Cushion · What you can absorb · 7 min read
From nothing to six months' expenses: the ladder
You do not need six months’ savings by Friday. Build in rungs: £100 in cash at home, then one month of essential bills in easy-access savings, then three, then six. MoneyHelper, the government-backed guidance service, suggests three months’ essential outgoings as a solid cushion (moneyhelper.org.uk, checked 26 August 2026).
Why a ladder, not a leap
“Six months of expenses” is the figure that makes people close the tab. It sounds like a mountain, so most households never start: only 17% of UK adults keep any emergency cash at home (LINK Cash Index, published May 2026), and the savings picture is not much cheerier.
A ladder works because each rung is useful on its own. £100 in a drawer gets you through a weekend of failed card machines. One month of bills turns a broken boiler from a crisis into an annoyance. You are safer at every rung, not just at the top.
This page describes what MoneyHelper and other official bodies say. It is not financial advice, and we never recommend particular banks or products.
The four rungs
| Rung | Target | What it absorbs |
|---|---|---|
| 1 | £100 cash at home, in small notes | Card and payment outages, a few days of essentials |
| 2 | One month of essential bills, easy access | A big repair, a vet bill, a quiet month if you’re self-employed |
| 3 | Three months of essential bills | Losing a job, illness, a run of bad luck |
| 4 | Six months of essential bills | A long illness, retraining, a slow house move |
Rung 1 is covered properly in how much cash to keep at home. The rest of this page is about rungs 2 to 4.
What does MoneyHelper actually recommend?
MoneyHelper is the free, government-backed money guidance service, and its emergency savings guidance is the closest thing the UK has to an official answer. It suggests having at least three months’ essential outgoings available in an instant-access savings account, with three to six months described as a solid financial cushion. Its worked example: if you spend £1,000 a month on rent or mortgage, food, heating and other things you cannot live without, aim for £3,000 to £6,000.

Notice what that target is based on: essential outgoings, not your full monthly spending. That single distinction usually shrinks the mountain by a third.
What counts as an essential bill?
The things you would keep paying if your income stopped tomorrow. Typically:
- Rent or mortgage
- Council tax
- Energy and water
- Food and household basics
- Getting to work or school
- Insurance you already hold
- Minimum payments on any debts
- Phone and broadband
- Childcare you cannot pause
Subscriptions, eating out, holidays and hobbies do not count. In a genuinely bad month you would pause them, so the fund does not need to cover them.
How to work out your number
Add up a normal month of essentials, then multiply. Here is a worked example; the figures are for illustration only, so write in your own.
| Essential | Example monthly cost |
|---|---|
| Rent or mortgage | £950 |
| Council tax | £140 |
| Energy | £150 |
| Water | £40 |
| Food and household basics | £400 |
| Transport | £120 |
| Insurance | £50 |
| Phone and broadband | £50 |
| Total | £1,900 |
For this household the rungs are £1,900 (one month), £5,700 (three months) and £11,400 (six months). Your numbers will differ, but the method is the same: one honest month of essentials, times one, three, six.
Where should the money live?
The point of this money is that you can reach it in days, without penalty, so emergency savings generally sit in easy-access accounts rather than fixed-term ones. MoneyHelper’s guidance points at instant-access savings for exactly this reason. We do not recommend providers; any comparison of easy-access rates will show you the current field.
Money in a UK-authorised bank, building society or credit union is protected by the Financial Services Compensation Scheme up to £120,000 per person, per institution (FSCS, checked 26 August 2026). Temporary high balances, such as house sale proceeds, are protected up to £1.4 million for six months (FSCS). For an emergency fund, the practical takeaway is simple: money in a protected account is not the risky part of your life.
The automatic version
The rung you never think about is the one that gets built. The standard method is a standing order from your current account to your savings account, dated the day after payday, for an amount you will not miss.
Start embarrassingly small if you need to. £25 a month is £300 a year, which is rung 1 and change. When a bill ends, a phone contract finishes or pay rises, redirect the difference before you get used to it.
When do you use it, and when do you refill?
Use it for the things it was built for: the income stops, the boiler dies, the car that gets you to work fails its MOT. A sale is not an emergency, and neither is Christmas, which is predictable enough to save for separately.
When you do spend it, that is the fund working, not a failure. Drop back down the ladder without guilt, restart the standing order, and climb again. If you find yourself using it every month, the problem is the monthly budget rather than the fund, and MoneyHelper’s budgeting guidance is the place to start.
If you have not started anything yet, how to start covers the first week, and the cushion pillar shows where savings sit alongside alerts and paperwork.
Frequently asked questions
How much emergency fund do I need in the UK?
MoneyHelper suggests at least three months’ essential outgoings in instant-access savings, with three to six months as a solid cushion. Count essentials only: rent or mortgage, bills, food, transport, minimum debt payments. In the worked example above, the three-month rung is £5,700, but your own bills set the number.
Why start with £100 in cash?
Because it is the only rung that works when the banking system itself has the bad day. In the April 2025 Iberian blackout, when parts of the peninsula lost power for up to 19 hours (NESO, checked 26 August 2026), card payments failed widely, as reported at the time. Small notes cover food and fuel until systems come back.
Is three months enough, or do I need six?
MoneyHelper’s range is three to six months of essentials. Three suits households with steady income and two earners; six gives self-employed people, single earners and anyone with patchy income more road. Reach three first and decide from there. Either is far better than none.
Should emergency savings go in a fixed-rate account?
The defining feature of an emergency is that it will not wait for a maturity date. That is why MoneyHelper’s guidance points at instant-access accounts for this money. Fixed-term and notice accounts can suit other goals, where the money is not your safety net.
What if I can only save a little each month?
Then save a little each month. £10 a week reaches the £100 cash rung in under three months and £500 within the year. The ladder does not care how fast you climb it, only that the standing order keeps running.
Is my money safe in a savings account?
Deposits with UK-authorised banks, building societies and credit unions are protected by the FSCS up to £120,000 per person, per institution (FSCS, checked 26 August 2026). If a firm fails, compensation is automatic. Keep a balance above that limit and it is worth reading the FSCS’s guidance on spreading money across institutions.
When is it OK to spend the fund?
When the thing it exists for happens: lost income, essential repairs, an emergency that will not wait for payday. Spend it without guilt, then treat refilling it as the next goal. It is a tool, not a trophy.
