BYD Dolphin Surf review (UK): price, range, charging, verdict

The BYD Dolphin Surf is a four-seat electric city car that costs from £18,650 in November 2026, with 137 to 200 miles of WLTP range depending on the battery. It is roomy and generously equipped for the money, and the £21,950 Boost is the version to buy; it is not built for long motorway trips or for anyone who needs five seats.

The Dolphin Surf is BYD’s small city car, 3,990 mm long, and BYD began UK deliveries in June 2025. EV Compared has not driven it: this review rests on BYD’s published UK data, government and Euro NCAP figures, and the UK reviews named below.

Verdict: who should buy the BYD Dolphin Surf, and who should not?

Buy a Dolphin Surf if most of your driving is in town and the suburbs, you can charge at home, and you want a new electric car with a lot of equipment for around £20,000. The Boost gives 200 miles of WLTP range for £21,950, and charged off-peak at home it costs 1.4p a mile to run. Adaptive cruise control, a rotating 10.1-inch touchscreen, keyless entry and vehicle-to-load come on every version, and BYD backs the car with a six-year warranty and an eight-year battery warranty.

Do not buy one if you regularly carry five people: it has four seats. Skip it, too, if you drive long distances on the motorway every week, because the 85 kW peak charging speed and the testers’ motorway efficiency figures mean frequent, slowish stops. And if you enjoy driving, UK reviewers find the Renault 5 and others more polished on the road.

What is the BYD Dolphin Surf, and is it the same as the BYD Seagull?

The Dolphin Surf is the European name for the car BYD sells in China as the Seagull, according to The Car Expert; in some other markets it is called the Dolphin Mini. It is a small, front-wheel-drive electric hatchback with BYD’s LFP Blade Battery, offered in three UK trims: Active, Boost and Comfort.

It is not a shorter version of the BYD Dolphin. The Dolphin is a separate, larger hatchback; our BYD Dolphin review covers its price, range and charging. If you are weighing up the whole line-up, our guide to every BYD electric car on sale in the UK lists the prices side by side.

How much is the BYD Dolphin Surf, and what do the trims include?

The BYD Dolphin Surf costs £18,650 as the Active, £21,950 as the Boost and £23,950 as the Comfort, on BYD’s UK on-the-road prices in November 2026. The Active has the smaller 30 kWh battery; the Boost and Comfort share a 43.2 kWh battery, and the Comfort adds a more powerful motor.

Trim	Price (Nov 2026)	Usable battery	WLTP range	Power	0 to 62 mph	Price per mile of range
Active	£18,650	30 kWh	137 miles	65 kW	11.1 seconds	£136
Boost	£21,950	43.2 kWh	200 miles	65 kW	12.1 seconds	£110
Comfort	£23,950	43.2 kWh	193 miles	115 kW	9.1 seconds	£124

Price per mile of range is EV Compared’s own figure: list price divided by WLTP miles, as set out in our methodology.

According to BYD’s UK specification, the Active comes with 15-inch wheels, the 10.1-inch rotating touchscreen, adaptive cruise control, NFC keyless entry and start, a rear-view camera, rear parking sensors, air conditioning, vegan leather seats, LED daytime running lights and vehicle-to-load. The Boost adds 16-inch alloy wheels, electric adjustment for the front seats, rain-sensing wipers and electrically folding mirrors. The Comfort adds a 360-degree camera, LED headlights, heated front seats, wireless phone charging, rear privacy glass and footlights in the door mirrors.

No Dolphin Surf is on the government’s Electric Car Grant list, so there is no grant discount at the dealer. Discounts do exist: Carwow listed an average saving of £2,016 off the recommended price when it updated its review in September 2026.

Dolphin Surf Active, Boost or Comfort: which should you choose?

Choose the Boost unless your driving is almost all short town trips. For £3,300 more than the Active it adds 63 miles of WLTP range, faster 85 kW rapid charging and more kit, and at £110 of list price per mile of range it is the best value of the three on our sums. Electrifying.com’s tester also picked the Boost as the sweet spot.

The Active makes sense as a second car or a pure town runabout. Its 137-mile WLTP range covers a week of short commutes, and at £18,650 it has a lower list price than any rival in our comparison table below.

The Comfort is the one to pick if you want more performance or the heated seats and 360-degree camera. Its 115 kW motor cuts the 0 to 62 mph time to 9.1 seconds, against 12.1 seconds in the Boost, but it covers 7 fewer WLTP miles and costs £2,000 more. Auto Express also found that the Comfort’s extra power brings torque steer and wheelspin on wet roads.

