About emergency funds — what you need to know

What is an emergency fund?

An emergency fund is money set aside specifically for unexpected costs — such as a broken boiler, a car repair, a sudden loss of income, or an unexpected bill. It is kept in a separate, easy-access account and not touched for planned spending.

How much should I save for emergencies in the UK?

The most commonly suggested guide is 3 to 6 months of essential expenses. Essential expenses typically include rent or mortgage, utility bills, food, transport, phone, minimum debt payments and other costs you cannot easily avoid. A 3-month fund is a solid starting target for most people. 6 months provides greater security, particularly if you are self-employed, work on a contract, or have irregular income.

There is no official "correct" amount — the right target depends on your job security, household size, income type, existing debts and other savings you have access to.

Where should I keep my emergency fund in the UK?

Most people keep their emergency fund in an easy-access savings account — one that lets you withdraw money quickly without penalties. The goal is accessibility, not growth. Common options include easy-access ISAs and standard easy-access savings accounts. Check current rates at comparison sites such as MoneySavingExpert or Compare the Market.

How quickly can I build an emergency fund?

At £200 per month saved, it takes around 9 months to build a £1,800 emergency fund covering 3 months of a household spending £600 per month on essentials. At £50 per month, the same target takes around 3 years. Starting small and being consistent is more effective than waiting until you can save a large amount.

What counts as an essential expense?

Essential expenses are costs you cannot easily reduce or stop without a significant impact on your household. These typically include housing costs (rent or mortgage), energy and water bills, council tax, food shopping, essential transport, phone and broadband, minimum debt payments, insurance premiums and childcare costs where applicable.
