MG ZS EV review (UK): Britain's outgoing budget EV — is a used one still worth buying in 2026?

Britain's best-selling affordable electric SUV is no longer on sale new. MG quietly withdrew the ZS EV from UK order books in July 2025 and replaced it with the MG S5 EV — a genuinely new car, not a facelift. If you are reading this because you are considering an MG ZS EV, you are now making a used-car decision.

That is not automatically bad. Used ZS EVs start from around £7,000 for early 2019 models and £9,000–£12,000 for the more capable 2021–2023 Long Range facelift cars. For someone with home charging, a modest budget, and patience with imperfect software, a used ZS EV Long Range in good condition can represent exceptional value. But you need to go in with eyes open — and most UK reviews were written when it was still on sale new. This guide is written for 2026, when the ZS EV is used stock and the S5 EV is the new alternative.

MG is owned by SAIC Motor (上汽集团) — Shanghai government state-owned, Fortune 500 top-100, one of China's largest car groups. This matters for a used-car buyer as much as a new one: the 7-year/80,000-mile warranty was a central selling point of the ZS EV, and whether it still has value depends on MG remaining a credible UK operation.

The good news: SAIC is an industrial giant, not a start-up. MG has had continuous UK dealer presence since 2011. The bad news — covered honestly in the reliability section below — is that MG Motor UK's after-sales service has attracted significant criticism. The warranty exists on paper; enforcing it has proved difficult for some owners. The 7-year/80,000-mile is a strong promise, but check how many miles (and years) remain on any used car you are considering, and factor in MG UK's Trustpilot track record before assuming it will be straightforward to claim.

Here is the decode point most UK reviews miss entirely. In China, the MG ZS EV was sold as the 名爵EZS (MG EZS) — and it is dead. Discontinued years ago. The car you are buying used in the UK today is a significantly updated version — the 2021 facelift with Long Range batteries, V2L, and iSMART infotainment — that China's market never received. The UK car is genuinely better than anything sold in China.

The flip side: because the EZS barely sold in China as an EV (most Chinese ZS platform data is from the petrol version), the Chinese owner intelligence is thin. The 汽车之家 (Autohome) score of 4.52/5 covers only 208 reviews across all variants, overwhelmingly petrol. The 懂车帝 (Dongchedi) score of 3.58/5 is also petrol-dominant. The common EV-specific complaints from Chinese owners — infotainment freezing, winter range drop, creaks and rattles — do map to what UK owners report, but the structural quality concerns are harder to separate from the petrol ZS noise.

The practical upshot: go heavier on UK owner data (see reliability section) and lighter on Chinese platform data for this particular model.

The Long Range ZS EV (72.6 kWh / 68.3 kWh usable) claims 273 miles WLTP. Auto Express achieved 252 miles in mixed testing — 7% below WLTP, which is an honest result. Typical year-round mixed driving lands at 220–240 miles. In cold British winters at motorway speeds, expect 160–190 miles.

The bigger issue is DC rapid charging. The maximum charge rate is 94 kW — a figure that was reasonable in 2021 but looks weak in 2026, when many rivals can manage 130–150 kW and the replacement MG S5 EV does 139 kW. There is no battery thermal preconditioning, which means on a cold day the charging rate may be even lower than 94 kW. A 10–80% charge takes roughly 37–42 minutes at a compatible charger. For urban and suburban driving with home charging, this is a non-issue. For motorway road trips, it is a genuine limitation.

The Standard Range (51 kWh / 49 kWh usable) claims 198 miles WLTP — expect 150–175 miles in winter. It also charges at up to 50 kW DC maximum, which makes it a poor choice for anyone who regularly drives long distances.

The MG ZS EV's reliability reputation is genuinely mixed — and that matters more in 2026, when you are buying used and the car may be outside its original service plan.

**The survey data is sobering.** What Car?'s Reliability Survey placed the ZS EV 24th out of 27 electric SUVs (81.8% problem-free), with MG finishing last of 30 manufacturers surveyed. That is a hard number and should not be smoothed over.

**The individual owner experience is more varied.** Many owners report years of trouble-free use — the Reddit threads are full of 40,000–50,000 mile owners who have never had a major fault. The disconnect between survey and owner anecdote is real: the survey captures the full fleet, including early 2022 models with known 12V battery issues that have since been addressed in production.

