Frequently asked questions
How much does a BYD Dolphin 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 4 miles/kWh, the BYD Dolphin costs approximately 6.5p 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 19.8p per mile.
Is the BYD Dolphin cheaper to run than the Volkswagen Golf?
Yes, for most UK drivers who can charge at home. The Volkswagen Golf costs approximately 15.9p per mile in petrol at current UK prices. At home on a standard tariff, the BYD Dolphin costs 6.5p per mile — a saving of 9.3p per mile. At 10,000 miles per year with 80% home charging, the BYD Dolphin saves around £669 per year in fuel costs.
Is the BYD Dolphin more or less expensive to buy than the Volkswagen Golf?
The BYD Dolphin is actually cheaper to buy upfront than the Volkswagen Golf by approximately £1,000, meaning you save on both purchase price and running costs — there is no break-even calculation required.
What if I can't charge the BYD Dolphin 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 BYD Dolphin at 19.8p per mile — higher than the Volkswagen Golf at 15.9p per mile. EV running cost savings are almost entirely dependent on home charging access. Drivers without off-street parking should factor this in carefully.
