OZEV Workplace Charging Scheme: How To Apply And Qualify Business Parking Spaces

The Workplace Charging Scheme (WCS) is a voucher-based program designed by the UK government's Office for Zero Emission Vehicles (OZEV) to reduce the upfront purchase and installation costs of electric vehicle (EV) smart chargers by 75%, up to a maximum of £350 per socket. Eligible businesses, charities, and public sector organisations can secure funding for up to 40 sockets, yielding a maximum grant value of £14,000. To successfully qualify, applicants must demonstrate dedicated, off-street business parking spaces and use an OZEV-authorised installer to commission approved smart chargepoint hardware.

Pre-Application Audit: OZEV Eligibility and Technical Requirements

Before initiating an online application for the Workplace Charging Scheme, businesses must conduct a comprehensive operational and site survey. Failing to verify electrical capacity, property deeds, or corporate registration parameters prior to application often leads to immediate voucher rejection or costly installation delays.

Mandatory Prerequisite Standards and Compliance Criteria

• Corporate Identification: Applicants must possess a valid Companies House registration number, a VAT registration number, or official proof of charity/public sector status. Sole traders must provide a registered business address and proof of HMRC self-assessment registration.
• Property Ownership and Tenure: The business must either own the property or hold a lease with explicit written consent from the landlord for electrical installations.
• Off-Street Parking Mandate: Eligible parking spaces must be off-street, dedicated solely to staff, fleet, or visitor use, and situated within or adjacent to the business premises. On-street, public, or residential parking spaces do not qualify.
• Hardware and Installer Authorisation: The project must use hardware models listed on the OZEV-approved chargepoint list and be installed by an OZEV-approved installer. Self-installation or using unapproved contractors invalidates the voucher.

Technical, Material, and Budgetary Benchmarks

• Required Documentation: Land Registry title deeds or a signed lease agreement, a recent energy bill for MPAN (Meter Point Administration Number) verification, and a signed landlord consent letter if the premises are leased.
• Electrical Infrastructure: A minimum single-phase 230V connection is required for 7.4 kW chargers. A three-phase 400V supply is necessary if installing 11 kW or 22 kW commercial chargers to prevent overloading the local network.
• Estimated Duration: The online application takes approximately 15 to 30 minutes to complete. Once approved, the OZEV voucher is valid for exactly 120 days from the date of issue, during which installation and claims submission must occur.
• Budgeting Realities: While the grant covers up to 75% of costs (capped at £350 per socket), businesses must fund the remaining 25% of hardware and installation costs, plus any necessary civil engineering works, ground trenching, or grid upgrade fees imposed by the Distribution Network Operator (DNO).

Step-by-Step Application and Installation Framework

Successfully claiming the OZEV grant requires close cooperation between your internal facility team and your chosen OZEV-authorised electrical contractor. Follow this structured process to secure approval and complete the installation.

Step 1: Verify Parking Space Eligibility and Land Rights

Assess your designated business parking bays to confirm they meet OZEV’s strict definitions of dedicated off-street parking. Each parking space destined for a charger must be clearly associated with your business premises.

If your business operates from a shared commercial estate or multi-tenant facility, you must secure a written agreement that designates specific bays for your exclusive use. Ensure there are no public rights of way cutting through the parking zone. Obtain the Land Registry title plan for your property, highlighting the exact boundary where the physical charging units will stand. If you are leasing, draft a formal Landlord Consent Letter specifying the scope of work, cable routing, and the installation of distribution boards.

Step 2: Select an OZEV-Authorised Installer and Perform a Site Load Survey

Navigate to the official list of OZEV-approved chargepoint installers and contact a certified contractor. Do not instruct them to install any equipment before securing your voucher, but do request a professional site survey.

The installer must inspect your main incoming electrical panel to determine if your existing supply can handle the additional load of the planned EV sockets. For example, installing four 7.4 kW chargers adds a potential load of 128 Amps (29.6 kW) to your system. The installer will evaluate whether dynamic load balancing is required to prevent tripping your main fuses. They will also determine whether a DNO notification (G99 or G100 connection application) is necessary, which is common when adding substantial electrical load to commercial properties.

Step 3: Complete the OZEV Workplace Charging Scheme Online Application

Access the official UK government WCS portal to submit your electronic application. Ensure that the company details you enter exactly match your registration records at Companies House.

During the application process, you must specify the exact number of sockets you intend to install immediately, as well as any future provisions up to the limit of 40 sockets. Prepare to upload your supporting documents, including your company registration number, proof of parking space ownership or lease agreements, and your state aid/subsidy control declaration. Under current UK subsidy control rules, you must declare any public funding your business has received over the last three fiscal years to ensure compliance with threshold limits.

Step 4: Receive, Verify, and Forward the OZEV Voucher

Upon successful assessment of your online application, OZEV will generate a unique WCS voucher code via email. This code acts as a financial commitment from the government to subsidise the installation.

