Many customers stick with big banks like HSBC, Lloyds, NatWest, and Barclays out of habit, even though they may not offer the best service.Consider switching to challenger banks like Chase, Monzo, and Starling for better service quality and features.Switching banks can be beneficial, with incentives like cash bonuses for moving accounts and easy, guaranteed processes.Avoid relying on overdrafts due to high interest rates; consider using a 0% credit card for better debt management.Leaving excess cash in accounts with little to no interest can result in loss of value; opt for accounts with higher interest rates.It's important to read the fine print on savings accounts to understand any restrictions or hidden fees.Regular saver accounts may offer good rates but limited monthly contributions; assess if they suit your savings goals.Packaged bank accounts with monthly fees for perks like insurance may not be cost-effective; review the benefits you actually need.Carefully evaluate packaged account benefits to ensure you are getting value for the fees you pay.Consider opting for unbundled services rather than packaged accounts to save money on unnecessary perks.
