Retail EV charging is going through a step change. Traditional petrol forecourts are adding DC rapid chargers. Supermarkets and shopping centres are installing AC chargers for customers. Dedicated EV charging hubs are emerging on strategic routes. For retail operators, planning these upgrades well is the difference between a profitable new revenue stream and a capital drain.
This guide covers how to plan a retail EV charging upgrade.
The Retail Use Case
Retail EV charging differs from workplace and destination charging in three important ways.
One. Dwell times are short. Petrol forecourt visits are typically 10-20 minutes. Supermarket shops are 30-60 minutes. Shopping centre visits are 90 minutes to 3 hours.
Two. Users are deliberately interrupting their journey to charge, so speed is important.
Three. Revenue is a primary goal. Unlike workplace charging (staff benefit) or residential charging (resident amenity), retail chargers are expected to generate income and contribute to site profitability.
This combination points to different charger mixes and operating models than other use cases.
Petrol Forecourt Upgrades
Petrol forecourts are the most visible retail charging segment. Typical patterns:
2-6 DC rapid chargers, usually 150kW or 350kW.
Sited adjacent to or replacing petrol pumps.
Paired with shop, coffee, and food amenities to capture dwell time.
Clear signage and marketing to attract EV drivers.
The challenge is that EV charging dwell is 10-30 minutes, much longer than the 3-5 minutes for a petrol fill. Forecourts that simply replace pumps with chargers find customer flow doesn’t work. Successful retrofits redesign the site to provide something to do during the charge: better coffee, bigger shop, outdoor seating, or children’s play areas.
Supermarket EV Charging
Supermarkets are a natural fit for 50kW DC rapid chargers.
Typical shop duration: 45-60 minutes.
A 50kW charger adds 100-150 miles during that time.
Customers welcome the convenience and are willing to pay a small premium.
A typical supermarket installation is 4-6 DC rapid chargers in dedicated bays, supplemented by 4-8 AC fast chargers for longer-stay customers.
Revenue per charger on busy supermarket sites can be £15,000 to £35,000 per year, depending on utilisation and pricing.
Shopping Centre Charging
Shopping centres typically have longer dwell times than supermarkets.
Typical visit: 90 minutes to 3 hours.
22kW AC is often sufficient.
Higher charger density supports weekend peak demand.
Charger count typically 5 to 15 per cent of parking spaces on high-EV-penetration sites.
Shopping centre charging revenue per charger is usually lower than supermarket DC, but the lower equipment and installation cost compensates.
Dedicated Charging Hubs
A new category: dedicated EV charging hubs on major routes, often associated with drive-through coffee, fast food, or short-stay retail.
Typical pattern: 6-12 DC rapid chargers, usually 150-350kW, with a coffee or food offering designed for a 20-30 minute stop.
Examples: Tesla Supercharger stations, Gridserve Electric Forecourts, InstaVolt sites.
These are greenfield developments rather than retrofits of existing retail. Cost is higher but customer experience is purpose-designed for EV drivers.
The Grid Connection
For any multi-charger DC installation, the grid connection is the dominant cost and programme item.
A 6-charger site with 4 x 150kW and 2 x 350kW DC has a peak demand of 1,300 kVA. Delivering that requires:
A customer substation.
Protection and metering equipment.
Grid agreement with the DNO.
Typical timeline: 4 to 9 months.
Typical cost: £80,000 to £250,000. See the full EV installation cost breakdown for how this compares to other site types.
Smart load management can reduce the peak demand but not below the largest single charger’s rating. A site with a 350kW charger needs at least 350kW of grid capacity.
Customer Experience Design
EV charging customers have specific expectations:
Clean, lit, safe charging bays.
Clear wayfinding and pricing.
Working payment systems, preferably contactless.
Shelter from weather.
Something to do during the 20-30 minute charge.
Good mobile signal for streaming or work.
Customer toilets and facilities.
Sites that get these right see 2-3x the utilisation of sites that don’t.
Revenue Models
Retail EV charging revenue models vary.
Pay per kWh is standard for most retail charging. Typical UK pricing in 2026: £0.50-£0.85 per kWh for DC rapid, £0.40-£0.70 for AC fast.
Pay per session for shorter stays, fixed fee regardless of energy.
Tiered pricing with member discounts for regular users.
Free charging with minimum spend in the retail outlet. Makes sense when the retail margin more than compensates for the electricity cost.
Time-of-use pricing is increasingly used to manage peak demand.
Revenue per charger varies enormously by site. Prime motorway sites generate £40,000+ per charger per year. Quiet suburban retail might generate £5,000-£12,000 per charger per year.
Payment Technology
UK regulations now require contactless payment on all new public chargers above 8kW. Key technology choices:
Contactless card reader on every charger.
Smartphone app as an alternative.
Roaming integration (letting users from other CPO networks pay through their home provider).
RFID card option for fleet customers.
The goal is zero friction: a driver with any payment method can charge immediately.
Planning Permission
Most EV charger installations at existing retail sites do not require planning permission. Exceptions include:
Significant structural additions (large canopies, new buildings).
Sites in conservation areas.
Listed buildings.
Local authority areas with specific EV charging policies.
Check with the local planning authority before starting design.
Typical Project Timeline
A retail EV charging project typically runs:
Feasibility and site assessment: 4-8 weeks.
Grid connection enquiry and offer: 6-12 weeks.
Planning approval (if needed): 8-16 weeks.
Detailed design: 6-10 weeks.
Equipment procurement: 8-16 weeks.
Civils: 3-8 weeks.
Installation and commissioning: 2-4 weeks.
Total: 30-50 weeks from start to live chargers, with grid connection usually the critical path. Our multi-charger planning roadmap sets out each stage in detail.
The Bottom Line
Retail EV charging is a real growth opportunity, but it is capital-intensive and operationally demanding. The sites that succeed have the right charger mix for their dwell time, adequate grid capacity, well-designed customer experience, and an operating model that generates revenue. The sites that struggle are the ones that treat chargers as a bolt-on amenity rather than a core part of the retail proposition. EV drivers choose where to charge, and they remember which sites work well. Design for their experience, and the revenue follows.
