Off-the-Job Training Hours — The 20% Requirement Explained

Every electrical apprentice must complete off-the-job training. Since 1 August 2025 that means a fixed number of hours set per standard (1,066 on ST0152); earlier starts keep the 20% rule. This guide explains both, what activities count, how to record your hours, and how Elec-Mate's OJT Tracker makes it effortless.

How many off-the-job training hours does an electrical apprentice need?

It depends on your start date. For apprenticeships starting from 1 August 2025 it is a fixed total set per standard — 1,066 hours for the Installation & Maintenance Electrician standard (ST0152) across the whole apprenticeship. For starts before that date the older rule applies: at least 20% of paid working hours, about 7.5 hours per week on a 37.5-hour contract.

The total is a fixed figure set by the DfE for your apprenticeship standard — it is a target to complete, not a perpetual weekly quota. The weekly figure is just a suggested pace (total ÷ working weeks); you can front-load hours. If your apprenticeship started before 1 August 2025 the older 20% / six-hours-per-week rule still applies for the whole programme.

Key Takeaways

  • 1The off-the-job rules changed on 1 August 2025. The rule that applies to you is fixed by your apprenticeship start date for the whole programme: starts from August 2025 follow a fixed total of hours set per standard; starts before that date keep the older 20% (about six hours per paid working week) rule.
  • 2Under the current rules each apprenticeship standard carries its own fixed off-the-job total. The Installation & Maintenance Electrician standard (ST0152) requires 1,066 off-the-job training hours across the whole apprenticeship. It is a target to complete, not a perpetual weekly quota — hours can be front-loaded.
  • 3Off-the-job training means learning new knowledge, skills and behaviours related to your apprenticeship — not just college. Activities that count include college days, online learning, shadowing experienced electricians, mentoring, manufacturer training, industry visits, directed study and supervised practice of new skills.
  • 4Activities that do not count include performing normal work duties you already know how to do, English and maths functional skills study, and any training not directly relevant to the apprenticeship standard.
  • 5Elec-Mate OJT Tracker automatically logs your off-the-job hours against your standard’s fixed total. It categorises activities, tracks your completion percentage in real time, collects evidence, and generates Ofsted-ready records effortlessly.

What Is Off-the-Job Training?

Off-the-job training (OTJ or OJT) is learning that happens away from your normal day-to-day work duties. It is a mandatory component of every apprenticeship in England and a condition of the apprenticeship funding your employer receives.

The purpose of off-the-job training is to ensure that apprentices receive dedicated learning time — time specifically set aside for acquiring new knowledge, skills, and behaviours relevant to the apprenticeship standard. Without this requirement, there would be a risk that apprentices simply work as cheap labour without receiving the structured training that distinguishes an apprenticeship from ordinary employment.

For electrical apprentices on the Installation & Maintenance Electrician standard (ST0152), off-the-job training encompasses everything from formal college attendance to online study, manufacturer training, supervised practice of new skills, and directed research. It is broader than most apprentices realise — and understanding what counts (and what does not) is essential for meeting the requirement without stress.

Meeting the off-the-job training requirement is also a gateway condition for the End Point Assessment. If you cannot demonstrate that you have completed sufficient off-the-job training hours, you cannot progress to the EPA and complete your apprenticeship.

The 2025 Rule Change

On 1 August 2025 the way off-the-job training is measured changed. The long-standing "20% of paid hours" model was replaced with a fixed total number of hours set for each apprenticeship standard by the Department for Education (DfE). Which rule applies to you is determined by your apprenticeship start date — and it stays fixed for the whole programme.

Started before 1 Aug 2025

The old 20% rule still applies

Off-the-job training is at least 20% of your paid working hours — roughly six hours per week on a typical contract — for the whole apprenticeship. Your provider continues to track it this way until you reach gateway.

Starts from 1 Aug 2025

A fixed total per standard

Each standard carries its own fixed off-the-job total (DfE Annex C). For the Installation & Maintenance Electrician standard (ST0152) that total is 1,066 hours across the apprenticeship. It is a target to complete, not a weekly quota.

A few details matter under the current rules. The practical training period must run for a minimum of eight months, and there is an absolute floor of 187 hours below which off-the-job training can never be evidenced for any standard. Standards that started during August to December 2025 used lower transitional figures; from 1 January 2026 the full Annex C total is mandatory for new starts. Because the total is fixed, apprentices can front-load their hours — once the full total is banked, the provider may stop recording further off-the-job time while the apprenticeship continues to gateway and the End Point Assessment.

