Residential properties occasionally require upgrades costing £500 to £3,000, whilst commercial premises with multiple high-power chargers may need substantial electrical infrastructure investment of £2,000 to £15,000+ depending on existing capacity and required expansion.
Commercial installations often require payment systems allowing businesses to charge employees, visitors, or the public for electricity usage. Contactless payment integration and networked management systems add £500 to £1,500 per charging point but enable businesses to recover electricity costs or generate revenue from charging services. Load balancing equipment prevents multiple chargers overwhelming electrical capacity by intelligently distributing available power, essential for commercial installations with three or more charging points.
Choosing the right charger for your needs
Selecting appropriate charging power ensures your installation meets requirements without unnecessary expense. Most Norfolk homeowners choose 7kW chargers, whilst businesses typically install 7kW to 22kW units depending on vehicle dwell times and charging requirements.
Comparing charger power ratings:
- 3.6kW (residential): ~15 miles range per hour, suits overnight home charging
- 7kW (residential/commercial): ~25-30 miles range per hour, most versatile option
- 22kW three-phase (primarily commercial): ~60+ miles range per hour, requires three-phase supply
- 50kW+ DC rapid (commercial only): 80% charge in 30 minutes, significant infrastructure investment
7kW chargers represent the most popular choice for Norfolk homes and many workplaces, delivering 25 to 30 miles of range per hour. This charging speed fully replenishes most vehicles within 4 to 6 hours, suitable for overnight residential charging or during typical working days at offices, retail premises, or hospitality venues where vehicles park for extended periods.
22kW three-phase chargers suit commercial premises where faster charging benefits staff or customers with limited parking duration. Hotels, restaurants, gyms, and shopping centres often install 22kW chargers allowing customers to meaningfully recharge during shorter visits. These units require three-phase electricity supplies and cost more to install but provide valuable competitive advantages for businesses attracting EV-driving customers.
