Foundation 3 of 8
Build a safety net
An emergency fund and the right insurance stop a bad week becoming a bad decade.
This is the foundation that makes every later one safe to build on. Without a safety net, a single unexpected event — a job loss, a broken boiler, a health scare — can undo months or years of progress on everything else.
The emergency fund comes first, before investing and before extra debt repayment, because it's the thing that stops a temporary problem from becoming a permanent one.
How big should an emergency fund be?
A common starting point is three to six months of essential expenses — not your total spending, just what you'd genuinely need to cover: housing, utilities, food, and minimum debt payments. Discretionary spending isn't part of this calculation; in a real emergency, that's the first thing that would stop anyway.
Lean towards more months if your income is variable (self-employed, commission-based) or if others depend financially on you alone. Lean towards fewer if your income is stable and there are two earners in the household.
Don't wait until you can fund the whole thing before it counts. Even a partial buffer — a few hundred pounds — already prevents small shocks from turning into debt.
Where to keep an emergency fund
It needs to be accessible without delay or penalty, and not exposed to the ups and downs of investment markets — this money's job is stability, not growth. An easy-access savings account is the standard home for it.
Keep it in a separate account from your everyday spending money. Out of sight makes it far less tempting to dip into for non-emergencies, and easier to see it growing as its own thing.
Insurance you actually need
Insurance exists to protect against events that would be genuinely financially devastating — not to smooth out every small, annoying cost. The test worth applying to any policy: would this loss be catastrophic, or just inconvenient?
For most people, the priority order looks like: life insurance if someone depends on your income; income protection if you have little or no employer sick pay to fall back on; buildings and contents cover if you own property. Check what your employer already provides — many include some death-in-service or income protection benefit by default — before buying your own on top.