03 · Apprentice Guide

Off-the-Job Hours by Apprenticeship Standard

For apprenticeships starting from 1 August 2025, the DfE sets a fixed minimum number of off-the-job training hours for each standard in Annex C of the apprenticeship funding rules. Below are the figures for the main electrical standards. Your college or training provider assigns you to a standard — if you are unsure which one applies, ask them.

The Old 20% Rule (Pre-August 2025 Starts)

If your apprenticeship started before 1 August 2025, the older 20% rule applies to you for the whole programme — so this section still matters for many current apprentices. Under it, at least 20% of an apprentice's paid working hours are spent on off-the-job training, calculated over the total duration of the apprenticeship rather than on a strict week-by-week basis.

What 20% means in practice: If you work a standard 37.5-hour week, 20% equals 7.5 hours per week. If your contract is 30 hours per week, 20% equals 6 hours per week. Over a 4-year apprenticeship on a 37.5-hour week (approximately 48 working weeks per year, accounting for holidays), this works out at roughly 1,440 hours across the programme.

Flexibility: The 20% is an average over the entire apprenticeship. Some weeks you may do more (for example, during block-release college weeks), and some weeks less (for example, during intensive project periods at work). As long as the overall total reaches 20% by the time you approach the gateway, you are compliant — but the expectation is that off-the-job training is spread reasonably throughout the programme rather than left to the final few months.

Who tracks it: Both you and your training provider are responsible for tracking off-the-job training hours. Your provider will review your hours at regular progress review meetings (typically every 6 to 12 weeks) and flag any shortfall. You are responsible for recording activities that happen outside of formal college sessions — online study, shadowing, manufacturer training, and directed reading.

What Counts as Off-the-Job Training

The official definition of off-the-job training is: learning which is undertaken outside of the normal day-to-day working environment and leads towards the achievement of an apprenticeship. It can be delivered at the apprentice's normal place of work (the employer premises) provided it is clearly distinct from normal work duties.

The following activities count as off-the-job training for electrical apprentices:

College or Training Provider Days

All time spent at college or with your training provider — lectures, workshops, practical sessions, tutorials, and assessments. This is the most straightforward form of OTJ training and typically accounts for one day per week.

Online Learning and Study

Studying courses, completing quizzes, using flashcards, and practising mock exams on platforms like Elec-Mate. Self-directed study of BS 7671, textbooks, and technical resources also counts. The key is that it must be learning new knowledge or skills.

Shadowing and Mentoring

Observing or being taught by experienced electricians on types of work you have not done before. Being mentored on new skills, techniques, or approaches. This counts even when it happens on the employer's premises — the test is whether you are learning something new rather than doing your usual work.

Manufacturer Training and Industry Visits

Attending manufacturer training days (for example, learning about a new consumer unit range, EV charger installation, or smart home system). Visiting trade shows, exhibitions, and industry events. These activities develop knowledge directly relevant to your role.

Practice and Skills Development

Practising new skills in a supervised environment — for example, practising safe isolation, testing techniques, or two-way switching wiring at the workshop. Using the Elec-Mate AM2 Simulator or EPA Simulator to practise assessment-related skills.

06 · Apprentice Guide

What Does Not Count as Off-the-Job Training

Understanding what does not count is equally important. The following activities are excluded from the off-the-job training calculation:

Normal Work Duties

Carrying out installation, testing, or maintenance work that you already know how to do as part of your regular job duties. Even if this work is directly relevant to the apprenticeship standard, it is on-the-job training, not off-the-job. The distinction is whether you are learning something new or practising something you already know.

English and Maths Study

Time spent studying for Level 2 Functional Skills in English and maths does not count towards the off-the-job training requirement. These are separate requirements under the apprenticeship funding rules and are tracked independently.

Training Not Relevant to the Standard

Training that is not directly relevant to the apprenticeship standard — for example, general company induction, non-technical training, or training for activities outside the scope of the ST0152 standard — does not count.

Progress Reviews

Regular progress review meetings with your training provider or employer — while valuable — are typically not counted as off-the-job training unless they include structured learning content.

