The C&G 2365 Level 2 Electrical Installation Diploma is often used as an entry-level module for aspiring electricians. This course provides a robust introduction into electrical theory, and lays the foundations for practical skills to be developed. From this base, candidates will usually go onto conduct the Level 3 equivalent qualification, before seeking to acquire their NVQ and AM2 at the conclusion of their initial learning journey.

For reference, the initials ‘C&G’ refer to the City and Guilds. This organisation is an industry-recognised leader in training provision, and therefore carries a strong reputation across the sector. The City and Guilds also offer courses in a number of other trades and commercial pursuits. Prospective candidates can undertake qualifications with other skills providers, such as the EAL. However, this article will refer exclusively to the C&G programme, as this is the most readily used throughout the electrotechnical industry.

The qualification is generally undertaken by individuals who can be categorised into two groups. These are apprentices, and those participating in ‘front-loaded’ training plans.

Apprentice electricians

Those on apprenticeship schemes will cover the course as part of their all-encompassing pathway towards becoming an electrician. This well-taken route sees candidates navigate through a range of C&G modules, before acquiring fully-fledged electrician status at the conclusion of their programme. This is an option generally favoured by school leavers, as it facilitates employment experience with continued collegiate study. In this way, apprentices can learn ‘on the job’ and pick up some income, whilst completing their qualifications in a controlled, academic environment.

Furthermore, as training is sponsored by their employer, there is no significant cost outlay for those attending apprenticeship schemes. Therefore, although individuals will not receive a fee close to a normal full-time salary, a sizeable amount is saved in learning expenditure. Businesses can apply for a government grant to support their apprenticeship endeavours. This may result in some employers having some extra funds to compensate apprentices more handsomely for work undertaken. Indeed, gaining entry onto an apprenticeship scheme can be an extremely rewarding enterprise for young people. Ultimately, this can help secure future employment, provide favourable learning conditions, and offer tangible financial advantages.

‘Front-loaded’ training

Those qualifying through a ‘front-loaded’ route will usually pick up the full costs of their training modules. This can be an extremely expensive undertaking. The C&G 2365 Level 2 Electrical Installation Diploma alone can cost upwards of £4500, and this is just one of a host of compulsory courses.

Individuals who embrace this style of training will most likely be career-changers, who are typically well beyond student age. However, within both routes (apprenticeship and front-loaded), there is a substantial level of crossover between types of individuals participating. Certainly, not all will fit the stereotypical profiles articulated. Some may even have wound up taking a front-loaded pathway due to a lack of success in their applications for apprenticeship schemes. Regardless, there is no ‘preferred’ route. Both approaches, if deployed accurately, and implemented with success, will support individuals to become fully-qualified electricians.

One key benefit of exploiting the front-loaded training channel is the flexibility it offers. There is no ‘fixed’ guide as per the apprenticeship path, and candidates are free to address their learning in any way they please. Of course, this will still need to incorporate each module required in the acquisition of electrician status.

However, the training order, skills, certification provider, and learning institution can be selected independently. This means that certain modules can be prioritised, opening up immediate workplace opportunities and earnings scope. For example, a student may decide to undertake a PAT testing course, or a qualification in EV installation, before sitting their Level 3 NVQ. Therefore, individuals can to begin perform electrotechnical task compliantly, and be appropriately compensated for doing so. This opportunity would most likely not be afforded to apprentices. This is because they have largely rigid training plans, and will be committed to a specific employer who will determine workload and focus areas.

Which pathway is best for you?

Therefore, prospective course delegates need to clearly understand the characteristics of the ‘route’ they’re planning to embark on. In doing so, there’ll be able to make an informed decision on whether embracing a certain pathway is conducive to their personal circumstances.

Course context

Most learning facilitators will offer this qualification either in isolation, or as part of a combined 2365 course. This would amalgamate Level 2 learnings, with the information received on its Level 3 counterpart. By undertaking both modules in one sitting, delegates can reduce costs, time, and future duplication of content. True, the 2365 Level 2&3 Diploma offers a streamlined version of each course, without compromising on quality of information. Therefore, in most cases, candidates are encouraged to pursue the combined package.

Although the Level 2 Electrical Installation Diploma is recognised as the first training step, it’s worth noting that having a foundation knowledge of electrotechnical theory is preferred. Some learning providers will offer taster sessions or supporting contacts to liaise with. These will help determine whether a career in the electrical industry is something you would definitely like to consider. However, some low-key, private research will most likely be sufficient, and provide enough information to make a decision.

