The crackdown will also halt the scourge of plastic littering after five million vapes a week were thrown away last year — quadruple the number from 2022.
The Government expects devolved nations in Scotland, Wales and Northern Ireland to implement the same cut-off date.
But refillable vapes will remain available as doctors use them to help people quit smoking.
The move follows mounting fears that more kids are illegally buying disposables, many of which now come in bright packaging with flavours including bubblegum, candy floss and cola.
Chancellor Rachel Reeves said: “I can confirm that the Government will renew the Tobacco Duty escalator for the remainder of this Parliament at RPI+2%…”
She went on to say they will “increase duty by a further 10% on hand-rolling tobacco this year” and “introduce a flat rate duty on all vaping liquid from October 2026”.
Ms Reeves said this will be alongside an “additional one off increase in tobacco duty” to maintain the incentive to give up smoking.
“And we will increase the Soft Drinks Industry Levy to account for inflation since it was introduced…as well as increasing the duty in line with CPI each year going forward.
“These measures will raise nearly £1bn per year by the end of the forecast period.”
PM Sir Keir Starmer is braced for further accusations of “nanny state†interference following a slew of measures, including the proposed outdoor smoking ban.
RACHEL Reeves will be grilled in a special Budget edition of The Sun’s Never Mind The Ballots show today.
Our Political Editor Harry Cole will put the Chancellor on the spot shortly after she’s finished delivering her crucial address in the House of Commons.
It will be available to watch on thesun.co.uk, YouTube and Sun social channels at 5.30pm.
Topics will include her decision on whether to spare motorists a fuel duty rise, and the expected eye-watering tax rises she will impose.
