Autumn Budget 28 October 2026: 8 Rumours vs What's Already Set

The Chancellor delivers the Autumn Budget on Wednesday 28 October 2026, and the rumours are already louder than the facts. For most UK households, several of the biggest money changes for 2027 are already decided: income tax thresholds stay frozen until April 2031, VAT has been off electricity bills since 1 October, and the cash ISA allowance for under-65s falls to £12,000 from April 2027. What is genuinely open on Wednesday is narrower than the headlines suggest.

Below are eight rumours you will hear this week, what is actually set, and what each one could mean in pounds for an ordinary household. Nothing reported as "expected" is official until the Chancellor sits down.

Rumour 1: "Income tax is going up"

Reality: the government has repeated its commitment not to raise the rates of income tax, employee National Insurance or VAT, according to Grant Thornton's Budget preview (updated 20 October 2026). The bigger effect is quieter: the Personal Allowance of £12,570 and the other thresholds are already frozen until April 2031 under the policy announced in the 2025 Budget. As pay rises, more of your income is taxed at 20% or 40% without any rate changing. The Institute for Fiscal Studies estimates that restoring inflation-linked uprating from April 2027 would cost around £8.4 billion a year, which is why few expect it. The minimum wage is also expected to rise, and we calculated what a National Living Wage of about £13.20 would mean for take-home pay.

Rumour 2: "The Budget will cut my electricity bill"

Reality: the cut has already happened. Since 1 October 2026, VAT on household electricity has been 0% instead of 5%, saving an average of £45 a year (Department for Energy Security and Net Zero). You do not need to claim it; it covers fixed tariffs and prepayment top-ups. Gas still carries VAT. It is funded for the 2026 to 2027 financial year, and MoneySavingExpert reported it as running to 31 March 2027. Whether it is extended is one of the genuine Budget questions, but it is speculation for now.

Rumour 3: "The Warm Home Discount is going up to £250"

Reality: today it is £150, paid automatically to around 6 million eligible households this winter (GOV.UK). Which? reports that the Budget may add a further £100, which would make it £250, but that is a report, not a decision. If you qualify, plan with £150 and treat anything extra as a bonus. Our Warm Home Discount 2026 guide explains who gets it and when letters arrive.

Rumour 4: "Pensioners will start paying tax on the State Pension"

Reality: the full new State Pension is expected to be £13,036 a year in 2027 to 2028, which is £466 above the frozen £12,570 allowance. Taxed at 20%, that would be £93.20 a year for someone with no other income. PensionBee reports that the Pensions Minister has confirmed pensioners whose only income is the State Pension will not pay income tax on it. How that works in practice may be set out on Wednesday. If you also have a workplace or private pension, you may already pay tax, and that is not changing because of this rumour. See our State Pension April 2027 explainer.

Most of what will change your 2027 budget was decided before Wednesday. The frozen allowance alone keeps pulling more of every pay rise into tax until 2031.

Rumour 5: "The cash ISA cut is new"

Reality: it was announced in the 2025 Budget. From April 2027, under-65s can put at most £12,000 a year into cash ISAs, down from £20,000, while the overall ISA allowance stays at £20,000 (Low Incomes Tax Reform Group). If you were planning to use a large cash ISA allowance, this tax year, ending 5 April 2027, is your last chance at the old limit.

Rumour 6: "Petrol goes up the day after the Budget"

Reality: the 5p fuel duty cut is currently due to end after 31 December 2026, with staged rises pencilled in from January 2027. PetrolPrices.co.uk notes the Treasury has not confirmed the exact phasing, and PensionBee lists the expected steps as 3p in January and 2p in March 2027. What it costs you: a 5p rise is close to 6p a litre once VAT is added. For a 45-litre tank filled every two weeks, that is about £2.70 a fill, or around £70 a year. Our UK money calendar to January 2027 keeps track of these dates.

Rumour 7: "Student loan repayments are about to fall"

Reality: the Plan 2 repayment threshold is £29,385 in 2026 to 2027 (Student Loans Company) and is due to be frozen at that level for three years from April 2027 (LITRG). Which? reports pressure to reverse the freeze, but nothing is confirmed. Repayments are 9% of income above the threshold:

Our calculations, UK, Plan 2, 9% above £29,385. Illustrative, before any Budget change.

Rumour 8: "The mansion tax will catch £1.5 million homes"

Reality: reports that the threshold would fall from £2 million to £1.5 million have reportedly been ruled out (Grant Thornton). The High Value Council Tax Surcharge on homes worth £2 million or more in England is due from April 2028. For the vast majority of households, normal council tax bills for April 2027 matter far more, and those are set by local councils in early 2027.
