Just curious
Could this work suit me?
Have a go on the rigs, then read how people actually get into the trade. We help you explore. We don’t qualify anyone.
Already training
On a course or an apprenticeship?
Use the lessons, topic pages and practice papers alongside your college work. Short sessions, on your phone, whenever suits.
At home
Want to understand your own home?
Understand safety concepts, what’s inside a fuse board, and why practical work needs appropriate training and professional judgement. The first 3 parts 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.
A small taste of the learning
Start with a question. Explore a rig. Build your understanding one short sitting at a time.
Community draft — not yet reviewedWhat this means
This question has not yet been reviewed by a qualified electrician. It is a community draft: check anything you plan to act on against BS 7671 and your own supervisor before you rely on it. Completing it does not make you competent, certified or registered.
You have switched off and locked off the circuit you are about to work on. What do you do next?
Your next step
A path, not a pile of questions
Start with the basics, meet an idea, practise it and revisit what needs another go. The first 3 parts are free.

Safe Isolation Procedure
Safe isolation is the habit that keeps you alive before you touch a circuit: switch it off, lock it off, then prove it is dead.

Earthing & Bonding
Earthing gives a fault a safe path home so the protection trips.

UK Cable Colours
Brown is line, blue is neutral, green-and-yellow is earth — but older installations still carry red and black, and three-phase adds grey to the mix.
Read and try →
Ohm's Law
Ohm's law — voltage equals current times resistance — is the one equation every electrical calculation eventually stands on.
Read and try →
RCD Types
An RCD is a safety switch that trips when current leaks out of a circuit.
Read and preview →
Consumer Units
The consumer unit — the fuse board — is where a home's supply splits into circuits, each with its own protection.
