Emergency Fund Checklist: How Much to Save in a UK Current Account

An emergency fund is the least glamorous part of personal finance, and the one that quietly holds everything else together. The car fails its MOT, the boiler gives up in February, your hours get cut at work — the money has to come from somewhere. The trick is choosing your number before you need it, and keeping that money somewhere you can reach on the day.

1. List your essential monthly outgoings

Start with what you genuinely cannot skip. Not what you spend, but what you must spend to keep a roof overhead and get to work. Go through three months of bank statements and pick out the repeating items.

• Rent or mortgage payment
• Council tax
• Gas, electricity and water
• Food and basic household shopping
• Transport to work — fuel, a season ticket, or the running costs of a car you rely on
• Insurance you are required to hold or would be unwise to drop: home, contents, car
• Minimum payments on credit cards, loans or car finance
• Phone, broadband and any subscription tied to a contract
• Childcare or care costs
• Prescriptions, pet essentials and school costs

Add it up. A single person renting a flat might land near £1,400 a month. A family with a mortgage and two children could easily be at £2,600. Both figures are normal. What matters is that yours comes from your statements rather than from a guess, because an emergency fund built on the wrong number is either too small to help or so large it stalls everything else.

2. Choose how many months of cover you need

There is no universal right answer here, but there are sensible ranges, and the deciding factor is how quickly you could replace your income.

Three months — a reasonable floor

Suits a two-income household in stable employment, with no dependants relying on a single wage, and where a job change would probably mean weeks rather than months out of work.

Six months — the usual target

The right sort of figure for most households: one main earner, a mortgage, children, or a sector where roles take a while to come up. Six months of essentials covers a redundancy period, a notice period and the gap before a first new payday.

Nine to twelve months — worth considering

If you are self-employed, on fixed-term contracts, the sole earner for a family, living with a health condition that could interrupt work, or in an industry where hiring slows sharply. Add months rather than pounds here. It is easier to reason about time than about abstract amounts.

Write your chosen number down. Vague intentions never get funded.

3. Turn it into a single figure — and a monthly amount

Multiply essentials by months. Say your essentials come to £1,800 a month and you want six months of cover: £1,800 × 6 = £10,800. Round it up to £11,000 for a little breathing room.

Then subtract what you already have set aside. If there is £1,400 in a savings account doing nothing in particular, your real gap is £9,600.

That can look daunting. Divide it by a timeframe you can live with. Over 24 months, £9,600 is £400 a month. If that is too much right now, do not abandon the plan — set a starter target of £1,000 first, then £2,000, and keep the full figure as the destination rather than the entry fee.

4. Decide where the money lives

An emergency fund has one job: to be available. That rules out anything with a lock on it.

Keep a small float — a few hundred pounds — in your current account so a surprise bill does not bounce a direct debit. Put the rest in an easy-access savings account you can withdraw from the same day, or at worst within a day or two. Notice accounts paying a little more can work, but only if the notice period is short enough that you would not be caught out by a genuine emergency.

Cash ISAs are a sensible home if you expect to earn interest above your personal savings allowance, since interest inside an ISA is not taxed. Premium Bonds are another option many people use, though prize returns are not guaranteed and withdrawals can take a few working days. Avoid fixed-rate bonds, and avoid investing this money — a market dip is not an emergency, but it is a terrible time to sell.

One more thing: the Financial Services Compensation Scheme protects up to £85,000 per person, per bank. If your fund is anywhere near that, or you are holding large balances across accounts under the same banking licence, it is worth checking how your money is covered.

5. Build it in the right order

1. Start with a £500 buffer. Small enough to reach quickly, big enough to stop most everyday shocks turning into debt.
2. Deal with expensive debt. If you are paying a high rate of interest, a modest buffer plus steady repayments usually beats hoarding cash. If debt feels unmanageable, free, impartial help is available from Citizens Advice and StepChange.
3. Automate a standing order. Set it for the day after payday, when the money has not yet been mentally spent.
4. Send windfalls straight there. A tax rebate, a bonus, a sold bike. These accelerate the fund faster than any amount of budgeting.
5. Review it once a year. Rent rises, a new child, a paid-off loan — all change the target. Update the number at the same time you review your insurance.

6. Know when to use it, and how to refill

An emergency is unexpected, necessary and urgent. Losing your job, a broken boiler in winter, a car repair you need to keep working, essential travel for a family crisis. It is not a sale, a holiday, a wedding gift or Christmas — those are planned costs, and they belong in a separate savings pot.

When you do spend from the fund, treat the refill as a temporary bill. Work out what you can put back monthly and set a date to be whole again. Do not wait for a windfall.

Your next 30 minutes

Open your banking app and total up your essential outgoings from last month. Multiply by the number of months you decided on. Subtract what you already hold in savings. That figure is your target, and it is now written down rather than floating around in your head.

Then set up one standing order, however small, to an easy-access account. The first payment matters more than the amount.

This is general information rather than personal financial advice. If your circumstances are complicated — mixed debts, self-employment income, or a large lump sum to place — a regulated adviser can help you fit the fund into a wider plan.
