Frequently asked questions
How much does a Kia EV6 cost to run per mile in the UK?
At a standard UK home electricity rate of 26.1p/kWh (the Ofgem price cap unit rate for July–September 2026) and a real-world efficiency of 3.8 miles/kWh, the Kia EV6 costs approximately 6.9p per mile when charging at home. On a dedicated overnight EV tariff (around 7p/kWh) this falls to just 1.8p per mile. Relying entirely on public rapid charging — which averaged 79p/kWh in mid-2026 — raises the cost to 20.8p per mile.
Is the Kia EV6 cheaper to run than the Kia Sportage?
Yes, for most UK drivers who can charge at home. The Kia Sportage costs approximately 16.6p per mile in petrol at current UK prices. At home on a standard tariff, the Kia EV6 costs 6.9p per mile — a saving of 9.7p per mile. At 10,000 miles per year with 80% home charging, the Kia EV6 saves around £696 per year in fuel costs.
How long to break even switching from a Kia Sportage to a Kia EV6?
Based on an estimated price premium of £5,000 for the Kia EV6 over the Kia Sportage, and annual fuel savings of approximately £696 at 10,000 miles per year (80% home charging), the break-even point is around 7.2 years. Drivers covering more miles will reach break-even sooner — at 15,000 miles per year the saving is proportionally larger.
What if I can't charge the Kia EV6 at home?
Without home charging, the economics change significantly. Relying on public rapid charging — which averaged 79p/kWh in mid-2026, up sharply from a couple of years ago — puts the Kia EV6 at 20.8p per mile — higher than the Kia Sportage at 16.6p per mile. EV running cost savings are almost entirely dependent on home charging access. Drivers without off-street parking should factor this in carefully.
