Section C is safe isolation. 45 minutes, three scenarios: single-phase equipment, three-phase isolator, and distribution board. The 10-step procedure must be followed cleanly with no shortcuts. Of every AM2 section, this is the one where a single missed step is an instant fail.

“Replaced three separate apps with Elec-Mate. Certs, quotes, and scheduling all in one place.”
Daniel Palmer — DP Electrical
Section C is three separate safe isolation scenarios. You demonstrate the 10-step procedure on (1) a single-phase fixed appliance, (2) a three-phase isolator, and (3) the distribution board itself. The assessor watches every step. Safe isolation is the single most-failed skill on the AM2 — get it wrong and the rest of the day is over. The procedure must be the same every time, performed cleanly without shortcuts.
Every key change in the 2026 amendment on one page. AFDDs, TN-C-S protection, new schedule columns, model forms. Pinned on your van dash.
16 certificate types, 70+ calculators, RAMS, quoting, invoicing, AI agents, and 46+ training courses — from £6.99/mo.

The Elec-Mate apprentice tier covers every AM2 section in detail — 8 modules across ~16.5 hours, 40+ pages of NET-grounded content, plus the AM2 Testing Simulator and Mock Day. Built specifically for UK NVQ Level 3 candidates preparing for the practical assessment.
The Elec-Mate AM2 Mock Day mirrors the real assessment phases with the actual NET timings. Times you on each phase and scores you against the readiness rubric — the closest practice you can get to the real day.

Elec-Mate is my go to app for business and electrical work. It's feature rich without feeling cluttered. A true all in one app for quotes, certs, calculations, RAMS, EICRs, and more. I use it every day without fail, and it makes my workflow much smoother since I'm not jumping between apps anymore. The price-to-feature ratio is excellent. Any issues I've had, the developer responds within the hour and usually fixes them the same day. 100% recommend.
I've used the app and the web based version for a while now and it's well worth the investment. If you're an apprentice or experienced Spark give it a go, you won't be disappointed.
I've been using Elec-Mate for a while now, and honestly, it's one of the best apps I've ever downloaded. Every aspect of it feels thoughtfully designed, from the clean and intuitive interface to the powerful features that make everything so easy to manage. It's clear that a lot of care and attention went into building this app, and it shows in every detail.
