EV charging infrastructure for UK businesses: costs, grid capacity and funding
Most businesses budget for chargers and get caught by everything behind them. Civils, cabling, protection and the supply upgrade routinely account for more of the bill than the hardware. This guide covers the real cost shape of a commercial charging installation and how it is normally funded.

The short version
- Hardware is often the smaller half of a charging project. Groundworks, cabling and switchgear usually cost more.
- Available capacity at the site decides the project. A DNO supply upgrade can add months and a significant five or six figure sum.
- Load management or an on-site battery can avoid a supply upgrade entirely on some sites.
- The installed scope, including civils and commissioning, can generally sit inside one asset finance facility.
- The Workplace Charging Scheme pays up to 75% of costs, capped at £500 per socket for installations completed from 1 April 2026, until 31 March 2027.
What a commercial charging installation actually costs
There is no single price for a charge point because the same unit costs very different amounts to install depending on how far it sits from the incoming supply and what is under the ground between the two. The ranges below are the fully installed shape we see across UK quotes.
Figures on this page are indicative ranges drawn from UK market pricing we see across quotes and funder appetite. They are illustrations, not quotations, and every project prices on its own scope, site and credit profile.
| Charger type | Typical installed cost per unit | Common use |
|---|---|---|
| 7 to 22 kW AC, wall or post | £1,500 to £4,500 | Workplace car parks, staff and visitor charging |
| 22 kW AC with groundworks and long cable runs | £3,500 to £8,000 | Larger car parks, split bays, retrofit sites |
| 50 to 75 kW DC rapid | £25,000 to £50,000 | Fleet turnaround, customer dwell sites |
| 150 kW plus DC ultra rapid | £60,000 to £120,000 | HGV and van depots, public charging hubs |
| Site supply upgrade (DNO) | £10,000 to £250,000 plus | Where existing capacity cannot carry the load |
Grid capacity is the decision, not the chargers
Before anything is specified, the question is how much spare capacity the site already has. A unit with a 200 kVA supply running at 120 kVA on a busy afternoon cannot simply add four 50 kW rapids. The options are then a supply upgrade through the DNO, or managing the load so the existing supply is never exceeded.
Load management software staggers and throttles charging across the bays. On a depot where vehicles sit overnight, that is often enough on its own. Where turnaround is fast and the peak is unavoidable, an on-site battery can shave the peak so the site draws steadily rather than in spikes. Both routes are usually cheaper and considerably faster than a reinforcement job.
- Pull twelve months of half hourly data before specifying anything.
- Ask the DNO for a budget estimate early. The answer shapes the whole design.
- Price load management and a battery alongside the upgrade, not after it is quoted.
- Lay ducting for future bays while the ground is already open.
How the installation is funded
Charging infrastructure is funded the same way as other energy plant, on hire purchase or a finance lease over three to seven years. The useful part is that the facility can normally cover the installed project rather than only the hardware, provided the scope is itemised properly.
Where a project includes a DNO charge, that element usually sits outside the facility because it buys a connection rather than an asset. It is still worth raising early, because it changes the cash profile of the first month.
- Normally fundable: chargers, cabling, containment, switchgear, groundworks, bollards, signage, commissioning and back office hardware.
- Assessed case by case: extensive civils and surfacing, since these can read as land improvement.
- Usually outside the facility: DNO connection charges, planning fees and ongoing software subscriptions.
Grants and allowances
The Workplace Charging Scheme has been extended for a final year to 31 March 2027. It covers up to 75% of the cost of buying and installing chargepoints, capped at £500 per socket and 40 sockets per applicant. Treat it as a reduction to a project you would do anyway rather than the reason for doing it, and see our Workplace Charging Scheme guide for how it sits alongside finance.
Separately, charging equipment is plant and can attract capital allowances. The treatment depends on the funding structure you choose, so it is worth a short conversation with your accountant before the paperwork is signed rather than after.

FAQs
Common questions
The questions that come up most often on this subject.
How much does it cost to install an EV charger for a business in the UK?
Indicatively, £1,500 to £4,500 installed for a 7 to 22 kW workplace unit, £25,000 to £50,000 for a 50 to 75 kW rapid, and £60,000 upwards for ultra rapid. Distance from the incoming supply, ground conditions and available capacity move these figures more than the choice of charger.
Why is the installation more expensive than the charger?
Because most of the work is not the unit. Trenching, ducting, cabling, protection, bollards, surfacing reinstatement and commissioning all scale with distance and ground conditions. On a long run across a yard, the civils can be several times the hardware cost.
Do I need a grid connection upgrade to install rapid chargers?
Only if your existing capacity cannot carry the new load at peak. Check the half hourly data first. Load management, staggered charging or an on-site battery frequently avoid an upgrade, and both are quicker and cheaper than DNO reinforcement.
Can EV charging installation costs be financed?
Yes. Chargers, cabling, groundworks, switchgear and commissioning can generally sit inside one hire purchase or lease facility. DNO connection charges usually sit outside it, because they buy a connection rather than an asset.
How long does a commercial EV charging installation take?
Where capacity already exists, a workplace installation is typically a matter of weeks once the design is agreed. Where a supply upgrade is needed, the DNO timeline governs everything and can run to many months, so it should be started before the hardware is ordered.
