UK Savers Forfeit £12bn Annually in Missed Interest as Bank Switching Incentives Rise to £220
British savers are collectively losing around £12 billion per year in missed interest by staying with their existing banks, according to analysis by Hargreaves Lansdown based on Financial Conduct Authority data. A survey of 3,000 UK adults conducted in August found that nearly two-thirds of British savers have been with the same bank for more than a decade, and only 34% moved their money in the last 12 months. Despite this inertia, more than five banks are currently offering current account switching incentives, with the largest bonus reaching £220. The Current Account Switch Service (CASS), to which over 50 UK banks and building societies are signed up, is designed to remove friction from the process by automatically transferring direct debits, balances and incoming payments within seven working days. AJ Bell personal finance head Sarah Coles notes that banks find switching bonuses worthwhile because they then retain customers as a "captive audience" for additional products. Switching activity does appear on credit reports, meaning customers planning a mortgage or loan application within 12 months are advised to delay.
Why this matters
The £12bn annual leakage from inert savers represents a structural market failure that the FCA has flagged repeatedly but which persists despite the availability of CASS. The current wave of switching incentives, reaching £220, signals intensifying competition among retail banks for deposit bases at a time when interest rates remain elevated and banks have strong incentives to retain low-cost current account funding. For institutional clients, the dynamic raises questions about retail deposit stickiness as a funding metric. The gap between available returns and realised returns also feeds into the broader cost-of-living debate, giving the FCA and Treasury political motivation to revisit consumer duty obligations around proactive rate disclosure.
On the Ground
Retail banking and consumer finance teams will face client questions on FCA Consumer Duty compliance, specifically whether banks' failure to proactively surface better rates breaches the 'good outcomes' standard. Financial regulatory practices will monitor whether this data prompts a formal FCA market study into savings and current account switching. A trainee on this matter would review the FCA's existing guidance on the Consumer Duty fair value requirement, pull together the relevant CASS rules, and draft a regulatory risk memo for a retail banking client.
