2021 MG ZS Exclusive EV Electric · HN21 ACU

As a pure electric vehicle, the MG ZS Exclusive EV benefits from zero VED (road tax) until April 2025 models reach the higher-rate threshold, though this 2021 example falls under the older £0 flat-rate rules. Benefit-in-Kind is minimal, and there is no congestion charge within the Congestion Charge zone. Insurance is typically group 21-25 depending on driver history, which is moderate for an EV family SUV.

Electric consumption for the ZS EV is officially around 3.7 miles per kWh (WLTP), giving a real-world range of roughly 160-190 miles from the 44.5 kWh battery. At an average home tariff of 24.5p/kWh, full-charge costs are around £10-11, equivalent to about 4-5p per mile. Public rapid charging will be considerably more expensive.

Estimated annual maintenance is low compared to a petrol equivalent — no oil changes, fewer brake wear items, and simpler drivetrain — but budget for tyre replacement (£400-£600 for a full set), annual service costs around £150-£250 at an independent EV specialist, and potential £100-£200 every few years for cabin and pollen filters. Estimated annual running cost: £900-£1,200 including electricity, insurance, and maintenance.

The MOT history shows tyre cracking and perishing as a recurring theme across all three tests. Inspect all four tyres closely — look for sidewall cracking (often caused by age rather than mileage), uneven wear patterns which could indicate suspension or alignment issues, and check the DOT date codes on the sidewalls. Tyres older than 5 years should be replaced regardless of tread depth, particularly on an EV with high torque output.

The 2024 and 2025 MOT tests both recorded rear brake disc pitting. Inspect the discs for deep pitting, ridges, or rust — although light surface corrosion is normal on EVs due to regenerative braking doing less work. Also check that the electronic parking brake releases cleanly, as MG EVs have had occasional issues with seized EPB mechanisms. Listen for any grinding or squealing on the test drive.

As this is an EV from 2021 with 43,170 miles, prioritise a battery State of Health (SoH) report. Anything below 85% would be concerning; below 80% would warrant significant price negotiation or walking away. Check the 12V auxiliary battery condition, inspect the charging port for damage or corrosion, and verify both AC and DC fast charging work as expected. Underbody inspection should look for corrosion on the chassis and any damage to the battery enclosure.