**The confirmed fault pattern:** Infotainment freezing and rebooting is the single most consistent complaint across all sources — every UK review mentions it, most owners have experienced it. It is irritating but not dangerous. The blind spot monitoring crashing is a more serious concern: two UK owners in reviewed threads reported it cutting out while driving. The CCU (Combined Charging Unit) failure — quoted at £2,700 outside warranty — is a lower-frequency but expensive fault. The 12V auxiliary battery is a documented weak point on 2022 cars.

**The after-sales sting.** MG Motor UK holds a Trustpilot rating of 1.8/5. The complaints pattern is consistent: long repair waits (3+ weeks), no courtesy car provision, and — in multiple documented cases — MG UK refusing consumer rights claims on repeat faults. The warranty is real; getting MG to honour it on a difficult fault has proved harder than the headline suggests. This is not conjecture — it is a recurring pattern across independent reviews. Build it into your risk calculus.

The MG ZS EV's residual values are poor — consistently one of the worst in the electric SUV class. CAP HPI data puts depreciation at roughly 25% per year, leaving approximately 42% of value after three years. That puts it alongside older Nissan Leafs and Renault Zoes, well below mainstream rivals.

For new-car buyers who paid £30,000–£35,000, this has been painful. For used buyers in 2026, it is the opportunity. A 2022-registered ZS EV Long Range that left the showroom at £32,995 can be found for £9,000–£11,000 — that is 67–73% depreciation absorbed by the first owner. At those prices, the 7-year/80,000-mile warranty (verify how much remains), the 273-mile WLTP Long Range, V2L, and an SAIC-backed brand become genuinely compelling for someone with home charging.

The arrival of the MG S5 EV in spring 2025 accelerated the ZS EV's used price decline. Some dealers discounted remaining new ZS EV stock by up to 40% to clear inventory — this price discovery immediately compressed used values. The effect has largely washed through; prices have stabilised at the levels quoted above.

This is the genuine question in 2026. For new-car buyers, the answer is straightforward: buy the MG S5 EV. It starts from £28,995 — actually less than a new ZS EV was at its end — and it is a categorically better car: dedicated EV platform, 139 kW DC charging (vs 94 kW), 298 miles WLTP Long Range (vs 273), a substantially improved interior, and a fresh 5-star Euro NCAP rating tested under the current (2025) protocol. The infotainment still has some lag, but it is a genuine step forward.

For budget-conscious buyers with home charging, the used ZS EV Long Range at £9,000–£12,000 makes a strong case on pure numbers. The depreciation has already been absorbed. The 273-mile WLTP range is adequate for most UK driving patterns. V2L is on higher-trim models. And a 2022-registered car still has several years of the 7-year warranty remaining — verify the registration date carefully.

The caution: you are inheriting whatever service history and any incipient faults come with the car. The infotainment will almost certainly be imperfect. MG's after-sales service is not a strength. If the CCU or T-Box fails, you are looking at potentially significant repair costs. A pre-purchase inspection — specifically checking 12V battery health and infotainment behaviour — is not optional; it is the difference between a bargain and a headache.

The MG ZS EV is a car in an unusual position: mediocre when new (reliable enough, but compromised platform, dated software, poor after-sales), and genuinely compelling as a used buy at today's prices.

**Buy a used MG ZS EV Long Range if:** You have home charging. Your budget is £10,000–£12,000. You predominantly drive urban and suburban routes. You can live with imperfect infotainment. You are comfortable doing a proper pre-purchase inspection. You want a spacious electric family SUV with a credible warranty backing and don't want to pay £30,000-plus for the S5 EV.

**Don't buy a used ZS EV if:** You regularly drive motorway distances and want fast charging stops. You want the latest safety ratings. You have a budget that stretches to the MG S5 EV. You need reliable after-sales support and can't tolerate delays.

**Buy the MG S5 EV instead if:** You are buying new and budget allows. It is a categorically better car — proper EV platform, modern charging, current safety ratings, improved interior — and it starts at the same price as a new ZS EV did when it was selling.