Domestic Installers Course

There is also the option of attending a Domestic Installers Course, but this is usually reserved for those with slightly different career aspirations. The Domestic Installer programme is aimed at those looking to provide basic residential services, as opposed to operating commercial and industrial electrical installations.

Taking this qualification before later moving onto the Level 2 Diploma would be a substantial waste of time and money. If you have realistic ambitions of becoming a fully-fledged electrician, than this diploma cannot be skipped. As there is heavily duplication between both courses, and each carries an individual fee, taking the domestic installers module would, in this scenario, be therefore a completely pointless endeavour. There are easier, more efficient ways of gaining an understanding of the basic, theoretical information required to progress. Apprentices shouldn’t contemplate attending this training, as all required foundation knowledge is secured on their respective training scheme.

Course content and structure

Although in effect an introductory qualification, the 2365 Level 2 Electrical Installation Diploma still touches upon some fairly complex themes. Candidates should therefore be prepared to engage fully in course content, otherwise risk being left behind. As well as delving into electrotechnical theory, there is also substantial focus on health and safety considerations. Each element is gradually progressed further as students meander onwards through their training journey.

Furthermore, some delegates may decide to halt their learning progress at this juncture. This is because successfully passing this course permits individuals to become an ‘electrician’s mate’. Although not a fully-qualified position, this occupation will allow workers to enter the electrotechnical industry in a formal capacity. In this role, individuals can assist fully-trained electricians in a number of routine activities, but need to be supervised at all times. Therefore, this occupation is relatively limited in scope.


In terms of structure, most providers will conduct courses over a period of ten ‘learning’ weeks (i.e., fifty days, within an extended timeframe). Apprenticeship schemes will intersperse this with practical work on-site, so the qualification will take a little longer to work through.

For front-loaded training participants, duration will be dependent on personal circumstances and available sessions. Course facilitators will most likely spread learning out over a five-month phase, but this may need to increase based on a delegate’s private commitments.

This serves to highlight another clear benefit for front-loaded training users. Providers, understanding their attendees may be currently in alternate employment or required at home, usually offer a high degree of flexibility and support. This allows candidates to control the pace, intensity and frequency of learning. Therefore, individuals can change career direction without having to compromise income, childcare commitments, or social time. Of course, the most productive approach is to work through the required qualifications with efficiency and effectiveness. However, the space afforded in this process works to reduce stress and inconvenience levels for certain participants.

Subject coverage

The course itself is segmented into two clear sections, with one e-learning based, and the other positioned around practical exercises. These parts represent two-fifths and three-fifths respectively. Therefore, e-learning will roughly account for twenty days, with the practical element lasting approximately thirty days. As referenced, course content is relatively diverse, and will cover the following topics:

Theory and classroom-based learning

  • Technology used in electrical installation
  • Key principles of electrical science
  • Wiring systems and enclosure installation
  • Gaining an understanding of renewable technology, and how recent advancements have positively impacted the electrotechnical industry
  • Gaining an understanding of the Part P Building Regulations
  • Acknowledging and understanding the role of the National Grid
  • Health and safety considerations in Building Services Engineering

Practical Skills

  • How to deploy armoured cable, steel & plastic conduits, cable trays and trunking
  • How to install PVC cables (twin, earth, and singles)
  • How to conduct basic inspection and testing.
  • How to replace consumer units
  • Basic understanding of lighting install and design
  • Gaining an appreciation of single and three-phase conductors
  • How to deliver domestic re-wiring
  • Fault diagnosis exercises
  • How to safely terminate data cables

Furthermore, the qualification will touch upon how to professionally interact with team members and leadership colleagues whilst on-site. Therefore, the course is also partially geared towards learning the right behaviours, not just around acquiring core skills and knowledge.

Specific modules within the course

In order to facilitate learnings on the subjects listed above, the C&G 2365 is infused with a number of other learning modules. Again, these can be taken as independent qualifications, but are more efficiently handled when addressed within the diploma’s framework. Below, we provide a brief overview of specific courses within the over-arching C&G 2365 Level 2 Electrical Installation structure.

