2014 BYD E6 Electric · FJ64 OWP

Running costs are dominated by electricity consumption; assuming an average efficiency of 0.3 kWh per mile and a UK electricity price of around £0.30 per kWh, the annual mileage cost would be roughly £3,200 × 0.3 kWh × £0.30 ≈ £290 for 10,000 mi, but even with higher mileage the electricity expense stays well below £400 per year.

The vehicle is tax‑exempt (zero VED) as a zero‑emission electric car, and its insurance group is likely in the 30‑40 range, translating to an annual premium of approximately £400‑£600 depending on driver profile and location. Routine maintenance for an EV is lower than for a combustion engine, but tyre wear (due to the vehicle’s weight) and occasional wiper blade replacement remain the primary recurring expenses, typically costing £150‑£250 per year.

Combining electricity, insurance, tax and typical maintenance, the estimated annual running cost for this BYD E6 is roughly £800‑£1,000, which is competitive for a low‑mileage electric SUV of its era.

Begin with a detailed visual inspection of the tyres, paying close attention to the edge wear and nail damage highlighted in the MOT advisories; measure tread depth with a gauge and look for uneven wear patterns that could indicate suspension or alignment problems. Inspect the front and rear wiper blades for the cracked or defective condition noted in the 2021 and 2020 tests, and test their operation in wet conditions to confirm they clear the windscreen fully.

Check the condition of the windscreen and glass for any chips or cracks, especially around the area where the wiper blades operate, and verify that the registration plate is securely attached and legible, as a deteriorated plate was recorded in the 2024 MOT. Inspect the underbody and wheel arches for corrosion, particularly around the charging port and battery enclosure, and look for any signs of water ingress that could affect electrical components.

Finally, assess the battery health indirectly by reviewing any service records for battery coolant checks or inverter maintenance, and listen for abnormal noises from the electric motor or drivetrain during a test drive; also verify that all lights, brakes, and suspension components are functioning correctly, as these are common wear points on higher‑mileage electric SUVs.
