Emergency fund guide: how much and where to keep it
Important: This guide gives general information, not personal financial advice. We don’t quote savings rates here, as they change often. For dated rates, see our easy-access savings page.
Last updated: .
An emergency fund is money set aside for the unexpected, such as a broken boiler, a car repair or a drop in income. Having one means you’re less likely to turn to a credit card or overdraft when something goes wrong.
In this guide we’ll look at how much to aim for, where to keep it, and how to build it step by step. We’ll also cover what counts as an emergency, and how the fund fits alongside debt, benefits and other savings goals.
Quick answer
- MoneyHelper suggests three to six months of essential outgoings as a rule of thumb.
- Any amount helps, so start small if you need to.
- Keep it somewhere you can reach quickly, such as an easy-access savings account.
- Keep it separate from your everyday spending money.
- Pay off expensive debt such as credit cards and payday loans first, according to MoneyHelper.
- Savings can affect means-tested benefits such as Universal Credit.
- Check your money is protected by the FSCS, up to £120,000 per eligible person per authorised firm (source: FSCS).
Who this guide is for
It’s for anyone in the UK who wants a financial safety net, whether you’re starting from nothing or reviewing what you already have. It also covers couples, people with irregular income and people claiming benefits.
What an emergency fund is for
Your emergency fund covers essential costs if your income stops or a big, unexpected bill arrives. Essentials usually include:
- rent or mortgage payments
- council tax
- energy and water bills
- food
- travel to work
- essential insurance
- minimum payments on any debts
It isn’t for holidays, presents or planned purchases. Those work better as separate savings goals, which we cover below.
How much to aim for
MoneyHelper suggests aiming for three to six months of essential outgoings, held in an instant access account. For example, if your essentials cost £1,000 a month, that’s £3,000 to £6,000.
That can feel like a lot. MoneyHelper also says any amount saved will help, so don’t let the target put you off starting.
Some people with irregular income, such as the self-employed, choose to hold more than six months. That’s a personal choice, not an official target.
Working out your essentials
Go through your bank statements for the last few months. Add up the essentials listed above, and leave out things you could cut in an emergency.
Our budget planner can help you work out your monthly essentials. If you’re new to budgeting, our guide to a simple budget for beginners is a good place to begin.
Worked examples
These examples are illustrations only. Your own figures will differ.
Example one. A single renter has essential outgoings of £1,400 a month. Three months of essentials comes to £4,200.
Example two. A family with a mortgage has essential outgoings of £2,800 a month. Six months of essentials comes to £16,800.
Example three. A self-employed worker’s income goes up and down from month to month. They might decide to keep more than six months of essentials, to cover quieter periods.
Starting smaller
If a full fund feels out of reach, it can help to set smaller milestones. For example:
- £500
- £1,000
- one month of essentials
- three months of essentials
These are illustrative steps, not rules. Each one gives you a bit more breathing room.
Where to keep your emergency fund
The main thing is that you can get at the money quickly, and that it’s safe. Here are the common options.
| Option | Access | How people often use it | Main trade-off |
|---|---|---|---|
| Easy-access savings account | Usually same day or next working day | The core emergency fund | Rates are variable and can change |
| Notice savings account | After a notice period, such as 30 or 90 days | Money beyond the first month or two of essentials | You can’t get the money straight away |
| Easy-access cash ISA | Usually quick, depending on the provider | Larger funds where interest might be taxed | Uses part of your ISA allowance |
| Current account or spending pot | Instant | A small buffer for very short-term needs | Easy to dip into without meaning to |
| Premium Bonds | You can cash in at any time | Some people hold part of their fund here | You might not win any prizes, so you could earn nothing |

Easy-access savings
Easy-access accounts let you withdraw money when you need it. This makes them a common home for an emergency fund. Our guide to opening a first savings account explains how to get started.
Notice accounts
Notice accounts may pay more, but you need to give notice before taking money out. Some people keep one month of essentials in easy access, and the rest in a notice account. See our guide to notice vs easy-access savings.
Fixed-rate accounts usually lock your money away for a set period, which doesn’t suit an emergency fund. Our guide to easy-access or fixed-rate savings compares the two.
Cash ISAs
Interest in a cash ISA is tax-free. This matters more if your fund is large enough that interest might go over your Personal Savings Allowance. That allowance is £1,000 for basic-rate taxpayers and £500 for higher-rate taxpayers.
The ISA allowance is £20,000 for the 2026/27 tax year (source: GOV.UK). From 6 April 2027, people under 65 will be able to put no more than £12,000 a year into cash ISAs.
Tax rates on savings interest outside ISAs will also rise by 2 percentage points from April 2027. Our guide to ISAs vs savings accounts explains the trade-offs.
Premium Bonds
Premium Bonds are run by NS&I and backed by HM Treasury, rather than the FSCS. You can hold between £25 and £50,000, and cash in at any time.
Instead of interest, you’re entered into a monthly prize draw. There’s no certainty of winning, so you might not earn anything. Our guide to Premium Bonds vs a savings account compares them.
Is your emergency fund protected?
Money in UK banks, building societies and credit unions is protected by the Financial Services Compensation Scheme. From 1 December 2025, the limit is £120,000 per eligible person per authorised firm (source: FSCS).
