Can I still buy a petrol car after 2030?

Yes, and nothing that has been announced would stop you. The phase-out applies to what manufacturers may sell NEW. The government has said in terms that it is not banning the use of petrol and diesel cars, that the decisions apply only to new vehicles, and that existing cars can continue to be driven and sold second-hand. There is no end date for buying a used petrol car, and none has been proposed.

Where the confusion comes from

Almost every mention of 2030 drops the word new. Once that word goes, a rule about what manufacturers may register turns into a rule about what you are allowed to own, and it reads like a deadline for getting rid of a car you already have. It is not one.

Two things everyone repeats that are not accurate

We keep a list of claims about UK motoring rules that are stated as settled fact but cannot be traced to a dated primary source. Two of them sit squarely on this question.

“The 2030 petrol and diesel ban is already law”

No commencement-dated instrument creating a 2030 prohibition could be found. What exists is a stated policy position and a consultation, still open, on how the phase-out should be defined.

“The ZEV mandate means 80% of every manufacturer’s new cars must be electric in 2030”

This is not pedantry about wording. If you believe a ban is already law, you may sell a perfectly good car early, or pay over the odds for an electric one, on a deadline that does not exist.

What IS settled, and what it means for the forecourt

Schedule 6 to the Vehicle Emissions Trading Schemes Order 2023 steps the percentage of total registrations used to calculate a manufacturer’s allowances down year by year: for cars 67% in 2026, 62% in 2027, 48% in 2028, 34% in 2029 and 20% in 2030. Vans run 76%, 66%, 54%, 42% and 30%. Cars registered under those years reach the used market roughly three years later, so this is the clearest available signal of what will be on forecourts in the early 2030s.

The 20% is the share of new cars still allowed to be non-zero-emission — petrol, diesel or hybrid — under the non-zero-emission car registration trading scheme (CRTS), so it is the other side of the 80% target, not a competing figure.

That is the part worth planning around. It says nothing about what you may buy, and everything about what will be available to buy used in the early 2030s — because a car registered new in 2029 typically reaches the used market around 2032.

And 2035

The stated government position, confirmed in April 2025, is that new full hybrids and plug-in hybrids may still be sold between 2030 and 2035, and that from 2035 all new cars and vans will be zero emission. This is a policy position rather than a commencement-dated prohibition, and it has been revised more than once.

Still being decided: 23 October 2026. The government is consulting on how the 2030 phase-out of new petrol and diesel cars should be defined. Until it reports, the precise legal shape of "2030" is not settled — which is why no source can tell you exactly which new cars will be sellable that year.

What should actually change your mind about a petrol car

Not a ban — the running costs, which are set by completely separate decisions and do have dates.

Fuel duty is scheduled to rise in two steps during 2027, unwinding the temporary cut.
From 1 April 2028, electric and plug-in hybrid cars start paying per mile — which matters if you are weighing petrol against electric, because it narrows the running-cost gap. How that works.
Clean air zone charges are set city by city, not nationally. Check the specific car with the Clean Air Zone checker.

If you want the comparison in money rather than in principle, the EV versus petrol calculator puts an annual figure on two specific cars, and the dated rule changes lists everything confirmed between now and 2035 with its instrument.

How we check this

Every date on this page comes from a primary instrument or a government publication, reviewed 2026-09-19. Where a widely repeated claim could not be traced to a dated source, we say so rather than repeat it. This is a general explanation of announced policy, not legal advice about a particular vehicle.

Frequently asked

Will petrol cars be banned in 2030?

No. What is proposed applies to new cars only. The government has stated that it is not banning the use of petrol and diesel cars and vans, and that existing vehicles can continue to be driven and sold on the second-hand market. There is no proposal to stop you buying, owning or driving a used petrol car.

Is the 2030 phase-out actually law?

Not in the form it is usually described. No commencement-dated instrument creating a 2030 prohibition could be found. What exists is a stated policy position and a consultation, still open, on how the phase-out should be defined. What is settled law is the schedule of registration percentages manufacturers are measured against, which is a rule about their new-car mix.

Do 80% of new cars have to be electric by 2030?

80% is the government’s stated commitment for 2030 and appears on GOV.UK, so the headline is real. What is not right is reading it as a fixed per-manufacturer floor. The legislation does not use the figure at all: Schedule 6 to SI 2023/1394 sets 20% for cars in 2030 as a "percentage of total car registrations for the purpose of calculating CRTS allowances". Compliance runs through tradeable allowances, borrowing and conversion from CO2 performance, so an individual maker’s delivered share in a given year can sit either side of the headline. The 20% is the share of new cars still allowed to be non-zero-emission — petrol, diesel or hybrid — under the non-zero-emission car registration trading scheme (CRTS), so it is the other side of the 80% target, not a competing figure.

Will I still be able to get petrol after 2030?

Nothing announced closes filling stations or stops petrol being sold. With tens of millions of petrol and diesel cars on the road and no restriction on driving them, demand does not disappear at a date. The sensible expectation is that availability follows demand gradually over decades, not that it stops.

What actually changes for someone buying a used petrol car?

Two things, and neither is a ban. The mix of cars reaching the used market shifts as new registrations shift, so newer petrol cars become scarcer through the 2030s. And running costs change by other routes — fuel duty, vehicle tax and clean air zone charges are all set separately from the phase-out.

Should I avoid buying a petrol car now?

That is a question about how long you plan to keep it and what it costs to run, not about legality. A petrol car bought today can be driven and resold indefinitely as things stand. Weigh the running costs and the resale outlook rather than a date you have read about.
