Emergency Fund Guide UK: How Much to Save, Where to Keep It and How to Build One From Scratch
Three months of essential outgoings in an account paying 4.50% AER, FSCS-protected to £120,000, accessible the same day. That is the entire emergency-fund debate in one sentence — yet the Money and Pensions Service reports that 11.5 million UK adults have less than £100 in savings. The gap between what works and what people hold is enormous, and it is closable in eighteen months for most households who run the maths once and automate the answer. This guide does that maths. It shows how to size the fund against your essential expenses (not your salary), where to keep it now that easy-access cash ISAs at Chip and Plum clear 4.50% with the FSCS deposit cap raised to £120,000 since December 2025, and how to fund it from a standing order without feeling the bite. The Bank of England base rate sits at 3.75% and CPI inflation is 3.3% — the spread between top easy-access rates and inflation is wider than it has been for fifteen years. Cash savers have rarely had it better. This article is for general information only and does not constitute regulated financial advice.