What is the BYD Dolphin Surf’s range, WLTP versus real world?

The Dolphin Surf’s WLTP range is 137 miles for the Active, 200 miles for the Boost and 193 miles for the Comfort. In kilometres that is about 220 km, 322 km and 311 km. BYD also publishes a WLTP city figure, which rises to 203 miles for the Active, 305 miles for the Boost and 288 miles for the Comfort, because a small electric car uses least energy at low speeds.

On the official test the Boost manages 4.63 miles per kWh, the Active 4.57 and the Comfort 4.47; these are EV Compared’s figures, WLTP range divided by usable battery.

UK testers’ results show how much that depends on where you drive:

• Auto Express averaged 5.6 miles per kWh in a Comfort on suburban roads in warm weather, then 3.9 miles per kWh in its motorway-heavy range test. On our sums, that motorway figure means about 168 miles from the 43.2 kWh battery.
• Electrifying.com’s Comfort averaged 4.4 miles per kWh, mostly in slow town driving in warm weather, and its tester estimates 130 to 180 miles of real-world range from the larger battery.
• Auto Trader’s test returned 5.2 miles per kWh, which its reviewer estimates is about 150 miles from the 30 kWh Active.
• Carwow’s Comfort managed 4.4 miles per kWh in town and 4.0 miles per kWh in mixed driving.

Expect less in winter, when the battery is cold and the heater draws power; our explainer on why EVs charge more slowly in cold weather covers the effect on charging too.

How fast does the BYD Dolphin Surf charge?

Every Dolphin Surf charges from 10 to 80% in 30 minutes on a DC rapid charger, according to BYD, at up to 65 kW on the Active and 85 kW on the Boost and Comfort. At home all three take up to 11 kW on AC, and a full charge on a 7 kW wallbox takes about 4.3 hours for the Active and 6.2 hours for the Boost or Comfort, on our sums.

Where you charge	Active (30 kWh)	Boost and Comfort (43.2 kWh)
7 kW home wallbox, 0 to 100% (EV Compared)	About 4.3 hours	About 6.2 hours
11 kW AC, 0 to 100% (BYD)	About 3.5 hours	About 5 hours
DC rapid, 10 to 80% (BYD)	30 minutes at up to 65 kW	30 minutes at up to 85 kW
DC rapid, 30 to 80% (BYD)	25 minutes	22 minutes
Miles added in 10 minutes of rapid charging (EV Compared)	About 32 miles	About 47 (Boost), 45 (Comfort)
Full charge at home off-peak, 6.5p/kWh	£1.95	£2.81
Full charge at the price cap, 26.32p/kWh	£7.90	£11.37
Full charge on a public rapid charger, 82p/kWh	£24.60	£35.42

Our wallbox times use the slower of 7 kW and the car’s onboard charger, the miles added in 10 minutes assume 70% of the battery goes in during the 30-minute 10 to 80% charge, and the costs ignore charging losses. The 6.5p rate is Intelligent Octopus Go’s smart charging rate, 26.32p is Ofgem’s average Direct Debit unit rate from October to December 2026, and 82p is Zapmap’s October 2026 average for rapid and ultra-rapid chargers.

The peak speeds are modest. Electrifying.com lists slow charging among the car’s cons, and Auto Express notes that most UK home wallboxes run at 7.4 kW. With a small battery, though, a 30-minute stop adds enough for most town drivers, and the charging speed matters less than it would in a car you take on long trips.

Can you leave it charging overnight? Yes: both batteries fill on a 7 kW wallbox in a normal night. Intelligent Octopus Go’s 6.5p/kWh rate covers up to six hours of smart charging a day, and Octopus has an eligibility checker for individual cars. For choosing and installing a home charger, our partner site Best Chargers compares wallboxes and installation.

Without a driveway, a small battery is easier to top up on slower street chargers than a big one; our guide to ubitricity lamppost charging explains prices and how to pay.

What does the BYD Dolphin Surf cost to run?

Charged at home on a 6.5p/kWh off-peak tariff, the Dolphin Surf costs 1.4p a mile in Active or Boost form and 1.5p in the Comfort, on our sums from the WLTP efficiency figures. That is £112 to £116 over 8,000 miles.

