UK budget proposes bank surcharge rise to 6% alongside energy support

The UK’s 2026 budget proposes raising the bank corporation-tax surcharge from 3% to 6% for 15 months through 31 March 2028, according to the Treasury’s 28 October announcement.

The package also includes a £100 Household Energy Payment for up to 20 million households in 2027. In England it targets properties in council-tax bands A–D, with corresponding funding for other UK nations.

The 6% figure is the bank surcharge, not the overall corporation-tax rate. These are forward-looking budget measures; implementation dates and eligibility conditions determine their practical effect on lenders and households.
