Emergency Savings: How Much and Where to Keep It

This article is general information, not financial advice. Consider your own circumstances or speak to a qualified adviser before acting on it.
Three to six months of essential outgoings is the usual aim. Where you hold it matters more than most guides admit, especially from April 2027.
Aim for three months of essential outgoings as a minimum, and closer to six if you are the only earner in your household or your income varies. Keep it in an easy access savings account or an easy access cash ISA with a UK-authorised bank or building society, so it is protected by the FSCS and you can reach it within a day. The part that is easy to overlook is tax: a larger fund held outside an ISA can earn more interest than your Personal Savings Allowance covers, and that matters more once savings tax rates rise in April 2027.
This guide is for you if you're setting a savings target for the first time, or you already have a cushion and want to know whether it's in the right place. It won't recommend a provider, but it will give you the checks that matter.
How much: essential outgoings, not salary
MoneyHelper, the government-backed guidance service, suggests aiming for three to six months' essential outgoings held in an instant access account. Essential means the bills that don't stop when your income does: rent or mortgage, Council Tax, energy, food, insurance, minimum debt repayments and getting to work. Takeaways, subscriptions and holidays aren't on the list.
Say your essentials come to £2,100 a month. The emergency fund calculator puts three months at £6,300 and six months at £12,600.
Where you land in that range depends on how fragile your income is:
| Your situation | Sensible target |
|---|---|
| Two steady incomes, either could cover the essentials | 3 months |
| One salaried earner | 4 to 6 months |
| Self-employed, zero-hours or commission-based pay | 6 months or more |
| Homeowner, or reliant on an older car | Add a repair buffer on top |
The reality check: this takes a while
Suppose you have £1,000 saved and can put away £250 a month. The calculator says the three-month target of £6,300 takes 22 months. Six months, £12,600, takes 47 months: nearly four years. Life doesn't pause while you save, so plan in stages.
Make your first milestone one month of essentials, which covers most boiler, car and dental surprises. Then work towards three months. If you'd rather aim for a date, the savings goal calculator shows that getting from £1,000 to £6,300 in two years takes £209.15 a month at 4% interest.
To find that money, put your take-home pay into the 50/30/20 budget calculator and look at the wants column before the needs. We'd trim wants first and set up a standing order for payday, so saving happens before spending.
Where to keep it: easy access, protected, earning interest
Your emergency fund has to be safe, reachable within a day or so, and paying something. In that order.
Protection. The Financial Services Compensation Scheme protects eligible deposits up to £120,000 per person, per authorised firm, a limit that rose from £85,000 on 1 December 2025. Watch for banking groups: brands that share one banking licence count as one firm, so two accounts with sister brands share a single £120,000 limit. That rarely affects an emergency fund, but it does if you also hold a house deposit with the same group.
Access. Notice accounts and fixed-term bonds often pay more, but you can't get the money quickly or without losing interest. They can suit the slice of your fund beyond the first couple of months. They don't suit the first month.
Interest and tax. This is where most guides go quiet. According to HMRC's guidance on tax on savings interest, the Personal Savings Allowance lets basic rate taxpayers earn £1,000 of interest tax-free, higher rate taxpayers £500 and additional rate taxpayers nothing. Interest inside an ISA doesn't count towards it. Some people on low incomes also get up to £5,000 of tax-free interest through the starting rate for savings, which shrinks by £1 for every £1 of other income above the Personal Allowance.
The surprise: a big fund can be taxed
Take the six-month fund of £12,600 above. At an illustrative 4% rate, the compound interest calculator shows it earning £513.34 in a year. A higher rate taxpayer has already gone past the £500 allowance, before counting any other savings they hold. An additional rate taxpayer pays tax on all of it.
Two announced changes make this more important. HMRC's technical note confirms savings income tax rates rise by 2 percentage points to 22%, 42% and 47% from 6 April 2027, with the Personal Savings Allowance and starting rate unchanged. And the government has decided to cut the annual cash ISA limit to £12,000 for savers under 65 from 6 April 2027, with draft regulations published for consultation in July 2026. For the 2026 to 2027 tax year, the overall ISA allowance is still £20,000.
So the practical rule: if you're a basic rate taxpayer with modest savings, a good easy access account is fine and often pays slightly more. If you're a higher or additional rate taxpayer, or your savings are large, an easy access cash ISA is usually the better home for the emergency fund. Before you open one, check the terms allow withdrawals at any time with no notice period and no loss of interest.
When to save less, or more
Don't build a six-month fund while paying high interest on credit cards or an overdraft. A common approach is one month of essentials first, then extra cash to the costliest debt, then back to the fund. Likewise, don't opt out of your workplace pension to save faster: under automatic enrolment your employer must pay at least 3% of qualifying earnings, and you give that up if you opt out. If you're unsure how to balance debt, pension and savings, MoneyHelper offers free guidance, and a regulated financial adviser can look at your full position.
The other direction: if your income is irregular or you're self-employed, six months is a floor rather than a ceiling, because a slow quarter can look like an emergency without any single bad event.
What to do next
- Next 10 minutes: add up last month's essential bills and enter them in the emergency fund calculator.
- Today: check your current savings rate, whether your provider is covered by the FSCS, and which tax band you're in.
- This week: open an easy access account or cash ISA for the fund alone, and set a standing order for the day after payday.