Some brands share a banking licence and count as one firm. If you hold savings with more than one brand, check whether they share a licence.
For short periods, the FSCS can also protect temporary high balances of up to £1.4 million for six months, for example after a house sale. Our guide to FSCS protection limits has the details.
How to build your fund
Open a separate account. Keeping your emergency fund apart from your spending money makes it less tempting to dip into. Give it a clear name if your bank allows it.
Automate it. Set up a standing order for the day after payday. Choose an amount you can afford every month, even if it’s small.
Add windfalls. Tax refunds, birthday money or a bonus can give your fund a boost. So can cashback you’ve earned on everyday spending; see our cashback and rewards hub.
Review your budget. Look for one or two regular costs you could cut, and send the savings to your fund.
Pause other saving goals, if needed. Some people pause extra investing while they build a buffer. Investments can fall as well as rise, so having cash first can help you avoid selling at a bad time.
An example six-month plan
This is one possible approach, not a set plan.
- Month one: open a separate account and set up a standing order you can afford.
- Months two and three: add any windfalls, and sell a few things you no longer use.
- Month four: review your essentials and cut one regular cost you don’t need.
- Months five and six: raise your standing order if a bill has gone down or your pay has gone up.
Debt first or emergency fund first?
MoneyHelper suggests paying off expensive or urgent debts before building up a large emergency fund. These include credit card debt, unauthorised overdrafts, payday loans, home credit and mortgage arrears.
If your other borrowing is low-cost or under control, building the fund can make sense. Some people keep a small buffer while they clear debt, so they don’t need to borrow again for a surprise bill.
Our guide on whether to pay off debt or save explains the trade-offs. If you’re struggling with debt, MoneyHelper, StepChange and Citizens Advice offer free help.
What counts as an emergency
It helps to decide this in advance, so you’re not tempted to use the fund for other things.
Usually counts as an emergency:
- losing your job or a sudden drop in income
- urgent home repairs, such as a broken boiler or a leaking roof
- car repairs you need to get to work
- unexpected medical or vet bills
- emergency travel
Usually doesn’t count:
- holidays
- Christmas and birthday presents
- sales and special offers
- planned purchases, such as a new phone
If you do use the fund, plan to top it back up when you can.
Emergency fund vs sinking funds
A sinking fund is money you set aside for a cost you know is coming, such as Christmas, car servicing or an annual insurance bill. Keeping these separate from your emergency fund stops planned costs eating into your safety net.
Our Christmas budgeting guide shows how a sinking fund works for seasonal spending.
Couples and joint savings
Couples can keep a joint emergency fund, separate funds, or a mix. It helps to agree how much you’re aiming for and what counts as an emergency.
For joint accounts, each eligible account holder is protected by the FSCS up to £120,000 per authorised firm. Our guide to joint savings accounts covers the options.
If you’re self-employed
If you’re self-employed, keep your tax money separate from your emergency fund. A dedicated tax pot means you won’t mistake money owed to HMRC for spare savings.
Some people with irregular income also choose a larger emergency fund, to smooth out quieter months.
Emergency savings and benefits
Savings can affect means-tested benefits. For Universal Credit, savings over £6,000 reduce your payment by £4.35 for every £250 you have between £6,000 and £16,000. If you have more than £16,000, you usually can’t claim.
Our Universal Credit calculator guide explains more.
Help to Save
If you get certain benefits, including some Universal Credit claimants, you may be able to use Help to Save. You can save between £1 and £50 a month, and the government adds a bonus of 50p for every £1 you save over four years. Check eligibility and current terms on GOV.UK.
Where not to chase a higher return
An emergency fund needs to be safe and easy to reach. That rules out some options:
- cryptocurrency, which can swing sharply in value
- individual shares or other investments, which can fall when you need the money
- long fixed-rate accounts, which lock your money away
A slightly lower return is the price of being able to get your money quickly.
The catch
The catch: an emergency fund on its own won’t grow much. Easy-access rates are variable, and over time inflation may reduce what your money can buy.
That’s the trade-off for keeping it safe and accessible. Savings above certain levels can also affect benefits such as Universal Credit.

FAQ
How many months of spending do I need in my emergency fund?
It depends on your situation. MoneyHelper suggests three to six months of essential outgoings as a rule of thumb. Any amount helps, so it’s fine to start smaller and build up.
Can I keep my emergency savings in a cash ISA?
Yes. An easy-access cash ISA can work if you can withdraw quickly. It uses part of your ISA allowance, and from 6 April 2027 people under 65 will be able to put no more than £12,000 a year into cash ISAs.
Is it OK to keep emergency money in Premium Bonds?
It depends on what you want from your fund. You can cash in Premium Bonds at any time, and they’re backed by HM Treasury. But you might not win any prizes, so you could earn nothing.
What counts as a real emergency?
It depends on your circumstances, but it usually means something urgent and unplanned. Losing income, urgent home or car repairs and unexpected medical or vet bills usually count. Holidays and presents usually don’t.
Could my emergency savings reduce my Universal Credit?
Yes, if you have more than £6,000. Savings between £6,000 and £16,000 reduce your payment by £4.35 for every £250. With more than £16,000, you usually can’t claim.
