Emergency funds: how much, and where to keep it
The short answer
Three to six months of essential spending, not of income. Essentials are usually a good deal less than take-home pay, which makes the target smaller and more reachable than most people expect.
Instant access, in a separate account. The rate is the least important feature. Money you cannot reach within a day is not an emergency fund, whatever it is earning.
Start with one month. The gap between nothing and one month is the one that changes how a bad week feels. Everything after that is refinement.
The safety net is thinner than people assume. Statutory sick pay is £123.25 a week, and a new Universal Credit claim normally takes five weeks to pay. That gap is what the fund is really for.
Size it from your essentials, not your salary
Advice to save three to six months of income is common and unhelpful, because it produces a number so large that people give up before starting. What you would actually need in a crisis is the cost of keeping the household running, which is a different and smaller figure.
Count rent or mortgage, council tax, energy, water, food, insurance, phone and internet, transport to work, childcare, prescriptions and the minimum payments on any debts. Leave out holidays, subscriptions you would cancel, eating out and clothes beyond replacement. For many households the essentials come to somewhere between half and two thirds of take-home pay, which means three months of essentials is closer to six or seven weeks of salary.

Then choose a multiple based on how quickly you could replace your income and what would happen in the meantime.
| Circumstances | Reasonable target |
|---|---|
| Secure employment, good occupational sick pay, no dependants, partner also earning | Around three months of essentials. Your employer and your household are already absorbing part of the risk. |
| Single income household, or dependants, or a mortgage | Closer to six months. More people rely on the income and the fixed costs are harder to cut quickly. |
| Self-employed, contractor, commission-heavy or seasonal work | Six months or more, and treat it as working capital as well as emergency money. There is no sick pay behind you. |
| Specialised role, small local job market, or a long notice-to-hire cycle | Six months upwards, because the constraint is how long a search takes rather than how well you cope. |
| Older home, older car, or a known upcoming cost | Add the likely repair on top rather than counting it within the months. A boiler and a redundancy can happen in the same quarter. |
Why the target is what it is
The three-to-six-month convention makes more sense once you look at what actually arrives if your income stops.
Statutory sick pay
From 6 April 2026, statutory sick pay is the lower of £123.25 a week or 80% of your average weekly earnings, calculated over the eight weeks before the absence, and payable for up to 28 weeks.
Two changes took effect on the same date and both are improvements. The three waiting days have gone, so it is paid from the first full day of absence rather than the fourth. The lower earnings limit has gone too, so there is no longer a minimum you must earn to qualify, and lower-paid employees receive 80% of their average earnings where that is less than the flat rate.
It remains a small amount of money. For most households £123.25 a week does not cover the essentials, which is the entire argument for holding a buffer. Many employers pay contractual sick pay well above the statutory minimum, sometimes full pay for several months, and that single fact changes how large a fund you need. It is worth knowing what your contract says before you need to know.
Universal Credit
A new Universal Credit claim normally takes five weeks to reach first payment, because it runs on a monthly assessment period followed by processing. The standard allowances for 2026/27, from 6 April 2026, are £424.90 a month for a single claimant aged 25 or over, £338.58 if under 25, £666.97 for joint claimants where one or both are 25 or over, and £528.34 where both are under 25. Additional elements for children, housing and limited capability for work may apply on top, and deductions can reduce what actually arrives.
An advance is available if you cannot wait the five weeks, and it is worth knowing the terms before you need it.
Five weeks with no income, followed by a reduced payment while an advance is recovered, is a precise description of what an emergency fund is protecting you from.
Where to keep it
The requirements are ordinary: reachable within a day, held separately from your current account so it is not spent by accident, and protected. Interest is a bonus rather than the objective. Over a few months the difference between a good rate and an excellent one on a modest balance is small, and it is not worth accepting any restriction on access to capture it.
The accessible layer
An instant access or easy access savings account holds the part you might need this week. Rates on these move constantly, so rather than quote a figure that would be stale within weeks, check a comparison table on the day you open one, and read past the headline. A leading rate frequently includes a temporary introductory bonus that drops after a year, requires a linked current account, limits how many withdrawals you can make, or applies only up to a certain balance. Any of those can make a slightly lower rate the better account.