The grey area between "learning something new" and "doing your normal work" can sometimes be confusing. A good rule of thumb: if you could not do this task before your apprenticeship started (or before this training session), and it is relevant to the apprenticeship standard, then it counts. If you are repeating a task you already know how to do, it does not count — even if you are getting better at it through repetition.

How to Calculate Your Hours

For apprenticeships starting from 1 August 2025, working out your off-the-job requirement is simpler than it used to be — you read it off your standard rather than calculating a percentage.

Step 1 — Confirm your start date: Off-the-job rules follow your start date for the whole programme. If you started before 1 August 2025, use the older 20% rule (about 7.5 hours per week on a 37.5-hour contract). If you started from August 2025, use the fixed-hours method below.

Step 2 — Find your standard's fixed total: Each standard has its own off-the-job total set by the DfE. On the Installation & Maintenance Electrician standard (ST0152) it is 1,066 hours for the whole apprenticeship; on the Domestic Electrician standard (ST1017) it is 626 hours. Your provider can confirm which standard you are on.

Step 3 — Set a weekly pace: Divide your total by the number of working weeks in your programme to get a comfortable pace. For example, 1,066 hours over a 4-year programme with roughly 48 working weeks per year (about 192 working weeks) is around 5.5 hours per week — but you can front-load this and bank it early.

What you record: Your college or training-provider days usually make up a large share of the total and are logged centrally by the provider. Your job is to capture everything else — online study, shadowing on new work, manufacturer training, toolbox talks that teach something new, and directed practice — so your full total is evidenced.

Don't lose track: Because it is a single total to reach, the danger is quietly drifting behind without realising it. A couple of study sessions on Elec-Mate, a toolbox talk, or an hour of directed reading each week adds up quickly — and the tracker keeps a running tally so you always know how many hours remain.

Recording and Evidencing Your Hours

Recording off-the-job training hours is not just about keeping a total — it is about providing evidence that the training happened, what it covered, and how it relates to the apprenticeship standard. This evidence is reviewed by your training provider at progress reviews, checked at the gateway stage before the EPA, and may be inspected by Ofsted.

What to record for each activity: Date and time of the activity. Duration (how many hours). Description of what you did. What new knowledge, skills, or behaviours you gained. How the activity links to the apprenticeship standard criteria. Any evidence (certificates, screenshots, notes, photographs).

Traditional methods: Many apprentices use a paper log or spreadsheet provided by their training provider. These work but are tedious to maintain, easy to fall behind on, and difficult to verify. If you lose the log or forget to update it for several weeks, reconstructing your hours from memory produces unreliable records.

Digital tracking with Elec-Mate: Elec-Mate's OJT Tracker eliminates the tedium of manual recording. On-platform activities (courses, quizzes, flashcards, mock exams, EPA Simulator sessions) are logged automatically with timestamps and descriptions. Off-platform activities (college days, site-based training, manufacturer events) can be added manually with a few taps. Each entry is categorised by activity type and can be tagged to apprenticeship standard criteria. The tracker calculates your running total, weekly average, completion percentage against your standard's fixed total, and projects when you will reach 100% at your current pace.

Evidence collection: Beyond the hours log, Elec-Mate allows you to attach evidence to each entry — a photograph from a training session, a certificate from a manufacturer course, a screenshot of a completed quiz, or a note from a mentoring session. This evidence strengthens your OTJ record and links naturally to your apprentice portfolio.

Ofsted and Off-the-Job Training Records

Ofsted inspects apprenticeship training providers and pays specific attention to off-the-job training. During an inspection, Ofsted may review individual apprentice OTJ records, interview apprentices about their training experience, and assess whether the training provider is ensuring that apprentices receive their required off-the-job training time.

What Ofsted looks for: Evidence that off-the-job training is planned, delivered, and documented. That the training is meaningful and directly relevant to the apprenticeship standard — not just box-ticking. That apprentices can articulate what they have learned through their off-the-job training. That employers are providing the required time. That the training provider monitors OTJ compliance and intervenes when apprentices fall behind.

Why it matters to you: If your training provider receives a poor Ofsted rating partly due to inadequate off-the-job training records, it reflects on the quality of your apprenticeship. Employers and future assessors may question the robustness of your training. Conversely, well-documented OTJ records support your credibility and demonstrate your commitment to professional development.