Electrical Installation Work within a Domestic Dwelling

Learnings in this discipline will take place over roughly a five-day period. Students will gain an understanding on the fitting of standard household appliances, such as electrical cookers and consumer units. Furthermore, content will touch upon installations in more challenging environments, such as bathrooms and wet rooms. Here, specific approaches must be suitably undertaken to assure worker and client safety. This module also focuses on how to conduct a full, domestic re-wiring. This is a process required every twenty-five to thirty years, and involves a comprehensive system upgrade to better serve electrical appliances in the home.

C&G 2393-10 Part P Building Regulations

This course walks delegates through information on the government’s Part P scheme. Back in January 2005, a new piece of legislation surfaced in connection to the instalment of electrical installations in domestic settings. This detailed that an electrician operating in a residential environment had to understand the potential impact of their work on building control functions. Ultimately therefore, electrical professionals were now expected to harness the same level of building knowledge as dedicated building management system contractors.

Individuals who have a Part P licence have demonstrated the required level of competency to conduct work in domestic dwellings, without requiring the input of the Local Authority Building Control Department (LABC). For those with licenses, they can plan, implement and self-certify works in residential environments. The only requirement is to inform the LABC when the task has been finished. For those without Part P licenses, who have therefore not acquired the demanded level of expertise, the route to job completion is far more protracted. Constant communication with the LABC is required before, during and after works. This causes delays, additional expenditure, and, in some cases, tangible customer frustration. Although sustaining a Part P license does in itself carry an annual charge, it’s a far more cost-effective process than entering LABC negotiations on every set of works.

Not all work conducted in domestic settings require a Part P license or LABC contact. The 2393-10 discusses examples of where and when this process is necessary. Crucially, the course sets candidates up in good stead for an onwards license application. These cannot be acquired by simply anyone! Individuals must be able to demonstrate knowledge in this field, and evidence suitable qualifications, such as this one, to support their application.

C&G 2382-18 Level 3 Award in Requirements for Electrical Installations bs7671: 2018 (18th edition)

This qualification provides detail on the bs7671 standards, which allude to the compliant implementation of any electrical works activity. This is a set of guiding principles that all electricians must adhere to. They address the way in which electrical instalments should be designed, installed, commissioned, and tested. In this way, the rules and regulations discussed on this course define how an electrical professional should approach, execute, and review their work. The IET wiring regulations guide is an all-encompassing piece of literature which supports the industry to establish, monitor, and update these practices. More information on this resource to follow.

The C&G 2392-10: Inspection and Testing

This qualification provides a comprehensive overview of the inspection and testing of electrical circuits and instalments. Content will be focused on the different disciplines within this space, including initial verification, visual inspection, periodic testing, and appropriate certification of passed electrical installations. However, it should be noted that this is just an introductory course. This should not be confused with the C&G 2392-50, the C&G 2392-51, or the combining of the two through the vehicle of the C&G 2392-52. These courses offer a far more robust study into the theories and practices of inspection and testing. More complex and challenging themes lay in wait on this topic. Candidates progressing through to the Level 3 Diploma will tackle more developed concepts within this discipline.

Towards the conclusion of the diploma, delegates will be need to take a series of assessments to demonstrate their capability in these areas. The structure consists of various practical and multiple-choice based exams. In order to prepare for these tests, and indeed to support learning throughout the programme, candidates are advised to obtain some specific resource materials. These are (with commentary) the following:

The IET 18th Edition Guide: Requirements for Electrical Installations (bs7671:2018)

This book is more commonly referred to as the ‘wiring regulations’ The IET, or Institute of Engineering and Technology, release these periodical guides to provide support and assistance to the electrotechnical industry. They also conduct research work on behalf of governments, and facilitate ministers to make informed policy decisions on relevant subject matter. This documentation outlines the rules, principles, and regulations around the wiring of electrical instalments. As alluded to, it’s a one-stop shop article that ensures adherence with the latest bs7671 standards, the benchmark for compliant electrical work. All electricians, regardless of experience or competency level, should always align knowledge to the latest version of this guide. This book is clearly deployed regularly during the C&G 2382-18 module.

The IET On-Site Guide (bs7671: 2018, 7th Edition)

This guide streamlines the content contained in the full 18th edition IET wiring regulations. However, this should not be used to cut corners or ‘substitute’ learnings. The main book should always be considered as the key reference document. However, if looking to quickly reflect on a specific principle, or in need of support when looking to swiftly identify an electrical formula or algorithm, the on-site guide can be an extremely useful tool. Again, this will be actively used throughout the C&G 2382-18 course.

