The price cap rises 4%, and VAT on electricity drops to nothing
From 1 October the capped rates go up: a typical home paying by direct debit goes from £1,663 a year to £1,723. Gas is up around 8% and electricity barely moves, because VAT on household electricity in England, Scotland and Wales falls from 5% to zero for six months at the same time. Northern Ireland keeps the 5%.
The zero rate ends on 31 March 2027, so an electricity bill goes up again in April even if nothing else changes. Fixed deals a few per cent under the cap are available now, and a fix locks the price but not the exit fee, so check that before you sign.
