Martin Lewis has issued several warnings concerning financial issues affecting UK residents. He revealed that many people in England are overpaying for medical prescriptions, urging them to check for eligibility for free prescriptions or cost-effective alternatives. Additionally, Lewis criticized local authorities for their aggressive council tax collection practices, comparing them to loan sharks and highlighting the severe penalties and psychological harm inflicted on vulnerable individuals, especially those with mental health problems. He also called for regulatory changes to offer grace periods for repayment plans before enforcement actions are taken. Furthermore, Lewis pointed out that hundreds of thousands of homes in England and Scotland may be in the wrong council tax bands, resulting in overpayments and potential back pay worth thousands of pounds.
