Emergency Fund Checklist: How Much to Save and Where to Keep It

An emergency fund is the least exciting part of any financial plan, and the one you'll be gladdest to have. It's the money that turns a broken boiler or a surprise redundancy from a crisis into an inconvenience. The problem is that most advice stops at "save three to six months of expenses" and leaves two questions hanging: three to six months of what, exactly, and where is it supposed to live? Here's a practical checklist covering both, plus the part people forget — knowing when to actually spend it.

What actually counts as an emergency

An emergency fund is for costs that are unexpected, unavoidable and urgent. The boiler fails in January. The car needs a repair you can't postpone if you want to keep getting to work. You're made redundant and the first payment won't land for a month. Those qualify.

Plenty of things that feel urgent don't. Christmas, a wedding, a car service, insurance renewals and the summer holiday are all predictable — you just don't know the exact figure yet. They belong in a separate sinking fund, saved for month by month, so they never touch your emergency money.

The test is simple. Could you have seen this coming with a bit of planning? If yes, it's a planned cost. If no, and it genuinely can't wait, it's an emergency.

How much should you save?

The standard answer is three to six months of essential outgoings — not your income. Add up what you must pay each month: rent or mortgage, council tax, utilities, food, transport, insurance, childcare and minimum debt payments. Leave out the gym, the streaming subscriptions and the takeaways you'd drop without much pain.

Say your essentials come to £1,800 a month. A three-month fund is £5,400; six months is £10,800. That's a large number, which is exactly why you build it in stages: a £1,000 starter buffer first, then one month, then three.

Lean towards six months or more if your income is variable or you're self-employed, you're the only earner at home, you have dependants, or your industry goes through regular rounds of redundancies. Three months is a reasonable target if you have a secure job, two incomes and no dependants.

Building the fund: a working checklist

1. Work out your essentials. One number, written down.
2. Set two targets. A starter buffer of £1,000 and a full target of three to six months.
3. Automate it. A standing order the day after payday beats good intentions. Even £50 a month builds the habit.
4. Name the account. Something like "Do not touch" makes the withdrawal screen feel different.
5. Send windfalls there. Tax rebates, bonuses, birthday money, the old phone you finally sell.
6. Bump it up when your pay rises. Pushing half the increase into savings keeps it painless.
7. Keep planned costs out. Use a sinking fund for those instead.

Where to keep it

Your priorities are access, safety and a decent rate — roughly in that order.

• Easy access savings account. The default choice. Read the terms, though: some accounts that call themselves easy access limit you to a set number of withdrawals a year before the rate drops.
• A linked savings pot. Many current accounts let you create a named pot in seconds. Lower rates, unbeatable convenience.
• NS&I Direct Saver. Deposits are backed by HM Treasury rather than the Financial Services Compensation Scheme.
• Cash ISA. Worth considering once the interest on your savings starts to exceed your Personal Savings Allowance — £1,000 for basic-rate taxpayers, £500 for higher-rate, and nothing for additional-rate.
• Notice accounts and fixed-term bonds. Better rates, but your money is tied up. Fine for the slice of your fund you're confident you won't need, not for all of it.
• Premium Bonds. Safe and usually quick to withdraw, within a few working days. But the prize rate is not a guarantee, and plenty of holders win nothing in a year.

Whichever provider you use, check the FSCS protection limit — currently £85,000 per person, per bank or building society — if you're holding large balances across brands that share a licence.

A common approach is to split the fund. Keep one month's expenses somewhere you can reach in minutes, and the rest in a better-paying easy access account. Spreading it across two accounts also makes it less tempting to spend in one go.

Where not to keep it

Not in investments. Stocks and shares can fall sharply just when you need the cash, which is the wrong kind of timing entirely. Avoid long fixed-rate bonds with withdrawal penalties, anything you'd have to sell to release money, and the current account you spend from daily. A small amount of cash at home is sensible for a day or two of disruption — not more.

When to use the money — and when to leave it alone

Spend it when the alternative is expensive borrowing or going without something essential: redundancy, an urgent repair, necessary travel for a family emergency.

Don't spend it on a sale, a holiday, a house deposit top-up or a "can't miss" investment tip. If you do dip in, treat it as a loan to yourself and rebuild it before adding to any other savings goal.

One caveat worth taking seriously: if you're carrying high-interest debt while trying to build a big fund, a small buffer plus free debt advice is often the better order of events. Citizens Advice, StepChange and National Debtline all offer free guidance, and a regulated adviser is worth speaking to if your situation is complicated. Money and tax rules change, so check current figures and seek professional advice where it matters.

Keeping the fund in good shape

Once it's built, it needs very little attention — but not none. Diarise a yearly check: does the balance still cover three to six months of your current essentials? Have you changed jobs, moved house, had a child or taken on a bigger mortgage? Your target should move with your life.

Check the rate at the same time. Loyalty rarely pays with savings accounts, and moving money to a better-paying account takes twenty minutes. Confirm you can still get at the cash quickly, and make sure your partner or a trusted person knows where it is and how to reach it.

Finally, if you've used the fund, restart the standing order the same week. The aim isn't a perfect figure sitting in an account — it's knowing that when something goes wrong, you've already dealt with the money side of it.
