Our Expert Opinion on Principality Building Society 1 Year Fixed Rate Bond

Jonny PeaseCo-Founder, DepositScout

Principality Building Society's 1 Year Fixed Rate Bond pays 4.80%, which sits below the market average for fixed-rate accounts, trailing the category leader by 0.57%. It does beat CPI inflation of 3.1% by 1.70 percentage points, so your money grows in real terms, but if rate is your priority I would look at Atom Bank's 1 Year Fixed Saver at 4.90% instead. The genuine catch here is the usual one for fixed bonds: no access until maturity, so only commit money you can leave untouched for the full year.
