A site diary is a daily written record of your activities, observations, and learning on site. For electrical apprentices, it serves as a personal log of your professional development — a running account of what you did each day, what skills you practised, what you learned, and any health and safety observations you made.
Think of it as a professional habit that working electricians use throughout their careers. On large commercial or industrial projects, site diaries are contractual documents that record progress, delays, instructions, and safety incidents. As an apprentice, your site diary is simpler — but no less valuable. It is the foundation of your apprentice portfolio and a powerful tool for tracking your growth over the four years of your apprenticeship.
The best apprentices treat the site diary as a non-negotiable daily habit — 5 to 10 minutes at the end of each working day to capture what happened while it is fresh in your mind. Over four years, these entries build an extraordinary record of your journey from day one to qualified electrician.
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.
A site diary is not just a record — it is a tool that actively supports your apprenticeship in several ways:
A good daily site diary entry covers the following areas. You do not need to write a lot under each heading — a sentence or two is usually enough.
The basics: today's date, which site you were on, and the weather conditions (this matters for outdoor work, cable pulling, and roof access decisions).
What did you actually do today? Be specific: "Ran 2.5mm twin and earth from CU to kitchen ring circuit, clipped to joists at 300mm centres" is far better than "wiring." Include quantities, locations, and methods.
Did you learn something new today? Practise a skill for the first time? Get shown a technique you had not used before? Record it — this is your most valuable evidence for both OJT hours and your portfolio.
PPE worn, risk assessments reviewed, safe isolation performed, toolbox talks attended, hazards spotted and reported, working at height precautions. Even a brief note demonstrates your H&S awareness.
What went well? What would you do differently? What questions do you need to ask tomorrow? Reflective notes show professional maturity and help you identify areas to focus on in your studies.
One of the most important things to capture in your site diary is when you practise a skill for the first time or develop a skill further. These entries directly support your apprenticeship portfolio by providing evidence of practical competence.
When recording skills, include:
Over four years, these skill entries form a comprehensive record of your practical development. When you reach the gateway stage before the EPA, having detailed records of every skill you have practised makes portfolio compilation straightforward rather than stressful.
Recording health and safety observations in your site diary is one of the most effective ways to demonstrate the professional behaviours required by the apprenticeship standard. EPA assessors specifically look for evidence that apprentices understand and apply health and safety practices.
Record the PPE you wore and why: "Safety boots, hard hat, hi-vis vest, and safety glasses for drilling into masonry." Note any site inductions, permit-to-work systems, and access control procedures.
Document any hazards you identified and how they were managed: "Noticed exposed cable damage on extension lead in communal area — reported to site supervisor and lead was removed from service." Near-miss reports show exactly the kind of awareness assessors want to see.
Every time you carry out or observe a safe isolation procedure, record it: "Performed safe isolation on ring circuit 3 using Martindale VI-13800 proving unit — proved dead, locked off with personal padlock, caution notice posted."
These entries are gold dust for your portfolio. They demonstrate that you take health and safety seriously, can identify hazards, and follow correct procedures — all of which are assessed during the EPA.

Your apprentice portfolio needs evidence mapped against the apprenticeship standard criteria. Many apprentices struggle with this because they try to compile everything in the months before the gateway. A daily site diary solves this problem by generating portfolio evidence naturally as you work.
How it works: Each site diary entry describes tasks, skills, and learning. These descriptions map directly to apprenticeship standard criteria. For example:
On Elec-Mate, site diary entries can be tagged to specific portfolio criteria. The portfolio builder then pulls in relevant diary entries automatically, so your portfolio grows as you work rather than being a separate, stressful exercise.
Elec-Mate site diary entries link directly to your portfolio criteria. Tag each entry, attach photos…
Try it free for 7 daysThe difference between a useful site diary entry and a useless one comes down to specificity. Compare these examples:
"Did wiring all day. Fitted some sockets. Wore PPE."
This tells you nothing useful. What wiring? What type of sockets? Where? Was it new learning or routine work? What PPE? This entry cannot support your portfolio or OJT records.
"First fix in Plot 12 kitchen. Ran 2.5mm T+E from CU to 6 double socket positions, clipped to joists at 300mm centres. First time using SWA gland kit for outdoor socket feed — supervised by Dave. Wore safety boots, hard hat, safety glasses for drilling. Site toolbox talk on ladder safety at 8am."
Specific tasks, a first-time skill, supervision noted, PPE detailed, and H&S activity recorded. This entry supports multiple portfolio criteria.
You do not need to write a novel. Three or four specific sentences beat three paragraphs of vague waffle. The structured prompts in Elec-Mate's site diary guide you through each section so you naturally write better, more useful entries.
Elec-Mate's site diary feature was designed specifically for electrical apprentices. It makes daily recording quick, structured, and directly connected to your portfolio and OJT tracker.
The diary prompts you through each section: tasks performed, skills practised, tools used, health and safety observations, and reflections. No staring at a blank page wondering what to write.
Snap a photo of the work you did today and attach it to your entry. Visual evidence strengthens your portfolio and makes your diary entries far more compelling.
Tag each entry to apprenticeship standard criteria. Your portfolio builder automatically pulls in relevant diary entries, so evidence accumulates naturally over your four years.
When your diary entry includes new learning or first-time skills, it can be linked to your OJT tracker as evidence of off-the-job training activities.
Elec-Mate site diary gives you structured daily prompts, photo attachments, portfolio linking, and OJT integration.

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.
