Why Chinese Electric Cars Save Buyers £7,500 but Could Cost Them Thousands at Resale

• Chinese brands such as BYD and MG are now undercutting comparable European and Korean electric cars by between £2,000 and £11,500, with the biggest gaps in the £26,000 to £42,000 price band.
• Chinese-badged electric cars have taken close to 16 percent of the UK new car market this year, overtaking established names including Toyota and Nissan.
• Early resale data shows some of these cars losing value faster than rivals, so the saving at purchase can shrink or disappear by the time you come to sell.

The Saving Is Real, but So Is the Catch

Buyers cross-shopping a new electric car this year are finding that Chinese brands are simply cheaper than the equivalent European, Korean or Japanese alternative, sometimes by thousands of pounds. The BYD Atto 3 lists at £34,490 against £41,995 for a Hyundai Ioniq 5 with comparable equipment, a saving of £7,500 for what buyers get is a broadly comparable family SUV with a longer battery warranty. Across the wider £26,000 to £42,000 band, where most family-sized electric cars sit, the gap between Chinese and established brands runs from £7,000 to £11,500 according to industry pricing comparisons. Smaller models show the same pattern: the BYD Dolphin Surf starts at £18,650, and MG’s own MG4 undercuts comparable Volkswagen, Hyundai and Kia electric hatchbacks by £2,000 to £5,000.

The scale of the shift is showing up in the sales figures. Chinese-owned brands now hold close to 16 percent of the UK new car market, comfortably ahead of long-established names such as Toyota and Nissan. In the first quarter of 2026, BYD and Chery Group registrations combined overtook Volkswagen for the first time. A large share of the UK new car market’s growth so far this year has come from just four Chinese brands.

Why the Cars Are So Much Cheaper

Unlike the European Union, which imposed extra tariffs on Chinese-built electric cars to protect domestic manufacturers, the UK has not followed suit, so Chinese brands can sell into Britain at closer to their true production cost. Combined with in-house battery and component manufacturing that keeps their build costs down, this lets brands including BYD, MG, Omoda, Jaecoo and GWM Ora price aggressively while still turning a profit, and pass a meaningful chunk of that saving straight to the buyer’s invoice.

Where the Money Can Come Back Off You

The catch shows up later, when it is time to sell. Depreciation data from the used electric car market suggests Chinese-brand models including MG, BYD and Ora are currently retaining only around 22 to 35 percent of their original value after three years, a steeper drop than the 25 to 35 percent typically lost by an equivalent Tesla over the same period. In practical terms, a Chinese electric car that saved you £7,500 against a European rival at purchase can end up losing several thousand pounds more in resale value over three years, eating into or wiping out that initial discount depending on the model and how long you keep it.

Part of the reason is simply age. Most Chinese brands have been selling electric cars in meaningful numbers in the UK for under three years, so there is not yet the eight to ten year ownership and resale dataset that exists for Toyota, Volkswagen or Nissan. Buyers and dealers price used cars partly on trust built up over a decade or more, and Chinese brands have not had the time to build that yet. MG is furthest ahead, having sold the MG4 and MG ZS in the UK from 2022 onward, which means used prices for those two models are starting to settle into predictable patterns. BYD, by its own market’s admission, sits roughly two years behind MG in that maturing process.

The Insurance Bill Can Erase Part of the Saving Too

Resale value is not the only place the upfront discount can leak away. Some UK insurers are quoting higher premiums for certain Chinese-brand electric models. Repair parts and approved bodyshops for newer brands remain thinner on the ground than for long-established manufacturers, and insurers also have less historical claims data to price the risk accurately. A car that is cheaper to buy but more expensive to insure and slower to repair after even a minor bump can narrow the gap in total running costs compared with an established rival, so it is worth getting a genuine insurance quote before you commit to a purchase rather than assuming the lower list price tells the whole story.

The One Number That Protects Your Resale Value

If you are comparing a Chinese electric car against a pricier established rival, the detail that counts most for resale is the battery warranty, and specifically whether it transfers to a second owner. MG backs its cars with a seven year, 80,000 mile warranty that carries over when the car is sold. BYD goes further with an eight year, 155,000 mile battery warranty that also transfers. A used MG4 or BYD Dolphin sold with several years of that cover still remaining is a materially lower risk purchase for the next buyer than the same car with the warranty expired, and buyers are willing to pay more for it. When you come to sell, check how many years and miles of warranty cover remain on your car and make sure any listing states it clearly. This single figure can be the difference between a strong resale price and a weak one.

Dealer network size is the other factor worth checking before you buy rather than after. MG has around 180 dealers across the UK, giving most buyers reasonable geographic coverage for servicing and warranty work. BYD has closer to 100, thinner coverage for a fleet that is growing quickly, and owners have reported longer waits for service appointments as a result. A car that is expensive or slow to get serviced tends to sell for less when the time comes, regardless of how competitive its original price was.

Which Buyers Come Out Ahead

None of this means Chinese electric cars are a bad buy. For drivers who plan to keep a car for its full useful life rather than sell it after three years, the depreciation gap counts for far less, and the upfront saving of several thousand pounds is money in your pocket from day one. Buyers who plan to sell within three to five years, or who lease through a PCP deal where the finance company absorbs the resale risk, are the ones most exposed to the depreciation gap and should weigh the smaller monthly saving against the size of that gap before signing. Checking warranty transferability, getting a real insurance quote and finding your nearest approved dealer before you buy, rather than after, is the difference between banking the saving and quietly losing it again. A short test of how far your nearest approved service centre is, and a call to ask about typical waiting times for a routine service, tells you more about the real cost of ownership than any brochure figure ever will.