Cash ISAs suit this purpose well if you are near your personal savings allowance, since the interest is tax free. The overall ISA subscription limit for 2026/27 is £20,000.
Anything above the accessible layer
Notice accounts typically require 30 to 120 days' warning before a withdrawal. Give the notice properly and access is usually penalty free, but early access may be refused outright, allowed only in exceptional circumstances, or cost you interest equivalent to the notice period. A 90-day notice account is not where next week's boiler repair should sit.
Fixed term bonds commonly run from six months to five years. Some permit no withdrawal at all before maturity. Where early access is allowed, the penalty is usually a set number of months' interest, and in some cases the account closes. Before committing, check whether early withdrawal is permitted, whether partial withdrawals are allowed, whether the penalty is loss of interest or a charge, and whether that penalty can eat into your original capital.
Both have a place once your accessible reserve is complete. Neither is a substitute for it.

Making sure it is protected
The Financial Services Compensation Scheme protects eligible deposits up to £120,000 per person, per authorised firm. This rose from £85,000 on 1 December 2025, so older articles quoting the smaller figure are simply out of date. It covers current accounts, savings accounts, cash ISAs and savings bonds. A joint account is normally protected to £240,000, because each holder has an individual limit.
The critical detail is that the limit attaches to the banking licence, not the brand. Several familiar names share a single authorised firm, and money held across them is added together for the purposes of the limit. Halifax and Bank of Scotland sit under one licence, as do HSBC UK and first direct, and Barclays and Tesco Bank. Lloyds Bank is a separate authorised firm from Bank of Scotland, and the announced rebranding of Halifax does not change that treatment.
Brands and legal entities move around, so rather than trusting any list, including this one, check the specific account using the FSCS bank and savings protection checker. That is the only version that is current for your account today.
For an emergency fund of ordinary size none of this bites, since almost nobody holds six months of essentials anywhere near £120,000. It matters at the moments when a large sum passes through your account, which tend to be exactly the moments people are distracted.
If you are on a low income
Help to Save is a government scheme paying a 50% bonus on money saved, which is a return no savings account can match. You can save between £1 and £50 a calendar month, up to £2,400 over four years, with a bonus after two years based on your highest balance and a further bonus after four years based on any increase during years three and four. The maximum total bonus is £1,200, and it is paid into your bank account rather than into the Help to Save account.
Eligibility currently covers people receiving Universal Credit who had take-home pay of at least £1 in the previous monthly assessment period, and those receiving Working Tax Credit or meeting the relevant tax credit conditions. The earnings threshold that previously applied was removed in April 2025. Both partners in a joint Universal Credit claim can apply separately if each qualifies. Accounts can be opened until April 2027 under the current extension, and each account runs for four years from opening.
One caveat worth knowing in advance: savings and bonuses can count as capital for Universal Credit means testing, even though the bonus is not treated as income. That rarely bites at these amounts, but it is better known than discovered.
Building it without a spare month's income
Almost nobody assembles this in one go, and the amount matters less than the fact that it exists.
- Set the first target at one month of essentials, or even £500. A fund that covers one bad week is dramatically better than none, and reaching a target is what sustains the habit.
- Move the money the day you are paid, by standing order, rather than saving whatever survives the month. What survives the month is usually nothing.
- Keep it somewhere slightly inconvenient. A different bank from your current account, with no card attached, adds enough friction to stop casual spending without preventing a genuine transfer.
- Clear expensive debt first, but not all of it. Paying 25% credit card interest while earning 4% on savings loses money. The exception is holding a small buffer regardless, because someone with nothing set aside puts the next emergency straight back on the card.
- Refill it after you use it. Using the fund is not a failure, it is the fund working. The failure is not rebuilding it afterwards.
What it is not for
An emergency fund covers things that are unexpected, necessary and urgent. A car failing its MOT qualifies. A car you have wanted for a while does not. Christmas is not an emergency, and neither is a holiday, an excess on a claim you knew was coming, or the annual insurance renewal. Those are predictable costs that belong in ordinary budgeting.
Keeping the distinction is what stops the fund quietly becoming a current account with a different name. If you find yourself dipping into it regularly, the usual cause is that the monthly budget is missing some genuinely recurring costs rather than that emergencies keep happening.
