Despite top savings accounts now offering rates between 4% and 7.5%, millions of people are leaving their money in zero or low-interest accounts, losing out on potential earnings. New research from Spring, a savings app owned by Paragon Bank, estimates that Britons are missing out on £20billion in lost interest every year, with £526billion sitting idle in current and low-interest savings accounts.

Derek Sprawling, managing director of savings at the savings app Spring, said: “Inflation now stands at 3.5%, so making sure your money is working as hard as it can is imperative to retain its value.” If your cash isn’t working as hard as it could, here are the top savings accounts of the week to help you make the most of today’s competitive rates.
