An emergency fund is your financial safety net—money set aside for life's unexpected moments. But if you're starting from zero, building one can feel impossible. Here's how to get started, even on a tight budget.

Why You Need an Emergency Fund

Without savings, every unexpected expense becomes a crisis:

  • Car repairs go on credit cards
  • Medical bills create debt
  • Job loss becomes devastating
  • Home emergencies cause panic

An emergency fund turns potential disasters into minor inconveniences.

ℹ️ The Reality

44% of UK adults couldn't cover an unexpected £400 expense without borrowing. Don't be part of that statistic.

How Much Do You Need?

Starter Emergency Fund: £1,000

This covers most minor emergencies and is your first goal. It prevents small surprises from derailing your finances.

Full Emergency Fund: 3-6 Months Expenses

Calculate your essential monthly expenses and multiply by 3-6. This protects against job loss and major emergencies.

Step 1: Find the Money

"I don't have money to save" is common but rarely completely true. Try:

  • Track spending: Find £50-100/month you didn't know you were spending
  • Cancel subscriptions: Unused gym, streaming, apps
  • Reduce one category: Dining out, coffee shops, entertainment
  • Sell items: Declutter and sell what you don't use
  • Side income: Even a few hours/week adds up

Step 2: Automate Your Savings

Make saving automatic so you don't have to think about it:

  • Set up standing order on payday
  • Transfer before you see the money in your current account
  • Start small—even £25/week is £1,300/year
  • Increase amount as you adjust

Step 3: Keep It Separate

Your emergency fund should be:

  • Separate account: Not in your daily spending account
  • Accessible: Can get to it within 1-2 days
  • But not too easy: Separate bank adds helpful friction

💡 The Best Account

Easy-access savings account at a different bank than your current account. Earns interest, accessible in emergencies, but not in your face daily.

Quick Wins to Boost Your Fund

  • Tax refund: Put at least half toward emergency fund
  • Work bonus: Save it before you spend it
  • Birthday money: Treat yourself with part, save the rest
  • Selling items: Direct cash from sales to savings
  • Reduced bills: When you cut a bill, save the difference

The Savings Challenges

Make saving a game:

  • 52-week challenge: Save £1 week 1, £2 week 2... £1,378 by year end
  • No-spend days: Every no-spend day, save what you would have spent
  • Round-up: Round up purchases and save the difference
  • Matched savings: Every time you buy something non-essential, save the same amount

What Counts as an Emergency?

Use your fund only for true emergencies:

  • Job loss or significant income reduction
  • Medical emergencies
  • Essential car repairs (if you need it for work)
  • Emergency home repairs (broken boiler, roof leak)
  • Unexpected essential travel (family emergency)

⚠️ Not Emergencies

Sales, holidays, new gadgets, planned expenses you forgot about, and "I really want it" are NOT emergencies. Be strict with yourself.

After You Use It: Replenish

When you use your emergency fund:

  • Feel good—this is what it's for!
  • Immediately prioritize rebuilding it
  • Pause other savings goals temporarily if needed
  • Find extra income or cut expenses to refill faster
