Bottom Line

The fastest wins come from switching providers (energy, insurance, phone — takes 30 minutes each) and switching supermarkets (Aldi/Lidl save 20–30%). Then automate your savings: set up a standing order on payday to move 20% into a high-interest Cash ISA or easy-access account. The key is making saving automatic and painless.