Ofsted-ready records: Elec-Mate OJT Tracker generates records that meet the standard Ofsted expects: detailed activity descriptions, links to apprenticeship standard criteria, timestamps, evidence attachments, and compliance tracking. If your training provider or Ofsted asks to see your OTJ evidence, you can produce a comprehensive, organised record in seconds rather than scrambling through incomplete spreadsheets.

Employer Responsibilities

Your employer has specific responsibilities regarding off-the-job training. These are not optional — they are conditions of the apprenticeship funding agreement that your employer signed.

Providing time: Your employer must release you for the off-the-job training your apprenticeship requires, within paid working hours. This includes releasing you for college or training provider sessions, allowing time for directed study, and supporting learning activities on the employer premises.

Paying for training time: All off-the-job training time must be paid at your normal hourly rate. Your employer cannot deduct pay for college days or study time that forms part of the off-the-job requirement.

Supporting learning on site: Good employers go beyond the minimum requirement. They expose apprentices to a variety of work types, pair them with experienced electricians for mentoring, encourage attendance at manufacturer training events, and create a learning culture where asking questions and seeking feedback is normal and encouraged.

Monitoring and review: Your employer should participate in regular progress reviews with the training provider, discussing your off-the-job training hours, the quality of your learning, and any barriers to meeting the off-the-job requirement. If work pressures are preventing you from getting enough OTJ time, your employer and training provider should agree a plan to address this.

If your employer is not meeting their obligations: Talk to your training provider first. They have a contractual relationship with your employer and a responsibility to ensure the apprenticeship agreement is being followed. If the training provider cannot resolve the issue, contact the ESFA apprenticeship helpline or the National Apprenticeship Service for advice. Document specific instances where OTJ time was denied or pay was deducted for training days.

Tracking Hours with Elec-Mate OJT Tracker

Elec-Mate's OJT Tracker was purpose-built for electrical apprentices. It takes the hassle out of off-the-job training hour tracking and ensures you always know where you stand against your standard's fixed total.

Automatic logging: Every minute you spend studying on Elec-Mate — courses, quizzes, flashcards, mock exams, BS 7671 run-through, EPA Simulator, AM2 Simulator — is automatically logged as off-the-job training time. No manual entry needed for on-platform activities.

Manual entries for off-platform activities: Add college days, toolbox talks, manufacturer training, shadowing sessions, industry visits, and directed study with a few taps. Each entry captures the date, duration, description, and activity category.

Activity categories: The tracker organises your hours into categories: college/training provider, online learning, practical skills practice, shadowing/mentoring, manufacturer training, industry events, directed study, and other. This categorisation provides a clear picture of the breadth of your off-the-job training experience.

Compliance dashboard: See your total hours, percentage against your standard's fixed total, weekly average, and projected completion date at a glance. A traffic-light indicator shows green (on track), amber (slightly behind), or red (significantly behind). Weekly notifications remind you to log any unrecorded off-platform activities.

Evidence attachments: Attach photographs, certificates, screenshots, or notes to any entry. This evidence feeds into your portfolio and creates Ofsted-ready documentation.

Integration with other Elec-Mate features: OJT hours from the tracker are automatically reflected in your portfolio, linked to the relevant apprenticeship standard criteria, and included in the gateway readiness dashboard. When your employer and training provider review your progress, everything is in one place.

How to Work Out Your Off-the-Job Training Hours

Use these steps to find your off-the-job training requirement — fixed hours for starts from August 2025, or the older 20% rule for earlier starts.

1

Confirm your start date

Off-the-job rules follow your apprenticeship start date for the whole programme. If you started on or after 1 August 2025 the fixed-hours rule applies. If you started before that date, the older 20% (about six hours per paid working week) rule applies throughout.

2

Identify your apprenticeship standard

Your college or training provider assigns you to a standard. Most electrical apprentices are on the Installation & Maintenance Electrician standard (ST0152). Each standard carries its own fixed off-the-job total set by the DfE in Annex C of the funding rules.

3

Read off your total off-the-job hours

For starts from August 2025 the Installation & Maintenance Electrician standard (ST0152) requires 1,066 off-the-job training hours across the whole apprenticeship. Domestic Electrician (ST1017) requires 626 hours. This is a total to complete, not a weekly percentage.

4

Set a comfortable weekly pace

Divide the total by the number of working weeks in your programme to get a suggested weekly pace. The hours can be front-loaded; once you have banked the full total your provider may stop recording further hours while the apprenticeship runs on to gateway and End Point Assessment.
