Commercial EV Charger Installation Cost in London: What Businesses Should Budget For

For London businesses exploring electric vehicle charging, the first question is often simple: what will it cost to install chargers on-site?

The reality is more nuanced. The price isn’t just about the charging unit itself. A small office with a handful of parking spaces may only need straightforward electrical work, while a hotel, fleet depot or busy car park could face additional cabling, groundwork and even upgrades to its electricity supply.

Understanding these factors early helps avoid surprises and ensures the system is designed to meet both today’s needs and tomorrow’s growth.

How Much Does Commercial EV Charger Installation Cost in London?

There isn’t a single fixed price. As a broad UK guide:

  • 7kW–22kW AC single-socket chargers: typically £900–£2,500 per unit
  • Dual-socket AC units: around £2,500–£5,000

These figures are indicative only. Costs vary depending on the equipment chosen, the site’s layout, and the scope of electrical work. Rapid DC chargers are significantly more expensive.

For a reliable figure, a professional site survey is essential before committing to a charger or installation plan.

What Drives the Cost of Commercial EV Charging?

1. Number and type of chargers

An office where cars remain parked for hours may suit standard AC charging. A fleet depot, on the other hand, may need faster turnaround with rapid charging.

The “biggest” charger isn’t always the best choice. The right specification depends on:

  • How long vehicles stay parked
  • How many need charging simultaneously
  • The site’s available electrical capacity

Installing multiple chargers together can reduce costs per unit, but savings depend heavily on site layout.

2. Existing electrical capacity

Every building already has its own electricity demand — lighting, heating, IT, machinery. Adding EV chargers without considering this can cause problems.

Load balancing can help distribute available power, but it isn’t a cure-all. A proper assessment of the existing supply is crucial before deciding whether upgrades are necessary.

3. Cabling and groundwork

The distance between the electrical supply and parking bays can make or break the budget.

  • Close bays = simpler cable runs
  • Large car parks = trenching, ducting, reinstatement, protective equipment

London sites often add complexity: restricted access, shared parking, or limited space for electrical equipment. Two businesses installing similar chargers can receive very different quotes simply due to site conditions.

4. Distribution Network Operator (DNO) upgrades

If the supply cannot support the planned system, a DNO upgrade or new connection may be required. Costs vary depending on the work and distance from the network.

Not every site needs this — but it’s a factor worth checking before budgeting.

Grants and Support: Workplace Charging Scheme (WCS)

The WCS can reduce upfront costs for eligible businesses.

  • Up to £500 per socket (covering 75% of eligible costs)
  • Maximum of 40 sockets per applicant
  • Available until 31 March 2027
Grant to provide support towards the costs of the purchase, installation and infrastructure of electric vehicle chargepoints at eligible places of work.

Applications must be approved before installation begins, and an authorised installer must be used. Full details are available on the Workplace Charging Scheme guidance page.

Should You Install All Chargers at Once?

Not always. Many businesses benefit from installing what they need now while preparing infrastructure for future expansion.

For example, a large car park might start with a handful of chargers but lay cable routes or plan capacity for more units later. This avoids disruption when demand grows.

The right approach depends on:

  • Current vehicle numbers
  • Expected EV adoption
  • Parking arrangements
  • Expansion costs

When comparing quotations, make sure each installer is pricing the same specification. Check what’s included: hardware, electrical work, cabling, groundwork, commissioning, software, and maintenance.

Confirm whether supply upgrades are factored in, and whether your business qualifies for WCS support.
