Frequently asked questions
How much does a Mercedes EQA 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 3.4 miles/kWh, the Mercedes EQA costs approximately 7.7p per mile when charging at home. On a dedicated overnight EV tariff (around 7p/kWh) this falls to just 2.1p per mile. Relying entirely on public rapid charging — which averaged 79p/kWh in mid-2026 — raises the cost to 23.2p per mile.
Is the Mercedes EQA cheaper to run than the Mercedes C-Class?
Yes, for most UK drivers who can charge at home. The Mercedes C-Class costs approximately 18.4p per mile in petrol at current UK prices. At home on a standard tariff, the Mercedes EQA costs 7.7p per mile — a saving of 10.7p per mile. At 10,000 miles per year with 80% home charging, the Mercedes EQA saves around £758 per year in fuel costs.
How long to break even switching from a Mercedes C-Class to a Mercedes EQA?
Based on an estimated price premium of £2,000 for the Mercedes EQA over the Mercedes C-Class, and annual fuel savings of approximately £758 at 10,000 miles per year (80% home charging), the break-even point is around 2.6 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 Mercedes EQA 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 Mercedes EQA at 23.2p per mile — higher than the Mercedes C-Class at 18.4p per mile. EV running cost savings are almost entirely dependent on home charging access. Drivers without off-street parking should factor this in carefully.
