Emergency fund: how much to save and where to keep it
Quick answer: An emergency fund is easy-access cash for unexpected costs. Aim for three to six months of essential outgoings, kept in a separate easy-access savings account so it is safe but reachable when you need it.
An emergency fund is the financial cushion that stops a surprise bill turning into expensive debt. This guide explains how big it should be, where to keep it, and how to build one even on a tight budget.

How much you need
A common target is three to six months of essential spending — rent or mortgage, bills, food and transport. If your income is irregular or you are self-employed, lean towards the higher end. If you are clearing expensive debt, a smaller starter fund of around £1,000 first can stop new debt while you focus on repayments.
Base the figure on your essentials, not your total spending, so the goal stays realistic.
Where to keep it
Use an easy-access savings account separate from your everyday current account, so the money is reachable within a day or two but not so visible that you spend it. Pick an FCA-authorised provider so your savings are FSCS-protected up to £85,000.
Avoid tying an emergency fund up in investments or notice accounts — the point is instant availability without risk of a loss when you need the cash.
Common questions
How big should my emergency fund be?
Three to six months of essential outgoings is the usual guide. The more variable your income, the larger the cushion you want.
Should I invest my emergency fund?
No. It should stay in cash in an easy-access, FSCS-protected savings account so it is safe and instantly available — investments can fall in value just when you need the money.
