Bills and Utilities

1. Switch energy tariff using Uswitch or Ofgem comparison — save £200 to £400 per year

4. Use cashback grocery apps — Shopmium and Checkout Smart save £20 to £50 per month

3. Compare fuel prices at Petrolprices.com — savings of 5 to 10p per litre add up quickly
4. Use annual or monthly transport season tickets for regular commutes

Banking and Finance

1. Switch to a cashback credit card — earn £100 to £400 per year on everyday spending
2. Move savings to a 5%+ easy-access account rather than leaving cash in a 0.1% current account
