What Is the OZEV Workplace Charging Scheme and Who Qualifies?

The Workplace Charging Scheme (WCS) is the OZEV grant for commercial EV charger installations. It provides up to £350 per socket toward purchase and installation — applicable to businesses, charities, and public authorities with dedicated off-street parking. Key details:

Maximum 40 sockets per application, up to £14,000 per organisation
Applies to OZEV-approved smart chargers with a minimum 7.4kW rated output
Your installer (us) applies for the voucher on your behalf before installation
Eligible for both new-build and retrofit commercial installations
Cannot be combined with some other public funding streams — we advise on compatibility during site survey

The WCS is available via the gov.uk Workplace Charging Scheme portal. We handle the application process and you pay only the net cost.

Why Does Fleet EV Charging Need Load Management?

Installing 20 × 22kW chargers at a fleet depot implies a 440kW peak demand — requiring an HV grid connection that may cost £50,000–£200,000+ and take months to install. Smart load management solves this: a management system monitors real-time demand across your site and dynamically allocates available capacity to each charger. When a vehicle is plugged in overnight, it receives only the share of capacity available — often 3–5kW — but since vehicles dwell for 8+ hours, they fully charge regardless. The system can also prioritise vehicles leaving earliest, integrate with tariff schedules for off-peak charging, and export data to your fleet management software.

Greentech Renewables designs load-managed systems that allow you to install significantly more charge points than your existing grid connection would otherwise support — often eliminating the need for a DNO upgrade entirely.

Frequently Asked Questions — Commercial EV Charging

How much does commercial EV charger installation cost?

£1,200–£5,000 per bay for 7.4kW–22kW AC units. DC rapid chargers cost £15,000–£30,000 per unit. Multi-bay installations attract economies of scale. The OZEV WCS grant provides up to £350/socket, up to £14,000 per organisation.

What is the OZEV Workplace Charging Scheme grant?

A government grant providing £350 per EV charging socket for businesses, charities, and public authorities. Max 40 sockets (£14,000) per organisation. We apply on your behalf before installation begins.

What is load management and why does my business need it?

Load management distributes available electrical capacity across multiple chargers to prevent grid overload — enabling more charge points without expensive DNO connection upgrades. Essential for fleet depots installing 10+ bays on an existing connection.

Can commercial EV chargers integrate with solar panels?

Yes. We design combined commercial solar + EV charging systems that divert surplus solar to vehicles — reducing per-kWh charging cost and peak grid draw.

What is the difference between AC and DC commercial EV charging?

AC chargers (7.4kW–22kW) are for dwell parking (overnight fleet, workplace day parking). DC rapid chargers (50kW+) provide 100+ miles in 20–30 minutes for high-throughput sites. Most fleet and workplace scenarios are best served by 22kW AC with load management.

Do I need planning permission for commercial EV chargers?

Standalone charger posts in existing car parks usually fall under permitted development. Larger installations or canopy structures may require planning. We advise during the site survey.

Can employees or customers pay for EV charging?

Yes. Smart chargers support RFID access (for employees), app payment, and contactless bank card payment. Management platforms allow tariff setting, usage reporting, and automated billing — generating revenue for car park operators.

What is the ZEV mandate and how does it affect fleet planning?

The UK Zero Emission Vehicle mandate requires 80% of new car sales to be electric by 2030 and 100% by 2035. Fleet managers must plan EV charging infrastructure now to avoid rushed installation costs and grid connection delays as adoption accelerates.
