What Will You Learn on the Battery Storage Course?
The City & Guilds Level 3 Award (2923-34) has been developed to give qualified electricians the knowledge and practical skills required to work safely with Small Electrical Energy Storage Systems (EESS).
By the end of the course you will understand how to design, install, inspect, test and commission battery storage systems in accordance with current legislation, the IET Code of Practice and BS 7671.
Unlike many introductory renewable energy courses, this qualification focuses on the complete installation process, from the initial design through to final commissioning and client handover.
Course Syllabus
The course combines classroom theory with practical learning to build confidence when working with battery storage systems.
Introduction to Electrical Energy Storage Systems
You’ll begin by understanding how battery storage integrates into today’s electrical installations.
Topics include:
- The role of battery storage within renewable energy systems

- Maintenance advice
- Warranty documentation
- Certification
- Emergency shutdown procedures
A thorough handover improves customer confidence while helping reduce future support calls.
Assessment
Assessment is designed to confirm both your theoretical knowledge and your practical competence.
The qualification includes:
Online Knowledge Test
You’ll complete an online multiple-choice examination covering:
- Legislation
- Battery technologies
- Installation practices
- Design
- Inspection
- Testing
- Commissioning
Practical Assessment
You’ll also complete a practical assignment where you’ll demonstrate your ability to:

- Carry out testing
- Commission the system
- Complete documentation
Successful completion of both assessments leads to the award of the City & Guilds Level 3 Award in the Design, Installation and Commissioning of Small Electrical Energy Storage Systems (2923-34).
Entry Requirements
This qualification is intended for qualified electricians.
You should normally hold a recognised Level 3 electrical qualification and have experience of electrical installation work.
Many learners will already hold qualifications such as:
- City & Guilds Level 3 Electrical Installation
- NVQ Level 3 Electrotechnical Qualification
- 18th Edition Wiring Regulations
- City & Guilds 2391-52 Inspection & Testing
If you’re unsure whether your qualifications meet the entry requirements, our team will be happy to review your existing certificates and advise on the most suitable pathway.
Applicants can send copies of their qualifications before booking, allowing Training Solutions NI to confirm eligibility and recommend any additional qualifications that may be beneficial before attending the course.
What Qualification Will I Receive?
On successful completion you will achieve the:
City & Guilds Level 3 Award in the Design, Installation and Commissioning of Small Electrical Energy Storage Systems (2923-34)
This nationally recognised qualification demonstrates that you have the knowledge and practical skills required to work safely with small electrical energy storage systems in domestic and small commercial environments.
The demand for electricians with renewable energy skills continues to grow across Northern Ireland. As battery technology becomes more widely adopted, installers who can safely design and commission Electrical Energy Storage Systems (EESS) are becoming increasingly valuable to both domestic and commercial clients.
Completing the City & Guilds Battery Storage qualification allows you to expand the services you offer and support customers who are investing in renewable technologies.
Many electricians who complete this qualification go on to work on:
- Domestic battery storage installations
- Commercial energy storage systems
- Solar PV and battery storage packages
- Smart home energy management systems
- Electric vehicle charging installations
- Renewable energy projects
- Property developments
- Energy efficiency upgrades
For electrical contractors, adding battery storage to your portfolio can help secure additional work from existing customers while opening opportunities in the rapidly growing renewable energy sector.
Why Electricians Are Adding Battery Storage to Their Services
Battery storage is no longer a specialist niche. It is becoming part of a complete electrical solution.
Homeowners increasingly want a single contractor who can install:
- Solar PV
- Battery storage
- EV charging
- Consumer unit upgrades
- Smart controls
- Electrical testing and certification
Rather than using multiple contractors, many customers prefer one qualified electrician who can complete the entire installation.
This qualification helps position you to meet that demand.
Battery Storage and Solar PV – What’s the Difference?
Many people assume battery storage and Solar PV are the same. They are closely linked but serve different purposes.
| Solar PV | Battery Storage |
|---|---|
| Generates electricity from sunlight | Stores electricity for later use |
| Produces energy during daylight hours | Supplies stored energy when required |
| Reduces reliance on the grid | Increases use of self-generated electricity |
| Requires suitable inverter technology | Uses dedicated battery management systems |
| Can operate without battery storage | Often installed alongside Solar PV for maximum benefit |
Many new installations now combine both technologies to increase energy efficiency and reduce electricity costs.
For electricians, understanding both systems creates more opportunities and allows you to offer complete renewable energy solutions.
