A common question from business decision makers when it comes to EV charging remains: How long does it take to turn a profit? The answer depends on multiple factors, including installation costs, revenue streams, pricing models, and usage rates. In this blog, we’ll break down the key considerations and help businesses estimate the return on investment (ROI) of your project.
1. Understanding the Costs of EV Charging Installation
Before turning a profit, businesses must cover the initial investment and ongoing operational costs.
Upfront Costs
The total installation cost varies depending on the type of charger and site conditions:
- Slow (7kW) Chargers – £900 to £2,500 per unit
- Fast (22kW) Chargers – £2,500 to £5,000 per unit
- Rapid (50kW+) Chargers – £20,000 to £50,000 per unit
- Ultra Rapid (100kw+) – £50,000+ per unit
Additional costs include:
- Groundworks & electrical upgrades – £1,000 to £10,000+ depending on site complexity
- Grid connection fees – Can be significant for high-powered chargers
- Software & networking fees – £150 to £500 per charger per year
Ongoing Costs
- Electricity costs – Businesses typically pay between £0.20 – £0.35 per kWh depending on their energy contract.
- Maintenance & servicing – £200 to £1,000 per charger annually, depending on the model.
- Back-office software & transaction fees – Often a monthly cost as well as a small percentage of each charge session.
2. Revenue Streams: How Do You Make Money?
Businesses can generate revenue from EV chargers in multiple ways:
A. Pay-Per-Use Charging
The most common model involves drivers paying per kWh or per session:
- Typical public charging rates: £0.40 – £0.80 per kWh
- Profit margin: If electricity costs £0.20 per kWh, charging at £0.50 per kWh yields a £0.30 per kWh profit.
Example Calculation:
- A 22kW charger operating at 30% utilisation (around 8 hours/day) could sell 176 kWh daily.
- At a £0.30 per kWh profit, this equates to £52.80 daily, or £19,272 annually.
B. Subscriptions & Memberships
Some businesses offer discounted charging for staff or through subscriptions, creating steady income streams.
C. Parking Fees & Increased Footfall
- Retail locations can attract more customers by offering charging, leading to higher sales.
- Hotels and workplaces may bundle charging with parking fees.
D. Partnerships & Grants
- Government incentives, like OZEV workplace grants, reduce upfront costs.
- Partnering with charge point operators (CPOs) can shift maintenance costs while sharing revenue.
3. How Long Until You Break Even?
The break-even point depends on:
- Charger cost (capital expenditure)
- Usage rate (how frequently it’s used)
- Electricity pricing & profit margins
Example ROI Scenario: A 22kW Business Charger
- Installation cost: £5,000
- Electricity cost: £0.20/kWh
- Charge price: £0.50/kWh
- Average usage: 6 hours per day (132 kWh)
- Profit per kWh: £0.30
Annual revenue:
- 132 kWh/day × £0.30 profit = £39.60 per day
- £14,454 per year
Breakeven timeline:
- £5,000 investment ÷ £14,454/year = Approximately 4-6 months
For high-traffic areas (e.g., motorway service stations, retail parks), ROI can be achieved in under a year, while lower-traffic locations may take 2-5 years on average.
4. Factors That Influence Profitability
Boosting Utilisation Rates
- Location matters – High-footfall areas (shopping centres, workplaces, fleet hubs) see faster returns.
- Marketing & visibility – Listing chargers on platforms like Zap-Map & Google Maps increases usage.
Maximising Profit Margins
- Smart charging tariffs – Using off-peak energy rates can lower electricity costs.
- Dynamic pricing – Adjusting prices based on demand can optimise revenue.
Reducing Costs
- Leverage government grants – The Workplace Charging Scheme (WCS) provides up to £350 per socket for business chargers.
- Use solar & battery storage – Reducing grid reliance can cut long-term costs. But may increase upfront costs.
Is EV Charging a Profitable Investment?
For businesses, EV charging can be highly profitable, with break-even timelines ranging from 6 months to 5 years, depending on location, usage rates, and pricing strategy. By choosing the right charger, leveraging grants, and optimising operational costs, businesses can ensure long-term profitability while supporting the EV transition.
