EV Charging for Workplaces: A Guide for UK Employers

Perhaps an employee has asked whether they can charge their new electric car in the office car park. Or your business may be replacing fleet vehicles and discovering that public charging alone will not provide the reliability your team needs.

Installing EV charging at workplaces can solve both problems, but the right system depends on more than the number of parking spaces available. You will need to consider how long vehicles remain on site, the building’s electrical capacity, who will use the chargers, and how demand may change.

This guide explains the benefits, charger options, costs, grants, compliance requirements, and practical decisions involved in planning workplace charging in the UK.

Is workplace EV charging worth installing?

For many employers, it is. Workplace charging gives employees and business vehicles access to dependable charging during hours when cars or vans would otherwise be parked.

The strongest business case comes from matching the system to a genuine use pattern. An office where cars remain parked for eight hours has very different requirements from a delivery depot where vans need to return to the road quickly.

A professional survey for commercial workplace charging installations should therefore consider parking duration, expected mileage, electrical capacity, charger locations, and likely future demand before equipment is selected.

A practical route from interest to installation

Start by estimating how many employees or fleet vehicles need to charge now, how that figure may change over the next three to five years, and how long those vehicles usually remain parked.

EVC Installs can then assess the premises, discuss suitable charger positions, review available capacity, and recommend an appropriate setup. This provides a clearer basis for a detailed quotation and helps avoid choosing equipment purely because it is the cheapest or fastest option.

What are the main benefits of EV charging at work?

• Greater convenience for employees: Staff can charge while they work, which is particularly useful for people living in flats, rented homes, or properties without off-street parking.

• A flexible workplace benefit: Employers can offer free, subsidised, or paid charging, with separate rules for company and privately owned vehicles.

• More reliable fleet charging: Businesses can plan charging around shifts, routes, and vehicle downtime instead of relying on public charging availability.

• Support for sustainability goals: Managed chargers can record electricity use and help businesses monitor how vehicles use the system. For more detail, explore the benefits of workplace EV charging.

• Potential tax advantages: Qualifying workplace charging will not normally create a taxable benefit when HMRC conditions are met and access is generally available to all employees. Different rules may apply when reimbursing private charging away from the workplace.

Which type of workplace EV charger do you need?

The right commercial EV charging solution depends on parking time, vehicle mileage, available power, and budget.

• 7kW AC chargers: A practical option for offices where vehicles remain parked for several hours. They place less demand on the electrical supply, and several 7kW sockets may serve staff better than fewer faster units.

• 22kW AC chargers: Better suited to shorter stays or vehicles needing more charge between journeys. They usually require a three-phase supply, and the vehicle must support 22kW AC charging.

• Rapid DC chargers: Designed for high-mileage fleets, taxis, logistics, and quick vehicle turnaround. They cost more and may require significant electrical upgrades, so they are rarely needed for a standard office.

See the guide to commercial EV charger types for a closer comparison, or browse EVC Installs’ available EV charger options.

What affects the cost of workplace EV charging?

There is no reliable flat price for a commercial installation because the charge points are only one part of the project.

The final cost may be affected by:

• The number and power rating of the chargers

• The distance between the electrical supply and parking spaces

• Groundworks, trenching, posts, barriers, or wall mounting

• Distribution-board changes and protective equipment

• The available electrical capacity

• Load-management and back-office software

• Mobile-data or network connectivity

• Signage, bay markings, and accessibility requirements

• Future cable routes and expansion capacity

• Ongoing software, maintenance, and support charges

How should you plan an EV charger installation for businesses?

A successful workplace EV charger installation starts with how vehicles use the site, not with a preferred charger model.

• Assess demand: Count current EVs, estimate future growth, and separate staff, visitor, pool, and fleet vehicles. A car parked all day may need less power than a van charging between shifts.

• Check electrical capacity: An installer should assess the incoming supply and existing building demand. Load management can share available power between chargers and may reduce the need for an immediate supply upgrade.

• Set access rules: Decide whether charging is controlled by app, card, PIN, or vehicle registration. Confirm who can charge, whether payment or booking is required, whether fleet vehicles take priority, and how overstaying will be managed.

• Plan for expansion: A phased installation can provide the chargers needed now while preparing ducts, cable routes, distribution equipment, and communications for later growth. This can avoid reopening a completed car park in future.

What EV charging grants are available to UK workplaces?

The main option among current EV charging grants UK employers can consider is the Workplace Charging Scheme.

Eligible businesses, charities, and public-sector organisations may receive up to 75% of qualifying purchase and installation costs. For installations completed from 1 April 2026, support is capped at £500 per socket and 40 sockets across all sites.

The employer applies first, then gives the voucher to an OZEV-authorised installer, who deducts the grant and submits the claim.

Eligibility, approved equipment, installer status, and deadlines should be confirmed before committing to an installation.

What rules and compliance requirements apply?

Workplace charge points form part of the property’s electrical installation and should be designed, installed, tested, and certified by appropriately qualified professionals.

Relevant considerations may include:

• Current wiring regulations and EV-specific installation requirements

• Earthing and protective devices

• Smart-charging requirements for affected private workplace chargers

• Building Regulations and notification requirements

• Planning restrictions for listed buildings or sensitive locations

• Accessibility and safe positioning

• Impact protection where chargers face moving vehicles

• Fire risk, cable routes, signage, and pedestrian movement

• Distribution Network Operator notification or approval

• Data protection where user accounts or vehicle data are recorded

Approved Document S also sets infrastructure requirements for certain new and substantially renovated non-residential buildings in England. Existing premises are not automatically subject to every new-build requirement, but refurbishment or development projects should be checked carefully.

Requirements can vary by nation, building type, location, and project scope, so compliance should be confirmed for the individual site rather than treated as a standard checklist.

How can you manage employee and fleet charging?

As more vehicles connect, software and usage policy become as important as the chargers themselves.

A suitable management platform may allow the employer to:

• Restrict access to approved users

• Set different tariffs for staff, visitors, and fleet vehicles

• Monitor energy consumption

• Export transaction or reimbursement records

• Schedule charging outside peak periods

• Prioritise operational vehicles

• Detect faults remotely

• Balance available power across several sockets

For a small office, a straightforward access-control system may be enough. A mixed fleet and staff car park may need separate user groups, cost centres, and priority rules.

Choose the management platform with the same care as the physical charger. Check subscription costs, contract terms, payment fees, reporting functions, connectivity, technical support, and whether data can be exported if the business changes provider.

Plan your workplace charging installation

A site assessment can help you establish how many chargers are practical, which power ratings suit your vehicles, and whether load management or grant support should form part of the proposal.

Frequently asked questions

How many EV chargers does a workplace need?

Base this on current demand, future growth, and parking duration. Shared chargers may be enough where vehicles remain parked for several hours.

Can employers charge staff to use workplace EV chargers?

Yes. Charging can be free, subsidised, or paid, with clear tariffs, access rules, and accurate usage records.

Is free workplace EV charging a taxable benefit?

Usually not where HMRC conditions are met and charging is available at or near the workplace. Different rules may apply to off-site charging reimbursements.

Can the Workplace Charging Scheme cover the full cost?

No. It covers up to 75% of eligible costs, subject to per-socket and overall limits. Employers pay the remaining balance and any non-eligible costs.

Are 7kW chargers suitable for workplaces?

Often, yes. They work well where vehicles stay parked for several hours. Faster charging may suit short-stay users or demanding fleet schedules.
