October 2026 brought the closest result on record for UK electric car sales. Battery electric cars took 32.0% of new registrations, while petrol took 37.2%. The gap is now just 8,018 cars. That small number matters for any curious buyer, because it shows how fast the forecourt is changing and why discounts are shaping the market.
What October 2026 actually showed
The UK registered 152,730 new cars in October 2026, up 5.4% on a year ago. That was the 11th month in a row of market growth, according to the Society of Motor Manufacturers and Traders (SMMT).
A BEV is a battery electric vehicle. It runs only on electricity. A PHEV is a plug-in hybrid. It runs on electricity for short trips and petrol for longer ones. An HEV is a hybrid without a plug. A mild hybrid is a petrol or diesel car with a small electric boost, and the SMMT counts it as petrol or diesel in its headline figures.
Here is the October split in plain terms:
- BEVs: 48,858 cars, up 32.7% on last year, 32.0% share. That is almost one in three new cars.
- Petrol including mild hybrids: 56,876 cars, down 11.6%, 37.2% share. That is just over one in three.
- PHEVs: 22,898 cars, up 30.1%, 15.0% share.
- HEVs: 18,287 cars, down 5.0%, 12.0% share.
- Diesel: 5,811 cars, down 15.9%, 3.8% share.
- Total market: 152,730 cars, up 5.4% on last year.
That 32.0% is also the highest monthly BEV share of 2026 so far, up from 28.3% in the September plate-change month. Petrol and diesel shrank. Hybrids without a plug also slipped. Together, electrified cars made up 59.0% of the month, or almost six in ten registrations. For the year to date, the UK has registered 503,805 BEVs through the SMMT vehicle data portal, up 30.4%, for a 26.6% share. Petrol is down to 41.1% so far this year, from 47.2% at the same point in 2025.
When could electric overtake petrol?
No one can name the month with certainty. Two forecasts point in different directions, and buyers should treat both as estimates rather than promises.
Electrek extended the SMMT monthly trend in a straight line. It found petrol losing about half a point of share per month and BEVs gaining about 0.36 points. On that slow path, the lines cross around August 2027 at roughly 33% each. That analysis counts mild hybrids as petrol, which is how the SMMT counts them.
December could be faster. BEV share often jumps in December as makers push cars to meet annual targets. BEVs reached 31.0% in December 2024 and 32.2% in December 2025, when petrol was at 39.4%, according to the Electrek review of SMMT data. Electrek notes that if December 2026 runs about five points above last year for BEVs and seven points below for petrol, BEVs could reach around 37% and pass petrol for the first time in headline terms.
The SMMT urges caution. Its own November outlook forecasts BEV share at 27.2% for the full year of 2026. That implies roughly 31% for November and December combined, which would make a December crossover a much closer call. The trade body expects the year-end push to repeat the pattern of the past two years, but not to close the full gap.
There is also a definitional twist. On a stricter count that moves mild hybrids out of petrol and into hybrids, BEVs already outsold every other fuel type in August. On the headline count most buyers see, they have not yet done so. That is why the same market can look both decided and still open.
A crossover that discounts built
This is the organising idea for the whole story. Demand did not arrive on its own. It was priced into being.
The ZEV Mandate is the UK rule that sets the share of new cars that must be zero emission each year. For 2026, the target is 33%. For 2027, it is 38%. For 2028, it is 52%. Makers that miss can buy credits from others or use flexibilities, and no maker has paid a fine to date, but the pressure to register more BEVs is real.
The SMMT says makers have spent billions on price cuts, low and 0% finance, deposit contributions and even subsidised charging. The government adds its own Electric Car Grant alongside wider motoring tax policy set out by GOV.UK. More than 180 BEV models are now on sale in the UK, with average range above 300 miles on a single charge, according to the SMMT release.
For buyers, that means lower monthly payments than list prices suggest. A 0% deal or a deposit contribution can cut the effective cost by thousands of pounds. It also means December is often the cheapest month, because makers push hardest then. The SMMT warns that such support cannot last for ever, and that heavy discounting can reduce used values. Buyers who plan to sell in three years should weigh a low new price today against a lower trade-in value later.
Who is winning the growth
The growth is not spread evenly. Chinese-owned brands are rising fastest, while some long-time leaders are quiet.
