C&G 2365 · 18th Edition 2382-26 · BS 7671 A4:2026
Learn the electrical trade the way you learn a language.
Ten minutes of short lessons a day, wiring and testing rigs you work rather than read, and timed papers when the exam gets close.

You have switched off and locked off the circuit you are about to work on. What do you do next?
Two ways in
Two people use this app for two different reasons. Take the door that is yours.
Apprentices & exam candidates
I have an exam to pass
Mapped to the City & Guilds 2365 Level 2 Diploma in Electrical Installations and to C&G 2382-26. Drill the units you are weakest on, then sit a timed paper and read the breakdown by area — regs navigation, protection and selection, Amendment 4.
DIY upskillers & career-changers
I want to do the job at home properly
Start where the trade starts: proving a circuit dead, reading a board, and knowing which jobs stop being yours to do. No exam required, and the first 3 sections are free.
Doing it yourself? Read this first
Some electrical work in your own home is notifiable under Part P of the Building Regulations — a new circuit, a consumer-unit change, or work in a room with a bath or shower — and you cannot certify it yourself. There are two lawful routes and only two: an electrician registered with a competent-person scheme certifies and notifies it, or you tell your local authority building control before you start and pay for the inspection. Part P covers England and Wales, and Wales notifies more kinds of work than England does; Scotland and Northern Ireland run their own building standards. Every job, notifiable or not, still has to meet BS 7671. We teach you how the work is done and why — finishing a lesson is not a certificate, and it does not make you a competent person under any scheme.

…and 2 more sections after this one. See what they cover
7 rigs you work, not diagrams you look at
Each is the same component a lesson mounts — keyboard-operable and readable without colour vision.
Safe isolation
Walk the prove–isolate–lock off–prove routine step by step.
Consumer unit
Wire a board: devices, line, neutral and protective conductor.
Ring final testing
Take the r1, rn, r2 readings and read what they tell you.
Multi-function tester
Set the instrument up and take a reading without guessing.
Earthing and bonding
Read the intake, then bond what actually brings a potential in.
Fault finding
Probes on the circuit, readings taken, then name the fault.
EICR coding
Classify what the inspection found, and say why it codes that way.
How it works
Every question is written by us and tagged to its BS 7671 amendment — currently BS 7671:2018+A4:2026 — and superseded ones are retired rather than left to go stale.

Say what you are here for
An exam, or a job in your own house. The path leads with what you came for.

Learn in short lessons
A handful of questions, not a chapter — multiple choice, ordering, matching, fill-the-blank, scenarios.

Practise on the rigs
Wire a board, take a reading, walk the isolation routine. 7 interactive rigs, no van required.

Review before you forget
Every answer is scheduled by FSRS-6 and comes back the day before it would have slipped away.

Free practice →
Cable Sizing
Cable sizing means proving a conductor can carry its design current, survive its installation conditions and still deliver acceptable voltage at the far end.
Preview questions →
Earthing & Bonding
Earthing gives fault current a path home so protection can trip; bonding keeps the metalwork you can touch at the same potential.
Preview questions →
Inspection & Testing
Inspection and testing proves an installation is safe before it's energised — dead tests first, live tests after, results certified in writing.
