What is NS&I? UK Sovereign-Backed Savings Explained

NS&I is the UK government's own retail savings bank, owned by HM Treasury and used as a debt-funding mechanism rather than a normal commercial bank

NS&I deposits are not subject to the £85,000 FSCS limit - protection is effectively unlimited because the Treasury itself stands behind every product

The Premium Bonds prize fund rate is 3.30% until the June 2026 draw, then rises to 3.80% from July 2026, with odds improving from 23,000 to 1 down to 22,000 to 1 per £1 bond

Direct Saver pays 3.45% AER, Income Bonds 3.45% AER, Direct ISA 3.80% tax-free, Green Savings Bonds 3.82% on a 3-year fix - rarely best-buy, always sovereign-backed

NS&I is one of the few UK savings institutions structurally on the saver's side because there are no shareholders to extract value, only a Treasury that wants your money cheaply
