What is an emergency fund?

Cash you can reach quickly, set aside for genuine surprises: the boiler dying, the car failing its MOT, losing work. A common guideline is 3 to 6 months of essential outgoings (your “needs” number from Budgeting Basics). If that feels impossible, start with a mini-goal: even £500 prevents many emergencies becoming debts.
