Commercial EV Charger Installation Cost UK (2025 Guide)
What commercial EV charger installation really costs in the UK in 2025 — hardware, civils, DNO fees and grants — with realistic ranges per charger type.
Installing commercial EV chargers in the UK in 2025 typically costs between £1,200 and £40,000+ per charger all-in, depending on charger speed, civils, electrical capacity and whether a DNO supply upgrade is required. This guide breaks down what you're really paying for — and where independent design can save 20–40% on a typical scheme.
Typical installed cost per charger (UK, 2025)
- 7kW socketed AC — £1,200–£2,500 per bay (workplace / multi-dwelling)
- 22kW AC — £2,000–£4,500 per bay
- 25–50kW DC — £12,000–£25,000 per unit
- 75–150kW DC rapid — £30,000–£60,000 per unit
- 180–350kW ultra-rapid — £55,000–£120,000+ per unit
These are installed ranges including hardware, basic civils, cable runs under ~30m, commissioning and back-office onboarding. They exclude DNO reinforcement, substations and major civils.
What drives the cost
1. Available electrical capacity
The single biggest variable. If your site already has spare capacity at the main LV panel, a 6-bay 22kW scheme can be commissioned without DNO involvement. If not, a DNO supply upgrade can add £15,000–£200,000+ and 6–18 months to the programme. Run a feasibility check in our free calculator before you commit to a charger count.
2. Civils and trenching
Trenching typically runs £150–£350 per linear metre across tarmac. Boring under live carriageway or root-protected zones can double that. Smart layout — chargers close to the existing supply, back-to-back bays sharing a trench — is usually the largest cost lever on a multi-bay scheme.
3. Charger hardware and back-office
OCPP-compliant 7kW units start around £550 ex-VAT; load-managed commercial-grade units cost £900–£1,800. DC units are dominated by hardware cost, not install. Avoid vendor lock-in: choose hardware that speaks open OCPP 1.6J or 2.0.1 so you can change CPO/back-office later without ripping out the estate.
4. Load management vs supply upgrade
Dynamic load management (DLM) is often a £2,000–£8,000 line item that avoids a £50,000+ DNO upgrade. On almost every workplace and multi-dwelling scheme we audit, the DLM-first design wins on both cashflow and time-to-energise.
Grants that reduce the bill
- Workplace Charging Scheme (WCS) — up to £350 per socket, max 40 sockets per applicant.
- EV Infrastructure Grant for Staff and Fleets — up to £15,000 per site for infrastructure works (SMEs).
- EV Chargepoint Grant for Landlords — up to £350 per socket on residential rental property.
- ORCS — Local-authority on-street residential funding.

How to budget realistically
- Establish available LV capacity (or get a DNO Form A back).
- Set a 5–10 year demand forecast — don't size for today only.
- Cost two scenarios: DLM-first vs supply upgrade.
- Apply grants before hardware selection — eligibility varies by socket type.
- Leave 10–15% contingency for civils surprises.
Common mistakes that inflate cost
- Letting a single CPO bundle hardware + install + back-office (no benchmark).
- Sizing chargers to peak demand rather than diversified demand.
- Ignoring half-hourly tariff impact — a poorly designed scheme can raise the building's red-band capacity charge.
- Skipping the DNO Form A and discovering a £75,000 reinforcement after the lease is signed.
