Highest AER first, then the lower minimum deposit. Ranking rules version 1.2.0. AER shows what you'd earn in a year including any bonus. Rates can change at any time: check with the bank before you apply. Lifetime ISA rates are the provider's interest only; the government's 25% bonus is not in the AER. Lifetime ISAs, Junior ISAs and children's accounts are ranked only against their own kind, and Premium Bonds, which pay prizes rather than interest, are never ranked: see NS&I and Premium Bonds. NS&I accounts are backed by HM Treasury, not the FSCS. We list accounts held directly with the bank, not savings sold through apps and platforms such as Revolut, Trading 212 or Raisin. "Beats inflation" means the AER, and the rate after any bonus, is above CPI inflation of 3.5% (September 2026, ONS), before tax. How we rank, what we don't list and how we're paid.
