Home EV Charging vs Public Charging: The Real Cost Comparison

With more Sheffield residents making the switch to electric vehicles, one of the most common questions we get is: "Is it worth installing a home charger?"

The short answer is almost always yes. Here's why.

The Numbers Don't Lie

Let's compare the costs for a typical EV owner driving 10,000 miles per year:

Charging MethodCost per kWhAnnual Cost
Home (night rate)~7p£175
Home (standard)~24p£600
Public (slow)~40p£1,000
Public (rapid)~70p£1,750

Based on an EV efficiency of 3.5 miles per kWh

The Convenience Factor

Beyond cost, home charging offers:

  • Always start with a full battery – no more detours to charging stations
  • Charge overnight – take advantage of cheap off-peak electricity
  • No queuing – especially valuable as EV adoption increases
  • Better for battery health – slower charging is gentler on your battery

Installation Costs

A typical home EV charger installation in Sheffield costs between £800-1,200, which includes:

  • 7kW smart charger (Zappi, Ohme, or similar)
  • Full installation with all fixings
  • OZEV grant application (saving £350 where eligible)
  • Testing and certification

Most Sheffield residents break even on their installation within 12-18 months.

What About Flats and Rented Properties?

If you don't have a driveway, options include:

  • Workplace charging – increasingly common in Sheffield city centre
  • Lamp post chargers – Sheffield Council is expanding these
  • Communal parking solutions – we work with landlords and management companies

Solar Integration

If you have solar panels, a smart charger like the Zappi can automatically use surplus solar energy. One of our Dore customers charges almost entirely from solar during summer months.

Making the Decision

For most homeowners with off-street parking, a home charger is a no-brainer. The savings add up quickly, and the convenience is genuinely life-changing once you experience it.
