If your Pay over 6 weeks credit limit doesn’t cover the cost of your purchase, you can use Boost to give you a little extra.
For example, if your credit limit is £200 and you use Boost to make a purchase of £300, you’ll pay the following instalments:
£150 (plus any fees) at checkout (the £100 Boost amount + your first £50 instalment)
£50 two weeks after the transaction date
£50 four weeks after the transaction date
£50 six weeks after the transaction date
How do I activate Zilch Boost?
You don’t need to do anything, your purchase will automatically be boosted if you spend over your credit limit. Simple.
