BYD Flash Charging UK: 300 chargers at 1,500kW, open to other EVs

BYD plans a UK network of 300 Flash chargers rated at up to 1,500kW, which it says can take a compatible car from 10 to 97% in nine minutes. Autocar described them as the UK’s fastest EV chargers, and BYD says any car with a CCS2 socket will be able to plug in. The catch for most UK drivers is that only BYD’s own Flash-equipped cars get the full speed, and the first of those, the Denza Z9 GT, is not due to reach customers until this quarter.

BYD first showed the system in Britain on 11 June 2026 at its UK headquarters in Uxbridge, charging a Z9 GT from 10 to 97% in nine minutes (BYD UK Media). BYD’s Flash network passed 10,000 stations in China in August (EV Infrastructure News). The UK questions are how many chargers arrive, where, and at what price.

What exactly has BYD promised?

The timing is looser than the headline. BYD UK’s question-and-answer release says it will install 300 Flash chargers nationally “within the next 12 months” (BYD UK Media), and Autocar reported that the first UK site would go live “in the coming weeks”. CAR Magazine and Electrifying both reported the target as the end of 2026, as did coverage of BYD’s June UK debut, which said the 300 would go in at Denza stores and other locations.

With less than three months of 2026 left, we treat the end of this year as the optimistic case and the 12-month wording as the more realistic guide. BYD is also aiming for 3,000 Flash sites in Europe and 6,000 outside China (Carscoops).

Date	Milestone
April 2026	BYD confirms megawatt Flash chargers for Europe, open to all brands
11 June 2026	First UK demonstration at Uxbridge: Denza Z9 GT charged 10 to 97% in nine minutes
July 2026	Denza Z9 GT UK prices announced
Q4 2026	First UK Z9 GT customer deliveries due
End of 2026	Reported target for 300 UK chargers

Where will the Flash chargers go?

BYD says it will prioritise its own BYD and Denza sites in core towns and cities, followed by motorway service areas and existing charging hubs (BYD UK Media). Launch coverage said the first 35 to 40 would go in at BYD and Denza retailers, with later sites at food and coffee stops such as KFC, McDonald’s and Starbucks, plus airports and railway stations (Autocar).

Starting at dealers suits BYD, which controls the land, but is less useful on long trips. Until motorway sites arrive, Flash chargers will sit alongside the ultra-rapid hubs you already use, including the new sites that opened in September.

Can other electric cars use BYD Flash chargers?

Yes, with a big caveat. BYD says the chargers use the CCS2 connector and are open to every manufacturer, but a car from another brand will be limited by its own maximum charging speed rather than by the charger (BYD UK Media). If your car peaks at a certain rate on a 400kW charger, it will peak at the same rate on a Flash unit. Our fastest charging electric cars ranking shows where your model sits.

The full speed needs a car built for it. In the UK that starts with the Denza Z9 GT, priced from £105,000 as a full EV and £95,000 as a plug-in hybrid that joins the range later, with first EV deliveries due in the fourth quarter (electrive). These are BYD’s own claims for the electric version:

BYD claim	Charge	Time	Range added
Ready in 5	10 to 70%	5 minutes	223 miles
Full in 9	10 to 97%	9 minutes	323 miles
Cold Add 3	20 to 97% at minus 30°C	12 minutes	Not quoted

How much will BYD Flash Charging cost?

Final UK tariffs are not out, and BYD has not yet published what drivers of other brands will pay.

Bono Ge, head of BYD UK, has said the company is aiming for around 50p per kWh, telling Autocar that “in the ideal situation, we want to be sub-50 pence” (EV Powered). Reports of the Z9 GT’s UK launch say buyers get 18 months of free Flash Charging, which some describe as 12 months plus a further six for the first customers.

Network or benchmark	Pay-as-you-go price
BYD Flash (BYD’s aim)	Around 50p per kWh
Believ	66p per kWh
Sainsbury’s Smart Charge	72p per kWh
UK rapid and ultra-rapid average, August 2026	77p per kWh

Source: Zapmap, which names Believ and Sainsbury’s Smart Charge among the networks charging less than the rapid and ultra-rapid average.

On a 60kWh top-up, 50p per kWh costs £30, against £46.20 at the 77p average. Our October charging prices report has the wider picture.

How does a 1,500kW charger run without a huge grid connection?

The power comes from batteries on site. Each charger has 370kWh of storage in two 185kWh units, refilled from the grid at between 100kW and 560kW, so BYD says a site needs no bigger grid connection than slower chargers (The EV Report). BYD says the storage is topped up gradually through the day, and EV Powered reports that BYD aims to undercut rival networks on price.

The trade-off is the size of that buffer. Once a run of back-to-back full-speed sessions has drained the 370kWh store, the charger depends on the much slower grid feed to refill it.

What this means for you

If you are buying a Z9 GT, Flash Charging is a real part of the appeal, especially with a free introductory period. For everyone else, the draw is price rather than speed. If the rate other brands pay lands near 50p, it would undercut every pay-as-you-go price in our table; if it lands near the 77p average, it would cost more than Believ or Sainsbury’s Smart Charge.

We would not choose a car or plan a journey around the promise yet. Wait for BYD to publish the tariff other brands will pay and a live site map, then compare it with your usual network.
