Large-Scale EV Charging

Specialise in Commercial and Rapid EV Charging Infrastructure

The City & Guilds 2921-32 and 2921-33 combined course is the UK’s leading qualification for electricians and engineers working on large-scale electric vehicle charging installations. This intensive 4-day programme covers the design, quality assurance, installation, and maintenance of medium-power rapid charging systems (50–90kW) and high-power charging systems (up to 350kW), including an introduction to Megawatt Charging System technology for heavy goods vehicles.

With the UK government targeting 300,000 public charge points by 2030 and commercial fleet electrification accelerating across every sector, qualified large-scale EV charging installers are in exceptional demand. This course positions you for the highest-value projects in the EV infrastructure market.

Who Is This Course For?

• Qualified electricians moving into commercial EV work — If you already hold the 2921-34 (domestic EV) qualification and want to take on higher-value commercial projects, this is your next step.

• Electrical engineers designing EV infrastructure — The course covers design principles, load calculations, and quality assurance for large-scale installations — essential knowledge for specification and sign-off.

• Contractors bidding for commercial EV contracts — Fleet depots, workplace charging, supermarket car parks, and motorway service areas all require installers with the 2921-32/33 qualification. This is a differentiator when tendering.

• Charge Point Operators (CPOs) and their contractors — Companies building and maintaining public rapid charging networks need qualified engineers across their supply chain.

What Sets This Apart from the Domestic Course (2921-34)

The domestic EV course covers Mode 3 chargers up to 22kW for homes and small commercial premises. This large-scale course covers a completely different scope:

• Medium-power rapid charging (50–90kW) — DC rapid chargers for public locations, fleet depots, and workplace car parks

• High-power charging (150–350kW) — Ultra-rapid chargers for motorway service areas and public charging hubs

• Megawatt Charging System (MCS) — Introduction to the emerging standard for heavy goods vehicle and bus charging

• Three-phase power systems — Design and installation considerations for commercial electrical supplies

• Advanced load management — Dynamic load balancing across multiple high-power charge points

• Thermal management — Cooling systems and safety requirements for high-power charging equipment

Course Structure — 4 Days at Our Nottingham Centre

The course combines theoretical knowledge with practical application across four intensive days:

• Days 1–2: Design and Quality Assurance (2921-32) — System architecture, design calculations, quality assurance procedures, and compliance requirements

• Days 3–4: Installation and Maintenance (2921-33) — Installation procedures, commissioning, maintenance schedules, fault diagnosis, and health and safety

Assessment

Assessment consists of three components:

• Design and QA written exam (90 minutes) — Short-answer and scenario-based questions

• Installation and Maintenance written exam (120 minutes) — Short-answer and scenario-based questions

• Design project (3 hours) — A complete design exercise for a large-scale EV charging installation

Two City & Guilds Qualifications

On successful completion, you receive two separate City & Guilds certificates:

• Level 3 Award in the Design and Quality Assurance of Large-Scale Electric Vehicle Charging Installations (2921-32)

• Level 3 Award in the Installation and Maintenance of Large-Scale Electric Vehicle Charging Installations (2921-33)

Completing both units awards two City & Guilds certificates: the 2921-32 (Design and Quality Assurance) and 2921-33 (Installation and Maintenance) covering commercial car parks, workplace charging, fleet depots, and public rapid charging from 50kW to 350kW. The course carries the TESP Electrician Plus endorsement.

Who Is This Course For?

This course is for electricians who already hold the NVQ Level 3 and want to move into large-scale commercial EV charging infrastructure. It goes beyond the domestic 2921-34 qualification into three-phase rapid chargers, multi-point installations, and the design challenges of car parks, fleet depots, and public charging hubs. If you are tendering for commercial contracts, working with developers on new builds, or looking to specialise in the higher end of the EV market, this is the qualification that sets you apart from domestic-only installers.

What This Qualification Unlocks

The two units cover the full lifecycle of large-scale EV infrastructure. The 2921-32 (Design and Quality Assurance) covers site surveys, load assessments, power supply evaluation, cable routing and containment design, and quality assurance documentation. The 2921-33 (Installation and Maintenance) covers commissioning of rapid and ultra-rapid chargers, fault diagnosis, planned maintenance regimes, and compliance with the relevant regulations. The course covers systems from 50kW DC rapid chargers through to 350kW ultra-rapid units used at motorway services and public charging hubs. You will also learn about back-office systems, payment integration, and network management platforms used by commercial charge point operators.

Career and Earning Potential

Large-scale EV infrastructure is a premium specialism with significantly higher day rates than domestic work. Commercial EV projects typically pay £350 to £550 per day, and multi-day installations at car parks or fleet depots can run into the thousands. The UK government’s target of 300,000 public charge points by 2030 (up from around 70,000 today) means the market for qualified large-scale installers will continue to expand. Electricians who hold both the domestic 2921-34 and the commercial 2921-32/33 can work across the full range of EV installations, from home wall boxes to motorway rapid chargers.
