Car rule changes coming in the UK — and what is not confirmed
Three dated changes reach cars already on the road: home electricity in Great Britain carries no VAT on supplies from 1 October 2026 to 31 March 2027, which cuts the cost of charging an electric car at home; fuel duty on petrol and diesel is legislated to rise from 52.95p to 55.95p a litre on 1 January 2027 and to 57.95p on 1 March 2027 — about 6.0p a litre at the pump once VAT is added — unless Budget 2026 changes it; and from 1 April 2028 electric and plug-in hybrid cars pay a mileage charge that applies to cars already on the road rather than only to new ones. Almost everything else being written about “the 2030 ban” governs what manufacturers may sell new, not what you may own, buy used or drive. This page lists only changes that carry both a date and the instrument creating them, and then lists separately the claims we could not trace to any source at all — including, awkwardly for a lot of published articles, that the 2030 ban is already law.
What is actually confirmed
The consultation that defines the 2030 phase-out closes
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.

The historic vehicle tax exemption advances another year
Vehicle tax exemption for historic vehicles runs on a rolling 40-year rule. GOV.UK currently states that a vehicle built before 1 January 1986 can stop paying vehicle tax from 1 April 2026; the cut-off advances by a year each April. Unlike the MOT exemption, this one is not automatic — you have to apply to move the vehicle into the historic tax class.

Electric and plug-in hybrid cars start paying per mile
Electric Vehicle Excise Duty adds 3p per mile for battery electric and hydrogen fuel cell cars and 1.5p per mile for plug-in hybrids, charged alongside vehicle tax rather than instead of it. It applies to cars already on the road, and keepers begin paying at their first vehicle tax renewal after that date.

The registration mix tightens sharply, and used supply follows
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 — so it is the other side of the 80% target, not a competing figure.

All new cars and vans zero emission
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.

Dated changes to running costs
These change what it costs to run a car you already own, rather than what may be sold new.
No VAT on home electricity in Great Britain
Supplies of domestic electricity in England, Wales and Scotland are zero-rated for VAT in this window, so home charging costs less; Northern Ireland keeps the reduced rate. After 31 March 2027 the rate is expected to return to the standing reduced rate of 5% unless the window is extended — HMRC has not published the position after 31 March 2027.

Fuel duty rises to 55.95p a litre
First of two steps unwinding the cut: 3p of the 5p comes back. These are the legislated default rates. The government has said final rates will be confirmed at Budget 2026, and the temporary cut has already been extended several times, so treat this as what happens if nothing changes rather than as a decision that has been taken.

Fuel duty rises to 57.95p a litre
The remaining 2p returns, restoring the rate that applied before March 2022. These are the legislated default rates. The government has said final rates will be confirmed at Budget 2026, and the temporary cut has already been extended several times, so treat this as what happens if nothing changes rather than as a decision that has been taken.

What is repeated everywhere and is not confirmed
Each of these is stated as settled fact somewhere prominent. None could be traced to a dated primary source. That does not make them false — several may well happen — but none of them is something to make a buying decision on today.
“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”
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 MOT is moving to every two years, or first test at four years”
Proposed and rejected. No commitment to change the current schedule could be found.
“The MOT will soon include an EV battery health check”
No government commitment found. Statements go no further than looking at whether improvements could be made to the MOT for electric vehicles.
“A named Clean Air Zone or ULEZ change is confirmed for a given date”
Proposals and press reporting exist for several cities, but no commencement-dated change could be confirmed. Check the specific local authority before assuming a car will or will not be charged.
“The Electric Car Grant ends on a specific date”
Funding is stated as available until financial year 2028 to 2029, but GOV.UK describes the scheme as subject to amendment or early closure with no fixed end date.
What this means if you are buying a used car now
Nothing announced stops you owning or driving a petrol or diesel car. Every dated measure concerns new sales or how tax is collected. There is no published date after which a used petrol car cannot be bought, sold or driven.
If you are buying electric, price in the mileage charge. It starts in April 2028, applies to cars already registered, and scales with how far you drive — what pay-per-mile means for a used electric car works through the arithmetic, and it changes the running-cost comparison more for high-mileage drivers than for anyone else.
Emissions charges are local and now, not national and future. Whether a car is charged in a clean air zone depends on its emissions standard and on the specific scheme, which our clean air zone checker resolves for a given car. That is a real cost today, unlike most of what is written about 2030.
The used mix will shift gradually. The registration percentages step down to 2030, and those cars reach forecourts about three years later. If you want a petrol or diesel car in the 2030s, the supply thins rather than stops — and what a used petrol or diesel looks like today is a better guide to your next purchase than a headline about 2035.
