An emergency fund is money set aside for life's curveballs — a job loss, a car repair, a broken boiler. It's the single thing that stops a bad week from becoming debt. And you build it the same way you build anything: one small, automatic step at a time.

Two targets

  • Starter goal: one month of essential expenses — or even just £500–£1,000 to begin.
  • Full goal: three to six months of essential expenses, built up over time.

How to actually build it

  1. Work out your essential monthly costs (rent, bills, food, transport).
  2. Open a separate savings account so you're not tempted to dip in.
  3. Set up an automatic transfer the day after payday — start small, even 5%.
  4. Funnel windfalls (bonuses, refunds, gifts) straight in.
💡

Keep it boring and reachable

An emergency fund isn't an investment — it should be safe and accessible within a day or two, not locked away or in something that can drop in value.
