EV Charging Cost Guide
Home Charging Costs
- Off-peak tariffs: 7-15p per kWh
- Standard tariffs: 25-35p per kWh
- Economy 7: Cheaper overnight rates
- Smart tariffs: Variable pricing based on demand
- Installation: £800-£1,500 for home charger
Public Charging Costs
- Slow charging (7kW): 25-40p per kWh
- Fast charging (22kW): 30-50p per kWh
- Rapid charging (50kW): 45-65p per kWh
- Ultra-rapid (150kW+): 60-85p per kWh
- Network membership: Often reduces costs
Cost-Saving Tips
- Charge at home during off-peak hours
- Use workplace charging when available
- Join charging network memberships
- Plan routes around cheaper charging points
- Consider time-of-use electricity tariffs

Charging Cost Comparison
| Charging Method | Power (kW) | Cost Range (p/kWh) | Time to 80% | Best For |
|---|---|---|---|---|
| Home (3-pin plug) | 2.3 | 25-35 | 24+ hours | Emergency charging |
| Home wallbox | 7 | 7-35 | 8-12 hours | Overnight charging |
| Public slow | 7-22 | 25-50 | 3-8 hours | Long stops |
| Public rapid | 50 | 45-65 | 45-90 mins | Top-up charging |
| Ultra-rapid | 150+ | 60-85 | 20-40 mins | Long-distance travel |
Off-Peak Charging
Take advantage of Economy 7 or smart tariffs to charge when electricity is cheapest, typically between 11 PM and 7 AM.
Charging Apps
Use apps like Zap-Map, PlugShare, or network-specific apps to find the cheapest charging options near you.
Battery Health
Avoid charging to 100% regularly and don’t let the battery drop below 20% to maintain optimal battery life.
Government Grants
Check for available grants like the EV Chargepoint Grant for home installations to reduce upfront costs.
Frequently Asked Questions
Charging costs vary significantly depending on location and method. Home charging typically costs 7-35p per kWh, while public charging ranges from 25p to 85p per kWh. For a typical 64kWh battery, a full charge costs £4.50-£22 at home or £16-£54 at public chargers.
Yes, home charging is significantly cheaper than public charging. With off-peak tariffs, home charging can cost as little as 7p per kWh, compared to 60-85p per kWh at ultra-rapid public chargers. However, public charging offers convenience and speed for longer journeys.
Key factors include: electricity tariff rates, charging speed (slower is usually cheaper), time of day, location (home vs public), charging network membership, battery capacity, and current charge level. Weather conditions can also affect charging efficiency.
To minimise costs: charge at home during off-peak hours, join charging network memberships, use workplace charging when available, plan routes around cheaper charging points, consider time-of-use tariffs, and avoid rapid charging unless necessary for long trips.
While not essential, a smart meter enables access to time-of-use tariffs that can significantly reduce charging costs. Smart meters allow you to take advantage of Economy 7, smart tariffs, and real-time pricing that can make overnight charging much cheaper.
Rapid charging (50kW) typically costs 45-65p per kWh, while ultra-rapid charging (150kW+) costs 60-85p per kWh. The higher cost reflects the convenience of faster charging speeds, which can add 100+ miles of range in 20-30 minutes.
