Is the BYD Atto 3 reliable?

The BYD Atto 3 scores 74/100 on Forecourt's MOT-based reliability measure. That is computed from 12,047 real DVSA MOT test results.

How much does a used BYD Atto 3 cost?

A 2023 BYD Atto 3 with around 36,402 miles is worth roughly £16,950 today (typical range £14,300–£19,650). Dealer forecourt prices sit higher and part-exchange offers lower; newer or lower-mileage examples cost more.

How quickly does the BYD Atto 3 depreciate?

A new BYD Atto 3 typically loses about 54% of its value over the first three years, then depreciates more slowly. Buying at three to five years old avoids the steepest part of the curve.

What insurance group is the BYD Atto 3?

The BYD Atto 3 sits in insurance group 25 of 50 — the middle of the scale. Exact premiums depend on the trim (some versions sit a few groups higher or lower), your age, postcode and no-claims history.

What goes wrong on a used BYD Atto 3?

The most common age-related issues we track for the BYD Atto 3 are: suspension (typically around 60k-100k miles, £150-£450 to put right); tyres & wheels (typically around 60k-100k miles, £80-£500 to put right); seat belts & restraints (typically around under 30k miles, £80-£250 to put right). A full service history and a recent MOT with no advisories are the best protection.

What does the BYD Atto 3 cost to run?

Expect around 3.6 miles per kWh on the Design, £200 a year in road tax, about £185 for a standard annual service. The full cost-of-ownership table above breaks this down per year and per mile for the exact year and mileage you choose.

Is the BYD Atto 3 ULEZ compliant?

The BYD Atto 3 is pure-electric, so it is exempt from the London ULEZ charge and every other UK clean-air zone, whatever the registration year.

How many BYD Atto 3s are on UK roads?

About 9,625 BYD Atto 3s are currently taxed and on the road in the UK, from DfT vehicle-licensing data.

BYD Atto 3

The BYD Atto 3 is the Chinese giant's breakthrough UK electric family SUV - the car that introduced BYD to British buyers, built on its safety-focused Blade battery technology. Roomy, well-equipped and keenly priced, with a quirky, design-led cabin and a rotating central screen. Range and charging are competitive rather than class-leading, but as a value-led, well-warrantied electric SUV from the world's biggest EV maker, it's an increasingly common and sensible choice.

How these figures are sourced — the valuation is anchored to a researched used-market price for this model (AutoTrader median, 2023 at 30k miles). Reliability, mileage and variant data are real DVSA MOT records. Dimensions, tyre sizes and costs, servicing figures and the insurance group are segment-level estimates rather than sourced per car, and are being replaced model by model.

Forecourt score

Value 8 · Reliability 40 · catalogue percentiles

The BYD Atto 3 loses value faster than most cars. Its MOT-based reliability is good — an MOT score of 74/100. On three-year value retention it ranks better than 8% of models.

The Forecourt score blends how this car ranks against the catalogue on value retention, reliability and insurance cost (weighted 40/40/20) — the from-new ownership picture. Higher is better; running cost is not yet folded in.

Safety rating

Euro NCAP's independent crash-test rating for the BYD Atto 3, from its 2022 assessment.

5/5

TEST YEAR2022

Current rating · valid to 2028

The passenger compartment of the ATTO 3 remained stable in the frontal offset test.

Independent crash-test data from Euro NCAP. Star ratings reflect the test protocol of the year shown — newer protocols are stricter, so a 5-star from 2024 represents a higher bar than a 5-star from 2014. Euro NCAP ratings run for six years from publication; a lapsed rating means the protocol has moved on, not that the car performs any worse than it did on test.

What fails at the first MOT

Reliability

74/ 100

Good

First-MOT pass rate and defect rate for cars registered 2020 onward (187 first tests), with cohort survival — low confidence.

MOT outlook

Insufficient MOT history at this car's reference age — too few tests to compute a reliable percentile.

Things owners say

01The Blade battery (lithium-iron-phosphate) is robust and tolerant of regular full charges - a genuine plus.
02Range and charging speed are mid-pack - fine for most, but plan longer trips around real-world figures.
03Quirky cabin design and a strong warranty; BYD's UK dealer network is newer, so check local support.

Safety recalls

Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the BYD Atto 3, or your exact vehicle, has any outstanding recalls on the official DVSA service.

Check on GOV.UK

Opens the Driver & Vehicle Standards Agency recall checker. Choose the make, model and year of manufacture — no registration needed.

Theft risk

A general indicator from UK 2025 theft data and this car’s characteristics — not a prediction for any one vehicle.

Whole-car theft

Higher

Desirable SUVs like this are relay-theft targets — keyless entry can be exploited from the driveway in under a minute.

Parts theft

Lower

As an electric car it has no catalytic converter, so the most common parts-theft vector doesn't apply.

Worth doing

Keep keys in a Faraday pouch and away from the front door to block relay attacks.
A visible steering lock is a cheap, strong deterrent on a frequently-targeted car.

Clean-air zones

Whether driving a BYD Atto 3 into a UK clean-air zone will cost you anything. Rules use the same Euro standard across most zones — petrol from 2006 and diesel from 2015 onwards are exempt; pure electric is always exempt.

Charging zones for cars

City	Area	Daily charge	Likely outcome
London	All of Greater London (within the M25)	£12.50	Likely exempt Battery-electric — exempt everywhere.
