What is credit card churning?

UK credit cards offer generous sign-up bonuses — cashback, Avios air miles, and rewards worth £100–£500 per card. By applying for cards strategically and using them for everyday spending to meet the minimum spend bonus requirements, you can earn significant value every year. Requires a good credit score and absolute financial discipline.

How to start credit card churning in 4 steps

  1. 1
    Check your credit score first
    Use ClearScore (completely free) to understand your current credit score. A score of 600+ gives you access to most UK reward cards.
  2. 2
    Research current sign-up bonuses
    MoneySavingExpert's credit card comparison and TopCashback list the best current UK offers. Offers change regularly, so always check the latest.
  3. 3
    Apply one card at a time
    Apply for one card, wait 3–6 months before applying for the next. This minimises the impact on your credit score while maximising bonus earnings.
  4. 4
    Hit the spend, earn the bonus
    Use the card for all regular purchases (groceries, fuel, bills). Never spend extra just to hit the minimum spend threshold — that defeats the purpose.

Frequently asked questions

Each application causes a small, temporary dip. Applying for one card every 3–6 months has minimal long-term impact if you manage the cards responsibly.
No. You don't need to spend more than you normally would. Simply route all existing purchases through the reward card and pay it off in full every month.
The American Express Preferred Rewards Gold (20,000 Avios sign-up bonus) and the BA Amex are consistently recommended as the best UK starter reward cards.
