The Workplace Charging Scheme (WCS) is the UK government's main subsidy for businesses, charities, and public sector bodies installing EV chargers for staff and fleet use. From 1 April 2026 the grant value increased from £350 to £500 per socket (per gov.uk guidance), capped at 40 sockets per applicant. For a typical small business adding 4 chargers, that's £2,000 toward installation costs. This guide walks employers through the full application process, eligibility checks, OZEV-approved installer requirements, and the tax treatment.
The 2026 facts
- Grant value: £500 per socket (up from £350 from 1 April 2026)
- Coverage: Up to 75% of the cost of purchasing and installing chargepoints
- Cap: 40 sockets per applicant (lifetime cap, not annual)
- Scheme duration: Confirmed until 31 March 2027
- Administrator: Office for Zero Emission Vehicles (OZEV), part of the Department for Transport
- Application route: Via OZEV-approved installer (NOT direct from gov.uk)
Who qualifies
Eligible applicants include:
- Limited companies (Ltd, PLC)
- Partnerships and LLPs
- Sole traders (registered as a business)
- Charities and not-for-profits
- Public sector bodies (local authorities, NHS trusts, education institutions)
- Other organisations operating in the UK
Required conditions:
- You must have off-street parking dedicated to staff or fleet use (private parking)
- You must be the owner of the parking area or have written permission from the owner to install chargers
- The chargers must be for staff or fleet use — not primarily commercial pay-per-use sales to the public
- You must use an OZEV-approved installer
- You must install an OZEV-approved chargepoint model
- You must be VAT-registered or able to provide UK business registration details
Who doesn't qualify
- Private individuals (use the residential OZEV grant streams instead)
- Commercial EV charging operators selling pay-per-use as their primary purpose
- Properties without off-street parking
- Properties where you don't have permission to install
- If you've already used your 40-socket lifetime cap
Application process step-by-step
- Confirm eligibility. Review the above checklist. If unsure, contact your accountant or an OZEV-approved installer for clarification.
- Choose an OZEV-approved installer. Not all electricians are OZEV-approved. Check explicitly. We connect you with vetted OZEV-approved Cornwall installers via the quote form.
- Choose OZEV-approved chargepoints. Approved brands include Pod Point Commercial, Zappi, Easee, Ohme, Hypervolt, Wallbox Commander, and others. Tesla Wall Connector is NOT approved.
- Site survey. The installer assesses your DNO supply, parking layout, cable routes, and load-management needs.
- Installer drafts the WCS application. They submit on your behalf via the OZEV portal.
- OZEV approval. Typically 5-15 working days. The voucher is issued to the installer.
- Installation. Installer fits, commissions, and certifies the chargers.
- Invoice with grant pre-applied. You receive an invoice for the net cost; the installer claims the grant from OZEV after install.
- Compliance certification. You receive a Building Regs compliance certificate per Part P; keep this for the life of the installation.
What's actually covered
- Purchase of OZEV-approved smart chargepoint(s)
- Installation labour for standard cable run, mounting, and commissioning
- Load-management hardware where included by the installer's standard package
- Building Regs certification
What's NOT covered (paid separately):
- DNO supply upgrades (sometimes free from Western Power; sometimes paid separately)
- Major civil works (trenching across large car parks, ducting under tarmac, bollards)
- Site preparation (line marking, signage)
- Non-approved chargepoint models (e.g. Tesla Wall Connector)
- Cable runs significantly above the installer's standard package allowance
Real-world cost scenarios
| Workplace | Sockets | Pre-grant cost | WCS grant | Net cost |
|---|---|---|---|---|
| Small office | 2 | £2,800-£4,000 | £1,000 | £1,800-£3,000 |
| Medium office | 4 | £4,800-£7,500 | £2,000 | £2,800-£5,500 |
| Holiday park | 8 | £8,500-£12,000 | £4,000 | £4,500-£8,000 |
| Hotel | 10 | £10,000-£15,000 | £5,000 | £5,000-£10,000 |
| Fleet depot (22kW) | 15 | £18,000-£28,000 | £7,500 | £10,500-£20,500 |
Tax treatment
Three key things to know (always confirm with your accountant):
- Capital allowances: EV chargers qualify for First Year Allowance, currently 100% in the year of purchase (subject to ongoing budget confirmation). The WCS grant value is deducted from the qualifying expenditure.
- VAT: Fully recoverable for VAT-registered businesses on the qualifying installation cost.
- BIK (Benefit in Kind): Workplace EV charging used by employees is exempt from BIK per current HMRC guidance — i.e. free for staff with no tax implications for either employer or employee.
- Company-car BIK on EVs: Currently 2-3% in 2026 for full EVs, vs 25%+ for petrol/diesel — a huge tax advantage for company-car drivers using workplace charging.
Common application mistakes
- Wrong installer. Using a non-OZEV-approved electrician means no grant. Always confirm OZEV approval explicitly.
- Wrong charger model. Tesla Wall Connector or unapproved imports don't qualify. Stick to the OZEV-approved list.
- Insufficient permission documentation. If you don't own the parking land, written permission from the owner is mandatory before applying.
- Applying for chargers you've already installed. The application must be approved BEFORE installation.
- Confusing WCS with OZEV residential grants. These are separate streams with separate application portals. Use the right one.
Multi-site applications
If your business has multiple Cornwall sites (e.g. a chain of B&Bs or a fleet operation with multiple depots), the 40-socket cap applies to your business as a whole — not per site. Plan strategically:
- Prioritise sites where chargers will be most-used (lowest payback period)
- Stagger installations across the WCS window (April 2026 - March 2027) to spread cost
- Consider phased rollout if some sites might benefit from additional WCS-extending policy in 2027+
Beyond WCS — other grants and reliefs
- OZEV residential landlord grant — separate stream, £500/socket, for properties let to long-term residential tenants (not staff/fleet use).
- Local council grants — some councils (not Cornwall as of 2026) offer additional commercial EV-charging support. Check Cornwall Council website for current programmes.
- Section 106 / planning conditions — new commercial developments may have EV-charging requirements embedded in planning permission. Part S applies to new builds.