How you charge	Active	Boost	Comfort
Home off-peak, 6.5p/kWh: pence per mile	1.4p	1.4p	1.5p
Home off-peak: cost over 8,000 miles	£114	£112	£116
Price cap rate, 26.32p/kWh: pence per mile	5.8p	5.7p	5.9p
Price cap rate: cost over 8,000 miles	£461	£455	£471
Public rapid, 82p/kWh: pence per mile	18.0p	17.7p	18.4p
Public rapid: cost over 8,000 miles	£1,436	£1,417	£1,468

The difference between charging at home off-peak and relying on rapid chargers is more than £1,300 over 8,000 miles. If you do use public chargers regularly, a roaming card such as Octopus Electroverse lets you pay across several networks from one account.

Insurance. Auto Express and Carwow both list the Active and Boost in insurance group 14A and the Comfort in group 19D.

Vehicle tax. Zero emission cars pay £10 in the first year and the standard rate of £200 a year after that, according to gov.uk. Every Dolphin Surf is far below the £50,000 list price at which electric cars pay the expensive car supplement.

Company car tax. Electric company cars are taxed on 4% of their list price in the 2026 to 2027 tax year, according to HMRC’s guidance, so the Surf’s low list price keeps the taxable benefit small.

How big is the boot, and how practical is the Dolphin Surf?

The Dolphin Surf has a 308-litre boot with the rear seats up and 1,037 litres with them folded, according to BYD. That is nearly double the 162 litres of the Honda Super-N and well ahead of the Fiat 500e’s 185 litres, though the five-seat Fiat Grande Panda, Nissan Micra and Renault 5 all offer more.

The car measures 3,990 mm long, 1,720 mm wide and 1,590 mm tall on a 2,500 mm wheelbase. It has four seats, not five. There are three ISOFIX points: two in the rear and one on the front passenger seat.

The long wheelbase is the Surf’s strength. Auto Express found four adults fit comfortably and judged its rear legroom better than in the Renault 5 and Citroen e-C3, calling the interior space “excellent” for a car this small. Electrifying.com found room for four adults, and Auto Trader found more rear space than most people would expect. The drawbacks: Auto Express found rear visibility poor and noted there is no rear wiper, and Carwow describes the boot as awkwardly shaped because it narrows towards the top.

Vehicle-to-load is standard, letting you power appliances from the battery at up to 3.3 kW, according to BYD.

What the testers say about the BYD Dolphin Surf

UK reviewers agree the Dolphin Surf is roomy and good value, and that it is less polished to drive than the best small electric cars. The summaries below are their findings, not EV Compared’s.

Auto Express rated the Dolphin Surf 4 out of 5 in June 2026, calling it “arguably the Chinese brand’s most convincing model yet”. Ellis Hyde and Steve Walker found that “the ride is smooth, and overall refinement is good for a car of this size”, though the suspension is noisy over bumps and harsh over serious potholes. They criticised weak regenerative braking with no one-pedal mode (“Even in the ‘high’ regen mode, it barely feels like you’re not slowing down”), steering that feels sticky around the centre and needs constant small corrections on straight roads, and a frustrating driver monitoring system, and concluded that the Citroen e-C3 and Renault 5 are more sophisticated to drive.

Electrifying.com’s Vicky Parrott called the cabin “a pleasant surprise”, with physical buttons for the essentials, and found the car “sprightly, not sporty” in town. She judged the ride “generally decent” but not refined enough for the worst bumps, the brake pedal “slightly spongy on first press” and the regenerative braking too mild. The review’s cons are slow charging and rivals that feel more grown-up.

Auto Trader gave it 3.5 out of 5 in June 2025. Mark Nichol found the soft suspension “smooths everything over” on rough town roads, but that “the body rolls a lot” in corners. He described the cabin as feeling “like stepping back into the early 2000s, but in a quite charming sort of way”, and rated reliability 3 out of 5 because there is little UK data on BYD yet.

Carwow’s review is the most critical. Mario Christou praises the “generous standard kit and spacious cabin” but finds the suspension stiff, so the car rattles and bounces in town, the braking inconsistent depending on the regeneration level, the plastics cheap in places and the car one that “isn’t as comfortable as its alternatives”. Carwow did find it fun on twisty roads in Sport mode.

The common threads: space, equipment and price impress; brakes, ride quality over bad roads and driving polish do not.

Is the BYD Dolphin Surf safe and reliable?

The Dolphin Surf has a five-star Euro NCAP rating, published on 8 September 2025, with 82% for adult occupants, 86% for child occupants, 76% for vulnerable road users and 77% for safety assist. Euro NCAP’s assessment marked it down for poor control of occupant movement in far-side impacts, marginal chest protection for the rear passenger in the full-width frontal test, poor pedestrian head protection around the windscreen pillars, reversing emergency braking that does not react to pedestrians behind the car, and marginal driver monitoring.

