An emergency fund is one of the most important financial tools you can have, providing peace of mind and a safety net when unexpected expenses come your way. Whether it’s an urgent car repair, medical bills, or a sudden job loss, having money set aside helps you avoid dipping into debt. But how much should you save? And where’s the best place to keep that money?

How Much Should You Save in Your Emergency Fund?

The ideal size of your emergency fund depends on your income stability, expenses, and risk tolerance. Here are some common guidelines:

  • 2 to 3 months of essential expenses: If you're just starting out, aim to save at least two months' worth of necessary expenses—like rent or mortgage payments, bills, groceries, and insurance. This is a good baseline for short-term emergencies such as car repairs or minor income disruptions
  • 6 months of expenses: For most people, a fund covering six months of living costs is a solid goal. This allows you to handle larger financial challenges, like a period of unemployment or significant unexpected expenses, without needing to take on debt
  • 12 months of expenses: For higher earners or those with less stable income—such as freelancers, contractors, or small business owners—a larger fund might be more appropriate. A year’s worth of essential expenses can offer greater peace of mind if your income is irregular or if you're in an industry prone to fluctuations

Can You Save Too Much?

While a healthy emergency fund is essential, keeping too much in cash could mean missed opportunities. Once you've saved enough to cover your emergency goal, you may want to think about investing any excess in something like a Stocks and Shares ISA (Individual Savings Account).

With inflation, the value of your cash savings gradually erodes, and since bank accounts generally offer low interest rates, your purchasing power diminishes over time. By investing in a tax-efficient vehicle like an ISA, your money has the chance to grow and outpace inflation, though you should always be aware of the risks involved in investing.

Premium Bonds: A Safe Place for Part of Your Emergency Fund?

Some people choose to hold part of their emergency fund in Premium Bonds, offered by National Savings and Investments (NS&I). Premium Bonds don’t pay interest, but you have the chance to win tax-free prizes through monthly draws, with amounts ranging from £25 to £1 million.

A major benefit is that Premium Bonds are fully backed by the UK government, so your money is 100% secure. This makes them a reliable option for those who are risk-averse. However, if you don’t win any prizes, the value of your savings will gradually decrease due to inflation. This is why Premium Bonds are best suited for only part of your emergency fund, while the majority can be placed in higher-interest accounts for better returns.

Where Should You Keep Your Emergency Fund?

Choosing the right place to store your emergency savings is important. You want your money to be easily accessible, but also secure. Here are some options:

1. Easy Access Savings Accounts

An easy access savings account is often the first port of call for emergency savings. These accounts allow you to withdraw money quickly when you need it, which is crucial for emergencies. While interest rates are typically lower than fixed-term accounts, you can still find competitive rates by shopping around.

2. Multiple Bank Accounts for Added Security

It can be a smart idea to spread your emergency fund across more than one bank account. Here’s why:

  • Peace of mind: If one of your accounts is frozen—for example, if you’re the victim of fraud—you’ll still have access to money in a second account. This gives you an extra layer of security, especially if you rely on a single income stream.
  • FSCS Protection: The Financial Services Compensation Scheme (FSCS) guarantees up to £85,000 per person, per banking group. If you have more than this amount saved, keeping your money in different banks ensures that all of it is protected, even in the unlikely event that a bank collapses.

3. Notice Accounts

If you're looking to earn a higher interest rate and don’t need instant access to all of your emergency fund, you could consider placing some money in a notice account. These accounts require you to give notice—usually between 30 to 90 days—before withdrawing. This might not be ideal for immediate emergencies, but it can be useful for less urgent financial needs.

4. Premium Bonds

As mentioned earlier, Premium Bonds offer a government-backed, secure place to park some of your savings. You can withdraw the funds at any time, making them accessible, but be mindful that you won’t earn any interest unless you win prizes.

Automating Your Savings

If you’re still building your emergency fund, automating your savings is a great way to ensure you’re consistently putting money aside. Set up a standing order or direct debit from your current account to your savings account each month. Start small, even £50 or £100 per month, and gradually increase the amount as you’re able to. Over time, your fund will grow, and you’ll develop a healthy savings habit without even thinking about it.

Striking the Right Balance

An emergency fund is your first line of defence against life’s financial surprises. Whether you’re aiming to save two, six, or twelve months' worth of expenses, the key is having enough easily accessible cash to cover the unexpected. Once you reach your target, consider whether any surplus can be invested in a tax-efficient ISA or similar vehicle to protect your savings from inflation.

By spreading your emergency fund across different accounts and using tools like Premium Bonds for added security, you ensure that your savings are both safe and accessible when you need them most.
