£500 Per Socket: Office EV Charging Checklist for Facilities Managers
Installing office EV charging is the right call for most employers with dedicated parking, because the Workplace Charging Scheme now covers a meaningful share of the cost. The first step is booking a site feasibility survey with an OZEV-authorised installer, who can confirm electrical capacity, parking eligibility and the grant amount available before you commit to hardware.
TL;DR:
The Workplace Charging Scheme now provides up to a fixed amount per socket for up to 40 sockets, with funding confirmed through March 2027, making installation more affordable.
Parking must be dedicated, off-road, and demonstrably allocated to staff or fleet use; shared or public areas often disqualify applications.
Chargers must meet strict technical standards, including the OZEV-approved model list, BS EN 61851 compliance, Type 2 connectors, and a minimum three-year warranty to qualify for grants.
Costs depend on site specifics such as civil works and supply upgrades, but the grant covers up to 75% of expenses, with a voucher validity of 180 days from issue.
Effective project sequencing involves early site feasibility and DNO checks, followed by grant application, design, civils, and installation to avoid costly rework and application failures.

Why office EV charging matters for your business
Workplace charging has moved from a “nice to have” to a genuine recruitment and retention lever. Staff who drive electric want somewhere reliable to plug in, and a growing number weigh it up before accepting a job offer. For fleet operators, it cuts fuel spend directly by shifting charging onto off-peak workplace electricity rather than public rapid chargers, which typically cost more per mile.
The business case stacks up in several ways:
Staff attraction and retention: EV-driving employees increasingly expect on-site charging as standard.
Fleet running costs: charging vans and pool cars overnight or during the working day beats relying on public networks.
ESG and tenant appeal: landlords and occupiers use chargepoint provision to strengthen sustainability credentials and lease attractiveness.
Ownership tends to follow one of three patterns: employer-funded and free to staff, employee-paid via a metered session fee, or a mixed model where a third party hosts and manages the hardware in exchange for a share of revenue.
Workplace Charging Scheme: what’s the grant and how do you apply?
The Workplace Charging Scheme (WCS), run by the Office for Zero Emission Vehicles (OZEV), is the main public grant supporting office EV charging in the UK, and the numbers just improved.
Grant headline: From 1 April 2026, the WCS pays up to a fixed amount per socket, up from £350 previously, and applicants can claim across up to 40 sockets covering all their sites combined. Funding is confirmed through to 31 March 2027.
Eligibility hinges on parking, not just business size. You need dedicated, off-road parking clearly associated with your premises, and it must be evidenced as belonging to your organisation rather than shared or public space. Landlord consent is required if you lease the site, and the scheme won’t fund general electrical upgrades unrelated to the chargepoints themselves.
The application and claim process runs in a set sequence:
Apply online through GOV.UK to confirm eligibility and receive a voucher code.
Instruct an OZEV-authorised installer to design and quote the installation, factoring the voucher into the price.
Complete installation within the voucher’s validity window.
Submit claim evidence, including installation photographs, chargepoint serial numbers and a site plan.
Installer claims the grant on your behalf once OZEV approves the paperwork.
A detail that catches applicants out: the voucher is valid for 180 days from issue, and if installation and claim submission slip past that window, the grant is forfeited. Build that deadline into your project plan from day one, particularly if civils work or a distribution board upgrade is needed.
Parking eligibility is the single most common reason applications fail. GOV.UK guidance is explicit that spaces must be demonstrably allocated to staff or fleet use at your premises, not simply nearby or informally available. If your car park is shared with other tenants or the public, get clarity on this before you apply, not after.
What standards and regulations apply to office EV charging?
Grant-funded office EV charging must meet a specific technical bar, and skipping this step is the fastest way to get a claim rejected.
Any chargepoint used in a WCS-funded installation must appear on the OZEV-approved model list and meet the minimum technical specification: compliance with BS EN 61851 (the core EV charging standard), a BS 62196 Type 2 connector, an appropriate ingress protection rating for outdoor use, and a minimum 3-year on-site warranty. Separately, all electrical installation work must comply with BS 7671 (the IET Wiring Regulations) and the associated IET Code of Practice for electric vehicle charging equipment installation.
Since 30 June 2022, most chargepoints sold in the UK also fall under The Electric Vehicles (Smart Charge Points) Regulations 2021, which mandate smart functionality: default off-peak charging hours, the ability to measure electricity use, and continued charging if the internet connection drops.
Before you commit to a design, check these site realities:
Single-phase vs three-phase supply, which determines how many chargers you can run at full speed simultaneously.
Whether your distribution board has spare capacity or needs upgrading.
Civils work required for cable routing between the board and parking bays.
Ingress protection rating needed if chargers sit in an exposed car park.
Pro Tip: Ask your installer for a load management proposal even if you’re only installing two or three sockets now. Retrofitting smart load balancing later is far more disruptive than designing it in from the start.
How much does office EV charging cost and how long does it take?
Costs vary by site, but four components consistently drive the budget: the chargepoint hardware itself, any distribution board or supply upgrade, civil works for cabling and groundwork, and installer labour. The WCS grant contributes up to 75% of purchase and installation costs, capped at a fixed amount per socket. So larger installations still carry a meaningful net cost once you exceed the per-socket cap.
