prove it dead — in that order, every time.
- 2You run cables where somebody will later drill, so you put them in the safe zones.
- 3You test everything: continuity, insulation resistance, loop impedance, RCD trip times.
- 4You fill in a certificate, and it is a legal document rather than paperwork.
Hardest part
Everything you do is invisible within a week. A bad joint behind plaster looks exactly like a good one for about two years, and then it becomes a fire — so the standard is entirely self-enforced.
Best part
A board you have built and tested, labelled properly, where every reading is well inside limits and somebody can understand it in twenty years.
How you actually become a electrician
- At schoolAn apprenticeship — this is a regulated trade and the route is well defined.
- TrainingLevel 3 electrical installation, AM2 practical assessment, then the wiring regulations and inspection and testing.
- How longFour years to qualify; competent person scheme registration after that.
- Your first jobApprentice electrician, pulling cable and watching tests.
Frequently asked questions
- Why is 'proving dead' a separate step from switching off?
- Because a switched-off breaker is not proof. Labels are wrong, circuits share paths, and testers fail. You test the conductors and then prove the tester still works, so a dead reading actually means dead.
- What is a borrowed neutral?
- A circuit whose return path goes through a different circuit. Everything works normally, but isolating one circuit leaves conductors live from the other — which is why it is one of the most dangerous legacy faults an electrician can find.
- Is electrical work regulated?
- Heavily. Notifiable work must be certified, and certification requires competence and registration. The certificate records measured test results and is signed by an individual who is accountable for them.

Plumber
You find the leak, which is almost never where the damp is, and you work out what to turn off before you touch anything.
Site Manager
You run a site where eight different trades all need the same space on the same day, and you are the person who can stop any of them.
Groundworker
You dig the holes and lay the drains everything else depends on, and the two things that can kill you are collapse and what is already buried.
Building Control Inspector
You inspect work at the stages where it can still be seen, and you are the person who fails a pour nobody wants failed.
Structural Engineer
You calculate whether a building will stand up, and you put your name on the answer.
Demolition Supervisor
You take a building down in the reverse order it went up, and the two things that decide whether anybody gets hurt are sequence and asbestos.
Fire Safety Engineer
You design how everybody gets out of a building that is on fire, and how long the building has to hold up while they do.
Retrofit Insulation Installer
You make old houses warm, and the whole skill is doing it without trapping moisture inside the wall.
Architect
You decide what a building is — how it is entered, lit, used and lived in — inside a budget, a site and a set of regulations that all say no.
Quantity Surveyor
You work out what a building will cost before it exists, and then you defend or challenge every change to that number.
Crane Operator
You move several tonnes through the air over people's heads, mostly without being able to see where it is going.
Heat Pump Engineer
You replace a boiler with something that runs at half the temperature, which means you have to redesign how every room in the house gets warm.
Glazier
You fit glass, which is heavy, sharp and unforgiving — and you decide which kind of glass the law requires in each location.
Damp & Timber Surveyor
You work out why a wall is wet, which is almost never the reason the last person said, and you are paid by people who sell the cure.
Carpenter
You set out, mark and cut timber to fit a building that is never quite square, and you only get to cut each piece once.
Bricklayer
You build walls to a line, level and plumb, at a speed that decides whether the job makes money — and the line is not a suggestion.
Scaffolder
You build the structure everybody else works from, and you build it while standing on the part you have already built.
Roofer
You keep water out of a building using overlapping pieces and gravity, working on a slope, above everything else.
Plasterer
You put a wet material on a wall and have a fixed number of minutes to make it flat, because it is setting while you work.
Steel Erector
You bolt a building's skeleton together in the air, and the frame is not stable until you have finished making it stable.
Land Surveyor
You establish where everything goes, to millimetres, and every other trade on the site builds off your marks without checking them.
