Our Expert Opinion on Monmouthshire Building Society 5 Year Fixed Rate Bond

Jan WatermannCo-Founder, DepositScout

Monmouthshire Building Society is offering 4.60% fixed for five years, which does beat August 2026 CPI of 3.1% by 1.50%, so your money grows in real terms. That said, the rate sits below the market average for fixed-rate accounts, and the best rate across that category is 5.37%, putting this 0.77% behind the leader. If you want a five-year fix specifically, Hampshire Trust Bank's 5 Year Online Fixed Saver at 5.05% or Skipton Building Society at 5.00% are worth a look. The main catch here is the usual one: no access at all until maturity.
