There is no single 2026 money-saving rule: your finances may be affected by annual changes to tax thresholds, the National Living Wage, benefits, pensions and the energy price cap. Check GOV.UK for the latest rates and entitlements, and use Ofgem’s information when reviewing your energy deal. Recheck household bills, subscriptions, insurance and mobile contracts, then compare alternatives before renewing. Build or review an emergency fund, prioritise expensive debts, and check whether your savings account still pays a competitive rate; providers and government departments decide rates or eligibility based on your circumstances.
