What stands out
How the Fixed Saver works
The Fixed Saver has terms from 6 months to 5 years. It opens with 50 to 100,000 pounds and a one week deposit window. No withdrawals are allowed until the term ends. There is no cooling off period. The maximum across all Fixed Savers is 100,000 pounds. The top rate on 20 September 2026 is 5.00% AER on the 5 year term, effective 09/09/2026.
How the Instant Saver Reward rate works
The Instant Saver Reward pays a higher Reward rate in any month with no withdrawals. In a month with a withdrawal, a lower rate applies. The rate reverts to the higher Reward rate the next month. It is a variable account with 24/7 access. Live rates are on the provider's pages and in the tables on this page.
2026 leadership change and results
For the year to 31 March 2026, net operating income was 99.8 million pounds and profit before tax was 9.4 million pounds, up from 5.1 million a year earlier. Arrears and forbearance were 0.9% of the loan book, and total lending passed 5.8 billion pounds. Co founder and CEO Mark Mullen stepped down on 4 September 2026 after 12 years. CFO Andrew Marshall is interim CEO while a permanent successor is sought.
Who the account structure fits
The app only structure fits savers who are comfortable managing accounts on a smartphone and do not need branches or a current account. It can suit those with lump sums for fixed terms or easy access savings, including cash ISAs. It may not fit those who want in branch service, a current account, or regular access to fixed funds. Rainy day money may be better in an easy access account, as Fixed Savers lock funds away.
