ISA Transfers and Platform Switching Hit Record Levels Ahead of April Deadline

Investment platforms, banks and building societies reported record ISA transfer volumes in the final weeks of the 2025/26 tax year, as millions of savers took advantage of the sustained period of relatively high savings rates to move their money to accounts offering more competitive returns. The annual ISA season, which traditionally sees a surge of activity in March and early April, was particularly active this year, with providers noting both higher volumes and a marked increase in awareness among first-time ISA investors.
Cash ISA rates above five percent were available from a number of competitive providers, representing a significant improvement on the near-zero rates that persisted during the prolonged period of record-low interest rates. The higher savings rate environment has made ISA sheltering significantly more valuable for those with substantial cash balances, as the tax saving on interest income has grown proportionally with the rates being earned.
Investment platforms focused on stocks and shares ISAs also reported strong transfer inflows, with particular interest in index-tracking funds that provide broad market exposure at low cost. The volatility introduced by the Iran war created opportunities for investors who had been waiting for market weakness before deploying accumulated savings, with the dip in equity valuations during the peak conflict period prompting increased contributions from those taking a long-term view.
Consumer rights groups cautioned savers about the complexity of ISA transfer rules, noting that improper handling of transfers — withdrawing and recontributing rather than completing a formal transfer — could result in contributions counting against the current year’s allowance unnecessarily. The groups called for clearer disclosure from providers about the transfer process and timescales.