There is no long-term reliability record yet; the car has only been on UK roads since mid-2025. Auto Trader rates reliability 3 out of 5 for that reason, and Carwow notes BYD came 16th of 30 brands in the 2026 Driver Power survey. BYD’s answer is the warranty: six years or 150,000 km on the car, and eight years or 250,000 km on the Blade Battery, with BYD guaranteeing at least 70% state of health under a January 2026 extension that also covers existing owners.

For recalls, use the government’s vehicle recall checker, which searches by registration number or by make, model and year; it is the reliable way to check a specific Dolphin Surf, new or used, before you buy.

Which rivals should you compare with the BYD Dolphin Surf?

The closest rivals on price are the Honda Super-N and Fiat 500e just above the Active, and the Fiat Grande Panda, Nissan Micra, Renault 5 and Hyundai IONIQ 3 around the price of the Boost. The Surf has more space than the four-seat Honda and Fiat 500e, while the others seat five.

Car	List price (Nov 2026)	WLTP range	Peak DC charging	Boot	Seats
BYD Dolphin Surf Active 30kWh	£18,650	137 miles	65 kW	308 litres	4
Honda Super-N Advance	£18,995	128 miles	50 kW	162 litres	4
Fiat 500e Icon 70kW 24kWh	£20,995	118 miles	50 kW	185 litres	4
Fiat Grande Panda Pop 83kW 44kWh	£21,495	199 miles	100 kW	361 litres	5
Nissan Micra Engage 40kWh	£21,495	196 miles	80 kW	326 litres	5
Renault 5 E-Tech Evolution Urban Range 40kWh	£21,495	194 miles	80 kW	326 litres	5
BYD Dolphin Surf Boost 43.2kWh	£21,950	200 miles	85 kW	308 litres	4
Hyundai IONIQ 3 Advance 42kWh	£22,245	213 miles	Not published	441 litres	5
BYD Dolphin Surf Comfort 43.2kWh	£23,950	193 miles	85 kW	308 litres	4

On list price per mile of WLTP range, the Boost’s £110 matches the Nissan Micra and is close to the Renault 5’s £111 and the Grande Panda’s £108; the IONIQ 3 works out at £104. Charged at home off-peak, all of these cost between 1.3p and 1.5p a mile on our sums, so running costs will not separate them.

Hyundai IONIQ 3. The IONIQ 3 qualifies for the full £3,750 Electric Car Grant, and Hyundai prices the Advance 42kWh at £18,495 after it, less than the Dolphin Surf Active. Hyundai quotes up to 213 miles, a projected WLTP figure pending homologation, and its 441-litre boot is far bigger. If you want five seats and a bigger boot for Surf money, it is the strongest alternative here.

Renault 5 and Nissan Micra. Both have five seats, 80 kW charging and a 326-litre boot, and both 40 kWh versions are in the £1,500 band of the Electric Car Grant. Renault’s £21,495 price for the 5 Evolution already includes the grant. Auto Express rates the Renault 5 as the more sophisticated drive.

Fiat Grande Panda. The Grande Panda has the biggest boot here after the IONIQ 3, at 361 litres, with five seats and 100 kW charging, for £455 less than the Surf Boost. Like the Surf, it gets no grant.

Honda Super-N and Fiat 500e. These four-seat city cars cost a little more than the Active and go less far, with 50 kW charging and much smaller boots. The 500e is in the £3,750 grant band.

Should you buy a BYD Dolphin Surf?

Yes, if you want a new electric car for town and suburban driving, you can charge at home, and you value space and equipment over polish. The Boost is the pick: £21,950 buys 200 miles of WLTP range, room for four adults, adaptive cruise control and a six-year warranty, and off-peak home charging brings the running cost down to 1.4p a mile. The Active at £18,650 suits a second car or a driver who rarely leaves town.

No, if you need five seats, regularly drive long distances on the motorway, or want the most rewarding small car to drive; our guide to electric cars for high-mileage drivers is a better starting point for big annual mileages. And check the grant-eligible rivals first: after the £3,750 grant the Hyundai IONIQ 3 undercuts every Dolphin Surf, and the Renault 5 offers five seats at a similar price.

This verdict rests on published data and the UK reviews cited above; EV Compared has not driven the BYD Dolphin Surf.
