Workplace EV charging installation cost depends on how many sockets you need, how close the electrical supply is to the bays, and whether you add access control or visitor billing. Small AC staff schemes on an existing board can be comparatively contained, while larger car parks need distribution upgrades and civil works that dwarf the charger hardware. OZEV workplace support may reduce eligible per-socket costs for qualifying organisations, subject to live caps and limits. Compare surveyed written scopes before approving a rollout.
Start with the use case
Staff who park all day need fewer kilowatts per bay than delivery vans that turn around at lunchtime. Visitor spaces may need open-access payment. Mixing those needs on one quote without labelling them creates confusion and change orders.
Count realistic concurrent charging, not total parking spaces. Load management lets more bays share limited supply.
Cost drivers employers underestimate
Cable routes across live car parks, evening or weekend working, temporary traffic management and making-good of tarmac often exceed the wallbox line item. Networking for smart chargers in thick-walled buildings is another quiet extra.
Internal electrical capacity surveys should come early. Discovering a weak sub-main after hardware is ordered is an expensive sequence.
- Electrical: spare capacity, new circuits, isolation and metering
- Civils: ducts, pedestals, impact protection, bay painting
- Operations: RFID or app access, expense reclaim rules, maintenance
Grant-aware budgeting
UK workplace chargepoint grants have offered a contribution per eligible socket up to a published maximum, with limits on how many sockets an organisation can claim across sites. From April 2026 guidance, rates and application routes were refreshed again, so finance teams should use GOV.UK rather than older blog posts.
Model the business case both with and without grant income. If eligibility fails or funding closes, the project should still make operational sense.
Single site versus multi-site programmes
Multi-site employers benefit from a standard specification: same charger family, same load-management approach, same user app. That reduces training and spare parts cost even if each site needs different civils.
Ask installers for a framework-style unit rate plus site-specific extras, then compare those extras carefully via a shared quote process.
Health, safety and equality
Accessible bay design, lighting, cable management and clear signage belong in the first design, not as a retrofit after complaints. Inclusive design avoids later remedial spend and supports staff who rely on workplace charging.
Frequently asked questions
How many workplace sockets do we need?
Begin with staff EV counts, shift patterns and survey interest, then add a buffer for growth. Concurrent demand matters more than one socket per parking space.
Can employees claim tax relief somehow?
Tax treatment of workplace charging benefits can be specific and has changed over time. Employers should take current HMRC guidance rather than assume home-charging rules apply.
Is 7kW enough at work?
For full-day staff parking, often yes. For short-stay fleet turns, higher AC or DC may be justified if the vehicles and supply support it.
Who maintains workplace chargers?
Build a maintenance and fault-response contract into the purchase. Downtime frustrates staff quickly and is harder to fix without remote monitoring.
