Nationwide Building Society rewards more than 40,000 members with a £175 switching bonus within just two months. Current account switches surpass one million for the third straight year, driven by consumers hunting better deals late in 2025.
Record Switching Activity in Late 2025
Nationwide attracts 41,450 customers from July to September, thanks to its £175 incentive and profit-sharing payments. The Current Account Switch Service (CASS) records 350,114 switches in the final quarter alone—the busiest period of the year.
CASS automates transfers by redirecting payments to new providers. Note that some switches occur outside this service, so totals exclude those. Overall, 2025 sees 1,054,521 switches, down from peaks in 2023 and 2024 when high interest rates boosted savings options. Rates begin falling from August 2024.
Top Gainers and Biggest Losers
Nationwide leads Q3 gains per CASS data, released three months later. Monzo follows with 9,934 new accounts, and NatWest adds 8,731.
Santander loses nearly 20,000 accounts in the same period. Halifax sheds 17,341, and JP Morgan’s Chase drops 7,623.
Experts Weigh In on Market Competition
John Dentry, product manager at Pay.UK, which runs CASS, states: “That level of activity signals a healthy, competitive banking market where consumers shop around for accounts that fit their needs.”
He adds: “When every pound counts, consumers should switch quickly, easily, and with a guaranteed service.”
Andrew Hagger, personal finance expert at Moneycomms, highlights Nationwide’s dominance: “It stands head and shoulders above competitors, gaining 404,207 customers over two years.”
Alastair Douglas, CEO of TotallyMoney, notes switching “heats up” end of 2025. “Expect no slowdown soon, with seven banks offering at least £175 incentives: Co-op, First Direct, HSBC Premier, Lloyds, Nationwide, Santander, and TSB.”
Douglas continues: “New banks often deliver better service, interest-free overdrafts, or branches. Loyalty rarely pays—switching usually does.”
