Yes, reviewing household bills can be worthwhile, particularly for recurring costs such as energy, broadband, mobile phones, insurance and subscriptions. Start by checking what you actually use, cancelling unwanted services and comparing deals, but check for exit fees, introductory offers ending and whether switching affects your cover or contract. You may also qualify for help such as Council Tax reductions, energy support or a water social tariff, so check the relevant provider or GOV.UK guidance. If bills remain unaffordable, contact providers early and consider free debt advice from organisations such as Citizens Advice or StepChange.
