NS&I (National Savings and Investments) Review

Depends

Should I use NS&I (National Savings and Investments)?

NS&I offer 100% secure savings - nsandi.com

· 21 hours ago

Buy if you are a UK saver who values absolute capital safety over returns — deposits are 100% government-backed. Avoid if you chase top rates or expect fast service; delays and rate lag are well documented.

Confidence

Medium. Based on ~25 public sources; several results were unrelated noise (G2 pages, CVE posts, unrelated people named 'Nsandi') and excluded.

low

£557m sits in forgotten accounts — track old NS&I holdings.
