Emergency Fund Guide UK: How Much to Save, Where to Keep It and How to Build One From Scratch
£6,000 in an easy-access account paying 4.50% AER, FSCS-protected to £120,000 and withdrawable the same day. That covers three months of essential outgoings for a typical single renter — and it still clears August's 3.1% CPI. The problem is that only a minority of UK households actually hold it: the Money and Pensions Service counts 11.5 million adults with less than £100 in savings. This guide sizes the fund against your essential expenses, not your salary, and against what those expenses will cost across 2026/27 after a year of 3%-plus inflation. It shows where to keep the cash now that top easy-access accounts pay around 4.5% and top cash ISAs pay 4.62%, with the FSCS deposit cap at £120,000 since December 2025. The Bank of England holds Bank Rate at 3.75% with its next decision due 17 September, and CPI re-accelerated to 3.1% in August as fuel prices jumped. Cash still beats inflation for now — but the margin is thinner than the headline suggests once tax is taken.
