One unexpected bill or a boiler breakdown can throw everything off course, especially if turning to credit is the only option to deal with it. An emergency fund could be a safety blanket for costs like these that we just don’t see coming.

When money’s tight, saving can feel out of reach. But you don’t need to build a large pot straight away. Starting with a small amount, when you can afford to, can still give you more breathing room over time.

What is an emergency fund?

An emergency fund is a savings pot for unexpected, urgent and essential costs. For example:

  • Your car needs an urgent repair
  • An essential appliance stops working
  • Your income suddenly drops or stops

It’s there to give you a bit of a financial cushion when life doesn’t go to plan.

Emergency fund vs a planned cost fund: what is the difference?

An emergency fund is for something unexpected. Sometimes, it’s called a rainy day fund.

It’s different from a planned cost fund. A planned cost fund is for a cost you know is coming up. For example, you might put money aside each month for Christmas, an MOT, a holiday or annual insurance.

Keeping the two separate can make it easier to see what money is available for each purpose. If you’re saving for a known cost, look at our guide to building a planned cost fund.

Why having an emergency fund can help

Without savings to fall back on, it can be tempting to use a credit card, loan or Buy Now Pay Later when something goes wrong. That may solve the immediate problem, but it can make your budget harder to manage later and could lead to fees and charges if you can’t repay it.

Even a small emergency fund can help you:

  • Avoid taking on more borrowing where possible
  • Feel more prepared for the unexpected

There’s no right amount to have saved. What matters is building a habit that works with your budget.

How much should I save in an emergency fund?

Start with what you can afford, even if that’s £1 a week or £5 at the end of the month.

You might choose a small first goal. Once you reach it, you can decide whether you want to keep building your fund.

Our free BudgetSmart tool can help you understand where your money’s going and find manageable ways to plan ahead.

How to start an emergency fund

Choose a small, realistic amount

Set aside an amount that feels manageable. It could be a few pounds each week, or a small amount after payday.

Keep it separate from day-to-day spending

If you can, keep your emergency fund in a separate easy-access savings account or savings pot. This can make it less tempting to spend on things that aren’t emergencies.

Make sure you can still get to the money quickly if you need it.

Review subscriptions and regular spending

Look through your regular payments to see whether there’s anything you no longer use or need. Cancelling one unused subscription could free up money for your savings pot.

You don’t need to cut out everything you enjoy. The aim is to make choices that feel realistic and sustainable.

When should you use your emergency fund?

Before using the money, ask yourself:

  1. Was this cost unexpected?
  2. Is it urgent?
  3. Is it essential?

If the answer’s yes to all three, it may be the right time to use your emergency fund.
