Yes — NS&I is backed by HM Treasury, meaning 100% of your money is protected regardless of amount. This is safer than the £85,000 FSCS limit at banks.

What interest rates does NS&I pay?

NS&I rates vary by product. Premium Bonds have a 4% prize fund rate. Direct Saver and Income Bonds offer variable rates that change based on market conditions. Check NS&I website for current rates.

Should I use NS&I or a bank?

NS&I offers 100% government backing versus £85,000 FSCS at banks. However, NS&I rates are sometimes lower than best-buy accounts. Choose NS&I for security on large sums, or banks for potentially higher rates.
