What is CPD for electricians?
Continuing Professional Development is the record you keep of how you stay current. For electricians it is less about collecting certificates and more about being able to show, on demand, that your knowledge has moved with the regulations.
How many CPD hours do UK electricians need per year?
The number most electricians have heard is 30 hours a year. It is a scheme benchmark rather than a legal minimum, and understanding the difference saves a lot of anxiety before an assessment.
EICR explained: what landlords need to know
Since 2020, private landlords in England have had to hold a satisfactory Electrical Installation Condition Report and give tenants a copy. Most disputes we see come from misunderstanding the codes rather than the duty itself.
BS 7671 Amendment 4:2026 — what changed and what it means on site
Amendment 4 — the Orange Book — was published on 15 April 2026. The Brown Book stays valid until 15 October 2026, so you have a short window to get current before the changeover.
How to choose an accredited electrical training provider
Electrical training is a crowded market and the marketing rarely tells you what matters. These are the checks that separate a qualification employers recognise from a certificate of attendance.
The complete UK EICR guide: observation codes, landlord rules and 2026 compliance
An Electrical Installation Condition Report is the periodic health check on a fixed installation. This guide covers what is inspected, how observations are coded, how often each type of property needs one, and what a landlord must do when a report comes back unsatisfactory.
The BS 7671 testing sequence: dead tests, live tests and the order that matters
The testing sequence is not a formality. Each test assumes the previous one passed, so running them out of order can leave you energising a circuit with a fault you have not yet found.
UK earthing systems explained: TN-S, TN-C-S, TT and what Ze should read
Identifying the earthing arrangement is the first thing you do at the intake and the thing most likely to be recorded wrongly. Get it wrong and every Zs limit, bonding decision and EV charger design that follows is wrong too.
Safe isolation: the full procedure, step by step
Almost every electrical fatality at work involves someone who believed a circuit was dead. Safe isolation is the one procedure where shortcuts are never defensible, and it is the first thing an assessor watches you do.
Ring final circuit testing explained
The ring final test is the one most often skipped, fudged or misunderstood. Done properly it proves the ring is genuinely continuous and finds broken legs and interconnections that no other test will reveal.
Consumer unit replacement: the pre-work checklist
A board change looks like a two-hour job until you open the old one. The work that determines whether it goes well happens before you quote, not on the day.
C2 or C3? Making consistent EICR coding decisions
Two competent inspectors can look at the same installation and produce different reports. The gap is almost always at the C2 and C3 boundary, and it is the difference between a satisfactory report and a landlord facing 28 days of remedial work.
Fast-track electrician courses: qualified in 18–24 months without an apprenticeship
You do not need four years on apprentice wages to become an electrician. You do need the right qualifications in the right order — and to avoid short courses that promise a career they cannot deliver.
The new Level 3 electrotechnical qualification (C&G 5357) explained
The on-site competence qualification that leads to the Gold Card is changing. Here is what the move from 2357 to 5357 means if you are mid-way through training.
News: Workplace Charging Scheme opens to schools and colleges — what it means for installers
Government grant funding for workplace charge points now extends to state-funded education sites — a sizeable new market for commercial EV installers.