A realistic sequence looks like this:
Feasibility survey and DNO capacity check: 1 to 2 weeks.
Grant application and voucher issue: typically a few weeks, dependent on evidence readiness.
Design, procurement and civils: 2 to 6 weeks, longer if a supply upgrade is needed.
Installation and commissioning: usually completed within days once civils are done, but must land inside the 180 day voucher window.
Two further funding levers are worth checking with your finance team. Sites with separately assessed chargepoints may qualify for business rates relief covering the 2026/27 to 2035/36 period, though this requires a distinct Valuation Office assessment. Capital allowances may also apply to qualifying plant and machinery expenditure, depending on your tax position.
Do employees pay tax on office EV charging?
Policy design determines whether charging feels like a genuine perk or a source of friction, so decide these questions before switch-on, not after.
You’ll need to choose between free charging, a flat session fee, or a per-kWh charge, and whether access requires staff registration or allows guest use for visitors and contractors. Parking allocation also needs a policy: first-come-first-served, priority booking, or fixed bays tied to specific vehicles.
Free or paid: decide whether electricity cost is absorbed or recovered via session fees.
Access control: registered users only, or open to visiting fleet and guests.
Parking rules: booking system versus open allocation.
Fault reporting: a clear route for staff to flag a broken connector or app issue.
On tax, HMRC guidance confirms that electricity provided for workplace charging can be exempt from taxable benefit, provided it’s available generally to employees rather than restricted to a select group. That exemption doesn’t extend automatically to arrangements structured through optional remuneration or salary sacrifice, so check the policy wording with your payroll or tax adviser before rolling it out.
Pro Tip: Keep your charging policy in writing and circulate it with your EV benefit or company car policy. A verbal “just plug in when you need to” arrangement is exactly what creates disputes over fairness once demand outstrips socket numbers.
Back-office software matters more than most facilities teams expect at the outset. You’ll want remote monitoring for fault alerts, user management for access control, payment reconciliation if you charge fees, and reporting for sustainability disclosures.
What should you ask installers before signing a contract?
A short procurement checklist saves weeks of back-and-forth once quotes start arriving:
Are you an OZEV-authorised installer able to process WCS voucher claims?
What warranty applies to hardware and installation workmanship, and for how long?
Does the proposed chargepoint appear on the current OZEV minimum technical specification list?
Who compiles claim evidence (photos, serial numbers, site plan) and within what timeframe?
What’s your approach to load management if we expand sockets later?
Is the charging platform portable if we switch providers in future?
What’s the realistic timeline for civils work and commissioning?
Who holds responsibility for ongoing maintenance once installed?
Do we need landlord consent or updated site insurance before work starts?
Who manages user billing and back-office reporting day-to-day?
For teams managing installer relationships or comparing multiple site visits, tools built for installer operations can help keep survey data, quotes and scheduling in one place.
How Swift Charging delivers office EV charging projects
Office EV charging projects typically include site survey, WCS grant support, authorised installation, load management design, and ongoing maintenance once chargers are live.
A defined set of deliverables at each stage typically includes a site feasibility report confirming electrical capacity and parking eligibility, evidence photography and documentation prepared for the WCS claim, a BS 7671 Electrical Installation Certificate on completion, and a 3-year on-site warranty on hardware as standard under the OZEV technical specification.
If you’re weighing up whether your car park qualifies or what a realistic budget looks like, requesting a feasibility survey is the most direct way to get site-specific numbers rather than working from national averages.
Swift Charging perspective: common mistakes and the right sequence
The three mistakes we see most often: skipping an early DNO capacity check (leading to design rework later), underestimating civils costs (cable routing across a car park is rarely cheap), and leaving parking allocation undefined until after chargers are live, which breeds disputes.
The fix is sequencing: feasibility and DNO check first, grant application second, design and civils third, installation last. Get in touch if you’d like project references from similar office installations.

FAQ
Can I charge my EV car at work?
Yes, if your employer has installed workplace chargepoints, and increasingly employers are adding these under the Workplace Charging Scheme to support staff with electric vehicles. If your workplace doesn’t yet have charging, raising it with facilities is the usual starting point, since the grant significantly reduces the employer’s installation cost.
What is the 80/20 rule for charging electric cars?
It’s a driver habit rather than a legal or grant requirement, but many workplace charging policies mention it as guidance for staff.
Is it free to charge an EV at Tesco?
Charging costs at supermarkets and other public locations vary by operator and site, and are set independently of workplace charging schemes, so there’s no single answer that applies everywhere. Office EV charging costs are a separate matter entirely, set by your employer’s own policy rather than a retailer.
Can employees claim for charging an electric car at home?
Employees can potentially claim mileage or reimbursement for business use, but the rules differ from workplace charging exemptions, and this typically depends on company policy and HMRC’s specific expense rules for electric vehicles. Where workplace charging is provided directly and available generally to staff, HMRC guidance confirms the electricity cost itself can be exempt from taxable benefit, which is a simpler position than reimbursing home charging.