The City and Guilds Textbook: Book 1 Electrical Installations for Level 2 Electrical Installation Diploma (2365).

This resource provides students with a number of supportive features. As well as relating course content and developing theory discussion, it also includes mock assessment questions. Furthermore, the guide offers hints and tips around expected industry values and behaviours in the workplace. This textbook perfectly complements the topics addressed throughout the qualification, and is a recommended purchase for all delegates.

Examination framework

As referenced, a series of assessments need to be undertaken at the conclusion of course. These assessments are designed to determine whether module learnings have been absorbed, and whether practical skill shave been honed to a reasonable level.

The testing schedule, with the exam format in brackets, is listed below:

  • 201: Health and Safety in Building Services Engineering (multiple-choice exam and one practical assessment)
  • 202: Principles of Electrical Science (multiple-choice exam)
  • 203: Electrical Installations Technology (multiple-choice exam)
  • 204: Installation of wiring systems and enclosures (practical assessment and accompanying questions)
  • 210: Understanding how to communicate with others within Building Services Engineering (multiple-choice exam)

Don’t be complacent!

All C&G multiple-choice exams have integrated flagging software, which often really helps delegates with their testing approach. Individuals can mark questions that initially feel challenging, and re-visit them at the conclusion of their assessment. In this way, students can retain their momentum throughout the test, and avoid the risk of leaving questions unanswered.

As always with multiple-choice exams, it’s important not to under-estimate their difficulty. Certain questions will require systematically working out each potential option, before providing an answer through the process of elimination. Don’t assume that it will just test pre-determined knowledge! Often, theories, formulas and principles will need to be applied to discover answers through a methodical approach.

Approaching practical tests

Practical assessments can often be impacted by nerves on the day. The key thing to remember here is that the skills you’re being asked to demonstrate will have been already learned, practiced and refined on your training. Therefore, to some extent, you should be able to rely on muscle memory when you’re performing in exam conditions.

For those tasks that are proving a little more challenging, just try to relax and stay calm. The reason you’re in this position is because you’ll have demonstrated the relevant capability in the past. Tutors and course facilitators are not keen on progressing individuals they don’t believe will overcome the assessment. This could compromise their pass rate! Therefore, be confident in your own ability, and embrace the assessments with assurance and positivity.

Once all of these testing elements have been successfully navigated, delegates will be awarded their C&G 2365 Level 2 Electrical Installation Diploma.


As we’ve seen, this course contains a number of rudimentary electrotechnical themes that will form the basis of future learning. The content covered offers detail on numerous crucial theories and practices of the electrical trade. This includes information on inspection and testing, wiring regulations, industry equipment, Part P licensing, fault-finding, and relevant residential works.

More often than not, candidates will embrace the Level 2 Electrical Installation Diploma in conjunction with the Level 3 module. From here, they will most likely progress onto the C&G 2357 Level 3 NVQ/AM2. However, one must remember that it may suit some industry students to attend this course in isolation. This could be due to personal circumstances, or because a career as an ‘electrician’s mate’ is targeted. However, to re-emphasise, the most cost-effective route to becoming a fully-qualified electrician, is to do so via a combined 2356 qualification.

Be prepared, and don’t be afraid to ask for support

Whether this course is attended in an apprentice capacity, or by someone engaging in a ‘front-loaded’ training plan, it must be navigated successfully in order to progress onto the Level 3 NVQ stage. Therefore, the accompanying assessments must be taken seriously. This will involve attentiveness to course content, a solid revision schedule and strong focus on supportive resources. Particular attention should be given towards the IET wiring regulations, which serve to form the cornerstone of electrical theory and practice. Remember, through good preparation, positivity, and a cool head on the day, delegates should feel confident in passing their Level 2 assessments.

This article has hopefully enabled readers to ingratiate themselves with the key information surrounding the C&G 2365 Level 2 Electrical Installation Diploma. By providing analysis of course content, structure, and format, prospective candidates should feel better equipped to approach this qualification. If any further detail or support is required, please liaise with either an industry professional, or a tutor skilled in electrical practice. Alternatively, solid guidance is offered on the relevant City and Guilds webpage, which can be found here.

We wish you the best of luck in attending your C&G 2365 Level 2 Electrical Installation Diploma, and also, perhaps more importantly, with its subsequent assessments!
