Year 1 covers the foundations that everything else is built upon. The topics covered at college and on site include the following.
Basic installation skills: Cable preparation (stripping outer sheath, stripping conductor insulation, preparing cable ends for termination). Cable termination (connecting conductors to terminals in accessories, consumer units, and junction boxes). Cable routing and clipping. Containment installation (trunking, conduit, cable tray). Fitting back boxes, socket outlets, light switches, and other accessories. These hands-on skills are the bread and butter of electrical installation — you will practise them hundreds of times over the apprenticeship.
Health and safety: Site safety fundamentals. The Health and Safety at Work Act 1974 and your responsibilities under it. Risk assessment — identifying hazards and controlling risks. Personal protective equipment (PPE) — what to wear and when. Manual handling — lifting and carrying safely. Working at height — safe use of step ladders and platforms. COSHH (Control of Substances Hazardous to Health) — recognising and handling hazardous substances. Safe isolation — the prove-test-prove procedure for confirming circuits are dead before working on them.
Hand tools: Correct use of electricians' screwdrivers, side cutters, long-nose pliers, cable strippers, saws, files, drills, and measuring tools. Tool maintenance and care. Tool safety — using VDE insulated tools when working near electrical equipment.
Cable types and sizes: Twin-and-earth cable (flat profile cables for domestic wiring). Flexible cables. Armoured cables. Single-core cables. Cable sizing basics — why different circuits use different cable sizes. Cable identification — recognising cable types by their construction and markings.
Basic testing concepts: Introduction to test instruments — what a multifunction tester does. Continuity testing — checking that conductors are connected end to end. Insulation resistance testing — checking that insulation between conductors is intact. Polarity — confirming that line and neutral are correctly connected. You will not be carrying out independent testing in year 1, but you will observe and assist with testing procedures. BS 7671 Part 6, Regulation 643.1 prescribes a mandatory sequence: the tests of Regulations 643.2 to 643.6 (covering continuity, insulation resistance, polarity, earth electrode resistance, and earth fault loop impedance) shall be carried out in that order before the installation is energised. Learning this sequence early — and understanding why it is done before power is applied — is one of the most important foundations of safe electrical work. Earth fault loop impedance (Zs and Ze values) is one of the key concepts you will encounter when this testing is explained on site and at college.
Introduction to BS 7671: The structure of the Wiring Regulations. Key concepts — protection against electric shock, overcurrent protection, earthing. You will not need to know BS 7671 in depth in year 1, but you begin building familiarity with the document that governs every aspect of electrical installation work. One A4:2026 change you will see on every domestic job from the start: BS 7671 Regulation 411.3.4 now requires that all AC final circuits supplying luminaires in domestic premises shall be protected by an RCD with a rated residual operating current not exceeding 30 mA — so lighting circuits must have 30 mA RCD protection, not just ring finals and socket circuits.
