Frequently Asked Questions
Everything you need to know about the Level 3 Diploma programme. Can’t find your answer? Get in touch for a free consultation.
Yes. The standalone Level 3 requires the C&G 2365 Level 2 Diploma or an equivalent Level 2 qualification. If you don’t yet have Level 2, our Combined Level 2 & 3 programme lets you complete both in a single 24-week enrolment — speak to our team to find out which route is right for you.
The programme is 16 weeks of blended learning — combining online self-study through our learning portal with regular practical centre sessions at our London (Isleworth) or Manchester (Hyde) locations.
The standalone Level 3 is for those who already hold the Level 2 Diploma. The Combined Level 2 & 3 programme is for those who need both qualifications — covering Level 2 in weeks 1–10 and Level 3 in weeks 11–28 as a single 28-week enrolment at £5,800 + VAT. If you already have Level 2, the standalone Level 3 at 16 weeks is the right option.
The programme covers all 7 units of the C&G 2365-03: Unit 201 (Health & Safety), Unit 301 (Environmental Technology Systems), Unit 302 (Principles of Electrical Science Level 3), Unit 303 (Fault Diagnosis & Rectification), Unit 304 (Inspection, Testing & Commissioning), Unit 305 (Electrical Systems Design), and Unit 308 (Career Awareness in BSE).
With both Level 2 and Level 3 diplomas you meet the knowledge entry requirement for the NVQ 2357. You’ll also need the 18th Edition (C&G 2382) before starting the NVQ. On completion of the NVQ you can apply for your ECS Gold Card — the industry-recognised proof of full electrical competency.
The Level 3 Diploma is £2,950 + VAT (reduced from £3,300 + VAT). A £500 deposit secures your place, with the balance payable over 3, 6 or 12 months. Speak to our team for full details on payment plans.
Blended learning combines online self-study through our learning portal with regular practical centre sessions at our London (Isleworth) or Manchester (Hyde) centres. You study theory and knowledge units online at your own pace, then attend centre days for hands-on practical training and assessments. Our tutors support you throughout — both online and in person.
The Recognition Programme is for experienced workers who want to formalise their Level 3 skills. If you have significant electrical industry experience, you may be able to fast-track or gain credit exemption for parts of the programme. Every application is assessed individually — get in touch for a free consultation and we’ll tell you exactly what applies to your situation.
Yes. Practical centre sessions run at both our London centre in Isleworth and our Manchester centre in Hyde. You choose your preferred location at enrolment. The online learning element can be completed from anywhere — only the practical sessions require you to attend in person.