In October, Jaecoo registered 6,089 cars, more than double a year ago. Chery nearly tripled to 3,707. Leapmotor doubled to 1,773. BYD rose 73% to 6,065 cars. MG rose 85%. These brands mix keen prices with well equipped BEVs and PHEVs, which suits fleet buyers who now take 58.9% of the market.
Tesla had a slow October by contrast. It registered 282 cars in the month, down 45% on a year ago. October is often slow for Tesla in the UK because shipments cluster late in each quarter. The brand is still up 31% for the year to date at 46,526 cars after a strong September. Yet it placed no model in the October top 10 for BEVs. That list was led by the Skoda Enyaq with 1,568, the Mini Countryman with 1,494 and the Jaecoo 5 with 1,465, followed by the Vauxhall Frontera, Audi Q4 e-tron, BYD Seal, BMW iX3, Ford Puma electric, Kia EV3 and Leapmotor B10.
Fleet choice explains part of this shift. Company car tax still favours BEVs. Fleets buy in bulk.
When fleets move, market share moves with them. Private buyers follow more slowly, which is why private demand rose only 4.1% in October.
What it will cost to run an EV next
Two tax decisions will shape buyer maths more than any showroom poster.
First, eVED. That stands for Electric Vehicle Excise Duty. It is a new mileage-based road tax for electric and hydrogen cars from 1 April 2028. The confirmed rate is 3 pence per mile for BEVs. PHEVs will pay 1.5 pence per mile. A driver covering 8,000 miles a year in a BEV would therefore pay about 240 pounds a year, before inflation uplifts. That replaces some of the fuel duty that petrol drivers pay at the pump.
Second, VAT on public charging. Home electricity carries 5% VAT. Public charge points carry 20% VAT. The Budget kept that gap in place. For drivers with a driveway, home charging stays much cheaper. For drivers without one, public charging stays dearer. That gap matters most in cities and for renters.
Charging access is improving, but from an old base. The UK passed an early marker in 2019 when public EV charging sites outnumbered petrol stations, yet the network still needs cheaper and more reliable rapid hubs. Buyers who cannot charge at home should check local rapid prices and reliability before choosing a BEV, and test a PHEV as a bridge where daily miles are short.
Frequently asked questions
What is the percentage of electric vehicles in the UK?
In October 2026, BEVs were 32.0% of new registrations. For the first ten months of 2026, they were 26.6%. Petrol was 37.2% in October and 41.1% for the year to date. These are shares of new cars sold, not shares of all cars on the road, which remain much lower because cars stay in use for many years.
How many Chinese cars are sold in the UK?
The SMMT does not publish a single Chinese total, but October brand data show rapid growth. Jaecoo, Chery, Leapmotor, BYD and MG all grew by 70% or more year on year. Much of this growth is in BEVs and PHEVs. Fleet buyers are taking a large share of these cars.
What is the 80% rule for EV charging?
It is a rule of thumb, not a law. Many makers suggest charging to 80% for daily use to slow battery wear, then using 100% for long trips. Rapid chargers also slow markedly after 80%, so stopping there often saves time. Check the handbook, because advice varies by battery type.
Will electric cars outsell petrol in December 2026?
They could, but it is not certain. Electrek projects a December crossover if recent year-on-year gains repeat. The SMMT forecasts a full-year BEV share of 27.2%, which implies a lower November and December average of about 31%. Treat December as a possible first, and August 2027 as the trend-based date.
What is the ZEV Mandate target for 2026 and 2027?
The target is 33% zero-emission sales in 2026, rising to 38% in 2027 and 52% in 2028. The SMMT forecasts actual BEV shares of 27.2% in 2026, 32% in 2027 and 37.5% in 2028. The gap would therefore rise from about six points this year to 14.5 points in 2028. The government has opened a review of the rules.
What to watch next
Watch November and December together. If BEVs hold above 31% across both months, the SMMT full-year forecast will prove cautious. If they slip back towards 28%, the trend path to August 2027 stays on track.
Watch prices more than promises. Discounts, finance rates and grant terms will decide how fast the last 8,018 cars close. Policy can help by making public charging cheaper and by giving long-term certainty on grants. Until then, the milestone is near, but it is built month by month on the forecourt, not guaranteed in Whitehall.