Inspect the voucher details immediately to ensure your business name, address, and approved socket allocation are correct. Forward this voucher code to your chosen OZEV-authorised installer. Note that the voucher has a strict 120-day expiration window. If civil works, DNO permissions, or hardware lead times threaten to push the installation date past this deadline, you must coordinate with OZEV or prepare to submit a new application prior to starting any physical works.

Step 5: Execute Physical Installation and Complete Installer Commissioning

Your authorised installer will now mount the smart chargers, lay the electrical cabling, and connect the units to your distribution boards.

Warning: All chargepoints funded under the WCS must meet the UK Smart Charge Points Regulations. This means they must support smart functionalities, including off-peak charging capabilities, randomized delay starts, and secure data encryption.

Following physical installation, the contractor will commission the units and verify their active internet connection, which is required for smart data transmission. The installer will then claim the £350 rebate per socket directly from OZEV on your behalf, deducting this amount from your final invoice. Keep all commissioning certificates, DNO approval letters, and the final invoice on file for at least three years, as OZEV routinely conducts site audits to verify compliance.

Infrastructure and Electrical Specification Options

When configuring your business parking spaces for EV charging, choosing the appropriate power output and cabling infrastructure is critical to long-term operational success. The table below details the technical specifications, requirements, and use cases for the three standard commercial charging levels eligible under the Workplace Charging Scheme.

Common Application Rejections and Site Constraints

Applying for the Workplace Charging Scheme can occasionally present challenges. Below are real-world failure scenarios that businesses frequently encounter, along with the precise technical adjustments needed to resolve them.

Scenario 1: Rejection Due to Ambiguous Parking Space Ownership

• Root Cause: The application was rejected because the uploaded lease agreement did not explicitly state that the applicant has exclusive rights to the specific parking spaces marked for installation, raising concerns about public or shared access.
• Actionable Fix: Request an official addendum to your lease from your landlord. This document must state that the designated bays are reserved for the sole use of your employees, visitors, or fleet. Alternatively, obtain a signed letter on corporate letterhead from the property owner confirming your exclusive parking rights and submit this along with your Land Registry deeds.

Scenario 2: Distribution Network Operator (DNO) Connection Refusal

• Root Cause: The local DNO blocked the installation of multiple 22 kW chargers because the local substation is near maximum capacity, creating a risk of grid instability during peak business hours.
• Actionable Fix: Instruct your installer to integrate a dynamic load management system (DLMS). This technology automatically throttles the charging speed of individual sockets when the building's overall power consumption spikes. Submit the revised system design, featuring G100 load-shedding compliance, to the DNO to secure grid connection approval.

Scenario 3: Expiry of the 120-Day Voucher Window

• Root Cause: Delays in obtaining specialist hardware or securing trenching contractors caused the installation to slide past the 120-day voucher validity period.
• Actionable Fix: Do not attempt to claim an expired voucher, as OZEV's automated system will reject it. You must submit a brand new application through the online portal. To ensure approval, upload updated quotes and confirm that your installer can schedule the work within the new 120-day window.

Scenario 4: Shared Metering Complexities in Serviced Offices

• Root Cause: The application was flagged because the commercial property uses a single shared MPAN (Meter Point Administration Number) across multiple independent businesses, making it difficult to verify individual energy usage.
• Actionable Fix: Install a sub-meter dedicated entirely to the EV charging distribution board. Provide OZEV with a comprehensive schematic of the electrical layout, demonstrating that your business pays for the EV charging consumption, even if it is billed via a service charge managed by the landlord.

Frequently Asked Questions

Can I apply for the OZEV WCS if I run a business from home?

You can apply only if your home address is officially registered as your primary place of work with Companies House or HMRC. Additionally, your home must have a designated, off-street business parking space that is not part of a shared domestic driveway, and you must prove that your business vehicles or staff regularly use this parking space for commercial purposes.

How many charging sockets can my business claim under the scheme?

A single business can claim a maximum of 40 charging sockets under the Workplace Charging Scheme. These sockets can be distributed across one commercial site or spread over multiple offices, warehouses, and depots, provided that each location meets the off-street parking and usage requirements.

Does the OZEV grant cover the cost of electrical grid upgrades?

No, the OZEV grant does not cover the cost of upgrading your local electricity supply or installing new substations. The voucher is capped at 75% of the cost of the charging units and their physical installation (up to £350 per socket), meaning any upstream distribution network upgrades charged by your DNO must be funded entirely by your business.

Can landlords apply for the Workplace Charging Scheme on behalf of tenants?

Landlords can apply for the scheme, but they must demonstrate that the chargers are being installed to support a specific tenant's staff or fleet. Landlords can also access a dedicated residential carpark grant if they are installing infrastructure in multi-unit residential blocks, which operates under a separate set of OZEV guidelines.

What happens if we relocate our business after installing the chargers?

If your business relocates within three years of receiving the funding, you must notify OZEV of your move. Because the grant is tied to the physical site where the installation was validated, removing the chargers or transferring them to a new site without OZEV’s written permission may result in a clawback of the grant funds.
